The aim of this experimental study was to evaluate the feasibility of using fresh cadaveric cow brain as in a training model for microsurgical dissection of sulcus, cisterns, and fissure.
Experimental microneurosurgical activities in this study were performed under the operating microscope. Bilateral sylvian cisterns, interhemispheric fissure, and hemispheric sulcus of the fresh cadaveric cow brain were used as an interested area for this experimental study. The dissection was continued reaching down to the floor of the cistern and total dissection of the middle cerebral artery inside the cisternal space. The suitability of a cow brain as a training model for sylvian fissure microdissection was evaluated as three groups; bad, good, and perfect.
Ten uncovered fresh cadaveric cow brains were used in this experimental feasibility study. The suitability of the experiment for training model was evaluated as bad in (1) 10% of the fresh cadaveric cow brains. The suitability was found as good in (6) 60% of the procedures. In the remaining (3) 30% of the brain dissection, the suitability of the experiment was evaluated as perfect.
In conclusion, performing the sulcal, cisternal, and fissural dissection and protecting the neural and vascular tissue from the mechanical bruising effect of metallic microsurgical instruments are feasible as shown in this study. We believe that this training model will contribute to the practical micro-neurosurgery. Additionally, it provides adequate performance for the microsurgical intervention.
本实验研究的目的是评估使用新鲜牛尸体脑作为脑沟、脑池和脑裂显微手术解剖训练模型的可行性。
本研究中的实验性显微神经外科操作在手术显微镜下进行。新鲜牛尸体脑的双侧外侧裂池、大脑纵裂和脑沟作为本实验研究的感兴趣区域。解剖持续进行，直至到达脑池底部并完全解剖脑池内的大脑中动脉。将牛脑作为外侧裂显微解剖训练模型的适用性分为三组进行评估：差、良和优。
本实验可行性研究使用了10个未覆盖的新鲜牛尸体脑。实验作为训练模型的适用性在10%的新鲜牛尸体脑中被评估为差。在60%的操作中适用性被评为良。在其余30%的脑解剖中实验的适用性被评估为优。
总之，如本研究所示，进行脑沟、脑池和脑裂解剖并保护神经和血管组织免受金属显微手术器械机械性挫伤影响是可行的。我们相信这个训练模型将有助于实际的显微神经外科手术。此外，它为显微手术干预提供了足够的操作性表现。
