Background and Objectives：The aims of this study were 1) to assess the development of open-set speech perception in pre-lingualy deaf children who had multichannel cochlear implants implanted and 2) to document the outcomes according to age at implantation and the device type. Subjects and Method：received a Nucleus 22 or Nucleus 24 multichannel cochlear implants and who had been followed-up for a period of 1-4 years at Dong-A University Hospital. They had no other disabilities. Open-set speech perception was evaluated pre-operatively, postope-ratively for 6 months and then on a yearly basis using the following assesment materials：Phonetically Balanced Kindergarten monosyllabic word lists, bisyllabic word lists, and Glendonald Auditory Screning Procedure(GASP) sentence subtest. Paired t-diferences in the mean scores between two groups divided by age at implantation and the device type. Results：Open-set speech perception for all subjects was improved to mean 84% for monosylabic phonemes and 89% and 88% for bisyllabic phonemes and everyday sentences respectively at 4 years postimplantation. Open-set speech perception ability was better for children who received implantation before 5 years of age than those who did it after 5 years of age at 3 years interval and 4 years interval. Conclusion：The prelingualy deaf children in our study showed significant open-set speech perception abilities at the time of the last postoperative evaluation. Rapid improvement was noted in open-set spech perception for the children who had Nucleus 24M implanted before 5 years of age. In order to maximize the effects of access to auditory stimuli provided by the cochlear implant on the development of open-set speech perception, a structured postoperative schedule of programing and rehabili-tation is recomended in addition to the optimal educational environment.
