3Intraoperative assessment of reduction

The correct anatomic shape of the orbital floor can be verified after zygoma reduction in the intraoperative CT scan when virtual reconstruction in the preoperative CT scan is transferred to the intraoperative scan via image fusion. Note how the orbital floor after zygoma reduction perfectly fits the planned position (green). This confirms that there is no need for orbital wall reconstruction in this case.

Due to intraoperative visualization using a 3D C- arm after zygoma reduction, unnecessary orbital reconstructions can be avoided.

In case the orbital floor is not properly reduced, open orbital revision is recommended.
