摘　　要：目的 :为颅底和眶内手术提供滑车神经的解剖依据和补充国人滑车神经的体质学资料。材料与方法 :在 2 1例 (4 2侧 )正常成年人头颅标本上 ,观测滑车神经的走行及各段长度和外径。结果 :滑车神经连脑处位于下丘的外下方 ,离中线 4 5± 0 .6mm ;穿小脑幕处在后床突后外方 1 3 .7± 3 .8mm ;在海绵窦外侧壁 ,与动眼神经相距 4.5±2 .1mm ,与眼神经相距 4 2± 1 .4mm。测得滑车神经颅段、幕潜行段、海绵窦段、眶上裂段和眶段的长度及各段中部的宽度和厚度。结论 :在颅底和眶内手术时 ,应重视该神经的解剖位置并加以保护。Objective:To provide some applied anatomical data of trochlear nerves for skull base and orbit surgery and the data of trochlear nerves about Chinese constitution.Methods:Twenty one skull cadavers of normal adults were dissected.The course of trochlear nerves was observed and measured.The length and diameter of each part were measured in trochlear nerves.Results:The trochlear nerves attached to mesencepholon at 4.5±0.6 mm lateral to midline and inferiolateral to inferior colliculus.The nerve entered into tentorium of cerebellum at 13.7±3.8 mm posteriolateral to the posterior clinoid process.The nerve lay in 4.5±2.1 mm inferior to oculomotor nerves and 4.2±1.4 mm superior to ophthalmic nerves in the lateral part of cavernous sinus.The length and diameter of skull part,tentorium part,cavernous part,superior orbital fissure part and orbit part were presented.Conclusion:The nerve must be made out and protected in the operation of skull base and orbit surgery.
