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%～100%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(20%)。结论高分辨率CT扫描对慢性化脓性中耳炎合并胆脂瘤患者有较高的应用价值。

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.
