The aim of this article is to give readers a general overview of the concepts involved in the latest generation of implantable hearing aids. A section on ear biomechanics has also been included to familiarize readers with the basic concepts involved. These devices have been developed over the last 20 years, driven by problems with conventional hearing aids and by advances in the understanding of middle-ear mechanics. The use of technology borrowed from cochlear implants has enabled the first generation of fully implantable aids to be trialled. The author examines the theoretical advantages and disadvantages of implantable hearing aids over conventional aids and then reviews the technology and clinical results of a range of devices that have been trialled.
本文旨在让读者对最新一代可植入式助听器所涉及的概念有一个总体的了解。还纳入了一个关于耳生物力学的章节，以使读者熟悉其中涉及的基本概念。在过去20年里，由于传统助听器存在的问题以及对中耳力学认识的进步，这些装置得以发展。借鉴人工耳蜗的技术使得第一代完全可植入式助听器得以进行试验。作者研究了可植入式助听器相对于传统助听器在理论上的优缺点，然后回顾了一系列已进行试验的装置的技术和临床结果。
