What is LeFort III fracture?

What is LeFort III fracture?

A Le Fort III fracture includes fracture of the nasofrontal junction, bilateral fractures through the area of the frontozygomatic suture, and probable fractures of the zygomatic arch. These fractures are also referred to as craniofacial dysjunction.

What is the difference between Le Fort 1 2 and 3?

Le Fort I is a floating palate (horizontal) Le Fort II is a floating maxilla (pyramidal) Le Fort III is a floating face (transverse)

What bones are included in 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 do you treat 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 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 does Le Fort mean?

Medical Definition of LeFort 1 : a fracture of the maxilla and associated bones of the midface region: a or LeFort I : a horizontal fracture of the maxilla above the apices of the teeth. b or LeFort II : a pyramid-shaped fracture of the maxilla in which the lines of fracture meet at an apex near the bridge of the nose.

What causes LeFort fractures?

LeFort fractures most frequently result from high-speed deceleration crashes in which the midface or maxilla strike a stationary object (dashboard, pavement). These injuries may also be produced by striking the face with a rigid object (tire iron, baseball bat).

What is the most common Le Fort fracture?

How do Le Fort fractures happen?

How do you assess Le Fort fracture?

The level of a Le Fort fracture (ie, I, II, III) can often be determined by noting the structures of the midface that move in conjunction with the anterior maxilla. Illustration shows testing for mobility of the central midface. Illustration shows testing for mobility of the midface.

How is Le Fort fracture diagnosed?

Practical points

1. fracture of the pterygoid plates is mandatory to diagnose Le Fort fractures.
2. anterolateral margin of the nasal fossa involvement.
3. inferior orbital rim involvement.
4. zygomatic arch involvement.
5. nasofrontal suture involvement indicates either a type II or III fracture.
