Early Clinical Experience With Robot-Assisted Electrode Insertion in Cochlear Implantation Using the Otoarm-Otodrive System.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
importanceManual cochlear implant (CI) electrode insertion remains surgeon-dependent and may contribute to intracochlear trauma. Robotic-assisted systems, such as the new Otoarm-Otodrive, offer motorized control at ultra-slow speeds that aim to minimize force fluctuations and pressure changes, potentially improving hearing preservation and surgical consistency.
objectiveTo describe the institutional experience, surgical workflow integration, and feasibility of robot-assisted cochlear implantation (CI) using the Otoarm-Otodrive system.
designRetrospective descriptive study of 50 consecutive robot-assisted CI cases.
settingTertiary referral otology center in Canada.
participantsFifty Adult patients undergoing cochlear implantation without cochlear malformation or ossification using a MED-EL device from January to October 2025.
interventionRobot-assisted cochlear electrode array insertion using the Otoarm-Otodrive (MED-EL) system.
main outcome measuresFeasibility (setup and insertion times), insertion depth, intraoperative challenges, and integration into operative workflow.
resultsThe additional time for robot setup and alignment averaged 374 seconds. Mean electrode insertion duration, performed at a standardized rate of 0.1 mm/second, was 444 seconds. Postoperative Otoplan analysis in 30 cases demonstrated a mean angular insertion depth of 575°. No major complications such as facial nerve palsy or infections, and no device-related complications occurred. All but 1 case achieved full insertion.
conclusionsRobot-assisted cochlear electrode insertion using the Otoarm-Otodrive system is safe, reproducible, and easily integrated into standard CI workflow. RELEVANCE: This first North American experience in using the Otoarm-Otodrive system demonstrates the feasibility of robotic cochlear implant insertion as a step toward achieving atraumatic implantation. Future studies will assess hearing preservation benefits and cost-effectiveness for broader adoption.
