目的：通过评估双侧先天性耳聋人工耳蜗植入者的言语感知来评估植入年龄的影响。设计：对60名至少有2年经验的人工耳蜗使用者（植入时年龄，1.01 - 22.0岁）进行回顾性队列分析。他们的结局表现由以下变化定义：i）基于术后评估结果的言语感知类别（SPC）评分和ii）植入后参加的教育类型。在不同植入年龄（2、3、4、5和6岁）分析植入年龄与SPC评分的相关性。在植入后6、12和24个月比较植入时特定年龄的SPC评分。植入年龄对教育选择的影响进行了评估，通过分析从聋哑学校到主流教育的45名儿童谁是10岁之前，因为年龄较大的儿童不太可能作出这样的改变。结果：2、3、4、5和6岁时植入的儿童在植入后24个月的SPC评分均获得显著改善。最大的改善是在植入后24个月，在3岁之前手术。对于所有年龄组，植入后24个月的改善大于12个月，而后者大于植入后6个月的改善。3岁之前植入的儿童与3岁至10岁之间植入的儿童的比较显示，植入后教育的选择存在显着差异。在3岁之前植入的儿童更有可能在植入后接受主流教育。结论：本研究的结果与当前的观点一致，即在较年轻的年龄植入可提供更大的益处。对于3岁之前植入的儿童，接受主流教育的比例明显较高，这可能是早期植入的潜在好处，可以减轻政府提供特殊教育的负担。
Objective: To evaluate the effect of age at implantation by assessment of speech perception in cochlear implant users with bilateral congenital deafness. Design: A retrospective cohort analysis of 60 cochlear implant users (age at implantation, 1.01 to 22.0 yr) who have at least 2 yr of experience. Their outcome performance was defined by the change in i) speech perception category (SPC) score based on postoperative assessment results and ii) the type of education attended after implantation. The association of age at implantation with SPC scores was analyzed at different ages at implantation (2, 3, 4, 5, and 6 yr old). The SPC scores for a particular age at implantation were compared at 6, 12, and 24 mo after implantation. The impact of age at implantation on choice of education was evaluated by analyzing the transition from a school for the deaf to mainstream education for the 45 children who were operated on before the age of 10, because older children are less likely to make such a change. Results: Children implanted at the ages of 2, 3, 4, 5, and 6 yr all obtained significant improvements in SPC scores 24 mo after implantation. The greatest improvement was noted at 24 mo after implantation among those operated on before age 3. For all age groups, improvement at 24 mo after implantation is greater than at 12 mo, whereas the latter is greater than the improvement noted at 6 mo after implantation. Comparison of children implanted before the age of 3 and between ages 3 and 10 showed a significant difference in the choice of education after implantation. Children who were implanted before the age of 3 were more likely to attend mainstream education after implantation. Conclusion: Results from the present study are consistent with the current belief that implantation at a younger age provides greater benefit. The proportion of children attending mainstream education was significantly higher for those implanted before age 3, which may be a potential benefit to early implantation for relieving the burden of governments in providing special education.
