(1) Objectives: This study reviews the use of electrocochleography (ECoG) as a tool for assessing the response of the peripheral auditory system and monitoring hearing preservation in the growing population of cochlear implant (CI) users with preserved hearing in the implanted ear. (2) Methods: A search was conducted in PubMed and CINAHL databases up to August 2020 to locate articles related to the ECoG measured during or after the cochlear implant (CI) surgery for monitoring purposes. Non-English articles, animal studies, literature reviews and editorials, case reports, and conference papers were excluded. The quality of studies was evaluated using the National Institute of Health (NIH) "Study Quality Assessment Tool for Case Series Studies". (3) Results: A total 30 articles were included for the systematic review. A total of 21 articles were intraoperative ECoG studies, while seven articles were postoperative studies. Two studies were conducted ECoG both during and after the surgery. Intraoperative ECoG studies focused on monitoring changes in ECoG response amplitudes during and/or after electrode insertion and predicting the scalar location of the electrode array. Postoperative ECoG studies focused on using the ECoG measurements to estimate behavioral audiometric thresholds and monitor pathophysiological changes related to delayed onset hearing loss postimplant. (4) Conclusions: ECoG is feasible to provide real-time feedback intraoperatively and has a potential clinical value to monitor the status of hearing preservation postoperatively in this CI population with residual acoustic hearing.
(1) 目的：本研究回顾了电 Cochleography（ECoG）在评估具有保留听力的植入耳的 Cochlear 植入（CI）使用者的外周听觉系统反应和监测听力保留方面的作用。(2) 方法：在 PubMed 和 CINAHL 数据库中进行了搜索，截至 2020 年 8 月，以查找与为监测目的在 Cochlear 植入（CI）手术期间或之后测量的 ECoG 相关的文章。排除非英语文章、动物研究、文献综述和社论、病例报告和会议论文。使用美国国立卫生研究院（NIH）的“病例系列研究质量评估工具”评估研究质量。(3) 结果：共纳入 30 篇文章进行系统评价。共有 21 篇为术中 ECoG 研究，7 篇为术后研究。有两项研究在手术期间和之后都进行了 ECoG。术中 ECoG 研究侧重于监测电极插入过程中或之后 ECoG 反应幅度的变化，并预测电极阵列的标量位置。术后 ECoG 研究侧重于使用 ECoG 测量来估计行为听力阈值，并监测与植入后延迟发生听力损失相关的病理生理变化。(4) 结论：ECoG 可在术中提供实时反馈，对于监测具有残余声觉听力的 CI 人群术后听力保留情况具有潜在的临床价值。
