Survey of patient experiences of orthognathic surgery: health-related quality of life and satisfaction

Abstract

The objective of this study was to assess changes in patient quality of life (QoL) after orthognathic surgery at the Kuwait University Dental Clinic. A self-administered Arabic version of the Orthognathic Quality of Life Questionnaire (OQLQ) and two different visual analogue scales (VAS) were used. Sixty-six patients participated (63.6% female). The deformities were corrected by bimaxillary jaw surgery (83.3%), Le Fort I (9.1%), and bilateral sagittal split osteotomy (7.6%). The most important reasons given for undertaking the surgery were facial aesthetics (80.3%) and bite correction (75.8%). Of the patients who had reported moderate to high levels of problems pre-surgery, the majority reported improvements in facial appearance (91.3%), appearance of the teeth (97.0%), biting (96.3%), chewing (92.3%), and eating function (76.5%). Overall, 93.9% of patients reported better conditions after surgery, and the satisfaction level was very high (VAS 91.6%). The VAS score for QoL increased significantly from pre-surgery (73.0%) to post-surgery (93.6%) (P=0.0001). The OQLQ score was also significantly decreased after surgery, reflecting improvements in the ‘social aspects of dentofacial deformity’, ‘facial aesthetics’, ‘oral function’, and ‘awareness of dentofacial aesthetics’ domains (P=0.0001). Overall, the patients who underwent orthognathic surgery were satisfied and had improved QoL. The satisfaction rate in the present study reflects successful treatment with orthognathic surgery.
