Erosions of the ossicular chain that occurred as a complication of noncholesteatomatous chronic otitis media were studied with computed tomography (CT) in 55 patients. The incus (particularly the long and lenticular processes) was the ossicle most commonly involved (50 cases). Coronal and axial CT sections were complementary in the diagnosis of these erosions. Fibrous replacement of the incudostapedial articulation was diagnosed in four cases on axial CT scans when an unusually wide joint was present.
对55例因非胆脂瘤性慢性中耳炎并发症导致听骨链侵蚀的患者进行了计算机断层扫描（CT）研究。砧骨（尤其是长突和豆状突）是最常受累的听小骨（50例）。冠状位和轴位CT扫描在这些侵蚀的诊断中互为补充。当轴向CT扫描显示关节异常增宽时，在4例中诊断出砧镫关节的纤维性替代。
