The further surgical experiences in intracranial meningiomas at Songklanagarind Hospital.

Meningioma is a common benign intracranial tumor documented in many reports. We retrospectively reviewed 81 patients with a total of 84 meningiomas. There were 61 females and 20 males. Most patients were in the third to sixth decades of life. The most common presenting symptoms were headache and decreased visual acuity. Focal neurological deficits and signs of increased intracranial pressure were found in most patients. The three most common tumor locations were falx and parasagittal, sphenoid wing and convexity. Of the 84 meningiomas, 67 were completely resected and 17 were partially resected. Operative morbidities were accounted for by hemiparesis, cranial nerve palsy and infection. There was only one operative death in our series. 70 patients had normal and good results, 4 patients had severe disabilities and results were unknown in 6 patients. Recurrences were detected in 8 patients and 5 patients underwent surgery again with good results in 4 patients. Recurrences occurred in 3 patients with total and 5 patients with subtotal resections. The most significant factor for recurrence was the extent of tumor resection.
