UA Collapse Patterns in Drug-Induced Sleep Endoscopy

UA Collapse Patterns in Drug-Induced Sleep Endoscopy

What upper airway (UA) collapse patterns can be seen during drug-induced sleep endoscopy (DISE), and how do they compare with baseline patient characteristics?

Background: Sleep-disordered breathing (SDB) ranges from snoring to obstructive sleep apnea (OSA). The goals for UA evaluation are to improve treatment success rates by selecting the most appropriate therapeutic option for individual patients and to examine the complex pathophysiology of UA collapse in OSA. During sleep nasendoscopy or DISE, UA collapse patterns can be assessed when alternatives to continuous positive airway pressure (CPAP) treatment are being considered.

Study design: Observational study of 1,249 patients who underwent polysomnography and DISE.

Setting: Antwerp University Hospital, Antwerp, Belgium.
