Abstract: Objective To investigate the application value of neuroendoscopy combined with microscope in the resection of cerebellopontine angle epidermoid cyst.Methods he clinical data of 15 cases of cerebellopontine angle epidermoid cyst were retrospectively analyzed.The posterior suboccipital sigmoid sinus approach was adopted in all cases,and the lesions were resected by neuroendoscope combined with microscope.Results All of the 15 patients,12 (80.0%) were completely resected.Subtotal resection was performed in 2 cases (13.3%).The majority was resected in 1 case (6.7%).After 2-22 months follow-up,10 patients with clinical symptoms were relieved.One patient developed new abducens nerve palsy within 1 week after surgery,and one patient developed mild facial paralysis,which returned to normal within 6 months after surgery.One patient developed aseptic meningitis postoperation and was cured by external drainage of lumbar cisterna.Conclusion Microscopy and neuroendoscopy are surgical instruments,both of them have their own advantages and disadvantages.For the operation of complex cerebellopontine angle epidermoid cyst,the advantages of both surgical instruments should be utilized to remove the tumor as much as possible while protecting the patient's neurological function and reducing complications.

摘要： 目的 探讨神经内镜联合显微镜在切除桥小脑区胆脂瘤中的应用价值。方法 回顾性分析15例桥小脑区胆脂瘤的临床病例资料,手术均采用枕下乙状窦后入路,术中应用神经内镜联合显微镜切除病灶。结果 本组15例患者,有12例(80.0%)肿瘤全切除;次全切除2例(13.3%);大部分切除1例(6.7%)。术后随访2～22个月,10例术前有临床症状的得到缓解;1例患者术后1周内出现新发外展神经麻痹,1例出现轻度面瘫,术后6个月内均恢复正常。1例患者术后出现无菌性脑膜炎,予以腰大池外引流治愈。结论 显微镜和神经内镜都是手术设备,两者都有各自的优缺点,对于桥小脑区复杂胆脂瘤的手术,要发挥两种手术设备的各自优势,在保护患者神经功能的前提下,最大程度地切除肿瘤,减少并发症。
