Inclusion criteria included adults &gt;\u200918\u2009years of age with a diagnosis of obstructive sleep apnea with an Apnea\u2013Hypopnea Index (AHI) &gt;\u200915, a body mass index (BMI) &lt;\u200932, and &lt;\u200925% central apneas on polysomnography. Twelve patients with complete circumferential collapse underwent a modified palatopharyngoplasty. Postoperatively, a repeat sleep study was performed. A repeat DISE was recommended for those with incomplete surgical response (clinically and\/or AHI).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twelve patients with complete circumferential collapse were eligible for the study. Mean BMI was 30.5. Mean preoperative AHI was 54.0 events per hour. Following a modified palatopharyngoplasty, the mean AHI was reduced to 33.1 events per hour, and 100% (12 of 12) of the patients converted from a pattern of complete circumferential collapse to either no collapse at the level of the velum (3) or an anteroposterior pattern of collapse (9).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We demonstrate that a modified palatopharyngoplasty can successfully convert collapse patterns in patients with complete circumferential collapse.
