Abstract

We report a case of conductive hearing loss caused by isolated congenital stapedial suprastructure fixation with normal footplate mobility. A 60-year-old woman visited the clinic for right-sided mixed hearing loss. Exploratory tympanotomy revealed a bony synostosis between the stapedial suprastructure and promontory, while all the ossicles were present and normally shaped. As the bony synostosis was separated, the stapes became mobile. This is the first report in the medical literature of this congenital ear anomaly. This case also illustrates that stapedial fixation can occur in the suprastructure as well as in the footplate; thus, one must be mindful of this when performing exploratory tympanotomy for stapes fixation.
孤立性先天性镫骨上结构固定1例
我们报告一例传导性听力损失是由孤立的先天性镫骨上结构固定引起的。一名60岁妇女因右侧混合性听力损失就诊。探索性鼓室切开术显示镫骨上结构和海岬之间有骨结合,而所有小骨均存在且形状正常。随着骨性结膜的分离,镫骨开始活动。这是医学文献中首次报道这种先天性耳畸形。该病例还表明,镫骨固定既可发生在足跖,也可发生在上部结构;因此,在进行探索性鼓室切开术进行镫骨固定时,必须注意这一点。
