Sculpturing the broad face to 'golden proportions'

open access: yesPlastic Surgery, 1994
The oval shaped face is generally accepted as having the most beautiful configuration and the ‘golden proportion’ (1:1.618) ideal. Such a configuration can be altered to a square or rectangular shape by an increase in width of the lower face. This broadened morphology can be caused by three anatomical elements: hypertrophy of the masseter muscles ...
