Drug-induced sleep endoscopy (DISE) is used to visualize the upper airway collapse in patients with obstructive sleep apnea (OSA). The influence of the level of sedation on the obstruction pattern (OP) under DISE is not known. In this study, 43 male OSA patients underwent DISE with controlled application of propofol. Level of sedation was monitored with EEG. Significant changes in the OP were detected between light and medium levels of sedation. Surgical treatment options could be determined at medium sedation levels.
