Abstract：
Conductive hearing loss with normal otoscopic findings has many differential diagnosis, but the diagnosis of otosclerosis is retrospective after exploratory tympanotomy. Congenital ossicular anomalies in isolation are rare and often have a delayed diagnosis, particularly if unilateral. Herein we present a rare case of stapes abnormality that was encountered as a surprise during exploratory tympanotomy in a case of conductive hearing loss mimicking clinical otosclerosis and was managed accordingly.
摘要：
具有正常耳镜检查结果的传导性听力损失有许多鉴别诊断，但是耳硬化症的诊断是在鼓室探查切开术后的回顾性诊断。孤立的先天性听骨异常很少见，通常会延迟诊断，尤其是单方面的。在此，我们介绍了一种罕见的stap骨异常病例，该病例在探索性鼓膜切开术中遇到了类似于临床耳硬化症的传导性听力损失，并得到了相应的处理。
