Abstract
PURPOSE: To compare morbidity and mortality rates in obstructive sleep apnea (OSA) versus dentofacial deformity (DFD) patients undergoing equivalent maxillofacial surgical procedures. PATIENTS AND METHODS: Patients with OSA who underwent maxillomandibular advancement with genial tubercle advancement in the Massachusetts General Hospital Department of Oral and Maxillofacial Surgery from December 2002 to June 2011 were matched to patients with DFD undergoing similar maxillofacial procedures during the same period. They were compared regarding demographic variables, medical comorbidities, perioperative management, intraoperative complications, early and late postoperative complications, and mortality rate. RESULTS: A study group of 28 patients with OSA and a control group of 26 patients with DFD were compared. The patients with OSA were older (41.9 ± 12.5 years vs 21.7 ± 8.6 years), had a higher American Society of Anesthesiologists classification (2.0 ± 0.5 vs 1.3 ± 0.6), and had a higher body mass index (29.6 ± 4.7 kg/m(2) vs 23.0 ± 3.1 kg/m(2)). They also had a greater number of medical comorbidities (2.4 ± 2.3 vs 0.7 ± 1.0). More OSA patients than DFD patients had complications (28 [100%] vs 19 [73%], P = .003), and the total number of complications in the OSA group was higher (108 vs 33, P < .001). Of the complications, 13.9% in the OSA group and 3.0% in the DFD group were classified as major. The absolute risk of a complication was 3.9 for the OSA group versus 1.3 for the DFD group. The relative risk of complications in OSA patients compared with DFD patients was 3.0. No difference in mortality rate was found. CONCLUSIONS: The patients in the OSA group were older, had more comorbidities, and ultimately had a greater number of early, late, minor, and major complications than those in the DFD group. The incidence of death in both groups was zero. Maxillomandibular advancement appears to be a safe procedure regarding mortality rate, but OSA patients should be counseled preoperatively regarding the relative increased risk of complications.
