钩突解剖形态变异与慢性鼻窦炎关系的评价

The Variation and Clinical Significance of Uncinate Process

目的通过副鼻窦冠状住CT研究钩突形态变异及其临床意义。方法分析128例(256侧)经CT检查的病人资料,选择冠状位CT片观测以下内容:钩突头端的附着部位,测量钩突高度、角度及筛漏斗宽度。将钩突不同附着类型的钩突高度和角度分别进行两两比较,并分析钩突常见解剖变异分布情况及其与慢性鼻窦炎的关系。结果钩突头端的附着部位有4种类型:钩突分叉型(41.01%);中鼻甲型(26.17%);纸样板型(17.96%);颅底型(14.38%)。这4种类型的发病率在鼻窦炎组与非鼻窦炎组有显著差异。钩突高度、钩突角度和筛漏斗宽度及钩突形态变异在鼻窦炎组与非鼻窦炎组有明显差异。结论钩突形态变异与慢性前组鼻窦炎关系密切。

Objective To study the variation and significance of uncinate process with coronal CT. Methods By analyzing the clinical information of 128 cases （256 sides） who all had undergone CT detection. The attachment of the superior part of the uncinate process was observed and measured on coronal CT. The relationship between the image anatomy and the sinusitis was also studied. The height and angle of four kinds of different uncinate process were compared each other. Results The superior part of the uncinate process was attached to four different structures such as the fraction （41.01%）, the middle turbinate （26. 17% ）, the pagyraceous lamina （ 17.96% ）, and the skull base （ 14. 38% ）. The incidence of the four attachments was significantly different between the sinusitis patients and normal adults. The height, angle, width and the variation of uncinate process were statistically different in two groups. Conclusions The variation of the uncinate process plays an important role in the initiation and development of chronic sinusitis.
