Temporomandibular (TM) Disorders-Surgery

Temporomandibular (TM) Disorders - Surgery

Surgery is rarely used to treat temporomandibular (TM) disorders. Surgical treatment does not guarantee a cure and can further damage the temporomandibular joint. Because most TM disorders can be treated nonsurgically, most doctors believe that surgery should be the last option tried and should be avoided if possible.

Surgery may be a treatment option for you if both of the following apply:

Other treatments have failed, and chronic jaw pain and dysfunction have become disabling.
There are specific, severe structural problems in the jaw joint. These include scar tissue in the joint area, problems with bone alignment, broken or degenerated bones, and occasionally disc displacement or perforation.

The goals of surgery for temporomandibular (TM) disorders are to:

Relieve pain in the jaw joint.
Correct any structural problems.
Restore normal jaw function.

Surgery Choices

Arthrocentesis. This is not a true surgery, since there is no incision. But it is an invasive procedure performed by an oral and maxillofacial surgeon. Arthrocentesis to wash out the joint area (lavage) seems to work for people who have severe closed lock of the temporomandibular joint.⁵

Surgery may include:

Arthroscopic procedures, including washing out the joint area (lavage), cutting or removing scar tissue that is blocking joint movement (lysis), cutting tissue that has shortened and is impeding joint function, or shaving part of the disc.
Open joint arthroplasty, used for disabling joint problems that aren't easily reached or viewed arthroscopically.

Another type of surgery, called total joint replacement, is rarely done. It has sometimes resulted in permanent jaw damage. Total joint replacement replaces the jaw joint with artificial parts. In some cases the artificial parts have not worked correctly or have broken. The available technology for this surgery is still considered to be experimental and risky.

What To Think About

Further pain complications or joint dysfunction can result from temporomandibular joint surgery.

Surgery is not necessary in most cases of disc displacement.⁵ Splint therapy (a dental treatment), jaw rest, and physical therapy, including moist heat and jaw exercises followed by an ice pack, can work very well for treating this condition. If this and other nonsurgical treatment to relax the muscles are not successful, arthrocentesis may effectively treat your condition.

If you are thinking about surgery, get a second opinion on your condition and treatment.

Only 18.5% of Americans never floss. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Floss removes food trapped between the teeth and removes the film of bacteria that forms there before it turns to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Try flossing just one tooth to get started.

You are one of 31% of Americans who don't floss daily. You are missing out on a simple way to make a big difference in the health of your mouth. Regardless of how well you brush, plaque still forms between your teeth and along your gums. Toothbrush bristles alone cannot clean effectively between these tight spaces. Flossing removes up to 80% of the film that hardens to plaque, which can cause inflamed gums (gingivitis), cavities, and tooth loss. Aim for 3 more days!
