摘　　要：目的通过高分辨率CT影像学研究,探讨蝶窦内的颈内动脉隆凸与蝶窦体积的关系。方法利用无鼻旁窦异常的350例进行螺旋CT扫描,观察蝶窦内的颈内动脉隆凸出现率,然后将观察的结果分成无颈内动脉隆凸、单侧隆凸和双侧隆凸3组,每组30例,测量每组的蝶窦体积,分析蝶窦体积与颈内动脉隆凸的关系。结果蝶窦内无颈内动脉隆凸的占70.75%(258例);蝶窦内有一侧隆凸的占8.49%(31例);有二侧隆凸的占20.74%(108例)。无颈内动脉隆凸的蝶窦体积(11.16±1.60)cm3;单侧隆凸的蝶窦体积(14.20±1.80)cm3;双侧隆凸的蝶窦体积(25.03±2.21)cm3;其组与组之间比较均有统计学意义。结论蝶窦体积与蝶窦内隆凸出现率有直接相关关系,蝶窦体积小,隆凸出现率就低;蝶窦体积大,隆凸出现率就高。Objective To investigate the relationships between the bulges of the internal carotid arteries （ICA）in the sphenoid and the volume of the sphenoid by CT study.Methods The incidence of the bulges of the ICA were observed on 350 subjects without abnormal paranasal sinus diseases by CT,and then these subjects which were drawn randomly out the results were divided into three groups（group of NO bulge of ICA,one bulge and double bulges separately）and each group consisted of 30 subjects.The volume of the sphenoid was measured and the relation between sphenoid volume and bulges of ICA were analyzed.Results Group of No bulges of ICA in the sphenoid sinus were seen in 70.75%（258 subjects）,one bulg in 8.49%（31 subjects）,and double bulges in 20.74%（108 subjects）.The sphenoid volume was（11.16±1.60）cm3 in NO bulge of ICA,（14.20±1.80）cm3 in one bulge and（25.03±2.21）cm3 in double bulges.There was significant difference between each group.Conclusions The volume of sphenoid is correlated with the incidence of the bulges in the sphenoid.If the volume of sphenoid is small,the incidence of the bulge is lower,otherwise,the larger volume with the higher incidence.
