Impact of maxillomandibular advancement on oral health related quality of life in patients with obstructive sleep apnea: A longitudinal study of the oral health impact profile (OHIP-14)

Abstract

BackgroundThe aim of this study was to evaluate the impact of maxillomandibular advancement (MMA) on oral health-related quality of life (OHRQoL) in obstructive sleep apnea (OSA) patients prior to, immediately after, and up to 1 year after surgery. MethodsIn this prospective study, OHRQoL was measured with the use of the Dutch version of the Oral Health Impact Profile questionnaire (OHIP-14NL). A total of 19 patients were asked to complete the questionnaires prior to surgery (T0), on the first 7 days post-surgery (T1-T7), and 1 month (T8), 6 months (T9), and at least 1 year post surgery (T10). The baseline OHIP score was compared with the post-surgery scores using the Wilcoxon signed-rank test with Bonferroni correction (significance at P < .005). ResultsCompared with the baseline, the OHIP score significantly increased in the first month after MMA. At 6 months (T9) and 1 year (T10), the OHIP score decreased compared relative to scores in the immediate postoperative period (T1-T8). However, there was no significant difference found in comparison with the baseline (T0). ConclusionThis study indicates that in OSA patients who undergo MMA, OHRQoL deteriorates in the immediate postoperative period. However, at 6 months to 1 year post surgery, OHRQoL does not significantly differ from its baseline value prior to MMA.
