Abstract
A 71-year-old male with severe obstructive sleep apnea and nasal septal deviation presented to a positive airway pressure (PAP) alternatives clinic due to persistent obstructive events on both continuous PAP and bilevel PAP therapy delivered via oronasal mask. He underwent drug-induced sleep endoscopy with PAP titration to determine the mechanism of oronasal mask failure. A nasal mask was also applied and titrated for comparison. Drug-induced sleep endoscopy with PAP showed tongue base collapse which resolved at low pressure using a nasal mask. Application of an oronasal mask increased minimum therapeutic PAP level. Tightening the mask worsened tongue base collapse, which was not resolved by increasing the PAP level. Following nasal surgery, the patient was able to tolerate nasal continuous PAP at low therapeutic pressure, which resulted in both objective and self-reported improvement is his obstructive sleep apnea. This case highlights the ability of drug-induced sleep endoscopy with PAP to determine the mechanistic cause of oronasal mask failure.

期刊介绍:
Journal of Clinical Sleep Medicine focuses on clinical sleep medicine. Its emphasis is publication of papers with direct applicability and/or relevance to the clinical practice of sleep medicine. This includes clinical trials, clinical reviews, clinical commentary and debate, medical economic/practice perspectives, case series and novel/interesting case reports. In addition, the journal will publish proceedings from conferences, workshops and symposia sponsored by the American Academy of Sleep Medicine or other organizations related to improving the practice of sleep medicine.
