Low level laser therapy (LLT) for chronic tinnitus

ABSTRACT Background The aim of this study was to assess the efficacy of chronic subjectictive tinnitus treatment with Low Level Laser. Materials and methods 42 patients with chronic subjective tinnitus were included in the study. The study included patients suffering from monolateral or bilateral tinnitus more than 3 months prior to Low Level Laser treatment with no concomitant treatments for tinnitus. The subjects were treated with Low Lewel Laser (wave-lenght 650 nm, output 50 mW) for 10 sessions, 2-3 sessions per week, twenty minutes per session. The tinnitus was measured before and after the treatment with Tinnitus Handicap Inventory (THI) and Visual Analog Scale (VAS) and the results were statistically analysed by Wilcoxon signed-rank test. Results All 42 patients completed Low Level Laser Therapy which was well tolerated. The adverse or side effect were not observed. Twenty- five (59.5%) patients were men and seventeen (40.5%) were women. Visual Analog Scale (VAS) score improvement of tinnitus intensity was: 1 degree (14.3%), 2 degrees (19%), 3 degrees (14.3%), 4 degrees (4.8%), 5 degrees (9.6%). No improvement showed 38.1% of treated patients. Visual Analog Scale (VAS) score mean before the treatment was 6.9 (± 1.8) and after the treatment was 5.4 (± 2.4). The VAS score difference before and after the treatment was statistically significant (p < 0.001). No statistical difference was found before and after the tratment in the Tinnitus Handicap Inventory (THI) score (p = 0.752).
