目的：评估人工耳蜗植入术后语前聋儿童口语语法理解的发展，并比较他们的语法能力与他们的听力peer.Design：82个连续语前聋儿童长达5年植入后的前瞻性研究。植入时儿童年龄小于7岁（平均年龄SD，4.2 ± 1.3岁）。所有患者均接受了相同的多通道人工耳蜗植入系统。没有孩子失去了后续行动，并没有从study.Setting排除：三级转诊人工耳蜗center.Methods：儿童进行了评估，使用测试接受的语法。这个单独管理，多项选择测试，旨在评估英语语言中的语法对比的理解，也允许测试对象和他们的正常听力peer.Results：植入前，只有一小部分（2%）的语前聋儿童的语法理解的直接比较高于他们的正常听力同龄人的第一百分位数。植入后3年和5年，这一比例分别增加到40%和67%;植入后5年，20%的儿童表现在第25百分位数和第75百分位数之间或更好。在4岁之前接受人工耳蜗的儿童中，这一比例达到36%。结论：语前聋儿童人工耳蜗植入后口语语法习得明显延迟。然而，在人工耳蜗植入后，语法技能的发展有明显的趋势，并且在年龄较小的时候接受植入的儿童取得了最大的进步。这些研究结果支持目前的趋势。走向早期植入。
Objectives: To assess the development of grammar comprehension in spoken language in prelingually deaf children following cochlear implantation and compare their grammatical abilities with those of their hearing peers.Design: A prospective study of 82 consecutive prelingually deaf children up to 5 years following implantation. The children were less than 7 years old at the time of implantation (mean age SD, 4.2 +/- 1.3 years). All received the same multichannel cochlear implant system. No child was lost to follow-up and there were no exclusions from the study.Setting: Tertiary referral cochlear implant center.Methods: The children were assessed using the Test for Reception of Grammar. This individually administered, multiple-choice test designed to assess the understanding of grammatical contrasts in the English language also allows direct comparison of grammar comprehension between test subjects and their normal-hearing peers.Results: Before implantation, only a small proportion (2%) of prelingually deaf children were above the first percentile of their normal-hearing peers. This percentage increased to 40% and 67%, respectively, 3 and 5 years after implantation; and 5 years after implantation, 20% of the children performed between the 25th and the 75th percentile or better. In the subgroup of children who received their cochlear device before the age of 4 years, this percentage reached 36%.Conclusions: Spoken language grammar acquisition in prelingually deaf children with a cochlear implant was found to be considerably delayed. However, there was a clear trend toward the development of grammar skills following cochlear implantation, and the greatest advance was made by children who received their implant at a younger age. These findings support the present trend. toward early implantation.
