TMJ arthroplasty bilateral

In arthroscopic surgery, the doctor inserts tiny surgical tools and a camera into a few small cuts in your jaw. It is the type of surgery most often used for TM disorders. It is used to:

  • Remove scar tissue and cartilage that is too thick.
  • Reshape parts of the jawbone.
  • Reposition the articular disc, which cushions the ball and socket of the jaw joint.
  • Tighten the joint to limit movement.
  • Flush out the joint.
  • Insert an anti-inflammatory medicine.

In open-joint surgery, the doctor makes a large cut or incision that exposes the joint. It is used when:

  • There are bony growths in the jaw joint, which are hard to reach with arthroscopic surgery.
  • There are complications from a previous surgery.
  • The joint is fused together by bony growth.
  • The joint can't be reached with arthroscopic surgery.
Surgery for temporomandibular (TM) disorder doesn't guarantee a cure, and it can make a jaw joint problem worse. It is considered a last resort. Whenever possible, it's best to preserve the normal joint structure, rather than cutting, removing, or replacing any part of it.
