Facial injury, additionally known as maxillofacial injury, is any real injury to the face. Facial injury can involve soft muscle accidents or fractures of the facial bones such as Le Fort fractures, Zygoma (cheek bone), Mandible (jaw), Nose, Orbit (bony wall surface around the attention), and other facial bones, as well as trauma such as attention accidents. Symptoms are specific to the kind of damage; for instance, fractures may involve discomfort, inflammation, loss of function, or modifications in the form of facial structures.

Facial Bones

Facial Bones

Commonly injured facial bones range from 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. The zygoma (cheekbone) and the front bone (forehead) are other sites for fractures. Fractures may additionally take place in the bones of the palate (lips) and those that come together to develop the orbit of the eye.

As many as 50–70% of individuals who survive traffic accidents have facial injury. In most developed nations, physical violence from other individual has replaced automobile collisions as the main cause of maxillofacial injury; nevertheless in numerous developing nations traffic accidents stay the major cause. Increased usage of seat belts and airbags has been credited with a decrease in the incidence of maxillofacial injury, but fractures of the mandible (the jawbone) are perhaps not reduced by these protective steps. The threat of maxillofacial injury is reduced by a factor of two with usage of bike helmets. A decrease in facial bone fractures due to car accidents is thought to be due to seat belt and drunk driving guidelines, strictly enforced speed limitations and usage of airbags. In car accidents, motorists and passengers sitting on the front seat are at a greater risk for facial injury.

Facial fractures are distributed in a fairly regular bend by age, with a top incidence occurring between ages 20 and 40, and kids under 12 suffering only 5–10% of all facial fractures. Most facial injury in kids involves lacerations and soft tissue accidents. There are a number of reasons for the reduced occurrences of facial fractures in children: the face is smaller in connection to the rest of the head, children are less usually in some circumstances linked with facial fractures such as work-related and engine car dangers, there’s a lower percentage of cortical bone to cancellous bone in children’s faces, badly developed sinuses make the bones stronger, and fat pads offer security for the facial bones.

Head and brain accidents are commonly linked with facial injury, especially on the upper part of face; damage to the brain happens in 15–48% of individuals with maxillofacial injury. Co-existing injuries can impact therapy of facial injury; for instance they may be in the developing stage and need to be treated before facial repair. Individuals with trauma above the level of the collar bones are considered to be at large danger for injuries to cervical spine (spinal injuries in the throat) and unique precautions must be taken to stay away from moving the spine, which could aggravate a spinal damage.

Rene Le Fort utilized cadaver studies in 1900 to offer comprehensive explanations of 3 fundamental kinds of facial fracture, they’re now termed as Le Fort I, Le Fort II & Le Fort III Fractures.

LeFort Fracture

LeFort Facial Fracture Types

Le Fort made his categories depending on work with cadaver skulls, and the categorization system has been criticized as imprecise and simplistic since many mid-face fractures include a combination of Le Fort fractures. Although many facial fractures do not follow the models explained by Le Fort exactly, the system is nevertheless utilized to categorize accidents.

Causes

Damage mechanisms such as falls, sports injuries, attacks / assaults, and car crashes are typical reasons of facial injury in kids, as well as grownups. Blunt assaults, blows from fists or items, are a typical cause of facial damage. Facial injury can additionally end up from wartime accidents such as gunshots and blasts. Animal assaults and work-related accidents such as commercial accidents are other reasons. Vehicular injury is one of the leading reasons of facial accidents. Generally injury takes place when the face hits a portion of the vehicle’s interior, like the steering wheel. In addition, airbags can cause corneal abrasions and lacerations (slices) to the face when they have been used.

Clinical Presentation:

Fractures of facial bones, like other fractures, may be associated with discomfort, bruising, and inflammation of the surrounding cells (such signs can happen in the absence of fractures as well). Fractures of the nose, base of the skull, or maxilla may be connected with profuse nosebleeds. Nasal fractures may be linked with deformity of the nose, as well as inflammation and bruising. Deformity in the face, for instance a sunken cheekbone or teeth which do not align correctly, suggests that a fracture is existing. Asymmetry can be interpreted as facial fractures or harm to nerves. Individuals with mandibular fractures frequently have discomfort and trouble while opening their mouths and may have numbness in the lip and chin. With Le Fort fractures, the mid-face may move relative to the rest of the face or skull.

Treatment

The 3 objectives of treatment in dealing with facial fractures are (1) to restore functional occlusion; (2) to support the major facial skeletal supports, thus bringing the pre-morbid 3-dimensional facial contour (height, width, and projection) back to normal; and (3) to offer skeletal support for the appropriate function and look of the overlying facial soft tissue structures.

The present approach to facial fracture repair calls for the repositioning of the broken portions into anatomic place, with a focus on the lattice supports in connection to each other and to the cranial base. Contemporary therapy additionally mandates the rigid stabilization of the straight and horizontal facial aids to withstand the forces of mastication – Open Reduction & Internal Fixation (ORIF). Such treatment plans are made feasible by the diagnostic ability of computed tomographic (CT) scanning technology, a major advance over plain x-rays, for fracture recognition and fragment visualization.

  • Very first priority is to perform a primary review and attend to ABCs (Airway, Breathing & Circulation – the 3 indications of security in a client), as maxillofacial fractures are triggered by significant injury. At first, concentrate on evaluation of airway patency, respiration, blood circulation, and gross neurologic function, as well as control of the cervical spine.
  • Treatment aims to restore the face’s natural bony framework and to keep as little obvious trace of the damage as feasible. Fractures may be fixed with metal plates and screws. They may additionally be wired into place. Bone grafting is another choice to restore the bone’s architecture, to fill away lacking parts, and to supply structural support. Medical literature recommends that very early repair of facial accidents, within hours or days, outcomes in much better results for function and look. Medical professionals who commonly treat certain aspects of facial injury are facial plastic surgeons. These surgeons are trained in the comprehensive handling of injury to the lower, middle and upper face and have to take written and oral board exams addressing the handling of facial accidents.
