Objective: This study sought to evaluate the quality of life in patients with class III malocclusion and dentofacial deformity undergoing orthognathic surgery.
Materials and methods: This study evaluated 25 patients with Angle's class III malocclusion submitted to orthognathic surgery through the application of the B-OQLQ questionnaire, over two periods: 30 days before surgery (T0) and 6 months after surgery (T1). The B-OQLQ is a specific questionnaire to assess quality of life in patients with dentofacial deformities.
Results: The average age for women was 26.11 years and for men 31.13 years. The dental discrepancy between the incisors (overjet) was on average 2.55 ± 4.36 mm. There was no correlation between overjet and the level of satisfaction after surgery. There was no statistically significant relationship between patient satisfaction and the type of surgery performed. The results revealed statistically significant differences, showing improvement in the quality of life in the postoperative period of 6 months (p < 0.05), with a positive effect in all four domains of the questionnaire.
Conclusion: Orthognathic surgery significantly improved the quality of life of patients, and the type of questionnaire used (B-OQLQ) proved to be appropriate for the proposed analysis.
