Alar Retraction
Slightly retracted nasal alae are best corrected by placing cartilage directly along the alar margin. One can support the alar margin by making a small 1 or 2 mm pocket along the rim of the nostril and placing a small, linear piece of cartilage in the pocket, form­ing a rim graft, which adds strength to the slightly weakened or retracted alar rim the alar margin is more significantly retracted than can be repaired by this simpler technique, a com-

Finally, the last maneuver after closing the marginal incision is to evaluate the strength and contour of each alar rim and margin. If any weak­ness or asymmetry is noted, a small incision is made and a 1 or 2 mm wide by 1 cm long rim graft is placed in a separate pocket prior to performance of alar base narrowing and placing the postoperative nasal dressing.

No packing is required, but a short Telfa pledget covered with antibiotic ointment is placed in each nostril to help collect the expected nasal drainage. Cold compresses are applied continuously for 24 to 36 hours. At the end of 1 week, the nasal dressing is removed and no further dressing is required. The senior author finds the use of intralesional steroids in the supratip area helpful in selected cases of thick skin or previously operated cases with a fair amount of fibrous scar tissue in the supratip area.34 The author begins int­ralesional steroids, 0.1 cc of 10 mg/cc triamcinalone (Kenalog), at 2 weeks postoperatively and repeats the steroid administration once or (at most) twice in the first 3-month postoperative period.
Summary
Use of individualized rhinoplasty techniques and the increasing armamentarium of rhinoplastic maneuvers has significantly improved the initial and long-term results of rhinoplasty over the past 25 years. By routinely incorporating a blend of endo­nasal and external columellar approaches to accom­plish the desired aesthetic goals, the surgeon has the

ability to place grafts that not only achieve a better
initial result but also prevent adverse changes to the
overall functional and aesthetic result for patient
in the long term. Because of the increased need for
spreader grafts in the midnasal vault and placement
of alar strut grafts to support the lateral crura, the
use of alar-spanning grafts, the use of interdomal
grafts, and the use of soft-tissue onlay grafts as
well as refinement grafts in the nasal lobule, the
author now uses the external columellar approach
in approximately 75% of all primary rhinoplasties.
By paying attention to detail and using camouflage
cartilage grafting, the author’s revision rates for rhi-
noplasty have been reduced from approximately
7%–8% to 4% of all rhinoplasties.

Introduction
The key to successful nasal tip surgery is precise preoperative analysis, a thoughtful operative plan, and meticulous execution of that plan. To that end, an understanding of the anatomy of the nose, the pathology present, the desires of the patient, and the maneuvers necessary to achieve the desired result are essential. Furthermore, appreciation of the long­term effects of healing has resulted in increased use of external rhinoplasty and of grafting techniques to avoid long-term complications.
Facial Analysis
In order to embark upon nasal surgery, the surgeon must be familiar with the anatomy of the nose, abnormalities of the underlying bony-cartilaginous framework that result in nasal deformity, and the surgical maneuvers necessary to treat deformities and to achieve a satisfying aesthetic and functional result. After mastering an understanding of the anatomy of the nasal tip, the surgeon can predict the underlying structures of the tip via visualiza­tion and palpation. Structural support of the nasal tip is determined by three major and six minor tip-support mechanisms. The major tip-support mechanisms include: (1) the size, shape, and resil­ience of the lower lateral cartilages, (2) the medial crural footplate attachment to the caudal border of the quadrangular cartilage, and (3) the attachment of the caudal border of the upper lateral cartilages to the cephalic border of the lower lateral cartilages. The minor tip-support mechanisms include: (1) the interdomal ligament, (2) the cartilaginous septal dorsum, (3) the sesamoid complex extending the support of the lateral crura of the lower lateral car-
tilages to the pyriform aperture,1 (4) the attachment of the lower lateral cartilages to the overlying skin and musculature, (5) the nasal spine, and (6) the membranous septum.
Anderson’s tripod theory is a helpful method of conceptualizing the nasal tip and the effects any change to one of the three limbs of the tripod will have upon the nasal tip. Two limbs of the tripod are each of the lateral crural legs of the lower lateral car­tilages, and the third limb of the tripod is the joined medial crural feet.
While both the internal and external valves are important in maintaining proper airflow through the nasal passageways, the external valve is of par­ticular interest in tip rhinoplasty. The external valve is formed by the nasal alar sidewall laterally and the columella/medial crural footplate medially. Weak­ness of the lateral crus of the lower lateral cartilage results in dynamic collapse of the nasal alar sidewall and, thus, external valve collapse.
Preoperative Considerations
Preoperative consultation is essential in determin­ing the techniques that will be required to achieve the aesthetic and functional results.2 Consultation with the patient allows the surgeon to understand the patient’s aesthetic and functional goals and whether the goals are realistic. The onus is upon the surgeon to balance the patient’s desires with what is realistically possible given the anatomic limita­tions of the individual nose. History-taking during the consultation affords the opportunity for the sur­geon to document a history of trauma to the nose or of previous rhinoplasty.
Accurate diagnosis is also essential and requires a thorough preoperative assessment, including a

complete facial analysis in addition to analysis of the nose (see Chapter 2). Specific examination of the nasal tip begins with evaluation of the overly­ing skin. Nasal skin that is thick and contains many sebaceous glands does not reveal subtle changes to the underlying framework. Failure of thick skin to contract favorably over time may lead to excess soft­tissue scar, an amorphous nasal appearance, and the soft-tissue pollybeak deformity. Thin skin may more readily show minor deformities and irregular­ities; therefore, camouflaging techniques are more necessary in the thin-skinned patient.
Through palpation of the nasal tip, the sur­geon will gain valuable insight into the nature of the intrinsic support of the nasal tip, especially the septum and septal angle. Palpation also provides the surgeon with an opportunity to determine the nature, volume, strength, and resiliency of the lower lateral cartilages. It behooves the surgeon to evalu­ate the orientation of the lower lateral cartilages; if the lower lateral cartilages are cephalically malpo­sitioned, then alar strut grafts may be necessary to prevent curvature of the alar sidewalls.
On frontal view, the brow-tip aesthetic line fol­lows a gentle curve from the medial brow to the nasal tip with slight narrowing at the middle nasal vault and slight widening at the alar margins. The nasal tip-defining points represent light reflection on the skin overlying the domes of the lower lateral cartilages. Asymmetries and/or width of these tip­defining points should be noted. Also, facial asym­metries on frontal view should be documented and pointed out to the patient. On profile, nasal projec­tion is evaluated using any of a number of tech­niques; however, the Simons relation of the nasal projection to the upper lip length, ideally in a 1:1 ratio, is a helpful and reliable method of evaluat­ing projection. On profile, the nasal-chin relation­ship should be noted, as a patient with inadequate chin projection may perceive the nose to be over­projected when in reality the projection of the nose is adequate. The nasofrontal angle is typically 115– 130 degrees. The nasolabial angle is typically 90–95 degrees in men and 95–115 degrees in women, depending upon the height of the patient. On pro­file, 2–4 mm of columellar show should be visible. A double break is noted between the columella and nasal tip; this double break is created by the inter­mediate crura of the lower lateral cartilages. Finally, on base view, the nose has the form of an equilat­eral triangle, with the lobule representing one-third of the triangle. Weakness of the alar sidewall with
inward curvature should be noted, as this condition may require supporting the sidewall with alar strut grafts.
Digital photography (in the standard views for rhinoplasty with proper lighting and background) is essential to a rhinoplasty practice and provides consistency in photographs. Computer imaging facilitates communication between patient and sur­geon by providing a medium through which the surgeon can demonstrate to the patient realistic surgical outcomes and the limitations that exist­ing anatomy imposes. For example, a patient with inadequate chin projection may benefit from a chin implant. Computer imaging also allows the surgeon to learn about the patient’s desires, such as profile relationships, which may or may not mirror the sur­geon’s preferences. It is important for the surgeon to be honest and accurate about the corrections made on computer imaging. Finally, each patient is asked to sign a waiver stating he/she understands that computer imaging demonstrates a predictive illus­tration and is not a guarantee of the exact aesthetic surgical result.
Technique
Tip rhinoplasty is performed under monitored anesthesia care or general endotracheal anesthesia. The patient is placed on cephalexin 500 milligrams every 12 hours, starting the day before surgery. In the operating room, once an appropriate level of anesthesia is achieved, the nose is infiltrated with 2% lidocaine with epinephrine (1:50,000) and cot­tonoid pledgets soaked with 4% topical cocaine solution are placed in the nasal passageways. After an appropriate amount of time for the epinephrine and topical cocaine to take effect, surgery is begun. Tables 3-1 and 3-2 list the treatment options avail­able to the patients and key instrumentation and materials required during the procedures.
Endonasal Rhinoplasty
Endonasal rhinoplasty is performed via the delivery approach. Access for delivery of the lower lateral cartilages involves bilateral marginal and intercar­tilaginous incisions. The intercartilaginous incision at the limen vestibula is connected with a high septal transfixion incision. If necessary, de-projection of the nasal tip is achieved by extending the high septal transfixion incision inferiorly to release the medial crural feet from the septum; if this maneuver is per-

formed, the medial crural feet are reconstituted to the septum with a 3-0 chromic gut suture on a Keith needle at the end of the surgery.
The septum is approached via the septal trans­fixion incision and septoplasty is performed as indi­cated. Septal cartilage is harvested for rhinoplasty while preserving 10 mm of dorsal and caudal septal cartilage, thus preserving support to the nasal tip and dorsum of the nose.
Once the bipedicled chondrocutaneous flaps are delivered, cephalic margin trim is performed as indi­cated to narrow and define the nasal tip; the cephalic margin trim is conservative, so that 8–10 mm of lat­eral crus laterally and 5–7 mm of lateral crus medially are preserved. One should avoid cephalic trim of the lateral one-third of the lateral crus to avoid lateral wall collapse. Long-term follow-up has shown that weak­ened crura and nasal tip support are subject to con­tracture forces that cause distortions to the nasal tip. Therefore, there has been a progressive movement toward more conservative handling of the nasal tip.

of the external columellar approach. Indications for external rhinoplasty include: revision cases, marked asymmetry of the tip, significantly poor tip support, lower lateral cartilages that are weak, marked under­projection, the foreshortened nose that requires lengthening and de-rotation with extended spreader grafts, the need for spreader grafts to stabilize the middle nasal vault, and cephalic malposition of the lower lateral cartilages that requires alar strut grafts.

Tip-Sculpting Techniques
A graduated approach is used when sculpting the nasal tip during rhinoplasty. First, cephalic margin trim of the lateral crura of the lower lateral carti­lages is performed as described previously. Second, individual treatment of the dome to narrow and gain definition is performed; this is achieved via pinching the dome with Griffith’s Brown forceps, beveling the cephalic edge of the dome unit, and suturing the single dome with a 5-0 Dexon™ suture in a mattress fashion. Prior to suturing the single dome, the vestibular skin on the undersurface of the alar dome is dissected free from the cartilage; this maneuver avoids incorporation of the vestibular skin and mucosa in the mattress suture, thus allow­ing for better scarification and maintenance of the desired narrow single dome. Third, double-dome unit suturing with 5-0 clear Prolene suture is per­formed in a mattress fashion so that the knot rests between the domal units. The combination of indi­vidual dome narrowing and double-dome suturing techniques allows for individual dome treatment,
which might be different for each dome or crus, then reconstitutes them into a single tip-lobular complex. Whereas these techniques will achieve def­inition and narrowing of a broad tip, a bulbous tip that has bulky cartilage may require scoring as well. A boxy nasal tip may require camouflaging in the infratip lobular area to fill in the residual bifidity. A bifid tip may require a full-length shield graft.
Tip Grafts
While suturing techniques may provide increased tip definition and projection, there are times when these techniques fall short of the desired outcome. Therefore, tip grafts are utilized to pro­vide enhanced shape to the poorly defined tip and increased projection. Furthermore, tip grafts may provide improved definition of the infratip lobule. Finally, tip grafts may also be used for camouflaging persistent asymmetries. The graft should be shaped and beveled along its edges to integrate seamlessly with the surrounding cartilaginous architecture. The tip graft is placed after the columellar strut is positioned (Figure 3-1).
The types of tip grafts used include shield grafts, cap grafts, blocking grafts, blanket grafts, infratip lobular grafts, and Peck grafts. A cephalic trans­verse onlay (Peck) graft is placed on top of the nasal dome, thus providing more height and definition to the nasal tip.5 A cap graft is typically sutured to a shield graft in the infratip lobular region to give more infratip lobular length (Figure 3-2). A blocking graft is also used in conjunction with a shield graft and

is sutured into position at the supratip region; the blocking graft prevents rotation of the shield graft and fills in supratip dead space (Figure 3-3).
Controlling Tip Projection
In order to control tip projection, the surgeon must be aware of the factors that influence it, including: the length and strength of the lower lateral carti­lages, the anterior septal angle, the suspensory liga­ment from the anterior septal angle to the lobule, the height of the anterior nasal spine, the attach­ments of the upper lateral cartilages to the lower lateral cartilages, and fibrofatty attachments of the medial crural footplate of the lower lateral cartilages to the caudal septum. Maneuvers that manipulate any one of these factors will influence tip projec­tion. For example, a columellar strut may lengthen and strengthen the medial crura of the lower lateral
cartilages, thus providing a modest increase in tip
projection, and individual dome mattress suture
and transdomal mattress sutures both provide
increased projection of approximately 1–2 mm.
The lateral crural steal technique with intact domes is used to recruit the lateral crura to increase the length of the medial crus at the expense of the lateral crus, thus elevating the tip as much as 2 mm. This provides not only increased projection, but also increased rotation. If more projection is required, then dome division lateral to the dome will further lengthen the lateral crura to increase the tip projection; dome division is typically reserved for relatively thick-skinned individuals. Otherwise, an effective means of providing increased tip pro­jection includes a shield graft.
If the tip is overly projected and requires de­projection, a complete transfixion incision provides
