Conclusion Le Fort fractures are specific patterns of facial bone fractures that develop secondary to blunt facial trauma. Rene Le Fort's seminal classification system for maxillary fractures has been the standard for over years. As the classification increases, the anatomic level of the maxillary fracture ascends from inferior to superior with respect to the maxilla: Like the nose, the mandible also has a prominent position on the face, making it a favorite target for either of these mechanisms. All Le Fort fracture types involve the pterygoid processes of the sphenoid bones and therefore, disrupt the intrinsic buttress system to the midface-however further differentiation of Le Fort types I, II, and III depends on involvement of the maxillary, nasal, and zygomatic bones [ 3 - 5 ]. If a computed tomography CT reveals bilateral pterygoid fractures, a Le Fort fracture should be suspected.

Impacted type of fractures may be almost immobile and it is only by grasping the maxillary teeth and applying a little firm pressure that a characteristic grate can be felt which is diagnostic of the fracture.

The LeFort II occurs along yet another weak zone in the face, and is sometimes called a pyramidal fracture because of its shape.

Higher grade Le Fort fractures were also associated with increased rates of concomitant head and neck injuries that most commonly involved skull fracture J Trauma Acute Care Surg. Interpersonal violence and facial fractures. When anteriorly displaced and impacted or when partially healed, maxillary fractures placed in IMF, without a complete mobilization and repositioning of the maxilla, allow the mandibular condyle to easily move anteriorly into the glenoid fossa to permit occlusal contact of the mandible with an impacted, malpositioned maxilla.
