Patients with 'far-advanced' or 'very far-advanced' otosclerosis have a profound bilateral hearing loss, with apparently no cochlear reserve measured by standard clinical audiometers. These patients have no benefit from a powerful hearing aid, have severe feedback problems and the cochlear implant may be the only solution. A total of 12 stapedotomies were performed in 8 patients with far-advanced or very far-advanced otosclerosis, with satisfactory results, improved air conduction thresholds and improved cochlear function and speech discrimination. Stapedotomy is a useful procedure for patients with far-advanced otosclerosis which improves patient's hearing to levels where they can benefit from less powerful hearing aids with fewer feedback problems, compared to no measurable preoperative hearing aid benefit. It also spares those patients being submitted to cochlear implantation.
患有“极重度”或“极其极重度”耳硬化症的患者双耳听力严重丧失，使用标准临床听力计测量时显然没有耳蜗储备。这些患者无法从功能强大的助听器中获益，存在严重的反馈问题，而人工耳蜗植入可能是唯一的解决办法。对8例极重度或极其极重度耳硬化症患者共进行了12次镫骨切除术，结果令人满意，气导阈值改善，耳蜗功能和言语辨别能力提高。与术前使用助听器无明显获益相比，镫骨切除术对极重度耳硬化症患者是一种有用的手术，可将患者听力提高到能从功能较弱、反馈问题较少的助听器中获益的水平。它还使这些患者无需接受人工耳蜗植入。
