Treatment of complex orbito-zygomatic-maxillary fracture due to motorcycle accident

摘要

The zygomatic complex is the second part of the facial skeleton that most fracture incidence after motorcycle accidents, in losing only chip fractures of the mandible bone. Zygoma fractures can cause eye complications, paresthesias in the face, loss of anteroposterior projection, leading to bone defects that cause cosmetic and functional damage to the patient, if not treated properly. Case report: The victim of a motorcycle accident with facial trauma presented with aesthetic and functional complaints, with a conclusive diagnosis of fracture in a zygomatic complex. A hemi-coronal approach with endaural extension was performed, which allowed the visualization of fractures of the right zygomatic arch and right fronto-zygomatic suture region, transconjutival access to approach the infraorbital ridge and intraoral access to the zygomatic pillar. jaw. Fractures were reduced and fixed with 1.5mm system plates and screws. Only the zygomatic abutment was fixed with 2.0mm plates and screws. Final Considerations: Complex zygomatic bone fractures can represent a real surgical challenge. Prior planning through appropriate imaging exams is critical to defining the type of treatment and appropriate surgical access.
