Effectiveness of CI in prelingually deafened adults

Johan Frijns

The results obtained with cochlear implants have gradually improved over the years. The current expectation for a postlingually deafened adult CI recipient is that a conversation without visual cues is possible in a quiet surrounding. Due to these improvements of CI, the question arises whether an implant could also be beneficial for groups of patients that traditionally were excluded, for instance for prelingually deafened adults. Research in this area has shown that a candidate’s oral language development is a much better predictor for the outcome with CI than the pre-operative speech understanding with hearing aids. Speech production turned out to be a reliable predictor for the ability to use the auditory information offered by the cochlear implant. This project investigates the effectiveness of a CI for this group of patients as well as new criteria for implantation.
