目的探讨采用枕下乙状窦后-内听道上结节入路切除岩斜区脑膜瘤的安全性、有效性,以及优缺点。方法回顾性分析自2002年1月至2004年12月采用枕下乙状窦后-内听道上结节入路切除的岩斜区脑膜瘤11例。所有肿瘤主体均位于后颅窝,侵袭海绵窦和/或Meckel’s腔,其中6例伴有脑干受压移位,3例有岩尖骨性改变,5例肿瘤部分或全部包绕椎基底动脉及其主要分支。结果肿瘤全切除8例,次全切除3例。术前有听力者9例,其中1例因肿瘤巨大,术后听力丧失。出院后随访,7例、3例和1例面神经功能分别恢复至1级、2级和3级。所有患者术后恢复满意,无死亡和严重并发症发生。结论枕下乙状窦后-内听道上结节入路是一种安全有用的乙状窦后改良入路,适合于主体在后颅窝,并向中颅窝、Meckel’s腔扩展的岩斜区大型肿瘤的手术切除。
Objective To investigate the safety, efficacy, advantages and disadvantages of using suboccipital sigmoid sinus posterior-internal tibial nodal approach to remove petroclival meningioma. Methods From January 2002 to December 2004, 11 cases of petroclival meningioma were retrospectively analyzed by posterior suboccipital sigmoid sinus surgery. All tumor bodies were located in the posterior fossa, cavernous sinus and / or Meckel’s cavity, including 6 cases with brainstem pressure shift, 3 cases of petrous apex change, 5 cases of tumor partially or completely encircled vertebrobasilar artery And its main branch. Results Tumor resection in 8 cases, subtotal resection in 3 cases. There are 9 cases of preoperative hearing, including 1 case of huge tumor, postoperative hearing loss. Follow-up after discharge from the hospital, 7 cases, 3 cases and 1 case of facial nerve function were restored to level 1, level 2 and level 3 respectively. All patients recovered satisfactory, no deaths and serious complications occurred. Conclusion Posterior subrethrocystic sinus posterior - intranasal nodal approach is a safe and useful sigmoid sinus retrospective approach, suitable for the main body in the posterior fossa, and to the middle cranial fossa, Meckel’s cavity expansion of the rock slope Surgical resection of large tumors.
