Morphological characteristics of vestibular aqueduct associated with occurrence of Meniere disease: Study

The correlations between VA morphology and the degrees of hearing loss and endolymphatic hydrops (EH) were also analyzed. Results: VA was classified as grades 1–3 in 11, 17, and 12 ears in the MD group and 5, 26, and 37 ears in the control group, respectively. The patency differed significantly between the groups (p < 0.01). The width of the outer orifice and length of VA were significantly smaller in the MD group than those in the control group (p < 0.05). Both VA patency and length were correlated with the degree of EH in the cochlea and the vestibule (p < 0.05). No difference was found between VA morphology and the degree of hearing loss (p > 0.05). The morphological characteristics of VA were found to be associated with the occurrence of MD and the degree of EH.
