Could a blood concentrate make cochlear implants work better?
NCT ID NCT05215197
First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time
Summary
This trial investigates whether applying platelet-rich fibrin inside the ear during cochlear implant surgery can reduce scarring and improve implant performance. Scarring often limits how well the implant works and increases its power use. The study includes people with sensorineural hearing loss who are receiving a specific type of cochlear implant. Researchers will measure electrode impedance and thresholds over six months to see if the treatment helps.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- platelet-rich fibrin applied inside the cochlea during cochlear implant surgery
- What this could lead to
- If it works, this could improve hearing outcomes and reduce power needs for cochlear implant users.
- What could go wrong
- This is a very small early study with only 10 participants, so results may not apply broadly. The procedure also carries surgical risks.
