Objective: To report early postimplantation speech recognition results in children who received Nucleus CI24M cochlear implants.
Study design: The study group consisted of 19 consecutively implanted children.
Patients and setting: Congenitally deaf children (20 months to 15 years old) were implanted with the Nucleus CI24M and followed-up at New York University Medical Center for a period of 3 to 12 months.
Main outcome measures: Speech perception was evaluated preoperatively and postoperatively using the Early Speech Perception (ESP) test, the Glendonald Auditory Screening Procedure (GASP) word and sentence tests, Phonetically Balanced Kindergarten (PBK) monosyllabic word lists, Common Phrases test, the Multisyllabic and Lexical Neighborhood (MLNT, LNT) tests, and the Banford-Kowal-Bench (BKB) sentence test.
Results: One-way analyses of variance revealed significant improvement in open-set speech recognition in children able to perform measurement tasks.
Conclusions: The Nucleus CI24M cochlear implant provides significant benefit to children after short-term use.
