Microsurgical removal of sphenoidal ridge meningiomas

Twenty two cases of sphenoidal ridge meningiomas are the subject of this study. There was a female prepondrance [86.3+ACU-] with the greatest incidence in the sixth decade of life and more [60+ACU-]. The major presenting symptom was headache, followed by optic atrophy, proptosis, epilepsy and hemiparesis. The main diagnostic tool was the C.T. Scan and angiographic study was performed in most of the cases for the proper planning of the surgical technique. Frontotemporal craniotomy with outer sphenoidectomy was the commonest approach used with frontal or temporal extension accordingly, using the microneurosurgical technique and aiming at total excision. The complications faced with were cerebrospinal fluid leak, infection, visual deterioration and postoperative hemiplegia due to a major vascular injury. Follow up C.T scans were done to all cases showing complete excision in twelve cases
