Tinnitus Retraining Therapy (TRT) helps tinnitus patients by offering the possibility
of successful habituation of tinnitus-induced reactions and the habituation of tinnitus
perception. TRT presumably induces and sustains plastic changes in the neuronal networks
within the auditory system, and its connection with the limbic and autonomic nervous
systems, but it does not remove the tinnitus signal. Reports from a number of centers
around the world indicate high levels of effectiveness of this method. There is still
an ongoing discussion regarding TRT's efficacy and the relative contribution of its
components. This article attempts to summarize the basis of TRT and its foundations
on the neurophysiologic model of tinnitus. Additionally, some questions and concerns
related to the method are addressed.
