目的探讨CT技术的应用对鼻区骨折法医学鉴定的影响,发现现行鉴定标准存在的问题提出修订意见。方法 运用χ2检验比较两个不同时期分别以X线和CT为主要鉴定依据评定为轻伤的案件,探究医学放射影像检查技术对鼻区骨折鉴定意见的影响程度。结果 发现CT技术对鼻区骨折的鉴定结果的影响,与X线比较,其差异有统计学意义,并暴露出基于X线影像技术的鼻骨损伤鉴定标准条款不再适应目前鉴定实践状况的问题。结论 在CT技术广泛应用后,现行的鼻骨损伤鉴定标准条款不能很好地适应医学发展,有必要重新制定基于CT技术的鼻区骨折鉴定标准。

Abstract:Objective To discuss the effect of CT technique applied in forensic medical examination of nasal fracture,and to propose a revision opinion on the current examination standard.Methods Cases that were concluded as minor injury in two different periods according to the results of X-ray and CT were collected.The influence of these two techniques on the forensic conclusion of nasal fracture was analyzed by Chi-square Test.Results Compared with X-ray,the application of CT has a more significant impact on the examination conclusions of nasal fracture.Therefore,the standard based on X-ray results is not consistent with the present situation any more.Conclusion Since the CT technique has been applied widely,a new examination standard should be made on the basis of CT technique.
Key words:CT;nasal fracture;forensic medicine.
鼻区骨折在法医临床学鉴定中较为常见的损伤,《人体轻伤鉴定标准(试行)》(以下简称《轻伤》)第十条(一)规定“鼻骨粉碎性骨折,或者鼻骨线形骨折伴有明显移位”,其伤情为轻伤。该条款在制订时的影像学基础是X线,但当CT得到广泛应用后,鉴定变得复杂,除了鼻骨粉碎性骨折以外,鼻骨相邻骨如上颌骨额突、筛骨、额骨鼻突等鼻区骨性结构骨折较前易于诊断,如何参照本条鉴定成为新问题。本文通过两组数据的统计学检验,研究影像学检查技术对鼻区骨折鉴定意见的影响程度,进而指出《轻伤》第十条(一)规定滞后于法医临床实践,认为需要将鼻区骨折作为一个有机的整体进行规定,修订相应鉴定标准。……
