How are the 3 different types of Le Fort fractures distinguished?
Le Fort I is a floating palate (horizontal) Le Fort II is a floating maxilla (pyramidal) Le Fort III is a floating face (transverse)
Which Le Fort fracture is most common?
Forces directed at the midface from straight on tend to cause LeFort I and II fractures. If the force is directed slightly downward a LeFort III fracture more frequently results (33).
How do you fix a Le Fort fracture?
Treatment of a Le Fort fracture usually requires prompt stabilization of the fracture followed by surgery, in order to restore the typical facial orientation, re-establish proper positioning of the teeth, restore involved sinus cavities, and reunify the nose and eye socket.
What bones are included in a Le Fort 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.
What test do you perform to diagnose a Le Fort I fracture?
When diagnosing Le Fort fractures, 2-D CT imaging is preferable to 3-D CT because it provides increased detail of fracture lines and associated soft tissue injuries.
What is Le Fort II fracture?
Definition. The Le Fort II fracture is also referred to as a pyramidal fracture. It commonly extends from the pterygoid plate through the maxilla, through the nasal orbital ethmoid area, and nasofrontal bone. Patients with Le Fort II injuries are often admitted to hospital unconscious and intubated.
What causes Le Fort fractures?
Le Fort fractures account for 10-20% of all facial fractures. They result from exposure to a considerable amount of force. Motor vehicle accidents (MVAs) are the predominant cause; other causes include assaults and falls.
What are Le Fort fractures?
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.
What do you need to know about Le Fort fractures?

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…
Do you need a CT scan for a Le Fort fracture?
A computerized tomography (CT) scan of the facial bones is often required to fully assess the extent of the injury.
What kind of fractures are called Lefort fractures?
The term LeFort fractures is applied to transverse fractures of the midface. Rene’ LeFort described three transverse weak lines through the midfacial skeleton as a result of his cadaver studies in 1901. Images by RosarioVanTulpe – Own work.
When to start antibiotics for a Lefort fracture?
Antibiotics with anaerobic and strep coverage should begin at admission. Violated mucosa over associated mandibular fractures or blood in the sinuses of Le Fort fracture patients may result in infections which could delay or compromise definitive treatment.
