Efficacy of non-invasive neuromodulation for chronic tinnitus: a systematic review and meta-analysis of randomized controlled trials

Chronic tinnitus affects approximately 14% of adults worldwide, with nearly 2% experiencing severe, persistent symptoms that impair daily functioning. Non-invasive neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), and acoustic or nerve stimulation, have emerged as potential therapies, yet their clinical effectiveness remains...

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

Findings may support adding non-invasive neuromodulation as an adjunct for chronic tinnitus, but clinicians should await the full paper's effect-size and safety data before changing protocols.

✦ Why It Matters ✦

A meta-analysis of RCTs on non-invasive neuromodulation provides the highest level of evidence to date on whether these increasingly popular techniques meaningfully reduce tinnitus burden.

✦ Key Points ✦

01Chronic tinnitus affects approximately 14% of adults globally, representing a large unmet clinical need.
02Review synthesises randomised controlled trials (RCTs) of non-surgical brain stimulation for tinnitus.
03Non-invasive neuromodulation approaches include techniques such as transcranial magnetic or electrical stimulation.
04Systematic review and meta-analysis design offers the highest level of evidence (Oxford CEBM 1a).
05Published in European Archives of Otorhinolaryngology.
