Abstract：
Background Transsylvian approach is one of the main approaches for a variety of vascular, tumor, and skull-base lesions. Sylvian fissure harbors a lot of critical structures including the middle cerebral artery and many venous structures. If not done properly, the transsylvian approach could cause several complications. Up to now, there is no simple training model for practicing Sylvian fissure dissection. In this article, we describe the technique of using microscissors for the sharp dissection of arachnoid trabeculae. We also propose a new model for practicing Sylvian arachnoid dissection using a three-dimensional (3D) brain model with cotton fiber. Materials and Method We inserted cotton fiber into the Sylvian fissure of the brain model (aneurysm box from UpsurgeOn) and covered the Sylvian fissure with a cotton sheet, then sprayed the water over it. We dissected this model under a microscope by using Kamiyama scissors in the right hand and suction in the left hand. Result Under the microscope, our model appears comparable with the real Sylvian fissure. We can use this model for practicing arachnoid dissection with Kamiyama scissors. Conclusion The arachnoid dissection model by using a 3D brain model with cotton fiber is a simplified and novel approach for practicing the Sylvian fissure dissection.
摘要：
背景跨侧裂法是治疗多种血管的主要方法之一,肿瘤，和颅底病变.Sylvian裂有许多关键结构，包括大脑中动脉和许多静脉结构。如果做得不好，跨侧突入法可能会导致多种并发症。到目前为止,没有简单的训练模型来进行Sylvian裂隙解剖。在这篇文章中,我们描述了使用微剪刀尖锐解剖蛛网膜小梁的技术。我们还提出了一种使用带有棉纤维的三维（3D）脑模型进行Sylvian蛛网膜解剖的新模型。材料与方法我们将棉纤维插入大脑模型的Sylvian裂隙（来自Upsurgeon的动脉瘤盒）中，并用棉片覆盖Sylvian裂隙，然后把水喷在上面。我们在显微镜下使用右手的神山剪刀和左手的吸力解剖了这个模型。结果在显微镜下,我们的模型看起来与真实的Sylvian裂缝相当.我们可以用这个模型用神山剪刀进行蛛网膜解剖。结论利用带有棉纤维的三维脑模型建立蛛网膜夹层模型是一种简化和新颖的方法。
