鼻窦骨结构变异及其临床意义(鼻窦CT扫描分析)

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。

CLINICAL SIGNIFICANCE OF ANATOMIC VARIATIONS IN PARANASAL SINUS BONE STRUCTURE(CT ANALYSIS)

Objective: To investigate the relationship between paranasal sinus bone structure anatomic variations and sinusitis. Methods: A detailed analysis of coronal plane CT scans of paranasal sinuses obtained in 109 patients for sinus-like complaints was conducted. Results: The mucosal abnormalities and normalities of paranasal sinuses were respectively detected in 93(85. 3 % ) and 16(14. 7% ) of the 109 patients. The paranasal sinus bone structdre anatomic variations were noted in 70(75. 3 % ) of the 93 patients with mucosal abnormalities, including Haller's cells in 31. 2 %, pneumatization and paradoxical curvature of middle turbinate in 31. 2%and 10. 8%, and pneumatization of the uncinate process in 2. 2%. Conclusion:The sinus bone structural variations may be a predisposing factor for sinusitis. Assessment of pathogenicity of anatomic variations needs to be carried out only on a patient-by-patient basis. Simultaneously, other etiological factors should also be taken into consideration.
