目的 探讨三叉神经鞘瘤的临床表现、神经影像学改变和手术方式及影响肿瘤全切除的因素。 方法 5 1例患者根据肿瘤生长部位不同而采取了不同的手术入路 :(1)单纯颅中窝者 ,采用扩大中颅窝或扩大翼点入路 ;(2 )骑跨中后颅窝者 ,采用乙状窦前入路 ;(3)单纯颅后窝者 ,采用枕下入路。 结果 肿瘤手术全切除率为 80 0 % ,术后完全恢复正常者为 75 0 % ,仅 2例患者术后 2年有肿瘤复发。 结论 新的手术方式提高了肿瘤的全切除率 ,特别是对于指导临床手术入路及肿瘤的全切除具有实用价值。
Objective To investigate the clinical manifestations, neuroimaging changes and surgical procedures of trigeminal schwannoma and the factors influencing total tumor excision. Method 5 One patient underwent different surgical approaches depending on the site of tumor growth: (1) a simple cranial fossa with enlarged midcranial fossa or enlarged pterional approach; (2) , The sigmoid anterior approach; (3) simple posterior fossa, the use of suboccipital approach. Results The total tumor resection rate was 80 0%, and the rate of complete recanalization was 75 0%. Only 2 patients had tumor recurrence 2 years after operation. Conclusion The new surgical approach improves the total resection rate of the tumor, especially for guiding clinical surgical approach and total resection of the tumor.
