Abstract：
Background: Various representations exist in the literature to visualize electrocochleography (ECochG) recordings along the basilar membrane (BM). This lack of generalization complicates comparisons within and between cochlear implant (CI) users, as well as between publications. This study synthesized the visual representations available in the literature via a systematic review and provides a novel approach to visualize ECochG data in CI users. Methods: A systematic review was conducted within PubMed and EMBASE to evaluate studies investigating ECochG and CI. Figures that visualized ECochG responses were selected and analyzed. A novel visualization of individual ECochG data, the ZH-ECochG Bode plot (ZH = Zurich), was devised, and the recordings from three CI recipients were used to demonstrate and assess the new framework. Results: Within the database search, 74 articles with a total of 115 figures met the inclusion criteria. Analysis revealed various types of representations using different axes; their advantages were incorporated into the novel visualization framework. The ZH-ECochG Bode plot visualizes the amplitude and phase of the ECochG recordings along the different tonotopic regions and angular insertion depths of the recording sites. The graph includes the pre- and postoperative audiograms to enable a comparison of ECochG responses with the audiometric profile, and allows different measurements to be shown in the same graph. Conclusions: The ZH-ECochG Bode plot provides a generalized visual representation of ECochG data, using well-defined axes. This will facilitate the investigation of the complex ECochG potentials generated along the BM and allows for better comparisons of ECochG recordings within and among CI users and publications. The scripts used to construct the ZH-ECochG Bode plot are provided by the authors.
摘要：
背景：文献中存在各种表示以可视化沿基底膜（BM）的心电图（ECochG）记录。缺乏泛化使人工耳蜗（CI）使用者内部和使用者之间的比较变得复杂。以及出版物之间。本研究通过系统综述综合了文献中可用的视觉表示，并提供了一种新颖的方法来可视化CI用户中的ECochG数据。方法：在PubMed和EMBASE中进行了系统评价，以评估研究ECochG和CI的研究。选择并分析可视化ECochG反应的图。单个ECochG数据的新颖可视化，ZH-ECochG波德图(ZH=苏黎世)，是被设计出来的，来自三名eCI接受者的录音用于演示和评估新框架。结果：在数据库搜索中，总共有115个数字的74篇文章符合纳入标准。分析揭示了使用不同轴的各种类型的表示；它们的优势被纳入新颖的可视化框架中。ZH-ECochGBode图可视化了ECochG记录沿记录位点的不同色调区域和角度插入深度的振幅和相位。该图包括术前和术后的听力图，以便将ECochG反应与听力测定曲线进行比较。并允许不同的测量显示在同一图表中。结论：ZH-ECochGBode图提供了ECochG数据的广义可视化表示，使用定义明确的轴。这将有助于调查沿BM产生的复杂ECochG电位，并允许更好地比较CI用户和出版物中的ECochG记录。用于构建ZH-ECochGBode图的脚本由作者提供。
