In 1976-1978 there were 15 children hospitalized in the Children's ORL Clinics in Prague and treated for larynx trauma caused by long-term endotracheal intubation. Tracheostomy was performed in all cases, the changes in the larynx were mostly treated in a conservative manner. In one instance we used laryngofissura; however, further dilatations had to be carried out. With a single exception, all the patients have been healed successfully. Plastic operations were performed to make decannulation easier.
