A TMJ (Temporomandibular Joint) injection is a procedure to reduce friction and alleviate pain within the jaw joint. Specifically, a TMJ injection performed with a hyaluronic acid solution is done to temporarily reduce friction between the joint surfaces.
Understanding TMJ Injections
TMJ injections involve injecting medication directly into the temporomandibular joint to manage pain and improve joint function. Here’s a more detailed look:
Purpose
The primary goals of TMJ injections are to:
- Reduce pain.
- Decrease inflammation.
- Improve joint mobility.
Hyaluronic Acid Injections
Hyaluronic acid (HA) is a substance naturally found in the joint. When used in TMJ injections, it acts as a lubricant.
Benefits of Hyaluronic Acid
- Reduces Friction: It helps reduce friction between the joint surfaces.
- Pain Relief: Provides relief from painful clicking.
- Addresses Locking: Useful for episodic locking of the TMJ.
- Manages OA Flare-ups: Effective during acute osteoarthritis (OA) flare-ups.
Common Scenarios for TMJ Injections
TMJ injections are typically considered when patients experience:
- Painful clicking in the jaw joint.
- Acute osteoarthritis flare-ups.
- Episodic locking of the TMJ.
