121例儿童钩突变异螺旋CT表现与鼻旁窦炎症的相关性

Correlation analysis between spiral CT findings in anatomical variant of the uncinate process and paranasal sinusitis in 121 children

目的：探讨儿童鼻旁窦炎症与钩突解剖变异的相关关系。方法：对121例2～13岁儿童进行高分辨率螺旋CT容积扫描及多平面重建，测量钩突偏曲角度并与鼻窦炎症进行二项式logistic相关回归分析。结果：儿童鼻窦钩突形状、附着形式及角度变异较大，且随窦腔浑浊度不同导致测量角度有较大变化，并与鼻窦炎症无显著统计学关联。结论：儿童钩突形状及测量偏曲角度存在变异较大的特点，除钩突角度特别接近水平外，与鼻窦炎症不存在明显相关性。

Aim：To explore the relationship between the anatomical variant of the uncinate process and the chronic sinusitis. Methods： The anatomical variant of the angle of uncinate process were observed and measured on 121 volume CT and MPR images respectively. The relationship between the image anatomy and the sinusitis was also studied with Binary Logistic Regression. Results： There are highly multi-variant of anatomy structure of the uncinate process. The different results usually correlated to the different degree of sinusitis. The angle of uncinate process were not correlated to the score of the sinus opacity of sinusitis patients. Conclusion：There are highly multi-variant of anatomy structure of the uneinate process. Probably the angle of uncinate process do not play a great role in the initiation and development of chronic sinusitis unless it approach to aclinic angle, because the significant correlation do not exist between them.
