鼻中隔偏曲与鼻窦炎关系的CT影像学研究

Computed tomographic analysis of the relationship between nasal septal deviation and sinusitis

目的本文应用鼻窦冠状位CT对鼻中隔偏曲进行观察,并探讨其与鼻窦炎的关系。方法分析754例患者的CT片,从中分出正常组与鼻窦炎组。统计这两组中鼻中隔偏曲的发生率,并分析其与鼻窦炎的关系。再进一步统计分析高位偏曲和低位偏曲的发生率及其与鼻窦炎的关系。结果鼻中隔偏曲的发生率在两组间分布差异无显著性(x2=1.86,P>0.05),但鼻窦炎组中鼻中隔高位偏曲的发生率明显高于正常组(x2=5.06,P<0.05)。对于鼻中隔高位偏曲,无论是同侧还是对侧窦口鼻道复合体区域的解剖变异的发生率在两组间的分布均有显著性差异(P<0.05)。结论鼻中隔高位偏曲可引起窦口鼻道复合体区的解剖异常,与鼻窦炎的发生相关。

Objective Coronal CT scan of the paranasal sinuses was carried out to observe the relationship between nasal septal deviation and sinusitis in patients.Methods 754 coronal CT scans were divided into normal group and sinusitis group.The prevalence of nasal septal deviation and the prevalence of upper deviation and low deviation in these two groups were calculated and analyzed.Results The prevalence of nasal septal deviation between normal group and sinusitis group was similar with no significant difference between them（Х^2=1.86,P〉0.05）,however,the prevalence of upper nasal septal deviation was higher in sinusitis group than in normal group（Х^2=5.06,P〈0.05）.The prevalences of anatomic variations of the ipsilateral or controlateral ostiomeatal complex of the upper nasal septal deviation were significant differences between these two groups（P〈0.05）.Conclusion The upper nasal septal deviation can cause the anatomic variations of ostiomeatal complex,which might be related to the occurrence of accessory nasal sinusitis.
