【摘要】：[研究背景及目的] 應(yīng)用放射影像資料進(jìn)行同一認(rèn)定是法醫(yī)放射學(xué)重要的研究方向之一,而額竇獨(dú)特的形態(tài)特征又使其成為頭顱中最常使用的識(shí)別標(biāo)志。額竇形態(tài)具有高度個(gè)人特異、終生不變、難于偽造、便于觀察和測(cè)量等特點(diǎn),可以用于同一認(rèn)定。國(guó)外法醫(yī)學(xué)中有許多應(yīng)用額竇放射影像資料進(jìn)行同一認(rèn)定的研究和案例報(bào)道,研究多按一定標(biāo)準(zhǔn)投射體位進(jìn)行。本研究采用計(jì)算機(jī)放射成像(Computer radiology,CR)片探討不同投照體位的額竇用于同一認(rèn)定的觀測(cè)指標(biāo),以編制簡(jiǎn)單易行的額竇同一認(rèn)定識(shí)別編碼,同時(shí)比較觀測(cè)指標(biāo)性別差異是否具有統(tǒng)計(jì)學(xué)意義,并研究我國(guó)四川省漢族人群額竇形態(tài)學(xué)特點(diǎn)。 [方法] 按照納入標(biāo)準(zhǔn)收集額竇CR片,對(duì)額竇特征即各寬度比值和形態(tài)學(xué)特征應(yīng)用描述性研究方法進(jìn)行描述性研究和統(tǒng)計(jì)分析。 [結(jié)果] (1) 選用額竇的8項(xiàng)識(shí)別指標(biāo)即:左右側(cè)額竇不對(duì)稱性A_1、額竇與眼眶寬度之比R_1、最大額竇寬度的側(cè)別、左右側(cè)額竇上緣弓形彎曲的數(shù)目、左右側(cè)額竇部分隔的數(shù)目、額竇中間隔的位置,以此順序編制8位數(shù)字的額竇構(gòu)型同一認(rèn)定的識(shí)別編碼;(2) 額竇形態(tài)性別差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05);(3) 我國(guó)四川省漢族人群額竇雙側(cè)缺失率為8.70%,單側(cè)
[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).
