sion is made by incising vestibular skin along the caudal margin of the lateral crura. e incision begins laterally just beyond the location where the caudal rim of the lateral crus diverges from the alar rim to move cephalad. It continues me­dially, following the caudal rim of the lateral crus and medial crus, nally end­ing at the columellar-lobular junction. e incision may be extended further on both ends to facilitate cartilage delivery.
An intercartilaginous incision is created beginning at the lateral end of the limen vestibuli and extends medially mm caudal and parallel. e incision is then curved into the membranous septum anterior to the valve region where it meets the transxion incision. Skin is then separated from the cartilage starting at the infracartilaginous incision, ceasing at the lateral and medial extensions of the incisions. Such undermining connects the intercartilaginous and infracartilagi­nous incisions, while creating a bipedicled ap of cartilage lined with vestibular skin. It is then delivered from the nostril to expose the supercial surface of the cartilages.
On delivery, the cartilage is oen distorted as the ends are tethered. A right­angle hook placed in the apex can help more accurately identify the dome area aer delivery. With the hook secured the cartilage is pulled out the nostril and the dome marked. With dicult delivery, the incisions are extended as needed and so tissue undermined to improve access. Following adequate delivery and marking of the domes, cartilage modication is performed.
e cartilage delivery technique permits direct exposure of the lower lateral car­tilages, providing greater exibility compared with cartilage-splitting technique. e foremost disadvantage of the cartilage delivery technique is the associated distortion of delivered cartilage making it dicult to conceptualize the nal car­tilage shape once returned deep to the skin. Placing the cartilage back into the appropriate location and suturing the caudal rim back into original position is problematic if crosshatching is not used for alignment. Inaccurate incisions and suturing may result in alar rim notching and obliteration of so tissue facets.
Distortion of the delivered cartilage is the primary disadvantage with the carti­lage delivery technique.

e open approach allows comprehensive diagnosis of existing deformity and optimizes surgical intervention as a result of maximal exposure. Inspection of the cartilages in their natural anatomic position and determining the subse­quent inuence on tip appearance is more easily accomplished through the open approach.
Advantage of the open approach is optimal visualization of the undisturbed nasal infrastructure providing a more accurate diagnosis and treatment.
Furthermore, it is easier to observe the inuence that each maneuver has on the overall cartilaginous framework. e nal modied framework can be acurately assessed before the conclusion of surgery. e skin envelope is redraped and the entire nose is once again inspected and palpated to ensure the desired result. Liing the skin envelope and making the appropriate changes can easily address any irregularities.

Additional advantages of the open approach include the following:
Enhanced ability to use both hands
Improved control of bleeding limiting postoperative edema
Greater ease of contouring and suturing existing structures
More accurate placement and xation of gras
Optimal for teaching rhinoplasty
Open approach rhinoplasty has enjoyed great popularity because of the optimal exposure for diagnosis and surgical intervention. It is extremely useful in patients with unusual deformities of the nasal tip, for secondary rhinoplasty or posttrau­matic noses, and for nasal deformities associated with cle lip.
Disadvantages to the open approach include the transcolumellar scar and poten­tial for greater postsurgical edema. A closed approach with broad undermining would produce similar edema. e incision should be placed at the narrowest portion of the columella, typically where the medial crura begin to are. Straight line incisions are avoided to prevent scar contracture and notching of the scar at the transition from the external to internal columellar skin. Instead, an inverted­V or stairstep pattern is recommended. With accurate closure, a ne, narrow scar is produced on the undersurface of the nose that is imperceptible. Critics of open rhinoplasty have reported prolonged tip edema, extended operating time, and an inability to create small gra pockets.
KEY POINTS
Surgery of the nasal tip requires a comprehensive knowledge of nasal anatomy and support.
When operating on the nasal tip it is best to follow a graduated approach with constant reassessment before each maneuver.
To rotate the nasal tip, the surgeon must identify and remove anatomic struc­tures resisting upward rotation.
Open rhinoplasty provides optimal exposure to the nasal framework. Such exposure allows comprehensive diagnosis and greater accuracy in surgical ex­ecution.
Fibrous attachments of the lower lateral cartilages to the upper lateral carti­lages, piriform aperture, and caudal septum are responsible for nasal tip sup­port and position.
e tripod concept facilitates an understanding of how surgical modications to the medial and lateral crura inuence tip position.
Suturing ared medial crura together provides a small increase in nasal tip projection.
Part Four e Tip348

If changes in the shape of the columella, alteration of the alar-columellar re­lationship, and/or columellar-labial transition are desired, this pocket can be dissected closer to the columellar skin.
Open approach placement of a columellar strut provides superior control and a greater increase in tip projection.
Lateral crural steal involves advancing the lateral crura medially and using hor­izontal mattress sutures to create new tip-dening points on each lateral crus.
A graduated approach to increasing tip projection includes placement of a columellar strut gra, followed by lateral crural steal with xation to the strut, and if necessary, tip graing may also be used to achieve greater tip projection.
Decreasing tip projection should follow a graduated approach. Disruption of so tissue support is performed with reassessment of tip position. If greater deprojection is needed vertical transection of the lateral and/or medial crura with cartilage overlap allows posterior displacement of the tip and may be re­quired.
Decreasing tip projection can be accomplished incrementally by elevation of skin envelope, violation of tip supporting brous attachments, addressing the dorsal septum, and then transection and overlap of lateral and/or medial crura.
Increasing rotation of the nasal tip requires evaluation of each factor that may limit upward rotation. e result of such assessment guides surgical decision making.
Narrowing the angle of divergence and medializing the tip-dening points is accomplished by tip suture techniques and/or by cephalic trim of the lower lateral cartilages.
Reducing fullness in the nasal tip is accomplished by cephalic trim of the lower lateral cartilages, suturing of the domes to increase angulation, and by place­ment of lateral crura strut gras to correct severe convexity and correct crura position.
Creating supratip break places the tip-dening points  to mm above the septal angle; varying on skin thickness dierences between the dorsum and tip.
Distortion of the delivered cartilage is the primary disadvantage with the car­tilage delivery technique.
Advantage of the open approach is optimal visualization of the undisturbed nasal infrastructure providing a more accurate diagnosis and treatment.

Advanced Suture Techniques
Ronald P. Gruber  Aaron J. Berger  Edwin Kwon
Rhinoplasty is considered by most to be the most dicult of all aesthetic
plastic procedures. For many years the nasal tip was considered to be the most complex part of rhinoplasty. e broad, bulbous, round nasal tip was treated with much cartilage resection, scoring, and bruising, all in an attempt to reduce its size and bring about a normal shape. Unfortunately, postoperatively, very few nasal tips were of very high quality. It was eventually recognized that destructive techniques simply were not working and that remodeling and remolding with sutures would be the best way to achieve controllable and replicable results.
BACKGROUND
Suture techniques to control the cartilages of the nose and therefore nasal shape originated with Jacques Joseph in the s. He developed the basis of today’s columellar-septal suture when he used sutures to secure the tip complex to the septum. Modern techniques began in large part with Tardy et al, who applied a transdomal suture to control dome width in the closed approach. In the s Daniel introduced his domal denition suture in the open approach. is was followed by a urry of suture techniques, which became part of the rhinoplasty evolution and continue to be developed today. Guyuron and Behmand provided a review of commonly employed suture techniques. A signicant number of sur­geons have contributed enormously to this eld. us to favor the suture techniques discussed in this chapter.
INDICATIONS AND CONTRAINDICATIONS
ere is an indication for suture techniques in rhinoplasty, particularly primary rhinoplasty, in virtually every case. Any nasal tip that is not normal and that re-

quires reshaping is likely to benet from the suture techniques described here. ere are virtually no contraindications.
In a secondary case, suture techniques are used rst to reshape the nasal tip. If suture techniques do not achieve the result because, for example, the cartilages are decient or defective, cartilage graing is used to restore the tip. However, the surgeon will likely select suture techniques as a rst choice, because they are simple, fast, safe, and save donor cartilage.
Tip contour is controlled largely with various suture techniques.
PREOPERATIVE ASSESSMENT AND PLANNING
e patient for a rhinoplasty is assessed for any tip abnormalities. ese include bulbosity (broad tip, wide tip, round tip, or boxy tip). When any of these abnor­malities is present, the plan is suture tip-plasty. e rst step of that plan is to convert the tip complex to a tripod in which two of the “legs” are lateral crura mm wide. Wide lateral crura are relatively easy to control with sutures and can be relied on not to collapse. Crushing, bruising, scoring, or resection of the lat­eral crura to a smaller size causes weakness and complications such as rim col­lapse and alar retraction.
e third leg of that tripod is the paired middle/medial crura. e surgical plan therefore is to separate the cephalic part of the lateral crus to leave such a tripod and plan on shaping the tripod to normal anatomy. An anatomic model helps the surgeon determine what that shape should be rather than trying to memorize the various angles and dimensions.
e techniques described can all be done, and have been done, using the closed approach. e tip cartilages have to be delivered with intercartilaginous and mar­ginal incision, and the process is not quite as exacting, but it can be done that way.

OPERATIVE TECHNIQUE
Suture Tip-plasty
Aer the nose is opened and the tip cartilages ex­posed, an appropriately wide lateral crus is devel­oped that should be approximately mm wide. A lateral crus of that width is easiest to manipulate with sutures and has enough structural integrity to avoid collapse.
However, the surgeon must decide whether the cephalic component (sometimes called the cephalic island) needs to be preserved to avoid or minimize alar retrac­tion (see Chapter ). Otherwise, it should simply be excised. Aer that decision is made, a series of suture techniques are applied as needed to create a normal­shaped nasal tip framework.
Transdomal Suture
A - PDS horizontal mattress suture on P- needle is applied to the dome start­ing at the caudal end so that the knot is not in the supratip region. If the dome is dicult to identify, the tip cartilages are gently squeezed with forceps, which causes the dome to become more apparent. e suture is not tied too tight, but to the appropriate width. Aer that is done, the domes take on an axis, and the separation between thoses axes is usually about  degrees. Some improvement to the lateral crus convexity also occurs.
e transdomal suture narrows the dome.
Transdomal suture
Hemitransdomal suture

Hemitransdomal Suture
When eversion of the lateral crus is desired, a hemitransdomal suture is use­ful and oen replaces the transdomal suture. While the dome is held with a
ceps, a - PDS simple suture is applied to the cephalic side of the dome.
for is squeezes only the cephalic side, causing the lateral crus to evert and even straighten slightly.
e hemitransdomal suture narrows the dome and everts it.
Eversion
e two sutures (transdomal and hemitransdomal) can be compared side by side. is small amount of eversion is important if it is to minimize a pinching of the domes and a resultant rim concavity.
