川渝地区汉族成年人颞区软组织厚度测量分析

Analysis of temporal soft tissue thickness in Han adults in Sichuan and Chongqing region

目的 探究川渝地区汉族成年人颞区各层软组织厚度随性别、年龄变化的规律,为颞区凹陷及颞区年轻化的治疗提供参考依据。方法 收集我院影像科头颅MRI资料600例(男、女各300例),测量不同横断面颞区各点软组织厚度,比较颞区软组织厚度随性别及年龄变化的差异。结果 青年组:女性在三个横断面颞区全层软组织厚度、颞肌外组织厚度均大于男性(P<0.05);中年组:女性下颞区颞肌外组织厚度大于男性,颞肌厚度小于男性(P<0.05),男性上颞区全层软组织厚度及颞肌厚度大于女性(P<0.001);老年组:女性中下颞区颞肌外组织厚度大于男性(P<0.001),男性在三个横断面颞肌厚度大于女性(P<0.05)。男性中年组颞肌外组织厚度及颞肌厚度与青年组相比无显著差异(P> 0.05),女性中年组下颞区颞肌外软组织厚度与老年组相比无显著差异(P> 0.05),其余各年龄段川渝地区汉族成年人颞区各测量软组织厚度均随着年龄增加均变薄,差异有统计学意义(P<0.01)。结论 川渝地区汉族成人中,男性及女性颞区软组织厚度均随年龄增加而逐渐变薄。男性颞区软组织变薄以中上颞区为主,女性整个颞区均变薄,程度较男性更大。

Objective To explore the changes of soft tissue thickness in temporal region with sex gender and age of Han adults in Sichuan and Chongqing area to support the treatment of facial rejuvenation.Methods A total of 600 cranial MRI data(300 for each gender) were collected to measure the soft tissue thickness at each point in the temporal region,and to compare the temporal soft tissue thickness with gender and age.Results In the young group,the thickness of whole soft tissue and extratemporal tissue in female was higher than that in male(P <0.05).In the middle age group,the thickness of external temporal muscle of female inferior temporal region was larger than that of male,and the thickness of temporal muscle was smaller than that of male(P <0.05),and the thickness of whole layer and temporal muscle of male superior temporal region is larger than that of female(P <0.001).In the elder group,the temporal muscle thickness in males was higher than that in females(P <0.001),and there was no statistical significance in the thickness of full-thickness temporal tissue between males and females(P> 0.05).Comparing different aged group of each gender,It found that the thickness of extretemporal muscle tissue and the temporalis between male middle aged group and male young group have no significant difference(P>0.05),and the same to the thickness of low extretemporal muscle tissue between female middle aged group and female senior group.(P>0.05) The thickness of temporal soft tissue in other age groups became thinner with age,the difference was statistically significant.Conclusion Ethnic Han adults(both male and female in Sichuan and Chongqing area) thickness of soft tissue in temporal region gradually decreases with age.However,the soft tissue thinning in male’s temporal region was mainly in the middle and upper temporal region,while the thinning in female’s temporal region is the whole temporal region and it would be greater than that in male.
