神经内镜辅助显微手术治疗桥小脑角胆脂瘤

Neuroendoscope-assisted microsurgical resection of epidermoid cyst of the cerebellopontine angle

目的探讨神经内镜辅助下的显微手术在治疗桥小脑角胆脂瘤中的临床意义。方法在神经内镜辅助下应用显微神经外科技术治疗桥小脑角胆脂瘤23例。在显微镜视野下最大限度切除肿瘤,再在神经内镜下观察并切除残余肿瘤。结果显微镜下切除肿瘤后,仍有18例通过神经内镜发现肿瘤残留,内镜下进一步彻底切除肿瘤。术后1个月内有18例原有症状消失,2例面瘫和1例复视患者症状减轻,1例术前无症状患者术后1周出现迟发性面瘫,经治疗在术后1个月随访时恢复正常。结论神经内镜辅助显微手术切除桥小脑角胆脂瘤,可以防止肿瘤残留,减少并发症,保护神经功能。

Objective To study the significance of neuroendoscope-assisted microsurgery in the treatment of epidermoid cyst of cerebellopontine angle.Methods A total of 23 patients with epidermoid cyst of cerebellopontine angle were treated by neuroendoscope-assisted microsurgery.Tumor was gross-total resected under the microscope,and the residual tumor was removed by neuroendoscopy.Results After microscopic resection of the tumor,18 cases were still found to have residual tumor through neuroendoscopy,and the tumor was further completely removed under endoscopy.Within a month after the operation,18 cases of original symptoms disappeared,two cases of facial paralysis and one case of diplopia were relieved.One patient presented with delayed facial paralysis in one week after operation,and the patient recovered after a month of follow-up.Conclusions Endoscopic microsurgical resection of epidermoid cyst of cerebellopontine angle can prevent tumor residue,reduce complications and protect nerve function.
