后颅窝脑肿瘤手术中颅神经电生理监护的作用

目的：研究在后颅窝肿瘤切除术中运用术中神经电生理监护颅神经功能。方法：选取本院2008年1月～2009年6月后颅窝脑肿瘤患者23例,所有患者在肿瘤切除过程中均监护第Ⅴ、Ⅶ、Ⅸ、Ⅻ对颅神经,分析效果。结果：肿瘤全切17例,肿瘤近全切3例,肿瘤部分切除3例。术后3个月House-Brackmann面瘫Ⅴ级患者2例,Ⅲ～Ⅳ级3例,Ⅰ～Ⅱ级18例;吞咽功能减退2例。结论：后颅窝脑肿瘤手术中监护第Ⅴ、Ⅶ、Ⅸ、Ⅻ对颅神经肌电图能保护患者相应的颅神经功能。

Monitoring cranial nerves in patients with posterior fossa tumor resected

Objective：To study intraoperative cranial nerves monitoring in patients with posteiror fossa tumors resected. Methods：From January 2008 to June 2009,23 cases with posterior fossa tumor were followed up with facial muscle function after the tumor was resected with intraoperative cranial nerves monitoring.Results：The tumors in 17 cases were totally resected,3 cases subtotally resected,and 3 cases partially resected.At postoperative three months,there were 2 patients with House-Brackmann facial nerve Grade Ⅴ,3 patients with grade Ⅳ to Ⅲ,18 patients with Ⅱ to Ⅰ.Conclusion：Intraoperative monitoring cranial nerves with Ⅴ,Ⅶ,Ⅸ,Ⅻ could protect cranial nerves function during posterior fossa tumor being resected.
