To study the use of spiral-CT three-dimensional reconstruction in chronic otitis media.
The images of spiral-CT three-dimensional reconstruction (SCT-3DI) and surgical findings in 22 ears with chronic otitis media were compared.
The lesions showed in SCT-3DI were in accord with those seen in the operation. There were no bone erosion in the 3 ears with simple type otitis media, and the 19 ears with cholesteatoma showed: abnormal soft-tissue and bony erosion in the tympanic cavity and antrum; dislocation and disruption of the ossicular chain; and showed disruption of sigmoid sinus plate, tegmen tympani, semicircular canal and facial nerve canal in severe cases.
The spiral-CT has more superiority over traditional-CT in diagnosis of lesions in chronic otitis media before operation.
研究螺旋CT三维重建在慢性中耳炎中的应用。
对22例慢性中耳炎患者的螺旋CT三维重建（SCT - 3DI）图像与手术所见进行对比。
SCT - 3DI显示的病变与手术所见相符。3例单纯型中耳炎未见骨质侵蚀，19例胆脂瘤型中耳炎表现为：鼓室和鼓窦内软组织异常及骨质侵蚀；听骨链脱位和中断；严重者可见乙状窦板、鼓室盖、半规管和面神经管中断。
螺旋CT在慢性中耳炎术前病变诊断方面较传统CT具有更多优势。
