Dorello's canal is an arched structure of bone-fibrous character located in the petroclival venous confluence atop the petrosal bone in the petroclival region. It is bordered by the petrosphenoidal ligament, the petrous part of the temporal bone and the lateral border of the upper part of clivus. Its content in the vast majority of variants comprises the abducens nerve, the inferior petrosal sinus, the venous drainage and the dorsal meningeal artery or its medial branch. With the development of microsurgical techniques, this area has gained huge clinical importance, mainly concerning the order in which the above-mentioned elements (especially the position of the abducens nerve) are arranged in relation to each other. These structures appear in different variant forms and necessitate an individual clinical approach. The main purpose of this review is to present condensed information about possible intercorrelations among them and to indicate, on the basis of the available literature and research, possible surgical approaches and the need to consider the variability when treatments in this region are planned.
Dorello 管是一个拱形的骨纤维结构，位于岩斜坡静脉汇流处的岩骨顶部，在岩斜坡区。它由岩蝶骨韧带、颞骨岩部和斜坡上部外侧缘构成。在绝大多数变异中，其内容物包括展神经、下岩窦、静脉引流和硬脑膜动脉或其内侧支。随着显微外科技术的发展，该区域具有巨大的临床重要性，主要涉及上述元素（特别是展神经的位置）相互之间的排列顺序。这些结构以不同的变异形式出现，需要采取个体化的临床方法。本文的主要目的是介绍它们之间可能存在的相互关系的简明信息，并根据现有文献和研究结果，指出在该区域进行治疗时可能的手术入路和考虑变异性的必要性。
