ABSTRACT
Objective To analyze the effects of minimally invasive tumor resection under microscope on symptoms improvement,Simpson classification and prognosis in patients with sagittal sinus and falx cerebri meningioma.Methods From December 2012 to December 2016,123 patients with parasagittal and falx meningioma in the People 's Hospital of Shanxi Province were randomly divided into two groups according to the digital table.The control group (61 cases) underwent conventional craniotomy,and the study group (62 cases) performed minimally invasive tumor resection.The symptoms improvement,Simpson classification and postoperative recurrence were compared between the two groups.Results The operation time between the two groups had no statistically significant difference (t =1.13,P ＞ 0.05).The intraoperative blood loss in the study group was (119.05 ± 26.94) mL,which was lower than (172.05 ±27.43) mL in the control group (t =10.81,P ＜ 0.01).The postoperative symptoms improvement of movement of limbs (3.22％),epilepsy (4.65 ％),sensory dysfunction (1.61％) in the study group were significantly better than those in the control group (14.75％,31.15％,27.87％) (x2 =5.02,6.34,4.14,all P ＜ 0.05).The Simpson classification of tumor resection rate in the study group was better than that in the control group(x2 =12.23,P ＜0.01).The incidence rates of complications such as epilepsy(0.00％) and intracranial hemorrhage(1.61％),and recurrence rate(0.00％) in the study group were lower than those in the control group(26.23％,27.87％,27.87％)(x2 =4.05,4.14,4.65,all P ＜ 0.05).Conclusion Minimally invasive tumor resection under the microscope can effectively improve clinical symptoms of patients with sagittal sinus and falx cerebri meningioma,which can improve tumor resection rate,effectively reduce the incidence of postoperative complications and recurrence rate.
