An endoscopic procedure has been developed to enable constant monitoring of the mucous membrane of the larynx and trachea. The examination can be divided into four stages. 1. Transnasal inspection. 2. ⋯ A final check on the above-mentioned critical points during complete extubation after long-term intubation. Regular examination by this atraumatic method provides an early diagnosis of any mucosal damage caused by tubes. The recommendation that a secondary tracheotomy should be carried out after 48 h, and at the latest after a week, can no longer be supported, provided the necessary modern anaesthetic equipment and management is available.
