    Direct Cochlear Access (DCA) offers a highly accurate alternative to mastoidectomy for electrode insertion. This novel system enhances safety and precision in cochlear implant procedures.

    Area of Science:

    • Neurosurgery
    • Otolaryngology
    • Medical Device Engineering

    Background:

    • Traditional mastoidectomy for cochlear implantation is invasive.
    • Existing methods for electrode insertion face accuracy and safety challenges.

    Purpose of the Study:

    • To introduce and evaluate a novel Direct Cochlear Access (DCA) system.
    • To assess the accuracy and safety of DCA for cochlear electrode insertion.

    Main Methods:

    • Development of a high-accuracy system for creating a small diameter tunnel to the cochlea.
    • Integration of multiple safety sub-systems into the DCA approach.
    • Evaluation of the system's accuracy in a cadaver model over two years.

  • The DCA system achieved unprecedented high accuracy in cadaveric trials.
  • The system incorporates several safety sub-systems to mitigate risks.
  • Consistent accuracy was demonstrated over a two-year evaluation period.

    • Conclusions:

    • Direct Cochlear Access (DCA) presents a viable and highly accurate alternative to standard mastoidectomy.
    • The developed DCA system offers enhanced safety features for cochlear electrode insertion.
    • Further clinical application of DCA holds promise for improving cochlear implant surgery.
