Linear photogrammetric analysis of the soft tissue facial profile.

This study digitally analyzes the soft tissue facial profile of a European white population of young adults by means of linear measurements made on standardized photographic records taken in natural head position. The application of the Student t test showed sexual dimorphism in most parameters of the labial, nasal, and chin areas. In general, males had greater heights and lengths as well as greater prominences of these 3 areas. They also had greater nasal and facial depths at the level of the tragus point.
