Abstract:
Temporomandibular joint (TMJ) dislocation is a common occurrence, but diagnosis can be missed if patients do not complain. Delayed presentation complicates the management of a straightforward reduction. We present a case of a 24-year-old man who had bilateral TMJ dislocation of unknown duration after motor vehicle accident. The accident left him bedridden with speech difficulty. He was totally dependent on Ryles' and percutaneous endoscopic gastrotomy tubes for feeding. Computed tomography revealed dislocation of condyles anterior to articular eminences. The bilateral TMJ dislocations were reduced surgically via bicoronal with preauricular extension approaches. However, the surgery was challenging due to tissue changes around the joint accompanied by masticatory muscles atrophy. Postoperatively, he was placed on intermaxillary fixation for 2 weeks followed by elastics training. Three months later, the patient's mastication returned completely to function. Delayed management of bilateral TMJ dislocation is undoubtedly challenging and somewhat frustrating; nevertheless, we manage to achieve satisfactory outcome in improving the patient's quality of life.

Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...
Structural Joints: Cartilaginous Joints
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...
Joints
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
