PURPOSE: The purpose of this study is to describe the usefulness of intraoperative mobile CT scans in the reduction of zygomatic arch fracture. Method: Two patients with zygomatic arch fractures were selected who were indications of closed reduction by Gilles' approach. After the reduction was done in the operating room with zygomatic arch elevator, intraoperative CT scan was done to check the extent of reduction. Additional reduction was performed according to the obtained images from the intraoperative mobile CT scan. Examination of the preoperative CT, intraoperative CT after the reduction, and postoperative plain X-ray films were done for documentation and analysis.
Reduction was carried out successfully to the patients without any complications. Both patients were satisfied with the postoperative cosmetic and functional outcome. Revisional surgery was not necessary during the 6 months follow up.
The advantage of this method is that it is easier to obtain three dimensional relationships of the fracture site. Furthermore, the operator is less exposed to radiation hazards compared to other methods that obtain intraoperative images such as the C-arm. In conclusion, intraoperative mobile CT scan can be a useful surgical aid in the reduction of zygomatic arch fractures.
