现在有许多单侧人工耳蜗植入者在非植入耳中有可用的剩余听力。为了避免听力剥夺并提供双耳听力，可以在该耳朵上安装助听器或第二个耳蜗植入物。本文讨论双耳/双耳配戴(对侧耳植入人工耳蜗加助听器)或双耳植入能否获得更好的双耳听力的问题。在本文的第一部分，研究了提供双耳听力的基本原理。第二部分对双耳/双峰拟合法和双侧植入的相对疗效进行了文献综述。大多数关于比较双侧刺激和单侧植入模式的研究平均而言在某些测试条件下报告了一些双耳益处，但发现一些人受益，而另一些人则没有。在双耳/双峰匹配和双侧植入之间没有对照比较，也没有证据支持一种模式比另一种模式更有效。在文章的第三部分，报告了两个成年人的交叉试验，他们接受了双耳/双峰匹配，随后接受了第二次种植。在他们接受第二次植入后6个月和12个月的研究结果表明，双耳功能随着时间的推移而发展，受益的程度取决于对个人能力的评估。在文章的第四部分和最后部分，讨论了与双耳/双峰拟合候选有关的临床问题和双峰拟合的策略，并对未来的研究提出了建议。
There are now many recipients of unilateral cochlear implants who have usable residual hearing in the non-implanted ear. To avoid auditory deprivation and to provide binaural hearing, a hearing aid or a second cochlear implant can be fitted to that ear. This article addresses the question of whether better binaural hearing can be achieved with binaural/bimodal fitting (combining a cochlear implant and a hearing aid in opposite ears) or bilateral implantation. In the first part of this article, the rationale for providing binaural hearing is examined. In the second part, the literature on the relative efficacy of binaural/bimodal fitting and bilateral implantation is reviewed. Most studies on comparing either mode of bilateral stimulation with unilateral implantation reported some binaural benefits in some test conditions on average but revealed that some individuals benefited, whereas others did not. There were no controlled comparisons between binaural/bimodal fitting and bilateral implantation and no evidence to support the efficacy of one mode over the other. In the third part of the article, a crossover trial of two adults who had binaural/bimodal fitting and who subsequently received a second implant is reported. The findings at 6 and 12 months after they received their second implant indicated that binaural function developed over time, and the extent of benefit depended on which abilities were assessed for the individual. In the fourth and final parts of the article, clinical issues relating to candidacy for binaural/ bimodal fitting and strategies for bimodal fitting are discussed with implications for future research.
