Microsurgical Treatment Of Tentorial Meningiomas-retrospective Analysis Of20Cases

ObjectiveSummarizes the optimal surgical approach of the different typies of tentorialmeningioma and the operation skills of tentorium meningioma resection.MethodAnalytical the clinical data of the patients with tentorial meningioma in ourhospital during2007-1to2013-6, explore different typies of tumor, choose the bestsurgical approach and the best method of surgical removal of the tumor.Results20cases of tentorial meningiomas，according to the classification method ofWang Zhongcheng, the tumor is located on the tentorium in10cases(50%),6cases(30%) under tentorium across the screen that dumbbell-shaped4cases(20%).Using temporal occipital approach3cases (15%), the use of the road into the nextscreen on the cerebellum3cases (15%), using the suboccipital approach3cases(15%), next to the right side of the midline approach using2cases (10%), after usingthe middle road into2cases (10%), the use of temporal approach2cases (10%), theuse of inter-hemispheric suboccipital approach2cases (10%), using the tentoriumdown into2cases combined road (10%), the use of expanded pterional1case(5%).10received Simpson Grade I resection of the tumors，5Grade II，2Grade Ⅲ,3gradeⅣ．Postoperative complications occurred in6cases (30%).The quality of life was significantly improved, patients were followed up for6months to6years,2ofthem.the tumor volume has been increase,1of whom underwent surgery again.CondusionsThe location of the tentorial meningioma is deep,And the tissueis of thesurrounding are important,So the surgical resection of it is difficult.Precise surgicalapproach is conducive to the full removal of the tumor and reduce postoperativecomplications and improve quality of life for patients.
