Ultrasound vs. arthroscopy: which injection works better for TMJ pain?
NCT ID NCT07535073
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests two methods of injecting platelet-rich fibrin (PRF) into the jaw joint for people with a displaced disc that causes pain and limited mouth opening. One method uses ultrasound to guide the needle, the other uses a tiny camera (arthroscope). The goal is to see which approach reduces pain and improves jaw function better. The trial will enroll 18 adults who have not improved with standard treatments like splints or physical therapy.
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 (PRF) injection
- What this could lead to
- If successful, this could show that a simpler, ultrasound-guided injection works as well as arthroscopic surgery for TMJ pain, offering a less invasive option.
- What could go wrong
- This is a very small early trial (18 people) comparing two procedures, so results may not apply widely. PRF injections may not provide lasting relief, and both procedures carry risks like infection or pain.
