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.

How is zygomatic arch fracture diagnosed?

Zygomatic arch fractures can be clinically difficult to diagnose as the only signs may be a dimple palpable on the arch, which may or may not be tender, and or a decreased range of mouth opening. The patient’s range of mouth opening should be greater than 30 mms.

How does a zygomatic fracture happen?

Fractures of the zygomatic complex occur because of the rotation of the zygoma associated with the disarticulation of the zygomatic bone at the zygomaticofrontal suture (along the lateral orbital rim), the zygomaticomaxillary suture (medially), and along the zygomatic arch to the temporal bone (see below).

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.

Is a zygomatic fracture serious?

Highlights. Zygomatic complex fractures can involve surrounding structures and cause serious ophthalmic and aesthetic complications. Radiological investigations is very useful in diagnosing and planning the reconstruction surgery.

Can a zygomatic fracture heal on its own?

Zygomatic complex fractures with no or minimal displacement are often treated without surgical intervention, whereas fractures with functional or esthetic impairments in the form of diplopia, extraocular muscle entrapment, malocclusion, restricted mouth opening and/or depression of the malar prominence often …
