[Drug-induced sleep endoscopy].

Drug-induced sleep endoscopy (DISE) is a procedure for the assessment of the upper airways in patients with obstructive sleep apnea (OSA) and was first described by Croft and Pringle in 1991 1. So far, it has not been clarified to what extent the DISE can be compared to natural sleep. Eastwood and colleagues ultimately described a correlation in terms of the tendency to collapse in sedation and during natural sleep.

Glottic visibility for laryngeal surgery: Tritube vs. microlaryngeal tube: A randomised controlled trial.

Background: Good visibility is essential for successful laryngeal surgery. A Tritube with outer diameter 4.4 mm, combined with flow-controlled ventilation (FCV), enables ventilation by active expiration with a sealed trachea and may improve laryngeal visibility.
