[The role of the glycerol test for diagnosis and treatment of Menière disease (author's transl)].

60 patients--25 with different hearing losses and 35 with Menière disease--underwent the glycerol test. It was demonstrated that only the group with endolymphatic hydrops showed in about 60% a positive test result. The meaning of the glycerol test for differential diagnosis of Menière disease from other diseases with attack vertigo is discussed and the role to select the patients for endolymphatic sac surgery is emphasized.
