Efficacy of percutaneous vagal stimulation in the treatment of chronic tinnitus

Objective:The aim of this study is to investigate the efficacy of transcutaneous vagus nerve stimulation(tVNS) in the treatment of chronic tinnitus. Methods:taVNS was used to treat chronic decompensated tinnitus, 10 days as a course of treatment. Record and analyze the improvement of the patient’s subjective symptoms during treatment. The THI, PSQI and DASS-21 scores were performed at 10 days, 3 months and 6 months after treatment. The improvement of tinnitus in taVNS group and control group at the above recorded time points was compared, and the THI score of taVNS group was compared before and after treatment. Results:① During the taVNS treatment, 93.65% of the patients achieved improvement in subjective symptoms, and 28.6% of the patients voluntarily accepted the second course of taVNS treatment; ② The sleep improvement was optimal when the treatment was 10 days, and some patients had poor sleep status after 3 or 6 months; ③ The anxiety of taVNS group was improved during and after treatment, and the best effect time was 3 months and 6 months after treatment; ④ There was no significant difference in THI score between the two groups, but there was significant improvement in taVNS group at 3 months and 6 months after treatment. Conclusion:tVNS treatment can significantly improve the sleep disorder, anxiety disorder and tinnitus disturbance of tinnitus patients, and the curative effect is good after 3 months and 6 months of prevention.
