简介：AbstractObjective:To describe the procedure and results of an adapted closure and reconstruction technique for translabyrinthine surgery that focuses on identifying and managing potential pathways for CSF egress to the middle ear and Eustachian tube.Methods:Retrospective review of a cohort of translabyrinthine acoustic neuroma cases that were reconstructed using this technique.Results:In addition to meticulous packing of potential conduits using soft tissue, hydroxyapatite cement is used to seal opened air cell tracts prior to obliteration of the mastoid defect using adipose tissue. Early results of a small patient cohort using this technique are encouraging and there were no wound infections. There was a single case of CSF rhinorrhea associated with incomplete sealing of opened petrous apex cells, with no recurrence after appropriate implementation of the described protocol during revision surgery.Conclusion:Proactive management of potential conduits of CSF egress including opened air cell tracts has a high likelihood of reducing rates of rhinorrhea and need for revision surgery after the translabyrinthine approach to the posterior fossa.

简介：客观：在中间的头部的窝底(EHMCFB)探索临床的特征，CT表明和创伤的额外的硬脑膜下血肿的起作用的指示。方法：有到2000年5月的从1997年1月的创伤的EHMCFB的14个盒子的一个总数回顾地被分析。结果：14个盒子，维持的12个盒子(85.7%)形成水塘的禅宗ge为被压的ambiens；11个盒子收到了操作的人，都被治好；3收到了保守治疗，2更好变得，1死了。结论：在创伤的EHMCFB，形式水塘变化ambiens容易发生。因此，如果显得日益增多地加重了，形式在水塘以后水塘换掉ambiensambiens正在被压，一早nd活跃操作必要、关键。

简介：AbstractThis article presents a case of low-grade cribriform cystadenocarcinomas (LGCCC), a rare salivary gland tumor manifesting in the infratemporal fossa (ITF). The lesion in this case is unique in its location, histopathology, and management in that the tumor resection was performed using an exclusively endoscopic, endonasal approach. This case highlights the expanding application of endoscopic skull base techniques to address an indolent, slow-growing malignancy of the ITF.

简介：AbstractBackground:Basilar invagination (BI) with atlantoaxial dislocation (AAD) is not uncommon in patients with scoliosis, Klippel-Feil syndrome (KFS), and other bone deformities. Cases with combinations of the abovementioned dislocations and deformities with posterior cranial fossa teratoma are rare in the clinic and difficult to handle.Case presentation:This case presents a 34-year-old woman diagnosed with atlantoaxial dislocation and posterior cranial fossa mass. After two surgeries, the posterior cranial teratoma was completely removed with satisfactory atlantoaxial reduction. The postoperative 1-year follow-up examination showed that the bone graft fusion was successful, without remaining significant dysfunction.Conclusions:The surgical risk of irreducible atlantoaxial dislocation combined with posterior cranial fossa tumor is huge. Thus, it needs to be fully preoperatively evaluated and managed carefully in accordance with sound surgical principles.
