Transcranial focused ultrasound (emerging) for Tinnitus: What Does the Evidence Show?
Brain Stimulation
Current evidence
Focused ultrasound can reach deep brain circuits no coil can — first tinnitus study starting at Oxford; no human data yet.
Evidence strength: Weak (1/5) · Tier 3 — experimental/emerging · Evidence independence: Primarily independent.
Low-intensity focused ultrasound aimed at deep tinnitus-related brain targets, non-invasively. Tinnitus Quest funded a $230k Oxford project (Robin Cleveland's lab) beginning around summer 2026.
Did tinnitus loudness or distress improve?
🧠 Did tinnitus distress improve?
None shown.
No human tinnitus data yet.
Loudness means the tinnitus percept itself became quieter (psychoacoustic matching or loudness ratings). Distress means questionnaire scores such as THI/TFI, sleep, anxiety or quality of life improved — the sound may be unchanged. A THI/TFI improvement is never evidence the tinnitus got quieter.
How strong is the evidence?
1/5 — no human data; listed because the engaged tinnitus community actively follows it.
What the studies found 0 tracked
No individual study records yet.
What are the limitations?
- No human tinnitus data of any kind
- Rationale extrapolated from tiny DBS case series
Has the result been independently replicated?
None yet.
What should patients know about safety?
Safety evidence: Not yet assessed. Unknown for this application; low-intensity protocols generally well tolerated in other indications.
Is it available?
Regulatory status: Pre-clinical / first-in-human pending. Research-stage only.
Availability: Not available · Europe: Research only (Oxford) · Cost (approx.): N/A
