Effects of tinnitus retraining therapy (TRT) for patients with tinnitus and subjective hearing loss versus tinnitus only.

The patients with tinnitus and/or hyperacusis undergoing an 18-24 month period of TRT are divided into five categories of treatment. Different types of counselling and sound therapy are used in each category. Selection of patients into a specific category depends on such factors as: hyperacusis, subjective hearing loss and long-lasting effect of noise on tinnitus. The 108 cases were evaluated After 1 year of treatment. The results of therapy of 40 patients with tinnitus and subjective hearing loss (category II) were compared with the results of therapy of patients with tinnitus only (categories 0 and I). A special questionnaire, answered before and during the treatment, was used to assess the results. Our data indicate significant improvement in about 70% of patients with tinnitus only and in about 90% of patients with tinnitus and subjective hearing loss after one year of therapy.
