为探讨颞骨高分辨率ＣＴ在慢性化脓性中耳炎诊断中的价值，对７９例（９７耳）慢性化脓性中耳炎患者的ＣＴ扫描和手术中颞骨所见进行对比分析。认为高分辨率ＣＴ不仅能将胆脂瘤精确定位，而且还能显示周围骨质的破坏程度，能早期预测颅内并发症的发展，确定不典型的广泛破坏性病变。ＣＴ扫描较Ｘ线摄片具有明显的优越性，但作出诊断还应密切结合临床。
To explore the value of temporal bone high resolution CT in the diagnosis of chronic suppurative otitis media, the CT scan of 79 patients (97 ears) with chronic suppurative otitis media was compared with the temporal bone seen during surgery. That high-resolution CT can not only accurately locate the cholesteatoma, but also shows the extent of destruction of the surrounding bone, can predict the development of intracranial complications in the early stage, to identify atypical and extensively devastating lesions. CT scan than X-ray has obvious advantages, but the diagnosis should be closely combined with clinical.
