[Electric response audiometry (brainstem potentials, late auditory potential N1): observations at patients suffering...

At some patients suffering from Menière's disease or sudden hearing loss the late auditory potential N1 and the brainstem potentials were registered. It could be shown, that an exact differential diagnosis between these both illnesses was not possible by means of these acoustically evoked potentials. A statistical analysis of the measured values of the brainstem potential IV ascertained this statement. Furthermore it was not possible by means of these potential to predict an improvement of hearing at patients with sudden hearing loss. Finally the potentials showed an increasing of their latencies which was greater at patients with sudden hearing loss than at patients with Menière's disease.
