Photogrammetric Facial Analysis of Attractive Celebrities Using the Glabella for Planning Rhinoplasty and Analyzing Surgical Outcomes

ABSTRACT

BACKGROUND: Identifying problems and making a surgical plan through a preoperative analysis is important in facial aesthetic surgery. Thus, popular conceptions of an attractive face must be analyzed beforehand. The landmarks used as reference points may change after rhinoplasty, resulting in errors in the prediction and assessment of outcomes. To reduce such errors, it is advantageous to use reference points and landmarks that are subject to minimal variation. This study measured and analyzed landmarks with little preoperative and postoperative variation in rhinoplasty, and established appropriate standards for landmarks indicative of ideal profiles. METHODS: A photogrammetric analysis was performed of 80 famous and attractive celebrities from Korea, Southeast Asia, Japan, China, and America. The nasofrontal angle, nasal angle, nasolabial angle, angle of facial convexity, and angle of total facial convexity were measured. RESULTS: The angle of total facial convexity differed significantly among countries (P=0.013). No significant difference in nasal angle, facial convexity, or total facial convexity was observed between Western and Eastern countries. A significant difference in the nasofrontal angle (Asian 138.66°, Western 134.35°; P=0.006) was observed. The nasolabial angle (Asian 97.09°, Western 104.59° degrees; P=0.007) was significantly more acute in Asian than in Western subjects. CONCLUSIONS: In this study, we performed a more accurate analysis using the glabella instead of the nasion to measure the facial profiles of patients planning to undergo rhinoplasty and proposed standard values through an analysis of ideal and attractive facial profiles.
