Radiographic visualization of the vestibular aqueduct (VA) from a lateral inside view was effective in assessing patients with Meniere's disease (MD). There were no VA shapes specific to MD on radiography, except for an obliterated VA. This technique could yield more accurate images and functional assessment of the VA for MD evaluation in a clinically useful and convenient manner, without requiring morphologic measurement.
To visualize the detailed images of the VA using three-dimensional (3D) computed tomography (CT) and discuss its clinical utility in assessing MD.
The VAs in 13 healthy subjects and 25 MD patients, who were definitely diagnosed according to criteria described by the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head and Neck Surgery (AAO-HNS), were imaged from the medial and lateral sides using 3DCT and compared to conventional CT images.
Examination of the VA from both the lateral outside and inside views on 3DCT yielded more precise images than generated by conventional CT and could be useful to estimate the VA function. The estimated VA function in the MD ears was significantly abnormal compared to the function in healthy ears. An obliterated VA was characteristic of affected MD ears.
从前庭导水管（VA）的外侧内视图进行影像学观察，对于梅尼埃病（MD）患者的评估是有效的。除了VA闭塞外，MD在影像学上没有特定的VA形态。该技术可以以临床有用且方便的方式，对VA产生更准确的图像和功能评估，而无需进行形态学测量。
使用三维（3D）计算机断层扫描（CT）观察VA的详细图像，并讨论其在评估MD中的临床应用。
根据美国耳鼻咽喉头颈外科学会（AAO-HNS）听力与平衡委员会描述的标准确诊的13名健康受试者和25名MD患者，使用3DCT从内侧和外侧对VA进行成像，并与传统CT图像进行比较。
3DCT上从前庭导水管的外侧外视图和内侧内视图进行检查，比传统CT产生的图像更精确，并且有助于评估VA功能。与健康耳朵相比，MD耳朵的VA功能估计明显异常。VA闭塞是受影响的MD耳朵的特征。
