The Effects of Stellate Ganglion Stimulation and Stellate Ganglion Block for Tinnitus / 日本温泉気候物理医学会雑誌

ABSTRACT

The relationship between the subjective changes in tinnitus and recovery of the hearing loss was studied by applying SG (Stellate Ganglion) stimulation or SGB for the same patient. The results obtained are as follows.<br>1. Subjective tinnitus either decreased or increased in many cases after SG stimulation and SGB.<br>2. Application of SG stimulation or SGB for the same patient resulted in similar changes in many cases.<br>3. Tinnitus associated with sudden deafness increased in many cases after SG stimulation or SGB.<br>4. Tinnitus showed no change after SG stimulation or SGB in cases of fresh sudden deafness in which the hearing was not restored.<br>5. SG stimulation and SGB are supposed to be contrary to each other in the effect on the sympathetic nerve, but the two showed similar effects so far as tinnitus is concerned.<br>By effects SG stimulation and SGB therefore, one can estimate the individual difference, pathological phenomenon and the ability to response of the patients.
