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.
Course created on January 9, 2020
- After 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.
- After 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.
- After 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.

René H. Gifford, Ph.D., CCC-A, is a professor in the Department of Hearing and Speech Sciences with a joint appointment in the Department of Otolaryngology. She is currently the Director of the Cochlear Implant Program at the Vanderbilt Bill Wilkerson Center as well as the Associate Director of Implantable Hearing Technologies. Her current research interests include combined electric and acoustic stimulation (EAS) with cochlear implantation, hearing preservation with cochlear implantation, preoperative prediction of postoperative outcomes with implants, speech perception for adults and children with cochlear implants, and spatial hearing abilities of individuals with unilateral and bilateral cochlear implants. Dr. Gifford has published over eighty peer-reviewed articles and book chapters, and she authored a book in 2013 entitled “Cochlear Implant Patient Assessment: Evaluation of Candidacy, Performance, and Outcomes.”
Sponsor Disclosure: This Course is presented by Cochlear Americas in partnership with AudiologyOnline.
Content Disclosure: This learning event focuses on the following specific products or services: straight electrode arrays and precurved electrode arrays (though all manufacturers are included, two of the studies discussed only included Cochlear devices; but those studies were not funded by Cochlear)
