Electrocochleographic diagnosis.

The most characteristic electrocochleografic features of Menière's disease are a broad waveform, steep input-output curves, normal amplitude-latency relations and large summating potentials. The electrocochleografic data obtained in an individual case can be compared with the parameters of a reference set composed of a great number of patients with a well established diagnosis. For a new diagnostic case this leads with the aid of statistical methods and computer assistance to a probability diagnosis.
