Abstract
Drug-induced sleep endoscopy (DISE) has been used in the last two decades in order to determine under fiberoptic visualization the exact site of upper airway collapse in obstructive sleep apnea patients. By directing surgical procedures towards obstruction-specific structures, surgical outcomes improve. Additionally, with the help of passive maneuvers, the potential efficacy of mandibular repositioning devices can be estimated. The shared use of the VOTE classification for the assessment of DISE can facilitate its scientific evaluation in individual centers and also the collection of data across multiple centers. Head rotation during DISE improves upper airway collapse. This improvement is predominantly seen in positional obstructive sleep apnea patients. In addition, there is no difference in upper airway collapse between right and left head rotation and also no difference between rotation of the head and lateral positions. We recommend that in positional patients, DISE should be performed in supine and lateral positions.
