目的：进一步探讨鼻窦骨结构变异与鼻窦炎发生的关系。方法：对109例临床疑为鼻窦炎患者进行鼻窦冠状位CT扫描。结果：鼻窦粘膜异常改变者93例（85.3％），16例粘膜呈正常影像（14.7％）。在93例鼻窦粘膜异常改变者中，鼻窦骨结构变异为70例（75．3％），其中Haller气房出现率为31.2％，中鼻甲气化为31．2％，中鼻甲反和弯曲为10．8％，钩突气化为2．2％。结论：鼻窦骨结构变异可能是鼻窦炎致病因素之一，鼻窦炎患者骨结构变异情况应对每个患者进行具体分析，同时也要考虑到其它致病因素。
Objective: To further explore the relationship between sinusoidal structure variation and sinusitis. Methods: Coronal CT scan of 109 patients with clinically suspected sinusitis was performed. Results: 93 cases (85.3%) had sinus mucosal abnormalities and 16 cases mucosas showed normal images (14.7%). In 93 cases with abnormal changes of sinus mucosa, the skeletal structure variation of sinus was 70 cases (75.3%), including Haller atrial occurrence rate of 31.2%, middle turbinate gasification of 31.2%, middle turbinate reverse and bending 10.8%, hooked gasification to 2.2%. Conclusion: The variation of sinus structure may be one of the causative factors of sinusitis. The variation of bone structure in patients with sinusitis should be analyzed in detail for each patient, and other causative factors should be taken into account.
