Children with mental retardation (MR) obtain demonstrable benefit from cochlear implantation, and their postoperative performance was tempered by the degree of MR.
The purpose of this study was to investigate the performance of children with MR after implantation, and to explore their progress according to the degree of MR.
Fifteen implanted children with MR were included. Progress in speech perception, speech intelligibility, and language was measured using Categories of Auditory Performance, monosyllabic word test, Speech Intelligibility Rating, and Language Scale before and after implantation. We retrospectively examined outcomes and explored the association between the progress and the degree of MR after implantation. We compared monosyllabic word test scores using repeated-measures ANOVA.
Speech perception and speech intelligibility for children with mild MR improved consistently after implantation. After implantation, monosyllabic word test scores did not differ significantly between children with mild MR and children with no additional disabilities. Although language development of children with mild MR was slow, they could communicate verbally 3 years after implantation. Children with moderate MR progressed more slowly and had limitations in speech and language development, and these children could communicate by vocalization and gesture 3 years after implantation.
智力迟钝（MR）儿童可从人工耳蜗植入中获得显著益处，且其术后表现受智力迟钝程度的影响。
本研究旨在调查智力迟钝儿童植入人工耳蜗后的表现，并根据智力迟钝程度探索其进展情况。
纳入15名植入人工耳蜗的智力迟钝儿童。在植入前后，使用听觉表现分类、单音节词测试、言语可懂度评分和语言量表来测量言语感知、言语可懂度和语言方面的进展。我们回顾性地检查了结果，并探讨了植入后进展与智力迟钝程度之间的关联。我们使用重复测量方差分析比较单音节词测试分数。
轻度智力迟钝儿童的言语感知和言语可懂度在植入后持续改善。植入后，轻度智力迟钝儿童与无其他残疾儿童的单音节词测试分数无显著差异。虽然轻度智力迟钝儿童的语言发展缓慢，但他们在植入后3年能够进行口头交流。中度智力迟钝儿童进展较慢，在言语和语言发展方面存在局限性，这些儿童在植入后3年能够通过发声和手势进行交流。
