Check for any signs of reduced mouth opening.Assess sensation by checking the branches of the trigeminal nerve.Palpate the face for any area of acute bony tenderness or bony steps.The patient should be assessed by an emergency department clinician to clear them of a head injury.If it is compromised, the patient may require intubation Make sure the airway is patent and not compromised.Fracture extends through the nasofrontal suture, medial and lateral orbital walls, zygomaticofrontal suture, zygomatic arch and pterygoid plates.Separation of the maxilla from the base of the skull.Le Fort III Image produced by AO displaying Le Fort III fracture pattern Extends from the anterior portion of the medial orbital walls, orbital floor, inferior orbital rims to the posterior maxilla and pterygoid plates.Le Fort II Image produced by AO displaying Le Fort II fracture pattern Results in separation of the hard palate from the maxilla.Fracture line runs through the maxilla and the pterygoid plates at the level of the nasal floor.Figure 1: Le Fort fracture classification Le Fort I Image produced by AO displaying Le Fort I fracture pattern In addition, Le Fort injuries are not overly common but do occur, usually as a result of severe blunt force trauma to the face. Consequently, they may also cause a dental malocclusion. Le Fort fractures result in a separation of the maxilla from the rest of the skull. Each are them are determined by the levels of the transverse fractures (Figure 1). He assessed predictable patterns of fracture of the midface and ultimately described three lines of weakness.Īs a result, this is known as the Le Fort classification and is divided into Le Fort I, Le Fort II or Le Fort III. It was based on his studies conducted on cadavers. In 1901 French surgeon Rene LeFort published a classification of midface fractures. This month, Hannah Hook explores Le Fort fractures, including classifying each one and the best treatment option for the patient. A Dental Student’s Guide to…Le Fort fractures
