If short term application of rTMS is proven to be significantly effective, more effective treatment of tinnitus can be expected. This study was conducted to measure the effect of one session of sham rTMS & one real trial of rTMS in chronic unilateral tinnitus patients. Subjects and MethodZZrTMS stimulation of 1 Hz and 100% magnitude was given 1200 times per day to 33 patients with chronic unilateral tinnitus on their left side, between T3 and C3/T5, following the convention of the 10-20 International EEG system. Visual Analogue Scale (VAS) and Tinnitus Handicap Inventory (THI) scores were measured four times-immediately before rTMS, immediately after sham rTMS, immediately after real rTMS and two weeks after real rTMS. ResultsZZVAS and THI scores were found to show a tendency of declining. Immediately after real rTMS application, a significant decrease in VAS and THI scores was observed compared to those measured immediately before rTMS (p 0.05) attributable to the direction of tinnitus were observed. ConclusionZZA single session rTMS is thought to be a possible adjunctive treatment for temporary relief of tinnitus. Korean J Otorhinolaryngol-Head Neck Surg 2012;55:216-21
