摘要： 目的从法医学同一认定的视角探究柯氏位额窦计算机X线摄影(computer radiography,CR)的形态学分类,并结合识别指标的数字编码,构建X线影像同一认定体系。方法收集400例四川汉族成年人额窦标准柯氏位CR片,以两侧眼眶上缘均相切的直线与额窦的位置关系对额窦形态学特征进行分型研究,并对额窦识别指标进行数字编码。结果提出额窦CR片影像学特征6类分型,筛选出额窦不对称性、最大额窦面积的侧别、同侧额窦面积与眼眶面积比、额窦上缘弓形弯曲数、额窦部分分隔位置、额窦中间隔位置等8项识别指标。结论提出了先作分型鉴别,再用所选取的8项指标对额窦形态进行识别编码的柯氏位额窦CR片影像同一认定的新思路。

Abstract: Objective To explore morphological classification of the Caldwell view of frontal sinuses in computer radiography(CR) for forensic identification and to construct a forensic identification system with digital X-ray films with assistance of identification indexes coding.Methods Four hundred CR films of the Caldwell view of frontal sinus were selected from Sichuan Han ethnic Chinese.The frontal sinuses were classified according to the relationship between the tangential line above the upper edge of the bilateral orbits and the location of the frontal sinus.Then to code the identification indexes for the frontal sinus.Results The Caldwell view of frontal sinuses were classified into 6 categories.Eight identification indexes for the frontal sinus were identified,including degree of asymmetry,superiority of side,ratio of the left frontal sinus area and orbit area(ALFS/ALOR),ratio of the right frontal sinus area and orbit area(ARFS/AROR),outline of the left upper border,outline of the right upper border,occurrence of partial septa and location of frontal median margin.Conclusion Initial identification by the Caldwell view classification of frontal sinuses followed with coding the frontal sinuses with 8 indexes is likely a novel approach for forensic identification of the frontal sinuses in CR.
