Cochlear implantation (CI) is an achievement that facilitates the acquisition of language skills in deaf children throughout the world. The use of this technology has a positive effect on all components of language acquisition (syntax, semantic, pragmatic, etc.). However, this positive impact is influenced by various factors. Understanding the strengths and weaknesses of studies on the development of language abilities can help improve these studies. Consequently, in the future, it will lead to the improvement of language rehabilitation in these children. Limited studies on children with CI in have been done so far. This article summarized the outcomes of scientific articles on the clinical efficacy of CI on Persian speaking children. This study also provided a clear picture of these studies by examining the quality of their methodologies and tools. Articles indexed in Google Scholar, Web of Science, Medline, Scopus and Iranian databases (Danesh Gostar, Magiran, and SID) were searched using keywords "language," "Cochlear implant", "Persian/ Farsi" in English and Persian languages with "and/or". Original articles investigated on children younger than 13 years old with hearing impairment and CI were included. Five hundred and twenty-three articles were found based on the keywords. Among all of these, 485 were excluded due to the title and the abstract; we selected 38, of which 24 were repeated. Finally, 14 articles remained. We reviewed the articles based on the preferred reporting items for systematic review and meta-analysis (PRISMA) and checklist and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE). Similar to international studies, Persian speaking children with CI have slower language development than their peers with normal hearing, but they are better than their peers who use hearing aids. The results of reviewing on quality of the articles showed that the studies could not meet reasonable quality because of the lack of a standard test in different aspects of Persian language and the absence of patients' databanks. These results also can be used by other nationalities that recently have started surveys on children with CIs.
人工耳蜗植入（CI）是一项成就，它有助于全世界聋儿获得语言技能。这项技术的使用对语言习得的所有组成部分（句法、语义、语用等）都有积极影响。然而，这种积极影响受到多种因素的影响。了解语言能力发展研究的优势和不足有助于改进这些研究。因此，在未来，这将有助于改善这些儿童的语言康复情况。到目前为止，针对人工耳蜗植入儿童的研究有限。本文总结了关于人工耳蜗植入对说波斯语儿童临床疗效的科学文章的成果。本研究还通过检查其方法和工具的质量，清晰地呈现了这些研究。在谷歌学术、科学网、医学索引、Scopus和伊朗数据库（Danesh Gostar、Magiran和SID）中检索索引的文章，使用英文和波斯文中的关键词“语言”“人工耳蜗”“波斯语/法尔斯语”，并使用“和/或”。纳入了对13岁以下有听力障碍且接受人工耳蜗植入的儿童进行研究的原创文章。根据关键词共找到523篇文章。其中，485篇因标题和摘要被排除；我们筛选出38篇，其中24篇重复。最后，剩下14篇文章。我们根据系统评价和荟萃分析的首选报告项目（PRISMA）、清单以及推荐分级、评估、制定和评价（GRADE）对文章进行了综述。与国际研究类似，说波斯语的人工耳蜗植入儿童的语言发展比听力正常的同龄人慢，但比使用助听器的同龄人要好。文章质量审查结果表明，由于波斯语不同方面缺乏标准测试以及缺乏患者数据库，这些研究未能达到合理的质量标准。其他最近开始对人工耳蜗植入儿童进行调查的国家也可以使用这些结果。
