摘　　要：目的：对高分辨率ＣＴ诊断颞骨骨折的作用进行评价。材料和方法：对５０例颞骨外伤，临床有耳出血、脑脊液漏、面神经麻痹或感觉性耳聋的患者均行高分辨率ＣＴ横断及冠状面扫描，１例同时行矢状面扫描。结果：发现乳突、鼓室部骨折４０例，外耳道骨折８例，听骨脱位１８例，面神经管骨折１７例，骨迷路骨折６例，内耳道底骨折３例，累及前庭导水管及颈静脉孔各３例。结论：高分辨率ＣＴ能确定骨折部位，并显示软组织变化，如中耳出血及脑脊液漏。高分辨率ＣＴ可为诊断颞骨外伤提供可靠依据。Purpose:ToevaluatehighresolutionCT(HRCT)indiagnosisoftemporalbonetrau-ma.Materialsandmethods:AxialandcoronalHRCTwereperformedin50patientswithhistoryoftemporalbonetrauma,andsymptomsofbleedingfromear,CSFleakage,facialnervepalsy,sensorydeafnessetc.AdditionaldirectsagitalHRCTwasperformedinonecase.Results:Fractureinvolv-ingthemastoidandaticregionswasfoundin40cases,theexternalauditorycanalin8cases,thefa-cialnervecanalin17cases,theoticcapsulein6casesandtheinternalauditorycanalin3cases.Os-siculardisruptionwasidentifiedin18cases.Vestibularaqueductandjugularfossawereinvolvedin3caseseach.Conclusion:HighresolutionCTcouldlocalizethefractureanddepictthesoft-tissueab-normalities,suchasbloodorCSFinthemiddleear.Itwasconsideredtobethemodalityofchoiceindiagnosisoftemporalbonetrauma.
