RESUMO
28 patients were treated with soft-laser therapy. Two-thirds of them had suffered from tinnitus for more than six months and had undergone different therapies before. Each patient was treated twelve times, treatment lasting ten minutes. Before therapy six ml of Tebonin were given i.v. Four minutes later, the laser was positioned at a distance of one centimetre from the patients' mastoid. The laser beam was directed two fingers above the mastoid tip aiming at the lateral wall of the contralateral orbit. Before and three weeks after treatment each patient underwent pure tone audiometry and determination of the tinnitus intensity. Patients were asked to score symptoms before and three weeks after therapy. Hearing levels before and after soft-laser therapy did not show any statistic difference. Three weeks after the last treatment, twenty patients denied any change in tinnitus. Two patients felt an improvement of tinnitus and one patient had recovered completely. Five patients remained undecided about the outcome of therapy. To sum up, according to our results, the trial so far failed to show clear benefits of soft-laser therapy for patients suffering from chronic tinnitus.
