Aim:Surgical removal of spinal meningiomas are usually not difficult . In neurosurgical practice, their locations and growing paterns may be affect surgical results. Ventrally located and en plaque meningiomas may not be removed totally. The aim of this study was to present the results of surgery in cases with spinal meningiomas, and reveal the factors affecting outcome.Material and Methods:There were 46 cases operated between January 1995 and December 2009 in single clinic. There were 33 female and 13 male patients. The mean age was 52. All patients underwent microsurgical resection using posterior approach.Results:Total resection was obtained in 38 patients (82%). Twenty-eight (61%) patients experienced clinical improvement after surgery. Tumor was completely dorsal to the spinal cord in 30 cases, dorsolateral in nine and ventral to the spinal cord in seven cases. We experienced eight recurrences (17%).The recurrence were seen most commonly in ventrally located tumors (62%). Conclusion:Complete resection of spinal meningiomas seem to produce a good clinical outcome. Recently, advances in microneurosurgery and neuroimaging techniques have resulted in decreases in morbidity and recurrence rates in spinal meningiomas.
