Perceptual and production abilities in profoundly deaf children with multichannel cochlear implants.

A total of 218 children have been implanted to date with the Nucleus multichannel cochlear implant. All children have stimulated and there have been only 6 complications that required subsequent surgical intervention. After 12 months of experience with the device, significant improvements in auditory-alone speech perception were demonstrated by 66 percent of subjects tested on prosodic and closed-set measures and by 46 percent of subjects tested for open-set word recognition.
