Endoscopic transorbital transpalpebral approach for a sphenoid wing meningioma.

Abstract

Sphenoid wing meningiomas are slow-growing tumors arising in a region crossed by crucial neurovascular structures, for which surgery poses significant challenges. In the last decade, several cadaveric and clinical studies have proven the effectiveness of endoscopic transorbital surgery for skull base pathologies in accordance with the principles of minimal invasiveness. The ventral surgical corridor offered by this approach allows the early devascularization of the lesion without brain retraction, temporal muscle mobilization, and limited neurovascular structure manipulation. This 2D operative video describes the removal of a sphenoid wing meningioma using an endoscopic transorbital transpalpebral approach with minimal morbidity and quick recovery.
