Abstract
The author presents the first results observed after ultrasonic irradiation at low intensity in a group of patients suffering from Menière's disease and other types of labyrinthosis. (1) Round window irradiation seems to be indicated by cases of severe deafness accompanied by very troublesome tinnitus, depending not only on Menière's disease, but also on cochlear dropsical lesions, sudden deafness of vascular origin. (2) Oval window irradiation seems to be indicated by Menière's disease in which hearing ought to be preserved.
