Intraoperative Navigation-assisted Surgical Orbital Floor Reconstruction in Orbital Fracture Treatment: A Case Report

その他

The main goal of three-dimensional reconstruction of the orbital wall fracture is restoration of the original orbital volume. Although orbital reconstruction using implant materials is effective, it is difficult to assess the accuracy during surgery. Additionally, complete reconstruction of the orbital floor is difficult in patients with massive comminution. Therefore, a conventional technique that preoperatively creates orbital reconstruction materials on the basis of individually precise model reproductions of the orbital forms was developed. However, this method was limited because custom-made preparation and fabrication of the pre-bending plate is time consuming, making it inapplicable during emergencies. On the other hand, computer-assisted intraoperative navigation systems have recently evolved to improve precision and simplify the surgical procedure, resulting in improved execution and predictability. Here we describe our feasible application of an intraoperative navigation-assisted orbital floor reconstruction using the mirroring technique in orbital fracture treatment.
