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 .
A skull fracture is a break in one or more of the eight bones that form the cranial portion of the skull, usually occurring as a result of blunt force trauma.If the force of the impact is excessive, the bone may fracture at or near the site of the impact and cause damage to the underlying structures within the skull such as the membranes, blood vessels, and brain.
Longitudinal fracture: This type divides the base of the skull into two halves (right and left). It may result from blunt impact on the face, forehead, back of the head, or from front-to-back crushing forces. [6] Transverse fracture: This type divides the base of the skull into a front and rear half.
The most common method to reconstruct the midface is by using the fracture/ incision lines described by René Le Fort. When the cleft involves the maxilla, it is likely that the impaired growth will result in a smaller maxillary bone in all 3 dimensions (height, projection, width).

Salter–Harris Fracture Types. There are nine types of Salter–Harris fractures; types I to V as described by Robert B. Salter and William H. Harris in 1963, [3] and the rarer types VI to IX which have been added subsequently: [5] Type I – transverse fracture through the growth plate (also referred to as the "physis"): [6] 6% incidence
In human anatomy, the asterion is a visible (craniometric) point on the exposed skull.It is just posterior to the ear.It is the point where three cranial sutures meet: . the lambdoid suture.
