摘　　要：目的通过影像学方法测量骶骨前庭三维可用空间的解剖参数,并探讨其临床意义。方法2015年1月至2021年1月,收集200例后环完整的骨盆CT三维重建检查资料,男110例,女90例;年龄(40.72±10.70)岁(范围21~63岁)。在CT三维重建图像上测量左、右侧S1、S2前庭宽度、高度及面积数值。根据性别及侧别分组,比较S1与S2前庭解剖参数及不同性别、侧别S1与S2前庭解剖参数的差异。结果S1前庭面积为(425.71±45.07)mm2(范围296.3~604.4 mm2),其中男性为(449.80±28.62)mm2(范围338.3~604.4 mm2),女性为(388.25±34.01)mm2(范围296.3~498.4 mm2);前庭宽度为(28.52±4.34)mm(范围17.1~36.3 mm),其中男性为(31.77±2.33)mm(范围22.46~36.30 mm),女性为(24.55±2.55)mm(范围17.1~26.1 mm);前庭高度为(21.05±2.29)mm(范围17.5~32.0 mm),其中男性为(21.34±2.37)mm(范围18.5~32.0 mm),女性为(20.69±1.60)mm(范围17.5~25.6 mm)。S2前庭面积为(230.19±35.57)mm2(范围142.5~297.3 mm2),其中男性为(258.91±28.04)mm2(范围218.3~297.3 mm2),女性为(205.61±24.12)mm2(范围142.5~258.6 mm2);前庭宽度为(15.94±1.72)mm(范围12.4~20.3 mm),其中男性为(16.51±1.59)mm(范围14.4~20.3 mm),女性为(15.25±1.63)mm(范围12.4~18.1 mm);前庭高度为(14.30±1.20)mm(范围12.9~17.8 mm),其中男性为(15.49±1.46)mm(范围13.6~17.8 mm),女性为(13.73±0.93)mm(范围12.9~16.1 mm)。S1与S2前庭宽度、高度及面积均存在显著差异(前庭宽度:t=3.934,P<0.001;前庭高度:t=3.692,P<0.001;前庭面积:t=4.816,P<0.001)。男、女性S1前庭宽度、S1前庭高度、S1及S2前庭面积差异均有统计学意义(S1前庭宽度t=2.969,P=0.003;S1前庭高度t=0.316,P=0.049;S1前庭面积t=1.975,P=0.049;S2前庭面积t=2.023,P=0.044),而男、女性S2前庭宽度、S2前庭高度差异均无统计学意义。S1与S2前庭高度、宽度、面积在男、女性间比较,差异均有统计学意义(均P<0.001)。同一前庭部位左、右侧各参数差异无统计学意义。结论S1前庭径线及面积均大�Objective To measure the anatomical parameters of three-dimensional available space of S1 and S2 vestibules on Chinese adults by imaging methods,and discuss their clinical values.Methods Data of 200 cases of pelvic CT with complete posterior ring were collected from January 2015 to January 2021,included 110 males and 90 females.The ages ranged from 21 to 63 years(average,40.72±10.70 years).Then the parameters of both the left vestibule and the right vestibule of S1 and S2 such as vestibular width,vestibular height and vestibular area were measured by the three-dimensional CT reconstructions.Statistical analyses were performed among the groups which were classified according to the gender,side of vestibule to compare the difference of vestibular morphological characteristics among different groups.Results The average vestibular area of S1 was 425.71±45.07 mm2(range,296.3-604.4 mm2),which was 449.80±28.62 mm2(range,338.3-604.4 mm2)in males and 388.25±34.01 mm2(range,296.3-498.4 mm2)in females.The average vestibular width was 28.52±4.34 mm(range,17.1-36.3 mm),31.77±2.33 mm(range,22.46-36.30 mm)in males and 24.55±2.55 mm(range,17.1-26.1 mm)in females.The mean vestibular height was 21.05±2.29 mm(range,17.5-32.0 mm),with 21.34±2.37 mm(range,18.5-32.0 mm)of men and 20.69±1.60 mm(range,17.5-25.6 mm)of women.The mean S2 vestibular area was 230.19±35.57 mm2(range,142.5-297.3 mm2),which was 258.91±28.04 mm2(range,218.3-297.3 mm2)in males and 205.61±24.12 mm2(range,142.5-258.6 mm2)in females.The average vestibular width was 15.94±1.72 mm(range,12.4-20.3 mm),16.51±1.59 mm(range,14.4-20.3 mm)in male and 15.25±1.63 mm(range,12.4-18.1 mm)in female.The mean vestibular height was 14.30±1.20 mm(range,12.9-17.8 mm),15.49±1.46 mm(range,13.6-17.8 mm)in males and 13.73±0.93 mm(range,12.9-16.1 mm)in females.There were significant differences in vestibular width,height and area between S1 and S2(vestibular width t=3.934,P<0.001;vestibular height t=3.692,P<0.001;vestibular area t=4.816,P<0.001).There were significant di
