This paper reviewed the literature on the trajectories and the factors significantly affecting post-implantation speech perception development in Mandarin-speaking children with cochlear implants (CIs).
A systematic literature search of textbooks and peer-reviewed published journal articles in online bibliographic databases was conducted.
PubMed, Scopus and Wiley online library were searched for eligible studies based on predefined inclusion and exclusion criteria.
A total of 14 journal articles were selected for this review. A number of consistent results were found. That is, children with CIs, as a group, exhibited steep improvement in early speech perception, from exhibiting few prelingual auditory behaviours before implantation to identifying sentences in noise after one year of CI use. After one to three years of CI use, children are expected to identify tones above chance and recognition of words in noise. In addition, early age at implantation, longer duration of CI use and higher maternal education level contributed to greater improvements in speech perception.
Findings from this review will contribute to the establishment of appropriate short-term developmental goals for Mandarin-speaking children with CIs in mainland China and clinicians could use them to determine whether children have made appropriate progress with CIs.
本文回顾了有关汉语人工耳蜗植入儿童植入后言语感知发展轨迹及显著影响因素的文献。
在在线书目数据库中对教科书和同行评审发表的期刊文章进行系统的文献检索。
根据预先定义的纳入和排除标准，在PubMed、Scopus和Wiley在线图书馆中搜索符合条件的研究。
本综述共筛选出14篇期刊文章。发现了一些一致的结果。即人工耳蜗植入儿童作为一个群体，在早期言语感知方面有显著改善，从植入前几乎没有语前听觉行为到使用人工耳蜗一年后能在噪声中识别句子。使用人工耳蜗一到三年后，儿童有望能在高于随机水平上识别声调并在噪声中识别单词。此外，植入时年龄较小、人工耳蜗使用时间较长以及母亲教育水平较高有助于言语感知有更大改善。
本综述的结果将有助于为中国大陆汉语人工耳蜗植入儿童制定适当的短期发展目标，临床医生可利用这些目标来确定儿童使用人工耳蜗后是否取得了适当的进展。
