Objective Dorello's canal was first described by Gruber in 1859, and later by Dorello. Vail also described the anatomy of Dorello's canal. In the preceding century, Dorello's canal was clinically important, in understanding sixth nerve palsy and nowadays it is mostly important for skull base surgery. The understanding of the three dimensional anatomy, of this canal is very difficult to understand, and there is no simple explanation for its anatomy and its relationship with adjacent structures. We present a simple, Lego-like, presentation of Dorello's canal, in a stepwise manner. Materials and Methods Dorello's canal was dissected in five formalin-fixed cadaver specimens (10 sides). The craniotomy was performed, while preserving the neural and vascular structures associated with the canal. A 3D model was created, to explain the canal's anatomy. Results Using the petrous pyramid, the sixth nerve, the cavernous sinus, the trigeminal ganglion, the petorclival ligament and the posterior clinoid, the three-dimensional structure of Dorello's canal was defined. This simple representation aids in understanding the three dimensional relationship of Dorello's canal to its neighboring structures. Conclusion Dorello's canal with its three dimensional structure and relationship to its neighboring anatomical structures could be reconstructed using a few anatomical building blocks. This method simplifies the understanding of this complex anatomical structure, and could be used for teaching purposes for aspiring neurosurgeons, and anatomy students.
多雷洛管最早由格鲁伯于1859年描述，后由多雷洛进行了描述。韦尔也描述了多雷洛管的解剖结构。在上个世纪，多雷洛管在理解第六神经麻痹方面具有临床重要性，而如今它在颅底手术中最为重要。对该管三维解剖结构的理解非常困难，且对于其解剖结构及其与相邻结构的关系没有简单的解释。我们以逐步的方式呈现一种简单的、类似乐高积木的多雷洛管展示。材料与方法：在5个福尔马林固定的尸体标本（10侧）上解剖多雷洛管。进行开颅手术，同时保留与该管相关的神经和血管结构。创建一个三维模型来解释该管的解剖结构。结果：利用岩骨、第六神经、海绵窦、三叉神经节、岩斜韧带和后床突，确定了多雷洛管的三维结构。这种简单的呈现方式有助于理解多雷洛管与其相邻结构的三维关系。结论：多雷洛管及其三维结构以及与相邻解剖结构的关系可以用一些解剖学构建块进行重建。这种方法简化了对这种复杂解剖结构的理解，可用于有志成为神经外科医生的人员和解剖学学生的教学目的。
