Abstract:
Objective To explore the effects and safety of low-frequency repetitive transcranial magnetic stimulation (rTMS) on treating tinnitus.Methods A total of 102 normal hearing patients with tinnitus underwent active rTMS in the left temporoparietal region.Repetitive TMS consisted of 1 000 stimulations at 1 Hz daily and 110% of the motor cortex threshold for 5 consecutive days per week (Monday to Friday) for 2 weeks.A visual analog scale (VAS) was used to assess tinnitus loudness.All participants were interviewed regarding age, gender, tinnitus duration, laterality and pitch etc.Results Low-frequency rTMS significantly decreased tinnitus in the head after the active stimulation.After rTMS treatments, 34 cases of tinnitus in the head showed an effective rate of 70.6%, in which 2 patients reported complete tinnitus disappearance (5.9%), 22 cases had significantly reduced effect.Sixty-eight patients in the control group showed an effective rate of 64.7%, in which 1 case''s tinnitus disappeared (1.5%) and 43 cases significantly reduced.According to the results of PTA,the hearing thresholds of the two groups had no significant difference between before and after the treatment.There were no headaches, dizziness, nausea, drowsiness, burns, seizures in all the patients after treatment.Conclusion Active low-frequency rTMS resulted in a significant reduction in the loudness of tinnitus in the head.
