The temporalmandibular (TMJ) joints are located near the ear, at the top of the lower jaw. These joints allow movement of the jaw.
TMJ disorders are caused by injury to this joint due to injury, arthritis or habits such as grinding the teeth at night. These disorders may produce some of the following symptoms:
- Earaches
- Headaches
- Clicking or grating noises with jaw movement
- Pain opening or closing the mouth
- Limited movement of the jaw
Not all discomfort of the jaw is the result of a TMJ disorder. In many cases, stress causes the muscles in the jaw to tense, resulting in symptoms similar to those characteristic of a TMJ disorder. Special imaging techniques may be needed to properly diagnose jaw problems and correct them accordingly.
Treatment
The necessary course of treatment is dependent on the specific diagnosis and severity of the damage to the joint. Treatment for TMJ disorders include:
- Medications for pain and muscle relaxation
- A bit plate or splint
- Stress management
- Surgical repair of the joint
- Arthroscopic surgerical repair (minimally invasive surgery)
The temporomadibular joint (TMJ) is the smallest joint located in front of the ear where the skull and lower jaw meet. It is a "ball and socket" joint with a disc made of cartilage that serves as a cushion between the parts of the joint.
