A controversy exists concerning whether or not roentgenographic narrowing or nonvisualization of the vestibular aqueduct is a specific sign for Meniere's disease. Of 190 ears that were evaluated, abnormal aqueducts were seen in 42.9% of ears with Meniere's disease, 45.4% of contralateral, noninvolved ears from patients with Meniere's disease, 41.3% of ears with diseases other than Meniere's disease, 30.4% of ears with no disease, and 51.6% of normal ears. Narrowing or nonvisualization of the vestibular aqueduct is a nonspecific roentgenographic sign that is seen in diseased, as well as in normal ears, and should not be used to make a diagnosis of Meniere's disease. Indications for polytomography in Meniere's disease include (1) preoperative evaluation of the aqueduct prior to endolymphatic shunt procedures and (2) exclusion of acoustic neurinomas or other organic causes of vertigo.
关于前庭导水管的X线片狭窄或不显影是否为梅尼埃病的特异性体征存在争议。在接受评估的190只耳中，梅尼埃病患者的耳中42.9%出现导水管异常，梅尼埃病患者对侧未受累耳中45.4%出现导水管异常，非梅尼埃病患者的耳中41.3%出现导水管异常，无疾病的耳中30.4%出现导水管异常，正常耳中51.6%出现导水管异常。前庭导水管狭窄或不显影是一种非特异性的X线片体征，在患病耳和正常耳中均可见到，不应将其用于梅尼埃病的诊断。梅尼埃病体层摄影的适应证包括：（1）内淋巴分流术前对导水管进行术前评估；（2）排除听神经瘤或其他眩晕的器质性病因。
