Cochlear implants (CIs) can considerably improve the oral language of prelingual hearing-impaired children. However, because most studies have been performed with English speaking children, available information regarding Persian-speaking children is scarce. Therefore, this study compared measures of lexical diversity (numbers of different words and total words), and syntactic complexity (mean length of utterance) in Persian-speaking children with and without CIs.
A cross-sectional study with 20 children with CIs and 20 typically developing children was conducted. To collect the data, the children's language samples were gathered via picture descriptions. The first 50 utterances were analyzed.
All measures were significantly different between children with CIs and their typically developing age-matched peers, whereas no differences between children with CIs and their typically developing hearing age-matched peers were detected (p<0.05).
CIs have been recognized to be one of the most beneficial rehabilitation prostheses because they help children to acquire speech and language abilities similar to their typically developing hearing age-matched peers. After implantation, the performance of children with CIs is similar to the performance of normal children with the same hearing experience. The duration of the hearing experience after the implantation is an important factor for determining the development of speech and language abilities.
人工耳蜗（CI）可显著改善语前听力受损儿童的口语能力。然而，由于大多数研究是针对说英语的儿童进行的，关于说波斯语儿童的现有信息很少。因此，本研究比较了有和没有人工耳蜗的波斯语儿童在词汇多样性（不同单词数量和总单词数）和句法复杂性（话语平均长度）方面的指标。
对20名接受人工耳蜗植入的儿童和20名发育正常的儿童进行了横断面研究。为收集数据，通过图片描述收集儿童的语言样本。对前50个话语进行了分析。
接受人工耳蜗植入的儿童与其年龄匹配的发育正常同龄人之间的所有指标均存在显著差异，而接受人工耳蜗植入的儿童与其听力年龄匹配的发育正常同龄人之间未检测到差异（p<0.05）。
人工耳蜗已被认为是最有益的康复假体之一，因为它们帮助儿童获得与听力年龄匹配的发育正常同龄人相似的言语和语言能力。植入后，接受人工耳蜗植入的儿童的表现与有相同听力经历的正常儿童的表现相似。植入后听力经历的时长是决定言语和语言能力发展的一个重要因素。
