20대 한국인 코의 계측치

Abstract

Purpose: The aim of this study is to establish anatomical dimension of the nose and nostril shape in Korean twenties. Methods: Authors measured anthropometry of nose in Korean youths 1,000 individuals (male 363, female 637) and analyzed stastically them. Results: The mean measurements are as follows. 1. The shape of nostrils was classified into 7 types by the angle between both long axis of nostril (male / female). Type Ⅰ (<40°)1.7% / 1.72%, Type Ⅱ (41 - 70°) 26.17% / 29.35%, Type Ⅲ (71 - 100°) 39.94% / 38.77%, Type Ⅳ (unclassified) 3.85% /5.80%, Type Ⅴ (101 - 130°) 20.93% / 17.89%, Type Ⅵ (131-180°) 7.43% / 5.96%, Type Ⅶ (>180°) 0% / 0.47% 2. Lengths (male/female) Width of nasal root: 25.29 ± 2.25 mm / 24.72 ± 2.40 mm Width of nose: 37.63 ± 2.46 mm / 34.77 ± 2.11 mm Width of columella: 7.18 ± 0.92 mm / 6.92 ± 0.86 mm Width of alar: 4.99 ± 1.00 mm / 4.74 ± 0.91 mm Width of nostril floor: 10.98 ± 1.40 mm / 10.13 ± 1.73 mm Protrusion of nasal tip: 17.12 ± 1.95 mm / 16.88 ± 1.84 mm Length of alar: 27.10 ± 2.21mm / 24.66 ± 2.18 mm Length of nasal root: 17.37 ± 2.51 mm / 16.08 ± 2.90 mm Depth of nasal root: 7.83 ± 1.63 mm / 6.82 ± 1.36 mm Length of columella: 8.13 ± 1.40 mm / 7.30 ± 1.46 mm Height of nose: 60.50 ± 8.90mm / 59.14 ± 9.22 mm Height of nasal bridge: 52.68 ± 7.49 mm / 50.57 ± 7.71 mm3. Angles Nasofacial angle: 30.19 ± 3.43° / 29.13 ± 6.31° Nasofrontal angle: 134.88 ± 7.25° / 139.94 ± 6.33° Nasolabial angle: 95.08 ± 8.95° / 95.80 ± 8.93° 4. Nasal index: 72.60 ± 9.57% / 68.21 ± 7.03% Nasal tip protrusion-nasal height index: 45.64 ± 5.21% / 47.09 ± 5.21% Nasal tip protrusion-nasal width index: 32.61 ± 6.83% / 31.63 ± 6.71% Conclusion: These data could be useful reference for anthropometry of nose in Korean twenties.
