When using computer assisted surgery, the reduction (and fixation if necessary) is performed according to standard procedures as described in the AO Surgery Reference. It should be considered an adjunct to surgical treatment.
Computer assisted surgery in treating orbital fractures allows intraoperative visualization of the reconstruction using intraoperative imaging combined with image fusion of preoperative and intraoperative CT scans.
In simple orbital floor fractures radiopaque material for orbital wall reconstruction can easily be visualized by intraoperative imaging resulting in intraoperative or postoperative verification of implant placement.
With this technique, insufficient orbital reconstruction can be can be identified and corrected, eliminating the need for secondary procedures which may be necessary if only postoperative imaging is performed.
Intraoperative imaging requires an additional 10-15 min.
