Abstract
Objective: To evaluate the safety and outcomes of robot-assisted electrode insertion in cochlear implantation. Methods: We first reported the case of robot-assisted electrode insertion of cochlear implantation in October 2019. A new slim electrode array of Nurotron cochlear implant (CS-10A TM) and RobOtol(®) robot system were used in this case. The robotic assistance procedures, surgical outcomes were analyzed. Results: Robot-assisted electrode insertion was successfully performed in this adult patient. The preparation of robot system cost six minutes, the electrode array was slowly and fully inserted into tympanic scala with robot assistance. No damage in the surgical field occurred by the robotic instrument. Intraoperative electrode impedances and neural response measurements were normal. No postoperative complications occurred. Up to three months of follow up after implantation, the cochlear implant functioned well and rehabilitated hearing was satisfactory. Conclusion: Otological robot system shows its advantage in the elimination of human involuntary tremors and the augmentation of accuracy during micromanipulation, it could safely assist cochlear implantation to realize minimally invasive and full tympanic scala insertion of the electrode array, and to ensure the good preservation of the intracochlear fine structure.
