What bones are in a tripod fracture?
Pertinent anatomy: Buttresses: two major buttresses of the ZMC are the upper transverse maxillary (across the zygomaticomaxillary and zygomaticotemporal sutures) and the lateral vertical maxillary (across the zygomaticomaxillary and frontozygomatic sutures)
How do you get a tripod fracture?
They are the second most common facial bone fracture after nasal bone injuries. The fracture complex results from a direct blow to the malar eminence and results in three distinct fracture components that disrupt the anchoring of the zygoma.
What is a displaced tripod fracture?
A tripod fracture is a facial fracture that involves the zygoma, which is displaced. It may involve the arch and the orbit.
What causes a zygomatic fracture?
Zygoma fractures usually result from high-impact trauma. Leading causes of fractures include assault, motor vehicle or motorcycle accidents, sports injuries, and falls.
How is a zygomatic fracture treated?
Most zygomatic complex fractures can be treated solely by an intraoral approach and rigid fixation at the zygomaticomaxillary buttress. Further exposure of the zygomaticofrontal junction or inferior orbital rim is necessary for severely displaced fractures, which require additional fixation.
Does tripod fracture need surgery?
Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie’s approach is used for depressed zygomatic fractures. The prognosis of tripod fractures is generally good.
What is a tripod facial 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.
What is maxillofacial trauma?
Maxillofacial trauma is any injury to the face or jaws. Facial trauma may present with skin lacerations, burns, obstruction to the nasal cavity or sinuses, damage to the orbital (eye) sockets, fracture to the jawbone, and missing or broken teeth.
How long does it take for facial fracture to heal?
They will heal themselves over 3-6 weeks. want to bring the broken bones back into a normal alignment (called ‘reducing’ the fracture) and keep it/them in this place (called ‘fixing the fracture’), preventing further injury. Sometimes they will need to operate to do this.
How do you fix a zygomatic fracture?
What are the symptoms of zygomatic fracture?
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.
