  • Study Objectives: To assess whether patients with class III malocclusions who underwent bimaxillary orthognathic surgery (BOS) are at an increased risk for obstructive sleep apnea (OSA) and/or a reduction in sleep-related quality of life compared to class III patients treated with orthodontics alone. Methods: Questionnaires were mailed to class III patients who had BOS and a matched control group of class III patients previously treated with orthodontics alone. Subjects were asked to complete the Berlin Questionnaire to assess OSA risk and the Functional Outcomes of Sleep-10 (FOSQ-10) and Epworth Sleepiness Scale (ESS) to assess sleep-related quality of life. Results: 78 subjects in the BOS group responded (29.77% response rate) and 24 subjects in the control group responded (13.71% response rate). Compared to the control group, the surgery group was significantly older, had longer follow-up times, and had more Caucasians. There was no significant difference between the surgery and orthodontic-only groups in their responses to the Berlin Questionnaire or the FOSQ-10. According to the Berlin Questionnaire, 8.97% of the surgery group was at high risk for OSA. The median total FOSQ-10 score for the surgery group and the orthodontic-only group was 18.27 and 18.13, respectively. The surgery group had a significantly lower ESS score of 6.30 compared to the orthodontic-only group score of 6.88. These findings compared favorably with scores for healthy individuals. Conclusions: Patients receiving BOS for the correction of class III malocclusions are at no greater risk for OSA and/or reduction in sleep-related quality of life compared to Class III patients treated with orthodontics alone.
