[Computed tomographic findings of the development of the bone around the vestibular aqueduct in Meniere's disease].
OBJECTIVE
To study the development of the bone around the vestibular aqueduct (VA) in Meniere's disease (MD) by CT.


METHODS
The experiment consisted of three groups; normal ear group, non-MD vertigo group and MD group. VA in each group was examined by CT, and the minimum distance between the posterior semicircular canal and the posterior petrous surface where contain the endolymphatic sac.


RESULTS
VA visualization rate in MD was low, P-P distance in MD group was shorter than that of normal ear group and non-MD vertigo group.


CONCLUSIONS
It is the fundamental pathological anatomy in MD that VA and the bone around VA are maldeveloped.
