As of Feb. 1985, 87 cases of severe bilateral dysfunction of the labyrinth had been treated, 62 more than previous by reported. The age distribution of the onset of this disease was high in the fifth sixth and seventh decades and low in the fourth. The sex ratio was 1:1. In the previous medical history tuberclosis (SM) was present in 30-40%. The alleged cause of this disease was physical fatigue in 15%. The nature of the dizziness was repetition and floating in 60%, influenced by movements of the head or neck in about 60%. Tinnitus and deafness were present in 40% and 17% respectively. These findings suggest that in epidemiological studies of severe bilateral dysfunction of the labyrinth one must examine in detail the degree of hearing loss and clearly differentiate it from bilateral Ménières disease.
