When non-surgical methods have failed to give relief in TMJ disorders, then surgical treatment can be opted for. The various modalities of treatment available are-
1. Injection of steroids into the joint space– This reduces the inflammation and pain associated with problems within the bone across the joint.
2. Arthrocentesis– This procedure is performed under local anesthesia. It is done when-
- steroid injection does not give any relief in pain or
- reduce the inflammation and
- the condition has progressed to even having difficulty opening the mouth.
Arthrocentesis is also done when the jaw suddenly locks in the closed position. It is done with the help of a needle inserted into the TM joint and then irrigation is done with saline fluid to wash off the debris and the products of inflammation out of the joint.
3. Arthroscopy- This procedure is performed under general anesthesia. A small incision is made in front of the year and Arthroscopy with the light is inserted in TMJ and the whole joint is inspected and washed under vision. Any piece of inflamed tissue or debris is removed.
Because arthroscopic surgery is performed through tiny incisions, there is less scarring, a shorter recovery time, less discomfort, and fewer complications compared with open-joint surgery.
4. Open-joint surgery– It is done under general anesthesia and a longer incision is placed within the curvature of your ear which is very well hidden.
What are the indications for open TMJ surgery?
Open joint surgery is indicated in
- If you hear a clicking sound from the joint + an MRI reports internal derangement of the articular disc. In this, we need to repair or reposition the articular disc of the joint.
- Any tumors in and around the TM joint
- TM joint dislocations
- Severe arthritis of the bony structures involving the joint which leads to TM Joint replacement.
