Abstract

Orthognathic surgery aims to correct underlying dentofacial deformities and improve facial aesthetics. This study was designed to compare the two-dimensional (2D) lateral facial soft tissue profiles of a group of post-surgical patients (orthognathic group) to a control group of individuals recruited from the local population in the West of Scotland. The relative attractiveness of 112 volunteers (61 females, 51 males), recruited from the local population and aged 18 to 35 years, were rated by a lay panel (four males, four females) who assessed three dimensional (3D) facial images of the volunteers using a Visual Analogue Scale. 16 males and 24 females, rated as being “attractive” and “most attractive” were selected to form the control group. The orthognathic group of 33 patients (17 females, 16 males) was recruited from the Dentofacial Deformity Clinic based at the Glasgow Dental Hospital and the Southern General Hospital, Glasgow. Right lateral 2D facial profile photographs of the control group and the orthognathic group were taken, and digital identification of soft tissue facial lateral profile landmarks completed. Outcome measures were angular, linear horizontal and vertical linear measurements taken from the soft tissue landmarks. Comparison of control males to control females showed that the males had longer faces and more prominent chins than the females. The male orthognathic group had more protrusive lips and chins compared to the male control group, but overall had a similar facial morphology. The female orthognathic group had smaller nasiolabial angles, a longer mid- and lower facial heights and lips and chins which were more prominent than the female control group.
