Results from 80 pediatric subjects with 12 months of experience wearing the Nucleus multichannel cochlear implant are presented. The data suggest that children demonstrate statistically and clinically significant benefit across a broad spectrum of abilities with the implant. Significant postoperative improvement was demonstrated by 66 percent (51 of 77), 63 percent (45 of 72), and 46 percent (27 of 59) of subjects tested on suprasegmental (prosodic), closed-set and open-set tests, respectively. Forty-nine percent of subjects tested improved when lipreading was combined with sound from the implant, compared with lipreading alone. Children who were deaf at an early age or who had longer duration deafness tended to demonstrate poorer performance on the more difficult perceptual tasks after 12 months of implant experience. However, preliminary evidence suggests that continued improvements by congenital and prelinguistic subjects over longer periods of time may reduce performance differences between subjects with early and later onset deafness.
本文呈现了80名佩戴Nucleus多通道人工耳蜗12个月的儿科受试者的结果。数据表明，儿童在使用该人工耳蜗后，在广泛的能力范围内展现出了具有统计学意义和临床意义的益处。在超音段（韵律）、闭集和开集测试中，分别有66%（77名中的51名）、63%（72名中的45名）和46%（59名中的27名）的受试儿童术后有显著改善。与仅使用唇读相比，49%的受试儿童在将唇读与人工耳蜗声音相结合时表现有所改善。在植入人工耳蜗12个月后，早年失聪或失聪时间较长的儿童在较困难的感知任务上往往表现较差。然而，初步证据表明，先天性和语言前受试者在更长时间内的持续改善可能会缩小早发性和迟发性耳聋受试者之间的表现差异。
