摘要：
Objective To explore the correlation between ostiomeatal complex(OMC)variation, nasal septum deviation and nasosinusitis with CT imaging.Methods The clinical and imaging data of 256 patients undergoing nasal and paranasal CT examination from June 1, 2015 to May 30, 2016 were retrospectively analyzed. Patients with paranasal sinus fractures, tumors and artifacts were not included in this study.Taking the image of standard coronal MPR built with thin axial sections at the level of middle of semilunar fissure as observing image,and the direction,location and extent of OMC variations were observed and recorded. The patients were divided into two groups according to the presence or absence of nasal septum deviation.OMC mutation,the incidence of unilateral mutation,incidence of paranasal sinusitis and the incidence of unilateral bilateral nasal sinusitis between the two groups was analyzed by χ2test with two independent samples. Then according to the presence or absence of OMC mutation, the patients were divided into two groups.The incidence of paranasal sinusitis and bilateral paranasal sinusitis were compared between the two groups. Results Two hundred and fifty six cases of CT imging of parannasal sinus were included in the study,96 cases were with nasal septum deviation, 160 were with non-deviation of nasal septum. The incidence rate of OMC variation between the two groups showed significant difference(χ2=38.40,P0.05).The incidence rate between unilateral and bilateral nasosinusitis showed non-significant difference(χ2=2.25,P>0.05).Of the 256 cases,128 were with OMC variations,and 128 were with non-OMC variation.The incidence rate of nasosinusitis between the two groups showed non-significant difference(χ2=0.56,P>0.05). The incidence rate between unilateral and bilateral nasosinusitis showed non-significant difference(χ2=3.57,P>0.05). Conclusion Ipsilateral OMC variation occurred in nasal septum deviation might be a compensation to nasal cavity widening while not a obstructive factor in causing nasosinusitis.%目的 探讨窦口鼻道复合体(OMC)变异与鼻中隔偏曲、鼻旁窦炎的相关性.方法 回顾性分析2015年6月1日至2016年5月30日行鼻与鼻旁窦CT检查的256例患者的临床与影像资料,鼻旁窦骨折、肿瘤及图像有伪影者不纳入研究,于半月裂水平行冠状面多平面重建进行观察.将患者先按有无鼻中隔偏曲分为两组,采用两独立样本χ2检验分析两组间OMC变异的发生率、单双侧变异的发生率及鼻旁窦炎发生率、单双侧鼻旁窦炎发生率的差异,再按有无OMC变异分为两组,比较两组间鼻旁窦炎发生率、单双侧鼻旁窦炎发生率的差异.结果 鼻中隔偏曲组96例,鼻中隔无偏曲组160例,两组间OMC变异率的差异有统计学意义(χ2=38.40,P0.05),且两组间单、双侧鼻旁窦炎发生率的差异亦无统计学意义(χ2=2.25,P>0.05).256例中,OMC变异者128例,无OMC变异者128例,两组间鼻旁窦炎发生率的差异无统计学意义(χ2=0.56,P>0.05),且两组间单、双侧鼻旁窦炎发生率的差异亦无统计学意义(χ2=3.57,P>0.05).结论 鼻中隔偏曲鼻腔增宽侧OMC变异可能是对鼻腔增宽的一种代偿,而不是鼻旁窦炎发生的阻塞因素.
