How do you treat a zygomaticomaxillary complex 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.
What is a orbital Quadripod 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 the orbital floor.
When do you use ZMC fracture?
Surgical indications for concomitant orbital fractures include significant fractures of the inferior orbital rim, orbital floor defects greater than 2 cm2, and significant posterior displacement (> 1 cm2) of the ZMC body.
What is maxillary complex?
The zygomaticomaxillary complex (ZMC) plays a key role in the structure, function, and aesthetic appearance of the facial skeleton. It provides normal cheek contour and separates the orbital contents from the temporal fossa and the maxillary sinus.
What is a maxillary fracture?
A maxilla fracture happens when the maxilla becomes cracked or broken. This often happens due to injuries to the face, such as from falling, a car accident, getting punched, or running into an object. These injuries can be significant.
What is a zygomatic complex fracture?
Zygomaticomaxillary complex (ZMC) fractures, also known as a tripod, tetrapod, quadripod, malar or trimalar fractures, are seen in the setting of traumatic injury to the face. They comprise fractures of the: zygomatic arch. inferior orbital rim, and anterior and posterior maxillary sinus walls.
What is zygomaticomaxillary complex (ZMC)?
The Zygomaticomaxillary complex (ZMC) is a 3-dimensional structure which defines midface width and projection, as well as providing shape to the orbit. Zygomaticomaxillary complex (ZMC) fractures refer to the disruption of 4 buttresses in the malar eminence. There are four points of fixation of the zygoma
What are the suture fractures of the zygomatic arch?
fracture of the zygomatic arch and/or diastasis of the temporozygomatic suture fractures of the inferior orbital rim and anterior and posterior maxillary sinus walls and/or diastasis of the zygomaticomaxillary suture fracture of the lateral orbital rim and/or diastasis of the frontozygomatic suture Treatment and prognosis
Is the zygoma a tripod fracture?
This fracture is sometimes referred to as a “tripod fracture”, but this is a misnomer. The zygoma has articulations with frontal, maxillary, and temporal bones, as well as greater wing of the sphenoid. It should be called a ‘tetrapod’ 19.20. The Zygoma serves as a muscular insertion point of the: Masseter: elevates and protudes the mandible.
