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

Area of Science:

• Otorhinolaryngology
• Medical Robotics
• Pediatric Surgery

Background:

• Cochlear implantation is a vital treatment for pediatric hearing loss.
• Minimizing intracochlear trauma during electrode insertion is crucial for long-term outcomes.
• Pediatric anatomy presents unique challenges for surgical procedures.

Purpose of the Study:

• To assess the safety and usability of a robotic-assisted electrode insertion system for pediatric cochlear implantation.
• To evaluate the incidence of device-related serious adverse events (SAEs) in children aged 4-12 years.
• To determine the procedural success and efficiency of robotic assistance in this population.

Main Methods:

• A prospective, non-randomized, multicenter study involving 14 pediatric patients (4-12 years).
• Unilateral cochlear implantation using a robotic-assisted electrode array insertion system.
• Primary outcome: device-related SAEs within 30 days post-activation; Secondary outcomes: insertion success, time, speed, and electrode position.

Main Results:

• Successful robotic-assisted electrode insertion in all 14 patients.
• No device-related SAEs occurred within 30 days post-activation; all 7 reported adverse events were non-device related.
• Surgeons reported high success rates (93%) for device setup, use, and detachment, managing pediatric anatomic variations effectively.

Conclusions:

• Robotic-assisted cochlear implant electrode insertion is safe and effective in pediatric patients (4-12 years) across multiple centers.
• The system achieved high procedural success rates without device-related SAEs.
• Adapting to pediatric anatomical constraints is key for safe robotic-assisted cochlear implantation, with potential to minimize intracochlear trauma.
