Official Title

The Performance of a Robot-assisted Minimally Invasive Direct Cochlear Access for Cochlear Implantation

Brief Summary

      The cochlear implant is a neural prosthesis and has been the gold standard treatment for
      severe to profound sensorineural hearing loss over several decades. The surgical procedure
      for cochlear implantation aims to atraumatically insert the electrode array of the cochlear
      implant into the cochlea. However, due to the location of the cochlea inside the skull, the
      surgeon is required to create an access from the surface of the temporal bone to the cochlea
      (inner ear). In conventional methods, this access is acquired by removal of portions of the
      mastoid bone through a mastoidectomy and posterior tympanotomy. The outcome and success of
      the conventional procedure varies due to mainly two factors: surgeon skill and subject
      anatomical variation. To overcome these variables toward a more consistent and less invasive
      cochlear implantation surgery, the development of robotic and image guided cochlear
      implantation has taken place. This study primarily aims to explore the performance of robotic
      cochlear implantation surgery.
