Maxillomandibular Advancement for OSA: A 25-year perspective

Area of Science:

• Surgical innovation in treating sleep-disordered breathing.
• Advanced craniofacial surgical techniques for airway management.

Background:

• Obstructive sleep apnea (OSA) is a common condition with significant health implications.
• Maxillomandibular advancement (MMA) is a surgical option for moderate to severe OSA.
• Evaluating long-term outcomes of MMA is crucial for treatment optimization.

Purpose of the Study:

• To assess the efficacy of maxillomandibular advancement (MMA) in treating obstructive sleep apnea (OSA).
• To identify predictors of surgical success and cure in MMA for OSA patients.
• To analyze trends in patient demographics and outcomes over a 25-year period.

Main Methods:

• Retrospective analysis of 1010 patients undergoing MMA for OSA over 25 years.
• Exclusion of patients with prior revision MMA surgery.
• Collection and analysis of pre- and post-operative demographics, cephalometrics (SNA, SNB, PAS), and polysomnography data (RDI, ODI).

Main Results:

• Mean RDI and ODI significantly improved post-MMA.
• Overall surgical success rates were 73.1% (RDI) and 79.4% (ODI); cure rates were 20.7% (RDI) and 71.9% (ODI).
• Younger age, female gender, lower BMI, and specific cephalometric changes (SNA, PAS) predicted better RDI reduction and cure.

Conclusions:

• MMA is a highly effective treatment for improving OSA.
• Patient selection based on prognostic factors and maximizing advancement can enhance surgical outcomes.
• Outcomes have improved over time, with younger patients and lower baseline RDI achieving better results.
