CTVE, SSD of ossicular chain and the oblique reconstruction of stapes of normal ears were compared with anatomy and coronal and axial CT film, and that of ill ears were compared with operation and coronal and axial CT film.

33例66耳行颞骨GE Lightspeed 64排螺旋CT容积扫描，正常组35耳，病变组31耳，用GE Advantage工作站行中耳CTVE、听骨链SSD及镫骨前后脚的斜轴位重建与冠、轴位CT及手术所见进行对照。

Result: may clearly demonstrate using mip to the auditory bone chain that, to the malleus, the anvil, the stirrup bone and firstmay achieve 100% demonstration,ledger wall partial demonstrations.

结果：运用mip对听骨链可以清楚显示，对锤骨、砧骨、镫骨头及前后角可达到100%显示，镫骨底板部分显示。

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.

胆脂瘤型中耳炎SCT-3DI示：鼓室、鼓窦内软组织影和骨质破坏，听骨链移位和破坏，严重者破坏鼓室盖、面神经管、外半规管和乙状窦板等，与手术中所见基本相符。
