Virtual zygoma reduction

Virtual simulation of the zygoma reduction is performed by mirroring the unaffected contralateral zygoma after auto segmentation. The purple line shows the outer surface of the virtually repositioned zygoma and becomes the surgical goal for reduction.

In this specific case, the virtual zygoma reduction indicates a displaced fracture of the paranasal buttress (arrow). This may be missed in the preoperative examination, leading intraoperatively to malpositioning of the zygoma.
