We studied the surgical anatomy of the anterior clinoid process (ACP) and its adjacent structures in cadaver heads. We paid special attention to the anatomical relationships between the ACP and adjacent structures to determine the surgical landmarks for safe anterior clinoidectomy. Thirty-five cadaver heads were dissected and the ACP regions were examined in 55 skull sides. We observed that in eight sides the ACP had been pneumatized from the sphenoid sinus. The caroticoclinoid foramen was revealed in only eight sides. The extra-ocular nerves ran forward to the superior orbital fissure at the inferolateral aspect of the ACP, with the oculomotor nerve being closest. The posterolateral area of the carotico-oculomotor membrane was thin and incomplete in nine sides. The study clarified the anatomical relationship between the ACP and its surrounding structures, and identified the major variations experienced. We used these to identify anatomical landmarks to assist the surgeon in the planning of a safe and effective anterior clinoidectomy.
我们在尸体头部研究了前床突（ACP）及其毗邻结构的手术解剖。我们特别关注前床突与毗邻结构之间的解剖关系，以确定安全的前床突切除术的手术标志。解剖了35个尸体头部，并在55个颅骨侧检查了前床突区域。我们观察到，在8个侧中，前床突由蝶窦气化。仅在8个侧中发现了颈动脉床突孔。眼外神经在蝶骨小翼的下外侧向前走行至上眶裂，动眼神经最靠近。在9个侧中，颈动脉动眼神经膜的后外侧区域薄且不完整。本研究阐明了前床突与其周围结构之间的解剖关系，并确定了所经历的主要变异。我们利用这些来识别解剖标志，以协助外科医生规划安全有效的前床突切除术。
