Ménière's Disease: Current and Potential New Objective Measures Using Electrocochleography

The characteristic manifestations of Ménière's disease (MD) are mainly subjective, making MD difficult for physicians to diagnose without objective confirmation. A classic electrophysiologic technique for objective diagnosis of MD is electrocochleography (ECochG) to slow stimulus rates. This review will provide information regarding the sensitivity, specificity, and limitations of the conventional click and frequency specific ECochG measures. In addition, the paper will discuss two novel, promising techniques: fast click ECochG with the use of continuous loop averaging deconvolution (CLAD) and the auditory nerve overlapped waveform (ANOW). These new techniques may offer a new way in diagnosing MD through assessing neural adaptation and function of the apical half of the cochlear spiral.
