摘要: 目的 探讨中耳胆脂瘤的高分辨率CT(HRCT)盾板表现, 评价盾板破坏在中耳胆脂瘤的诊断价值。方法 选择经手术及术后病理确诊的中耳胆脂瘤患者38例(42耳)为研究对象, 分析其HRCT影像资料。结果 38例(42耳)中耳胆脂瘤患者中发生盾板破坏37耳, 盾板完整、鼓膜松弛部穿孔或紧张部穿孔4耳, 鼓膜完整1耳。结论 盾板破坏是诊断中耳胆脂瘤的特征性CT 征象, 诊断特异性强、敏感性差。部分中耳胆脂瘤患者, 颞骨CT盾板可表现为完整。

Abstract: Objective To evaluate erosion of scutum in the diagnosis of middle ear cholesteatoma by high-resolution CT scan(HRCT). Methods HRCT findings of 38 patients(in 42 ears)with middle ear cholesteatoma in our department were reviewed. The condition of the scutum was observed with CT scanning and surgical findings. Result There are 37 ears with erosion of scutum, 4 ears with marginal/central perforation and 1 ear with intact tympanic membrane. Conclusion Scutum erosion demonstrates an important role in the diagnosis of cholesteatoma of middle ear, however, this sign cannot be found in some patienas with cholesteatoma.

Key words: High-resolution CT, Scutum, Cholesteatoma
