Surgical Management of Sphenoid Wing Meningiomas

Abstract

phenoid ridge meningiomas constitute about 11.9% of all intracranial meningiomas. In 1938, they were classified by Cushing and Eisenhardt into outer (pterional), middle (alar), and inner (deep, clinoidal) lesions. Despite technical advances in neuroimaging and microsurgical techniques, large meningiomas arising from the sphenoid wing still a surgical challenge. Review of the literature concerning sphenoid wing meningioma was presented including; introduction, anatomy, pathology and clinical presentations, imaging features, and treatment options. Between May 2015 and October 2019, 40 patients with meningiomas primarily originating from sphenoid ridge were plannd for surgical management either with total excision or subtotal +GKS or for GKS from the start, 9 cases were lateral, 11 were meddle,14 were medial and 6 enplaque and we can summarize that in lateral and middle meningiomma total excision is the main role in treatment as long as vascular structures are secured, while GKS playing essential role in medial group,small conviened lesions less than 3 cmm in maximum diameter could be treated directly with
