Identifying the site of obstruction and the pattern of airway changes during sleep is essential to guide the treatment for obstructive sleep apnoea (OSA) in adults. The aim of the study was to evaluate whether drug-induced sleep endoscopy (DISE) helps to identify the site of obstruction in patients with OSA and whether DISE can find the reason for continuous positive airway pressure (CPAP) failure or intolerance.

66 patients with OSA (8 women, 58 men) were enrolled for this prospective observational study and indicated for DISE in the period from August 2015 to September 2016. The sites of obstruction in the upper airways were identified. The indications for surgery according to otorhinolaryngology examination before DISE and after DISE were compared. In 11 patients with severe OSA and/ or previously failed CPAP treatment, DISE with simultaneous CPAP (continuous positive airway pressure) was performed.

The most frequent multilevel collapse pattern was a combination of palatal, oropharyngeal, and base of tongue collapse (33.3%). A pathology of larynx (epiglottis) was observed in 21/ 66 (31.8%) patients. After DISE the surgical plan was changed in 44/ 66 (66.7%) of all patients. A pathology of epiglottis as a reason for CPAP failure was observed in 3/ 11 (27.3%) patients.

DISE helps to identify the site of obstruction of the upper airways in patients with OSA more accurately. The larynx plays an important role in OSA. Laryngeal obstruction can be a reason for intolerance of CPAP and failure of OSA surgery.

Key words:
drug-induced sleep endoscopy – obstructive sleep apnea – larynx – continuous positive airway pressure
