22 patients presenting unmistakable symptoms of Ménière's disease including two bilateral cases, among whom a glycerol test and an electrocochleography were carried out on 24 ears. 13 out of 24 cases, i. e. 54%, turned out positive to the glycerol test, and 17 out of 24 cases, i. e. 71%, gave 0.5 or more in the electrocochleography's -SP/AP. Among those who were tested in a period close to a vertigo attack, the positive ratio was slightly higher in both tests: the former being 60% and the latter 84%. However, no correlation was observed between the results.When positive and negative groups are compared in the glycerol test results, in the positive group the majority showed large values in the -SP/AP in the vicinity of 1.0; while in the negative group, many showed fairly small values contained between 0.5 and 0.8.Based upon these results, we presume that an active endolymphatic hydrops is reflected by large -SP/AP in the vicinity of 1.0, and the increase of these specially large -SP/AP may turn out to be as significant as the positive group in the glycerol test.
