Background:
Meningiomas are primary and the second most common type of benign tumors of
central nervous system derived from meningothelial cells. Objective: To
evaluate the clinical outcome of posterior approach microsurgical resection of
spinal meningiomas. Methods: Thirty-two patients underwent microsurgical
resection via the posterior approach; as well visual analogue scale (VAS) and
medical research council (MRC) were used for clinical evaluation. All patients
underwent clinical evaluation, MRI pre- and post-operation. Follow up duration
was about 1 year after surgery. Results: The patients enrolled 26 females and six
males, with a median age of 48 years old (range 22-74). 26 Cases experienced
clinical improvement following operations. The extent of tumor resection was
Simpson Grade I in 5 patients, Grade II in 20, Grade III in 7. No recurrence
could be detected on one-year follow up. There were two cases of postoperative
CSF leakage and two cases of worsened neurological status due to operative
morbidity. There was no immediate postoperative mortality. Conclusion: Gross
total resection is associated with no recurrence and favorable clinical outcome
when applied, regardless of dural origin control. [Egypt J Neurol Psychiat Neurosurg. 2013; 50(3): 235-240]
