Vagus Nerve Stimulation for Tinnitus

Does vagus nerve stimulation help with tinnitus? 24 human studies have investigated VNS for tinnitus, including 3 systematic reviews, 2 RCTs, and 12 controlled trials, published between 2012 and 2026, with 8 published since 2022. Studies use transcutaneous auricular (taVNS), implanted (iVNS), and transcutaneous cervical (tcVNS) stimulation. Findings vary by study design and population; the studies below are ranked by evidence strength so you can weigh the research directly.
