Results of Endolymphatic Sac Decompression (Kitahara) for Meniére's Disease

Thirty patients with Meniere's disease were treated with endolymphatic sac decompression (Kitahara ; 1974) from April 1986 to October 1989. Ten of them have been followed clinically for two years ; In 10 % of the patient complete control of definite attacks was achieved, and in 90 % substantial control. Hearing improvement at least 10 dB was noted in 20 %, but hearing remained unchanged in 70 % and became worse in 10 %. We considered these results to be satisfactory, and we conclude that epidural shunt operations are useful in controlling vertigo and also in preservating of hearing in patients with Meniere's disease.
