The Evaluation Of Auditory And Speech Abilities And Behavior Problems In Prelingually Deafed Children After Cochlear Implantation

Objectives:To observe the time regularity of auditory and speech rehabilitation and psychobehavioral development, by following part of prelingually deafed children who had underwent cochlear implantation in our hospital.Methods:62 prelingually deafed children were involved. Auditory and speech assessment was conducted with free-field audiometry, Meaningful Auditory Integration Scale or Infant-Toddler Meaningful Auditory Integration Scale (MAIS/IT-MAIS), Categories of Auditory Performance (CAP), Speech Intelligibility Rating (SIR). Achenbach’s child behavior checklist (CBCL) was employed to screen their behavior problems. Grouped according to the study factors and analyzed the results.Results:Cochlear implanted Children enhanced their auditory and speech ability as rehabilitation time increased. Significant differences were in MAIS/IT-MAIS, CAP and SIR between children having recovered for less than 2 years and 2 to 4 years(P<0.05), also in aided audiometric thresholds and SIR between children having recovered for 2 to 4 years and more than 4 years(P<0.05). Moreover,12 children got CBCL scores higher than the border. The behavior problems detection rate was 20%. In 6 to 11 years old children,"Aggressivity"arose most frequently among boys and "Depression" was among girls.Conclusions:Prelingually deafed children with cochlear implants display considerable and accordant auditory and speech ability growth over time. After recover for 4 years, their auditory ability reaches a platform while speech ability still advance. Children with cochlear implants are more likely to arise behavior problems even when they obtain good auditory and speech ability. They ought to be paid enough attention and correct guidance on psychobehavioral development.
