[Laryngeal and tracheal stenoses following prolonged intubation and tracheotomy].

Within 15 years we observed 8 stenoses following longtime intubation and tracheostomy (1.87% of all patients who underwent longtime-intubation and 1.11% of all patients following tracheostomy). The stenoses were diagnosed between 4 weeks and 6 months after removal of the device. The primary disease, especially shock, is more important for the development of stenoses than the duration of intubation.
