摘要
目的量化研究鼻鼻窦解剖变异与慢性鼻窦炎的发病的关系。方法用自行开发的计算机图像分析系统定量分析９１例慢性鼻窦炎患者的冠状位鼻窦ＣＴ，观测指标包括：骨性解剖结构变异（包括中鼻甲气化、反常曲线中鼻甲、Ｈａｌｅｒ气房、鼻中隔偏曲、上颌窦发育不良、鼻丘气房、钩突气化）、筛漏斗、钩突角度、筛泡等，测量相应结构的冠状位截面积、角度、长度。应用统计软件ＳＰＳＳ进行统计。结果全中甲或中甲下部气化的发生率随前筛、上颌窦内软组织影增厚而升高；有额窦炎组病人的鼻丘气房最大纵向垂径明显大于无额窦炎组（分别为１１．７±５．５ｍｍ和８．５±３．７ｍｍ，Ｐ＜０．０１）；Ｈａｌｅｒ气房在上颌窦炎组和非上颌窦炎组的发生率无显著差异，但前组发生炎症的Ｈａｌｅｒ气房明显多于后组（分别为７７．８％和３３．３％，Ｐ＜０．０５），且前组Ｈａｌｅｒ气房的冠状位截面积明显大于后组（分别为９１．６±１７．８ｍｍ２和４１．６±１２．６ｍｍ２，Ｐ＜０．０５）；钩突角度随上颌窦内软组织增厚而减小；筛泡冠状位截面积随前筛窦内软组织增厚而增大（Ｐ＜０．０１）。结论某些鼻、鼻窦解剖变异与慢性鼻窦炎的发病相关。
Objective To understand the etiology of chronic sinusitis. Methods Ninety one coronal CT scans of chronic sinusitis were analysed with mutimedia software developed by the authors. Sinus CT images were scanned into multimedia computer and the subtle anatomic structures such as pneumatization of the middle turbinate, agger nasi cell, Haller's cell, septal deformity , maxillary sinus hypoplasia , abnormality of uncinate process and ethmoid bulla and so on were measured.The results were analysed by the statistical software SPSS. Results The penumatization rate of total or inferior part of middle turbinate correlated positively to the inflammation of anterior ethmoid and maxillary sinuses. Compared with patients with normal frontal sinuses, the vertical diameters of agger nasi cells of patients with frontal sinusitis were larger(11.70±5.50 mm and 8.54±3.67 mm respectivevy, P <0.01).Compared with patients with normal maxillary sinuses, the Haller's cells of patients with maxillary sinusitis were larger (77.8% and 33.3% , P <0.05)and the amount of inflammatory Haller's cells of the latter was more abundant than that of the former(91.6±17.8 mm 2 and 41.6±12.6 mm 2, respectively, P < 0.05). The deviation of uncinate process was one of the factors of maxillary sinusitis .The sizes of ethmoid bullae increased with the soft tissue thickening in anterior ethmoid sinus, the large ethmoid bulla may cause anterior ehmoid sinusitis. Conclusion Some anatomic variations may play a role in chronic sinusitis.
