Abstract:
Objective:To explore the early vowel perception development of pediatric cochlear implant(CI) of 1-3 years old. Method:A total of 123 children who had accepted cochlear implantation under 3 years old were analyzed retrospectively. According to the age of implantation, all participants were divided into two groups as 1 year old group(1-<2) and 2 years old group(2-<3). The vowel perception of mandarin early speech perception(MESP) test scores at 12, 24, 36 momths after implantation as well as the trends in vowel perception between group 1 and normal hearing pediatrics of the same age were analyzed to research the development of vowel perception in pediatric cochlear implants and the effect of implanted age as well as physiological age. Result:The scores improved notably in two groups with the increase of physiological age(P<0.01); The vowel perception of group 1 was significantly better than that of group 2(P<0.01), However, there were great difference between group 1 and normal hearing pediatrics of the same age. Conclusion:With the increase of physiological age, the vowel perception would be improved correspondingly within 3 years of pediatric cochlear implants under the age of 3; However, the earlier the age of implant, the better the vowel perception is.
