Temporomandibular joint (TMJ) is formed by the articulation of the mandible and the temporal bone of the cranium. It is located anteriorly to the tragus of the ear, on the lateral aspect of the face.
In this article, we shall look at the anatomy of the temporomandibular joint , its articulating surfaces, ligaments and clinical correlations.

Ligaments of TMJ

There are three extra capsular ligaments. They act to stabilize the temporomandibular joint.
1)Lateral ligament – runs from the beginning of the articular tubule to the mandibular neck. It is a thickening of the joint capsule, and acts to prevent posterior dislocation of the joint
2)Sphenomandibular ligament – originates from the sphenoid spine, and attaches to the mandible.
3)Stylomandibular ligament : thickening of the fascia of the parotid gland. Along with the facial muscles, it supports the weight of the jaw.

TMJ dysfunction (TMD) :
causes pain and tenderness in your jaw joints and surrounding muscles and ligaments. Causes include teeth grinding, jaw injuries, arthritis and everyday wear and tear. TMJ treatment varies from person to person and may include medication, physical therapy, custom mouth guards and jaw surgery.
