Labyrinthine Symptomatology of VestibularSchwannomas

In a group of 125 operated patients with a unilateral vestibular schwannoma in 22,i.e. 17.6% the disease was manifested by acute cochleovestibular symptomatology, atypical fora tumour. The authors discuss possible reasons ensuing from pathological anatomical and pathophysiological findings. These findings of initial acute manifestations of the tumour, in extremecases very similar to Méniere’s disease or frequently also by coincidence of the coc hlear andretrocochlear component of hypacusia with a slow course of the disease must be therefore considered in the differential diagnosis. For early diagnosis which is decisive for the extend and severityof the postoperative morbidity the surgeon must select sufficiently sensitive diagnostic tests.

Key words:
vestibular schwannoma, cochlear symptomatology.
