目的：探索经乙状窦后入路神经内镜辅助显微手术治疗桥小脑角肿瘤的应用价值。方法对21例桥小脑角肿瘤采取乙状窦后入路神经内镜辅助显微手术治疗，在显微镜下切除肿瘤后，再用神经内镜进行探查，切除残余肿瘤。结果12例听神经瘤11例全切并保留面神经，1例因与周围血管、神经粘连紧密，行次全切除；8例胆脂瘤及1例脑膜瘤全切除，无术后并发症及死亡。结论经乙状窦后入路神经内镜辅助显微手术治疗桥小脑角肿瘤，有助于提高肿瘤全切率，可提高手术疗效，降低手术危险性。

Objective :To discuss the value of the nueroendoscope- assisted microsurgery for cerebellopontine angle tumours by retrosigmoid approach. Methods A retrosigmoid craniotomy and nueroendoscopic assisted microsurgical tumour resection was performed on 21 patients with cerebellopontine angle tumours. Resected the turmor with microneurosurgery, then under nuroendoscopy remain of turmors was found out and removed. Result 11 of 12 acoustic nueromas were resected completely with preservation of facial nerves.1 of 12 acoustic nueromas was subtotally removed. Total resection of tumours was carried out respectively in eight cholesterotomas and one meningioma. No aseptic meningitis, delayed intracranical hemorrhage and other complications occurred. Conclusion The nueroendoscope-assisted microsurgery for cerebellopontine angle tumours by retrosigmoid approach can increase the total resection rate for tumors, which is helpful to improve the microsurgical treatment effect and lessen the operative risk.
