摘　　要：目的应用磁共振成像(MRI)方法对颞部软组织厚度行多平面量化分析,初步建立颞部软组织厚度的测量数据集,为颞部年轻化诊疗提供临床参考。方法采集2016年12月至2021年12月于重庆医科大学附属第一医院行MRI检查的我国西南地区汉族人群头颅高清影像进行回顾性分析。共设置12个测量点指标,较平均分布于颞部上、中、下、前、后区域,包括:颞部全层软组织厚度(NA、Na、MA、Ma、GA、Ga)及颞肌厚度(NB、Nb、MB、Mb、GB、Gb)。按性别、年龄(≤30岁、31~40岁、41~50岁、51~60岁、>60岁)、身体质量指数(BMI,<21 kg/m^(2)、21~26 kg/m^(2)、>26 kg/m^(2))分为不同亚组,比较不同性别、年龄、BMI情况下的颞部软组织厚度的差异。正态分布计量资料2组间比较采用独立样本t检验,多组间比较采用单因素方差分析。结果 (1)共纳入278例患者,男140例,女138例,年龄12~82岁,平均44.5岁,BMI 18.4~33.4 kg/m^(2)。按年龄分组情况:≤30岁,56例;31~40岁,64例;41~50岁,56例;51~60岁,56例;>60岁,46例。按BMI分组情况:男性,<21 kg/m^(2) 38例、21~26 kg/m^(2) 56例、>26 kg/m^(2) 46例;女性,<21 kg/m^(2) 48例、21~26 kg/m^(2) 50例、>26 kg/m^(2) 40例。(2)男性颞部软组织普遍较女性厚,以颞肌为著,6个颞肌厚度测量指标差异均有统计学意义(P<0.05)。(3)总体上,男性颞肌在31~40岁时及女性颞肌在≤30岁时有较其他年龄组更厚的趋势;两性群体颞肌厚度在达到高点后均随年龄增长逐渐变薄。(4)两性群体颞部全层软组织均随着BMI的增加而增厚,且下颞区全层软组织较中上颞区厚。结论颞部软组织厚度与性别、年龄和BMI均存在关联;两性群体颞肌随年龄增长呈逐渐变薄趋势,而颞部全层软组织随着BMI的增加而增厚。Objective Magnetic resonance imaging(MRI)was used to perform multi-plane quantitative analysis of temporal soft tissue thickness,and the measurement data set of temporal soft tissue thickness was initially established to provide clinical reference for the diagnosis and treatment of temporal rejuvenation.Methods High definition images of Han population in Southwest China who underwent head MRI in the First Affiliated Hospital of Chongqing Medical University from December 2016 to December 2021 were randomly collected in this study.A total of 12 measuring points were set,which were evenly distributed in the upper,middle,lower,anterior and posterior regions of the temporal,including the thickness of the whole temporal soft tissue(NA,Na,MA,Ma,GA,Ga)and the thickness of the temporal muscle(NB,Nb,MB,Mb,GB,Gb).They were divided into different groups according to sex,age(≤30 years old,31-40 years old,41-50 years old,51-60 years old,>60 years old)and body mass index(BMI<21 kg/m^(2),21-26 kg/m^(2),>26 kg/m^(2)).The differences of temporal soft tissue thickness under different gender,age and BMI were compared.Independent sample t-test was used for comparison of normal distribution measurement data between two groups,and one-way analysis of variance was used for comparison between multiple groups.Results(1)A total of 278 patients were included,including 140 males and 138 females,ranging in age from 12 to 82 years,with an average age of 44.5 years,and BMI of 18.4 to 33.4 kg/m^(2).According to age group:≤30 years old,56 cases;31-40 years old,64 cases;41-50 years old,56 cases;51-60 years old,56 cases;>60 years old,46 cases.According to BMI,males(<21 kg/m^(2),38 cases;21-26 kg/m^(2),56 cases;>26 kg/m^(2),46 cases)and females(<21 kg/m^(2),48 cases;21-26 kg/m^(2),50 cases;>26 kg/m^(2),40 cases)were grouped.(2)Male temporal soft tissue was thicker than female,especially temporalis muscle,and the difference in 6 temporal muscle thickness measurements were statistically significant(P<0.05).(3)In general,the temporalis muscle in ma
