Language skills of profoundly deaf children who received cochlear implants under 12 months of age: a preliminary study

Abstract

Conclusion: This study demonstrated that children who receive a cochlear implant below the age of 2 years obtain higher mean receptive and expressive language scores than children implanted over the age of 2 years.

Objective: The purpose of this study was to compare the receptive and expressive language skills of children who received a cochlear implant before 1 year of age to the language skills of children who received an implant between 1 and 3 years of age.

Subjects and methods: Standardized language measures, the Reynell Developmental Language Scale (RDLS) and the Preschool Language Scale (PLS), were used to assess the receptive and expressive language skills of 91 children who received an implant before their third birthday.

Results: The mean receptive and expressive language scores for the RDLS and the PLS were slightly higher for the children who were implanted below the age of 2 years compared with the children who were implanted over 2 years old. For the PLS, both the receptive and expressive mean standard scores decreased with increasing age at implantation.

Figure 1
The expressive and receptive language quotient data from the Reynell Developmental Language scale are presented as a function of age at implantation. Each child had 2–3 years of experience with his or her cochlear implant when these data were collected. The numbers of children who were included in each group are listed in the bottom panel. The solid line within the box plot shows the median score and the dashed-dot-dot line represents the mean score. See text for further explanation of the box plots.
Figure 2
Figure 2
The auditory comprehension and expressive communication standard score data from the Preschool Language Scale are shown as a function of age at implantation. The numbers of children included in each group are displayed in the bottom panel. Each open circle represents one data point from one child. The children had used their devices for 6 months to 1 year prior to administration of the PLS.
