Zygoma, isolated zygomatic arch

A pure zygomatic arch fracture should be suspected in a patient who has pain, swelling, or a palpable step-off along the zygomatic arch, but no other findings in the area of the zygomaticofrontal area or the inferior orbital rim. Another common sign is trismus.

The diagnosis of a pure zygomatic arch fracture can readily be confirmed on an axial CT.
