Materials and Methods: Three groups of patients were interviewed, and orthognathic quality of life questionnaires (OQLQ) was used to assess generic health-related quality of life. They were asked to complete the Kurdish version of the 22-item orthognathic quality of life questionnaire (OQLQ) for control, preoperatively and postoperatively patient. Responses at these different time points were compared using paired t-tests, with the significance level set to P<0.05. Results: There were statistical differences in the satisfaction of four domains (oral function, facial aesthetics, psychological, and social aspects) by these indicated that quality of life was significantly improved by orthognathic surgery (all P<0.001). Results showed statistical differences between groups and suggested that patients with no deformity and those subjected to orthognathic surgery have a better quality of life compared to those with a facial deformity. Conclusion: Dentofacial correction by orthognathic surgery seems to have a positive effect on the quality of life.
