Mandibular fracture, also known as fracture of the jaw, is a break through the mandibular bone. In about 60% of cases the break occurs in two places. [ 1 ] It may result in a decreased ability to fully open the mouth. [ 1 ]
Commonly injured facial bones include the nasal bone (the nose), the maxilla (the bone that forms the upper jaw), and the mandible (the lower jaw). The mandible may be fractured at its symphysis, body, angle, ramus, and condyle. [4] The zygoma (cheekbone) and the frontal bone (forehead) are other sites for fractures. [13]
An open fracture (or compound fracture) is a bone fracture where the broken bone breaks through the skin. [2] A bone fracture may be the result of high force impact or stress , or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis , osteopenia , bone cancer , or osteogenesis imperfecta ...
Unlike OM of the long bones, hematogenous OM in the bones of the jaws is rare. OM of the jaws is mainly caused by spread of adjacent odontogenic infection. The second most common cause is trauma, including traumatic fracture and usually following a compound fracture (i.e. one that communicates with the mouth or the external environment).
In jawed vertebrates, the mandible (from the Latin mandibula, 'for chewing'), lower jaw, or jawbone is a bone that makes up the lower – and typically more mobile – component of the mouth (the upper jaw being known as the maxilla). The jawbone is the skull's only movable, posable bone, sharing joints with the cranium's temporal bones.
After receiving a tip from the Ramapo team, the Yavapai County Sheriff's Department collected DNA samples from Yager's daughter, which allowed Bode Technology in Lorton, Va., to verify the bone ...
3D CT of mandible fracture. This injury involves the alveolar bone and may extend beyond the alveolus. [5] [6] There are five different types of alveolar fractures: Communicated fracture of the socket wall; Fracture of the socket wall; Dentoalveolar fracture (segmental) Fracture of the maxilla: Le Fort fracture, zygomatic fracture, orbital blowout
Fractures of the mandible are common. However, coronoid process fractures are very rare. [1] Isolated fractures of the coronoid process caused by direct trauma are rare, as it is anatomically protected by the complex zygomatic arch/ temporo-zygomatic bone and their associated muscles.
