Glycerol test for endolymphatic hydrops was erformed in 36 patients with Meniere's disease.1) Various criteria have been used for evaluate he amount of hearing improvement as a “positive” lycerol test. We used a 20 or 30dB improvement s the limit (total amount of hearing improvement t all frequencies from 250Hz to 4kHz). The 20 B improvement was thought to be satisfactory and mple to use as a criterion for improvement.2) The glycerol test was positive in about 50% the cases of Meniere's disease.3) The glycerol test was diagnostic in 78% of e patients with Meniere's disease during verti nous attacks and significant hearing loss.
