ABSTRACT

Objective To study the clinical classification and the corresponding surgical treatment of the bilateral parafalcine meningiomas.Methods Retrospectively analyzed the clinical data of 37 patients with bilateral parafalcine meningiomas from June 2005 to June 2015.The clinical classification was proposed according to the basement of the tumour,the distance between the basement and symmetry of the tumor.Results 19 cases were male, 18 cases were female.The average age was 55.2 years,average duration was 1.8 years.The clinical classificationⅠtypebilateral tumors with the same basement 33 cases(Ⅰ a typebilateral symmetry 8 cases,Ⅰb typebilateral asymmetric 25 cases);Ⅱ typebilateral tumor had different basement 4 cases(Ⅱa typefar apart 2 cases;Ⅱb typeclose apart 2 cases).Surgery results:25 cases of Simpson Ⅰ excision,6 cases of Simpon Ⅱ excision,5 cases of Simpson Ⅲ excision,complete resection rate was 86.5% (32 /37 ).No operative death cases,the postoperative recovery was good,the clinical symptoms reduced or disappeared,an average follow -up of 35.8 months,no recur-rence cases.Conclusion The clinical classification of the bilateral parafalcine meningiomas was proposed according to the basement of the tumour,the distance between the basement and symmetry of the tumor,can guide the operation scheme,improve the surgical curative effect,has a certain clinical significance.
