Optimising Surgical Care

We understand the importance of your role in delivering the best possible hearing outcomes to your patients. That’s why we continue to pioneer new technology and develop solutions to improve the surgical experience for you and your patients.

Our Surgical Care solutions are designed to enhance patient outcomes through intraoperative tools and insights. With increased confidence in device placement, surgical outcomes and postoperative clinical performance may also be optimised.

The Nucleus® SmartNav System

The award-winning Nucleus SmartNav System provides wireless, real-time, actionable insights to support navigation during cochlear implant surgery, delivering added assurance that surgery was successful, and the electrode was properly placed.1

This iPad-based solution and surgical processor provide an intuitive workflow to help you in surgery, giving you real-time feedback for in-theatre decision-making around angular depth and the consistency of insertion.2-7

Wireless connectivity, digital implant registration, and intuitive design deliver a more seamless workflow in the operating room.8

Data can then be directly imported into Custom Sound® Pro fitting software to support MAP creation.9

Nucleus SmartNav intraoperative measures:

  • Placement check – provides valuable information on final electrode placement and is designed to reduce the need for intraoperative imaging post electrode insertion.8,10-12
  • Angular insertion depth – provides real-time measurement of angular insertion depth and final electrode position.*,5-6
  • Time of insertion (per electrode) – provides feedback on consistency of the electrode insertion.8
  • Impedance – provides assurance that the device is operating as intended, prior to leaving the operating room.8,13
  • Advanced and AutoNRT® measurements – the option to use Advanced NRT for obtaining neural response telemetry thresholds, providing flexibility in settings for optimal measurement.8,13
  • Electrical Stapedius Reflex Threshold (eSRT) – confirms nerve response to electrical stimulation.8,14
