Tinnitus, a subjective auditory perception of sounds or noise not triggered by external auditory stimuli, carries considerable morbidity. To date, pharmacological, physical or behavioral therapy is the mainstay of management.


We compared repetitive transcranial magnetic stimulation (rTMS) of 1000 or 2000 stimulations/day at 1 Hz and 110% of the motor threshold for 5 consecutive days over the left auditory cortex. Ratings based on the Tinnitus Handicap Inventory (THI) rating scale were completed weekly for 4 weeks. None of the patients had significant hearing impairment.


All 28 patients (age range 21-72; 18 men) tolerated rTMS well and no adverse effects were observed. Analysis of variance (ANOVA) showed significant decrease in THI scores over the entire time period (F (1,26)=11.33, p=0.002).
At every weekly time point of evaluation, ANOVA with repeated measures demonstrated significantly lower THI score compared to baseline.

RTMS treatment had resulted in tinnitus reduction in the range of 15-25% over the 4 week period. Separately, ANOVA also demonstrated significantly reducing THI for both the 1000 pulse (F (1,14)=4.8, p=0.04) and 2000 pulse (F (1,14)=6.56, p=0.02) rTMS treatment arms. Comparison of THI ratings between the 2 treatment arms did not result in significant difference (F (1,26)=1.48, p=0.24).


The present study has revalidated the efficacy and safety of rTMS for improving tinnitus up to 4 weeks post-treatment in Asians. However, there was no significant difference with THI evaluation between the 1000 pulse and 2000 pulse treatment arms.
