Background and Objectives The objective of this study was to examine the effect of earlycochlear implantation (CI) performed in infants less than 12 months of age. Subjects and Method Twenty-five children who received their first CI before 12 months ofage were included in this study (infant group). The speech perception and language outcomesof these children were compared with those of 14 children who received their first CI between13 and 24 months of age (older group). All children received sequential bilateral CI with theinter-stage interval of less than 2 years. Speech perception was measured using Categories ofAuditory Performance, monosyllabic word test and sentence test, and language ability wasmeasured using Sequenced Language Scale for Infants, Preschool Receptive-Expressive LanguageScale, or Receptive & Expressive Vocavulary Test, depending on the age at the time oftesting. Results There were no significant differences in speech perception abilities between the infantgroup and the older group. The mean expressive language score of infant group was higherthan that of the older group, but the difference was not statistically significant. However, thereceptive language score of infant group was significantly higher than that of the older group. Conclusion Children who received CI before 12 months of age achieved better receptivelanguage ability than those who received it after 12 months of age. Thus CI should be performedas early as before 12 months of age to achieve better language ability.
