Abstract：
Robotics in otology has been developing in many directions for more than two decades. Current clinical trials focus on more accurate stapes surgery, minimally invasive access to the cochlea and less traumatic insertion of cochlear implant (CI) electrode arrays. In this study we evaluated the use of the RobOtol® (Collin, Bagneux, France) otologic robot to insert CI electrodes into the inner ear with intraoperative ECochG analysis. This prospective, pilot study included two adult patients implanted with Advanced Bionics (Westinghouse PI, CA, USA) cochlear implant, with HiFocus™ Mid-Scala electrode array. The standard surgical approach was used. For both subjects, who had residual hearing in the implanted ear, intraoperative and postoperative ECochG was performed with the AIMTM system. The surgeries were uneventful. A credible ECochG response was obtained after complete electrode insertion in both cases. Preoperative BC thresholds compared to intraoperative estimated ECochG thresholds and 2-day postoperative BC thresholds had similar values at frequencies where all thresholds were measurable. The results of the ECochG performed one month after the surgery showed that in both patients the hearing residues were preserved for the selected frequencies. The RobOtol® surgical robot allows for the correct, safe and gentle insertion of the cochlear implant electrode inside the cochlea. The use of electrocochleography measurements during robotic cochlear implantation offers an additional opportunity to evaluate and modify the electrode array insertion on an ongoing basis, which may contribute to the preservation of residual hearing.
摘要：
20多年来，耳科学中的机器人技术一直在向多个方向发展。目前的临床试验集中在更精确的骨手术上，微创进入耳蜗和较少的创伤性耳蜗植入（CI）电极阵列的插入。在这项研究中，我们评估了RobOtol®(Collin，Bagneux,法国）耳科机器人通过术中ECochG分析将CI电极插入内耳。这个未来,试点研究包括两名植入高级仿生学的成年患者(西屋PI，CA,美国)人工耳蜗，与HiFocus™Mid-Scala电极阵列。使用标准手术方法。对于这两个主题，植入的耳朵有残余听力，术中和术后使用AIMTM系统进行ECochG.手术很顺利。在两种情况下，完全插入电极后都获得了可靠的ECochG响应。术前BC阈值与术中估计的ECochG阈值和术后2天BC阈值相比，在所有阈值均可测量的频率下具有相似的值。手术后一个月进行的ECochG结果显示，在两名患者中，听力残留物都保留了选定的频率。RobOtol®手术机器人允许正确的，在耳蜗内安全和温和地插入耳蜗植入电极。在机器人人工耳蜗植入过程中使用电子耳蜗成像测量提供了一个额外的机会来评估和修改电极阵列插入。这可能有助于保留残余听力。
