Objective:
Generally, a wide exposure of the buttress and separation of the zygoma fracture segments from the adjacent soft tissue and muscle are recommended for zygomatic and infraorbital rim fractures. However, increased soft tissue complications, including cheek drooping, make the extent of the dissection smaller. We propose a useful technique for zygomatic and maxillary fracture reduction with minimal dissection and less soft tissue injury.
Methods:
Between 2007 and 2008, a total of 41 patients with a diagnosis of zygomatic or isolated infraorbital rim fractures were reviewed retrospectively. One or 2 intermaxillary fixation screws and 24-gauge wires were applied to the exposed fracture segments without wide dissection. By pulling the wire with changing the vector to generate reduction force opposite direction to initially applied injury, we reduced the fracture fragment easily and successfully.
Results:
No associated complication resulting from this method was observed.
Conclusions:
The advantages of our technique include easily controllable reduction vector, smaller dissection extent, and less injury to operation field compared with conventional methods.
