[Laryngo-tracheal injuries in hangings (apropos of 359 cases)].

Hanging is a relatively frequent method of suicide, and strangulation (accidental or volontary) may cause direct laryngeal or tracheal trauma and various lesions which may express themselves clinically either: -early, was severe from the start, e.g. fracture of the larynx, with major ventilatory distress, -or delayed, simple trauma without fracture, becoming manifest only after a few hours with severe dyspnea. In any case, early and late complications of these traumas require, even when they are apparently benign, admission to hospital on a specialised unit able to carry out rapidly respiratory intensive care.
