Benefits Afforded by Precurved Electrode Arrays: Speech and Auditory Perception for Adult Cochlear Implant Recipients

Course: #34111Level: Advanced1 Hour 28 Reviews
Recorded Webinar

More effective cochlear implant (CI) clinical practices could result from consideration of individualized electrode array type (precurved vs. straight) as well as individual electrode position, resultant auditory perception, and device wear time in an attempt to maximize the number of spatially selective channels and auditory outcomes for each listener. This course will cover recent research completed at Vanderbilt University Medical Center combining audiological assessment, image processing, and application of individualized programming aimed at improving outcomes for adult CI recipients.

Learning Outcomes

  • checkmarkAfter this course learners will be able to describe expected CI outcomes by a large clinical population without knowledge of electrode location and device wear time and compare this broad range of variability to what we could expect with more knowledge of individualized variables.
  • checkmarkAfter this course learners will be able to describe differences between classic literature and newer studies providing evidence for greater channel specificity in modern-day CI recipients with precurved electrode arrays localized in scala tympani.
  • checkmarkAfter this course learners will be able to describe the potential beneficial effects of a well-placed precurved electrode array (such as CI632) on upper stimulation levels, spectral resolution, and speech recognition in quiet and noise.
