摘　　要：目的 :探讨CT仿真内镜和后处理技术应用于中耳听骨链病变的价值及局限性。方法 :95例、10 8耳采用不同方式扫描与重建。结果 :95例、10 8耳中双耳发病 2 6例 ,95例中 10 2耳患有中耳乳突炎。其中听骨链畸形 15例 ,胆脂瘤 6 9例 ,骨疡型中耳乳突炎 2 1例 ,外耳道癌侵犯中耳 3例。结论 :CT仿真内镜和其它后处理方法能清楚显示听骨链和锤、砧骨的大小、形态及相互之间的关系 ,也能较好地显示听骨链及锤、砧骨的解剖结构畸形、变异 ,对诊断中耳胆脂瘤及中耳乳突炎等疾病有重要价值 。Objective: To investigate the application and limitation of CT virtual endoscope in the diagnosis of middle ear diseases.Method:95 cases with 108 ears were selected to underline CT scan and reconstruction of images. Results:26 cases had two-ear diseases;102 ears in 95 cases had otitis mastoidea,15 cases with malformation of ossicular chain,69 with cholesteatoma,21 with bone-ulcer type otitis mastoidea,3 with middle ear invasion of cancer of external auditory canal.Conclusion:CTVE and other post-managements could clearly show the shape, size and their internection of ossicles chain,hammer and stapes.It is valuable to diagnose the cholesteatoma and otitis media by CTVE,which has opened a new way for the examination of middle ear diseases and the preparation of imaging materials before operation.
