Abstract

Photogrammetric analysis and study of the beauty sense for lip are important for the planning of aesthetic and reconstructive lip surgery. The purpose of this study is to determine average value of the lip dimensions and to classify shape of the lip in Korean adult female. We took measurements from life sized photographs of the one hundred Korean adult female aged from twenty to forty nine years. We have classified shape of the lip as seven types by measured heights of upper and lower vermilion. Measured data were analysed to obtain mean, standard deviation and proportional indices. The following results were obtained.1. The mean and standard deviation of photogrammetric measurements of lip were presented below; philtral length was 15.2+/-2.0 mm, height of maximal point of Cupid's bow was 9.7+/-1.5 mm, upper vermilion height was 8.2+/-1.4 mm, lower vermilion was 10.9+/-1.4 mm, lower facial height was 67.5+/-4.5 mm, mouth width was 46.9+/-3.6 mm, bialar was 37.8 +/-2.6 mm, nasolabial angle was 87.0+/-9.0.2. The standard proportional indices of lip dimension were presented below; mouth width-lower facial height index was 69.6+/-6.3%, bialar width-lower facial height index was 56.2+/-4.5%, nose-mouth width index was 81.0+/-5.5%, upper and lower vermilion height-lower facial height index 28.3+/-3.5%, upper and lower vermilion height-mouth width index was 40.9+/-5.3%, philtral length-mouth width index 32.6+/-5.2%, upper vermilion-lower vermilion height index was 76.4+/-13.8%. 3. The classification of shape of the lip is presented below; standard type is most frequent type(55%) and the upper and lower vermilion height is measured within mean +/- 1 SD, second most common type is upper thick type(10%), upper thin type is 9%, lower thick type is 8%, both thick type is 7%, lower thin type is 6%, both thin type is 5%.
