FRACTURAS LEFORT PDF

Le Fort fractures are fractures of the midface, which collectively involve separation of all or a portion of the midface from the skull base. In order to be separated from the skull base, the pterygoid plates of the sphenoid bone need to be involved as these connect the midface to the sphenoid bone dorsally. The Le Fort classification system attempts to distinguish according to the plane of injury. Any combination is possible.

The Le Fort classification system attempts to distinguish according to the plane of injury. Any combination is possible. It should be noted that Le Fort fractures are often associated with other facial fractures, neuromuscular injury and dental avulsions. Le Fort conducted experiments on 35 cadavers inflicting varying facial trauma by dropping cannon balls and striking them with a bat. He would then boil the heads to remove soft tissue and record the results 4,5.

Le Fort Fractures: A Collective Review

A Le Fort fracture of the skull is a classic transfacial fracture of the midface, involving the maxillary bone and surrounding structures in either a horizontal, pyramidal or transverse direction. The hallmark of Lefort fractures is traumatic pterygomaxillary separation , which signifies fractures between the pterygoid plates , horseshoe shaped bony protuberances which extend from the inferior margin of the maxilla , and the maxillary sinuses. Continuity of this structure is a keystone for stability of the midface, involvement of which impacts surgical management of trauma victims, as it requires fixation to a horizontal bar of the frontal bone. The pterygoid plates lie posterior to the upper dental row, or alveolar ridge, when viewing the face from an anterior view.
