Meniere's disease is represented by episodic vertigo (vestibular symptom), tinnitis and hearing loss (cochlear symptom). It is possible to devide patients with Meniere's disease into three groups; those with cochlear and vestibular symptoms starting at the same time, and those with the vestibular symptoms starting before or after cochlear symptoms: In this presentation, we studied the clinical differences of these three groups. The following results were obtained.1. In the case of cochlear Meniere's disease, the cochlear symptom is slight and it is easy to acquire the vestibular symptom. The cause of cochlear Meniere's disease was considered to be the existence of endolymphatic hydrops. Compared with frequency of bilateral Meniere's disease, bilateral cochlear Meniere's disease was more found.2. In the case of vestibular Meniere's disease, the vestibular symptom is slight and it is difficult to acquire the cochlear symptom. The cause of vestibular Meniere's disease, in all cases was not considered to be the existence of endolymphatic hydrops.3. In the case of Meniere's disease with vestibular symptoms starting after the cochlear symptoms, both the vestibular symptoms and cochlear symptoms are heavy. In the case of Meniere's disease with vestibular symptoms starting before the cochlear symptoms, both symptoms are slight.

Recent advances in imaging technique, including high resolution thin section computed tomography scanning and magnetic resonance imaging (MRI), permit the easy diagnosis of congenital malformations of the osseous labyrinth, which have so far been lumped together as "Mondini dysplasia". In the present study the anatomic patterns from the radiographic appearance and the clinical manifestation were examined in 18 patients (23 ears) with radiographic abnormalities of the inner ear. The most common abnormal configuration was a large vestibule (20 of 23 ears). This anomaly of the vestibule often involved the lateral semicircular canal, revealed as a round high signal zone on T2-weighted MRI. However, a large vestibule was not always associated with an abnormal cochlea. Abnormal cochleas were found in 8 of the 20 ears with a large vestibule, and most of these 8 ears had total or profound deafness. But 4 of the 10 ears with residual hearing had low tone deafness and 6 had fluctuating hearing loss, which was frequently associated with attacks of dizziness. These clinical manifestations of Mondini dysplasia are similar to those of patients with endolymphatic hydrops.
