Recovery Expectations After Zygomaticomaxillary Complex (ZMC) Fracture Repair

While not a guarantee for an individual's experience, this description may inform you on the usual recovery timeline after open reduction and internal fixation of a zygomaticomaxillary complex (ZMC) fracture.

 

Recovery after ZMC fracture repair (putting the broken cheekbone back into position and holding it with small titanium plates and screws) is usually steady and predictable. Many patients go home the same day or after one night. Most return to desk work or school in about 1–2 weeks, while the bones take about 6 weeks to heal enough for most normal stresses, and contact sports are usually avoided for about 6–8 weeks or longer. Recovery is longer when the floor of the eye socket (orbital floor) also needed repair. Incisions are commonly placed inside the mouth above the upper teeth, in or below the lower eyelid, and/or near the outer eyebrow, so visible scars are usually small.

Immediate Postoperative Period (Day 0–2)

Swelling and bruising of the cheek and around the eye are expected and usually peak at about 48–72 hours. The eye on that side may be swollen partly closed. Pain is usually moderate and managed with acetaminophen and ibuprofen when allowed, sometimes with a short course of opioid medicine. Sleep with the head elevated and apply cold compresses to reduce swelling. Antibiotics and a mouth rinse may be prescribed, especially when incisions are inside the mouth. Do not blow your nose, and sneeze with your mouth open, particularly if the orbital floor or sinus was involved, because air can be forced into the tissues around the eye. Vision is checked after surgery.

First Week (Days 1–7)

Swelling begins to go down after the third day. A soft diet that needs little chewing is recommended; avoid chewing hard foods on the repaired side. Rinse the mouth after meals and brush gently, avoiding any incision inside the mouth. Keep skin incisions clean as instructed. Avoid heavy lifting, bending, strenuous exercise, and any pressure on the cheek, including sleeping on that side and wearing heavy glasses that rest on the cheek. Your first follow-up visit is typically at about 1 week, when skin stitches, if present, may be removed.

Weeks 2–4

Most visible swelling and bruising fade by 2–3 weeks, although subtle puffiness can last longer. Most patients return to work or school in this window. Continue a soft diet and avoid chewing hard foods on the repaired side for about 6 weeks or as your surgeon advises. Light exercise such as walking can usually be resumed, but avoid any activity that risks a blow to the face.

Months 1–3 / Long-Term

Bone healing is generally solid by about 6–8 weeks, after which most activities can be resumed, with contact sports usually delayed until cleared and sometimes with a protective face shield. Numbness of the cheek, side of the nose, upper lip, and upper teeth on the injured side is very common because the infraorbital nerve (which supplies feeling to these areas) is often bruised by the fracture itself. Feeling usually improves over 3–12 months, but some patients have lasting partial numbness. The plates and screws are normally left in place permanently and rarely need removal. Final swelling resolution and cheek contour are usually judged at about 3–6 months.

When to Seek Urgent Attention

Contact your surgeon promptly, or seek emergency care, for:

  • Decreasing vision, severe eye pain, a bulging eye, or inability to move the eye (possible bleeding behind the eye, rare but an emergency; seek emergency care immediately)

  • New or worsening double vision

  • Fever over 101°F, increasing redness, swelling, or pus from an incision or inside the mouth (infection, reported in about 2–4%)

  • Swelling around the eye that suddenly increases after nose blowing or sneezing

  • A lower eyelid that pulls down or does not close well, or ongoing eye dryness or tearing (eyelid position changes can follow lower-lid incisions)

  • Teeth that suddenly do not fit together normally
