颈静脉孔分为岩部、神经部和乙状窦部,硬膜返折是辨认孔内颅神经的标志。颈内动脉、椎动脉、面神经、迷路、耳蜗等结构包绕颈静脉孔周围,为该区肿瘤手术带来很大难度。个体化的选择手术入路,利用球内切除、维持肿瘤与正常组织间界面等技巧一期全切肿瘤,并严密缝合硬膜、以带蒂肌瓣填塞死腔,可提高肿瘤控制率,减少颅神经功能障碍及脑脊液漏等并发症的发生。
Jugular vein hole is divided into rock, nerve and sigmoid sinus, dural fold is to identify the cranial nerve within the hole mark. Internal carotid artery, vertebral artery, facial nerve, labyrinth, cochlear structure around the jugular vein around the hole for the operation of the tumor brought great difficulty. Individualized choice of surgical approach, the use of ball resection, maintaining the interface between the tumor and normal tissue techniques such as a total tumor resection, and stricture of the dura mater to fill the dead space with pedicled muscle flap, can improve tumor control rate, reduce Cranial nerve dysfunction and cerebrospinal fluid leakage and other complications.
