Robotic-Assisted Electrode Insertion for Pediatric Cochlear Implantation: A Multicenter Study.

OBJECTIVE

To evaluate the safety and use of a robotic-assisted electrode insertion system for cochlear implantation in pediatric patients aged 4 to 12 years.

METHODS

Fourteen pediatric patients (ages 4-12 years) underwent unilateral cochlear implantation with robotic-assisted electrode array insertion in this prospective, non-randomized, multicenter study. The primary outcome was the incidence of device-related serious adverse events (SAEs) through 30 days after cochlear implant activation. Secondary outcomes included successful electrode insertion using the robotic-assisted system, insertion time and speed, and evaluation of electrode position.

RESULTS

All 14 patients underwent successful robotic-assisted electrode insertion with no device-related serious adverse events through 30 days post-activation. Seven adverse events were reported, all non-device related and resolved without sequelae. Surgeons reported successful device setup, use, and detachment in 93% of cases. Anatomic considerations unique to pediatric cases-such as smaller mastoid cavities and thinner cortex at the mounting site-were successfully managed with preoperative planning and intraoperative modifications.

CONCLUSIONS

Robotic-assisted cochlear implant electrode insertion in children aged 4-12 years was safe across multiple centers, with high procedural success rates and no device-related SAEs. Awareness of unique pediatric anatomic constraints and technical adjustments can support safe device mounting and controlled insertion. Given the lifespan and potential for new or emerging technologies for the pediatric population, the potential of robotic assistance to reduce intracochlear trauma is an important consideration.
