Cochlear implants are crucial for addressing severe-to-profound hearing loss, with the success of the procedure requiring careful electrode placement. This scoping review synthesizes the findings from 125 studies examining the factors influencing insertion forces (IFs) and intracochlear pressure (IP), which are crucial for optimizing implantation techniques and enhancing patient outcomes. The review highlights the impact of variables, including insertion depth, speed, and the use of robotic assistance on IFs and IP. Results indicate that higher insertion speeds generally increase IFs and IP in artificial models, a pattern not consistently observed in cadaveric studies due to variations in methodology and sample size. The study also explores the observed minimal impact of robotic assistance on reducing IFs compared to manual methods. Importantly, this review underscores the need for a standardized approach in cochlear implant research to address inconsistencies and improve clinical practices aimed at preserving hearing during implantation.
人工耳蜗植入对于重度至极重度听力损失至关重要，手术的成功需要仔细放置电极。本范围综述综合了 125 项研究的结果，这些研究探讨了影响插入力 (IF) 和内耳蜗压力 (IP) 的因素，这些因素对于优化植入技术和提高患者预后至关重要。该综述强调了变量的影响，包括插入深度、速度以及使用机器人辅助对 IF 和 IP 的影响。结果表明，在人工模型中，较高的插入速度通常会增加 IF 和 IP，但在尸体研究中并非如此，因为方法和样本量的差异导致这一模式不一致。该研究还探讨了与手动方法相比，机器人辅助对降低 IF 的观察到的最小影响。重要的是，本综述强调了在人工耳蜗植入研究中需要采用标准化方法来解决不一致性问题，并改进旨在在植入过程中保护听力的临床实践。
