The value of nonverbal intelligence in cochlear implant

AbstractAbstractBackground Congenital sensorineural hearing loss is a common congenital condition.Objectives The purpose of this study was to assess the correlation between nonverbal mental development and the effect of post-cochlear implant in children.Material and methods The study is a retrospective analysis of the CI program implemented at the ENT in the Lanzhou University Second Hospital (China). We reviewed data of 225 children who received CI between 2015 and 2018. Finally, 115 children met the inclusion criteria. Our hospital used The Griffith mental development scales to evaluate the preoperative non-verbal intelligence. The outcome of CI was evaluated using the categories of IT-MAIS, MUSS, CAP and SIR at 2 years after surgery. The associations between the preoperative non-verbal development quotient (DQ) and the postoperative outcomes were analyzed.Results Preoperative non-verbal DQ correlates with the long-term postoperative result, especially the Eye‐hand co-ordination and Performance DQ.Conclusions and Significance Preoperative non-verbal intelligence would predict postoperative effect. The single postoperative scale does not fully reflect the postoperative result.Chinese Abstract背景：先天性感音神经性听力损失是一种常见的先天性疾病。目的：本研究的目的是评估非语言心理发育与儿童人工耳蜗植入效果之间的相关性。材料和方法：该研究是对在兰州大学第二医院（中国）耳鼻喉科进行的CI 项目的一项回顾性分析。 我们审查了在 2015 年至 2018 年期间接受CI 的225 名儿童的数据。最终, 115 名儿童符合纳入标准。 我们医院使用Griffith智力发展量表评估术前非语言智力。在手术后 2 年使用 IT-MAIS、MUSS、CAP 和 SIR 的类别对CI 的结果进行评估。分析了术前非语言发育商数 (DQ) 与术后结果之间的关联。结果：术前非语言 DQ 与术后远期结果相关, 尤其是眼手协调和表现DQ。结论与意义：术前非语言智力可预测术后影响。 单一的术后量表并不能完全反映术后结果。Keywords: Nonverbal intelligencehearing losscochlear implant AcknowledgementIn addition, I would like to express my gratitude to Dr. Bian for help on polishing the article.
