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.
Exposed and necrotic bone or a fistula that probes to bone in patients with pain, infection, and one or more of the following: exposed and necrotic bone extending beyond the region of alveolar bone (i.e., inferior border and ramus in the mandible, maxillary sinus and zygoma in the maxilla) resulting in pathologic fracture, extra-oral fistula ...
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 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.
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.
Fracture of the maxilla: Le Fort fracture, zygomatic fracture, orbital blowout; Fracture of the mandible; Trauma injuries involving the alveolus can be complicated as it does not happen in isolation, very often presents along with other types of tooth tissue injuries. Signs of dentoalveolar fracture: Change to occlusion
A fracture through the sella can lead to profuse blood aspiration. A common mechanism for transverse fractures is a sharp blow to the chin, such as a fall onto a hard surface. The impact energy transfers to the skull base via the mandibular rami and temporomandibular joints. The chin injury may appear minor, often just a small abrasion or ...
