Harmonized profiloplasty using balanced angular profile analysis.

To evaluate outcomes of aesthetic facial plastic surgery objectively the authors developed a photogrammetric profile analysis method, which they call "balanced angular profile analysis" (BAPA). To develop standards and ways to determine the conformation of various soft tissue segments analytically, 19 mean angular values acquired from the photographs of 71 famous female models (53 Eastern models and 18 Western models) were standardized to provide reference data (recommended aesthetic mean angles [RAMA]), which contain some of the common features and differences between ethnic groups and races. On the basis of the data prepared from angular profile analyses of these photographs, the authors apply their developed method in a practical way to the pre- and postoperative photographs of patients. By using the data provided by BAPA, the clinician can identify delicate profile problems correctly, perform appropriate aesthetic operations, and thus produce better aesthetic results. The authors' harmonized and balanced angular profile analysis can provide surgeons with a way of determining the conformational problems associated with various soft tissue segments of the face. It also offers aesthetic plastic surgeons reference information concerning the creation of an attractive face during the first patient consultation. The authors hope that their straightforward method of profile analysis will provide facial plastic surgeons with a simple tool for profile analysis and surgical planning designed to create an attractive face.

Septal fracture in simple nasal bone fracture.

SUMMARY: Nasal bone fractures are the most common type of facial fractures. Previous studies have shown that most nasal fractures involve the septum, which can provide an obstacle to the successful reduction of nasal bone fractures. In particular, septal fractures in combination with simple nasal bone fractures are usually unrecognized and untreated at the time of injury. Furthermore, systemized treatment protocols and diagnostic tools for septal fractures in the case of simple nasal bone fracture have not previously been presented. In this study, the clinical findings of septal fractures in cases of simple nasal bone fracture were correlated with symptoms, signs, and computed tomography findings and assessed statistically. The patterns of septal fractures in simple nasal bone fractures were assessed by direct vision via hemitransfixion incision. Of the 52 patients with simple nasal bone fracture who presented over a 3-year period and were included in this study, 10 were female and 42 were male, with an average age of 33.8 years (age range, 18 to 61 years). Fifty of these patients (96.2 percent) showed septal fractures, and septoplasty or submucosal resection was performed on 41 patients (78.8 percent) who manifested severe septal fractures of perioperative septal grade 3 or higher. Closed reduction of the nasal bone fracture only was performed on the remaining 11 patients. Among the signs evident at physical examination, mucosal tearing was found to be statistically significant for septal fracture. Computed tomography was found to be very helpful in diagnosing septal fracture but could not predict its severity accurately (Spearman correlation coefficient between computed tomography septal grading and perioperative septal grading, 33.5 percent). Therefore, computed tomography could not be used as a definitive diagnostic modality for septal fractures in terms of deciding whether septoplasty or submucous resection was needed. It is evident that septal fractures are frequent in simple nasal bone fractures that are not combined with other facial bone fractures. This study confirms that there are differences between radiologic findings and perioperative findings. To reduce the incidence of posttraumatic nasal deformity, meticulous physical examinations with subsequent septoplasty or submucosal resection are needed in the treatment of simple nasal bone fracture.

Balanced angular profile analysis.

To evaluate current preferences and ethnic differences of female soft-tissue profiles, 71 profile photographs of famous female models were collected from Internet Web pages and divided into four groups (Korean, 22; Japanese, 15; Chinese, 16; and Western, 18). Eleven soft-tissue landmarks were recorded on each photograph and 16 angular measurements were made by using V-ceph (CyberMed, Inc., Seoul, Korea). Data from each group are presented to show the means, ranges, p and F values, standard deviations, and standard errors of each measurement. In addition, individual measurements for each group were compared with those of the other groups by one-way analysis of variance using a p value corrected for multivariable testing. Between-group mean value differences were calculated using a Tukey's studentized range test (HSD), at a significance level of p = 0.05. Most of the variables were similar in the groups. Significant between-group differences (p < 0.05) were found for angle of alar curvature point, profile convexity, interlabial contour, and nasolabial contour. In addition, we divided all data into two groups (Western and Asian). The t test (with significance level set to p = 0.05) was performed to compare the two. Significant between-group differences (p < 0.05) were found for angle of alar curvature, angle of labiale inferius, profile convexity, and lower lip projection angle, but no significant racial differences were found in terms of several profile angles. These findings suggest that point of ala curvature point, subnasale, and the labiale inferius of Asian models may differ from those of Western models. These peculiar angular patterns of Asian models led the authors to create a new characteristic angular concept, termed the "ethnic pyramid," which is composed of soft-tissue profile points of alar curvature point, subnasale, pronasale, and labiale inferius. This ethnic pyramid describes the characteristic patterns of the ethnic differences. The results of this study suggest that the soft-tissue profiles of famous female models have some common features but also show differences among ethnic groups and races. This simple method of profile analysis may provide aesthetic surgeons with a simple formula and reference data for creation and application of an attractive face. On the basis of their balanced angular profile analysis data, the authors suggest that appropriate and harmonious aesthetic operations reflecting these differences should be considered.
