To diagnose the hydrops of the labyrinth in Meniere's disease, a glycerol test is used, but not in all cases the glycerol test is positive.
Glycerol test can be negative in the irreversible stage of endolymphatic hydrops due to morphological changes and in reversible if there is no excess fluid at the time of the study. We set ourselves the goal of evaluating the glycerol test based on the results of a study of the auditory and vestibular functions of patients with Meniere's disease. The study included 72 patients with Menier's pain, aged from 26 to 69 years. According to the data of tone audiometry, a positive glycerol test was detected in 72.5% of cases, which can only be used to establish fluctuations of the cochlear function where it is more informative and dynamic.

The course of Meniere’s disease is observed in every second patient and even more often. Despite the high frequency of monosymptomatic development of the disease, many authors regarded this as an atypical course of Meniere’s disease and even distinguished its cochlear and vestibular forms. In our opinion, no convincing arguments in favor of this point of view are given. 52 people were examined who underwent otorhinolaryngological examination, detailed audiometric and vestibulometric examination. In each of the examined groups of patients, a decrease in excitability on the side of the lesion was the most typical reaction of the vestibular system to the hydrops of the labyrinth.
