【摘要】 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。更多还原

【Abstract】 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 trauma 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 sinus.更多还原
