Maxillomandibular Advancement for OSA: A 25-year perspective

Area of Science:

• Maxillofacial surgery
• Sleep medicine
• Respiratory medicine

Context:

• Obstructive sleep apnea (OSA) is a common sleep disorder.
• Maxillomandibular advancement (MMA) is a surgical treatment for OSA.
• Long-term outcomes of MMA for OSA are important to evaluate.

Purpose:

• To evaluate the results of maxillomandibular advancement (MMA) for obstructive sleep apnea (OSA) treatment.
• To identify predictors of surgical success and cure in MMA for OSA.
• To assess changes in patient demographics and outcomes over time.

Summary:

• A single surgeon performed MMA on 1010 OSA patients over 25 years.
• Surgical success (RDI < 20) was 73.1% and cure (RDI < 5) was 20.7%.
• Younger age, female gender, lower BMI, and greater skeletal changes predicted better outcomes.

Impact:

• MMA is an effective OSA treatment, with significant improvements in respiratory disturbance index (RDI) and oxygen desaturation index (ODI).
• Predictive factors for successful MMA include patient demographics and cephalometric changes.
• Over time, patients undergoing MMA are younger, have lower preoperative RDI, and achieve better surgical outcomes.
