摘要
目的 :探讨具有典型慢性鼻窦炎症状患者鼻窦 CT扫描阴性的原因。方法 :分析 8例 CT扫描阴性的鼻窦炎患者的临床资料。结果 :8例均在功能性鼻内窥镜手术中发现鼻窦内粘膜肿胀、息肉样变或小息肉形成。结论 :具有典型鼻窦炎症状而鼻窦 CT扫描出现阴性结果的原因为 :1鼻窦 CT扫描仅能提供静态的影像学结果 ;2可能与部分容积效应有关 ;3与断层的部位和 CT分辨率有关 ;4可能与慢性鼻窦炎的病理学改变和分型有关。
Objective:To explore the reason why the CT manifestation of the patients with chronic nasosinusitis is negative.Method:To analyze the clinical and CT manifestation of the patients with chronic sinusitis having a negative CT manifestation.Result:Pathological changes were found in all 8 patients during the course of endoscopic sinus surgery, such as pus storing in the sinus cavity, mucous swelling polypoidly, small polyps formation and so on. Conclusion:The reasons that the patients with chronic sinusitis having a negative CT manifestation are, ①CT scan can only give a static one off image, ② partial volume effect,③ maybe result from the location of CT scan and the resolving power of tomograph,④ maybe attribute to the pathological classify of chronic sinusitis.
