Transcutaneous Auricular Vagus Nerve Stimulation for Meniere Disease

TaVNS device (Elmmedicare, EC100, Shenzhen, China) was used to apply stimulation for patients. Stimulation parameters comprised an electrical current of 1 mA at a frequency of 20 Hz, with a waveform width of 1 ms \[18,28\]. Repurposed off-the-shelf devices were utilized for this purpose, with the stimulator generating single square-wave pulses lasting 1 ms each. Enhancing conductivity was achieved by wiping the ear with tap water. In the taVNS group received 12 weeks of treatment (30 min each time, once daily, 5 times per week).

Betahistine Mesylate tablet (Merislon, Eisai Co., Ltd., China) with the treatment of 6 mg 3 times a day.
