RESUMO
This study assessed health-related quality of life (HRQOL) and daytime sleepiness in moderate or severe obstructive sleep apnea patients who underwent maxillomandibular advancement (MMA) surgery. We invited patients who had undergone MMA 1 year ago and preoperative patients to answer a self-administered questionnaire to evaluate HRQOL (Medical Outcomes Study 36-Item Short-Form Health Survey-SF-36 and Functional Outcomes of Sleep Questionnaire-FOSQ) and daytime sleepiness (Epworth Sleepiness Scale-ESS). Twenty-two patients who underwent MMA and 28 preoperative patients participated in the present study. Patients who underwent MMA reduced their daytime sleepiness [5.0 (3.00-8.00) versus 16.0 (9.00-21.00), P<0.01] and increased their quality of life in the following domains: physical role functioning [100.0 (50.00-100.00) versus 62.5 (0.00-100.00), P<0.05], vitality [65.0 (58.75-90.00) versus 55.0 (21.25-67.50), P<0.0], mental health [78.0 (67.00-88.00) versus 62.0 (45.00-75.00), P<0.01], and social role functioning [88.0 (75.00-100.00) versus 69.0 (41.00-100.00), P<0.05]. Patients also improved their rates of sleep-related quality of life in general productivity [4.00 (3.63-4.00) versus 2.9 (2.03-3.75), P<0.01], social outcome [4.00 (4.00-4.00) versus 3.2 (2.00-4.00), P<0.01], activity level [3.7 (3.56-3.88) versus 2.8 (1.64-3.53), P<0.01], and vigilance [3.9 (3.55-4.00) versus 2.7 (2.03-3.67), P<0.01] when compared with the control group. The results suggest that moderate and severe obstructive sleep apnea patients who undergo MMA have positive impacts on quality of life and daytime sleepiness when compared with preoperative patients.
