Summary
Robotic-assisted cochlear implantation combined with cochlear microphonic potential (CMP) monitoring shows feasibility. This approach may enhance cochlear structure preservation during electrode insertion.
Area of Science:
- Otoacoustic Emissions
- Neurosurgery
- Biomedical Engineering
Background:
- Cochlear microphonic potentials (CMPs) reflect hair cell activity and can monitor hearing during cochlear implantation.
- Slow electrode insertion is crucial for preserving cochlear structures.
Purpose of the Study:
- To evaluate the feasibility of combining robotic-assisted cochlear implant (CI) electrode insertion with real-time CMP monitoring.
- To assess the potential of this combined approach for improving cochlear structure preservation.
Main Methods:
- A 5-degree-of-freedom robotic manipulator was used to guide electrode insertion trajectory.
- Cochlear microphonic potentials (CMPs) were recorded via the CI electrode at various insertion stages.
- Acoustic pure tones, tailored to patient hearing status, were used as stimuli.
Main Results:
- Human-guided robotic CI electrode insertion with simultaneous CMP measurement was demonstrated as feasible.
- The combined approach allows for real-time monitoring and potential trajectory adjustments based on CMP feedback.
- Initial experiences suggest this method is a promising strategy for cochlear structure preservation.
Conclusions:
- Robotic-assisted CI insertion coupled with CMP monitoring is a viable technique.
- This integrated method offers a promising avenue for enhancing surgical outcomes and protecting inner ear structures during implantation.
