应用颅脑常规CT扫描进行鼻窦病变诊断分析

The application value of conventional CT scanning in diagnosing the paranasal sinus

目的分析并总结常规颅脑CT诊断副鼻窦病变情况及其应用价值。方法随机性抽取2006年12月至2010年12月期间的500张常规颅脑CT片,与原诊断进行对照,并通过对鼻窦的显示结果与疾病的诊断进行综合分析。结果本组全部病例筛窦与蝶窦的显示率均为100%,显示分别位于1～3层面和1～2层面;额窦部位的显示率为97.8%,显示位于2～5层面;上颌窦显示率仅仅为18.6%,显示位于1～5层面。鼻窦病变的总阳性率为22.9%,其中炎症、肿瘤、囊肿瘤与外伤所占百分比分别为83.0%、7.4%、1.2%和9.2%。鼻窦总漏诊率为62.0%,炎症占所有漏诊病例的76.6%,颅脑CT报告正常患者占漏诊病例的60.0%。结论常规颅脑CT对于诊断鼻窦病变具有重要的参考价值,应引起影像医师的高度重视。

Objective To analyz the lesions situation of paranasol sinus by conventional CT scanning and it＇s application value.Methods A random extraction from December 2006 to December 2010 during the 500 routine brain CT slices were compared with the original diagnosis,and display the results through the sinuses and disease diagnosis were analyzed.Results All patients showed ethmoid and sphenoid sinus rate was 100%,respectively,in 1 to 3 show levels and levels 1 and 2.Frontal parts of the display rate was 97.8%,showing levels at 2 to 5.Maxillary sinus rate was only 18.6% displayed,showing at 1 to 5 level.The positive sinus lesions was 22.9%,and inflammation,cancer,cystic tumor with the percentage of trauma were 83.0%,7.4%,1.2% and 9.2%.Missed diagnosis rate was 62.0% of total sinus inflammation accounted for 76.6% of all cases of missed diagnosis,patients with normal brain CT reports accounted for 60.0% of cases of missed diagnosis.Conclusion Routine brain CT in the diagnosis of sinus disease has important reference value,which should be added,MD＇s attention.
