The aim of this study is to show the importance of computed tomography scanning (CT) and magnetic resonance imaging (MRI) in ancient radical cavities and to determinate the risk factors of an invasive cholesteatoma recurrency.
We present 4 cases of medial invasion in the petrous bone of a cholesteatoma without specific symptomatology which appeared many years after undergoing radical mastoidectomy for an acquired cholesteatoma.
The analysis of this series allowed to put in evidence the factors of suspicion of an underlying cholesteatoma. They are: the age, an aural discharge, numerous surgical interventions, immunodeficiency, cholesteatoma in childhood and antecedent of facial nerve palsy. This trial emphasizes the importance of imaging (CT and MRI) in front of an ancient radical cavity which presents one or some of these factors in order to eliminate a recurrence of an invasive cholesteatoma. Let us note that the demand of the patients is sometimes aesthetic or functional.
本研究旨在表明计算机断层扫描（CT）和磁共振成像（MRI）在陈旧性根治性中耳腔中的重要性，并确定侵袭性胆脂瘤复发的危险因素。
我们呈现了4例胆脂瘤侵犯岩骨内侧的病例，这些病例在因后天性胆脂瘤接受根治性乳突切除术后多年出现，且无特定症状。
对该系列病例的分析揭示了胆脂瘤潜在病变的可疑因素。这些因素包括：年龄、耳漏、多次手术干预、免疫缺陷、儿童期胆脂瘤以及面神经麻痹病史。本研究强调了在出现上述一个或多个因素的陈旧性根治性中耳腔中进行影像学检查（CT和MRI）以排除侵袭性胆脂瘤复发的重要性。需要注意的是，患者的需求有时是出于美观或功能方面的考虑。
