[Electrocochleography and the glycerol test in the diagnosis of Meniére's disease].

ECochG and glycerol test are two kinds of objective examinations for the diagnosis of Ménière's disease. Previous reports showed that the positive rates in both methods vary widely. In the present study, the incidence of abnormal SP enhancement was 63% (51 out of 81 ears in 70 patients). The SP enhancement correlated with the symptoms, especially aural fullness and high frequency hearing loss. The glycerol test was preformed in 25 patients (29 ears). The positive rate was 55.2%. There was a high positive rate of glycerol test in patients with low frequency and fluctuant hearing loss. Both examinations had a complementary effect in the diagnosis of Ménière's disease.
