Robot-assisted cochlear implantation using the RobOtol system demonstrated safe and effective electrode insertion. This minimally invasive technique ensured full tympanic scala insertion and satisfactory hearing rehabilitation.
Area of Science:
- Otolaryngology
- Robotic Surgery
- Biomedical Engineering
Background:
- Cochlear implantation is a crucial treatment for severe to profound hearing loss.
- Minimally invasive electrode insertion techniques are essential for preserving intracochlear structures.
- Robotic systems offer potential advantages in precision and stability for otological surgery.
Purpose of the Study:
- To evaluate the safety and efficacy of robot-assisted electrode insertion in cochlear implantation.
- To assess the outcomes of using the RobOtol system for cochlear implant surgery.
Main Methods:
- A case report detailing robot-assisted electrode insertion using the RobOtol system and a Nurotron slim electrode array (CS-10A TM).
- Analysis of robotic system preparation time, electrode insertion process, and intraoperative measurements.
- Evaluation of postoperative outcomes and hearing rehabilitation over a three-month follow-up period.
Main Results:
- Successful robot-assisted electrode insertion in an adult patient.
- The procedure involved a 6-minute preparation time for the robot system.
- The electrode array was inserted fully into the tympanic scala with no intraoperative damage, normal impedances, and satisfactory hearing outcomes post-implantation.
Conclusions:
- Otological robot systems enhance accuracy and reduce tremors during micromanipulation in cochlear implantation.
- Robot assistance enables safe, minimally invasive electrode insertion, ensuring full tympanic scala coverage.
- This technology aids in preserving delicate intracochlear structures and achieving good hearing rehabilitation.
