Filipo R, Cordier A, Barbara M, Bertoli GA. Electrocochleographic findings: Meniere's disease versus sudden sensorineural hearing loss.Electrocochleography was conducted in 185 patients with Meniere's disease and 117 with sudden deafness. Electrophysiological findings from the two groups were compared in order to identify pathogenic similarities between the two conditions. Parameters investigated were the summating potential (SP)/action potential (AP) ratio, audiometric profiles and audiometric changes after medical therapy. A high SP/AP ratio was found in the patients with sudden deafness, thus supporting a possible hydropic aetiology in this group. In conclusion, electrocochleography can be considered a useful technique as it permits identification of an hydropic condition in certain cases of sudden deafness.
