Reconstruction of the Orbit after Resection of Spheno-Orbital Meningiomas: A Novel Technique

Abstract

Background: Spheno-orbital meningiomas (SOMs) are complex tumors involving the middle cranial fossa and orbit. With improvement in microsurgical techniques, total or near-total resection of these tumors is increasingly possible, but reconstruction of the orbit remains challenging. Inadequate reconstruction may lead to cosmetic deformities, persistent exophthalmos or enophthalmos, or limited extraocular motility. Traditional methods of reconstruction involve the use of bone autograft, titanium mesh, or customized patient-specific implants, and some surgeons advocate performing no reconstruction at all. Each of these methods has potential limitations related to technical challenges, interference with postoperative imaging, cosmetic deformities, and cost. We sought to develop a technique for orbital reconstruction that is technically straightforward and cost-effective, with an excellent functional and cosmetic outcome.
