What is LeFort fracture?
Le Fort I level fractures are essentially a separation of the hard palate from the upper maxilla due to a transverse fracture running through the maxilla and pterygoid plates at a level just above the floor of the nose.
How many types of LeFort fractures are there?
These fractures are classified into three distinct groups based on the direction of the fracture: horizontal, pyramidal or transverse.
What is LeFort classification?
The classification of Le Fort fractures is based on the plane of injury: type I is a horizontal injury, type II is a pyramidal injury, and type III is a very extensive transverse injury that often results in a craniofacial dislocation.
What is a LeFort III fracture?
Le Fort III fracture (transverse), otherwise known as craniofacial dissociation, may follow impact to the nasal bridge or upper maxilla. The salient feature of these fractures, beyond pterygoid plate involvement, is that they invariably involve the zygomatic arch, or cheek bone.
How is a Le Fort fracture diagnosed?
The symptoms of a Le Fort I fracture include swelling of the midface, a profuse nasopharyngeal bleeding, pain, malocclusion, and intraoral laceration. Fcacial elongation and facial retrusion can occur if the patient is not placed in intermaxillary fixation (IMF) and the midface is allowed to displace.
What is a 2 piece LeFort?
The 2-piece Le Fort I maxillary osteotomy begins with an incision placed just lateral to the uvula and carried anteriorly in the midline on to the hard palate ending just lateral to the midline dental gingival papillae (Fig 1). The incision of the soft palate is carried through the full thickness on the nasal side.
What is LeFort procedure?
During the LeFort I surgery, the upper jaw (or maxilla) is separated from the rest of the face and repositioned. This repositioning of the bones of the face is also called orthognathic surgery. Once separated, the upper jaw can be moved up, down, forward, backward, tilted, or turned.
