ABSTRACT
OBJECTIVE@#To probe the factors that affect the pure-tone threshold glycerol test and the distribution of frequencies in positive glycerol test.@*METHOD@#We tested the pure-tone threshold before and after glycerol intake in patients with Meniere's disease, and then analyzed the positive rates,distribution of positive frequencies and the time when the maximum threshold changes appeared.@*RESULT@#The positive rate of pure-tone glycerol test was 72.09%, of which the threshold descending rate was 47.67%, and the threshold rebounding rate was 24.42%; the pure-tone threshold changes of descending group and rebounding group were (17.41 +/- 9.92) dB, (13.53 +/- 4.64) dB respectively, and the differences were significant. The distribution of positive frequencies were 250 Hz, 125 Hz, 500 Hz, 1 kHz, 4 kHz, 2 kHz, 8 kHz in descending order. The maximum pure-tone threshold changes mostly appeared within 2 or 3 hours after glycerol intake.@*CONCLUSIONS@#Patient selection, test occasion and the judgement criteria may affect the positive rate of glycerol test; the positive frequencies distribute in the low-frequency region mainly; the maximum pure-tone threshold changes mostly appeared within 2 or 3 hours after glycerol intake.
