Otosclerosis associated with Ménière's disease: a histological study.

A histological study of a pair of temporal bones was performed in a case of Menière's disease. A severe endolymphatic hydrops and extensive capsular otosclerosis bilaterally was found. Severe endolympathic hydrops results from otosclerotic endolympahtic duct occlusion. Our unique histopathological findings show that a causal association exists between these two entities.
