Outcome of medial sphenoidal wing meningioma surgery

Abstract

Abstract Background: Sphenoid wing meningiomas among difficult surgery tumours due to involvement of important structures like optic nerve, cavernous sinus or carotid artery. Objective: to evaluate outcome and prognostic factors in patients with medial sphenoid wing meningiomas after microsurgery in a series of 47 patients with medial sphenoid wing meningioma. Method: This paper includes analysis of 47 patients & their data who underwent surgical management for meningiomas involving the medial sphenoid wing in the period between Jan 2008 and February 2016 at Mansoura university hospital. Results: The most of patients were suffering from visual impairment (59.6%), followed by headaches (38.2%). Total tumor resection were achieved in 23 cases, incomplete in 19 cases and partial resection in 5 cases. Visual acuity improved or stable in 57.4% of the patients. Preoperative neurological deficit remains unchanged postoperative in 35 cases while improved in 4 cases. 8 cases developed permanent 3rd Nerve palsy. Tumor recurrence was in 7 patients. Conclusion: There are many factors influence the prognosis of inner sphenoid wing meningioma including the extent of surgical resection, cavernous sinus invasion, present or absent of peritumoral edema, vascularity of the tumor, size of the tumor, presence or absence of arachnoid plane between the tumor and surrounding neurovascular structures and preoperative neurological condition
