Impacted type of fractures may be almost immobile and it is only by grasping the maxillary teeth and applying a little firm pressure that a characteristic grate can be felt which is diagnostic of the fracture.

Percussion of upper teeth results in cracked pot sound. Le Fort II and Le Fort III common — Gross edema of soft tissue over the middle third of the face, bilateral circumorbital ecchymosis, bilateral subconjunctival hemorrhage, epistaxis, CSF rhinorrhoea, dish face deformity, diplopia, enophthalmos, cracked pot sound.

Le Fort II — Step deformity at infraorbital margin, mobile mid face, anesthesia or paresthesia of cheek. Le Fort III — Tenderness and separation at frontozygomatic suture, lengthening of face, depression of ocular levels enophthalmos , hooding of eyes, and tilting of occlusal plane, an imaginary curved plane between the edges of the incisors and the tips of the posterior teeth.

As a result, there is gagging on the side of injury. This finding can be inconsistent due to the midfacial bleeding and swelling that typically accompany such injuries, and so confirmation is usually needed by radiograph or CT. As the classification increases, the anatomic level of the maxillary fracture ascends from inferior to superior with respect to the maxilla: 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.

The essential component of these fractures, in addition to pterygoid plate involvement, is involvement of the lateral bony margin of the nasal opening. They also involve the medial and lateral buttresses, or walls, of the maxillary sinus , traveling through the face just above the alveolar ridge of the upper dental row. At the midline, the inferior nasal septum is involved. In addition to pterygoid plate disruption, their distinguishing component is involvement of inferior orbital rim.

When viewed from the front, the fracture is classically shaped like a pyramid. It extends from the nasal bridge at or below the nasofrontal suture through the superior medial wall of the maxilla, inferolaterally through the lacrimal bones which contain the tear ducts, and inferior orbital floor through or near the infraorbital foramen. The salient feature of these fractures, beyond pterygoid plate involvement, is that they invariably involve the zygomatic arch , or cheek bone.

These fractures begin at the nasofrontal and frontomaxillary sutures and extend posteriorly along the medial wall of the orbit, through the nasolacrimal groove and ethmoid air cells. The sphenoid is thickened posteriorly, limiting fracture extension into the optic canal. Instead, the fracture continues along the orbital floor and infraorbital fissure, continuing through the lateral orbital wall to the zygomaticofrontal junction and zygomatic arch.

Within the nose, the fracture extends through the base of the perpendicular plate of the ethmoid air cells, the vomer , which are both part of the nasal septum. As with the other fractures, it also involves the junction of the pterygoids with the maxillary sinuses. CSF rhinorrhea , or leakage of the nutrient laden fluid that bathes the brain, is more commonly seen with these injuries due to ethmoid air cell disruption, as the air cells are located immediately beneath the skull base.

First a frontal bar is used, which refers to the thickened frontal bone above the frontonasal sutures and the superior orbital rim. The facial bones are suspended from the bar by open reduction and internal fixation with titanium plates and screws, and each fracture is fixed, first at its superior attachment to the bar, then at the inferior attachment to the displaced bone.

For stability, the zygomaticofrontal suture is usually replaced first, and the palate and alveolar ridge are usually fixed last. Finally, after the horizontal and vertical maxillary buttresses are stabilized, the orbital fractures are fixed last.
