Robotic Insertion of Cochlear Implants and Vestibular Function in Children.

Area of Science:

• Otorhinolaryngology
• Neurosurgery
• Biomedical Engineering

Background:

• Cochlear implantation (CI) is a vital treatment for pediatric hearing loss.
• Vestibular function preservation is crucial for balance and overall well-being post-CI.
• Evaluating novel surgical techniques like robotic-assisted insertion is essential for optimizing CI outcomes.

Purpose of the Study:

• To investigate the impact of robotic-assisted electrode array insertion on vestibular function in pediatric CI patients.
• To compare vestibular outcomes between robotic-assisted and traditional manual CI surgery.
• To assess the preservation of saccular and canal function using objective vestibular tests.

Main Methods:

• A retrospective study comparing 42 pediatric ears with robotic-assisted CI and 38 with manual CI.
• Vestibular function assessed pre- and post-operatively using cervical vestibular evoked myogenic potentials (cVEMP) and video head impulse test (vHIT).
• Statistical analysis included Fisher exact test and Wilcoxon rank-sum test to compare outcomes.

Main Results:

• Robotic-assisted CI showed significantly higher saccular function preservation (100% vs. 85%, P=0.02).
• No significant differences were observed in canal function preservation between robotic and manual groups via vHIT (92% vs. 100%).
• Per-canal vHIT gain analysis revealed no significant changes in any semicircular canal.

Conclusions:

• Robotic-assisted electrode array insertion demonstrates superior preservation of saccular function post-pediatric CI compared to manual techniques.
• The findings suggest that robotic insertion may be less traumatic to the vestibule, aiding in saccular function preservation.
• This technique holds promise for improving vestibular outcomes in pediatric cochlear implantation.
