Usually, tinnitus masking is accomplished by the use of a hearing aid which often is beneficial. Drug treatment consists of intravenous administration of antiarrhythmics (lidocaine), which can reduce tinnitus in some patients. Studies to date suggest that such therapy administered per os (oral) for a long time, brings no real benefit. Of the many drugs that have been tested through studies, oral antidepressants (nortriptyline 50 mg orally at bedtime) were found to be most effective. Drug treatment also includes vasodilators, benzodiazepines or other drugs indicated in migraine. The psychotherapeutic approaches are cognitive-behavioral therapy, relaxation, education, information, biofeedback, hypnotherapy. The combination of these therapeutic techniques for 3 months leads to a decrease in subjective perceived intensity noise, the patient giving a score at the beginning and end of the treatment.
