A broken jaw (or mandible fracture) is a common facial injury. Only the nose is broken more frequently. A broken jaw is the 10th most common fractured bone in the human body. Fractures (breaks in the bone) are generally the result of a direct force or trauma to the jawbone (mandible). A dislocated jawbone means that the temporomandibular joint (where the jaw connects with the skull) is moved out of place.
The mandible is the largest of all the facial bones and is the only bone of the facial bones that has the ability of movement. The mandible is able to create movement such as this through two joints which attach it to the skull known as temporomandibular joints.he lateral ridge of the orbit is also formed in part by the zygomatic bones. The zygomatic nerves and vessels are permitted passage through the zygomaticofacial foramen, which is on the surface of the bone. The lacrimal bones are thin bones that form the anterior portion of the medial walls of the individual orbits.
