Gentle zap during thyroid surgery may save Patients' voices
NCT ID NCT07706699
First seen Jul 16, 2026 · Last updated Jul 17, 2026 · Updated 1 time
Summary
This study tests whether using a low electrical current (3 or 5 milliamps) during thyroid surgery helps surgeons locate and avoid damaging the nerve that controls the voice box. About 150 adults having their first thyroid surgery will be randomly assigned to one of two current levels. The main goal is to see if this technique reduces the number of patients with permanent voice loss six months after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- low-current electrical stimulation (3 mA or 5 mA) used during surgery to help identify the nerve that controls the voice box
- What this could lead to
- If effective, this simple technique could become a standard step in thyroid surgery to lower the risk of permanent voice damage.
- What could go wrong
- This is a single-center study with 150 participants, so results may not apply broadly. The stimulation itself is low-risk, but the main risk is that it may not reduce nerve injury compared to standard methods.
