The Nucleus Contour electrode array can be safely implanted with modified surgical techniques. Careful adjustments to cochleostomy size and insertion method minimize basilar membrane trauma during cochlear implant surgery.

Area of Science:

  • Otolaryngology
  • Biomedical Engineering
  • Neurosurgery

Background:

  • The Nucleus perimodiolar Contour electrode array is a novel device for cochlear implantation.
  • Previous studies have established the safety of the Nucleus standard straight electrode array.

Purpose of the Study:

  • To compare the handling and insertion trauma of the Nucleus Contour electrode array versus the Nucleus standard straight electrode array in human temporal bones.

Main Methods:

  • Human temporal bones were implanted with electrode arrays by an experienced surgeon.
  • Radiological and histological evaluations were performed to assess trauma.

Main Results:

  • The standard straight array insertion was atraumatic.

  • Nucleus Contour array insertion caused basilar membrane penetration in some cases, particularly with standard cochleostomy techniques.
  • Modifying cochleostomy size and insertion technique reduced penetration rates to comparable levels with other designs.

    • Conclusions:

    • The Nucleus Contour electrode array design meets safety requirements for intracochlear use.
    • Modified surgical techniques, including cochleostomy adjustment and partial stylet withdrawal, are crucial for safe insertion.
