摘要

BACKGROUND: This study aimed to determine 1) whether cochlear implants continued to benefit congenitally deaf childrens’ speech perception over a 2-year follow-up period, and 2) whether the age at implantation affected the development of speech perception by young deaf children.
METHODS: Twenty congenitally deaf children underwent Nucleus CI24M device implantation. Speech perception tests were conducted using the Mandarin Auditory Perception Test Battery (MAPTB) at 6-month intervals following implantation. The improvement with cochlear implants was assessed by monitoring the percentage of correct scores between 12 and 24 months after implantation. Regression analysis was used to correlate subject age at implantation with subject progress.
RESULTS: In the comparison of performance at 12 and 24 months post-implantation, subjects performed better at 24 than at 12 months in each sub-test, but differences were not statistically significant (p＞0.05). Progress (improvement in speech perception) at 12 and 24 months had a moderate, negative correlation with age at implantation in vowel, phrase and sentence tests (p＜0.05), but no correlation with age in spondee (p=0.09), consonant (p=0.21) and tone tests (p=0.27).
CONCLUSION: The results suggest that cochlear implants continue to benefit congenitally deaf children over a 2-year post-implantation period. Since age at implantation is negatively correlated with improved speech perception after implantation, congenitally affected children with profound deafness that is not helped by hearing aids should receive implants as early as possible.
