Analysis of Facial Asymmetry

다국어 초록 (Multilingual Abstract)

Facial symmetry is an important component of attractiveness. However, functional symmetryis favorable to aesthetic symmetry. In addition, fluctuating asymmetry is morenatural and common, even if patients find such asymmetry to be noticeable. However,fluctuating asymmetry remains difficult to define. Several studies have shown that a certainlevel of asymmetry could generate an unfavorable image. A natural profile is favorableto perfect mirror-image profile, and images with canting and differences less than3°−4° and 3−4 mm, respectively, are generally not recognized as asymmetry. In thisstudy, a questionnaire survey among 434 medical students was used to evaluate photosof Asian women. The students preferred original images over mirror images. Facialasymmetry was noticed when the canting and difference were more than 3° and 3 mm,respectively. When a certain level of asymmetry is recognizable, correcting it can helpto improve social life and human relationships. Prior to any operation, the anatomicalcomponent for noticeable asymmetry should be understood, which can be divided intohard tissues and soft tissue. For diagnosis, two-and three-dimensional (3D) photogrammetryand radiometry are used, including photography, laser scanner, cephalometry,and 3D computed tomography.
