An endoscopic endonasal technique for resection of olfactory groove meningioma

Abstract

Meningiomas of the olfactory groove have generated a significant amount of discussion in the literature regarding preferred surgical approach. Neuropsychiatric dysfunction is one of the most common presenting symptoms, so surgical approaches have focused on the need to minimize further dysfunction, chiefly by reducing retraction on the frontal lobes. We report a case of olfactory groove meningioma treated with a minimally invasive entirely endoscopic technique. The endoscopic endonasal technique represents a possible alternative for suitably selected cases and could be expected to minimize neuropsychiatric sequelae.
