【摘要】 目的研究不同投照体位CR片上额窦用于同一认定的观测指标,以编制特异的识别编码。方法用两宽度比值与形态学描述相结合的方法观测额窦CR片,并采用描述性研究方法进行描述性研究和统计分析。结果以额窦不对称性AI、额窦与眼眶宽度之比RI、最大额窦宽度的侧别、额窦上缘弓形弯曲数目(左侧、右侧)、额窦部分隔数目(左侧、右侧)、额窦中间隔位置等8项指标,编制8位数字的额窦构型同一认定编码;额窦形态性别差异无统计学意义(P>0.05)。结论额窦形态高度个人特异,可以用于同一认定,但不能用作性别判断。更多还原

【Abstract】 Objective To study identical indexes of frontal sinus in different locative computer radiology. Methods Frontal sinus radiographs were analysed by combining indexes of kinds of distances and patterns, further using descriptive study to describe frontal sinus and to analyse data statistically. Results The 8-identical classification of frontal sinus was proposed, basing on the ratio of frontal sinus width and orbit width, the bilateral asymmetry, the superiority of side, the numbers of arches of upper borders(left and right), the partial septa(left and right)and the location of the central septa. There was no statistical significance of sinus between sexes(P>0.05). Conclusion Frontal sinus is tremendous inter-individual variation so it can be used for identification, but it can not be used for sex determination.更多还原
