摘　　要：目的:运用Mimics软件测量正常人群髁突体积、表面积和MI值,探讨不同位置、性别、年龄的髁突形态特点,为确立正常人群髁突体积和表面积参考值提供参考。方法:从上海交通大学附属第六人民医院放射科就诊患者中选取符合纳入标准的研究对象300例,根据年龄分为3组:组1(18~24岁),组2(25~34岁),组3(35~44岁)。每组100例,其中男女各50例。然后进行多层螺旋CT检查,并运用Mimics17.0软件对双侧髁突进行三维重建,计算髁突体积、表面积和MI值。结果:左右侧髁突体积、表面积和MI值均无明显差别,男性髁突体积、表面积都要大于女性(P<0.05),但男女之间髁突MI值无显著性差异。不同年龄个体之间髁突的体积和表面积未见明显差别,而35~44岁个体的MI值要大于18~24岁个体(P<0.05)。结论:Mimics软件可以有效地测量髁突的体积和表面积,并为确立正常人群髁突体积和表面积参考值提供参考。Objective：To calculate the volume,surface area and morphometric index（MI）of condyle in normal population by Mimics 17.0,and to investigate the morphological characteristics at different positions,sex and age,so as to establish reference value of normal population.Methods：Three hundred subjects were enrolled in our study from the radiology department of The Affiliated Sixth People＇s Hospital,Shanghai Jiao Tong University.They were divided into three groups according to ages：group 1（18-24）,group 2（25-34）,and group 3（35-44）.Each group contains 100subjects（50males and 50females）.Then they were examined by MSCT.All images were reconstructed by Mimics.Results：The differences of condylar volume,surface area and MI between right and left sides were not significant.The condylar volume and surface area were greater in males than in females（P〈0.05）,while their MI showed no significant difference.We found no statistically significant difference in volume and surface area among three groups.However,the MI of group 1was significantly lower than that of group 3（P〈0.05）.Conclusion：Mimics can measure the volume and surface area of condyle effectively,and reference values of the condylar volume and surface area in normal population can be established.
