窦口鼻道复合体解剖变异与鼻窦炎相关性的MSCT研究

The correlation between the anatomic variations of the ostiomeatal complex and chronic sinusitis by MSCT

目的 :利用多排螺旋CT(MSCT)观察窦口鼻道复合体的多种解剖变异,探讨窦口鼻道复合体(OMC)多种变异与鼻窦炎的相关性。方法:随机抽取我院做副鼻窦MSCT检查的291例受检者,观察并记录不同个体OMC发生变异的情况。使用统计学软件15.0对所得数据进行卡方检验,对比OMC解剖变异发生率在鼻窦炎与非鼻窦炎组间的差异性有无统计学意义。结果:经骨算法及多层面重建技术得到的图像能清晰显示OMC结构、变异及病变情况。鼻窦炎组多种变异发生率均高于非鼻窦炎组,其中钩突内移、外移、上端卷曲及分叉、筛泡过度气化、鼻丘过度气化的发生率在鼻窦炎及非鼻窦炎组之间的差异有统计学意义(P<0.05)。结论:MSCT多层面重建技术能清晰显示OMC结构、变异及病变情况。OMC解剖变异(钩突内移、外移、上端卷曲及分叉、筛泡过度气化、鼻丘过度气化)与鼻窦炎发病有明显相关性。

Objective： To study the correlation between the anatomic variations of the ostiomeatal complex （OMC） and si- nusitis through the observations by multi-slice spiral CT（MSCT）. Methods： 291 subjects who were examined with MSCT in our hospital were randomly selected in this study. The anatomic variations of the OMC were observed and recorded. Statistical analysis was done by Chi-square test with SPSS 15.0. Then, occurrence in the non-sinusitis and the sinusitis group was compared. Result： The OMC＇s structure, variations and lesion could be clearly shown by the bone reconstruction and multi- plannar reconstruction. The variation rate of sinusitis group was higher than non-sinusitis group. There is significant difference between the sinusitis group and non-sinusitis group with the movement and curl of uncinate, hyperpneumatization of agger cells and ethmoidalis（P〈0.05）. Conclusion： The OMC＇s structure, variations and lesions can be clearly observed by using mul- tiplannar reformation techniques of MSCT. There is an intimate relationship between the anatomic variations of OMC（movement and curl of uncinate, hyperpenumatization of agger cells and ethmoidalis） and the morbidity of sinusitis.
