In 1934, Loré1 called attention to the latter type of hypertrophic laryngitis. In addition to observations made in experimental work on animals, he recorded the results obtained in 4 patients by stripping off the mucous membrane of the hypertrophic vocal cord.

The etiologic factor would seem to be trauma to the cords by habitual misuse of the larynx, by repeated acute infection or by a combination of these. In our series of 8 cases one or both of these conditions were present. Three patients worked in a noisy environment in which it was necessary for them to shout in
