汉族群体额窦形态特征的研究

目的观察汉族群体额窦的形态结构特征,开发用于个人识别的额窦观察指标。方法应用AdobeImageReady软件分析额窦,观察24项指标,利用数字编码描述和分类额窦。结果观察227例样本,其中94例样本双侧额窦存在,及一侧存在至少两个弓形峰。24项指标的变异度和个人识别率为0.022-0.901,24项指标累计个人识别率为0.992。结论24项指标在不同个体变异较大,可用于个人识别。

Study on morphological characteristics of the frontal sinuses in Han ethnic group

Objective To observe the morphological characteristics of the frontal sinuses in Han ethnic group and develop the parameters of the frontal sinuses applied to personal identification. Methods The frontal sinuses were analyzed using Adobe ImageReady software. A total of 24 parameters was observed, and each parameter of the frontal sinus was classified using the code number according to its variation, and the patterns of the frontal sinus were described and classified using the combined code. Results 227 samples, and 94 samples with bilateral fontal sinuses and more than one arcade of the upper border of the unilateral frontal sinus were analyzed. The diversities and the discrimination probabilities of the parameters ranged from 0. 022 to 0. 901, and the cumulative discrimination probability was 0. 992. Conchisions These parameters of the frontal sinus that were variability to different persons could be applied to personal identification.
