The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and lack of connection between the stapes superstructure and footplate. The footplate was fixed. Stapedotomy and stapes prosthesis insertion resulted in closure of the air-bone gap by 50 dB. A review of world literature was performed using MedLine. Middle ear ossicular discontinuity can result in significant conductive hearing loss. This can be managed effectively with surgery to help restore hearing. However, some patients may not be suitable or decline surgical intervention and can be managed safely conservatively.
本研究的目的是提高对罕见表现、诊断困难以及传导性听力损失和听骨异常管理的认识。我们报告了一例13岁女性，该患者自述左侧听力进行性下降，最初高分辨率计算机断层扫描报告为正常。 exploratory tympanotomy显示镫骨肌腱缺如，镫骨上部结构与脚板之间缺乏连接。脚板固定。镫骨切除术和镫骨假体植入使气骨导差缩小了50dB。使用MedLine对世界文献进行了综述。中耳听骨连续性中断可导致显著的传导性听力损失。这可以通过手术有效治疗以帮助恢复听力。然而，一些患者可能不适合或拒绝手术干预，可以安全地进行保守治疗。 （注：原文中“exploratory tympanotomy”可能有误，推测可能是“exploratory tympanoplasty”，意为“探查性鼓室成形术” ）
