Nasofacial Anthropometric Study Among Students of Shiraz University of Medical Sciences, Iran: A Population Based Study.

Anthropometry is a scientific study of linear dimensions and angles of living subjects. Knowing the details and anthropometric properties of nasofacial for each specific ethnic group is important for cosmetic operation as well as identifying individuals. In this study, facial and nasal anthropometric factors were studied in students of Shiraz University of Medical Sciences. In a cross-sectional study, 200 students of Shiraz University of Medical Sciences (100 male and 100 female and age range of 18-30 years) were selected. Nasal width (NW), nasal length (NL), nasal height (NH), face height (FH) and face width (FW) were measured in and the nasal (NI) and facial index (FI) were calculated for each case. Then, the data were analyzed using SPSS-22. The mean age was 21.84 ± 3.18 years. There were significant differences in the facial and nasal measurements including FH (P = 0.0001), FW (P = 0.0001), FI (P = 0.0001), NL (P = 0.002), NH (P = 0.001), NW (P = 0.0001) and NI (P = 0.0001) of sex groups. The most common types of face were mesoprosopic (36%) and hyperleptoprosopic (38%) types and and platyrrhine (63%) were mostly frequent. Based on the findings, all students of Shiraz University of Medical Sciences had mesoprosopic (36%) and hyperleptoprosopic (38%) types of face and platyrrhine type of nose. As well, a sexual dimorphism was recorded according to the nasofacial measurements in Iranian population that should be considered in the cosmetic operations. Sexual dimorphism and differences between different populations were recorded.
