Nose asymmetry correlates with external nose volume and area: 3D analysis of nasal dimensions in a young Turkish population

Objectives: The nose is a critical facial feature from the cosmetic and functional point of view. The effect of size and symmetry of the nose on beauty and function is a matter of concern for surgeons. In the present study, we performed 3D analysis of nose dimensions and investigated the correlation among them. Methods: Facial mask of 40 (20 males and 20 females) young Turkish adults aged between19 and 26 years were recorded with a 3D scanner. Nose asymmetry, external nose volume, nose area, anatomical nasal index, nasal protrusion index, body height, body weight and body mass index were measured. The correlations among these measurements were investigated. Results: The external nose surface area was measured as 18.2±2.1 cm2 and external nose volume as 8.1±1.3 cm3. A significant correlation was found between nose asymmetry value and external nose surface area (r=0.33, p=0.03), and also between nose asymmetry value and external nose volume (p=0.34, r=0.03). Conclusion: Our study presents 3D quantitative data regarding nasal dimensions and correlation between the nose size and symmetry.
