[Etiology of laryngotracheal stenoses in the adult].

Laryngotracheal stenosis in 145 adults was the direct result of laryngeal lesions in 27 cases and of iatrogenic etiology in 118. External injury was at the origin of most of the direct cases, the resulting complex anatomical lesions being treated with difficulty and having a very poor prognosis. Lesions of an indirect origin were principally sequelae from intensive care, their analysis and treatment being more easily systematized.
