目的：本研究的目的是探讨人工耳蜗植入后汉语儿童开放集合词知觉的纵向表现。方法：前瞻性队列研究。105名植入CI的语前聋儿童参加了这项研究。采用标准汉语版的单音节词邻近测验（LNT）和多音节词邻近测验（MLNT）作为开放集合词知觉评价工具。结果：（1）先天性聋儿童CI刺激后6、12、24、36、48、60、72和84个月的言语知觉成绩随时间的延长而显著提高。(2)最快的改善发生在初始激活后的前36个月，然后改善放缓，最终在初始激活后72个月达到81.7%正确的峰值评分。(3)早期植入的儿童表现出更好的纵向性能。(4)词汇因素在每次评估中的影响是一致的。对于词汇难词，如单音节难词，有很大的改善空间，即使在长期使用CI。结论：（1）CI持续提供显着的好处，在词的知觉严重/深度感音神经性听力损失的儿童。(2)植入年龄和普通话词汇因素对纵向操作有显著影响。(C)2015爱思唯尔爱尔兰有限公司版权所有。
Objective: The objective of the present study was to investigate the longitudinal performance on open-set word perception in Mandarin children with cochlear implants (CIs).Methods: Prospective cohort study. One hundred and five prelingually deaf children implanted with CIs participated in the study. The Standard-Chinese Version of Monosyllabic Lexical Neighborhood Test (LNT) and Multisyllabic Lexical Neighborhood Test (MLNT) were used as open-set word perception evaluation tools. Evaluations were administrated at 6, 12, 24, 36, 48, 60, 72, and 84 months post CI stimulation, respectively.Results: (1) Spoken word perception performance of congenitally deaf children with CIs improved significantly over time. (2) The fastest improvement occurred in the first 36 months after initial activation, then the improvement slowed down and the final peak score of 81.7% correct was achieved at 72 months after initial activation. (3) Early implanted children exhibited better longitudinal performance. (4) Lexical factors affected consistently in each evaluation session. For lexically harder words, such as monosyllabic hard words, there was substantial room for improvement even after long-term use of CI.Conclusions: (1) CI continuously provided significant benefits in word perception to children with severe/profound sensorineural hearing loss. (2) Age at implantation and Mandarin lexical factor affected longitudinal performance significantly. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
