Drug-Induced Sleep Endoscopy Upper Airway Collapse Patterns and Maxillomandibular Advancement.

Objectives/hypothesis: To evaluate upper airway (UA) collapse patterns during drug-induced sleep endoscopy (DISE) and maxillomandibular advancement (MMA) surgery outcome, paying particular attention to the DISE phenotype complete concentric collapse at the level of the palate (CCCp).

Study Design: Prospective case series.

Methods: Nineteen patients diagnosed with obstructive sleep apnea (OSA) prospectively underwent mandibular advancement device (MAD) treatment followed by MMA surgery.
