Important role of endoscope in tuberculum sellae meningioma resection via supraorbital keyhole approach.

Abstract

Tuberculum sellae meningiomas pose a surgical challenge due to the tumor adhesion to vital structures. In many cases, tumor residue and dural tail sign may contribute to an opportunity for future recurrence. In this study, we introduced endoscopic technique in supraorbital keyhole approach to further resected residual tumor and dural attachments that are traditionally difficult to detect under microscopic surgery, and finally achieved Simpson Grade II resection. The use of endoscopy offers enhanced visualization and ensures more reliable Simpson Grade II resection outcomes for tuberculum sellae meningiomas.
