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.

Why is LeFort done?

LeFort 1 osteotomy with horizontal advancement is used for the majority of patients to correct their malocclusion. This surgery is commonly performed in the last stages of treatment for patients with cleft lip and palate. They have significant class III malocclusion as well as a narrow dental arch and palatal collapse.
