Nasal shapes and related differences in nostril forms: a morphometric analysis in young adults.

Being aware of the morphologic differences in the nasal anatomy between men and women during the cosmetic rhinoplasty is essential because feminization of a male nose is not a very rare complication. Although there is no difference in the techniques of male and female rhinoplasty, the anthropometric differences have to be considered. This morphometric study evaluated the nasal shapes in both sexes and the related differences in the nostril forms. The nostril forms were separated into 4 main groups such as teardrop, heart shaped, round, and triangular. In this landmark-based morphometric study, significant relations of nostril forms to the nasal shape, frontonasal, and nasolabial angles were found. The results of this study should make us think about these relations of nostril forms to the nasal shapes and should be a basement for further clinical studies enhancing the plans of the corrective surgery.
