Brief Summary:
To assess the feasibility of achieving a minimally invasive access to the inner ear through the navigation-based HEARO procedure and subsequently insert the electrode array of the cochlear implant through the access.

Condition or disease Intervention/treatment Phase
Sensorineural Hearing Loss Device: HEARO Not Applicable

Detailed Description:
  • Demonstrate the feasibility and efficacy of performing a middle and inner ear access for cochlear implantation procedures in adults.
  • Validate the procedure workflow including imaging, planning, safety assessment, image to patient registration, robotic drilling, electrode insertion and device implantation.
  • Validate the system and procedure safety mechanisms.
  • Collect required data for validation of safety algorithms and procedure workflow optimisation.
  • Validate the HEARO system.

Arm Intervention/treatment
Experimental: Minimally invasive robotic cochlear implantation with HEARO Device: HEARO
Robotic system for otological procedures
Other Name: HEARO procedure

Primary Outcome Measures :
  1. The relative ratio of successfully completed procedures where a direct access tunnel was drilled to the cochlea with the HEARO® system and the electrode was conventionally inserted through the tunnel. [ Time Frame: Image data aquired during the procedure ]

Secondary Outcome Measures :
  1. Number of completed middle ear access [ Time Frame: The procedure (day 0) ]
  2. Number of completed inner ear access [ Time Frame: The procedure (day 0) ]
  3. Accuracy of the drilled trajectory [ Time Frame: Image data aquired during the procedure ]
  4. Sensitivity and specificity of facial nerve monitoring [ Time Frame: The procedure (day 0) ]
  5. Measurement of the insertion angle [ Time Frame: Image data aquired during the procedure ]
    Measurement of the insertion depth of the electrode into the Cochlea

  6. Number of tip fold-overs [ Time Frame: The procedure (day 0) ]
  7. Number of Scala deviations [ Time Frame: The procedure (day 0) ]
  8. Number of complication events on (temporary) facial nerve palsy, pre and post bleeding and infection [ Time Frame: day 0-30 ]
  9. Time of procedure [ Time Frame: The procedure (day 0) ]
  10. Volume of tissue removed [ Time Frame: Image data aquired during the procedure ]
