The objective of the present work was to enhance the effectiveness of diagnostics of cholesteatoma of the external and middle ear in the children. The study included 66 patients presenting with chronic suppurative otitis media and one child having cholesteatoma of the external auditory meatus. All the patients were examined with the use of otoendoscopy and CT of the temporal bones. It was shown that the frequent occurrence of acute suppurative otitis media, exudative suppurative otitis media, and adhesive otitis media is the risk factor of the development of cholesteatoma of the external and middle ear in the children. The following CT features of cholesteatoma of the external ear were revealed: the sclerotic or mixed type of the mastoid process, the presence of pathological contents in the epitympanic space, homogeneous character of pathological contents in the antrum, widened aditus, caries of antrum walls, the presence of soft tissues around the auditory ossicles, destruction of the long process of the anval bone, and a soft-tissue structure in the external auditory meatus.
本研究的目的是提高儿童外耳道及中耳胆脂瘤的诊断效率。该研究纳入了66例慢性化脓性中耳炎患者及1例外耳道胆脂瘤患儿。所有患者均接受了耳内镜检查及颞骨CT检查。结果显示，急性化脓性中耳炎、渗出性化脓性中耳炎及粘连性中耳炎的频繁发作是儿童外耳道及中耳胆脂瘤发生的危险因素。外耳道胆脂瘤的CT表现如下：乳突硬化型或混合型、上鼓室存在病理性内容物、鼓窦内病理性内容物均匀、鼓窦入口增宽、鼓窦壁龋坏、听小骨周围存在软组织、砧骨长突破坏及外耳道内软组织结构。
