A Study of Vestibular Meniere's Disease

Abstract

I. Introduction
The present paper was designed to study the presence of vestibular Meniere's disease (VMD) and the possibility of VMD transforming into Meniere's Disease (MD).
II. Examinees and Methods
1) According to the diagnosis criteria set by the Department of the Otorhinolaryngology, Gifu University School of Medicine, a comparative study was made of the clinical features of 40 patients diagnosed as VMD and 80 diagnosed as MD.
2) Using the same criteria, a study was made of 50 patients diagnosed as MD, regarding the delay in the appearance of cochlear symptoms against the first attack of vertigo.
III. Results and Consideration
1) Of those diagnosed as VMD, females were predominant and a few had spontaneous nystagmus, CP and CP+DP, compared with those diagnosed as MD. These findings indicate the presence of VMD which differs from MD in the pathological change.
2) In MD, there existed cochlear symptoms developing after vertigo, the delay ranging from 2 months to 6 years. During that period, repeated attacks of vertigo occurred unaccompanied by cochlear symptoms. This shows the presence of VMD which shifts to MD.
3) In other words, it seemed that among patients of VMD there were one type which was similar to MD and another type differing from MD in pathology.
