An absence of tinnitus.
We present and discuss a case of lifelong tinnitus in an otolaryngologist (L.D.L.) followed by complete elimination of the tinnitus as a result of a cerebral vascular accident located in the left corona radiata. Pre- and post-CVA audiograms showed no change in hearing. A magnetic resonance imaging study of the brain documents the size and location of the lesion. Discussion looks at recent studies of the central nervous system showing evidence of increased activity related to tinnitus. Our assessment of the lesion and the resulting loss of tinnitus can be explained by the neurophysiological model of tinnitus, which includes plasticity of the central nervous system.
