Contour Advance® Electrode

  • For Severe to Profound Hearing Loss

  • True innovation with the industry’s longest standing perimodiolar electrode 

  • Proven Perimodiolar Placement 

The Contour Advance gets you close to the hearing nerve through its unique stylet based design. With the Advance Off-Stylet® technique, you can achieve an insertion with minimal lateral wall trauma1 to maximize performance outcomes.2 Proximity to the spiral ganglion cell population has been proven to provide targeted stimulation and minimize physiological factors correlated to the distance from the modiolus.3,4

Key Features

  • Softip™ for minimal insertion trauma

  • White marker assists Advance Off–Stylet (AOS™) insertion

  • 22 half–banded platinum electrode contacts provide focused stimulation to the spiral ganglion cell region

Nucleus® Cochlear Implant Surgical Training Lab

Cochlear's desire to deliver superior outcomes has driven our approach for over 30 years. It is strengthened by our groundbreaking research, worldwide collaboration with surgeons, audiologists, leading scientists and engineers. The result is a market–leading portfolio of electrodes that favor a variation of surgical preferences to address the widest range of patient conditions. Each electrode is uniquely designed for preservation of delicate cochlear structures and to deliver the best possible hearing performance and outcomes. 

At Cochlear, we value our partnership with cochlear implant surgeons in changing the lives of people with hearing loss. We recognize the importance of continued collaboration, education and training. Therefore it is our pleasure to invite you to the temporal bone lab for a surgeon's training course. 

This full day, hands-on lab is designed for otolaryngologists new to cochlear implantation, or experienced implant physicians seeking an update. The course covers a range of surgical techniques for cochlear implantation specific to the Nucleus electrode portfolio. The program includes a combination of didactic sessions, interactive discussion, and hands-on drilling in the temporal bone lab. 

Course Curriculum

Topics covered: 

  • Temporal bone anatomy

  • Nucleus cochlear implant system

  • Nucleus templates and surgical instruments

  • Surgical steps of the cochlear implant procedure

  • Electrode array options

  • Candidacy

  • Imaging

  • Case scenarios 

  • Revisions, meningitis, cochlear abnormalities

Temporal bone dissection: 

  • Canal wall mastoidectomy

  • Facial recess

  • Cochleostomy and Round Window approaches

  • Electrode array insertion
