Can a placental patch make neck surgery scars heal better?
NCT ID NCT07173621
First seen Jun 26, 2026 · Last updated Aug 04, 2026 · Updated 2 times
Summary
This study tests whether placing a placental-based allograft called Amnioeffect on the surgical wound improves scar appearance, pain, and swallowing after thyroid or parathyroid surgery. About 334 adults will be enrolled, with half receiving the graft and half getting standard care. The goal is to see if this simple addition leads to better healing and quality of life.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Amnioeffect (a placental-based allograft made from human amnion/chorion membrane)
- What this could lead to
- If it works, this could offer a simple way to improve scar healing and reduce discomfort after neck surgery.
- What could go wrong
- This is an early-stage study with no phase, so results are uncertain. The benefit over standard care may be small or none, and the allograft carries a low risk of allergic reaction.
