Abstract :
Background and Aim: Tinnitus is a distressing symptom for which few treatments exist. Lowfrequency repetitive transcranial magnetic stimulation (rTMS) of the temporal cortex has been proposed as a treatment for chronic tinnitus. This study determined relationship between psychoacoustic parameters such as loudness and frequency of tinnitus and outcome with rTMS treatment.
Methods: Twenty six patients (22 male, 4 female) with chronic tinnitus received low frequency (1 Hz) rTMS at intensity 110% motor threshold and 1200 stimuli on three subsequent days to the left auditory cortex. The treatment outcome was assessed with loudness balance test and Tinnitus Handicap Inventory (THI).
Results: There was a significant difference between loudness of tinnitus and THI scores before and after rTMS. There was no correlation between psychoacoustic parameters loudness and frequency of tinnitus and rTMS treatment outcome.
Conclusion: Our data suggest that repetitive transcranial magnetic stimulation, regardless of loudness and frequency of tinnitus, can be used as a therapeutical tool for the treatment of tinni-tus.
