An MRI of the temporomandibular joint (TMJ) is a diagnostic imaging technique used to assess the joint's structure and function. It provides detailed images of the soft tissues, including muscles, ligaments, and the articular disc, which are not well visualized with X-rays.
Indications for MRI of TMJ:
- Persistent jaw pain or dysfunction
- Clicking or popping sounds during jaw movement
- Limited jaw mobility
- Evaluation of TMJ disorders, such as:
- Disc displacement
- Arthritis
- Osteoarthritis
- Inflammatory conditions
What to Expect:
- Preparation: Generally, no special preparation is needed. You may be asked to remove metal objects and jewelry.
- Procedure: You'll lie down inside a large, tube-shaped magnet. The MRI machine makes loud noises, so you may be given earplugs. The scan typically takes 30 to 60 minutes.
- After the Scan: You can resume normal activities immediately.
Interpretation:
A radiologist will analyze the images and report on any abnormalities, which can help guide treatment options. Common findings might include:
- Disc displacement
- Joint effusion (excess fluid)
- Bone changes or degeneration
If you have specific concerns or symptoms related to TMJ, consulting a healthcare provider for a personalized evaluation and treatment plan is advisable.
