Auditory test results in the first 53 causes of this series of 500 acoustic neuromas were reported in 1964. Subsequent studies involving larger numbers of patients detailed new results based on these additional cases. Five hundred cases of surgically confirmed acoustic neuromas were analyzed. Pure-tone loss configurations, speech discrimination, auditory adaptation as measured by the modified tone decay test, Bekesy audiometry, short increment sensitivity index test, and alternate binaural loudness balance test data were evaluated. The results of this investigation in general confirm previous studies, although percentage figures for positive tests differed in the large series. Acoustic reflex results were reported for those patients evaluated more recently. Slightly more than half of the cases had inconsistent audiometric results in one or more aspects. Inconsistencies to the tests were examined in detail. Consistent responses to the tests appear to be related to the size of the lesion. The full battery of audiologic tests is of importance in the differential diagnosis of acoustic neuromas.
1964年报告了该系列500例听神经瘤中前53例的听力测试结果。随后涉及更多患者的研究基于这些新增病例详细阐述了新的结果。对500例经手术证实的听神经瘤进行了分析。评估了纯音听力损失曲线、言语辨别、通过改良音衰试验测量的听觉适应、Bekesy听力测验、短增量敏感指数测试以及双耳交替响度平衡测试数据。尽管在大量病例中阳性测试的百分比数据有所不同，但本研究结果总体上证实了先前的研究。报告了最近接受评估的患者的听觉反射结果。略多于一半的病例在一个或多个方面存在听力测试结果不一致的情况。对测试中的不一致情况进行了详细检查。测试的一致反应似乎与病变大小有关。全套听力测试在听神经瘤的鉴别诊断中具有重要意义。
