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.

Keywords: Computer model; custom cranial implant; spheno-orbital reconstruction; “reversed implant”
