Abstract

Older adults who qualify for cochlear implantation demonstrate significant improvements in speech recognition and quality of life with cochlear implant use. Cochlear implantation is a safe and effective procedure for patients with hearing loss, with some additional medical considerations specific to older adult patients. The indications for cochlear implantation have expanded from cases of bilateral severe-to-profound hearing loss to cases of normal-to-moderate low-frequency hearing sensitivity and severe-to-profound high-frequency hearing loss. The expansion of indications for cochlear implantation was prompted by evidence of low-frequency hearing preservation due to modified electrode array designs and surgical techniques, and significantly improved performance when listening with the combination of acoustic and electric stimulation (EAS) in the same ear. Older adults who underwent cochlear implantation as part of clinical trials investigating the effectiveness of EAS have been shown to experience significantly improved speech recognition and quality of life as compared to preoperative performance with conventional hearing aids.

老年人人工耳蜗植入术的有效性和扩展适应症

符合人工耳蜗植入条件的老年人使用人工耳蜗后，语音识别和生活质量显著提高。人工耳蜗植入术对听力损失患者来说是一种安全有效的手术，还有一些针对老年患者的额外医疗考虑。人工耳蜗植入的适应症已从双侧重度至重度听力损失扩展到正常至中度低频听力敏感性和重度至重度高频听力损失。人工耳蜗植入适应症的扩大是因为有证据表明，由于改进了电极阵列设计和手术技术，低频听力得到了保护，并且在同一只耳朵中结合声学和电刺激（EAS）听力时，性能显著提高。作为研究EAS有效性的临床试验的一部分，接受人工耳蜗植入的老年人与传统助听器的术前表现相比，语音识别和生活质量显著提高。REviEw艺术
