To report a case of a patient with otosclerosis of the incus.
A 61-year-old woman with a progressive hearing loss on her left ear and a computed tomographic scan of the temporal bone revealing an expansible lesion of the incus.
The ossicle was removed by using a transtympanomastoid approach; the ossicular chain was reconstructed using a titanium partial ossicular replacement prosthesis.
The diagnosis of the disease was obtained by means of histopathologic examination of the specimen.
The patient obtained a good postoperative hearing result. The histopathologic examination of the specimen documented an otosclerosis of the incus.
Otosclerotic involvement of the middle ear ossicles, apart from footplate, was very rarely mentioned. Most subjects were incidentally diagnosed postmortem by means of examination of specimens from temporal bone collections. The diagnosis and treatment of a patient with otosclerosis of the incus is exceptional; however, otosclerosis should be considered in the differential diagnosis of expansible lesions of the ossicles.
报告一例砧骨耳硬化症患者。
一名61岁女性，左耳渐进性听力丧失，颞骨计算机断层扫描显示砧骨有可扩张性病变。
采用经鼓室乳突入路切除听小骨；使用钛质部分听骨置换假体重建听骨链。
通过对标本进行组织病理学检查确诊疾病。
患者术后听力恢复良好。标本的组织病理学检查证实为砧骨耳硬化症。
中耳听小骨除镫骨底板外发生耳硬化症的情况很少被提及。大多数病例是在尸检时通过检查颞骨标本偶然诊断出来的。砧骨耳硬化症患者的诊断和治疗较为罕见；然而，在鉴别诊断听小骨可扩张性病变时应考虑耳硬化症。
