Ideal soft tissue facial profile in Iranian females.

This study was carried out on 100 photographs of Iranian young adult females, ages ranging from 16 to 40 years. Each photograph was scanned, the image was projected onto a computer monitor, and computerized sketches were obtained from them. With the help of a review committee, 10 of the best sketches were selected and analyzed. The linear and angular measurements were made to the nearest 0.5 mm with dial calipers and a standard protractor with 0.5 mm increments. A total of 15 measurements were analyzed in the study. Our measurements were compared with North American Caucasian female. The upper and lower lip projections were significantly more prominent in our study. Total facial angle was less prominent in our study in comparison with the North American Caucasian females. These findings led to the conclusion that Iranian females have faces which are more convex than North American Caucasian females. The frontonasal angle was more prominent in our study in comparison with the Farkas study of North American Caucasian females. Other linear and angular measurements did not show significant difference between our study and North American Caucasian females.
