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.
这项研究有助于改进中枢听觉通路病变的听力学诊断，并试图通过比较15例患者的听力学和神经外科检查结果，将某些由脑肿瘤引起的听觉病变与具有拓扑诊断特征的听力学症状联系起来。通过7种普遍接受的测试方法对6例听神经瘤患者进行听力学检查，结果显示为迷路性而非中枢性症状表现；而4例桥小脑角肿瘤患者主要表现为中枢性听力缺陷，就检查结果的组合而言，这与3例脑桥肿瘤患者的中枢性听力缺陷明显不同。从听力学角度来看，2例侧脑室区域肿瘤患者仅表现出对侧双耳分听辨别能力缺失。
