Objective. The aim was a quantitative evaluation of how the severity of lower facial profile convexity influences perceived attractiveness.
Study Design. The lower facial profile of an idealized image was altered incrementally between 14 degrees to -16 degrees. Images were rated on a Likert scale by orthognathic patients, laypeople, and clinicians.
Results. Attractiveness ratings were greater for straight profiles in relation to convex/concave, with no significant difference between convex and concave profiles. Ratings decreased by 0.23 of a level for every degree increase in the convexity angle. Class II/III patients gave significantly reduced ratings of attractiveness and had greater desire for surgery than class I.
Conclusions. A straight profile is perceived as most attractive and greater degrees of convexity or concavity deemed progressively less attractive, but a range of 10 degrees to -12 degrees may be deemed acceptable; beyond these values surgical correction is desired. Patients are most critical, and clinicians are more critical than laypeople. (Oral Surg Oral Med Oral Pathol Oral Radiol 2012;114:303-311)
