ABSTRACT
This report details a technique for spheno-orbital reconstruction after meningioma
resection. The approach uses a life-size skull model generated from a thin-slice craniomaxillofacial
computed tomogram. On this skull model, the planned area of bone removal of the involved
orbit and sphenoid is outlined on the normal side opposite the lesion. A three-dimensional
implant is then generated by reversing the anticipated area of bone resection on the
normal side to create a mirror-image implant. This technique resulted in minimal intraoperative
implant contouring, decreased surgical time, and satisfactory functional and cosmetic
outcome.
