The purpose of this study is to analyze the development of musicality in children after cochlear implantation, and provide a clinical database for the evaluation of their musicality.
Twenty-six children with cochlear implants (CI group) participated in this research. They received cochlear implants at the age of 11 to 68 months with a mean of 35.6 months. Seventy-six infants as a control group aged from 1 to 24 months with a mean of 6.1 months participated in this study, whose hearing were considered normal by passing the case history collection, high-risk registers for hearing loss and hearing screening using DPOAE. The music and young children with CIs: Musicality Rating Scale was used to evaluate their musicality. The evaluation was performed before cochlear implantation and 1, 3, 6, 9, 12, 24 months after cochlear implantation for children with cochlear implants. The evaluation was also performed at 1, 3, 6, 9, 12, 24 months for children with normal hearing.
The mean scores of musicality showed significant improvements with time of CI use for CI group (P<0.05). The mean scores of musicality also showed significant improvements with time for control group (P<0.05). There were no significant differences in mean scores between CI group and control group at 1, 3, 6, 9, 12 months of hearing age by rank sum test (P>0.05). Significant difference was noted between the two groups at 24 months (P<0.05).
The musicality of children with cochlear implants improved significantly with time after cochlear implantation. The most rapid growth was found in the first year after cochlear implantation.
本研究旨在分析人工耳蜗植入术后儿童音乐能力的发展情况，并为评估其音乐能力提供临床数据库。
26名人工耳蜗植入儿童（CI组）参与了本研究。他们在11至68个月龄时接受人工耳蜗植入，平均年龄为35.6个月。76名年龄在1至24个月、平均年龄为6.1个月的婴儿作为对照组参与本研究，通过病史收集、听力损失高危登记以及使用畸变产物耳声发射（DPOAE）进行听力筛查，其听力被认为正常。使用音乐与人工耳蜗植入儿童：音乐能力评定量表来评估他们的音乐能力。对人工耳蜗植入儿童在人工耳蜗植入术前以及术后1、3、6、9、12、24个月进行评估。对听力正常儿童也在1、3、6、9、12、24个月进行评估。
CI组音乐能力的平均得分随人工耳蜗使用时间有显著提高（P<0.05）。对照组音乐能力的平均得分也随时间有显著提高（P<0.05）。通过秩和检验，CI组和对照组在听力年龄1、3、6、9、12个月时平均得分无显著差异（P>0.05）。两组在24个月时存在显著差异（P<0.05）。
人工耳蜗植入儿童的音乐能力在人工耳蜗植入术后随时间显著提高。在人工耳蜗植入后的第一年增长最为迅速。
