In patients scheduled for surgery and anaesthesia in the Head-/neck/ear/nose/throat -region the investigators compare the ease of tracheal intubation between a new ultra-thin endotracheal tube, Tritube, and a standard endotracheal tube in patients with predictors of difficult laryngoscopy. The intubation is performed with an angulated video laryngoscope.~Furthermore the investigators compare the acceptance of leaving the Tritube in trachea after end of anaesthesia, with the use of a tube exchange catheter. The latter continues into the post-operative recovery-ward.
