[The apoplexy of the labyrinth (author's transl)].

Owing to the morphological, physiological and pathophysiological similarities in the vasculature of the brain and the inner ear, the term apoplexy can also be applied to the inner ear. The apoplexy of the labyrinth is defined as an acute and severe panlabyrinthic disturbance with sudden hearing loss or deafness in association with vestibular functional disorders. The apoplexy may occur after hemorrhage as a result of inner ear blood vessel ruptures or after malacias following localised ischemias just as it occurs in the brain. Treatment of such cases were carried out by application of high doses of cortison. The prognosis of these inner ear disturbances is unfavourable.
