What is a Zygomaticomaxillary complex 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: the lateral orbital wall (at either the zygomaticofrontal suture superiorly along the wall or zygomaticosphenoid suture inferiorly)

The term ZMC fracture describes a spectrum of injuries that includes nondisplaced fractures, fractures displaced at an isolated buttress, and severely comminuted fractures with bone loss.

Also Know, which cheek bones are involved in a malar complex fracture? The zygoma forms part of the floor and lateral wall of the orbit and the zygomatic arch is an important feature in the structure and appearance of the face. The malar complex refers to the zygoma and maxillary bones (and therefore forms part of the orbital floor and lateral orbital wall).

Then, what is the treatment for zygomatic fracture?

Surgical intervention is an effective treatment modality of depressed zygomatic complex fractures, whereas a nonsurgical approach is often used for nondisplaced fractures. Most zygomatic complex fractures can be treated solely by an intraoral approach and rigid fixation at the zygomaticomaxillary buttress.

Where is a zygomatic fracture?

Fracture of the zygomatic bone is a common fracture of the facial skeleton; the zygomatic bone forms the most anterolateral projection one on each side of the middle face. The zygomatic bone is attached to the maxilla at the zygomaticomaxillary (ZM) suture and alveolus forming the zygomaticomaxillary buttress.

How long does a zygomatic fracture take to heal?

Healing time for facial fractures Facial bruising and swelling may be cleared up in only 2-3 weeks. Nerve damage affecting physical sensation may take weeks or months to heal, and in some cases it may only partial heal or there may even be no recovery at all.

What are the symptoms of a broken cheekbone?

What are the signs and symptoms of a facial fracture? Pain, swelling, or bruises. Headache. Tingling or numbness. Swollen or flattened cheek. Blurry vision, double vision, or seeing floaters (spots) Decreased eye movement or pain when you move your eyes. Eyes that are sunken or not in the normal position, or swollen eyelids.

What is an orbital floor fracture?

An orbital blowout fracture is a traumatic deformity of the orbital floor or medial wall, typically resulting from impact of a blunt object larger than the orbital aperture, or eye socket. They can occur with other injuries such as transfacial Le Fort fractures or zygomaticomaxillary complex fractures.

Which complication can result from a Zygoma fracture?

Malunion is the most common complication of zygomatic fractures and is the result of improper reduction and fixation, resulting in malocclusion, facial asymmetry, and enophthalmos. Extraocular muscle entrapment, although usually attributable to the initial fractures, also can occur secondary to fracture repair.

What is malar eminence?

Anatomical terms of bone The zygomatic process of the maxilla (malar process) is a rough triangular eminence, situated at the angle of separation of the anterior, zygomatic, and orbital surfaces. In front it forms part of the anterior surface. Behind it is concave, and forms part of the infratemporal fossa.

What does open reduction internal fixation mean?

Definition. An open reduction and internal fixation (ORIF) puts pieces of a broken bone into place using surgery. Screws, plates, sutures, or rods are used to hold the broken bone together.

What do you do for a broken cheekbone?

Cheekbone fractures usually heal without infection but it may be necessary to give you antibiotics, particularly if a “graft” has been used. Initially it may be necessary to give you antibiotics through a vein in your arm whilst you are in hospital.

What is maxillofacial trauma?

Facial trauma, also called maxillofacial trauma, is any physical trauma to the face. Facial trauma can involve soft tissue injuries such as burns, lacerations and bruises, or fractures of the facial bones such as nasal fractures and fractures of the jaw, as well as trauma such as eye injuries.

Can you fly with facial fractures?

There are no clear, evidence-based guidelines that dictate when it is safe for a patient to fly after a midface fracture, whether they are surgically managed or not. The Royal Darwin Hospital Maxillofacial Unit had 48 out of 201 patients with a midface fracture flown to the unit for definitive management.

How is a maxillary fracture treated?

Treatment of maxillary fractures Surgery typically involves fixation with screws and plates. After surgery, the jaws may need to be immobilized but often for only a few days, after which people should eat only soft foods for several weeks.

What are facial fractures?

A facial fracture is a broken bone in the face. The face has a complex bone structure. The facial skeleton consists of the frontal bone (forehead), zygomas (cheekbones), orbital bones (eye sockets), nasal bones, maxillary bones (upper jaw) and mandible (lower jaw). Fractures to other facial bones can also occur.

What bones make up the cheekbone?

Zygomatic bone, also called cheekbone, or malar bone, diamond-shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek. It adjoins the frontal bone at the outer edge of the orbit and the sphenoid and maxilla within the orbit.

What is a maxillary sinus fracture?

Maxillary fracture is defined as partial or full separation of parts or the entire tooth-bearing part of the maxilla from the residual midface or the neurocranium. From: Maxillofacial Surgery (Third Edition), 2017.

What are Zygomas?

From Wikipedia, the free encyclopedia. The term zygoma generally refers to the zygomatic bone, a bone of the human skull commonly referred to as the cheekbone or malar bone, but it may also refer to: The zygomatic arch, a structure in the human skull formed primarily by parts of the zygomatic bone and the temporal bone.
