Tinnitus retraining therapy (TRT) focuses on the behavioral retraining of the associations induced by tinnitus perception and on inducing and further facilitating the process of habituation of tinnitus perception. This study comprised 137 tinnitus patients: groups I, II & III representing TRT categories 0, 1 & 2 and group IV receiving medication. The Tinnitus Handicap Inventory was used for scoring. A pre- and post-treatment score difference of at least 20 points revealed effectiveness of TRT compared to medical treatment but was not revealed if the patient changed to a less severe handicap with a score difference of 18.56 ± 10.48. Accordingly, comparing the results with other studies is difficult due to the non-standardized scoring of the real improvement as well as the different questionnaires used. The patient’s age, gender, site, course and duration of tinnitus did not affect the results of treatment.
