Overview

Arthroscopic surgery or arthroscopy of the TM (jaw) joint is considered only after conservative, or non-surgical measures have failed to resolve limited jaw mobility and other problems related to a non-reducing displaced disc within the TM Joint.

This procedure consists of the insertion of a small, narrow tube into the jaw joint through a small incision in the skin over the joint.  Through this tube an arthroscope or small camera is inserted which is connected to a TV monitor which displays a close up image of the inside of the joint.

Surgical instruments can be inserted and various procedures can be performed under direct visualization.  These procedures may consist of:
  Debridement or removal of fragmented articular fibrocartilage which may develop with a chronically displaced disc.
  Removal of adhesions or bands of scar tissue which may develop after long-standing inflammation of the synovial tissue. These adhesions may result in a binding or freezing up of the disc and prevent it from sliding along with the condyle properly.
   Flush out or lavage the joint to remove irritating by-products of chronic joint inflammation.
   Injection of anti-inflammatory medication, much like a cortisone shot into the joint.

The procedure is performed under general anesthesia and usually take 30 minutes to an hour or more depending on the complexity of the case.  It is usually a day surgery unless there are complicating conditions.

After Surgery

There is usually minimal discomfort after this type of surgery.  Physical therapy may be started within 48 hours after the surgery in order to maintain jaw joint mobility and to prevent reformation of scar tissue. One small suture may need to be removed after about a week of the surgery.
