Background: Meningiomas account for approximately 15 percent of primary cranial tumor and the most common tumors of the sphenoid wing region in the anterior cranial fossa base [1]. A thorough knowledge of the anatomy of the region and adherence to basic microneurosurgical principles can help achieve outstanding surgical results. We present our experience in surgical management of these cases for a total of 23 cases and a mean follow up of 18 months at a single centre. Methods: This prospective observational study was conducted from August 2013 to December 2016 in the department of Neurosurgery in our centre which is a tertiary care hospital in western India. All patients were operated using standard microneurosurgical techniques. Results: The average age of the patients was 43.13±11 years. Middlelateral location was the most common presentation (43.47%) followed by lateral location (30.43%). Optic canal invasion, cavernous sinus involvement was more in medial tumours as compared to lateral tumours. Gross total resection of the tumour was achieved in 19 of 23 (82.60%) cases. Orbitozygomatic craniotomy was done in 8 (34.78%) cases. Majority (69.56%) of the tumours were found to be gradeII on HPE. No new neurodeficit developed in most cases. Persistent neurodeficits were observed in 5 patients (Diplopia3, seizures1, headaches1). Conclusion: Our results are consistent with the current acceptable standards in treatment lateral sphenoid wing meningioms. However, there is scope for much improvement in dealing with medial sphenoid meningiomas, treatment of which should be planned on case to case basis.
