EVestG™: A measure for Meniere´s Disease

Meniere´s Disease is commonly diagnosed using Electrocochleography (ECOG). EVestG is a variant of ECOG utilizing one or more patient tilts as stimuli in place of the ECOG´s repeated tonal clicks. The dynamic measures averaged “background-onAA” (onAA=acceleration phase of tilt) and background-onBB (onBB=deceleration phase of tilt) of excitatory (ipsilateral tilt) vestibular responses are compared for a small group of age matched Controls (n=18) and Meniere´s Disease patients (n=11). Preliminary data provides for an apparent clearer demarcation between Controls and Meniere´s patients. Meniere´s patients appear to show not only increased Sp/Ap ratios but also a decreased dynamic range of response as measured by the EVestG response measure averaged “background-onBB”. Increased sample size is required to validate these findings.
