title: Tinnitus remission objectified by neuromagnetic measurements.
abstract: In a previous paper of ours (Hoke et al., 1989a) the hypothesis was put forward that the amplitude ratio of the two major waves of the auditory evoked magnetic field (AEF), M200/M100, is an objective measure which allows to discriminate between individuals suffering from tinnitus (ratio less than 0.5) and individuals without tinnitus (ratio greater than 0.5). We have now been able to trace the process of tinnitus remission in one exemplary case during a period of 256 days after acute onset of tinnitus (due to a noise trauma), in which the amplitude ratio recovered from 0 to a normal value of approximately 1. This very first objectification of tinnitus remission strongly supports our hypothesis and indicates that AEF may become an indispensable, invaluable tool in both tinnitus research and management.
