Objective The objective of this study was to assess the impact of orthognathic surgery for dental facial deformities on oral health-related quality of life (OHRQoL) in the immediate postoperative period up to at least 1 year after surgery. Study design This prospective study evaluated data from 85 patients. OHRQoL was assessed using the Dutch version of the Oral Health Impact Profile questionnaire (OHIP-14NL) preoperatively (T 0 ), each day for 7 days postoperatively (T 1 –T 7 ) and 4 weeks (T 8 ), 6 months (T 9 ), and at least 1 year (T 10 ) after surgery. The total OHIP score was calculated for each patient, with higher OHIP scores indicating a worse impact on oral health. Patients also completed an extra questionnaire about self-care, discomfort, and experienced pain (rated on a 10-point scale) in the postoperative period (T 1 –T 10 ). Results The mean OHIP score increased sharply at T 1 compared to T 0 but decreased significantly in the first postoperative week. The mean OHIP score at T 8 was still higher than before surgery. However, at T 9 and T 10 , the mean OHIP score was significantly lower than at T 0 ( P < .05). No significant difference in OHIP score was found between gender, age, type of surgery, and indication for surgery. Pain significantly decreased from T 6 to T 0 . The OHIP and pain scores significantly positively correlated at every time point except T 9 . Conclusion The findings indicate that OHRQoL is reduced from baseline in the immediate postoperative period but improves over time. By 1 year, OHRQoL improves significantly after orthognathic surgery in patients with dentofacial deformities.
