What is Le Fort 2 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 is Le Fort 4 fracture?
Le Fort I fracture (horizontal), otherwise known as a floating palate, may result from a force of injury directed low on the maxillary alveolar rim, or upper dental row, in a downward direction.
Can Le Fort fractures be unilateral?
These can be unilateral or bilateral. These fractures extend superiorly in the midface to include the nasal bridge, maxilla, lacrimal bones, orbital floor, and rim. They are pyramidal fractures with teeth at the base and nasal bone at the apex. These fractures are typically bilateral.
How many types of LeFort fractures are there?
There are three types of Le Fort fractures.
What kind of fracture is Le Fort I?
The Le Fort I fracture is a horizontal maxillary fracture with the fracture line passing from the nasal septum to the pterygoid plate, leading to a free-floating palate.
Where does a Lefort fracture in the face go?
The fracture is a transverse separation of the nasofrontal suture, medial orbital wall, lateral orbital wall or zygomaticofrontal suture, zygomatic arch and pterygoid plates. Within the posterior orbit LeFort III fractures may pass through the inferior or superior orbital fissure and in rare situations through the optic canal.
How did Rene le Fort describe facial fractures?
The Le Fort classification system attempts to differentiate midfacial fractures, which account for up to 20% of all facial fractures. In 1901, René Le Fort described three predominant midfacial injury patterns. Each type involves separation of a portion of the midface from the skull base.
How are Lefort 3 and cranial base fractures related?
The force is usually applied from the lateral direction with a severe impact. Many of time lefort 3 fracture seen in combination with lefoer 1 & 2 or cranial base fracture. SWELLING After a facial injury, inflammatory exudates accumulates to protect the injured tissue.
