Two-Stage Approach for Olfactory Groove Meningioma: Case Illustration
Abstract
A 51-year-old woman presented with an olfactory groove meningioma causing seizures, confusion, and anosmia. Due to the tumor’s large size and frontal lobe edema, a single-stage craniotomy risked brain injury from intraoperative retraction. Complete resection via endoscopic endonasal approach (EEA) alone was not feasible due to the tumor's lateral extent. A two-stage resection was performed, starting with an EEA for decompression and devascularization, followed by a fronto-temporo-parietal craniotomy 4.5 months later, minimizing retraction-related morbidity.
