Tinnitus Retraining Therapy (TRT): outcomes after one-year treatment.

The aim of the study is to present our results regarding the efficacy of TRT for tinnitus relief in patients with clinically significant tinnitus compared to a group treated with vasoactive agents. In a nonrandomized prospective study, 63 patients with disabling tinnitus were recruited. Greek translation of the Tinnitus Handicap Inventory (THI) and visual analogue scale (VAS) for annoyance caused by tinnitus when conducting four major activities of everyday life (work, sleep, relaxation and concentration) were examined in a 12-month period. The THI score was significantly improved in the TRT group, as well as mean VAS scores, in all measures. Comparison of the mean improvement of THI and VAS scores after treatment showed significant differences between the two groups, favoring TRT treatment. Our data suggest that TRT is an effective treatment. It reduces the level of annoyance induced by tinnitus and improves the ability of patients to work, sleep, relax or be concentrated.
