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.
When zygoma fractures occur, the most typical symptoms are paresthesias in the upper lip, nose, cheek, and lower eyelid, diplopia, and pain.Particular physical characteristics that support zygomatic fracture include globe injury, impaired ocular motility, globe malposition, orbital emphysema, trismus, palpable stepoffs at the inferior or upper lateral edge of the orbit, reduced feeling ...
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.
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
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.

The most important feature is pain, followed by restricted mandibular movement, [2] and noises from the temporomandibular joints (TMJ) during jaw movement. Although TMD is not life-threatening, it can be detrimental to quality of life; [3] this is because the symptoms can become chronic and difficult to manage.
