概括

垂直计算机断层扫描 (CT) 显示,在内镜内骨基手术 (EESBS) 后,重建的骨基 (RSB) 在内移动. 这种转变与脑脊液 (CSF) 泄漏有关,需要量身定制的重建和姿势管理.

科学领域:

神经外科神经外科
放射学放射学是一门学科.
头骨底部手术头骨底部手术

背景情况:

大脑脊髓液 (CSF) 泄漏是内镜内皮骨基手术 (EESBS) 后的常见并发症.
手术后的姿势变化被怀疑会导致CSF泄漏,但缺乏直接证据.

研究的目的:

通过使用直立计算机断层扫描 (CT) 来研究姿势变化对重建的头骨底部 (RSB) 的影响.
为了确定RSB形态变化和手术后脑脊液 (CSF) 泄漏之间的关系.

主要方法:

对30名接受EESBS的患者进行前性研究.
对立式和卧式CT扫描进行比较,以测量RSB形态变化.
形态变化与临床数据和手术因素的相关性.

主要成果:

在RSB中,直立位置的平均内移动为0.94毫米.
影响转移的因素包括病变扩展到状鼻,持续缺陷,手术内脉动和大骨窗.
观察到的转移方向与重力相反,原因是内压力降低.

结论:

直立姿势诱导RSB转移,可能通过重建材料的位移导致CSF泄漏.
骨基重建技术和术后姿势管理应考虑这些形态变化,以防止CSF泄漏.

关键词:

在CSF的泄漏.内镜内外科头骨基底手术.姿势变化姿势变化重建了头骨底部的重建.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
