RESUMO
OBJECTIVES: To assess the differences in nasal anthropometric measurements between Korean American women and North American white women and to perform an in-depth nasal index calculation. METHODS: This anthropometric survey included a volunteer sample of Korean American women (n = 72) aged 18 to 35 years with Korean parents and no previous nasal surgery or trauma to the nose. Standardized and referenced frontal, lateral, and basal photographs of the nose were taken of the subjects and 22 standard anthropometric measurements of the nose were determined. Results were compared with published standards for North American white women. In addition, 18 nasal indices were calculated and compared with the published standards for North American white women. RESULTS: The Korean American woman's nose did not fit the neoclassic facial canons. Compared with North American white women, 20 of 22 nasal measurements in Korean American women were found to be significantly different. Nasal indices also revealed significant differences in 16 of the 18 that were calculated. The Korean American woman's nose exhibits less rotation, has a flatter dorsum, and is more flared at the alae, with less definition of the nasal tip. CONCLUSIONS: The average Korean American and North American white female nasal anthropometric measurements are very different. As cosmetic surgery becomes more popular among Asian Americans, our findings bolster the need for a broader view of facial analysis and transcultural aesthetics.

BACKGROUND: The multitude of factors involved with a unilateral cleft lip nasal defect has spurred various surgical techniques in the past. Recently, synthetic materials have been introduced for use in nasal reconstruction. OBJECTIVE: To report on and illustrate the use of porous high-density polyethylene implants in cleft lip nasal reconstruction. DESIGN: A retrospective review of cleft lip nasal reconstruction using porous high-density polyethylene in patients with a unilateral cleft lip defect from January 1, 1993, through June 30, 2000. SETTING: Facial plastic surgery private practice. PATIENTS: Eighteen patients with a unilateral cleft lip without a history of formal rhinoplasty. INTERVENTIONS: All 18 patients required multiple implants, including a columellar strut, premaxillary and prealveolar plumper grafts, a dorsal tip implant, and a unilateral nasal valve batten, using the open rhinoplasty approach. RESULTS: Favorable aesthetic results, as judged by one of us (T.R.), were achieved in all patients. All implants were well tolerated. Postoperative follow-up ranged from 6 months to 7 years. A complication occurred in 1 patient (6%), which resolved with removal of a single implant and intravenous antibiotic therapy. No other complications, including skin erosion or implant extrusion, have been noted. CONCLUSIONS: Porous high-density polyethylene implants for cleft lip nasal reconstruction are well tolerated and achieve good aesthetic results. Porous high-density polyethylene implants lend stability through fibrovascular ingrowth, with integration of the implants to the surrounding tissue.

OBJECTIVES: To assess the differences in facial proportions between Korean American (KA) women and North American white (NAW) women and to quantitatively describe aesthetic facial features in the KA women. DESIGN: Anthropometric survey and facial aesthetic evaluation. PARTICIPANTS: Volunteer sample of KA women (n = 72) who served as models for part 1 of the study and a different sample of KA women (n = 5) and men (n = 5) who served as judges for part 2 of the study. All subjects were between ages 18 and 35 years and had Korean parents and no previous facial surgery or trauma. Intervention For part 1 of the study, standardized and referenced frontal and lateral photographs were taken of the models, and 26 standard anthropometric measurements were determined. Results were compared with published NAW standards. For part 2 of the study, 10 judges evaluated frontal views of the models for facial aesthetics using a visual analog scale. Quantitative analysis was done of the faces of attractive KA women (>90th percentile in aesthetic scores) and comparisons were made with the faces of NAW women and average KA women. RESULTS: The KA woman's face did not fit the neoclassical facial canons. Compared with NAW women, 24 of the 26 facial measurements in KA women were significantly different. Only 9 of the 26 facial measurements were significantly different when the attractive KA women were compared with the NAW women. Nine of the 17 nonsignificant facial measurements were very similar to those of the NAW women; many of these facial features centered around the midface. CONCLUSIONS: Although the average KA woman's facial anthropometric measurements were very different from those of the NAW woman, attractive KA women reflected many of the facial features of NAW women. These findings support the need for ethnically sensitive facial canons and further research into transcultural aesthetics.

The introduction of endoscopes is responsible for the surge in many of the aesthetic facial plastic surgeries in the past decade. This relatively new technology is widely used in upper-third facial rejuvenation and created a natural evolution into the rejuvenation of the central midthird of the face. After careful patient selection and evaluation, several key maneuvers are accomplished to achieve forehead and midface rejuvenation: (1) a subperiosteal dissection of the scalp to the level of the superior and lateral orbital rims and zygomatic arch, (2) incision and release of orbital periosteum, (3) selective myectomies of the glabella muscles, (4) subperiosteal dissection of the midface (from infraorbital rim to the inferior aspect of the maxilla and laterally over the entire zygomatic arch to the gonial angle beneath the masseteric aponeurosis), and (5) suspension and reposition of the malar fat pad, suborbicularis oculi fat, and soft tissue overlying the angle of the mandible. Endobrow-midface lift is a safe and reliable method to rejuvenate the upper two thirds of the face with excellent results while minimizing the morbidities and complications associated with the traditional open procedures.

Secondary nasal deformity associated with cleft lip is a difficult surgical task. For more than 100 years, numerous surgical methods have been created to address the structural changes that occur over time after the primary surgery. Although early surgical methods have relied on various rotational flaps and local tissue manipulation, the recent advent of synthetic materials has provided facial plastic surgeons with more tools to correct the structural and supportive deficiencies. In this article, we describe our 10-year experience with porous high-density polyethylene (PHDPE) implants in secondary cleft-lip rhinoplasty. PHDPE implants have been well tolerated and achieved excellent long-term aesthetic results through fibrovascular ingrowth to the surrounding tissue.

Revision rhinoplasty can be one of the most complicated procedures performed by the facial plastic surgeon. As septal cartilage is often not available in revision procedures, grafting material is often needed. This material can come in the form of autogenous bone and cartilage. Allografts also can be used, including mersilene, expanded polytetrafluoroethylene, and porous high-density polyethylene (PHDPE). In this article, emphasis is placed on the senior author's method in evaluating candidates for revision rhinoplasty as well as techniques using PHDPE. In addition, the properties of the more commonly used allografts are described, including the advantages and disadvantages of using each material in revision rhinoplasty procedures. In comparing the various alloplastic materials available, it is shown that PHDPE has properties that make it an excellent implant for revision rhinoplasty.

Rhinoplastic surgeons continue to seek technical refinements that will result in a consistently reliable postoperative outcome. Over the past 25 years there has been a steady progression away from the simple Joseph reductive rhinoplasty technique toward the use of various grafts to improve both the functional outcomes and aesthetic end result of this procedure. The original reductive template continues to be a major component of a new conceptual paradigm, which has evolved to incorporate the understanding that structural components must be placed to allow a more precise outcome. Specifically, once the nose is reduced to proportions that correspond to the preoperative analysis, separate grafts and implants are placed to prevent a change in the shape of the nose by the constricting effects of the skin shrink-wrapping around the skeletal framework. This article focuses on the use of implants for structural architecture in the senior author's primary reduction-structured rhinoplasty cases.
