Title

LOW-LEVEL LASER FOR TREATMENT OF TINNITUS: A SELF-CONTROLLED CLINICAL TRIAL

Pages

  33-38

Abstract

 BACKGROUND: Despite the high prevalence and morbidity, TINNITUS still remains an obscure symptom. We assessed the efficacy of LOW-LEVEL laser for treatment of TINNITUS.METHODS: It was a self controlled clinical trial study on 61 outpatients with subjective TINNITUS. The patients were irradiated with a 650-nm, 5-mW soft laser for twenty days and twenty minutes per day. The sensation of TINNITUS was measured on a Visual Analog Scale (VAS) before and two weeks after treatment and they were compared by means of Wilcoxon signed rank-test.RESULTS: Thirty-eight (62.3%) patients were men and twenty-three (37.7%) were women. Fourteen patients (31.8%) worked in noisy environment. The VAS mean difference before and after the treatment was statistically significant (p < 0.0001). The best treatment effect was in the youngest group and there were significant differences between this group and the middle age and older groups (p=0.018 and 0.001, respectively). The mean VAS score reduction was not statistically significant between male and female patients (p=0.23). Also, the treatment outcome according to the noise level in patient’s WORKPLACEs was not significantly different in women (p=0.693), but it was significant in men (p=0.029).CONCLUSIONS: Transmeatal LOW-LEVEL laser irradiation is effective for the treatment of TINNITUS and some variables like age and job can affect the treatment outcome.
