The program of the 4th ESTS-Vienna Laryngotracheal course will cover a broad spectrum of airway-related topics. Basic principles of airway surgery will be adressed as well as highly specific challenges. Beyond surgical treatment options, innovations in the endoscopic treatment of airway diseases are highlighted during the symposium. Moreover, the interaction with the audience and active participation of the audience will be highly appreciated. On Saturday, a hands-on course on human cadavery will be offered to a limited number of participants for the very first time.
