Abstract：
To conduct critical assessment of the literature on the effects of cochlear implantation on adults\' cognitive abilities.
PubMed, Scopus, Lilacs, Web of Science, Livivo, Cochrane, Embase, PsycInfo, and grey literature were searched. Eligibility criteria: age 18 or over with severe-to-profound bilateral hearing loss, cochlear implantation, cognitive test before and after implantation. Risk of bias was assessed using ROB, ROBINS-I and MASTARI tools. Meta-analysis was performed.
Out of 1830 studies, 16 met the inclusion criteria.
On AlaCog test, significant improvement was found after implantation [MD = -46.64; CI95% = -69.96 to -23.33; I2 = 71%]. No significant differences were found on the Flanker, Recall, Trail A and n-back tests (p > 0.05). For MMSE, no significance was found [MD 0.63; CI 95% = -2.19 to 3.45; I2 = 88%]. On TMT, an overall significant effect with a 9-second decrease in processing speed post-implantation [MD = -9.43; CI95% = -15.42 to -3.44; I2 = 0%].
Cognitive improvements after cochlear implantation may depend on time and the cognitive task evaluated. Well-designed studies with longer follow-up are necessary to examine whether cochlear implantation has a positive influence on cognitive abilities. Development of cognitive assessment tools to hearing-impaired individuals is needed.

摘要：
UNASSIGNED：对人工耳蜗植入对成年人认知能力影响的文献进行批判性评估。
未经授权：PubMed，Scopus,丁香花,WebofScience,Livivo,科克伦,Embase,PsycInfo,搜索了灰色文献。资格标准：年龄18岁或以上，患有严重至严重的双侧听力损失，人工耳蜗植入,植入前后的认知测试。使用ROB评估偏倚风险，ROBINS-I和MASTARI工具。进行Meta分析。
未经评估：在1830项研究中，16符合纳入标准。
未经评估：在AlaCog测试中，植入后发现显著改善[MD=-46.64;CI95%=-69.96~-23.33;I2=71%].在Flanker上没有发现显著差异，回想一下，TrailA和n-back检验(p>0.05)。对于MMSE，无显著性[MD0.63;CI95%=-2.19~3.45;I2=88%].在TMT上，总体效果显著,植入后处理速度降低9秒[MD=-9.43;CI95%=-15.42~-3.44;I2=0%].
UNASSIGNED：人工耳蜗植入后的认知改善可能取决于时间和评估的认知任务。有必要进行精心设计的长期随访研究，以检查人工耳蜗植入是否对认知能力有积极影响。需要开发针对听力受损个体的认知评估工具。
