In this investigation we measured the performance of 50 prelingually deaf children on several speech perception tests. Children were from 2 to 15 years of age, and some children were tested with as much as 5 years of cochlear implant use. Speech perception tests included the recognition of stress pattern, consonants, vowels, words, and sentences. The(More)
This study focused on long-term speech perception performances of 34 prelingually deafened children who received multichannel cochlear implants manufactured by Cochlear Corporation. The children were grouped by the age at which they received cochlear implants and were characterized by the amount of time they used their device per day. A variety of speech(More)
Studies documenting subjective changes in quality of life of pediatric cochlear implant recipients are limited. In this study, parents of cochlear implant recipients completed a questionnaire requesting them to list advantages and disadvantages associated with their children's cochlear implant use. Preimplantation, benefits expected by parents included(More)
Electrically evoked auditory brain stem responses (EABR) were measured in 12 adults and 14 children with the Nucleus cochlear implant. Measures were made both intraoperatively and several months following surgery. EABR thresholds were consistently greater than clinically determined measures of behavioral threshold (T-level) but less than maximum comfort(More)
The speech perception performance of 10 congenitally deaf and 3 postlingually deafened children who received the Cochlear Corporation multichannel cochlear implant was examined and compared. The children were tested preimplant and at 6-month intervals up to 2 years using the Monosyllable-Trochee-Spondee test (MTS), the Word Intelligibility by Picture(More)
An open-ended questionnaire was administered to 53 of some of the better patients using five different kinds of cochlear implants. The subjects listed the advantages and disadvantages of their cochlear implant. Patients were asked about the time from implantation until maximum benefit and effect of the cochlear implant on tinnitus. Advantages were reported(More)
OBJECTIVE To examine whether children perform better when they receive cochlear implants when they are 2 to 4 years of age than when they are older, and to determine whether 4-year performance can be predicted from 1-year results. METHOD Children in two age groups (2 to 4, 4 to 9 years) were tested for performance, and the age groups were compared.(More)
We review recent data from the University of Iowa obtained from prelingually deaf children over 3 years using feature-extraction versions of the Nucleus cochlear implant, and from postlingually deaf adults using the compressed-analog Ineraid, a feature-extraction version of Nucleus, and a continuous interleaved sampling version of the Clarion cochlear(More)
