An endolymphatic-mastoid shunt procedure was performed in 13 cases (14 ears) of MENIERE'S disease refractory to medical treatment. A postoperative follow-up of 1 to 5 years was done. 85% (11 cases) of these patients obtained a relief of vertigo. In 8 of these 11 cases, one to four small attacks within 6 months after shunt surgery were experienced. Hearing was improved in only 14.3% (2ears), unchanged in 28.6%, and became worse in 57.1%. In glycerol positive patients, postoperarive hearing was improved or stabilized. Tinnitus and ear fullness were unchanged in 60%. In accordance with AAOO 1972 criteria, there were 14.3% class A, 21.4% class B, 50% class C, and 14.3% class D results. Ideal result were obtained in class A and B patients (35.7%). Endolyphatic shunt surgery seems to be effective in the treatment of vertigo, and possibly improves or stabilizes hearing. The procedure is conservative and should be considered before destructive surgery for intractable cases of MENIERE'S disease.
