Which bone is involved with a 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 are the surgical approaches commonly used in treatment of ZMC fractures?
Common surgical approaches to the ZMC buttresses include sublabial, lateral orbit, lower eyelid, and scalp incisions. These incisions should be used in a hierarchical fashion starting with the sublabial incision.
How do you manage a 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.
Do ZMC fractures require surgery?
The most common indication for surgery in ZMC fractures is displacement and rotation, and most displaced ZMC fractures should be treated surgically. If reduction is not performed properly, facial asymmetry will be prominent, as the result of lowering the malar prominent point [2].
What is tripod surgery?
Zygomaticomaxillary Complex Fracture (Tripod Fracture) Indications – generally aimed at realignment of mid face skeleton with restoration of relative symmetry including projection of malar eminence, as well as restoration of unrestricted motion of the globe and mandible.
What is the causes of tripod fracture?
Cause. The cause is usually a direct blow to the malar eminence of the cheek during assault. The paired zygomas each have two attachments to the cranium, and two attachments to the maxilla, making up the orbital floors and lateral walls. These complexes are referred to as the zygomaticomaxillary complex.
What is Gillies approach?
Temporal (Gillies) approach – Skin incision The Gillies technique describes a temporal incision (2 cm in length), made 2.5 cm superior and anterior to the helix, within the hairline. A temporal incision is made. Care is taken to avoid the superficial temporal artery.
What is Orif medical term?
Open reduction and internal fixation (ORIF) is a type of surgery used to stabilize and heal a broken bone. You might need this procedure to treat your broken ankle. Three bones make up the ankle joint.
What is zygomatic arch fracture?
Zygomatic arch fractures After the nasal bone, the zygoma is the second most common bone of the face to be fractured. The group at highest risk is young males. Aetiology is usually blunt trauma to the cheek, such as involved in: Assault. Road traffic accidents.
What are the common signs and symptoms of ZMC fractures?
The most common symptoms associated with ZMC fractures include pain, edema, and ecchymosis of the cheek and eyelids. Malar flattening and palpable periorbital step-offs, often occur. The traumatic force and pull of the masseter muscle may result in medial, inferior, and posterior rotation of the zygoma.
What is ZMC fracture?
Zygomaticomaxillary Complex (ZMC) fractures result from blunt trauma to the periorbital area (viz. malar eminence). ZMC fractures are also referred to as tripod, trimalar, tetrapod, quadripod, or malar fractures.
What is a tripod fracture?
Probably the most common facial fracture is the tripod or zygomaticomaxillary complex fracture, so called because it involves separation of all three major attachments of the zygoma to the rest of the face.
Can a broken jaw heal without being wired?
Have surgery performed on unstable fractures. A broken jaw may heal on its own or it may require surgery. If you have surgery, a doctor will wire your jaw to hold the jaw in place and allow the bones to heal. In some cases, screws and plates will be placed in your bones to heal your jaw. If you have surgery, it may take one or two months to heal.
What is the treatment for an impacted fracture?
The humerus is the arm bone between your shoulder and your elbow.
What is the treatment for a great toe fracture?
Rest: means not putting excessive weight on the toe and not standing for too long.
Is replantation considered a fracture treatment?
Orthodontic treatment, extrusion by surgical method, osteotomy, gingivectomy, and intentional replantation are the treatment options of an infraosseous or subgingival fracture [1]. Grossman in 1982 defined intentional replantation as follows: “a purposeful removal of a tooth and its reinsertion into the socket almost immediately after sealing the apical foramina.”
