Microsurgical treatment of meningiomas in the middle cortex area:analysis of 24 cases

Objective:To improve the curative effect of microsurgery in treatment of patients with meningiomas in the middle cortex areas.Methods:The clinical data of 24 cases of meningiomas in the middle cortex areas which had been confirmed by surgery and pathology were retrospectively analyzed.Results:Simpson grade Ⅰresection was achieved in 11 cases,grade Ⅱ in 12 cases and grade Ⅲ in 1 case.No patients died during the operation.All the cases were followed up for 3 months to 8 years.No cases with Simpson gradeⅠresection recurred,2 cases with Simpson grade Ⅱ resection relapsed and received the second operation,and the one case with Simpson grade Ⅲ resection did not have obvious change in size of the tumor during the follow-up.Conclusions:Microsurgical technique may elevate the total tumor resection rate in treatment of meningiomas in the middle cortex areas,decrease the injury in the important functional area of the brain,reduce complications and improve the patients' life quality.
