Tomography of the vestibular aquaeduct was carried out in patients with Ménière's disease, patients with chronic otitis and in patients without ear disorders. Visualization of the vestibular aquaeduct was evaluated blindly. The descending part of the aquaeduct was clearly visible in 95% of patients without ear disease. In the other groups, including contralateral non-affected ears in Ménière patients, the aquaeduct was clearly visible in only about 50%. The incidence of narrow or invisible aquaeducts in ducts in Ménière patients and in patients with chronic otitis was essentially the same. This radiologic finding seems to be an unspecific sign, present possibly in a variety of ear disorders.
对梅尼埃病患者、慢性中耳炎患者以及无耳部疾病的患者进行了前庭导水管的断层扫描。对前庭导水管的显影进行了盲法评估。在95%无耳部疾病的患者中，导水管的下降部分清晰可见。在其他组中，包括梅尼埃病患者对侧未受影响的耳朵，导水管仅在约50%的患者中清晰可见。梅尼埃病患者和慢性中耳炎患者中导水管狭窄或不可见的发生率基本相同。这一放射学发现似乎是一个非特异性征象，可能存在于多种耳部疾病中。
