摘要
目的：探讨中耳软组织病变ＣＴ特征、诊断及鉴别诊断。材料与方法：临床拟诊中耳疾病４５例患者进行了高分辨率ＣＴ扫描。手术或／和病理证实２８例３２耳。结果：胆脂瘤病变大多呈团块状（７６．９２％，１０／１３），常伴有明显的听骨破坏（１００％，１３／１３）和盾板骨质破坏（８４．６２％，１１／１３）；而肉芽肿病灶大多呈片状、条索状或网状（９１．６７％，１１／１２），听骨破坏相对轻（５０％，６／１２），少有盾板骨质破坏（１６．６７％，２／１２）。结论：根据中耳腔内软组织的形态、骨破坏情况，大多数病例能作出诊断和鉴别诊断。
To study the CT features,diagnosis and differential diagnosis of middle ear diseases.Materials and Methods:45 patients with midder diseases proved by surgeon and/or pathology in 28 cases(32 ears) were studied with high resolution CT,Results:The lesion of cholesteatoma was mass-shaped mostly(79.92%,10/13) accompanied with obvious ossicular destruction (100%,13/13) and secutum erosion(84.62%.11/13).However,the lesion of granuloma were usually patch-like,streak-like or net-like(91.67%,11/12) with slight ossicular destruction(50%,6/12) and seldom secutum erosion(16.67%,2/12).Conclusion:Based on above mentioned CT features,CT can predict the diagnosis and differentiation between cholesteatoma and granuloma in most patients.
