Background and Objectives:There is no single test that is definitive for making the diagnosis of Menieres disease. However, electrocochleography (ECoG) has been advocated as a reliable objective test for Menieres disease. This study was undertaken to asses the clinical characteristics among patients of Menieres diseases, who are divided into different groups, and the value of ECoG in establishing the diagnosis and clasification of Menieres disease. Materials and Method:From Jan 1990 to Dec 1999, 126 patients clinicaly suspected of unilateral Menieres disease and who had undergone ECoG were selected. Patients were classified into definite, probable and possible Menieres groups. The lowest audiological thresholds from the previous 6 months, the SP:AP ratio and the results of a caloric test were evaluated, retrospectively. Results:The definite Menieres group demonstrated an elevated SP:AP ratio among 74.4% of the cases, the probable Menieres group among 48.6%, and the possible group among 37.0%. However, symptoms such as tinnitus or earfullness showed no corelation betwen the groups. Acording to the audiologic evaluation, the posible group was mostly in the stage I, whereas the definite group and probable group were mostly in the stage III. The audiogram pattern and the caloric test showed no difference among the groups. Conclusion:diagnosis of definite Menieres group from probable or possible group. (Korean J Otolaryngol 2002;45:853-7)
