Photogrammetric Study of Lip in Young Population in Korean

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 follows 1. Lengths (male/female) Widths of philtrum 1.11+/-0.19cm/1.02+/-0.21cm Heights of philtrum 1.6+/-0.24cm/1.47+/-0.21cm Heights of cupid bow 0.88+/-0.16cm/0.83+/-0.16cm Height of upper vermilion 0.74+/-0.16cm/0.70+/-0.15cm Height of lower vermilion 1.08+/-0.17cm/1.02+/-0.15cm Height of upper lip(Rt.) 1.24+/-0.2cm/1.23+/-0.2cm Height of upper lip(Lt.) 1.24+/-0.2cm/1.17+/-0.19cm Half horizontal length of lip 2.2+/-0.26cm/2.11+/-0.2cm Horizontal length of lip 4.41+/-0.4cm/4.25+/-0.36cm Height of lower face 7.1+/-0.58cm/6.52+/-0.6cm 2. Angles Nasolabial angle 97.77+/-11.97degrees/95.5+/-11.34 degrees Mentolabial angle 133.88+/-14.65 degrees/129.27+/-13.67 degrees Angle of Cupid's bow 111.65+/-13.99degrees/116.75+/-16.2 degrees 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.
