Facial Fracture Management Handbook - LeFort Fractures

LeFort III fractures result in craniofacial disjunction. This is the highest level LeFort fracture and essentially separates the maxilla from the skull base. The fracture is a transverse separation of the nasofrontal suture, medial orbital wall, lateral orbital wall or zygomaticofrontal suture, zygomatic arch and pterygoid plates Le Fort III fracture The fracture line begins at the frontozygomatic suture along the lateral aspect of the internal orbit along the sphenozygomatic suture line to the inferior orbital fissure, extends medially across the floor of the orbit up the medial wall of the orbit towards the dorsum of the nose where it crosses and proceeds to the opposite side in the same manner

The third type of midface fracture is hear no evil. This represents a Le Fort III fracture. The fracture spreads laterally from the nasal bridge through the medial and lateral orbits, and then involves the zygoma. This results in complete or near complete craniofacial dislocation Fracture line - The fracture line runs below frontonasal suture from the thin middle area of nasal bones down on either side crossing the frontal process of maxilla and passes anteriorly across the lacrimal bone, immediately anterior to nasolacrimal canal

Le Fort Type II: Floating maxilla. This fracture involves extension of the fracture superiorally. Includes fractures of the nasal bridge, maxilla, lacrimal bones, and orbital floors and rims. Typically bilateral and triangular in shape. Le Fort Type III: Floating face. Rare but are considered craniofacial dysjunction Le Fort fractures rarely occur in isolation; always evaluate for other injuries. Le Fort-type fractures should be suspected if a pterygoid fracture is noted on a facial CT scan. These 3 fracture types may occur in combination either on the ipsilateral or contralateral side.

Majority of time, will see 2 or more fractures of the mandible (as opposed to a single fracture The Le Fort I fracture is a horizontal maxillary fracture with the fracture line passing from the nasal septum to the pterygoid plate, leading to a free-floating palate. The Le Fort II fracture is a pyramidal fracture from the nasal bridge crossing the orbital rim through the maxilla to the pterygoid plates, resulting in a free-floating maxilla. The LeFort II occurs along yet another weak zone in the face, and is sometimes called a pyramidal fracture because of its shape. A common mechanism is a downward blow to the nasal area. The most severe of the classic LeFort fracture complexes is the LeFort III. I suppose that this is pretty obvious, given a three-part grading system. In this. LeFort III fracture or craniofacial disjunction is a separation of all of the facial bones from the cranial base with simultaneous fracture of the zygoma, maxilla, and nasal bones. The fracture line extends posterolaterally through ethmoid bones, orbits, and pterygomaxillary suture into the sphenopalatine fossa The fracture line extends through the floor of the nose, maxillary sinus, and pterygoid plates. These fractures are associated with older patients, in whom the maxillary sinus is more developed and the permanent teeth are erupted. A Le Fort II or pyramidal fracture separates the midface from the skull. The fracture extends across the maxilla.

A Le Fort fracture is a fracture of the midface that result in the separation of all or a portion of the midface from the skull base. It is the panfacial fracture that occurs in the midfacial region and involves the maxillary bone and surrounding structures in the horizontal, pyramidal or transverse direction 3. Results. In this study, Lefort l fracture was considered in all of the patients and 4 types of plate fixation were evaluated in 2 patters of Bite force. Also they resulted that the stress was concentrated close to the fracture line on the plates and near the intersection of screw and plate just as the results in this study Patient was scanned 30 minutes after blunt trauma. Also known as Guerin's fracture or floating palate, this is an example of Le fort type I fracture with bilateral hemosinus. There is a pterygomaxillary dysjunction with fracture of the infero-medial and lateral maxillary buttress. The pterygoid plates are always involved in Le Fort fracture The incision (green line) to correct this fracture is located above the ear within the hair. A blunt instrument (kind of looks like a butter knife) is threaded through this incision down the the fracture and pushed into alignment. A patient may also have a combination of LeFort fractures (right LeFort 1 and left Lefort 3). Surgical repair.

The Le Fort classification system describes 3 common fracture lines associated with maxillary trauma and craniofacial dysjunction. These patterns were observed initially in cadaveric experiments after slow-velocity blunt trauma. In modern practice, they are rare in isolation, but elements of these fractures are commonly seen after high-velocity. 3 and 4] and the Le Fort III fracture (Break in the eye socket and bridge of the nose [Fig. of Le Fort II and Le Fort III was found in two patients and one patient had a combination of Le Fort II and Le Fort III fracture lines.

Fractures of. A Le Fort fracture of the skull is a classic transfacial fracture of the midface, involving the maxillary bone and surrounding structures in either a horizontal, pyramidal or transverse direction. The hallmark of Lefort fractures is traumatic pterygomaxillary separation, which signifies fractures between the pterygoid plates, horseshoe shaped bony protuberances which extend from the inferior.

Introduction. Midface fractures are common sequelae of motor vehicle accidents, falls, assaults, and other blunt trauma (, 1 2).Computed tomography (CT) has become the imaging standard of reference in evaluating these injuries to determine which patients will require surgical intervention for their bony injuries (, 3 4).The surgical treatment of displaced craniofacial fractures centers.

In the lateral view, arrows show possible posterior displacement of fragments from each fracture type. Adapted with permission. Lefort fracture pictures display these breakages but then again might have a number of very dangerous possibilities.

the zygomaticomaxillary suture line was seen and LeFort II fracture was diagnosed. The fracture was confi rmed as it proceeds posteriorly through the nasal septum and pterygoid plates. Neurosurgery and anaesthetic fitness was obtained to carry out the surgery. The patient was operate A 3-D CT reconstruction showing a LeFort type 1 fracture ( fracture line is marked by an arrow ) Diagnosis is made based on physical exam findings with confirmation by axial CT. The patient is taken for radiography of the head and neck then after obvious fracture signs the patient is taken to CT scan for more specific anatomic information Normal nasal bone anatomy The next set of fractures in this rogue's gallery of common facial fractures are the LeFort complexes.These are complex bilateral fractures associated with a large unstable fragment (floating face) and invariably involve the pterygoid plates.LeFort studied fracture patterns produced in cadavers. He found three main planes of weakness in the face, which correspond.

These included: (1) a separation of the face from the cranium (i.e. LeFort III fracture), (2) a separation of the mid-portion of the face (i.e. LeFort II fracture), and (3) Gurrin's fracture (LeFort I fracture) (Tilson et al., 1972). The LeFort III 'line of weakness' was described as beginning in the region of the nasal bones, passing towards. complex fracture, a LeFort II fracture and a subcondylar fracture of the right mandible that were sustained in a mo-torcycle accident. The patient was hospitalized in the plastic surgery department and open reduction was performed on the nasoethmoidal complex and maxilla using an absorbable plate. No treatment was performed for the subcondylar. LeFort I fracture, this fracture line passes beneath the zygomatic buttress, then, traversing the pterygomaxillary fissure at a higher level and fracturing the pterygoid laminae approximately midway from its base at the same time fracturing the palatine bones and nasal septum. Separation of the entire pyramidal block from the base of the skull i - Radiating fracture lines - Ends tend to be angled and jagged - May show staining from hematoma - Fracture margin should be the same color as the rest of the bone.
