Microsurgical resection of large cerebellopontine angle tumor

Objective To discuss the clinical effectiveness and complications of microsurgical resection of cerebellopontine angle tumor. Methods We applied microsurgical operations to 22 largc cerebellopontine angle tumors (include 11 acoustic neurinomas ,8 meningiomas ,2 trigeminal tumors and 1 cholesteatoma)and analyzed t0he clinical results. Results 8 cases received total resection and 3 cases received subtotal resection within the 11 acoustic neurinomas. 5 cases received total resection,2 cases received subtotal resection and 1 case received partial resection within the 8 meningiomas. Both of the 2 trigeminal tumors received subtotal resection.1 cerebral hemorrhage dead after re-operation. Conclusion Microsurgical operation of large cerebellopontine angle tumor is challenging. Professional microsurgical techniques can improve total resection ratio and reduce the incidence of complications. Key words: Microsurgery;  Cerebellopontine angle;  Acoustic neurinoma;  Meningioma
