Psychologic implications of orthognathic surgery in patients with skeletal Class II or Class ill malocclusion.

The psychologic profile of 100 consecutive patients undergoing orthognathic surgery for correction of Class II or Class III malocclusion was monitored in a prospective observational study. Patients and their relatives or friends completed questionnaires about their self-image before surgery, 6 weeks postoperatively, and 6 months postoperatively. Preoperatively, patients with Class III malocclusion felt significantly less attractive (P = .03), had slightly higher attention to physical appearance, and had slightly stronger feelings of insecurity regarding their facial appearance compared with Class II patients. Grading of attractiveness/self-confidence improved significantly in Class III patients at 6 weeks postoperatively (P = .006), while in Class II patients the improvement was less pronounced and only significant at 6 months postoperatively (P = .002). Grading of attractiveness/self-confidence by relatives/friends of patients with Class II and Class III was similar preoperatively, but was significantly higher for Class III patients 6 weeks postoperatively in comparison with Class II patients (P = .048). These data indicate that the psychologic profiles are significantly different between Class II and Class III patients preoperatively and show different dynamics postoperatively.
