Comparative Study of Anthropometric Nasal Anslysis Based on Han Nationality Young Female Adults in Central China

Background: The data of nasal anthropometric measurements could help surgeons perform preoperative or postoperative assessments and decide surgical strategies of the nose plastic surgery and related cosmetic rhinoplasty. The aim of the study was to describe the average values of the nasal anthropometric measurements in Han Nationality young female population in Central China. Methods: All 430 Han Chinese young females were obtained for this study, and their anthropometric features were measured including weight, height, 11 items of linear distance and 4 angles. Seven proportion indices of the soft tissue of the external nose were determined. Related results were compared with the result of other available literature about nasal anthropometry in Han Nationality young females from different regions of China and the other racial/ethnic nasal anthropometry in the world populations. Results: The means of the linear measurements of the external nose in this study were as follows: nasal height (48.9 mm), nasal bridge length (43.3 mm), morphological facial height (110.4 mm), facial width (125.1 mm), intercanthal width (35.9 mm), nasal tip protrusion (21.1 mm), nasal width (35.5 mm), nasal ala length (27.9 mm), nasal ala thickness (4.1 mm), columella height (8.9 mm), columella width (6.0 mm). The means of the angular measurements of the nose were as follows: nasofrontal angle (143.3 degree), nasofacial angle (34.1 degree), nasal tip angle (80.4 degree), nasolabial angle (97.3 degree). Conclusions: There were regional differences of the external nasal anthropometric of the Han Nationality young female adults in China and the racial/ethnic differences of that compared with the some races/ethnic around the world. This study could provide credible and objective reference material for plastic and maxillofacial surgeons for the external nasal soft tissue evaluation and planning of the cosmetic nasal surgery in the Han Nationality young female adults in Central China.
