DISE with CPAP: a useful procedure to evaluate upper airway collapsibility.

Purpose: Drug-induced sleep endoscopy (DISE) is commonly performed in patients suffering obstructive sleep apnea (OSA) with continuous positive airway pressure (CPAP) intolerance. We aimed to evaluate the effects of adding CPAP to DISE to provide understanding of the reason of its failure and better guidance in future therapeutic decisions.

Methods: A retrospective observational descriptive study was conducted on CPAP-intolerant patients with moderate-severe OSA.
