Neurosurgeons should know the anatomy required for safe temporal lobe surgery approaches. The present study aimed to determine the angles and distances necessary to reach the temporal stem and temporal horn in surgical approaches for safe temporal lobe surgery by using a 3.0 T magnetic resonance imaging technique in post-mortem human brain hemispheres fixed by the Klingler method. In our study, 10 post-mortem human brain hemisphere specimens were fixed according to the Klingler method. Magnetic resonance images were obtained using a 3.0 T magnetic resonance imaging scanner after fixation. Surgical measurements were conducted for the temporal stem and temporal horn by magnetic resonance imaging, and dissection was then performed under a surgical microscope for the temporal stem. Each stage of dissection was achieved in high-quality three-dimensional images. The angles and distances to reach the temporal stem and temporal horn were measured in transcortical T1, trans-sulcal T1–2, transcortical T2, trans-sulcal T2–3, transcortical T3, and subtemporal trans–collateral sulcus approaches. The safe maximum posterior entry point for anterior temporal lobectomy was measured as 47.16 ± 5.00 mm. Major white-matter fibers in this region and their relations with each other are shown. The distances to the temporal stem and temporal horn, which are important in temporal lobe surgical interventions, were measured radiologically, and safe borders were determined. Surgical strategy and preoperative planning should consider the relationship of the lesion and white-matter pathways.

神经外科医生应该了解安全颞叶手术方法所需的解剖结构。本研究旨在通过在由 Klingler 方法固定的死后人脑半球中使用 3.0 T 磁共振成像技术，确定在安全颞叶手术的手术方法中到达颞干和颞角所需的角度和距离。在我们的研究中，根据 Klingler 方法固定了 10 个死后人脑半球标本。磁共振图像是在固定后使用 3.0 T 磁共振成像扫描仪获得的。通过磁共振成像对颞柄和颞角进行手术测量，然后在手术显微镜下对颞柄进行解剖。解剖的每个阶段都是在高质量的 3D 图像中实现的。到达颞干和颞角的角度和距离在经皮层 T1、经皮层 T1-2、经皮层 T2、经皮层 T2-3、经皮层 T3 和颞下经侧脑沟入路中测量。前颞叶切除术的安全最大后入点测量为 47.16 ± 5.00 毫米。图中显示了该区域的主要白质纤维及其相互关系。在颞叶手术干预中很重要的颞干和颞角的距离是通过放射学测量的，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。到达颞干和颞角的角度和距离在经皮层 T1、经皮层 T1-2、经皮层 T2、经皮层 T2-3、经皮层 T3 和颞下经侧脑沟入路中测量。前颞叶切除术的安全最大后入点测量为 47.16 ± 5.00 毫米。图中显示了该区域的主要白质纤维及其相互关系。在颞叶手术干预中很重要的颞干和颞角的距离是通过放射学测量的，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。在经皮层 T1、经皮层 T1-2、经皮层 T2、经皮层 T2-3、经皮层 T3 和颞下经侧副沟入路中测量到达颞干和颞角的角度和距离。前颞叶切除术的安全最大后入点测量为 47.16 ± 5.00 毫米。图中显示了该区域的主要白质纤维及其相互关系。在颞叶手术干预中很重要的颞干和颞角的距离是通过放射学测量的，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。和颞下跨侧副沟入路。前颞叶切除术的安全最大后入点测量为 47.16 ± 5.00 毫米。图中显示了该区域的主要白质纤维及其相互关系。在颞叶手术干预中很重要的颞干和颞角的距离是通过放射学测量的，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。和颞下跨侧副沟入路。前颞叶切除术的安全最大后入点测量为 47.16 ± 5.00 毫米。图中显示了该区域的主要白质纤维及其相互关系。在颞叶手术干预中很重要的颞干和颞角的距离是通过放射学测量的，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。这在颞叶手术干预中很重要，通过放射学测量，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。这在颞叶手术干预中很重要，通过放射学测量，并确定了安全边界。手术策略和术前计划应考虑病变与白质通路的关系。
