An endolymphatic sac-mastoid shunt procedure was performed in 37 cases of Meniere's disease. In accordance with AAOO (American Academy of Ophthalmology and Otolaryngology,1972) criteria,19% were class A,54% class B,15% class C,12% class D. Hearing losses of more than 15 dB occurred in 50% of the ears in which silicon film was used, and 23% of those whose sacs were incised and turned over by Kitahara's method. There was a statistically significant difference in the incidence between the two groups.
