The Study on Effect and Neural Network Mechanism of Transcranial Direct Current Stimulation for Sudden Deafness With Tinnitus

Summary

This clinical study is prospective, single-center, randomized, controlled, double-blind clinical trail, which entitled transcranial electrical stimulation for the treatment of acute tinnitus approved by Sun Yat-sen University, and intends to recruit 86 patients with sudden deafness and tinnitus. For acute subjective tinnitus, a common otological disease, the study gave the experimental group patients received tDCS with electrodes positioned over the left temporal cortex for 5 days. To assess the efficacy of conventional medical therapy and tDCS by comparing changes in anterior and posterior tinnitus-related subjective scale scores, such as THI, VAS, BAI, BDI, PSQI, and hearing recovery, in patients who received tDCS, to determine whether tDCS is effective in improving acute tinnitus, and whether it is superior to conventional tinnitus treatment. In addition, the study will continue to follow patients for 1 month,3 months, and 6 months after the end of treatment to observe the long-term sustained efficacy of tDCS. This clinical trail will also evaluate tDCS from the perspective of compliance and safety, and explore the factors affecting the efficacy of this therapy.

Interventions

DEVICE

Receive traditional medical therapy and transcranial direct current stimulation

Equipment used: Bricon tDCS stimulator, high-precision electrode stimulation method Stimulant dose: 1.5mA Stimulation time: 20 minutes/time, continuous treatment for 5 days Stimulation course: 5 days/course Stimulation target: left auditory cortex area, i.e., under system 10-20, left T3 position.

DEVICE

Receive traditional medical therapy and sham stimulation

By controlling the tDCS stimulator to mimic only the first 30 seconds of tDCS stimulation, after 30 seconds of pathway resistance control, so that the stimulation intensity is below the threshold, without giving real stimulation, in this process, the position of the stimulation target is not changed, and the rest of the operation is the same.
