What is closed fracture of zygomatic arch?
Fractures of the ZMC or zygomatic arch can often lead to unsightly malar depression, which should be corrected to restore a normal facial contour. ZMC fractures can also cause significant functional issues, including trismus, enophthalmos and/or diplopia, and paresthesias of the infraorbital nerve.
What is the zygomatic fracture?
A zygomatic complex fracture is a fracture that involves the zygoma and its surrounding bones. The typical lines of a zygomatic complex fracture are: A fracture emanating from the inferior orbital fissure superiorly along the sphenozygomatic suture to the frontozygomatic suture where it crosses the lateral orbital rim.
What is a tripod 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 an orbital blowout.
How long does a zygomatic fracture take 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.
How long does it take for a zygomatic fracture to heal?
Even if a fracture is held in place with plates and screws it still takes approximately six weeks for your cheekbone to heal completely. During this recovery period, you will need to be careful to avoid an injury to this area of your face, as it may cause the cheekbone to move out of position.
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.
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 bones are in a tripod fracture?
Zygomaticomaxillary complex (ZMC) fractures, also known as 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.
- lateral orbital rim.
Where is a tripod fracture located?
What bones are involved in 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.
When to use closed treatment for zygomatic fractures?
1. Principles Closed treatment of fractures of the zygomatic complex refers to the management of fractures of the zygomatic complex where, either prior to or following the reduction of the zygoma, the patient does not have a significant orbital defect.
Can a fracture of the zygomatic arch occur in isolation?
Fractures of the zygomatic arch can occur in isolation. In such cases, the tetrapod articulations are usually not violated and the remainder of the complex is stable. This chapter focuses on closed reduction and treatment options for isolated zygomatic arch fractures.
How to treat zygomatic arch in the mouth?
A soft toothbrush (dipped in warm water to make it softer) should be used to clean the surfaces of the teeth and arch bars. Elastics are removed for oral hygiene procedures. Chlorhexidine oral rinses should be prescribed and used at least 3 times a day to help sanitize the mouth.
