Malleus ankylosis is an uncommon finding during stapes surgery, which can result in functional failure if undetected during primary surgery. Its management can be difficult and different approaches and solutions have been described to date, most of which require interruption of the ossicular chain. We report the management of such condition through a transcanal endoscopic technique, with preservation of ossicular chain integrity.
The procedure was carried out in a patient affected by otosclerosis with persistent hearing loss after primary stapes surgery.
Surgical treatment of malleus head fixation through a totally endoscopic transcanal approach during revision stapes surgery.
Pure tone audiometry, speech audiometry.
The patient experienced a complete closure of the air-bone gap. No postoperative vertigo or sensorineural hearing loss were observed.
The present report describes the transcanal endoscopic management of malleus ankylosis during revision stapes surgery, which has not been previously reported in the literature. Pearls related to this approach and advantages in comparison to previously described approaches of the literature are discussed as well.
镫骨固定在镫骨手术中并不常见，如果在初次手术中未被发现，可能导致功能失败。迄今为止，已经描述了多种不同的处理方法，大多数方法都需要中断听骨链。我们报告了一种通过经耳道内镜技术来处理这种情况的方法，该技术可保持听骨链的完整性。
该程序是在一名患有耳硬化症的患者中进行的，该患者在初次镫骨手术后持续存在听力损失。
在翻修镫骨手术中通过完全经耳道内镜方法治疗镫骨头部固定。
纯音听阈测试，言语测听。
患者的气骨导差完全闭合。未观察到术后眩晕或感音神经性听力损失。
本报告描述了在翻修镫骨手术中通过经耳道内镜处理镫骨固定的方法，这在文献中尚未报道过。还讨论了与该方法相关的要点以及与文献中描述的先前方法相比的优势。
