鼻及鼻窦常见病变和解剖变异的CT冠状位靶扫描(附507例分析)

目的：探讨鼻及鼻窦常见病变和解剖变异的CT特征。方法：回顾性分析507例病人的冠状位CT表现。结果：慢性鼻及鼻窦炎占61．73％(313／507)；鼻息肉占22．87％(116／507)；囊肿占4．93％(25／507)，真菌性鼻窦炎占1．38％(7／507)；恶性占位性病变占0．79％(4／507)，未见异常占7．88％(40／507)。鼻中隔弯曲占65．66％(333／507)。Onodi气房占29．19％(148／507)；Haller气房占12．42％(63／507)。蝶窦发育不良占3．94％(20／507)；上颌窦发育不良占1．97％(10／507)。结论：冠状位CT靶扫描可对各种鼻及鼻窦病变做出诊断，并可显示其解剖变异的特征。

CT coronary focused scan in the common diseases and anatomic variations of nose and paranasal sinuses ( analysis of 507 cases)

Objective:To investigate the CT findings of the common diseases and anatomic variations of nose and paranasal sinuses.Methods:CT findings of coronary focused scans were analyzed in 507 patients.Results:The rate of chronic rhinitis and sinusitis is 61.73%(313/507);the rhinopolypus is 22.87%(116/507);the cyst is 4.93%(25/507);the fungal sinusitis is 1.38%(7/507); the malignant tumor is 0.79%(4/507); the deviation of nasal septum is 65.66%(333/507);the Onodi cellulae is 29.19%(148/507);the Haller cellulae is 12.42%(63/507).The rate of hypoplasia of sphenoidal sinus is 3.94%(20/507); the rate of hypoplasia of maxillary sinus is 1.97%(10/507).Conclusion:The diagnosis of disorders of nose and paranasal sinuses can be made depending on coronary CT findings and CT coronary focused scan is possible to show the CT feature of anatomic variations of nose and paranasal sinuses.
