Objective: Prelingually deafened adults tend to demonstrate smaller im
provements in speech recognition after cochlear implantation than do p
ost-lingually deafened adults, which has led some professionals to bel
ieve that prelingually deafened adults receive only minimal benefit fr
om a cochlear implant. The primary objective of this study was to eval
uate cochlear implant use and satisfaction by prelingually deafened ad
ults. Design: A questionnaire was administered to 12 prelingually deaf
ened adult cochlear implant patients to evaluate cochlear implant effi
cacy and satisfaction. Questionnaire results were contrasted with perf
ormance on speech recognition tasks. Results: Although these patients
demonstrated little or no improvements in speech recognition 12 mo pos
toperatively, most patients reported that they used their device regul
arly, that they were satisfied with their device, and that using the c
ochlear implant improved both their expressive and receptive communica
tion skills. Conclusions: Procedures other than traditional speech rec
ognition measures should be used to evaluate cochlear implant benefit,
particularly with prelingually deafened adults.
