It is the small joint located directly in front of the ear. This joint allows for movement of the lower jaw during opening and closing. TMJ disorders, dysfunction, and TMD are terms that describe a malfunction or problem related to this joint and its associated components, mainly its muscles and ligaments. Ankylosis is fusion of the joint due to injuries or infection usually occurring in childhood leading to inability to open the mouth with distorted face growth(crooked face). Treatment is surgery in a multistage manner to open the mouth and cosmetically reconstruct the jaws and face.
