The objective of this study was to examine receptive and expressive language development in children who received simultaneous bilateral cochlear implants (CIs) between 5 and 18 months of age and to compare the results with language development in chronologically age-matched children with normal hearing.
The study used a prospective, longitudinal matched-group design. Data were collected in a clinical setting at postoperative cochlear implant check-ups after 3, 6, 9, 12, 18, 24, 36, and 48 months of implant use. The sample included 42 children: 21 cochlear implant users and 21 with normal hearing, matched pairwise according to gender and chronological age. Communication assessments included the LittlEARS questionnaire, the Mullen Scale of Early Learning, and the Minnesota Child Development Inventory.
The cochlear implant users' hearing function according to LittlEARS was comparable to that of normal-hearing children within 9 months post-implantation. The mean scores after 9 and 12 months were 31 and 33, respectively in the prelingually deaf versus 31 and 34 in the normal-hearing children. The children's receptive and expressive language scores showed that after 12-48 months with cochlear implants, 81% had receptive language skills within the normative range and 57% had expressive language skills within the normative range. The number of children who scored within the normal range increased with increasing CI experience.
The present study showed that prelingually deaf children's ability to develop complex expressive and receptive spoken language after early bilateral implantation appears promising. The majority of the children developed language skills at a faster pace than their hearing ages would suggest and over time achieved expressive and receptive language skills within the normative range.
本研究的目的是考察5至18个月大时接受双侧同期人工耳蜗植入（CI）的儿童的接受性和表达性语言发展情况，并将结果与年龄匹配的听力正常儿童的语言发展情况进行比较。
本研究采用前瞻性纵向匹配组设计。在植入人工耳蜗后3、6、9、12、18、24、36和48个月的临床人工耳蜗检查中收集数据。样本包括42名儿童：21名人工耳蜗使用者和21名听力正常儿童，根据性别和实际年龄进行配对。沟通评估包括小耳朵问卷、马伦早期学习量表和明尼苏达儿童发展量表。
根据小耳朵问卷，人工耳蜗使用者在植入后9个月内的听力功能与听力正常儿童相当。语前聋儿童在9个月和12个月后的平均得分分别为31分和33分，而听力正常儿童分别为31分和34分。儿童的接受性和表达性语言得分显示，在使用人工耳蜗12至48个月后，81%的儿童接受性语言技能在正常范围内，57%的儿童表达性语言技能在正常范围内。得分在正常范围内的儿童数量随着人工耳蜗使用经验的增加而增加。
本研究表明，语前聋儿童在早期双侧植入后发展复杂的表达性和接受性口语的能力似乎很有前景。大多数儿童的语言技能发展速度比他们的听力年龄所显示的要快，并且随着时间的推移，在正常范围内实现了表达性和接受性语言技能。
