Is Maxillomandibular Advancement Associated With Comorbidity Reduction in Patients With Obstructive Sleep Apnea?

Area of Science:

• Oral and Maxillofacial Surgery
• Sleep Medicine
• Otolaryngology

Background:

• Obstructive sleep apnea (OSA) is a common sleep disorder associated with various medical comorbidities.
• Maxillomandibular advancement (MMA) with genial tubercle advancement (GTA) is a surgical treatment for OSA.
• The long-term impact of MMA with GTA on the overall health profile of OSA patients requires further investigation.

Purpose of the Study:

• To assess changes in medical comorbidity profiles of OSA patients following MMA with GTA.
• To evaluate alterations in diagnoses, medications, weight, and BMI at least two years post-surgery.
• To determine if surgical correction of OSA correlates with improvements in associated health conditions.

Main Methods:

• Retrospective cohort study of 46 OSA patients who underwent MMA with GTA.
• Data collected from Massachusetts General Hospital (2001-2015).
• Statistical analysis included paired t-tests and chi-squared/Fisher exact tests to compare pre- and post-operative variables.

Main Results:

• Patients experienced significant increases in average weight and BMI post-surgery.
• No significant changes were observed in the number of medical diagnoses or prescription medications.
• Weight and BMI increases were most pronounced in patients initially classified as overweight.

Conclusions:

• While MMA with GTA improves OSA symptoms and objective measures, it does not significantly alter the comorbidity profile.
• The persistence of comorbidities suggests they may stem from multifactorial causes beyond airway obstruction.
• Further research is needed to understand the complex etiology of OSA-related comorbidities.
