在美国，听力损失影响着大约3000万人。据估计，只有大约20%的听力损失严重到需要放大的人实际上寻求帮助进行放大。多年来，人们对中耳植入物产生了浓厚的兴趣，以帮助那些不符合传统助听器、无法从传统助听器中获得显著好处或不适合植入人工耳蜗的患者。从20世纪30年代的最初研究开始，这项技术在过去几年里有了很大的发展，在开发植入式中耳听力装置时采用了广泛的设备和机制。目前，这些装置通常有两大类：使用压电或电磁系统的部分或全部植入。作者介绍了主要的植入式中耳装置的最新概述。尽管目前的设备在很大程度上还处于初级阶段，但随着有希望的研究显示良好的结果，中耳植入的适应症正在不断演变。完全可植入的设备为用户提供了从使用传统放大的社会和实际困难中解脱出来的自由。
Hearing loss affects approximately 30 million people in the United States. It has been estimated that only approximately 20% of people with hearing loss significant enough to warrant amplification actually seek assistance for amplification. A significant interest in middle ear implants has emerged over the years to facilitate patients who are noncompliant with conventional hearing aides, do not receive significant benefit from conventional aides, or are not candidates for cochlear implants. From the initial studies in the 1930s, the technology has greatly evolved over the years with a wide array of devices and mechanisms employed in the development of implantable middle ear hearing devices. Currently, these devices are generally available in two broad categories: partially or totally implantable using either piezoelectric or electromagnetic systems. The authors present an up-to-date overview of the major implantable middle ear devices. Although the current devices are largely in their infancy, indications for middle ear implants are ever evolving as promising studies show good results. The totally implantable devices provide the user freedom from the social and practical difficulties of using conventional amplification.
