目的:探讨CT对慢性副鼻窦炎的诊断价值,分析各副鼻窦慢性炎症与窦口鼻道区病变的关系。方法:对近两年收集的101例患者的CT资料就副鼻窦炎症的轻重程度、位置分布及范围大小进行分类分析。结果:全鼻窦病变17例(16.8％),单纯上颌窦慢性炎症33例(32.7％),上颌窦+额窦+筛窦前组18例(17.9％)、后组筛窦+蝶窦13例(12.8％),单纯筛窦炎症15例(14.9％),其他改变5例(4.9％)。 结论:鼻旁窦窦口鼻道区的解剖对鼻窦炎的发生、发展和治疗有密切关系,是炎症的易发部位,亦是使各副鼻窦产生慢性炎症的初发部位。
Objective: To investigate the diagnostic value of CT in chronic sinusitis and to analyze the relationship between chronic inflammation of paranasal sinuses and lesions in the nasal passages of the ostia. Methods: The CT data of 101 patients collected in the past two years were analyzed in terms of severity, location and size of paranasal sinusitis. Results: 17 cases (16.8%) had sinusitis, 33 cases (32.7%) had simple chronic inflammation of maxillary sinus, 18 cases (17.9%) had maxillary sinus + frontal sinus + ethmoid sinus, 13 cases posterior ethmoid + sphenoid sinus (12.8%), simple ethmoid inflammation in 15 cases (14.9%), other changes in 5 cases (4.9%). CONCLUSION: Anatomy of the sinus palatal nasal region is closely related to the occurrence, development and treatment of sinusitis. It is a predilection site of inflammation and a primary site of chronic inflammation of paranasal sinuses.
