Reports in the literature suggest that patients with otosclerosis, neural lesions such as acoustic neuroma, pontine lesions, and temporal lobe lesions may show abnormal sound localization ability. In the present experiment, 15 normal subjects and 22 patients with various auditory pathway lesions had sound localization testing using special apparatus. The results confirmed that patients with otosclerosis were unable to localize low frequency sounds. Those with temporal lobe lesions made judgments not significantly different from normal subjects. Patients with unilateral sensorineural deafness made errors localizing high frequency sounds. Those with acoustic neuromas made greater errors than those without, but the difference between these two groups just failed to reach statistical significance. The number of cases was however small, and further studies are in progress to attempt to define numerical criteria to assist clinical decisions with regard to the selection of patients for invasive investigations such as oil cisternogram.
文献报道表明，患有耳硬化症、神经病变（如听神经瘤、脑桥病变和颞叶病变）的患者可能表现出异常的声音定位能力。在本实验中，15名正常受试者和22名患有各种听觉通路病变的患者使用特殊仪器进行了声音定位测试。结果证实，耳硬化症患者无法定位低频声音。颞叶病变患者做出的判断与正常受试者无显著差异。单侧感音神经性耳聋患者在定位高频声音时出现错误。患有听神经瘤的患者比未患听神经瘤的患者错误更多，但这两组之间的差异刚刚未达到统计学显著性。然而，病例数量较少，目前正在进行进一步研究，试图确定数值标准，以协助临床决定选择患者进行诸如脑池造影等侵入性检查。
