Foreword
Exce llent surgical outcomes in rhinoplasty derive from two interrelated fac tors: (1) a de tailed understanding of the multiple nasal anatomic varian ts encountered, and (2) an ac qui red knowledge of the ulti mate long-term effects of surgical altera tions of these anatomic components-the evo lution of healing. The first ski ll ca n be learned by detailed observation, enhanced by cadaver dissection; the second skill only by ca reful foll ow-up of ope rated patients over time. The genera l con cepts of nasal anatomy have been fun damentally clear for centuries , but on ly in recent decades have surgeons appreciated the fine ly det ailed nuances of nasal anatomic dynamic s that influence the surgical crea tion of a natural, plea sing rhinopl asty re sult, free of surgical stigmata. A det ailed com prehension of nasal anatomy must therefore transcend knowledge of basic anatomic relationships. Th e surgeo n must j udge , by inspec tion and pa lpation, the character of the ski n and subcutaneous tiss ues as they vary from nasal region to region , the influences of faci al mimetic musculature, the relative strength and support of the carti laginous and bony framework and substruct ure, and the lim itations imposed by the int err elation ship of all these struc tures upon the ultimat e fav orable result. As important as the eva luation of what can reasonably be accomplished during rhi noplasty is the acqui red kno wledge and ski ll to assess what canno t be acco mplished. This ju dgment is largel y pre dicated on the critical ana lysis of each pat ient's indivi dual anatomy, coupled with techn ical refin ements guided by experie nce, and generally requires years of personal surgic al result evaluation to beco me kee n. In this diss ection manu al, Drs. Becker and Toriumi have created a unique study guide and cadaver dissection manu al ded icated to guiding the learn er in a disciplined manner. They admirably ex tend the tradit ion of the Universi ty of Illinois Departm ent of Oto laryn gology's leader ship in teaching anatomy and surgery in rhin oplasty. Cadaver dissec tion cons titutes a privil ege not available to all, and, as such, this precious material must be wise ly and co nserva tive ly approached . Experie nce teaches that a discipl ined, structured ap proach to dissecti on of the nose pro duces the best edu cational outcome . An imp ortant fav orable develop ment in cont empo rary rhinoplasty is the appropria te con ce rn for conservative and subtle anatomic changes that by definition derives from a prese r vativ e attitude toward nasal tissues. Commonly, rath er than excisional sacrifice of large segments of cartilage or bon e, a phil osophy of preservation and restoration oftissues is de ve loping that preclud es crea tion of unnecessary tissue voids whic h may heal and scar un

predictably. Wise surgeons recognize that even a larger nose, well balanced to the rounding facial features, is always aesthetically preferable to a nose made over-sma radical surgery. Conservation surgery thereby further extends the surgeon's control the final surgical result, as an appropriate equilibrium between the corrected nasal ske and soft tissue covering is more reliably achieved. Con servative sculpture and volum duction of the alar cartilages clearly produce more favorable results, generally avoi major resections and vertical interruprion of the intact residual strip of lateral and m crus. Notching, pinching, alar cephalic retraction, over-rotation, and asymmetries ar almost entirely eliminated in long-term healing when this conservative philosophy is braced . A further striking example of conservatism is the preservation of a strong , high file in many patients, a distinct contrast to the dramatic retrousee pro files create decades past by sacrifice of over-generous segments of nasal bony humps. Finally, thoughtful nasal surgeons, through accurate anatomic diagnosis , discern w portions of the nasal anatomy are pleasing and satisfactory, striving to avoid distur these structures and areas when correcting (or gaining access to) anatomic componen need of correction. This philosophy further extends the surgeon 's favorable control ove timate healing. Thoughtful cadaver dissection provides the learner with visual pathwa gain access to structures to be modified, while preserving normal tissues and relations Important tissue planes, vital in live surgery, can be appreciated best when viewed at le in the dissection laboratory. This well-conceived work, properly employed, contributes substantially to shorte the steep learning curve characteristic of rhinoplasty.

Preface
The successful rhinoplasty surgeo n' s operative plan is based on a clear understanding of the patient's desired changes, a care ful and accurate diag nosis of the patient's anatomy , and a wide armamentarium of surgica l techniques. Prior techniques and the surgeon's personal experiences with the array of surgical techniques are also primary factors in the decision for a particular operative approach. The successful surgeon's applicatio n of surgica l tech niques is designed to accom modate differences in anatomy and to account for varia nt anatomy. For example, noses with thin skin and noses with thick skin each present specific problems that must be considered when choosing techniques for altering nasal struc ture. Also, the effec ts of scar contracture vary from patie nt to patient and can significantly affec t the ultimate aesthetic and functional outcome . The rhinoplasty surgeo n must recognize that the healing process may distort the cha nges made at the time of surge ry, however ex pert ly they were accomplished. The surgeon's only recourse is to build a structurally sound nasal architecture that can withstand the force s of scar contracture and provide an acceptable suc cess rate. The importance of experience in rhinopl asty cannot be overemphasized. The experi enced rhinoplasty surgeon can anticipate the likelihood of a favorable outcome based on his or her experience using certain techniqu es with a specific deformi ty. Selec tion of the proper technique for each circ umsta nce should provide the opportunity for a high success rate. The purpose of this dissec tion manual is to provide practical infor mation about a wide range of surg ical techn iques in rhinoplasty. The dissection ma nual guides the reader through a step-by-step dissection. It focuse s on the execution of basic and advanced rhino plasty techniques and seeks to provide practical information that can be readily applied in surgery. The text is intended to be a procedurally oriented dissection manual and is orga nized to allow easy reference to a wide array of basic and advanced rhinoplasty techniques. Illustrations and intraoperative photograph s, along with detailed text, guide the reader through the step-by-step dissection. Important techn ical and clinical "pearls" are high lighted in each section. A progra mmatic cadaver dissection videotape acco mpanies the text. Before beginning the nasal dissection, review the chapter on nasal anatomy (Chapter 1) and the chapter on pre-operative rhinoplasty analysis (Chapter 2). Chapter 3 outlines local anesthesia injec tion techniqu es; the dissector is instructed to practice the injections prior to commenci ng the programm atic dissection.

Appro priate targeted reference s for further readi ng are also pro vided . We recommend that the diss ector pro ceed with Chapters 1- 6 with the skin-so ft tiss velope intact. For the remai ning chapters, the dissector may wish to split the ski n dow midl ine for better exposur e. In this fashi on, the dissection can be performed withou t sista nt, and (except for a complete septopl asty) without a he ad light. The cadav er laboratory is the plac e to sharpen one ' s sur gical skills.

1 Anatomy
Although the anatomy of the nose has been fundamentally understood for many years, only relatively recently has there been an increased understanding of the long-term effects of surgical changes on the function and appearance of the nose. A detailed understanding of nasal anatomy is critical for successful rhinoplasty. This chapter reviews the surface and structural anatomy of the nose, with an emphasis on important surgical anatomy. Accurate assessment ofthe anatomic variations presented by a patient allows the surgeon to develop a rational and realistic surgical plan. Furthermore, recognizing variant or aber rant anatomy is critical to preventing functional compromise or untoward aesthetic results. This chapter presents a limited diagrammatic overview of nasal anatomy. More detailed study of nasal and facial anatomy is recommended (1) (Figs. 1-10).

PEARLS
The nose may be thought of in anatomic thirds . The upper third roughly corre sponds to the bony dorsum; the middle third roughly corresponds to the cartilagi nous dorsum; and the lower third generally corresponds to the tip. o When describing relationships of one structure to another in the nose, use the well . defined anterior/posterior or caudal/cephalic. (Fig. II). . o The nasal bones are usually small; the ascending process of the maxilla provides a significant contribution to the bony anatomy of the nose. o The alar lobule contain s fat and fibrous connective tissue, but it contains no carti lage. The lateral crus of the lower lateral cartilage takes on a more cephalic posi tion as it extends laterally and is not found in the alar lobule. o The lobule, alar lobule, and the infratip lobule are terms that designate three dis tinct anatomic areas of the nose. The lower third of the nose may be referred to as the lobule or tip. The alar lobule is a fibrofatty nasal subunit that is devoid of car- . tilage and compose s a portion of the lateral nasal sidewall . The infratip lobule o

2 Rhinoplasty Analysis
Development of an oper ative plan that will achieve the desired outcome requires an under standing of the patient' s wishes and selection of appropriate surgical maneuvers to effect the propo sed changes. Th e surgeon mu st be able to identify anatomic con straints that will limit the ability to change contour (thick skin, weak cartilages, etc.). Experi ence with rhino plasty over time has sho wn that detailed anatomic analysis of the nose is an essentia l first step in achieving a successful outc ome. Failure to recognize a particular anatomic point preoperatively will often lead to a less than ideal long-term result. After you have identified the various anatomic landmarks in Chapter 1, undertake a pre operative rhinoplasty analysis of your patient (cadaver specimen) . In this programmatic dissection, you will perform a number of incisions, approaches, and surgic al techniques, but it is also important to develop your skills in rhinoplasty analysis. Repe ated practice of rhinoplasty-analysis skills will improve your preoperative diagno stic abilit y. Therefore, in this exercise, determine what the best approach and techniques would be in your specime n. Follow the simplified rhinoplasty-analysis algorithm provided as you examine the face and nose. Also provided is a more detailed description of terms and a more detailed review of rhinoplasty analysis.

RHINOPLASTY ANALYSIS
A thorough phy sical examination and accurate preoperative anal ysis are cr achieving the desired long-term postoperative rhinoplasty result. Some degree of organization assi sts in the execution of the physical examination. Visual examinat finger palpation are equally important in the nasal evaluation. Throughout the eva a mental image of the potential outcome and surgical limitations inherent in every ual should be visualized. In effect, the potential rhinoplasty operation is rehearsed the physical examination proceeds (1,6). Study of the stand ard preoperative photographic images for rhinoplasty (fronta lateral, oblique) allows a systematic, detailed anatomic anal ysis that complements th ical examination proce ss. Thi s chapter focuse s on analy sis of the four standard rhin photographic views (frontal, base, lateral , oblique). Emphasis is placed on ana to scriptions of structures and their relationships to other structures. Analysis begins by examining all four view s and making an assessment of the stature of the patient , the facial skin quality , and the symmetry of the face . The prin dividing the face into horizontal thirds and vertical fifths is a useful tool to obtain a sense of any incongruent areas of the face that may playa key role in nasal appeara the outcome of nasal surgery. It is essential that these incongruent areas or asymme recognized and discus sed with the patient. Thickness and quality of the facial skin taneous tissue complex must be determined, as it plays a critical role in dictating t tations of what can and cannot be accompli shed with aesthetic nasal surgery (1,6,7 After completing the general assessment, note and highlight the most striking ch istics of the nose. These are typically the characteristics that bring the patient fo plasty , such as excessive size, deviation , or a dorsal hump. These primary patient c must be recognized, highlighted, and addres sed above all else. As the surgeon reviews each photographic image, the major aesthetic and te points that can be evaluated on a given view are noted first. Subtleties in analysis a addressed. It is important to recognize both the characteristics of greatest concern to tient and the more subtle findings. The patient may not notice these other subtle ab ities if they are left unaddressed by the surgeon. Postoperatively, the scrutinizing may notice and point out these abnormalities. Stepwise, methodical analysis of the and the photographic view s allows the well-trained surgeon to identify significant an and aesthetic point s.

Frontal View On frontal view, the observant surgeon first notes nasal width, any deviation from the midline , and characteristics of the nasal tip . Nasal width can be assessed in the upper, mid dle, and lower third of the nose. It is important to recognize that a saddle deformity of the bony or cartilaginous dorsum will contribute to the appearance of an overwide dorsum on front al view, whereas a hump will give the impression of a narrow dorsum. Simil arly, a low bony dorsum will create an illusion of a relatively wide upper third of the nose and wide in tercanthal distance or pseudohypertelorisrn (7). This appearance can be significantly im proved by augmenting the nasal dorsum . The width of the nasal base on frontal view should approximate the interc anthal distance. The contour of the curved aesthetic lines that follow the eyebrows, traverse the radix, and continue down along the lateral nasal dorsum to end at the tip-defining points (the brow-tip aesth etic lines) should be followed , and any asymmetries, twists , or dev iation s noted. The se brow-tip aesthetic lines should be smooth, unbroken , gentl y curved, and symmetric (1,6) . The nasal tip should be characterized on frontal view with regard to symmetry and def inition. Concavity or other anatomic findings of the alar sidewall are noted. Vertical and horizontal aspects of bulbosity should be recognized when present. Bifidity of the nasal tip may be visible on this view (but is typically best appreciated on base view) . The gentle "gull-in-flight" relationship of the nasal alae to the infratip lobule should be followed , and any asymmetry should be noted. Exaggeration of this curve is suggestive of alar retraction and/or a dependent infratip lobule. If the columella is not visible ("hidden columella") on frontal view, this also may indicate a retracted columella. The vertical position and sym metry of the alar insertions should be described on the front al view. Base View On base view, special attention should be given to triangularity, symmetry, columella/lob ule ratio, and width and insertion of the alar base. The nasal base should be configured as an isosceles triangle with a gently rounded apex at the nasal tip and subtle flaring of the alar sidewalls (Fig . 3) (4,8,9). Poor triangularity or trapezoidal configuration with broad domal angles may suggest abnormal divergence of the intermediate crura . The presence of asym metry of the tip may best be appreciated on this view. Often one can visualize the outline of

Variations in the appearance of w base view may be due to the variation in horizontal position of the alar insert face or in the flare of the alar sidewalls. The alar sidewalls themselves are ch with regard to thickness and flare. Alar base insertions are described by degree ture , with straight insertions going directly into the face (i.e., no nostril sill) , and recurved alae inserting directly into the columella (4,8,9) . The ratio of the columella to lobule should approximate a 2: 1 ratio, and the b the flare of the medial crural footplates should divide the alar base into halves. T are commonly oriented 30 to 45 degrees toward the midline and are pear-shape gated. The facets or external soft-tissue triangles are attractive when they are w but can detract if they are overly conspicuous (4,8,9).
Lateral View
The lateral view offers important information on tip projection, nasal length, do and alar-columellar relationship. The nasal tip should ideally project strongly from the the face and gracefu supratip dorsum, creating a modest supratip break. An identifiable but not over ated columellar double break typically marks the junction of the medial and in crus . Nasal tip projection is consistently assessed by using the method describe (see Fig. 2) (2,3). If the length of a line drawn from the tip-defining point perpe a tangent to the alar-facial junction is greater than 0.55 to 0.60 of the line draw nasion to tip-defining point, then the nose ma y be overprojected. However, whe tip projection, relationships between the nose and other aesthetic facial features jection, forehead contour, ethnic background, etc.) must be considered. Nasal length is complicated to define. The nasal length is compared with the thirds of the face and the overall stature of the patient to determine whether th appropriate length. However, the factors contributing to the appearance of nasa complex. The nose can be considered to have three lengths, with nasion to tip be trallength , and nasion to alar margin being the lateral lengths. A short or long la may reflect a retracted or hooded ala, respectively, whereas a ShOl1 or long cen may reflect an obtuse or acute nasolabial (columellar-labial) angle, respective more, a deep nasofrontal angle contributes to the illu sion of a short nose, and a sofrontal angle adds apparent length to the nose (10). In Fig . 4A, three diagram except for the nasofrontal angle illustrate the effect of the nasofrontal angle on ance of nasal length. Another three diagrams (Fig. 4B), identical except for the angle, illustrate the effect of the nasolabial angle on the appearance of length. The nature of the columellar-labial confluence and columellar-lobular ang break) also must be assessed. Webbing or tenting of the columellar-labial should be noted. An overly obtuse columellar- labial angle and/or an exaggera break will make the nose appear ShOI1, whereas the converse (acute columella gle and/or absent double break) will add apparent length. A posteriorly inclinin ficiency of the premaxilla may confound accurate measurement of the colum

Byrd (5) described a useful method for determining appropriate aesth etic proportions for tip projection, nasal length , and radix projection. "Ideal" nasal length is two third s of the midfacial height and is equ al to chin vertical. Tip projection is ideall y two thirds of this planned or ide al nasal length. Radix projection may be measured from the junction of the nasal bones with the orbit and ideally should be one third of the calculated nasal length.

Other notable comp onents of the dorsum includ start ing point, which is ideally positioned at the level of the superior palpebral f tip-supratip relationship, as previousl y mentioned. The ala is analyzed in detail on the lateral view. Insertion of the ala on the fac above the columella in the horizontal plane, as described by Crumley (4), is j normal. The contour of the alar rim in profile ideally approximates a "lazy S" should note if this is normal, exaggerated, or straight. The size of the alar lobu ficd as small , normal , or large.

This is a reliable determinant of operative rotation of the nasal tip (7). Oblique View
Although it offers the least amount of objective data, this is an important aesthe cause the nose is most often seen at oblique angles.

3 Injection
INFILTRATIVE ANESTHESIA TECHNIQUE Proper local anesthesia is critical to allow atraumatic dissection with minimal bleed ing and edema. A total volume of less than 3 ml of 1 % lidocaine with 1: 100,000 epinephrine is typically used to attain anesthesia for rhinoplasty alone. When performing septorhinoplasty, as much as 10 ml of local anesthetic may be used. The anesthetic is al lowed to take effect for at least 15 minutes to maximize the vasoconstrictive effect of the epinephrine. To become familiar with a method of injection of local anesthetic agent, saline can be in jected with a 5-ml syringe and 27 gauge (1.5 ern) needle along the site of injection in your cadaver specimen. Injection varies in some respects, based on the surgical approach se lected; for example, the subdermal columellar injection may be omitted in an endonasal ap proach. A generalized approach to injection is described below. For a septoplasty, multiple 0.5-ml to 1.0 rnl injections are made in the subperichondrial and subperiosteal plane along the entire area of anticipated dissection . Injections also should be placed along the site of the proposed incision (Killian, hemitransfixion, etc.). Both sides of the septum should be in jected if the surgeon plans to elevate mucosa bilaterally. The injection will aid in the dis section if placed in the subperichondrial plane . It is helpful to place an injection on the pos terosuperior septum bilaterally to minimize bleeding from the sphenopalatine blood vessels. Inject local anesthetic into the subdermal plane in the midline of the columella from tip defining points to the nasal spine in preparation for the external approach (Fig. I). This in jection is limited to < 0.3 ml to prevent distortion of the columella or nasal base. For either endonasal or external approach, inject < 0.3 ml of local anesthesia into the soft-tissue be tween and around the domes of the lower lateral cartilages (Fig. 2). The injection extends up to the region of the anterior septal angle . After completing this injection, gently massage the domal region between the thumb and index finger of both hands to disperse the anes thetic throughout the tip region. Place multiple injections of 0.1 ml of local anesthetic along the caudal margin of the lateral and intermediate crura (along the planned marginal inci sion; Fig. 3). Overinjection will result in distortion of the nostril rim and soft-tissue trian gle. Inject <0.1 ml to raise a small bleb in the vestibular skin along the lateral aspect of the

medial crura, at the planned incision site for the columellar flap of the external rhinoplasty approach (Fig. 4). For an intercartilaginous, transcartilaginous, or delivery approach, place similar injec tions of 0.1 ml intranasally along the respective incision sites (Fig. 5). After inserting the needle between the upper and lower lateral cartilages (intercartilagi nous), inject local anesthetic along the lateral wall of the nose approximately 1 ern off the midline (Fig. 6). The line of injection is along the lateral aspect of the nose and extends from the nasofrontal suture line to the cephalic margin of the lateral crura . Use <0.5 ml for this injection to prevent distortion of the tissues. Perform no injections along the dorsum of the nose to prevent distortion of the soft tissue that may inhibit accurate evaluation of the contour of the dorsum. In preparation for lateral osteotomies, inject on the outside and in side of the nasal bones just above the periosteum. After completing these injections , mas sage the injection sites to help disperse the local anesthetic and prevent tissue distortion.

Avoid excessive injection of local anesthetic into the columell a; otherwise th lation between the ala and columella may be altered. In cases in which dorsal hump excision must extend into the region of the sofrontal angle, additional injection s of local ane~thetic can be placed along path of the supratrochlear artery and just medial to the medial canthus . If the surgeon plans to use lateral crural strut.grafts, injection s of local anest can be placed in the vestibular skin on the undersurface of the lateral crura w the vestibular skin will be dissected.

NASAL DISSECTION: SEPTOPLASTY WITH CARTILAGE HARVEST Hemitransfixion Incision with Anterior Septal Tunnels 1. Retra ct the colum ella with a small nasal speculum, multi toothed Brown-Adson forceps, large two-pron g hook , or another suitable instrument. Thi s maneuver exposes the cau dal margin of the septum ( 1,2). 2. Make a hemitran sfixion incision along the caud al borde r of the cartilag inous septum with a no. 15 blade or no. 15-C blade . In this exercise, a hemitransfixion incision ex tendin g from the anteri or septal angle to the posterior septal angle is used to gain access to the caudal septum. A Killian incision can be used if acce ss to the caudal septum is not necessary (Fig . IA ). 3. In rare cases, the nasal spine should be exposed . 4. With a no. 15 blade, small, sharp -pointed scissors, or other suitabl e instrument, incise the perichondrium of the septum adjacent to the caudal septum on one side . 5. Perform a subperichondrial dissection along the lower half of the septum to allow har vesting of septal cartilage. Do not extend this diss ection too high, so that later in the dis section a precise pock et tunnel can be made to place a spreader graft via an endon asal approach. 6. Repeat maneuv er 5 on the oppo site side of the septum. 7 . If the septum needs any shortening, now may be a good time to perform selective exci sion of the caud al aspect of the septum (Fig. IB-D). If rotat ion of the nasal tip is neces sary, a superiorly based triangle of caudal septum can be excised (Appendix F). For an obtus e nasolabial angle, the posterior septal angle can be trimmed . For a tension nose deformity (3) or hangin g-columell a deformity, the entire caudal septum may need to be trimmed. Instead of resection, an overly long midlin e caud al septum can be sutured be tween the medi al crura to provide support, increa se proje ction, and set tip-rotation and alar-columellar relation.

Septal Surgery with Harvesting of Cartilage Carry out a routine septoplasty or submucous-resection operation. To harvest septal car tilage, disarticulate the cartilaginous septum from its bony attachment (osseocartilaginous junction), leaving an ample attachment superiorly (dorsally) at the "Keystone" area . Incise the cartilage dor sall y and caudally, preserving 2 15 mm anteriorly to support the nasal tip, and being sure that 215 mm will remain dorsaJly afte r hump removal (Fig. 2). Preserve this harvested septal cartilage for use as struts or grafts later on in this exercise. If inadequate septal cartilage is available, plan to harvest auricular cartilage for grafting purposes. Note: We have described septoplasty via a hernitransfixion or a Killian' s incisi on. A vi able alternative is to approach the caudal septum dire ctly by performing an extern al rhin o plasty approach and separating the medial crura, thereby coming upon the caudal septum (Fig . 3). Septoplasty may then proceed as described earlier. Although this approa ch avoids the need for a septal mucosal incision, it is a more complex approach and carries with it a higher risk of loss of tip support if appropriate supportive maneuvers (e.g., columellar strut , caudal extension graft) are not undertaken. This approach is ideal in patients who have an overly long midline caudal septum (tension nose deformity). In these cases, the medial crura can be dropped back and sutured to the midline caudal septum. Thi s maneuver will allow shortening of the nose, deprojection of the nasal tip, or correction of the hanging col umella deformity .

To perform septorhinoplasty, a viable approach to the septum is to perform an external rhino plasty approach and separate the medial crura , thereby coming upon the caudal septum , and then pro ceeding with elevation of mucoperichondrial and mucoperiosteal flaps in standard fashion. Before dis section, local anesthetic should be injected between the medial crura and into the vestibular skin caudal to the caudal septum. While an assistant holds the lower lateral cartilages laterally (A) , the surgeon dis sects between the medial crura (B) until the caudal septum is identified (e). Special care must be taken to remain in the proper plane between the crura. The mucoperichondrial flaps are next further developed with an elevator (D). The dorsal septum can be divided from the upper lateral cartilages in an anterior to-posterior direction (E) after both mucoperichondrial flaps have been elevated to the junction of the up per lateral cartilage and septum (extramucosal dissection). This will allow preservation of continuity of the intranasal mucosa while dividing the upper lateral cartilages from the dorsal septum. Bilateral mu coperichondrial flaps are developed for wide access to the septum (F). Appropr iate support ive maneu vers (e.g., columellar strut, caudal extension graft) are undertaken because of the risk of loss of tip sup port. With an overly long caudal septum, the medial crura can be sutured back on a midline caudal septum to provide support and set tip position.

5 Incisions and Approaches
Incisions are methods of gaining access to the bony and cartilaginous structures of the nose and include transcartilaginous, intercartilaginous, marginal, and transcolumellar incisions. Approaches provide surgical exposure of the nasal structures including the nasal tip and in clude cartilage-splitting (transcartilaginous incision), retrograde (intercartilaginous inci sion with retrograde dissection), delivery approach (intercartilaginous, marginal incisions), and external (transcolumellar and marginal incisions). Based on an analysi s of the individ ual patient's anatomy, appropriate incisions, approaches, and tip-sculpturing techniques are selected (I) (Appendix E). , In this section , a transcartilaginous incision is performed on one side. Then an intercar tilaginous and marginal incision is made on the other side to deliver that cartilage. Next, proceed with the external rhinopl asty approach. Following these instructions will allow an experience with several incisions and approaches in a single specimen.
TRANSCARTILAGINOUS INCISION OR CARTILAGE-SPLITTING APPROACH As demonstrated in the accompanying figure s, use a two-prong retractor and the middle finger of the nondominant hand to expose the lower lateral cartilage (LLC). Locate the caudal and cephali c margins of the lateral crura. (The surgeon must identify the cephalically positioned lateral crus when it is present before executing this incision.) Make an incision through vestibular skin only 5 mm to 8 mm cephalic to the caudal mar gin of the lateral crus of the LLC incision . Figure I illustrates the site of a transcartilagi nous incision and the more ceph alic location of an intercartilaginous incision. With scis sors, dissect free the vestibular skin in a cephalic direction to just beyond the cephalic edge of the lateral crus (Fig. 2). Then incise the lateral crural cartilage and free the cephalic por tion (to be removed) from its remaining soft-tissue attachments by dissecting superficial to it in the supraperichondrial plane . Use a skin hook to retract the caudal vestibular skin and another skin hook to retract the nostril margin. An assistant may hold the skin hook that re tracts the nostril margin, while the surgeon grasps the cartilage to be removed and com pletes the excision by dividing any last soft-tissue attachments with scissors (Fig. 3) (1,2).

Free the cephalic portion (to be removed) from its re maining soft-tissue attachments by dissecting superficial to it in the supraperichondrial plane. Grasp the cartilage to be removed , and com plete the excision by dividing any last soft-tissue attachments with scissors . B: The cartilage incision must come far enough medially to in clude the cephalic lateral crus at the dome region , or else supratip full ness may persist. However, it is im portant not to incise too far infero medially, or the cartilage (which is typically narrow at this region) may be excessively weakened or divided. C: A 3D-gauge needle placed percu taneously at the dome can help guide the medial aspect of the tran scartilaginous incision in selected cases.
DELIVERY APPROACH (PERFORM ON SIDE OPPOSITE CARTILAGE SPLITTING APPROACH) Intercartilaginous Incision
By using a two-prong retra ctor , evert the caudal margin of the nostril and , by ap pressure with the middle finger of the nondominant hand, reveal the gap between t dal margin of the upper lateral and the cephalic margin of the lower lateral cartilage a sca lpel, make an intercartilaginous incision in this location (Fig . 4) (1,2).

Figure 4. A-C: Intercartilaginous incision. D: For an intercartilaginous approach, bilateral intercartilaginous incisions are connected in the midline over the anterior septal angle, and the incision extends anterior to the caudal septum as a high partial-transfixion incision . Ex posure of the middle and upper nasal vault proceed as described in the text. E: After com pletion of the intercartilaginous approach, a Converse retractor (or other appropriate retrac tor) may be inserted through the incisions, beneath the skin/soft-tissue envelope, to provide exposure of the upper two thirds of the nose.
Marginal Incision By using a two-prong retractor, evert the caudal margin of the nostril in which an inter cartilaginous incision was made and, by applying pressure with the middle finger of the nondominant hand, define the caudal margin of the lower lateral cartilage. Pressing cepha lad on the nasal dome will cause the caudal margin to appear laterally. Remember that the non-hair-bearing area is a guide to the caudal margin of the lateral crus. Furthermore, pal pation of the cartilage edge with the handle of the scalpel can be helpful before cutting. By using the two-prong retractor to obtain proper exposure, make the marginal incision just caudal to the caudal edge of the lower lateral cartilage (Fig. 5). Great care must be taken as the lateral incision nears the midline. Make sure that the incision follows the cartilage edge and does not take a "short-cut" along the alar rim, which can damage the facet area. Great care must be taken not to cut across a narrow dome or intermediate crus (1,2).
Delivery of lower lateral cartilages At this stage, an intercartilaginous incision and marginal incision on one side and a transcartilaginous incision on the other side have been made. Reinsert the two-prong re tractor into the nostril with the intercartilaginous and marginal incisions and present the caudal margin of the lower lateral cartilage with the aid of pressure from the third finger of the nondominant hand. Use a slightly curved, fine-pointed dissecting scissors to lift and dissect the soft tissues from the surface of the lower lateral cartilage (Fig. 6). Perform this dissection by inserting scissors into the marginal incision laterally and then separate the perichondrium of the lower lateral from the overlying external skin and soft tissue with a spreading motion. If this is difficult, caudal traction on the vestibular skin underlying the lower lateral cartilage, with a fine two-prong hook, will facilitate this maneuver (Fig. 7) by pulling the lateral crus into the vestibule and thus opening up the potential dissecting plane. Avoid damaging the overlying muscle and nasal vasculature (1,2).

THE EXTERNAL (OPEN) RHINOPLASTY APPROACH Background The external rhinoplasty approach to the nose provides ma ximal exposure of the lower lateral cartilages, upper lateral cartilages (Ul.Cs) , middl e nasal vault, and bon y nasal vault. These supportive structures can be manipulated in a precise and sym metric fashion . The in creased exp osure facilitates accurate suture placement and fixation of cartilage grafts. The external rhinoplasty approach also facilitates diagnostic capability and is a tremendous aid in teaching rhinoplasty (3-10) (Appendix K). The incisions used in this app roach include a transcolumellar incision connected to bi lateral marginal incisions. The actu al configuration of the tran scolumellar inci sion is not as critical as the placement of the inci sion . The incision should be made at the level of the mid columella where the caudal margins of the medial crura lie close to the skin and can sup port the incision to help prevent a depressed scar. An inverted-V incision , or some other broken -line incision, is used to break up the scar and lengthen it to minimize scar contrac ture. The surgical dissection must be performed in the proper areolar tissue planes to min imize tissue damage and scarring, maintain hemostasis, and maximize redraping of the skin/soft-tissue envelope. Dissection in proper tissue planes will help preserve vascular structures of the flap , ensure flap viability, and minimize bleeding, postoperative edema, and scarring ( I I) .
NASAL DISSECTION: EXTERNAL (OPEN) RHINOPLASTY APPROACH Marking the Transcolumellar Incision Begin the dissection by outlining the transcolumellar incision used in the external rhino plasty approach with a marking pen . Mark an inverted-V transcolumellar inci sion at the level of the midcolumella (Fig. 9). The midcolumellar incision should be marked midway between the top of the nostril and the base of the columella, where the caudal margin of the medial crura lie just beneath the skin, to provide support for the incision. The midcolumel lar incision will be connected to bilateral marginal inci sion s, which are placed ju st caudal to the caud al margin of the lateral crura (Fig. 10). The marginal incision should not be made along the rim of the nostril (rim inci sion). The marginal incision may be marked with a marking pen as well.

Midcolumellar Incision By using a no. 11 blade with a "sawing" motion, follow the midcolurnellar markin gs to complete the midcolumellar incision (Fig. 11). Proceed medial to lateral on one side of the columella and then the other. Take special care to keep the blade perpendicular to the skin edges, thereby preventing beveling of the skin edges. (Beveling of the skin edges may lead to a "trapdoor" deformity with eventual unacceptable scar). While incising laterally, be careful to stay superficial to avoid damage to the caudal margin of the medial crura . Use a no. 15 blade to make the columellar exten sion of the marginal incision on both sides of the columella, 1 to 2 mm behind the leading edge of the columell a (Fig. 12). This incision is made along the caudal margin of the medial and intermediate crura. By minimi zing the dis section over the medial crus, damage to this cartilage can be avoided.

Beginning laterally, make a light incision throug h vestibu lar skin 1 to 2 mm cauda l to the caudal margin of the late ral crura . Follow the caudal margin of the lateral crura as the inci sion is extended medi ally. (The dissector has already mad e the marginal incision on one side; here simpl y make a marginal incision on the other side .)
Define the Columellar Flap By using angled Con verse scissors, or another suitable dissecti ng scisso rs, elevate the thin vestib ular skin of the flap that covers the medial crura. Insert the scissors beneath the col umellar extension of the marg inal incision and dissect med ially in the correct plane of dis section, below the musculoaponeurotic layer (Fig. 13). The scissors should then pass super ficia l to the caudal margin of the ipsilateral and then contralateral medial crus (Fig . 14). Guide the scissors through the oppos ing colume llar extension of the marg inal incision (Fig . 15). During this dissection, take special care to avoid dama ging the flap or the caudal margin of the medial crura . Use the scissors to spread the tissues in the plane of dissection (Fig. 16). If not positioned properly, the dissector may cut through the cauda l margin of the media l crura. To avoid this, the dissector must remain caudal to the medial crura and dissects very carefully.
Flap Elevation Use the Con verse scissors to compl ete the midcolumellar incis ion without beve ling the incisio n or damaging the medial crura (Fig. 17). Take specia l care to avoi d beveling this in cisio n. Use a narrow do uble-prong hook to retract the flap. Th e paired columellar arte ries may be see n, and typic ally must be cauterized with bipolar cautery .

Three-Point Countertraction
•
To elev ate the skin/soft-tissue enve lope over the nasal tip, (a) place a wide doubl e-p hook along the margin of the nostril rim caudal to the latera l crus, (b) place a small dou prong hook on the columellar flap , and (c) place a small double-prong hook on the vest lar skin side of the intermediate crus (Fig . 18). Then use Converse scissors to dissec columellar flap fro m the caudal margin of the medial and intermed iate crus, as the c tertraction acts to expose the areolar tissue plane. The scissors are used to expose the da l aspect of the lateral crus as well. Then the dissection advances cephalica lly over the face of the lateral crus . As the dissec tion continues along the surface of the lateral crus, tissue is eleva ted, leaving only perichondrium on the cartilage . As dissection proceeds erally along the lateral crus, cut the vestibular skin along the caudal mar gin of the la crus, thereb y completing the marginal incision. Make sma ll, calibrated cuts under direc sion to avoid inadvertently cuttin g throu gh the lateral crus . Limit dissection of the la crus to the areolar tissue plane deep to the muscle. A cotton-tip applicator can be use comp lete the dissection of the lateral crus once the deep aero lar tissue plane has been i tified. A portio n of the dissection on the opp osite side was performed with the cartilage livery approac h; nevertheless, repeat these maneu vers on the oppos ite side to complet eva tion of the skin/soft-tissue envelope over the nasa l tip. [An altern ative approach to this dissectio n is to begin dissection thro ugh the margina cisio ns (retrograde dissection) (12).] In this approach, identify the proper tissue plane , eleva te the skin/soft-tissue envelope off the lateral crus . Then proceed med ially with s sor dissection toward the do mes and intermedia te crura. This maneuver is performed b era lly to achieve elevation of the skin/soft-tissue enve lope. This retrograde dis section is helpful if the surgeon is hav ing difficulty followi ng the dal margin of the inte rmediate and lateral crus. Th is is not unusual in cases in which t is buckling of the interme diate crus or domes. Retrograde dissection genera lly is not the proac h of choice for seco ndary rhinoplasty, as the lateral crura may have been exci se previously dissecte d.] [Examine the latera l crura on the side of a transcartilaginous incision and cephalic t Eval uate the excisio n of cephalic cartil age.

Elevation of Periosteum/Exposure of Bony Vault
Under direct vision by using an Aufricht or Converse retractor, use a Joseph peri elevator or other appropriate instrument to cut through the periosteum 2 mm cephala parallel to the caudal margin of the nasal bones (Fig . 22) . Alternatively, palpate the junction between the nasal bone and ULCs with the Jose evator beneath the skin/soft-tissue envelope by gently allowing the Joseph to "fall" o nasal bone onto the ULCs as it is withdrawn. The Joseph elevator can then be seated above this junction with certainty, and the periosteum incised. Elevate the periosteu the bony nasal vault up to the nasion. Then elevate in the subperiosteal plane over the dorsum toward the midline and laterally (Fig. 23). Execute these maneuvers bilat (Fig. 24) .

PEARLS
• If the surgeon plans to place a dorsal graft or radix graft, a precise pocket can made over the upper dorsum and/or radix. This will allow the surgeon to place graft into a precise pocket and minimize the chance of graft migration. • If the surgeon plans to place an alar batten graft, the lateral extent of the dissect should be minimized. . • During the extermil rhinoplasty approach, elevation of the skin/soft-tissue en lope from the underlying supportive structures of the nose results in disruption the minor tip-support mechanism provided by the attachment of the skin/softsue envelope to the lower lateral cartilages. To help offset this loss oftip supp a columellar strut cartilage graft can be 'sutured in a pocket between the med crura . Such a strut is used to support the medial crura to preserve tip projection not necessarily to increase tip projection (Appendix F). • The columellar extension of the marginal incision should beplaced only 1 to 2 m behind the face of the columella to minimize dissection of vestibular skin and avoid damage to the caudal margin of the medial crura, • When advancing the converse scissors across the .columella to the oppos med marginal incision, special care should be taken to remain caudal to crura . • Dissect in the tissue plane just above the perichondrium. Avoid violating the m cle layer. . • DUling dissection; follow the caudal margin ofthe lower lateralcartilages. If caudal margin is lost sight of, move laterally to pick up the lateral crus, and diss retrograde to avoid cutting across a buckled intermediate crus or deformed dom • Precise closure of the midcolurnellar incision, with meticulous alignment of skin edges, is critical to prevent an unsightly scar. Principles ofskin-edge evers and tension-free closure will also help prevent a visible scar. Vertical mattre suture closure aids in skin-edge eversion. ' . ' .

6 Removal of Bony-Cartilaginous Hump
In this exe rcise, the car tilaginous and bony hum p are removed en bloc. Be conservative! Plan to take a small amount of the hump off at first and thereby avoid incising the mu coperichondrium, which provide s important support. Later, after the bony-cartilaginous hump has been removed, be prepared to make multiple fine adj ustments of both the septum and dorsal margins of the upper lateral cartilages. When lowering the dorsal septum, keep in mind the imp ortance of allowing for the thicker skin over the lower one third of the nose. Also, recogniz e that inadequate resection at the supratip may result in a polly-beak defor mity. (Appendix G) [Note: The dissector may wish to incise the skin/soft-tissue envelope down the midline either now or subsequent to this chapter. The hump excision may be done first, and then split the skin to exami ne the result and allow easy exposure for subsequent maneuvers. If the dissector intends to augment the dorsum with a cartilage graft, this may be done first, and then split the skin for easy exposure during the remaining dissection. The skin in the midlin e can be sutured back together as desired at any time.] Expose the cartilaginous dorsum with a Conv erse retractor, and use a no. 15 blade to in cise lightl y any remaining soft tissue overlying the cartilaginous dorsum. Reflect this tis sue laterally on both sides. Next, beginn ing at the osseocartilaginous junction and pro ceeding caudally, incise the cartilag inous dorsum at the planned level of initial excision (Figs. 1 and 2). Try to keep this incision eve n on both sides, but remember that there will be additio nal "fine-tuning" modifications after initial hump excision. Unde r dire ct vision, place an osteotome agai nst the bon y hump at the osseocartilaginous junction (Fig. 3). Use the incised but attac hed cartilagino us dorsum to help seat the os teotome at this locat ion. With a gentle, controlled two-tap technique, incise the bony hump with the osteotome (Fig. 4). Take care not to overresect the bon y hump , as the osteotome will tend to cut deepe r into the bone . Remove the hump with a hemo stat or similar instru ment , and examine its features (1,2). When exec uting hump excision , preserve the underlying nasal mucoperichondrium. The nasal mucoperi chondr ium provides support to the upper lateral cartilages and help s de crea se the risk of inferomedi al collapse of the upper lateral cartilages after hump excision (Fig. 5).

the nasal bones can lead to an "inverted V deformity," in which the upper lateral c collapse inferomedially, and the caudal edges of the nasal bones are visible in broa creating an unacceptable appearance.] (3,4 ) (Appendix G) Now make additional fine-tuning modifications to the cartilaginous dorsum as in Examination of the excised hump may guide any additional excision. Trim the (dorsal) margins of the upper lateral cartilages such that they lie on a level with or low that of the trimmed border of the septum. Additional modification of the bony also may be required. An "open roof" may be created by hump removal. The bony margin s should smoothed with a rasp by using few but firm strokes (Fig. 6). Any bony fragments s removed, making sure that all obvious particles are removed from under the s tissue envelope. An alternative to the manual rasp is a powered reciprocating rasp or sheathed bu 7 and 8) (5). These instruments can be used wherever a manual rasp would be used , less soft-tissue trauma. The site to be treated can be directly visualized. The pow struments are especially useful to smooth the bony marg ins of the open roof. They useful to correct isolated bony irregularities that may be encountered, for example ond ary rhinoplasty. It appears that a more reproducible result can be obtained with incidence of visible or palpable bony dorsal irregularities. After rasping or burrin particles should be irrigated from the surgical site .

[Note: This is one approach to hump excision. Another approach is described here some cases, the surgeon may wish first to separate the upper lateral cartilages from the d sal septum. This is accomplished in the submucoperichondrial plane and can be readily complished through the hemitransfixion incision or external rhinoplasty approach (Fig. Then rather tban excising the entire cartilaginou s hump , only a strip of dorsal septum is cised. The remainder of the hump excision proceeds as described earlier; tbe upper late cartilages are then shaved down individually so that they are at the same level as the dor septum.] This method is good for excision of large dorsal humps where preservati on of m cosal cont inuity may be otherwi se difficult.

7 Osteotomies
MEDIAL OSTEOTOMIES To perform medial osteotomies, insert the osteotome at the jun ction between the nasal bone and sep tum. With the two-tap technique, advance the cutting edge cephalad and fade laterally as the frontal bone is reached (Fig. 1). Control the sharp leading edge of the chisel, as it moves under the skin, with the forefinger of the nondominant hand . Thi s fading me dial osteotomy avoids the thick frontal bone. Medial osteotomies are usually not necessary in cases in which large dorsal humps are excised, leaving an open-roof deformity .
LATERAL OSTEOTOMIES AND INFRACTURE [Note : The dissector may wish to mark the site of the propo sed osteot omy on the skin be fore proceedin g. Perform the lateral osteotomy on one side, and then reflec t the skin/soft tissue envelope laterally to exa mine it. Is it in proper position? Is the periosteum intact, or has it been violated? Is the mucoperio steum intact? After assessing the first lateral osteotomy, the skin of the oppo site side may be reflected before the osteotomy. Th is will allow observation of the osteotom y unde r direct vision.] T he lateral osteotomi es run from the most lateral point of the pyriform aperture to a point medial to the inner ca nthus of the eye, taking a high to low to high path . In practice, this means a starting point 3 mm to 4 mm abo ve the base of the pyriform aperture and adja cent to the head of the inferior turbinate. The high-to-low lateral osteotomy preserves a small triangle of bone at the base of the pyriform aperture (Fig . 2). Use a 2-mm (unguarded ) or 3-mm (guarded or unguarded) curved or flat osteotom e. Use a guarded or unguarded os teotome based on preference. Make a small incision near the base of the pyriform apertur e. Althou gh it is not essen tial, many surgeons create a short subperiosteal tunnel along the path of the proposed lat eral osteotomy . Seat the osteotome on the bone 3 mm to 4 mm above the base of the pyri form aperture, and use a gentle two-tap technique to advance the osteotome gradually. Angle the osteotome in a posterior and cephalic direction initially, and then adjust the os teotome so that the cutting edge travels toward a point medi al to the inner canthus of the eye. Thi s creates the typical high-to-low-to-high lateral osteotomy . Control the cutting edge by palpation with the thumb or fingers of the nondominant hand as the osteotome travels toward the inner canthus. When the osteotome approaches the level of the inner canthus,

rotate the osteotome clockwise on the patient' s right side and counterclockwise on th side. This will normally fracture the nasal bone inward creating a controlled backfrac It may be necessary to complete the fracture with thumb pressure . INTERMEDIATE OSTEOTOMIES
An osteotomy between the medial and lateral osteotomies is occasionally indicated. cific indicat ions include the abnormally contoured nasal bone that is either excessively vex or conc ave. Intermediate osteotomies are most effective for decreasing the curvatu an excessively convex nasal bone. The intermediate osteotomy allows recontouring o nasal bone for correction of the severely deviated bony vault. This osteotomy is perfo before the lateral osteotomy. A 2-mm transcutaneous osteotomy performed midway u nasal bone is typically used to complete the intermediate osteotomy .

• Medial osteotomies are performed to control the backfracture of the nasal bon after lateral osteotomies. If a large dorsal-hump removal was performed, leavin an open roof, it may not be necessary to perform medial osteotomies. • High-to-low-to-high lateral osteotomies are performed to leave a small triangle bone at the base of the pyriform aperture and. prevent medialization of the inferi turbinate. " • The dorsal nasal septum at the level of the bony vault must be midline to allo symmetric medialization of the nasal bones; If there is difficulty medializing t nasal bones , a blade handle can be used to shift the bony septum to the midlin with the nasal bones : .

8 Spreader Grafts
Spreader grafts may be placed endonasally or via the external rhinoplasty approach. If en donasal placement of spreader grafts is done in this dissection, undertake this before hump reduction and osteotomies. Through a small (5-mm) mucosal incision near the anterior septal angle, develop a pre cise subperichondrial pocket along the length of the cartilaginous dorsum near the junction of the dorsal septum and upper lateral cartilage (Fig. 1). A Cottle or Freer elevator can be used to elevate the subperichondrial tunnels. Special care must be taken to get into the sub perichondrial plane; otherwise, the mucosa may tear. Additionally, avoid pushing the ele vator through the septum to the other side. Fashion rectangular spreader grafts that extend from the osseocartilaginous junction to the internal nasal valve where the upper lateral car tilage meets the dorsal septum. Appropriate thickness can be determined to achieve the de sired functional effect without causing excessive widening, usually I mm to 3 mm in thick ness. Experience is required to develop reliable surgical judgment regarding the appropriate width and length of spreader grafts. Insert the grafts into the precise subperi chondrial tunnels, taking great care to preserve the mucosa (see Fig. 1). [Note: After placing endonasal spreader grafts, return to Chapter 6 and perform hump excision and then osteotomies. To exam.ine the precise pocket that was made before hump removal, separate the upper lateral cartilage from the septum, as described below and il lustrated in Fig. 2.] Division of the upper lateral cartilages from their attachment to the dorsal septum is un dertaken in the submucoperichondrial plane (see Fig. 2). This may be done before hump excision, or in cases in which no hump excision is necessary. Alternatively, this maneuver may be undertaken after hump excision. Again, great care should be taken to preserve an intact mucoperichondrium. The accompanying figures (Figs. 2 through 6) illustrate placement of spreader grafts through the external rhinoplasty approach. At this point, the dissector should have under taken hump reduction and osteotomies. (If hump removal has not been completed, return to Chapter 6). Spreader grafts are placed into pockets between upper lateral cartilage and dorsal septum (Figs. 3 and 4). A typical graft extends from the osseocartilaginous junction to the anterior septal angle. The spreader grafts are secured with absorbable suture [we rec ommend 5-0 polydioxanone suture (PDS), Monacryl, or other similar suture]. The spreader

Alterna tively (and commo nly), simply engage all structures (upper lateral cartilage-to-spreader graft-to septum-to-spreader graft-to-upper lateral cartil age) with a single mattress suture (Fig. 6). An additional horizontal mattr ess suture may be necessary to secure the spreader grafts and upper lateral cartilages in position . A needle of adequ ate size (such as a PS-2) facilit ates en gaging all structures in a single pass (Fig. 6). Do not cinch down the mattress sutures too tightly or inferiorly, or else the upper lateral cartila ges may actually be forced mediall y.
SPREADER GRAFTS In the absence of other causes of nasal obstruction , the nasal valve and nasal valve area constitute the flow -limiting seg ment of the nose. Th e nasal valve is bounded by the caudal border of the upper lateral cartilage and the nasal septum, which join at an angle of 9 de grees to 15 degree s in the norm al Caucasian nose (Fig. 7). A valve fulfills the definition of a movable structure that regulates the flow of gas or fluid. The nasal valve area includes the cross-sectional area described by the nasal valve and is affected by the in ferior turbinate, the caudal septum, and the tissues surrounding the pyriform aperture (Fig. 7). The nasal valve area is con sidered to be the location of the least cross-s ectional area in the nose and is belie ved to regulate significantly both nasal airflow and resistance and the velocity and shape of the air stream. The nasal valve area is the major flow -resisti ve segment of the nasal airway (I ). An overnarrow nose in the middle third, whether congenital or (more commonly) the consequence of previous surgery or trauma, requires cartilage graft augmentation to im prove the airway and restore aesthetic balance. Examinati on may reveal an overnarrow an

gle at the nasal valve area, medi al coll apse of the valve on even modes t inspi ration, or col lapse of the upper lateral cartilage against the septal wall , effecti vely compromising the air way. Spreader graft s act as spacers between the upper lateral cartila ge and septum, cor recting an overnarrow middl e vault and internal nasal valv e or preventing excessive narrow ing in the high-risk patient (2-10). A submucoperichondrial tunnel on one or both sides of the dorsal aspect of the septum may be prep ared by elev ating the mucoperichondrium bridging the upper lateral cartilages to the septum. Thi s dissection provides a space to be filled by a cartilage graft insinuated into the pocket, lateralizing the upper lateral cartil age(s), improving the airw ay and effec tivel y widenin g, when indic ated , the appearance of the middle third of the nose. In our ex perience, spreader grafts are mo re effective when the fibrous connections between the dor sal septum and upper lateral cartilage are left intact. Applicati on of the spreader grafts creates a cantilever effect and aids in lateralizing the upper lateral cartilage to provide max imal airway improvement. Whereas spreader grafts may be comfortably carried out through traditional endonasa techniques (2), in more complex recon structi ons, particularly complicated by multiple ab norm alities, an external rhinopl asty approach may facilitate accurate dissection and graf suture fixation (6) . When the T-shaped configuration (horizontal exten sion) of the nasal septum is resected with dorsal-hump remov al, narrowing of the middle nasal vault may be problematic in the high-ri sk patient. Identifying the high -risk patient during initial preoperative analy sis is es sential to the prevention of excessi ve narrowing of the middle nasal vault with internal nasal valve collapse. An anatomic variant referred to as the "narrow-nose syndrome" has been described (2,6). Short nasal bones, long weak upper lateral cartilages, thin skin, and a narrow projecting nose pred ispose to middle vault collapse . A large en bloc hump re moval should be avoided, as the T-sh aped horizontal support of the nasal septum is elimi nated and the intran asal mucosa (which provides support to the upper lateral cartilage) is at risk of injury . Regardles s of the approach to the middle vault, keepin g the intrana sal mu cosa intact with execution of profile alignment (dorsal-hump removal) helps maintain im portant support of the upper lateral cartilages (see Chapter 6, Fig. 5). This can be achieved by dissectin g submucosal tunnels and freeing the upper lateral cartilages from the septum before cartil aginou s hump remov al. Alternatively, conservative hump excision followed by millimeter-by-mill imeter shaving of the upper later als under direct vision preserve s the in tranasal muco sa. Coll apse of the middle nasal vault may highlight the caudal edges of the nasal bones to produce the characteristic "inverted V" deformity (Appendix G) . When the dorsal hump has been taken down and the upper lateral cart ilages appear desta bilized , such as in the high-risk patient, suturing the upper lateral cartilages back to the sep tum can be helpful to prevent middle nasal vault collapse.

pre ser ve an ade quate nasal valve. An external rhinoplasty approach may faci litate accurate graft-suture fixa tion in this setting. These precautionary maneuvers are not necessary in all cases but may prevent problems in the high-risk pati en t (6) . Commo nly performed surg ical maneuvers can result in loss of support to the midd le vault. Cephalic him (volume redu ction) of the lateral crura disrupts the scro ll (rec urvature) and frees the ca uda l margi n of the upper lateral cart ilage . Lateral osteotomies may further medi alize the upper lateral cart ilages . T he upper lateral car tilages can fall toward the narrowed dorsal sept al edge, producing narr owin g of the middl e vault and internal valv ular collapse. In the majority of pa tients, the combi nation of these m aneu vers will not result in a pro blem; however, in high-ri sk patients (narrow-nose syndrome), this combination of maneu vers may co ntri bute to excessive narr owin g of the middle vault with internal valve co llapse. W hen spreader grafts are used, appropria te spreader-graft thickn ess will achieve the de sired fun ction al effect wi tho ut causi ng overwide ning . Great care sho uld be taken to avoid overwide ning if poss ible. Experi ence is required to deve lop relia ble surg ical judgment re garding the appropriate width and length of spreade r grafts. Careful palp ation of both up per lateral cartilages can aid in ver ifying symmetry of the middle nasal vaults. Spreader grafts are usually 1 mm to 3 mm in thickness . It is ge nerally better to use thin ner spreader grafts because if the midd le vault is too wide, rev isio n surgery wi ll be nece s sary. After spreader grafts are secured in pos ition via the externa l app roach , or if they are placed endo nasa lly after dissection of the soft-tissue enve lope , the middl e-vaul t width can be assessed by inspect ion and palpa tion . T he middle vault sho uld be no wider than the bony vault and nan-ower tha n the nasal tip. If excessive width or asymm etry is noted, the grafts should be rep osition ed or narrowed, O ver time, this area of the nose tend s to nalTOW as edema resolv es and sca r contracture pulls the upper lateral cartilages mediall y. Asy mme try of the middle nasal vau lt may at times be addressed with the placement of a unilateral spreader gra ft, or alterna tive ly, with the placement of sprea der grafts of unequ al thickn ess (Fig . 8) ( 10). In most cases, we prefer to use bilateral spreader grafts to splint de viations of the dorsal sep tum and preven t worsening of the dorsal septal devia tion. A variety of other maneuvers are at the surgeon ' s disposal in addressing the middle nasal vault.

PEARLS
• If there is difficulty in spreader-graft placement by using an external approach check the expo sure. A common mistake is a failure to carry the marginal incision and dissection over the lateral crura laterally enough, limiting exposure. Extend ing this incision and dissection appropriately will improve exposure of the middl nasal vault and greatly facilitate spreader-graft placement. • Double check middle-vault width and symmetry after applying spreader grafts Careful palpation will allow preci se assessment of middle-vault width. • Spreader grafts applied into preci se submucosal tunnels iritroduce bulk under the intact connection between the upper lateral cartilage and dorsal septum. Th spreader graft creates a cantilever effect and effectively .lateralizes the collapsed upper later al cartil age. • When securing spreader graft s via suture fixation, gently stretch the upper latera cartilage toward the anterior septal angle to ensure that they are not buckled. Th suture will place gentle traction on the upper lateral cartilages to prevent buckling After completing suture fixation, inspect the upper lateral cartilages to be sure tha they are not buckled (6) . . . • In considering nasal ob stru ction , co mplete evaluation is critical. Cau ses of nasa obstruction include allergic rhinitis, chronic sinusitis; rhinitis med icamentosa nasal pol yps, deviated septum, internal and external nasal-valve collapse, and oth ers. One commonly overlooked cause of nasal obstruction is a concha bullosa, o aerated middl e turbinate (Fig. 9), which can be most easily recognized on nasal en dos~opy or coronal computed tomography scan. .

9 Surgery of the Nasal Tip
EXERCISES (Appendix F) Placement of Columellar Strut The placement of a rectangul ar cartil age strut between the medial crura can improve tip support and augment tip projection. A columellar strut also can be used to correct buckled medi al or intermediate crura or to increase columellar show. The strut may be placed by us ing the externa l approac h or into a precise pocket via the endonasal approach.
Placement of Columellar Strut via an External Rhinoplasty Approach The area between the medial crura is dissected to create a pocket to place the strut. The rect angular cartilage strut typically measures 8 mm to 12 rnm in length, 3 mm to 4 mm in width, and 1 mm to 2 mm in thickness. Th e strut is most typically fashioned from harvested septal cart ilage, but also, when necessary, from auricul ar cart ilage, and at times from rib cartilage. The strut is positioned so that it sits above (without extending to) the nasal spine (Fig. 1). It is preferable to leave a small soft-tissue pad between the strut and the nasal spine. The strut should not extend above the intermediate crura . It is secured to the medial crura with several absorbable mattress sutures (e.g., 4-0 plain gut, Keith needle) placed through the vestibular skin. Asymme tries of the lower lateral cartilage (LLC) may be improved with placement of the strut (Fig. 2). Asymmetry of the tip may be created if the medial crura are asymmet rically sutured to the strut (Fig. 3), or if an overlong strut extending beyond the nasal spine shifts to the side of the nasal spine, thereby causing a deviated nasal tip (Fig. 3) ( 1,2).

Identify the scroll region, the cephalic border of the LLC (Fig. 8). Excise the cephalic por tion of the LLC by making an incision parallel to the caudal margin with the 15 blade and then peeling off the cephalic portion , leaving the vestibular skin behind. The line of inci sion parallel s the caudal margin of the LLC. Leave at least 7 mm to 9 mm of intact carti lage . This preserves an intact strip of cartilage from the feet of the medial crura to the most lateral part of the lateral crus. This will produce conservative narrowing of the nasal tip.

Now apply domal/transdornal suture s as outlined.
Place Individual Horizontal Mattress Domal Sutures
For domal sutures (Fig . 9), a mattres s suture of 5-0 polydiox anone suture (PDS) or oth appropriate suture is passed through each dome, and the knot of each mattre ss suture is ti between the domes. As the sutures are secured, narrowing of the tip is accomplished. A interdomal suture sets the width between the domes. If stiff nasal-tip cartilages are e countered, the surgeon should use 5-0 clear nylon instead of PDS (4-6).
Place Single Transdomal Suture
Alternatively, a single transdomal suture that traver ses both domes may be placed, in li of two individual domal sutures and an interdomal suture (Fig . 10) (1-3). The caudal pa should be slightly longer than the cephalic pass of the mattress suture . When the mattre suture is placed in this fashion, the caudal edge will tend to lead the cephalic edge as t suture is tightened. This creates a more favorable tip-supratip relation . If the cephalic ed leads the caudal edge of the lateral crus despite proper placement of the domal suture, small cephalic wedge of the cartilage may be excised and the edges sutured, which repos tions the cephalic edge lower in relation to the caudal edge (Fig. 11).

Lateral crural steal (Fig. 12) is an effective method for increasing tip projection and rota tion (7). When the horizontal mattress domal sutures take a larger bite of lateral cru s, a por tion of the lateral crus is shift ed mediall y. Th e " medial crura]" leg of the tripod is length ened , where as the "lateral crural" legs of the tripod are shortened (see Appendices A and F); the result is increased proj ection and rotation . Tip refinement also is achiev ed, as with a standard dom al suture.
Further Refinement with Dome Division with Intact Vestibular Skin and Suture Reconstitution We rarely divide the domes, but when this technique is performed, it is usually in the thick skinned patient. In most cases, we use some form of dome-binding suture to change tip con tour (8). Rem ove the transdomal sutu res to perform this maneu ver. Dividing the dome by verti cal incision allows further narrowing of the nasal lobule. Proje ction also can be alte red by removal of a superiorly based triangle of cartilage lateral or medi al to the vertic al incision. By excising a larger amount of car tilage along the cephalic margin of the later al crus, the cephalic dom e can be positioned below the caud al dome (Fig . ]3 ).

We try to avoid dome vision in patients with thin skin.

Tip Graft
Sutured in place, shield-shaped tip grafts typically are used to increase tip projection and change tip contour (1,2). They also can be used to camouflage tip asymmetries. Tip grafts should be avoided in patients with thin skin. Carve a shield-shaped tip graft from the harvested septal cartilage. The width generally varies from 8 mm to 12 mrn at the leading edge . The length varies from 8 mm to 15 mm and thickness typically varies from I mm to 3 mm (Fig . 16). The graft is thicker at the lead ing edge and thinner at the base. One may consider cutting the graft larger at the leading edge to allow in situ carving once the graft is secured in position. The graft is sutured to the caudal margins of the medial/intermediate crura that have been stabilized by the sutured in-place columellar strut. An excessively thick tip graft will increase fullness in the infratip lobule . Secure the tip graft with 6-0 PDS or Monacryl sutures (Fig. 17). Four to six sutures are usually applied. Place the lower sutures first.

When placing a tip graft in a patient whose dome s have been divided (and suture recon stituted ), apply the tip graft so that it camoufl ages the caudal aspect of the cut dom es (Fig. 18), decreasing the risk that this point will be palpable or visible after surgery.
Figure 18. If a tip graft is applied in a patient with divided domes, the caudal aspect of the cut domes should be hidden behind the tip graft to decrease the risk of a palpable or visible point after surgery.
Cap or Buttress Graft
Typically, a tip graft should be projected 1 mm to 2 mm above the existing domes. In pa tient s with thick skin and an underpr ojected tip, a longer tip graft can be projected 2 mm t 4 mm above the existing domes. In these and other appropriate cases, a cap or buttress graf placed behind the leadin g edge of the tip graft may be useful to support the graft (particu larly softer, pliable auricul ar cartilage tip graft s) and to prevent excessive cephalic rotation of the graft under the tension of closure of the skin/soft-tissue envelope. Buttre ss grafts ar sutured to the tip graft and both domes by using 6-0 PDS or Monacryl suture (Fig. 19). The buttress grafts should creat e a smooth transition from the edge of the tip graft to the cauda margin of the lateral crura (2).

Alar Batten Graft The external nasal valve is composed of the cutaneous and skeletal support of the mobile alar side-wall. Overaggressive resection of the lateral crura during rhinoplasty and the sub sequent postop erati ve soft-tissue contraction may lead to internal and/or external nasal valve compromise. Ceph alic positioning of the lateral crura also will leave suboptimal structural support in the mobile alar side-wall (external valve collapse). Alar batten grafts , typically of curved septal or auricul ar cartilage, placed to support the alar rim, can correct internal or external nasal-valve coll apse (Fig. 20) (l0-12). Create a precise pocket for an alar batten graft. The graft is typically placed caudal to the lateral crura at the point of maximal lateral nasal wall collapse. Fashion a graft from har vested auricular or septal cartilage, and insert it into the precise pocket. The pocket is sub cutaneous and is placed at the point of maximal supr aalar collapse. Auricular cartilage is preferred becau se of the curvature of the cartilage. The convex side of the graft is oriented laterall y to correct the supraalar pinching. If this pock et is too superficial, the graft may be palpable or visible . When placed via an external rhinoplasty approach, secure the graft with a suture applied medially from the graft to adjacent soft tissue or lateral crus.

crura. These grafts are shaped like lateral crura and measure approximately 5 mm in ver cal height. Auricular cartilage has the ideal curvature for lateral crural grafts. The grafts a sutured to the vestibular skin and medial or intermediate crura . Care is taken so the caud margins of the grafts are placed symmetrically; otherwise, there may be asymmetry of t alar rims. Grafts that are too large or curved may create a bulbous tip (2) (Fig. 21) .

PEARLS
Complete Strip • Although many surgeons perform cephalic trim of the lateral crura as a routine ma neuver during rhinoplasty, some patients have flat or concave lateral crura that do not contribute to tip bulbosity. Many of these patients do not need to undergo ' cephalic trim of the lateral crura. Cephalic trim should be performed when there is fullness (bulbosity) in the supratip or supraalar region due to protrusion ofthe cephalic margin of the lateral crura. : • The surgeon should leave 7 mm to 9 mm of lateral crus. This determination is made on a patient-to-patient basis. The strength of the lateral crura and alar side walls should be considered. With strong cartilages, more cartilage can be excised, and with weak cartilages, more cartilage should be preserved. . .. • Complete strip is illustrated here via the external rhinoplasty approach but was il- '. lustrated earlier in this text via the cartilage-splitting approach (Chapter 5, Figs. 1-3). In a cartilage-splitting approach, the attachments of the lateral crura to the skin/soft-tissue envelope are undisturbed, and a complete strip of 6 mm to 8 mm should be preserved. Cephalic resection of lateral crus may also be accomplished ' via the retrograde dissection approach and via the delivery approach; • Minimize lateral resection of the cephalic margin of the lateral crura. Change iri tip contour is primarily effected by niedial excision, and .lateral excision can con tribute to valve collapse and supraalar pinching, I' • Thin skin, strong cartilages, and bifidity is a cornmon triad that should be recog nized. These patients are at higher risk for bossa formation if excessive cartilage is excised from the cephalic margin of the lateral crura (Appendix G). . .
.PEARLS, continued Transdomal Sutures . • Tran sdomal suture placement can create excessive fullness in the infratip lobule.
The infratip lobule should be assessed after transdomal suture placement. Addi
tionally , the lateral aspect of the lateral crura may medialize into the airway with
. placement of a transdomal suture. If this occurs, it may be necessary to apply lat- . . eral .crural strut grafts to straighten the lateral crura . On rare occasions, the lateral- ; most aspects of the lateral crura may need to be trimmed. . • .Separate dome binding sutures are better able to correct asymmetric domes . .. Tip Grafts • Before closure, all edges of the tip graft should be rounded off to prevent visibility
ofthe edges of the graft.
• Excessively stiff tip grafts should be crosshatched on the caudal surface to allow
cephalic bending and a good double break.
o Surgeons tend to make shield grafts too narrow. Most grafts should be approxi
. matelyB mm to 10 mm in width at the leading edge : In male patients, the tip grafts
are generally wider, and typically measure 10 mm to 12 mm in width at the leading edge : · .. • Most cadaver specimens have thin, atrophic skin, so the tip graft will tend to be more
· . noticeable. Indeed, we try to avoid the use of tip grafts in patients with thin skin.
• Tip grafts are ideal for camouflaging subtle tip asymmetries.
Alar Batten Grafts . • Alar batten grafts may be placed via anextemal rhinoplasty approach or into apre cise pocket made through an endonasal incision. This graft is nonanatomic and is typically placed caudal to the lateral crura where there is maximal collapse of the lateral nasal wall and supraalar pinching. .• If alar batten grafts are placed too far cephalic, excessive fullness over the middle vault will be noted. • Patients should be told that there will be temporary fullness in the area of the graft.
This fullness will typically decrease over a 2- to 3-month period. .
. o For maximal support, the alar batten graft should extend over.the bone of the pyri form aperture. .

10 Alar Base Resection
Follow the accompanying figures and text to perform alar base resections (1,2). Th e site of incisions and the amount, deg ree, and geometry of alar red uctions depend on a host of anatom ic variations predetermined before and durin g surgery . Alth ough the sur geo n's aesthe tic j udgment will ultimately determine the site and degree of resection, a more precise surgical approach may be determined if several anat omic guidelines are asses sed and inte grated . Co nservatism is mand atory to avoid overreductio n and asy mmetry, condi tion s that are difficult to correct satisfactorily. As the need for reductio n increases, both the incision and exc ision become more ex ten sive. Alar redu ction is a co mprom ise operation, in which gre ater reductions exa ct the penalty of a larger scar. The surgeon must balance this compromi se with experienced aes thetic j udgment and prov en scar-camo uflage techniques. Skin sutures placed acro ss the alar-facial junction often lead to permanent suture marks. Effe ctive camouflage at the alar- facial junction may be facilitated by positioning incisions I mm to 2 mm above the alar- facia l junction. Skin clo sure can be pe rformed with a cyanoa crylate adhes ive (oc tyl-2 -cyanoacrylate, Dermabond ; Ethicon , Somerville, NJ , U.S.A.).
INTERNAL NOSTRIL FLOOR REDUCTION
In patients requiring minimal alar redu ction, ex cision of a wed ge of epithelium and soft tissue from the nostril flo or only (Fig. I) will slightly reduce the alar flare by reducing the dimension of the internal (medial) border. Althou gh the outward curve of the ala is altered, no medial repo sitioning of the alar-facial junction is effected . The scar is effectively hid den within the nostril floor if the nostril sill is not violated. At times , the sha pe of the nos tril sill will determine whether this approach is appropriate. Subtle, conservative , but ef fective improvements are possible with this approach . Th e dimension of the lateral alar border remains unchanged.

WEDGE EXCISION OF NOSTRIL FLOOR AND SILL
Further reduction of alar flare is accompli shed by carry ing the incision acro ss the sill in the alar- facial jun ction I mm to 2 mm above the alar-facial crease. Reduction of flare well as slight reduction of the alar bulk is effected (Fig. 2).
ALAR WEDGE EXCISION
If the alar development is excessive and bulbous , excision of a wedge of ala at t alar-facial junction 1 mm to 2 mm above the alar-facial crease will reduce the overall bul iness of the alar anatomy (Fig. 3). Som e medi al repo sitioning of the alae may be effecte with this maneuv er. Reduction of the overall length of the alar sidewalls occurs when ge erou s wedges are excised, ideal in the reduction of the alar flare created when correctin the overprojecting tip. SLIDING ALAR FLAP
More substantial alar reduction with medi al repositioning is effected with a generous i cision above the alar- fac ial jun ction with variou s degree s of alar excision (Fig. 4). Redu tion of th e volume, curve, and flare of both the internal and external alar margins will r sult from this procedure, the extent of each dependent on the angulation of the alar incisio A backcut placed 2 mm above the alar-facial j unction allows the alar flap to slide mediall narr owing the alar base signifi cantly.

PEARLS . ' When performing alar base reduction, the surgeon should err onundercorrecting . the deforrnityto prevent resection of excessive tissue. Once too much tissue is ex cised, it is very difficult to correct ; be particularly conservative in male patients . • Internal alar base excision can significantly decrease the internal diameter of the nostril and should be performed in a conservative manrier. When performed, usu- . ally <2 mm of tissue is removed. • Ifan incision is made on the lateral surface of the ala, the incision should be made above the alar crease to minimize scarring. A cyanoacrylate adhesive (Der maborid; Ethicon, Somerville, NJ, U.S.A.) can be used to close the lateral alar in cision. • In the incision, the skin edges can be favorably beveled to maximize skin-edge eversion and avoid a depressed scar. ,

11 Other Maneuvers
PLUMPING GRAFTS Plumpin g grafts may be used to open up an acute nasolabial angle, improve a retracted columella, and support a deficient nasal base. Dissect a midcolumellar precise pocket to ju st above the nasal spine. Place multiple small pieces of cartilage (I rom to 2 mm), har vested from the septum or ear, in the pocket. These grafts will augment the deficient area (Fig. 1) (1,2). Plumping grafts placed below the medial crural footplates will increase sup port of the nasal base (Appendix F)

CAUDAL EXTENSION GRAFTS
Caudal extension grafts have been described for use in correcting a retracted columell overrotated tip, short nose, or to increase tip support and projection (3) (Appendix F). Th graft is sutured to the caud al margin of the nasal septu m and is secured between the medi crura in the midlin e with 5-0 buried polydioxanone suture (PDS ) (Fig. 2). When suturin the caudal extension graft to the caudal septum, the caudal margin of the graft must be the precise midline. Devi ation off the midlin e will result in a deviation of the nasal base tip. It is critical to assess nasal projection, length, tip rotation, and alar/c olumellar relatio when position ing a caud al extens ion graft. Patient s should be told preoperati vely that the nasal tip will be stiffer, with loss of the norm al tip recoil.

Figure 2, continued. With the graft in place (L), the medial crura were secured to the cau dal aspect of the graft to achieve proper tip projection and to address the retracted columella (M). Special care was taken to set appropriate projection , rotation, length, and columellar show. It is critical that the caudal extension grafts be placed in the precise midline .
DEVIATED CAUDAL SEPTUM
A number of maneuvers are at the surgeon ' s dispo sal in the treatment of a caudal devi ation (4,5) . Traditional approaches include scoring the septal cartilage on the co side, thereby relaxing the "spring" of the cartilage. This may be done as a solitary m ver, or in conjunction with a so-called "s winging door maneuver." As illustrated in F a wedge of cartilage excised along the maxillary crest releases the caud al septal a ments and allows the septum to swing to the midline. The midline position may be se with a 4-0 PDS attached to the periosteum adjacent to the oppo site side of the nasal Ethmoid bone splinting grafts or sandwich grafts also may be of benefit in this sit (6).

The deviated portion of cartilag septum may be addre ssed by scoring on the concave side, and the bone graft or graft then be used to splint the septum in a straighter orientation. However, use of the eth bone graft in this location thickens the caudal septum and can contribute to nasal ob tion .

RIB CARTILAGE GRAFT RECONSTRUCTION OF SADDLE DEFORMITY: INTEGRATED DORSAL GRAFT/COLUMELLAR STRUT
The severe saddle-nose deformity may be treated by using autogenous rib cartilage (8,9 Harvest of rib is . escribed later. The rib graft is carved into a dorsal graft and a columell strut, which are interdigitated to recreate an intact L-strut (Fig. 6). This type of structural r construction is particularly useful when there is complete loss of septal support . If an inta nasal septal L-strut is present, onlay dorsal grafting will be sufficient to correct the deformit Great care must be taken to adhere to the prin ciple of "balanced cross-se ctional carving" minimize the risk of graft warping. Once in position , the domes can be sutured over the gra with a transdomal suture. An external rhinoplasty approach allows expo sure for facile plac ment of these grafts . A tip graft allows improved tip projection and definition.

• When placing plumping grafts, the surgeon should overcorrect because the graf tend to settle over time. Additionally, the pocket can be gently irrigated with a tibiotic solution to minimize the incidence of infection . • When performing a caudal extension graft, the surgeon must take special care set appropriate tip projection, rotation, length, and alar/columellar relation. Add tionally, the caudal margin of the graft must be in the precise midline. • The inferior border of the caudal extension graft should be stabilized on the po terior septal angle, soft tissue, or other supporting tissues to avoid postoperativ counterrotation of the extension graft. . • Deviations of the caudal septum can usually be corrected by crosshatching the ca tilage and other conservative maneuvers described in the text. Many cases can b corrected by accounting for excessive length of the L-strut. Inrare cases, subtot septal replacement may be necessary. • When using an integrated columell ar strut/dorsal graft, the surgeon must take sp cial care to stabilize the columellar strut in the midline to avoid shifting or tiltin of the columella . Placement of the dorsal graft into a precise dorsal pocket or s ture fixation of the dorsal graft to the middle nasal vault will miriimize the chanc of the graft shifting to one side. • Symmetric carving of the costal cartilage graft will minimize the chance of th graft warping over time:

12 Harvest of Autogenous Tissue HARVESTING CONCHAL CARTILAGE: ANTERIOR APPROACH Auricular cartilage can be harvested using the anterior or posterior approach (1-6). In most cases, we prefer the anterior approach because we believe it is less traumatic, and the incision heals well if vertical mattress closure is used. If smaller cartilage grafts are needed, then we use the posterior approach. With a marking pen, outline an incision that follows the outer edge of the cavum and cymba concha. This incision should be placed along the portion of the concha that is verti cally oriented in relation to the lateral aspect of the skull (Fig. I). Use a syringe with 1% li docaine (Xylocaine) solution with 1:100,000 epinephrine (or for the lab demonstration, wa ter) to "hydrodissect" the skin of the concha cavum and cymba from the underlying cartilage. Make the incision with a no. 15 blade, and elevate the skin and perichondrium from the underlying cartilage. Dissection proceeds by using appropriate scissors, and also bluntly with cotton-tip applicators. Care should be taken not to damage the soft auricular cartilage, which can tear. The dissection should stop short of the cartilage of the external auditory canal. The radix helicis should be preserved if preservation of ear position is critical. If the entire conchal bowl in excised, the auricle will usually settle closer to the head. Dissect out the desired piece of cartilage, and leave the underlying muscle behind (peri chondrium will remain adherent to the posterior surface of the cartilage), Avoiding deep dissection into the soft tissue minimizes bleeding. Suture the circumferential incision with a 6-0 nylon running mattress suture. Alterna tively, the incision may be closed with interrupted vertical mattress sutures. Special care must be taken to avoid overlap of the skin edges. Place a bolster dressing of Telfa, dental roll, or other suitable material into the concha, and suture it into position to decrease the risk of hematoma. No residual deformity of the pinna is expected with this approach.

A 4-cm to 6-cm incision overlying the eighth rib allows adequate exposure. Disse proceeds to and then through the rib perichondrium. The muscle fibers can be separat stead of cut to minimize postoperative pain. Dissection around the rib is undertaken perichondrially; the pleura is typically closely adherent to the perichondrium. Wit graft completely separated from surrounding soft tissue , the graft is incised and deli under direct vision . The surgeon may elect to place a malleable retractor beneath the it is incised. Saline is placed in the surgical site and Valsalva or positive pressure ap to check for a pleural leak . If a pleural tear is identified, a pursestring suture closure dertaken around a red-rubber suction catheter. The surgeon then requests a "Val salva " the anesthesiologist. The red rubber is then removed and the suture tightened. Saline be placed in the wound and another Valsalva undertaken while the surgeon careful spects for air bubbles. A standard, layered soft-ti ssue closure without a drain is ac plished. Skin edge eversion can be accomplished with everting subcutaneous sutures A chest radiograph is obtained in all patients after rib harvest. In the rare instanc difficulty, the surgeon may wish to consult the appropriate surgical colleague.
HARVESTING CALVARIAL BONE
Parietal bone may be harvested (Fig. 3) through a horizontal incision (typically, 4 6 em) superior to the temporal line . Typically the nondominant side is chosen. Incisi and through the perio steum, followed by subperiosteal undermining, provides prope posure. A drill is used to outline the proposed graft (typical graft size, 1 em to 1.5 em em to 4.5 em) . A trough is drilled through the outer table to the diploe; this allow proper angle for application of a chisel or powered oscillating saw to harvest the grafts fully. Short controlled taps on a sharp osteotome allow increased precision and hel crease the risk of inner-table penetration and dural tear. Patients must be cautioned preoperatively of the risk of possible dural tear and pos brain injury. Any dural entry should elicit an immediate neurosurgical con sultation. The donor site can be contoured with hydroxyapatite cement or any other biocomp bone substitute material. The incision is typically closed in a multilayer fashion .

In female patient s, the incision should be placed in the proxim ity of the in framammary crease . • Postoperative pain can be minimized by cutting as little muscle as possible when dissecting over the costal cartilage . The muscle fibers can be bluntly dissected to expose the costal cartilage and .then retracted to perform the dissection. • Postoperative pain can be significantly decreased by keeping the inferior ribs intact to support the rib cage . With the inferior ribs intact, the patient will have much less pain on inspiration. •• Dissect perichondrium off cartilage, taking special care to elevate perichondrium off the inferior surface of the costal cartilage. By leaving the perichondrium intact over the pleura, there will be minimal chance of pneumothorax. • The incision should be closed in multiple layers. After closing the muscle, fascia, . and subcutaneous tissues, evert the dermal sutures [4-0 polydioxanone suture (PDS)] to provide prolonged support to the skin edges: The wound will remain everted for several months; however, the scar camouflage will be excellent.

13 Incision Closure, Nasal Splint, Postoperative Considerations CLOSURE OF THE MIDCOLUMELLAR INCISION
A single, subcutaneous 6-0 polydioxanone suture (PDS) can be positioned in the dermal tissues to enhance skin-edge eversion and take tension off of the closure (Fig. I). This su ture should provide skin-edge alignment and slight eversion . Excessive eversion will cre ate a deformity that may require many months to resolve. The level of the skin edges must be preci sely aligned with this suture; otherwise, an unsightly scar may result. If there is no tension on the closure, a subcutaneous suture may not be necessary. To close the skin, five 7-0 nylon vertical mattres s sutures are used. The first suture lines up the apex of the inverted V. The next two sutures are angled from medial on the lower flap to lateral on the upper flap to align the closure properly . A 6-0 chromic suture is used to line up the vestibular skin at the corner of the columellar flap. This corner suture is im portant because aberrant healing of this corner can result in a visible notch defect.

CLOSURE OF THE MARGINAL, INTERCARTILAGINOUS, OR TRANSCARTILAGINOUS INCISION
This incision is closed with one or two 5-0 chromi c sutures located laterally that ac advance the lateral crura slightly toward the domes (Fig. 2) This suture advancement w negate the need for an additional suture placed in the region of the domes. All sutures u to close the marginal incision must be examined to make sure there is no distortion of nostril rim or domal region. If the nostril rim is notched, then the suture should be replac taking a smaller bite.
PLACEMENT OF INTRANASAL PACKS, NASAL SPLINT Intranasal Pack
When extensive septoplasty is undertaken, or when partial turbinectomy or turbinopla is performed, the surgeon may wish to place a temporary intranasal pack. The goal is to p vide some compression of the septal flaps and , in the case of turbin ate surgery, to decre the risk of postoperative bleeding. There are a number of commercially available packs. intran asal pack is typically left in place at most overnight and removed the next mornin
External Splint
A great variety of splints are commercially available. In general, after placement of appropriate adhesive, a small rectangular strip of Telfa is placed over the nasal dorsum facilitate removal of the splint in 5 to 7 days. Tape is applied over the dorsum and the na tip. A splint is carefully applied.
POSTOPERATIVE CARE
The sutures should be removed from the columellar inci sion after 5 days. At that poi the incision may be supported with flesh-colored steri-strips for several week s to act as titension taping. Persistent postoperative supratip edema can be treated with subdermal
jections of triamcinolone acetonide (Kenalog; 10 mg/ml , 0.1 ml) injected into the supratip regio n of the nose. The se subdermal injections should not be used in any region othe r than the supratip and should not be used more frequentl y than once every 8 weeks. Superficial injections or excessive use can result in subdermal atrophy.
PEARLS Closure of external rhinoplasty incisions; , • If there is any tension on the closure, a midline 6-.0 PDS suture can be applied to evert the skin edges . Special care must be taken to align the skin edges properly. If the subcutaneous suture is not plac ed properly, the result wili likely be avisible .scar. • The columellar incision is closed with the first 7-0 nylon vertical mattress suture ' : placed in the precise midline. The next two sutures are placed just off midline and ,' , are angled from medial on the lower flap to lateral on the upper flap. This man eu ver will minimize the chances of cre ating a notch at the lateral aspect of the col umellar flap . • After closing the marginal iricision , the surgeon should check the alar margin to ensure that there is no notching of the margin . Thi s occurs if too much mucosa is taken and acts to deform the alar rim. '" ~ The surgeon Should examine the columellar extension of the columellar incision. In mostcases , no suture IS needed in this regi on becau se the vestibular skin is ad equately aligned. In some cases, the vestibular skin is not aligned properly, and a ' 6-0 chromicsuture should be used to align the incision properly. Application of the Cast ' . A strip of Telfa can be applied over the dorsum to allow the cast and tape to bere moved without lifting the dorsal skin off the underlying nasal skeleton, with l'e suIting edema. , • The nose should be loosely taped to avoid vascular compromise. The tissues will
become edematous, and if taped tootight, the tissues may become compromised,
• An Aquaplast cast can be loosely applied to the nose and left in place for 5 days . At,the time of cast removal, adhe sive remover applied through the holes in thecast will loosen the tape. A blunt instrument can be used to lift the cast and tape care- .' fully off the nose. ' Postop erative Care , " • At the time of cast removal, the tape should be loosened with adhesive remover ' that is applied through the holes in the Aquaplast cast and allowed to work for 5 to 10 minutes. ' , , • Digital exercisescan be used in the patient who has deviated nose. These patients ,can perform digital exercises on the nasal bone s to avoid postoperative shifting of the bony nasal vault. This must be done within 10 days after surgery; otherwise, the bones wiil have started to fixate . ' • Postoperative steroid injections can be'used to correct subtle aSYrrllnetries of the nose . Triamcinolone acetonide (Kenalog; 10 mg/ml ) can be injected into the sub dermal region where excessive asymmetric edema is noted. ' ,

Appendix A: Tripod Concept TRIPOD CONCEPT When considering the effect of surgical techniques on the nose, one may think of the tip as a tripod, with each lateral crus composing one leg of the tripod , and the paired medial crura composing the third leg (l ,2). Shortening the two "lateral crura!" legs will cause the tripod to fall in that direction, thereby "rotating and deprojecting" the tripod . Weakening these two legs (as with cephalic resection) is also said to have the same effect (although less so), as the healing forces applied to these weakened legs of the tripod will cause the tip to rotate and deproject slightly over time . Similarly, a columellar strut will strengthen the "medial crural " leg of the tripod. Use of a columellar strut to correct buckled medial or in termediate crur a may increase tip projection and rotation . Even though the tripod concept oversimplifies the dynamics of the nasal tip, it provides those with little experience in rhinoplasty with a method of predicting the effects of specific techniques.

Appendix G: Selected Complications of Rhinoplasty Bossae: A knuckling of lower lateral cart ilage at the nasal tip caused by contractural heal ing forces acting on weakened cartilages. Patients with thin skin, strong cartil ages, and nasal-tip bifidity are especially at risk . Exce ssive resection of lateral crus and failure to eliminate excessive interdomal width may play some role in bossae formation . Polly beak: Postoperative fullnes s of the supratip, with an abnormal tip-supratip relation. This has several etiologies: Failure to maintain adequate tip SUpp0l1 (postoperative loss of tip projection), inadequate cartilaginous hump (anterior sept al angle) removal, and/or supratip dead space/scar formation . Treatment depends on anatomic cau se. If the cartilaginous hump was underresected, then resect additional dorsal septum. One also must ensure adequate tip support. Ma neuvers such as placement of a columellar strut may be of benefit. If the bony hump was overresected, consider a graft to augment the bony dorsum. If a polly-beak is from ex cessive scar formation , consider triamcinolone (Kenalog) injection or skin taping in the early postoperative period, before any consideration of surgical revision. Inverted V deformity: Inadequate support of the upper lateral cartilages after dor sal-hump remov al can lead to inferomedial collapse of the upper lateral cartilages and an "inverted V deformity." In this deformity, the caudal edges of the nasal bones are visible in broad relief. Inadequate infracture of the nasal bones is also a frequent cause. When executing hump excision, it is helpful to preserve the underlying nasal mucoperichondrium (extra mucosal dissection), which provides significant supp ort to the upper lateral cartilages and help s decrease the risk of inferomedial collapse of the upper lateral cartilages after hump excision . When undertaking osteotomies after hump excision, appropriate infra c ture and narrowing of the bony vault must be achieved . Rocker deformity: If osteotomies are taken too high, into the thick frontal bone , the supe rior aspect of the osteotomized nasal bone may project or "rock" laterally when the bone is infractured . This is a "rocker" deformity . A 2-mm osteotome may be used percuta neously to create a more appropriate superior fracture line and correct the rocker defor mity. Dorsal irregularities: After creation of an "open roof" by hump removal, the bony mar gins should be smoothed with a rasp. Any bony fragments should be removed, making sure that all obvious particles are removed from under the skin/soft-tissue envelope. Fail ure to remove all fragments may lead to a visible and/or palpable dorsal irregularity. Nasal valve collapse: The surgeon should recognize the existence of the internal and ex ternal nasal valve . The internal nasal valve area is bounded by the caudal margin of the upper lateral cartilage, septum, and floor of the nose. The external nasal valve refers to the area delineated by the cutaneous and skeletal support of the mobile alar wall. Exces sive narrowness in either of these locations may cause nasal obstruction. Weakness at ei ther of these locations may result in collapse with the negative pressure of inspiration, resulting in nasal airway obstruction. Nasal valve collapse is seen most often as a sequela of overresection of lateral crura or middle vault collapse. Overaggressi ve resection of the lateral crura and the sub sequent postoperative soft-tissue contraction frequently leads to nasal valve compromise.
