Method: Between July 2003 and July 2010, 189 patients completed the 14-item Short Form Oral Health Impact Profile (OHIP-14) before orthognathic surgery, 6 weeks after surgery and at the completion of orthodontics as part of an IRB approved prospective study. Subjects with a congenital syndrome, acute trauma, or ASA III or IV were excluded. Repeated measures analysis of variance was used to analyze the changes for the overall OHIP score (range 0 to 56). Higher scores indicate a worse oral health quality of life.
Result: 65% of the subjects were female; average age was 19. 40% had both a maxillary and mandibular ostetotomy; 36% maxillary only; and 24% mandibular only. Before surgery, the most frequently reported items as occurring very often because of problems related to teeth or mouth were “being self-conscious”, uncomfortable eating any foods”, and “embarrassed” (28,13, and 14% respectively). A substantial improvement in the overall score, on average, occurred by 1 year(P<0.0001). Older subjects reported worse OHQOL before surgery and at 1 year after surgery than younger subjects(P<0.0001). Average OHQOL scores were significantly different among the surgery types (P<0.0001). Patients who had a 2 jaw procedure reported the worst OHQOL before surgery and patients with a mandibular procedure (single or two jaw) had slightly worse scores, on average, at 1 year than those who had a maxillary procedure only.
Conclusion: Significant improvement in overall oral health QOL occurred by 1 year after surgery. The type of surgery and the age of the patient at surgery had a significant effect on the change from pre–surgery to post-treatment.
