Mandible fracture causes vary by the time period and the region studied. In North America, blunt force trauma (a punch) is the leading cause of mandible fracture [37] whereas in India, motor vehicle collisions are now a leading cause. [38] On battle grounds, it is more likely to be high velocity injuries (bullets and shrapnel). [39]
Symptoms are specific to the type of injury; for example, fractures may involve pain, swelling, loss of function, or changes in the shape of facial structures. Facial injuries have the potential to cause disfigurement and loss of function; for example, blindness or difficulty moving the jaw can result.
The mandible in contrast has a relatively poor blood supply, which deteriorates with increasing age. The cortical plates are thick and there is a medullary cavity. The sites of the mandible most commonly affected by OM are (decreasing order of frequency) the body, the symphysis, the angle, the ramus and finally the condyle.
The symptoms of this are very similar to the symptoms of medication-related osteonecrosis of the jaw (MRONJ). Patients are in a lot of pain, the area may swell up, bone may be seen and fractures may take place. The patients may also have a dry mouth and find it difficult to keep their mouth clean.
The Le Fort III fracture (transverse fracture) occurs at the level of the skull base, resulting in complete craniofacial separation of the midface from the base of the skull. [ 2 ] [ 3 ] The fracture line extends through the zygomatic arch , the pterygoid plates , the lateral and medial orbital walls , the nasal bones , and the nasal septum .
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
The presence of buccal exostosis can be diagnosed by both clinical examination and radiological interpretation of the oral cavity. Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone. [11]
A jaw abnormality is a disorder in the formation, shape and/or size of the jaw. In general abnormalities arise within the jaw when there is a disturbance or fault in the fusion of the mandibular processes. The mandible in particular has the most differential typical growth anomalies than any other bone in the human skeleton.
