Purpose: Here we evaluated how orthognathic surgery impacted oral health-related quality of life among patients with dentofacial deformities in the immediate postoperative period and during ≥2 years of follow-up, using the OHIP-14-NL questionnaire.

Methods: This prospective study included 86 patients. Quality of life was assessed using the Dutch version of the Oral Health Impact Profile questionnaire (OHIP-14-NL) preoperatively (T0, baseline), over 7 days postoperatively (T1-T7), and at 4 weeks (T8), 6 months (T9), 1 year (T10), and ≥2 years (T11) postoperatively. Total OHIP score was determined for each patient. Lower OHIP scores indicated higher oral health-related quality of life. Patients also answered questions regarding self-care, discomfort, and experienced pain at all time-points, starting from T1.

Results: Compared to baseline (T0), median OHIP scores were significantly higher from T1 to T8. However, at T9 to T11, OHIP scores were significantly lower compared to baseline (T0) (p < 0.01). OHIP scores were not correlated with gender, age, or blood loss; and did not significantly differ according to surgery type or surgery indication (p > 0.01). Pain scores were positively correlated with OHIP scores for all time-points, except T6 and T10. Pain was not correlated with sex, age, blood loss, surgery duration, surgery indication, or surgery type. Compared to at T1, pain was significantly decreased at T9-T11.

Conclusion: Among patients who underwent orthognathic surgery, oral health-related quality of life was decreased in the immediate postoperative period, but improved at ≥6 months postoperatively. The improvement was significant 2 years after orthognathic surgery.
