For arthroscopic jaw surgery, the surgeon inserts a pencil-thin,
lighted tube (arthroscope) into the jaw joint through a small incision in the
skin. The arthroscope is connected to a small camera outside the body that
transmits a close-up image of the joint to a TV monitor.
The surgeon can insert surgical instruments through the arthroscope
to do surgery on the joint, preventing the need for more surgical
incisions. This technique is used to diagnose and treat
temporomandibular disorders (TMD).
During arthroscopic surgery, the surgeon may:
Procedures are done under
general anesthesia and usually take 30 minutes or
longer depending upon the type of procedure.
After surgery, you may start physical therapy within 48 hours in

Arthroscopy can be used to treat TMDs involving:
This procedure may also be used to diagnose a TMD (diagnostic arthroscopy).
Arthroscopy is not done when there is:
Arthroscopy is a minimally invasive surgery that can effectively treat TMDs. An arthroscopic surgery can effectively treat a TMD with fewer and less severe complications compared with an open-joint surgery.1
Complications of arthroscopic temporomandibular surgery are
uncommon but include:
Any surgical changes to the bone and soft tissue are irreversible
and can create new problems in the joint's delicate balance. Scar tissue
results from surgery that involves muscles, tendons, and ligaments and is
likely to restrict jaw movement to some extent.
When possible, a nonsurgical approach is preferred over surgery,
because the treatment is cheaper, safer, noninvasive, and involves less risk of
Current practice trends are to avoid altering disc position or
structure. After disc replacement, an adverse reaction to an artificial disc
If your doctor recommends surgery, experts agree that
