The contracted nose is a unique entity that follows primary rhinoplasty in the Asian patient. The proposed reasons for this complication are capsular contraction from a silicone nasal implant, pressure necrosis of the lower lateral cartilage resulting from the nasal implant, and infection after alloplastic implantation. The two principal anatomic constituents that must be addressed at the time of secondary rhinoplasty are the lower lateral cartilages and the skin envelope. The lower lateral cartilages should be derotated, projected, and transfixed with an extended spreader graft. Additional onlay grafting may be required to provide greater nasal tip derotation and projection. A transcolumellar incision situated at the columellar-labial angle permits undermining of the upper lip skin to release tension on the incision. If the nasal tip retraction is severe, then the skin envelope may be insufficient to provide coverage to the new cartilaginous framework. In this case, a paramedian forehead flap is recommended to provide adequate tissue coverage. Correction of alar–columellar disparity should be undertaken with composite grafting only after 6 months have transpired to gauge the ultimate relation between the alae and columella. Infection that arises after correction of the contracted nose can be devastating. It should be treated aggressively, but tailored to the severity of the infection. Wound tension along the columella may predispose to skin necrosis and consequent cartilage exposure, which should be managed in turn with prostaglandin emollients to accelerate wound healing and to prevent infection. 相似文献

目的 探讨鼻表浅肌肉腱膜系统的存在及其临床意义。方法 对 3 0具成人尸体行大体解剖观察。结果 表浅脂肪层、肌肉腱膜层由肌肉层和包绕肌肉层表面的深浅两层腱膜组织构成。这样 ,鼻部肌肉和其表面的腱膜从解剖角度上可视为一个特定的结构单位 ,在此称之为鼻部表浅肌肉腱膜系统(NasalSMAS)。且发现鼻部表浅肌肉腱膜系统与面部表浅肌肉腱膜系统的相应结构层次移行。所以 ,又可认为鼻部表浅肌肉腱膜系统是面部表浅肌肉腱膜系统之一部分。其中的鼻部诸肌相互协调 ,共处在一个均衡的结构体系之中。表浅肌肉腱膜系统下方组织疏松 ,无重要血管神经走行是理想的剥离平面。结论 鼻表浅肌肉腱膜系统的完整对外鼻的形态维持具有重要意义 ,鼻部整形手术理想的剥离平面应位于鼻表浅肌肉腱膜系统的深面。 相似文献

Rhinoplasty is often indicated in the older patient, either as an isolated procedure or in continuous or staged combination with other facial rejuvenative operations. The operations must be tempered with conservatism and artistic judgment. The nose of an older person should look natural and inconspicuous and fit the patient's face. Because of possible coronary or hypertensive problems, epinephrine in the local anesthetic solution should be used in lesser concentrations, requiring a longer wait for its full vasoconstrictive effect. Nasal cartilage is tougher, and the nasal bone more brittle in the older patient. In addition to the usual complete rhinoplasty, the partial rhinoplasty is a useful operation for the older individual. 相似文献

There are many ways to reconstruct and make nasal tips more attractive. Sometimes we cannot find the best way unless we at
least remove all surplus from the tip. This may occur in primary or secondary rhinoplasty. In principle, anything is possible
when relocating and reconstructing. However, sometimes we face reality when we uncover the tip: broken or bulging cartilages
that are difficult to put right. For this reason, in 1987 we thought of totally resectioning the alar cartilages in a case
of secondary rhinoplasty with an unsightly appearance. After a year the result was seen to be correct from an aesthetic and
a functional perspective and is still so today. Aesthetically, it kept its shape and did not collapse with nasal respiratory
failure. We covered the end of the crus medialis with a small, temporary, one- to two-layered fascia patch. Except in exceptional
cases, we now use this procedure: Total sectioning of the alar cartilages including the domes, or maintenance of them by preserving
the fibroadipose tip tissue with a suture in the middle of the end of the crus medialis and by covering this with temporary
fascia, which usually has two layers depending on the thickness of the skin of the tip. This procedure is indicated mainly
in secondary rhinoplasty when the cartilages of the tip are completely destroyed, and in primary rhinoplasty when the tip
is excessively wide and bulbous. Our philosophy is, therefore, elegance and beauty of the nasal tip with a solid and equilateral
base without prejudices. 相似文献

Background Preoperative planning and postoperative outcome assessment in rhinoplasty are important. For preoperative planning, some standard
relationships are defined and evaluated primarily with standard photographs, but photographs do not necessarily reflect reality.
Outcome assessment, on the other hand, is mostly subjective, and again, even photographic analyses may not address real changes
after rhinoplasty.
Methods “Rhinometry” is introduced as a clinical method for preoperative evaluations and postoperative judgments, and rhinometric
parameters are defined. Measurements of these parameters were performed for 300 patients before rhinoplasty and in the follow-up
visits 3 months postoperatively.
Results Preoperatively, the nasal length and tip projection for most patients were more than ideal. There was moderate reduction in
nasal length (mean, 9.21 mm) and a decrease in tip projection (mean, 3.34 mm) for the majority of the patients after rhinoplasty.
Reductions in nasal length, tip projection, bony base width, alar base width, and alar base width during a smile were statistically
significant. Patients who underwent surgery using the closed approach had significantly more reduction in nasal length and
less reduction in tip projection. All the patients were satisfied with these pre- and postoperative data. Rhinometry changed
the ideas of the authors about some changes that their operative approaches produce.
Conclusions Rhinometry can change the ideas of plastic surgeons about the changes their operative approaches accomplish and can be a very
useful guide for patients. It is recommended as a part of the pre- and postoperative physical examination of patients undergoing
rhinoplasty. 相似文献

This study aimed to evaluate columellar scar problems after external rhinoplasty in the Arabian population, and to analyze the technical factors that help prevent such problems and maximize the scar cosmesis. The investigation was conducted in university and private practice settings of the author in Alexandria, Egypt. A total of 600 Arab patients who underwent external rhinoplasty were included in the study. All the patients underwent surgery using the external rhinoplasty approach, in which bilateral alar marginal incisions were connected by an inverted V-shaped transcolumellar incision. At completion of the procedure, a two-layer closure of the columellar incision was performed.At a minimum of 1 year postoperatively, the columellar scar was evaluated subjectively by means of a patient questionnaire, and objectively by clinical examination and comparison of the close-up pre- and postoperative basal view photographs. Objectively, anything less than a barely visible, leveled, thin, linear scar was considered unsatisfactory. Subjectively, 95.5% of the patients rated the scar as unnoticeable, 3% as noticeable but acceptable, and 1.5% as unacceptable. Objectively, the scar was unsatisfactory in 7% of the cases. This was because of scar widening with or without depression (5%), hyperpigmentation (1.5%), and columellar rim notching (0.5%). The use of a deep 6/0 polydioxanon (PDS) suture significantly decreased the incidence of scar widening (p < 0.005).The columellar incision can be used safely in the Arab population regardless of their thick, dark, and oily skin. Technical factors that contributed to the favorable outcome of the columellar scar included proper planning of location and design of the incision used, precise execution, meticulous multilayered closure, and good postoperative care. 相似文献

The Japanese nose exhibits a combination of leptorrhine and mesorrhine features that mandates an innovative treatment strategy. Unlike elsewhere in Asia, the Japanese nose often has adequate dorsal height, and at times even dorsal convexity, but maintains a more retruded and amorphous tip configuration. The proposed systematic approach to Japanese rhinoplasty is divided into four categories: (1) dorsal augmentation with or without tip augmentation, (2) dorsal reduction with tip augmentation, (3) tip augmentation only, and (4) dorsal reduction only. The use of autologous and alloplastic materials to achieve the desired aesthetic objectives is described herein. A layered auricular graft technique is outlined for tip surgery, and a unique nasal implant design is discussed. 相似文献
