We investigated effects of aetiology and age at implantation on changes in threshold (T) levels, comfortable (C) levels and dynamic range (DR) for cochlear implants (CIs) in children over the first five years of life.
Information was collected at 6 months post-activation of CIs, and at 3 and 5 years of age.
One hundred and sixty-one children participating in the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study.
Children with neural and structural cochlear lesions had higher T-levels and C-levels as compared to those without these conditions. Parameter settings varied from manufacturer's defaults more often in the former than in the latter group. Investigation of the effect of age at implantation for children without neural and structural cochlear lesions showed that those implanted at ≤12 months of age had higher T-levels and narrower DR at 6 months post-activation, as compared to the later-implanted group. For both early- and later-implanted groups, the C-levels at 6 months post-activation were lower than those at age 3 and 5 years. There were no significant differences in T-levels, C-levels, or DR between age 3 and 5 years.
Aetiology and age at implantation had significant effects on T-levels and C-levels.
我们研究了病因及植入时年龄对儿童人工耳蜗（CI）在出生后前五年内阈值（T）水平、舒适（C）水平和动态范围（DR）变化的影响。
在人工耳蜗激活后6个月、3岁和5岁时收集信息。
161名参与听力障碍儿童纵向结局（LOCHI）研究的儿童。
与无神经和结构耳蜗病变的儿童相比，患有神经和结构耳蜗病变的儿童T水平和C水平更高。前一组参数设置偏离制造商默认值的情况比后一组更频繁。对无神经和结构耳蜗病变儿童植入时年龄影响的研究表明，与较晚植入组相比，在≤12个月时植入的儿童在激活后6个月时T水平更高且DR更窄。对于早期和晚期植入组，激活后6个月时的C水平均低于3岁和5岁时的水平。3岁和5岁时T水平、C水平或DR无显著差异。
病因及植入时年龄对T水平和C水平有显著影响。
