颈静脉孔区神经鞘瘤发病率较低。手术切除是过去首选的治疗方法,但肿瘤全切除率极低,且手术后多数病人后组颅神经障碍的症状有所加重或产生面瘫。80年代以前文献报道手术后死亡率在9.1%~16.1%。伽马刀治疗颈静脉孔区神经鞘瘤是十多年来开展的新项目,但临床报道很少。我院对8例病人进行伽马刀治疗,结合随访情况作一总结。 相似文献

颈静脉孔区颅内-外沟通瘤的手术治疗 总被引:1,自引:0,他引:1
目的:总结、探讨远外侧经颈静脉孔入路治疗颈静脉孔区颅内-外沟通瘤的手术方法和注意事项。方法:对17例颈静脉孔区颅内-外沟通瘤患者采用远外侧颈静脉孔入路切除肿瘤。结果:患者肿瘤全切除13例,近全切除3例,次全切除1例。术后患者功能障碍大多明显改善。10例患者获临床和MRI随访3~42个月,未见肿瘤残留和复发。结论:采用远外侧经颈静脉孔入路可以充分暴露颈静脉孔区,利于手术同时切除颅内-外肿瘤。采用从颈静脉孔上、下两端分离肿瘤的手术方法,可保持肿瘤包膜完整,是减少颈静脉(球)和神经损伤、防止肿瘤残留的关键。根据DSA或MRV显示,结合术中判断乙状窦闭塞的情况切开乙状窦。手术结束时须严密缝合硬脑膜。 相似文献

ObjectiveWe present our experience with surgery of jugular foramen schwannomas with special consideration of clinical presentation, surgical technique, complications, and outcomes.MethodsThis retrospective study includes ten patients with jugular foramen schwannomas treated by the senior author between January 2007 and December 2012. Three patients had undergone partial tumour resection elsewhere. The initial symptom for which they sought medical help was hearing loss, dysphagia, hoarseness, and shoulder weakness. Preoperative glossopharyngeal and vagal nerve deficits were the most common signs. In our series, tumour extension was classified according to Kaye-Pellet grading system. In two cases the tumours were classified into type A and 8 patients presented with type D tumours. A retromastoid suboccipital craniotomy was performed for type A tumours and modifications of cranio-cervical approach were suitable for type D.ResultsNo death occurred in this series. Four patients deteriorated after surgery: in two patients preoperative cranial nerve deficits deteriorated after surgery while new cranial nerve palsy occurred in 2 other patients. In four patients, the cranial nerve dysfunction had improved at the last follow-up examination. In all other patients, the cranial nerve dysfunction remained the same. One patient experienced tumour recurrence over a follow-up period of 40 months. This patient underwent a successful second surgery without further evidence of tumour growth.ConclusionsJugular foramen schwannomas can be radically managed with the use of skull base surgery techniques. However, the surgical treatment of jugular foramen schwannomas carries a significant risk of the lower CN deficits. 相似文献

远外侧经髁入路到颈静脉孔区的国人显微解剖 总被引:1,自引:0,他引:1
目的:探讨远外侧经髁入路到颈静脉孔区的显微解剖结构,为颈静脉孔区手术入路提供解剖学基础。方法:对10例经福尔马林固定的成人湿性头颅标本和10例成人头颅骨标本进行解剖学观察,通过模拟该手术入路对颈静脉孔区的重要解剖标志进行描述和测量。结果:颈静脉孔内口距内耳门为4.54±0.88mm;颈静脉孔内口距舌下神经管内口为9.06±1.24mm;舌下神经管内口到枕骨髁后缘的距离是10.08±0.76mm;舌下神经管内口到颈静脉结节的距离是7.22±1.44mm;该手术入路的关键是枕髁的正确磨除和椎动脉的安全显露,并且在手术过程中要注意小脑前下动脉的变异。结论:通过远外侧经髁入路可以较好地从后方暴露颈静脉孔区及其毗邻结构,避免了颞骨岩部的磨除,面神经的移位,减少了神经损伤等不利因素。 相似文献

ObjectWe present our experience with surgery of jugular foramen meningiomas with special consideration of clinical presentation, surgical technique, complications, and outcomes.MethodsThis retrospective study includes three patients with jugular foramen meningiomas treated by the senior author between January 2005 and December 2010. The initial symptom for which they sought medical help was decreased hearing. In all of the patients there had been no other neurological symptoms before surgery. The transcondylar approach with sigmoid sinus ligation at jugular bulb was suitable in each case.ResultsNo death occurred in this series. All of the patients deteriorated after surgery mainly due to the new lower cranial nerves palsy occurred. The lower cranial nerve dysfunction had improved considerably at the last follow-up examination but no patient fully recovered. Two of three patients with preoperatively impaired yet functional hearing deteriorated after surgery with no subsequent cranial nerve VIII function improvement. In one case postoperative stereotactic radiosurgery was performed due to non-radical tumour resection (Simpson Grade IV) and tumour remnant proved stable in the 4-year follow-up. None of the patients have shown signs of tumour recurrence in the mean follow-up period of 56 months.ConclusionsJugular foramen meningiomas represent one of the rarest subgroups of meningiomas and their surgical treatment is associated with significant risk of permanent cranial nerve deficits. 相似文献

BackgroundDumbbell-shaped jugular foramen schwannomas (JFS) are rare but challenging for the treatment. Surgical resection is believed to be the optimal therapy; however, postoperative dysfunction of the lower cranial nerves (CNs), tumor residual, cerebrospinal fluid (CSF) leakage, and subcutaneous hydrops are common. The current study's objectives were to describe the optimal surgical strategies for the total removal of dumbbell-shaped JFS, the functional preservation of lower CNs, and the prevention of postoperative CSF leakage.Methods26 consecutive patients with dumbbell-shaped JFS were surgically treated between January 2014 and June 2019. All patients were operated on via two-piece lateral suboccipital approach, vascularized muscle flap was used for the repair of the dural defect after an operation. The clinical information and radiological data of these patients were retrospectively reviewed, and the optimal surgical strategies were further evaluated and discussed.ResultsThe tumor was completely removed in all 26 patients, one patient developed new CN Ⅶ paralysis, and 2 developed new CN IX and Ⅹ paralysis after an operation, all patients were significantly relieved during follow up. None of them developed subcutaneous hydrops and postoperative CSF leakage. No tumor recurrence was observed during a mean follow up of 38.8 (16–69) months.ConclusionsDumbbell-shaped JFS could be safely and completely removed via the two-piece lateral suboccipital approach. Postoperative CSF leakage could be effectively prevented by careful repair of the dural defect in the jugular foramen (JF) and filling the mastoid cavity with a vascularized muscular flap. 相似文献
