Objective:To evaluate the effect of orthognathic surgery on the long-term quality of life of patients with presurgical skeletal Class III and to identify its strongest effect-whether esthetic, social, or functional.Materials and Methods:In this retrospective cohort study, the subjects were patients after orthognathic surgery for repairing skeletal Class III. Fifty-five patients who had undergone orthognathic surgery from 2013 to 2018 in the oral and maxillofacial surgery department participated in this study. Each participant completed a modified questionnaire used to assess the patient's esthetic, social, and functional abilities after orthognathic surgery.Results:The rate of esthetic improvement in orthognathic surgery patients was 88%. More than four-fifths (81.8%) of the patients reported improvement in their personal and social self-esteem and confidence. Finally, 40.7% of the patients reported functional improvement. No significant differences between male and female patients were found. All but one of the patients recommended orthognathic surgery for patients with similar problems. One in six (17.3%) patients was dissatisfied with the nasal appearance after the surgical procedure, while almost a quarter (21.8%) reported worsening of their mouth opening, and 25.4% reported worsening of TMJ (Temporo-Mandibular Joint) symptoms. Analysis of the results revealed no statistically significant pattern connecting preoperative overjet or overbite measures with satisfaction rates.Conclusions:In this study, patient satisfaction with the orthognathic surgical procedure was mostly a result of improvements in facial esthetics, followed by psychological well-being and functional abilities. Most dissatisfaction after the orthognathic surgical procedure was related to nasal appearance, mouth opening, and TMJ complaints.
