Changes in auditory pure tone threshold and speech discrimination and the phase and gain in the sinusoidal harmonic acceleration test were measured in subjects with endolymphatic hydrops (Meniere's disease) following the administration of glycerol. Although all subjects showed a marked improvement in auditory function, a comparable change in vestibular function, as measured by the sinusoidal harmonic acceleration test, was not observed.
