Value of Surgery on the Outcome of Olfactory Groove Meningioma

Background: Olfactory groove meningiomas represent a difficult problem because of involvement of the arteries of the anterior circulation as well as the anterior visual pathways when increased in size. Objective: in my study I will discuss 12 patients with olfactory groove meningiomas regarding their clinical presentation, radiological appearance, surgical approach as well as their post operative follow-up. Methods: All patients had been operated in Al-Azhar university hospitals in the period between February 2005 to October 2011. Patients' data as clinical presentation, surgical approach, histopathology, outcomes and follow up were collected and recorded. Results: There were 10 women and two men ranging in age from 33 to 64 years with mean age of 47 years. The leading symptom was Dementia in 5 patients. The bifrontal approach was the surgical approach in all cases. Simpson grade I or II was achieved in 9 patients, and grade III or IV was attained in 3 cases. In 11 patients there was a good result. One patient had a postoperative intracerebral hemorrhage after surgery and has a permanent dysphasia. Conclusion: The Olfactory groove meningiomas are frequent tumor in neurosurgical practice that should be excised completely with minimum complication and good outcome. [Abdel-Basset Ali Saleh.
