摘要
目的探讨中鼻甲气化的CT表现、诊断标准及分类,评价中鼻甲气化与慢性前组鼻窦炎的关系。方法回顾性分析248侧中鼻甲气化的CT图像,观察冠状位图像中鼻甲气化表现特征,尝试界定中鼻甲垂直部气化标准及垂直部高位与低位气化的标准。分析中鼻甲气化与慢性前组鼻窦炎的关系。结果不同类型中鼻甲气化具有不同的CT表现。鼻窦炎与无鼻窦炎者的中鼻甲气化数量差异有统计学意义。不同中鼻甲气化类型之间慢性额窦炎的数量差异无统计学意义,慢性前组筛窦炎及上颌窦炎的数量差异有统计学意义。鼻窦炎程度积分与中鼻甲垂直部低位气化的大小之间无相关性。结论鼻窦冠状位CT对于中鼻甲气化观察分析有重要价值。中鼻甲气化很可能是慢性前组鼻窦炎的潜在危险因素,而且不同气化类型引起鼻窦炎的危险性不尽相同。
Objective To investigate the CT findings,diagnostic criteria and categories of concha bullosa,so as to evaluate the relationship between concha bullosa and chronic anterior nasal sinusitis.Methods CT images of 248 sides concha bullosa were analyzed retrospectively.CT manifestations of concha bullosa on coronal images were analyzed.The CT criteria for concha bullosa of perpendicular portion and the identification criteria between upper and nether perpendicular portion were observed.The relationship between concha bullosa and chronic anterior nasal sinusitis was analyzed.Results Various CT characteristic appearances corresponded with various types of concha bullosa.Statistical difference of pneumatization number between sinusitis group and non-sinusitis group was found.No difference of chronic frontal sinusitis number in various pneumatized types was found,but the difference of chronic anterior ethmoid sinusitis and maxillary sinusitis number was significant.There was no correlation between the scores of sinusitis degree and the size of concha bullosa of nether perpendicular portion.Conclusion Coronal CT images are significant to observe and evaluate concha bullosa.Concha bullosa is probably a potential risk factor for chronic anterior nasal sinusitis,and the degree of risk is somehow different according to different pneumatized types.
