Le Fort fracture classification - Radiopaedia.org
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.

Fracture of either plate are used in clinical medicine to distinguish the Le Fort fracture classification for high impact injuries to the sphenoid and maxillary bones. The superior portion of the pterygoid processes are fused anteriorly; a vertical groove, the pterygopalatine fossa, descends on the front of the line of fusion.

Pterygoid fractures are found in all three classes of Le Fort fractures, and are the key to establishing the diagnosis. If a computed tomography (CT) reveals bilateral pterygoid fractures, a Le Fort fracture should be suspected. Conversely, if the CT scan does not reveal pterygoid fractures, the Le Fort fractures can be excluded [3].
