Abstract
OBJECTIVE: 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).
DESIGN: A systematic literature search of textbooks and peer-reviewed published journal articles in online bibliographic databases was conducted.
STUDY SAMPLE: PubMed, Scopus and Wiley online library were searched for eligible studies based on predefined inclusion and exclusion criteria.
RESULTS: 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.
CONCLUSIONS: 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.
