There is no arm to this study--(each participant serves ashis or her own control). Blinding or masking procedures are not included in the design, as it is not possible to conceal the presence or absence of a cochlear implant from device recipients and/or clinical investigators.
Device: Iowa/Nucleus 10/10 mm and Freedom Cochlear Implantation
Participants will receive one standard Nucleus Freedom electrode array and an Iowa/Nucleus 10/10 mm electrode array on the contralateral side.
- Pre-school Language Test [ Time Frame: 48 months ]Assesses global language skills using toys and pictures. This test assess auditory comprehension and expressive communication and a total language score is calculated. The reported score was assessed at 48 months post-implantation. The total language standard score ranges from 50-150. A higher total score indicates better performance. A raw score for total language is calculated and converted into a standard score.
- Phonemically Balanced-Kindergarten Test (PB-K)-Bilateral [ Time Frame: 56 months ]PB-K Test was constructed to be an open-set test of word understanding for children. It is scored as a percentage of words correct. The test was measured using the Iowa/Nucleus 10/10 mm and Nucleus Freedom together, the Iowa/Nucleus 10/10 mm only, and the Nucleus Freedom electrode only conditions. The higher the score, the better the word understanding. The post-operative time point for this score was reported on average at 56 months post-implantation.
