Eighteen patients with low tone perceptive deafness without vertigo, treated in our clinic during the last 7 years, were clinically studied. The audiometric criteria of the diagnosis were as follows: The total hearing level of the lower three frequencies was greater than100 dB and the higher three frequencies were less than 60dB, or the difference between the higher and lower sets of frequencies was more than 50dB. Patients were divided up into two groups; 10 cases of the non-recurrent type, and 8 cases of the recurrent type-the type considered to be Cochlear Meniere's disease. There were no definite differences in age, sex, subjective symptoms or the hearing level distribution between the two groups. The non-recurrent group demonstrated complete recovery in 4 cases, partial recovery in one case and no change in 4 cases. The condition of the tenth case could not be followed, and remained unknown. The recurrent group demonstrated complete recovery at various intervals between attacks, except in one case. This case developed into typical Meniere's disease. The relationship between low tone perceptive deafness and cochlear Meniere's disease in discussed.
