PurposeThis study aimed to assess the effect of health-related quality of life (QoL) among patients with dentofacial deformities who underwent orthognathic surgery, compared to a control group without dentofacial deformities, by using generic oral health and condition-specific approaches.Patients and MethodsIn this prospective study, two questionnaires were administered to 85 patients (31 men and 54 women) who were evaluated before undergoing orthognathic surgery. The Short Form Oral Health Impact Profile Questionnaire (OHIP-14) and the Orthognathic Quality of Life Questionnaire (OQLQ) were administered before and 5–7 months after orthognathic surgery. The control group comprised 96 young university student volunteers without dentofacial deformities.ResultsThe questionnaires were collected 5–7 months post-surgery. The preoperative scores of the patients and the control group were contrasted separately. The respondents' OHIP-14 and OQLQ post-surgery scores were significantly lower (total scores, P < 0.001). The pre-surgery OQLQ all domains scores were significantly higher among the patients than among the controls (total scores, P < 0.001); however, the total scores and three subscale scores of the OHIP-14 in the functional and psychological domains were significantly higher among the patients than among the controls (total scores, P < 0.05). The pre- and post-surgery total OQLQ scores were remarkably different between males and females (P < 0.05). The post-surgery total OQLQ scores were considerably higher in older patients than in younger patients (P < 0.05). All patients in the Class III group who underwent double jaw surgery showed remarkable changes post-surgery (total scores, P < 0.001).ConclusionPatients with dentofacial deformities had a poorer quality of life, compared to the normal population, especially in functional and psychological aspects. Orthognathic surgery had a significant positive impact on QoL. Patients with Class III malocclusion who underwent double jaw surgery seemingly benefitted the most after surgery.
