Abstract
In 5 patients presenting the Tullio phenomenon, out of a casuistry of 6,000 patients, auditive and vestibularis functions are studied, in particular the electronystagmo- graphic pattern. This is in the hope of eventually finding a common pattern of these rare cases where the auditives stimuli affect on the posterior labyrinth could be objected. The results are not incompatible with the hypothesis drawn from the histopathologic work of McCABE and Lawrence [1958] and the neurophysiologic work of Burgeat et al. [1966]; the peripheral lesions would, in fact, be limited to a single sacculus, where as the central level of the vestibularis pathways of the cerebellum would be electively stimulated. This same etiopathogeny could render the destroying effect of noises on the posterior labyrinth without the Tullio phenomenon. A clinical example of this is mentioned.
