Introduction
Obstructive sleep apnea syndrome (OSAS) is a prevalent disorder
affecting 2% to 7% of U.S. adult population [1,2]. OSAS is
associated with cardiovascular, cognitive, stroke disorders, and death
[2,3]. The identification of the upper airway collapse site may be
performed by drug-induced sleep endoscopy (DISE), which provides useful
information for the treatment strategy [1]. The classical DISE
method involves the use of continuous propofol infusion in operating
room [1]. This approach is usually performed in ambulatory and
requires the patient monitoring after the anesthesia. In this
preliminary study, we assessed the feasibility, safety and patient
satisfaction of hypnosis-induced sleep endoscopy (HISE).
