Objectives:To determine the efficacy of cochlear implantation (CI) in prelingually deafened adolescent children and to evaluate predictive variables for successful outcomes.Design: Retrospective medical record review.Participants: Children aged 10 to 17 years with prelingual hearing loss (mean length of deafness, 11.5 years) who received a unilateral CI (mean age at CI, 12.9 years).Intervention: Unilateral CI.
Main Outcome Measures: Standard speech perception testing (Consonant-Nucleus-Consonant [CNC]monosyllabic word test and Hearing in Noise [HINT] sentence test) was performed preoperatively, 1 year postoperatively (year 1), and at the last follow-up/end of the study (EOS).Results: There was a highly significant improvement in speech perception scores for both HINT sentence and CNC word testing from the preoperative testing to year For editorial comment see page 93
