Clinical Research of Microsurgical Removal of Falx Meningiomas

Objective To investigate the strategy and surgical methods for the microsurgical removal of falx meningiomas.Methods The clinical data of patients undergoing the the microsurgical removal of falx meningiomas were collected.The clinical manifestations and KPS scores before and after the treatment were compared.Results According to tumor location: 11 cases were with the meningiomas locating at anterior one-third of the cerebral falx,17 cases at central one-third of the of the cerebral falx,and 7cases at posterior one-third of the of the cerebral falx.According to the size of tumor: 11 cases were with meningiomas more than 6cm in diameter,19 cases within 4 cm to 6 cm,5 cases less than 4 cm.33 patients underwent total tumor resection,2 cases subtotal resection.The postoperative KPS significantly higher than that before the operation in patients with falx meningioma,P 0.05.Conclusion The microsurgical removal can increased the total tumor resection rate of falx meningiomas,decrease the recurrence and death rates.The rational incision,intraoperative stopping bleeding completely,avoiding the injury of cerebral cortex and piecemeal resection are the keys to improve the surgical efficacy and decrease the incidence of postoperative complications.
