Effect of Maxillomandibular Advancement Surgery on Blood Pressure in Patients with Obstructive Sleep Apnea: A Pilot Study

Abstract

There is evidence that non-surgical treatment of OSA improves blood pressure (BP) in patients with obstructive sleep apnea (OSA). The objective of this study is to determine the effect of maxillomandibular advancement (MMA) surgery for OSA on BP. 15 patients undergoing MMA surgery for treatment of OSA were enrolled. Ambulatory BP, and BMI were recorded pre- and post-operatively. The average age of the patients was 48.9 years and they had mean preoperative AHI of 40.8 and a mean baseline BMI of 30.8 kg/m2. There were no statistically significant reductions in mean systolic or diastolic BP postoperatively. The BMI was found to decrease on average from 30.8 kg/m2 to 29.3 kg/m2 at follow up (p = 0.01). There were no identifiable relationships between OSA severity and BP. Given the prevalence of OSA and it’s adverse medical consequences, more studies to determine the effect of MMA on BP are warranted.
