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.
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 a Le Fort 3 fracture?
A Le Fort III fracture includes fracture of the nasofrontal junction, bilateral fractures through the area of the frontozygomatic suture, and probable fractures of the zygomatic arch. These fractures are also referred to as craniofacial dysjunction.
What causes a 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 many types of LeFort fractures are there?
There are three types of Le Fort fractures.
What is the maximum time 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.
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.
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.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.

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 Panfacial fracture?
INTRODUCTION. Panfacial bone fractures are defined as facial fractures simultaneously involving the upper, middle, and lower thirds of the face. Fractures of the frontal bone, maxilla, zygomatic complex, nasoethmoid-orbital (NEO) region, and mandible are the most common [1,2,3].
What is a Lefort 4 fracture?
Le Fort I level fractures are essentially a separation of the hard palate from the upper maxilla due to a transverse fracture running through the maxilla and pterygoid plates at a level just above the floor of the nose.
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 Zygoma bone?
The zygomatic bone (or zygoma) is a paired, irregular bone that defines the anterior and lateral portions of the face. The zygomatic complex is involved in the protection of the contents of the orbit and the contour of the face and cheeks.[1]
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.
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 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.
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 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?
- Pain in the face or jaw, located in front of the ear or on the affected side, that gets worse with movement.
- Bruising and swelling of the face, bleeding from the mouth.
- Difficulty chewing.
- Jaw stiffness, difficulty opening the mouth widely, or problem closing the mouth.
What is tripod fracture?
tri·pod frac·ture. a facial fracture involving the three supports of the malar prominence, the arch of the zygomatic bone, the zygomatic process of the frontal bone, and the zygomatic process of the maxillary bone.
What is the fastest way to recover from jaw surgery?
- Drink your meals.
- Add easy-to-chew foods.
- Keep pain under control.
- Take care of your lips.
- Give yourself the recovery time you need.
Is LeFort safe?
Overall, the LeFort 1 osteotomy is a common, predictable, and safe orthognathic intervention with reliable long-term results.
How long does LeFort surgery take?
Routine surgery on one jaw typically takes one to two hours. Surgery that involves multiple procedures may take as long as three to five hours.
What is Fort Colpocleisis?
Introduction and hypothesis: LeFort colpocleisis is a minimally invasive surgical option for patients with pelvic organ prolapse who no longer desire sexual activity. Pelvic surgeons have limited exposure to this procedure during their training, and are therefore less likely to offer this procedure to their patients.
Which is the first fracture repaired in a patient with Panfacial fracture?
The first priority is to address any significant calvarial, frontal sinus, and orbital roof fractures. Using the calvarium as the foundation for the remainder of the midface reconstruction, the surgeon progresses from this level down to the Le Fort I level.
What is submental intubation?
[4] Submental intubation technique consists of passing the tube through the anterior floor of mouth, allowing free intraoperative access to oral cavity and nasal pyramid without endangering patients with skull base trauma.

The primary bones of the face are the mandible, maxilla, frontal bone, nasal bones, and zygoma. Facial bone anatomy is complex, yet elegant, in its suitability to serve a multitude of functions.
