An improved method for treatment of facial asymmetry secondary to jaw deformity.

Current methods of treating facial asymmetry secondary to jaw deformity do not take into consideration asymmetry in the gonial angle areas. An instrument was developed for measuring such asymmetry. A second instrument was developed that permits predictable repositioning of the jaws during surgical correction. Use of these two instruments is illustrated in eight cases. Results suggest that it is now possible to correct facial asymmetry, including posterior facial asymmetry, in a one-stage surgical procedure.
