[Laryngeal lesions after prolonged intubation. Anatomo-pathologic study].

Laryngeal lesions produced during prolonged intubation were studied in 11 larynxes from consecutive patients dying during intensive care. A constant finding was ulceration of the vocal process, combined in 7 cases with inter- or pre-arytenoidal subglottic ulcerations. Histology failed to reveal signs of lesions of the cricoarytenoid joint or chondritis of the posterior arch of the cricoid cartilage.
