Content : Introduction: Surgical robots enhance electrode array insertion during cochlear implantation by minimizing hand tremors and allowing slow, precise movements. This study evaluates electrode array translocation positions after robot-assisted versus manual insertions.
Methods: The study retrospectively included 180 cochlear implant recipients, with 90 undergoing robot-assisted insertion (RobOtol®) matched 1:1 with manual insertions. Straight arrays (Cochlear CI522/622, Advanced Bionics SlimJ, MedEl Flex28, Oticon EVO) and one perimodiolar array (AB MidScala) were used. Postoperative CT scans were analyzed to determine electrode positions classified as scala tympani or scala vestibule and translocation positions (apical, intermediate, basal).
Results: No significant difference was found in translocation ratios between robotic and manual insertions across all array types. Translocation positions varied for lateral wall arrays with apical (48%), intermediate (31%), proximal (3%), and intermediate+distal (18%) translocations. MidScala arrays showed intermediate translocations, often leading to isolated basilar membrane perforations.
Conclusion: Electrode array translocation occurs with all types but varies by array type and position, potentially causing basilar membrane detachment or perforation.
