Introduction To overcome the limited readability of the conventional drug induced sleep endoscopy (DISE) system which only records flexible endoscopy images, we devised the Multimodality DISE System (MDS). MDS encompasses the monitoring systems for oxygen saturation, electrocardiogram, blood pressure, snoring intensity, and patient’s position. It enabled to record comprehensive situation of patients who underwent DISE. In this study, we compared the efficacy of MDS with that of the conventional DISE system. Methods and materials Ten patients underwent DISE at a tertiary hospital. DISE evaluated the airway of each patient in four positions; supine, supine with jaw thrust, right lateral decubitus, and left lateral decubitus. In addition, every examination was recorded by using both single monitoring system and MDS system. Five otolaryngologists interpreted the recorded examinations without knowledge of patient information (10 conventional DISE and 10 MDS). The visual analogue scale (VAS) scores for readability, reading times, ease of patient explanation and the ease of decision making were analyzed. Results Mean VAS scores for readability of conventional DISE and MDS were 4.41+2.56 and 8.42 +2.07 (p<0.001). Mean reading times for conventional DISE and MDS were 238.80+61.26 sec and 81.00+44.99 sec, respectively (p<0.001). MDS showed superiority in patient communication (p<0.001). MDS was helpful in decision making regarding patients with obstructive sleep apnea (p<0.001). Conclusions MDS enhanced the readability of previously recorded DISE and enabled easier doctor-patient communication. In addition, MDS is more effective in decision making regarding patients with OSA. MDS has laid the groundwork for separating the DISE prescriber from the DISE performer.
