In short. Cheekbone fracture repair explained: how zygomatic fractures are assessed, when surgery is needed, how the bone is repositioned and fixed, and the real recovery and risks.
Key points
- Facial fractures are easiest to reposition in the first one to two weeks, before early healing begins to set the fragments.
- Delay does not make the operation impossible, but it makes it longer, less predictable, and more likely to need a bone graft or an implant to fill a gap.
- An injury that changes the bite, vision or facial shape needs prompt assessment.
The cheekbone, or zygoma, is the buttress that gives the middle of the face its width and protects the eye. A fracture here is one of the most common facial injuries, usually from a fall, a road collision, or a blow during sport. The bone rarely breaks in one place: it separates at its attachments, so the whole complex rotates or displaces.
How it is assessed
The examination looks for flattening of the cheek, a step in the lower eye socket rim that can be felt through the skin, blood in the lining of the upper gum, and altered sensation over the cheek, side of the nose and upper lip — a sign that the nerve running through the bone has been bruised. Eye position is checked carefully: a fracture that displaces the orbital floor can let the eye sit lower, cause double vision, or trap the muscle that moves the eye upward. A CT scan of the face is the standard imaging study, and it shows the displacement and the state of the eye socket clearly.
When surgery is needed
Not every cheekbone fracture requires an operation. A fracture with no displacement, a normal bite, free eye movement and no cosmetic flattening may be treated by observation while it heals. Surgery is considered when the cheek is visibly flattened, when the bite has changed because the bone supports the upper jaw, when there is double vision or a trapped eye muscle, or when the eye socket is enlarged enough that the eye sits low.
Timing matters more than technique
Facial fractures are easiest to reposition in the first one to two weeks, before early healing begins to set the fragments. Delay does not make the operation impossible, but it makes it longer, less predictable, and more likely to need a bone graft or an implant to fill a gap. An injury that changes the bite, vision or facial shape needs prompt assessment.
How the repair is done
The bone is repositioned through small incisions placed in hidden areas — inside the mouth, in the lower eyelid crease, and in the hairline where needed. Once it is back in position, the fragments are held with small titanium plates and screws that are strong enough to keep the shape while the bone unites. Where the eye socket floor is broken, a thin sheet of material rebuilds it so the eye returns to its level and moves freely.
Recovery and honest risks
Swelling over the cheek and around the eye is marked for the first week and settles over several weeks. Numbness of the cheek and upper lip is common and usually improves over months, though a patch may remain permanently. Double vision can persist after surgery if the eye muscles were injured. Infection, palpable plates, residual flatness of the cheek and the possibility of a second operation are recognised outcomes. The final contour is judged at six to twelve months.
Seek urgent assessment if
- You have double vision, or one eye sits lower or cannot move in the same direction as the other.
- Numbness covers the cheek, side of the nose and upper lip, or the cheek is visibly flattened after a blow.
- The bite no longer meets, or opening the mouth is limited and painful after facial injury.
Frequently asked questions
Does every cheekbone fracture need an operation?
No. A fracture with no displacement, a normal bite, free eye movement and no cosmetic flattening may be treated by observation while it heals. Surgery is considered when the cheek is visibly flattened, the bite has changed, there is double vision or a trapped eye muscle, or the eye socket is enlarged enough that the eye sits low.
Why does timing matter after a cheekbone fracture?
Facial fractures are easiest to reposition in the first one to two weeks, before early healing begins to set the fragments. Delay does not make the operation impossible, but it makes it longer, less predictable, and more likely to need a bone graft or an implant to fill a gap.
How is a cheekbone fracture repaired?
The bone is repositioned through small incisions in hidden areas — inside the mouth, in the lower eyelid crease, and in the hairline where needed — then held with small titanium plates and screws while the bone unites. Where the eye socket floor is broken, a thin sheet of material rebuilds it.
Risks & Limitations
- Reconstruction is usually staged — more than one operation is normal, and the plan may change as healing progresses.
- Donor-site scarring and discomfort, including after rib cartilage harvest.
- Partial or complete failure of a flap or graft, which may require further surgery.
- Scars are permanent. They mature and fade but never disappear.
- Asymmetry and the inherent limits of matching a normal side.
- Altered sensation, numbness or weakness in the operated area.
- Contracture, which may need release procedures later.
- Final assessment is made at 6–12 months, and longer in growing children.
When to Seek Care
- A flap or graft that turns dark, cold, black or stops bleeding when pricked.
- Fever above 38 °C, or spreading redness, warmth or discharge around a wound.
- New or worsening pain, swelling or fluid leakage from the operative site.
- Bleeding that does not stop with gentle pressure.
- Any change in a reconstructed area that concerns you, however minor.
