title: [Audiological findings in cases of acoustic neuromas, cerebellopontine angle and brain tumors (author's transl)].
abstract: The study contributes to improve, audiological diagnostics of central auditory path lesions and attempts, through the comparison of audiological and neurosurgical findings of 15 patients, to refer certain auditory lesions caused by cerebral tumors to topodiagnostically characteristic audiological symptoms. The audiological findings obtained through 7 generally accepted test methods from 6 patients with an acusticus neurinoma indicate a labyrinthine but not a central symptomatic picture while 4 patients with a pontine-angle tumor present a chiefly central hearing defect which, as regards the constellation of findings, clearly differs from the central hearing defect of 3 patients with a pontine tumor. Two patients with tumors in the lateral ventricle area merely show, from the audiological point of view, a lack of contralateral dichotic discrimination.
