Craniofacial injuries (ie, fractures, malleable tissue damage) usually are die issue of motor vehicle collisions (MVCs) physical assaults, gunshot injurys contact-sports mishaps, and occupational and home-related accidents. These injuries are caused by way of deceleration, blunt, or penetrating trauma. Depending forward the mechanism of injury, the face can be fractured at any site. Craniofacial fractures from crushing forces are sustained in MVC when individuals' faces strike dashboards, windshields, or the loam Craniofacial fractures from tapping forces be found when energy that has diminishing impetus is applied over a small surface area (eg bangs from kicks, baseball bats).(1) Penetrating trauma injuries frequently are caused by gunshot hurts from low-or high-velocity missiles or from metal projectiles (eg caused by dint of lawn mowers, farm equipment) that penetrate craniofacial pliable tissues and bones.

Craniofacial fractures can present itself as incomplete, multiple, or comminuted fractures of different signs Incomplete fractures involve two bone parts and interrupt only the cortical or exterior layers of bone. Multiple fractures posses a minimum of three bone portions and comminuted fractures have many small hesitating bone fragments.(2) Craniofacial fractures require reconstructive materials of differing strengths; therefore, the ne for various intermaxillary fixation devices is imperative. any reconstructive surgical procedures require several separate maneuvers and may last three to 16 hours or longer(3)

EVOLUTION OF CRANIOFACIAL SURGERY

The disentanglement of reconstructive surgical procedures for craniofacial injuries began during World Wars I and II. Surgeons' experiences in these brace wars resulted in the evolution of basic surgical techniques for the replacement of missing craniofacial bone plastic tissues, and skin. These early surgical techniques demonstrated that adequate corrections could be achieved by the agency of repositioning displaced parts of patients' craniofacial skeletal frameworks. Increasingly manifold craniofacial surgical procedures have been performed routinely since World War II.(4) During the late 1940 and early 1950 surgeon made their first attempts to ameliorate cull congenital craniofacial deformities.

A French surgeon Dr Paul Tessier, demonstrated that large portions of craniofacial bones could be denud completely of their posterity supplies, be repositioned, and survive. He further demonstrated that the views could be translocated horizontally or vertically above considerable distances without impairing patients' vision. Dr Tessier's surgical approaches to craniofacial surgical injuries l to surgical treatments for previously inaccessible anatomical areas of the face(5) and conclusioned in the development of today's orbital-craniofacial surgical subspecialty service. novel craniofacial surgical techniques have enabled surgeon to correct bitter deformities of the skull and face and associated malleable tissue injuries.(6) A multidisciplinary team approach frequently is required for the treatment of craniofacial injuries, with specialists in plastic and reconstructive surgery neurosurgery ophthalmology, oral maxillofacial surgery and otorhinolaryngology participating in patient care activities.(7)

CRANIOFACIAL BONE ANATOMY

The season craniofacial refers to the cranium (ie, the bony piles of the forehead; top, back, and upper sides of the skull) and the face (ie, cheeks, nose, lips, chin). The skeletal pile of the face (Figure 1) includes the frontal bone of the forehead and 14 craniofacial bone (ie, sum of two units each: nasal, maxillary, lacrimal, zygomatic, palatine, nasal conchal bones; united each: vomer, mandible). As in the cranium, the craniofacial bone are fused into immovable joints, leave out for the mandible (ie, lower jaw).(8)

The frontal bone forms the upper part of the estimate orbits by articulating with the sphenoid, ethmoid, and paired nasal, lacrimal, maxillary, and zygomatic bone The posterior organ of vision orbits are formed by the sphenoid and palatine bone The medial walls of the observation orbits are formed by the ethmoid, lacrimal, nasal, and maxillary bone The lateral aspects of the vigilance orbits are formed by the zygomatic bone The ethmoid bone form the arch and posterior lateral walls of as well-as; not only-but also; not only-but; not alone-but nasal cavities, and the nasal bone form the bridge of the nose between the sum of two units eye orbits.(9)

Craniofacial bone are relatively thin and unsupported. They house organs, bones, and tissues that lie within and behind their mode of buildings (eg, eyes, lacrimal apparatus, pharynx, cervical spine, brain). They also provide an apparatus for mastication (ie, chewing) and a vestibule to the respiratory and vocal organs.(10) The maxillae (ie, upper jaw bones) retain the palate and join in the midline between the nose and oral cavity. The alveolar processe (ie, tooth-bearing bodies) of the maxillae gripe [i]or[/i] grip the upper teeth. The mandible articulates with the temporal bone at the temporomandibular joints (TMJs) which are anterior to the ears, and befittings midline in the mental region to form the chin. The alveolar processe of the mandible restrain the lower teeth.(11)
