【摘要】：目的:应用放射影像学资料对不明身份个体进行性别判定是法医学研究的重要内容。额窦由于其独特的解剖学特点以及其高度的个体差异,已成为法医学进行个体识别的重要研究对象,但应用额窦相关指标进行性别判定的研究国内外还鲜有报道。因此本研究旨在通过测量分析新疆汉族成人头颅侧位片中额窦影像的相关指标以获得一种新的性别判定方法,为新疆地区牙科法医学或考古学等领域提供更为可靠的的理论基础。方法:本研究以新疆地区475位正常汉族成年个体的头颅侧位片为研究对象(男246,女229),应用专业的测量软件—NemoCeph NX。测量出每一张头颅侧位片中额窦的最大高度与最大深度,计算出额窦指数(FSI)(额窦最大高度与最大深度的比值);描画出头颅侧位片中额窦影像的最大边界,计算出额窦面积(FSA),将以上数据进行统计分析。结果:通过Fisher判别分析方法,得出:应用头颅侧位片中FSI与FSA为研究指标对成年个体性别进行判别,其正确判别率为76.6%。结论:本研究得出:应用成年个体FSI与FSA为研究指标可以获得准确率较高的性别推断。因此,在法医学、考古学等领域中应用其他研究方法无法正确识别个性别时,应用死者头颅侧位片中FSI与FSA可以辅助研究者对个体性别做出推断。
[Abstract]:Objective: to use radiographic data to determine the sex of unidentified individuals is an important part of forensic research. Due to its unique anatomical characteristics and high individual differences, frontal sinus has become an important object of forensic individual identification. However, there are few reports at home and abroad on the application of frontal sinus related indicators to gender determination. Therefore, the purpose of this study is to obtain a new method of sex determination by measuring and analyzing the related indexes of frontal sinus images in lateral head images of Han nationality adults in Xinjiang. To provide a more reliable theoretical basis for dental forensic medicine or archaeology in Xinjiang. Methods: in this study, the lateral cephalic radiographs of 475 normal adults of Han nationality in Xinjiang were studied (male 246, female 229), and the professional measurement software-NemoCJoseph NX. was used. The maximum height and depth of frontal sinus were measured in each lateral cephalic image, and the ratio of maximum height to maximum depth of frontal sinus index (FSI) () was calculated. The area of frontal sinus was calculated and analyzed by (FSA),. Results: by means of Fisher discriminant analysis, it was concluded that FSI and FSA in lateral cephalic radiography were used to judge the sex of adult individuals, and the correct discriminant rate was 76. 6%. Conclusion: using adult individuals FSI and FSA as research indexes can obtain higher accuracy of sex inference. Therefore, when other research methods in forensic science, archaeology and other fields can not correctly identify the gender, the use of FSI and FSA in lateral radiographs of the deceased can assist researchers to infer the individual sex.
