Abstract

Objectives: Evaluate intelligence quotient (IQ) scores among children with bilateral hearing loss (HL) pre- and post-cochlear implantation (CI) and compared with normative means.

Databases reviewed: PubMed (MEDLINE), Embase, Cochrane, and CINAHL databases searched until December 2021.

Methods: Studies of patients 1) 18 years or younger (2) with bilateral sensorineural HL diagnosis who underwent CI, and (3) with ≥1 specific IQ score post-CI were included. Mean differences in IQ scores pre- and post-CI and compared with normal-hearing controls were meta-analyzed. Studies not amenable to meta-analysis were qualitatively analyzed.

Results: Included 15 articles (636 patients, 247 age-matched normal-hearing controls), with mean (SD) age in years at CI (4.1 [1.5]) and neurocognitive testing (8.6 [1.6]). Children with HL had significant performance IQ score improvement post-CI (MD, 7.0; 95% confidence interval, 1.95 to 12.05; I2 = 0%), and full-scale IQ scores comparable to normal-hearing group (MD 1.52; 95% confidence interval -4.46 to 7.50; I2 = 0%). Qualitatively, 9 of 12 studies evaluating performance IQ and 5 of 6 studies evaluating full-scale IQ showed mean scores of children with CI comparable to normative means, whereas 5 of 6 studies reported verbal IQ scores lower than normative means.

Conclusions: Children with CI show significant improvement in full-scale and performance IQ testing, with a significant proportion achieving normal ranges scores. Verbal IQ scores remain lower than normative means, even after CI, likely due to the reduced access to sound before CI. Earlier implantation and therefore earlier access to sound may help lessen the impact on verbal IQ in these children.

人工耳蜗植入儿童的智商测试：系统回顾和荟萃分析。

目的：评价双侧听力损失（HL）患儿人工耳蜗植入（CI）前后的智商（IQ）得分，并与标准指标进行比较。检索数据库：PubMed （MEDLINE）、Embase、Cochrane和CINAHL数据库，检索至2021年12月。方法：纳入以下患者的研究：1)18岁或以下；2)双侧感觉神经性HL诊断并行CI； 3) CI后特定智商得分≥1的患者。与听力正常的对照组相比，ci前和ci后智商得分的平均差异进行meta分析。不适合荟萃分析的研究进行了定性分析。结果：纳入15篇文章（636例患者，247例年龄匹配的正常听力对照），平均（SD）年龄为CI(4.1[1.5])，神经认知测试（8.6[1.6]）。HL患儿ci后表现IQ得分显著提高(MD, 7.0；95%置信区间为1.95 ~ 12.05；I2 = 0%)，全面智商得分与听力正常组相当(MD 1.52；95%置信区间-4.46至7.50；I2 = 0%)。定性地说，12项评估表现智商的研究中有9项和6项评估全面智商的研究中有5项显示CI儿童的平均得分与标准均值相当，而6项研究中有5项报告语言智商得分低于标准均值。结论：CI患儿在全面和性能智商测试中表现出显著的改善，显著比例达到正常范围得分。言语智商得分仍然低于标准水平，即使在CI之后，可能是由于在CI之前减少了接触声音的机会。更早的植入，从而更早地接触到声音，可能有助于减轻对这些儿童语言智商的影响。
