侧壁、蜗轴周围和中等尺度电极在人工耳蜗植入手术中的结果比较：一项Meta分析。

文献信息

中文摘要

引言： 人工耳蜗（CI）是大多数重度至极重度听力损失病例的标准治疗方法。CI可使用不同类型的电极。
目的： 比较CI手术中侧壁、中等尺度和蜗轴周围电极对耳蜗的创伤以及听力保留（如有残余听力）的情况。
数据综合： 我们于2022年6月在PubMed/MEDLINE、Scopus、Web of Science和Cochrane Library数据库中进行了全面检索，检索截至该年发表的文献。我们纳入了以英文发表、涉及人类受试者、关于CI手术中电极类型的研究，并排除了实验室和观点性研究。本综述遵循2009年系统评价和Meta分析首选报告项目（PRISMA）声明的指南。我们找到了21项研究；每种电极的听力保留率如下：侧壁电极——53%；蜗轴周围电极——35%；中等尺度电极——58%。侧壁和中等尺度电极对残余听力的保留优于蜗轴周围电极。每种电极的耳蜗创伤率如下：侧壁电极——61%；蜗轴周围电极——29%；中等尺度电极——16%。
结论： CI中功能性残余听力的保留率在侧壁和中等尺度电极中高于蜗轴周围电极。

英文摘要

INTRODUCTION: Cochlear implant (CI) is the standard of care for most cases of severe-to-profound hearing loss. Different electrodes are available for CI.
OBJECTIVE: To compare the lateral wall, midscala, and perimodiolar electrodes in CI surgery in terms of trauma to the cochlea and hearing preservation (if there is residual hearing).
DATA SYNTHESIS: We performed a comprehensive search on the PubMed/MEDLINE, Scopus, Web of Science, and Cochrane Library databases in June 2022 for articles in the literature published until this year. We included studies published in English, involving human subjects, and regarding the types of electrodes in CI surgery, and we excluded laboratory and opinion studies. The current review followed the guidelines of the 2009 Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. We found 21 studies; the hearing preservation rates with each electrode were as follows: lateral wall electrode - 53%; perimodiolar electrode - 35%; and midscala electrode - 58%. The lateral wall and midscala electrodes presented better preservation of residual hearing than the perimodiolar electrode. The rates of cochlear trauma with each electrode were as follows: lateral wall electrode - 61%; perimodiolar electrode - 29%; and midscala electrode - 16%.
CONCLUSION: The rates of preservation of functional residual hearing in CI are higher in lateral wall and midscala electrodes than in perimodiolar electrodes.
