Definition. The Le Fort II fracture is also referred to as a pyramidal fracture. It commonly extends from the pterygoid plate through the maxilla, through the nasal orbital ethmoid area, and nasofrontal bone. Patients with Le Fort II injuries are often admitted to hospital unconscious and intubated.

What is the injury that is classified as a Le Fort II fracture?

Le Fort Type II These fractures extend superiorly in the midface to include the nasal bridge, maxilla, lacrimal bones, orbital floor, and rim. They are pyramidal fractures with teeth at the base and nasal bone at the apex. These fractures are typically bilateral.

Which LeFort fracture is the most common?

Forces directed at the midface from straight on tend to cause LeFort I and II fractures. If the force is directed slightly downward a LeFort III fracture more frequently results (33).

What causes Le Fort fracture?

Le Fort fractures account for 10-20% of all facial fractures. They result from exposure to a considerable amount of force. Motor vehicle accidents (MVAs) are the predominant cause; other causes include assaults and falls.

How is a LeFort fracture treated?

Treatment of a Le Fort fracture usually requires prompt stabilization of the fracture followed by surgery, in order to restore the typical facial orientation, re-establish proper positioning of the teeth, restore involved sinus cavities, and reunify the nose and eye socket.

What is the Le Fort classification?

Le Fort I is a floating palate (horizontal) Le Fort II is a floating maxilla (pyramidal) Le Fort III is a floating face (transverse)

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.

Can you break face bones?

If you break a bone in your face, you may have minor problems or major problems. The bones affect breathing, eating and speaking. You may need surgery to get back to normal. It’s important to contact your doctor immediately if you think you have facial fractures.

How do you assess Le Fort fracture?

The level of a Le Fort fracture (ie, I, II, III) can often be determined by noting the structures of the midface that move in conjunction with the anterior maxilla. Illustration shows testing for mobility of the central midface. Illustration shows testing for mobility of the midface.

What is the maximum time that a facial wound closure can be extended?

It appears that wounds of the face and scalp can be primarily closed whenever they are seen, as long as infection is not already present. There are significant data that primary closure of other wounds can be safely done up to a maximum of 19 hours after the wound.

What is a fractured Zygoma?

From Wikipedia, the free encyclopedia. A zygoma fracture (zygomatic fracture) is a form of facial fracture caused by a fracture of the zygomatic bone. A zygoma fracture is often the result of facial trauma such as violence, falls or automobile accidents.

Which type of fracture is most likely to cause trismus?

A posterior mandibular buttress fracture, especially when associated with a displaced fracture of the condylar process or dislocation of the temporomandibular joint, can cause malocclusion and trismus.

What bones are included in a Lefort 1 fracture?

Bones fractured in a Le Fort I fracture include the lower nasal septum, the inferior portion of the pyriform apertures, the canine fossae, both zygomaticomaxillary buttresses, the posterior maxillary walls, and the pterygoid plates.

What is a LeFort procedure?

During the LeFort I surgery, the upper jaw (or maxilla) is separated from the rest of the face and repositioned. This repositioning of the bones of the face is also called orthognathic surgery. Once separated, the upper jaw can be moved up, down, forward, backward, tilted, or turned.

What is an NOE fracture?

Naso-orbito-ethmoidal (NOE) fractures are complicated fractures of mid-face structure which include nasal, lacrimal, maxillary, frontal, and ethmoid bones. The central feature of NOE fracture is displacement of the medial orbital rim with the medial canthal ligament attached.

What is a step off deformity?

If the fracture/dislocation is severe, there will be a visible and palpable “step-off”, meaning the bones are not lined up properly which can be seen and felt by the examiner. If the spinal nerves are severely compressed, there may be significant weakness and numbness in the legs.

What is a Pterygoid fracture?

The left pterygoid plates are also fractured (white arrow). The mechanism of the pterygoid fractures is likely either because of transient displacement of the mandible into the pterygoid plates or avulsion of the pterygoid plates because of distraction by the attached medial and lateral pterygoid muscles.

What is the jawbone called?

It consists of two main parts. The upper part is the maxilla. It doesn’t move. The moveable lower part is called the mandible.

What are cheekbones?

(CHEEK-bone) One of a pair of bones on each upper side of the face that forms the cheek and part of the eye socket. The cheekbones help give shape and structure to the face and are connected to the jaw and bones near the ears, forehead, and skull.

Can your nose be broken without you knowing?

When you take a blow to the nose, sometimes it’s not easy at first to determine if you’ve broken it. You could experience swelling and bruising without a break. If you have the following signs, you may have broken your nose: Serious nose pain.

What is the golden period of wound healing?

The first 6-8 hours after a wound is called the “golden period” because clinical studies show that there are less than 105 organisms/gram tissue within that time and so the wound can be closed safely.

How long is too long to close a wound?

Your risk of infection increases the longer the wound remains open. Most wounds that require closure should be stitched, stapled, or closed with skin adhesives (also called liquid stitches) within 6 to 8 hours after the injury. Some wounds that require treatment can be closed as long as 24 hours after the injury.

Which type of suture should be used to close an infected wound?

Also, in the case of an infection, the entire length of sutures would not need to come out. For rapid hemorrhage control or long wounds with minimal tension, running sutures are the best choice. They can be applied quickly and spread tension along the wound.

Can a zygomatic fracture heal on its own?

Zygomatic complex fractures with no or minimal displacement are often treated without surgical intervention, whereas fractures with functional or esthetic impairments in the form of diplopia, extraocular muscle entrapment, malocclusion, restricted mouth opening and/or depression of the malar prominence often …

What is the right zygoma?

The zygomatic bone (zygoma) is an irregularly shaped bone of the skull. It is often referred to as the cheekbone, and it comprises the prominence just below the lateral side of the orbit. The zygomatic bone is nearly quadrangular in shape and it features three surfaces, five borders and two processes.

How easy is it to break zygomatic bone?

The zygomatic bone is quite sturdy as it serves as a buttress between the skull and the maxilla. However, its prominence makes it particularly vulnerable to injury, especially when impact occurs on either side of the face. The most common cause of zygomatic fractures is violent altercation.

What portion of mandible is most commonly fractured?

The most common mandible fractures in children involve the condyle (40–70%),77 78 which is considered a primary growth center of the jaw. Direct trauma to the anterior mandible can result in proximal transmission of force, leading to injury of the mandibular condyle.

How do you tell if your chin is broken?

1. Pain in the face or jaw, located in front of the ear or on the affected side, that gets worse with movement.
2. Bruising and swelling of the face, bleeding from the mouth.
3. Difficulty chewing.
4. Jaw stiffness, difficulty opening the mouth widely, or problem closing the mouth.

What is tripod fracture?

The zygomaticomaxillary complex fracture, also known as a quadripod fracture, quadramalar fracture, and formerly referred to as a tripod fracture or trimalar fracture, has four components, three of which are directly related to connections between the zygoma and the face, and the fourth being an orbital blowout.

What is a 3 piece LeFort?

LeFort 3 distraction is surgery to reposition the cheek bones, orbits and upper jaw. “Distraction” means the bones are moves slowly over several weeks, in order to achieve a larger movement and less relapse.

Is LeFort safe?

Overall, the LeFort 1 osteotomy is a common, predictable, and safe orthognathic intervention with reliable long-term results.
