New needle method may better protect voice nerves during neck surgery
NCT ID NCT07638579
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two methods of monitoring the nerve that controls the vocal cords during thyroid and parathyroid surgery. The standard method uses a breathing tube with electrodes, while the new method uses tiny needles placed directly into the voice box cartilage. Researchers will test both methods on 300 adults to see which one more accurately detects nerve injury, helping surgeons protect the voice.
