한국 청년층 구순의 사진 계측학적 연구 = Photogrammetric Study of Lip in Young Population in Korean

다국어 초록 (Multilingual Abstract)

The aim of this study is to establish anatomical dimension of the lip in young population in Korean, using specially designed soft ware with photographic image. We measure 13 anatomical dimensions of lips in 2,229 young people. (917 male, 1312 female, Aged from 18-33 years. Average age 19.7).Statistical analysis of these measurements of large population could offer useful information in facial plastic surgery.The mean measurements are as follows1. Lengths (male/female)Widths of philtrum: 1.11±0.19cm/1.02±0.21cm Heights of philtrum: 1.6±0.24cm/1.47±0.21cmHeights of cupid bow: 0.88±0.16cm/0.83±0.16cmHeight of upper vermilion: 0.74±0.16cm/0.70±0.15cmHeight of lower vermilion: 1.08±0.17cm/1.02±0.15cmHeight of upper lip(Rt.): 1.24±0.2cm/1.23±0.2cmHeight of upper lip(Lt.): 1.24±0.2cm/1.17±0.19cmHalf horizontal length of lip: 2.2±0.26cm/2.11±0.2cmHorizontal length of lip: 4.41±0.4cm/4.25±0.36cmHeight of lower face: 7.1±0.58cm/6.52±0.6cm2. AnglesNasolabial angle: 97.77±11.97°/95.5±11.34°Mentolabial angle: 133.88±14.65°/129.27±13.67°Angle of Cupid's bow: 111.65±13.99°/116.75±16.2°Previous reported photogrammetric measurements was difficult to implement to surgical practice. Because these were printed photographies of the same size. Therefore, in this study, we can measure a lot of objects and items more conveniently and correctly by using proportional program on computer after taking a digital photograph. Consequently, proportional measurements with photogrammetry of lip could be useful and corrective substitute for anthropometrical measuring. These data could be useful reference for preoperative consultation, surgical planning and learning anatomical measurement of lips and adjacent structures.
