Abstract
To investigate the relationship between endolymphatic hydrops and otitis media, 34 patients with Meniere's disease and 26 patients with chronic otitis media received the glycerol test and electrocochleography.
1. It is desirable to examine mild endolymphatic hydrops not only with the glycerol test but also with electrocochleography.
2. Endolymphatic hydrops was found in 12% of the patients with chronic otitis media. Unlike Meniere's disease, this hydrops seems to be reversible in nature.
3. Active chronic otitis media, with auricular symptoms and pathological changes in the middle ear cavity, tended to be more frequently complicated by endolymphatic hydrops.
