Multidirectional and computerized tomography of the vestibular aqueduct in Meniere's disease.

Multidirectional and computerized tomography have been used for the radiographic assessment of the vestibular aqueduct in Meniere's disease. The results of studies performed by us and/or other authors indicate that there is a statistically significant difference in the size of the vestibular aqueduct between the Meniere's and control groups (in Meniere's disease the vestibular aqueduct is often narrowed or obliterated); and that periaqueductal pneumatization is often decreased or absent in ears affected by Meniere's disease. Recent histological studies performed on temporal bones of patients with Meniere's disease have confirmed these radiographic observations.
