目的：分析继发性胆脂瘤的多排螺旋CT的表现，探讨其临床应用价值。方法收集我院58例患耳CT诊断或高度怀疑继发性胆脂瘤，所有病例采用轴位颞骨螺旋扫描，进行轴位、冠状位重建，必要时加脑窗重建。结果鼓室、乳突内软组织影（58患耳，100%），骨质破坏（58患耳，100%），自然根治腔（4患耳，7%），骨质硬化（48患耳，83%），Prussak间隙增宽（13患耳，22%）。结论多排螺旋CT扫描可以清晰显示耳部内部结构，在继发性胆脂瘤方面能为临床提供诊断依据、指导治疗方案及术后复查。

Objective Analyse the performance of multi-slice spiral CT in secondary cholesteatoma, and to ex-plore its clinical application value. Methods Collect the clinical data of 58 ears confirmed or highly suspected with secondary cholesteatoma in our hospital, and all cases with axial spiral scanning, the axial and coronal reconstruction, if necessary with the reconstructed brain window. Results Tympanic, mastoid within the shadow of soft tissue (58 ears,100%);destruction of bone (58 ears,100%); natural radical cavity (4 ears, 7%); osteosclerosis (48 ears,83%);broadening of Prussak gap (13 ears,22%). Conclusion Multi-slice spiral CT scan can clearly show the inner struc-ture of ear, which can provide the basis for diagnosis, therapy and postoperative clinical in the secondary cholesteatoma.
