Because the lateral ventricles of cadaver heads are often collapsed, they can be difficult to cannulate endoscopically. We present a novel method for preparing a cadaveric model for endoscopic intraventricular procedures.
A burr hole was placed in the midpupillary line anterior to the coronal suture. A triangular wedge of frontal scalp, skull, and dura with its base 6 cm superior to the orbitomeatal line and 6 cm posterior to the forehead was cut and removed. A wedge of the underlying brain was similarly cut along the edge of the bone window. After removal of the brain block, the anterior horn of the lateral ventricle was exposed. The endoscope sheath was inserted through the burr hole into the anterior horn in the brain block, following its return to its original location with the skull and scalp.
This model is easily prepared and optimizes training in endoscopic ventricular surgery.
由于尸体头部的侧脑室常常塌陷，在内镜下进行插管可能会很困难。我们提出一种用于准备内镜下脑室内手术尸体模型的新方法。
在冠状缝前方的中瞳孔线上开一个骨孔。切下一块三角形的额部头皮、颅骨和硬脑膜楔形块，其底部位于眶耳线上方6厘米且前额后方6厘米处，然后将其移除。沿着骨窗边缘类似地切下一块下方的脑楔形块。移除脑块后，暴露侧脑室的前角。将内镜鞘管通过骨孔插入脑块中的前角，随后将其与颅骨和头皮一起恢复到原来的位置。
该模型易于制备，可优化内镜下脑室手术的训练。
