Comparison of 3 Methods to Diagnose Endolymphatic Hydrops in Meniere's Disease

The aim of this study is to compare 3 methods for the diagnosis of endolymphatic hydrops (EH) in patients with Meniere's disease: MRI 3 Tesla (to visualise EH directly), and functional explorations, namely electrocochleography and dephasing of acoustic distortion products (which are modified by the EH). The research hypothesis is that the examinations will show agreement in the diagnosis of EH, and that the results obtained (quantitative values) will vary in the same direction over time and during flares of MD.
