Inflammation of the middle ear cleft is a disease of great interest from both clinical and radiologic points of view. The attic floor (tympanic diaphragm), the tympanic isthmus, and the aditus ad antrum play important roles in inflammatory processes of the middle ear cleft. The anatomy of the temporal bone at this level was examined by studying microdissections of 250 fresh temporal bones and reviewing over 1,000 high-resolution computed tomography (CT) scans of the temporal bones. The pertinent anatomy is described, and the role of the tympanic diaphragm and isthmus in determining the degree to which middle ear disease may progress is stressed. The appearances on CT scans of chronic otomastoiditis, tympanosclerosis, cholesterol granuloma, attic retraction pocket, and acquired cholesteatoma are reviewed and illustrated.
从中耳裂炎症的临床和放射学角度来看，它都是一种备受关注的疾病。上鼓室底部（鼓膜）、鼓室峡部和鼓窦入口在中耳裂的炎症过程中发挥着重要作用。通过对250块新鲜颞骨进行显微解剖研究，并回顾1000多例颞骨高分辨率计算机断层扫描（CT），对该层面的颞骨解剖结构进行了研究。描述了相关解剖结构，并强调了鼓膜和峡部在确定中耳疾病可能进展程度方面的作用。对慢性中耳乳突炎、鼓室硬化症、胆固醇肉芽肿、上鼓室回缩袋和后天性胆脂瘤的CT扫描表现进行了回顾并举例说明。
