【摘要】：[研究背景及目的] 应用放射影像资料进行同一认定是法医放射学重要的研究方向之一,而额窦独特的形态特征又使其成为头颅中最常使用的识别标志。额窦形态具有高度个人特异、终生不变、难于伪造、便于观察和测量等特点,可以用于同一认定。国外法医学中有许多应用额窦放射影像资料进行同一认定的研究和案例报道,研究多按一定标准投射体位进行。本研究采用计算机放射成像(Computer radiology,CR)片探讨不同投照体位的额窦用于同一认定的观测指标,以编制简单易行的额窦同一认定识别编码,同时比较观测指标性别差异是否具有统计学意义,并研究我国四川省汉族人群额窦形态学特点。 [方法] 按照纳入标准收集额窦CR片,对额窦特征即各宽度比值和形态学特征应用描述性研究方法进行描述性研究和统计分析。 [结果] (1) 选用额窦的8项识别指标即:左右侧额窦不对称性A_1、额窦与眼眶宽度之比R_1、最大额窦宽度的侧别、左右侧额窦上缘弓形弯曲的数目、左右侧额窦部分隔的数目、额窦中间隔的位置,以此顺序编制8位数字的额窦构型同一认定的识别编码;(2) 额窦形态性别差异无统计学意义(P0.05);(3) 我国四川省汉族人群额窦双侧缺失率为8.70%,单侧
[Abstract]:Background and objective: using radiographic data to identify the same image is one of the important research directions of forensic radiology, and the unique morphological characteristics of frontal sinus make it the most commonly used identification mark in the skull.The shape of frontal sinus is highly personal, invariable, difficult to forge, easy to observe and measure, and can be used in the same identification.There are many studies and case reports on the same recognition of frontal sinus radiographic data in foreign forensic science, most of which are carried out according to certain standard projection position.The purpose of this study was to use computer radiology CRA film to study the observation index of frontal sinus in different positions, so as to draw up a simple code for identifying the same recognition of frontal sinus.The morphological characteristics of frontal sinus of Han nationality in Sichuan Province were also studied.[methods] frontal sinus CR films were collected according to the inclusion criteria, and descriptive study and statistical analysis were carried out on the frontal sinus characteristics, i.e., the ratio of width to width and morphological features.[results] eight identification indexes of frontal sinus were selected, namely: dissymmetry A _ 1 of left and right frontal sinus, ratio of frontal sinus to orbital width R _ 1, side of maximum frontal sinus width, number of arcuate curvature of left and right frontal sinus, and number of septum of left and right frontal sinus.The location of the septum in the frontal sinus, in which 8 digits of the frontal sinus configuration were compiled in this order, the same recognized identification code was used in this order. (2) the gender difference of the frontal sinus morphology was not statistically significant (P 0.05)) the bilateral deletion rate of the frontal sinus in the Han population of Sichuan Province was 8.70%, and the bilateral deletion rate of the frontal sinus was 8.70% (P < 0.05).
