摘 要:目的通过CT三维重建探讨眶上裂与颈内动脉的相对位置关系,从影像学角度为眶尖部手术的安全解剖提供参考。方法对64例(128侧)患者头颈部CT血管造影检查进行分析,使用Mimics 21.0软件进行三维重建,在三维立体模型上测量眶上裂内侧界、下界以及内上界至颈内动脉最前凸处、近环和远环的距离;记录患者的性别、年龄以及蝶窦气化情况等解剖变异,分析上述数据与所测结果之间的相关性。结果眶上裂内侧界至颈内动脉最前凸处、近环和远环的距离分别为d1(6.32±1.98)mm、d2(7.13±2.66)mm及d3(9.88±2.29)mm;眶上裂下界至颈内动脉最前凸处、近环和远环的距离分别为d4(11.93±2.17)mm、d5(10.39±2.36)mm及d6(16.18±2.28)mm;眶上裂内上界至颈内动脉最前凸处、近环和远环的距离分别为d7(7.91±2.55)mm、d8(9.63±2.99)mm及d9(10.09±2.72)mm。男性眶上裂与海绵窦段颈内动脉的相对距离显著大于女性;在年龄<20岁的患者中,d7~d9显著小于年龄超过20岁的患者,差异具有统计学意义。蝶窦气化类型与主要测量指标d1~d6存在相关性,而蝶窦气化程度及是否存在蝶上筛房与主要测量指标均无显著相关性。结论通过CT血管造影检查的三维重建对眶上裂与颈内动脉距离的测量,可以更好地评估两者之间的相对解剖关系,对于眶尖手术操作以及安全距离的把握具有临床参考价值。Objective To explore the relative positioning of the superior orbital fissure and internal carotid artery through CT three⁃dimensional reconstruction,and to provide anatomical references for safe dissection during surgeries involving the orbital apex from a radiological perspective.Methods Totally 64 cases(128 sides)of head and neck CT angiography were analyzed and Mimics 21.0 software was employed for three⁃dimensional reconstruction.Measurements were taken on the three⁃dimensional models,including the distance from the inner boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery.Distances were also measured from the lower boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery.Additionally,measurements were taken from the upper boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery.Patient demographic data such as gender,age,and sphenoid sinus aeration were recorded,and anatomical variations were analyzed in correlation with the measured result.Results Distances were measured as follows,d1(6.32±1.98)mm,d2(7.13±2.66)mm,and d3(9.88±2.29)mm from the inner boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery,respectively.Distances were also measured as d4(11.93±2.17)mm,d5(10.39±2.36)mm,and d6(16.18±2.28)mm from the lower boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery,respectively.Distances from the upper boundary of the superior orbital fissure to the anterior convexity,proximaldural ring,and distaldural ring of the internal carotid artery were measured as d7(7.91±2.55)mm,d8(9.63±2.99)mm,and d9(10.09±2.72)mm,respectively.The relative distance between the superior orbital fissure and t
