What is Le Fort fracture type 3 also known as?

1. Craniofacial disassociation

2. Malar fracture

3. Orbital fracture

4. Septal fracture

The correct answer is: Craniofacial disassociation

Le Fort fracture type 3 is commonly known as craniofacial disassociation, which denotes a severe type of facial fracture characterized by a complete separation of the facial skeleton from the cranial base. In this injury, there is typically extensive disruption to the midface structures, which may involve the orbit and the underlying skull. This type of fracture often results in significant clinical implications, including skull base instability and the potential for neurological compromise due to the detachment of the facial bones from the cranial vault. Understanding the terminology used in craniofacial injuries is crucial for effective communication among medical professionals when addressing trauma cases. The terms associated with the other options, such as malar fracture (a fracture involving the zygomatic bone) or orbital fracture (involving the bones surrounding the eye), refer to different types of facial injuries and do not encompass the broader implications of craniofacial disassociation seen in Le Fort type 3 fractures.
