现代汉族年轻女性“倒三角脸”与“方脸”下面部颅颌面软硬组织三维CT的测量研究[摘要]目的:探讨现代汉族年轻女性“倒三角脸”与“方脸”下面部颅颌面软硬组织量化标准及相互关系,为下面部轮廓改型提供理论依据。方法:测量15例现代汉族年轻女性下面部软硬组织形态学指标(倒三角脸7例,方脸8例),应用SPSS17.0进行统计学分析,分析两种脸型在下面部软硬组织上的区别。结果:①两种脸型下面宽、下面高、咬肌厚度、中面宽/下面宽、下面宽/下面高有显著性差异(P〈0・01);②下面宽与咬肌厚度正相关,与下颌角角度负相关;下面高与下颌角角度正相关,与咬肌厚度负相关;下颌角角度与咬肌厚度负相关;③下面部软硬组织测量项冃左右对称性较好,差异在正常范围内。结论:方脸与倒三角脸下面部软硬组织差异较大,横向差异以咬肌厚度差异为主,纵向以下面高差异为主。多数人通过肉毒素瘦咬肌结合隆须术,可缩窄下面宽、延长下面高,使方脸向倒三角脸转变。该方法简单易行,患者接受度高,效果显著。[关键词]面型;下面部;形态学测量;软硬组织相关性[中图分类号1R783.5R62[文献标识码]A[文章编号]1008-6455(2014)14-1135-04The3DCTmeasurementstudyofthelowerfaceof,zinvertedtriangleface^and"squareface^ofyoungIlanwomenZHOURong-ronghZHAOQi-mingl,LIUMiao2(DepartmentofBurnandPlasticSurgery,The117thHospitalofPLA,Hangzhou310013,Zhejiang,China;2.DepartmentofRadiology,The117thHospitalofPLA)Abstract:ObjectiveDiscussethestandardandrelationshipofsoftandhardtissueofthelowerfaceof〃invertedtriangleface"and"squareface〃ofyoungIlanwomen.Thentoprovideatheoreticalbasisforfacialcontourmodification.MethodsMeasuringthemorphologyindexof15youngHanwomen(7casesof〃invortodtriangularface",8casesof"squareface").AndanalyzingthedifferencebetweenthetwokindsoffacewithSPSS17・0.Results①Therearesignificantdiffereneeinangleofthemandiblebreadth,lowerfaceheight,massetermusclethickness,bizygomaticwidth/angleofthemandiblebreadth,andangleofthemandiblebreadth/1owerfaceheight(P<0.01)•②Therearepositivecorrelationbetweenangleofthemandiblebreadthandmassetermusclethickness,lowerfaceheightandthemandibularangle.Andnegativecorrelationbetweenangleofthemandiblebreadthandthemandibularangle,lowerfaceheightandmassetermusclethickness,themandibularangleandmassetermusclethickness•③Thesoftandhardtissueofthelowerfacehasgoodsymmetry.Thedifferencesbetweenleftandrightfacesareinnormalrange.ConclusionSignificantdifferencescanbeseeninthesoftandhardtissueofthelowerfaceofzzinvertedtriangular^and"square〃・Massetermusclethicknesscontainsthehorizontaldifference・Lowerfaceheightcontainsthelongitudinaldifference.Manypatientscanshortenangleofthemandiblebreadthandprolonglowerfaceheightwithinjectingbotoxtomassetermuscleandchinaugmentation.Themethodissimple,withhighacceplaneeandgoodeffect・Keywords:faceshape;lowerface;morphologicalmeasurement;relationshipbetweonsoftandhardtissue客观、定量的测量分析不同脸型颅颌面软硕组织的形态,特别是下面部软硕组织的形态,对指导面部轮廓改型具有重要的指导意义,但相关文献甚少。现有的文献多集中在大体软组织测量[1-2]或头颅骨组织的测量上[3],并未进行脸型分类测量。研究表明,倒三角脸(瓜子脸)是H前最漂亮的脸型[4],下面部曲线柔和,符合东方人的审美特点。而方脸下面部较宽,失去女性阴柔美。因此,我们以倒三和脸和方脸为例,利用电子计算机X射线断层扫描技术(ComputedTomographyCT),对两种脸型下面部软硬组织各项指标进行测量和分析,为指导轮廓改型手术提供理论依据和指导。我科自2012年7月对15例现代汉族年轻女性(倒三角脸7例,方脸8例)行头颅三维CT成像,测量下面部软硬组织各项形态学指标,并对其进行分析。...
