Initial Surgeon Experiences With a Robotic-Assisted Cochlear Implant Electrode Array Insertion System

Area of Science:

• Otolaryngology
• Medical Robotics
• Surgical Innovation

Background:

• Cochlear implantation (CI) is a complex procedure.
• Robotic-assisted surgery offers potential benefits for precision and consistency.
• Integration of new robotic systems into surgical workflows requires careful assessment.

Purpose of the Study:

• To evaluate the integration of a single-use robotic-assisted cochlear implant (RA-CI) electrode array insertion system.
• To identify challenges and establish best practices for its use in CI surgery.
• To assess the learning curve and time impact of the RA-CI system.

Main Methods:

• A survey was conducted among 16 surgeons across 10 US hospitals.
• Data were collected on the use of a single-use RA-CI insertion system in CI surgeries.
• Outcomes measured included proficiency acquisition, estimated time addition, and recommended best practices.

Main Results:

• 121 RA-CI cases were performed, with all participating surgeons completing the survey.
• Most surgeons (62.5%) felt proficient within five cases.
• The RA system added an estimated 5-15 minutes to surgery duration for most users.
• Key best practices involved incision size, facial recess exposure, and device placement for optimal insertion.

Conclusions:

• Proficiency with the RA electrode array insertion system is achievable with fewer than five cases.
• Minimal adjustments to surgical approach and specific training on best practices are crucial for successful integration.
• The RA-CI system can be incorporated into CI surgery with a manageable increase in operative time.
