The purpose of the study was to analyze changes in neural response telemetry using the Cochlear Nucleus 24 Contour before and after stylet removal in a human model.
Prospective study.
Tertiary referral center.
Twelve patients (23-72 years old) undergoing cochlear implantation, using the Nucleus 24 Contour implant, secondary to congenital and age-related hearing loss.
Cochlear implantation with Cochlear Nucleus 24 Contour implant.
Neural response telemetry thresholds were recorded initially with the stylet in and then with the stylet out during the implant procedure.
Stimulus levels to obtain neural response telemetry threshold after stylet removal were statistically lower after the stylet was removed.
The Nucleus 24 Contour achieves a perimodiolar position once the stylet is removed, and this leads to reduction in the current required to elicit a threshold neural response telemetry response.
