Upper airway surgery to rescue the "untitratable" patient with OSA and obesity.

This is a case report of an 41-year-old male with obesity (body mass index 90 kg/m²), severe obstructive sleep apnea (OSA), and an apnea-hypopnea index of 90 events/h despite high bilevel positive airway pressure (BPAP). He presented to the PAP Alternatives Clinic and underwent tonsillectomy, expansion sphincter pharyngoplasty, and partial uvulectomy to improve positive airway pressure effectiveness. Postoperative BPAP retitration resolved the patient's OSA. The patient is currently using BPAP therapy at home with improvement in both objective and self-reported OSA outcomes.
