目的 通过分析中耳胆脂瘤和中耳炎的 CT扫描影像改变 ,探讨胆脂瘤和中耳炎的 CT表现及诊断价值。方法 30例患者行颞骨岩部 CT扫描 ,将影像表现与手术所见进行对比。结果 鼓室胆脂瘤 93.8%显示 ,骨的侵蚀全部显示 ,砧骨、锤骨破坏 81.8%～ 10 0 %显示 ,鼓室胆脂瘤上鼓室宽度大于中耳炎上鼓室宽度 ,少数骨破坏有硬化边 ( 2 0 % )。结论 高分辨率
Objective The expression and diagnostic value of high resolution CT was discussed in chole steatoma、chronic suppurative otitis media through the retrospective analysis of the image changes.Methods Thirty cases of chronic suppurative otitis media were examined by high resolution CT in both axial and coronal section of temporal bone.CT findings were compared with operative findings.Results The display rate of cholesteatoma and bone erosion was 93.8% and 100% respectively.The display rate of destruction of malleus、longipedate and short crus of incus were 100%、81.8%、100% respectively.The width of epitympanic in cholesteatoma was wider than inflammation.There are a dense border of bone in few epitympanic cholesteatoma (20%).Conclusions High resolution CT has great value in the diagnosis of chronic suppuratioe otitis media,especially complicated with cholesteatoma.
