The aim of this study is to investigate the sulcal and the gyral anatomy of the orbitofrontal cortex with its arterial supply. Ten gross formaline fixed adult brains (20 hemispheres) were used to show the gyral and sulcal anatomy of the inferior frontal lobe, and its arterial supply. The arteries were investigated with special attention to the relationship between the recurrent artery of Heubner (RAH) and the gyrus rectus (GR). Medial and lateral orbital sulci were connected in 4 right hemispheres, and in 7 of the left. The orbital sulci were connected with olfactory sulcus in one right hemispheres, but not in the left. In the right hemispheres, the RAH traveled across the GR in 7 hemispheres and looped over the posterior aspect of the GR in 3 hemispheres. In the left hemispheres, RAH crossed the GR in 8 and looped over the posterior aspect of the GR before entering the anterior perforating substance in 2 hemispheres. There are considerable variations among the gyri and sulci of the orbitofrontal cortex and it is difficult to describe a precise architectural pattern. The RAH demands special attention during GR resection in aneurysm surgery.
本研究的目的是研究眶额皮质的脑沟和脑回解剖结构及其动脉供应。使用10个经甲醛固定的成年大脑标本（20个半球）来展示额下叶的脑回和脑沟解剖结构及其动脉供应。对动脉进行了研究，特别关注了赫布纳返动脉（RAH）与直回（GR）之间的关系。在4个右半球和7个左半球中，内侧眶沟和外侧眶沟相连。在1个右半球中，眶沟与嗅沟相连，而在左半球中则未发现这种情况。在右半球中，RAH在7个半球中穿过GR，在3个半球中绕过GR的后部。在左半球中，RAH在8个半球中穿过GR，在2个半球中在进入前穿质之前绕过GR的后部。眶额皮质脑回和脑沟之间存在相当大的变异，难以描述精确的结构模式。在动脉瘤手术中切除GR时，RAH需要特别关注。
