Causes and Risk Factors

Understanding the causes and risk factors can help in prevention and management.

Traumatic injuries from falls, accidents, or physical altercations.
Sports-related injuries, particularly in contact sports.
Pre-existing conditions that weaken bone structure, such as osteoporosis.

Diagnostic Tests Before Procedure

Several diagnostic tests may be performed to confirm the need for surgery.

X-rays to visualize the fracture and assess displacement.
CT scans for detailed imaging of the facial bones.
Physical examination to evaluate symptoms and facial structure.

Procedure Description

The open reduction procedure involves several key steps.

Administer anesthesia to ensure patient comfort.
Make an incision in the skin near the zygomatic arch.
Carefully reposition the fractured bone fragments into their correct alignment.
Secure the bone using plates, screws, or wires as necessary.

Follow-up appointments to monitor healing and remove sutures.
Pain management with prescribed medications as needed.
Limit physical activity for several weeks to allow proper healing.
