Assessment of BSSO surgery need in adult male and female using photos and silhouette

Abstract

The orthognathic surgery plays an important role in achieving a pleasant-sounding dental, skeletal, and soft tissue which in turn helps an individual with jaw divergences to have function efficiency, aesthetic harmony, and structural balance. Pre-treatment profile photographs of the subjects were taken and morphed forward and backward, in 2 mm steps, until severely prognathic or retrognathic, respectively, to get class III and class II skeletal relation was acquired and the images were labeled from 1 to 5. The morphed profile photos were then camouflaged using Adobe Photoshop CS (v. 5.1) to generate silhouette images. The images were evaluated by three groups of assessors which includes orthodontists, oral surgeons, and laypersons. There was a statistically significant difference between oral surgeons, orthodontists, and laypersons in scoring class II (P < 0.001) for scoring adult females but no significance in rating adult males. There was a statistically significant difference between oral surgeons, orthodontists, and laypersons in scoring class III (P < 0.001) for scoring adult males and females. No difference was observed between scores when evaluated differently with the use of silhouettes or photos.
