CONCLUSION: 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.
OBJECTIVE: To visualize the detailed images of the VA using three-dimensional (3D) computed tomography (CT) and discuss its clinical utility in assessing MD.
SUBJECTS AND METHODS: 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.
RESULTS: 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.
