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.
结论
本研究表明，2岁以下接受人工耳蜗植入的儿童在接受性和表达性语言平均得分方面高于2岁以上接受植入的儿童。
目的
本研究的目的是比较1岁前接受人工耳蜗植入的儿童与1至3岁接受植入的儿童的接受性和表达性语言技能。
对象与方法
采用标准化语言测试工具，即雷尼尔发育性语言量表（RDLS）和学前语言量表（PLS），对91名在3岁生日前接受植入的儿童的接受性和表达性语言技能进行评估。
结果
与2岁以上接受植入的儿童相比，2岁以下接受植入的儿童在RDLS和PLS上的接受性和表达性语言平均得分略高。对于PLS，接受性和表达性平均标准得分均随着植入年龄的增加而降低。
