Comparison of conventional continuous positive airway pressure to continuous positive airway pressure titration performed with sleep endoscopy.

Objectives/hypothesis: To evaluate the effect and obtain a pressure value of continuous positive airway pressure (CPAP) under direct visualization using drug-induced sleep endoscopy (DISE) and compare the pressure values with values obtained using conventional CPAP.

Study Design: Prospective, double-blinded, cohort study.

Methods: Sixteen patients with obstructive sleep apnea syndrome (OSAS) were included in the study.
