颅脑常规CT扫描诊断鼻窦病变的评价

Routine Brain CT Evalution of Disease Accessory Sinus

目的:探讨常规颅脑CT诊断副鼻窦病变的价值。方法:随机抽取2000年至2004年间1000份颅脑CT片(软组织窗和骨窗),观察和分析鼻窦的显示情况及病变的诊断,并与原诊断对照。结果:筛窦、蝶窦、额窦、上颌窦显示率分别为100%、100%、97.8%、18.5%。鼻窦病变情况:总阳性率22.9%,其中炎症83%,肿瘤7.4%,囊肿瘤1.3%,外伤9.2%。鼻窦漏诊率:总漏诊率62.0%,炎症占全部漏诊者的76.6%,颅脑CT报正常者占全部漏诊者的60.0%。结论:常规颅脑CT对鼻窦病变的诊断有利用价值。

Objective To discuss the diagnostic valul of routine brain CT scan for diseases of accessory sinus. Methods To review images（soft tissue wind and bone wind） of 1 000 cases brain CT during the year of 2000 to 2004,The showing of accessory sinus and diagnosis was analysed and compared with prior diagnosis. Results showing accessory sinus： Among them,ethmoid sinus,sphenoid sinus,frontal sinus and maxillary sinus were 100%, 100% ,97.8% and 18.5%, showing rate respectively. Incidence ： There was total 22.9 % incidence, among them, sinusitis, neoplasm, cyst and trau ma were 83% ,7.4% ,1.3% and 9.2% respectively. Leaky diagnosis：There was total 62.0% leaky rate. among them, sinusitis were 76.6% ,diagnosed normal were 60.0%. Conclusion Routine brain CT scan is diagnostic value for disease accessorry smus.
