Summary
This study introduces a novel, repositionable microstereotactic frame for cochlear access, improving surgical precision and reducing delays. The new frame offers enhanced accuracy, minimizing risks associated with delicate neurovascular structures during surgery.
Area of Science:
- Neurosurgery
- Medical Robotics
- Otolaryngology
Background:
- Cochlear access involves risks due to proximity of nerves and blood vessels.
- Current microstereotactic frames cause clinical workflow disruptions and manufacturing delays.
- Existing frames rely heavily on surgeon skill and hand-eye coordination.
Purpose of the Study:
- To develop and evaluate a novel, repositionable microstereotactic frame for image-guided cochlear access.
- To overcome the manufacturing delays and infrastructure requirements of current systems.
- To improve the safety and efficiency of cochlear surgical procedures.
Main Methods:
- Design and construction of an automated, image-guided, repositionable microstereotactic frame.
- Phantom testing using human clinical trajectory data to assess accuracy.
- Cadaver experiments to evaluate the complete image-guided surgery pipeline.
Main Results:
- Mean accuracy at the cochlea of 0.20 ± 0.07 mm in phantom testing.
- Accuracy of 0.38 mm achieved at the cochlea in a cadaver experiment.
- Demonstrated feasibility of the repositionable frame, reducing workflow disruption.
Conclusions:
- The novel repositionable microstereotactic frame significantly enhances precision for cochlear access.
- This system obviates the need for lengthy manufacturing delays and specialized infrastructure.
- The technology shows promise for safer, more efficient image-guided cochlear surgeries.
