Unilateral Tailored Fronto-orbital Approach for Giant Olfactory Groove Meningiomas: Technical Nuances

Abstract

Objective: Giant olfactory groove meningiomas (maximum diameter ‡6 cm) remain a surgical challenge. Historically, extensive anterior and antero-lateral ap-proaches have been the primary approaches for removal of such large tumors with limitations and morbidity pertaining to each approach. Herein, the authors describe a minimally invasive, unilateral, tailored fronto-orbital approach for resection of these complex lesions with an emphasis on preservation of the anterior cerebral arteries and olfactory nerves.
