Evaluation of oral health related quality of life in patients undergoing orthognathic surgery

Objective: To evaluate and compare the oral health related quality of life (OHRQoL) before and after surgery in patients undergoing orthognathic surgery. Materials and methods: A total of 41 patients who scheduled for orthognathic surgery were included. Interviews were conducted to assess the OHRQoL based on the Oral Impact on Daily Performance (OIDP) index preoperatively as well as 3 and 6 months postoperatively. The overall OIDP scores and condition-specific OIDP (CS-OIDP) scores attributed to malocclusion, facial dissatisfaction and neurosensory disturbance were evaluated. Results: The average overall OIDP scores of preoperatively, 3 and 6 months postoperatively were 18.3, 9.4 and 7.3, respectively. There were significant differences of overall OIDP scores between preoperatively and both 3 and 6 months postoperatively at 0.006 and <0.001. Moreover, there were significant differences of CS-OIDP scores attributed to malocclusion and facial dissatisfaction when compared preoperatively and both 3 and 6 months postoperatively (p-value <= 0.05). Conclusions: Orthognathic surgery improved OHRQoL in holistic view. Moreover, specific conditions including malocclusion and facial dissatisfaction were improved significantly after surgery.
