神经内窥镜辅助显微手术切除颅内肿瘤

目的探讨神经内窥镜在辅助颅内肿瘤显微手术中的临床应用价值。方法通过近3年来对颅内听神经瘤、胆脂瘤、大囊小结节型血管网织细胞瘤和较大的脑室内室管膜瘤等15例患者,进行内窥镜辅助显微手术。结果7例听神经瘤患者肿瘤(包括内听道内)全部切除,保存了原有内听道结构,面神经颅内段解剖保留5例(5/7),而内听道段全部保留(7/7)。3例胆脂瘤患者中,2例全切除,1例次全切除。3例大囊小结节型血管网织细胞瘤共6个肿瘤结节,全部切除。2例室管膜瘤中有1例镜下全切除,另1例次全切除。所有15例患者中有13例获得6月至2年随访,疗效满意。结论某些显微镜下视野无法到达的肿瘤病灶部分,在内窥镜辅助下得以安全切除成为可能。

Treatment of intracranial tumor with endoscope-assisted microneurosurgery

Objective To investigate the value of the treatment for intracranial tumor with endoscope assisted microneu-rosurgey.Methods 15 patients with intracranial tumors including acoustic neuromas,epidermoid cists,angioreticulomas and ependymomas were treated by endoscope-assisted microneurosurgey in recent 3 years. Rusults 7 cases with acoustic neuromas underwent total resection, and the enlarged internal auditory canal was not be destroyed after operation. The facial nerves within internal auditory canal were preserved (7/7) ,and which located in the intracranial part acquired preservation (5/7) in 5 cases. 2 cases with epidermoid cists underwent total resection (2/3) and 1 subtotal resection (1/3). 3 cases with angioreticulomas including 6 nodes underwent total resection.1 case with ependymoma acquired total resection(1/2), another acquired subtotal resection(1/2) .With the follow-up from 6 to 24 months on 13 patients,the results was well. Conclusion Using the endoscope, it is possible to resect the tumor that can not be observed under the microscope.
