A zygomatic fracture is a break involving the cheekbone and surrounding facial structures.
Symptoms may include cheek pain, swelling, bruising, flattening of the cheek, double vision, numbness over the cheek or upper lip, and difficulty opening the mouth fully.
Imaging helps confirm the fracture, show whether the cheekbone has moved out of place, and check whether the eye socket or nearby facial bones are involved.
CT of the facial bones is often the most useful test because it shows the fracture pattern and displacement clearly.
Treatment depends on displacement, symptoms, and eye or facial involvement and may range from observation to facial surgery.
