Galvanic testing in neuro-otological diagnostics.

From 1980 to 1986, a total of 436 patients were investigated by galvanic testing. Pathological findings resulted in 45 (out of 54) patients with a suspect tumour of the cerebellopontine angle (CPA), 7 (out of 7) patients with a Herpes zoster infection, 25 (out of 32) patients with an isolated, unilateral loss of vestibular function, 4 (out of 14) patients with head injuries. No pathological results of galvanic testing were found in patients with sudden deafness, Meniere's disease, vertebrobasilar or cerebrovascular insufficiency, etc.
