Study And Application Of Hearing Rehabilication Evaluation Criteria For Cochlear Implant Children

It’s very important to observe hearing and speech&language ability, to track rehabilitation and compare the performance of different types of artificial cochlea that establishing hearing evaluation indexes for cochlear implantation children. To Standardize vowel, consonant, monosyllable, disyllable, phrase and sentence indexes when using assessment standards and methods for Hearing impaired children’s auditory and speech&language ability in our study. On the same time, using the six indexes to track one-year rehabilitation for cochlear implantation childrenThe following are the contents and results of our study:1. To Standardize Vowel, consonant, monosyllable, disyllable, phrase and sentence indexes by evaluating normal hearing children(1) The evaluation criteria of the vowel, consonant, tonal, monosyllabic Word, two-syllable words and phrase recognition for cochlear implant children over3years old are revised.(2) The evaluation criteria of the vowel, consonant, tonal, monosyllabic Word, two-syllable words and phrase recognition for cochlear implant children of2years old are developed.2. To dissuss the feature of auditory of cochlear implant children when using the six indexes to evaluate their auditory in one-year auditory training.(1) The traing time is longer, thescore of the vowel, consonant, tonal, monosyllabic Word, two-syllable words and phrase recognition are higher. The standards are adapt to evaluate auditory rehabilitation of cochlear implant children.(2) Cochlear implants younger, rapid development are got. Cochlear implants younger, growth are larger. The training time of CI children for vowel, monosyllable, disyllable rehabilitation are at least one year, but for small-age children, the time are exceed one year. And for consonant and phrase and sentence perception, the time are all exceed one year. (3) First6months are a critical period of hearing development for cochlear implantation children, during this period, it’s essential to debugging, optimization of cochlear. So we must finish debugging, optimization of implanted cochlear.(4) Age and rehabilitation time are the important factors to influence the increasing degree of vowel, consonant, monosyllable, disyllable, phrase and sentence. The increasing degree of small-age teams are higher than old-age children. With the progress of rehabilitation, the growth rate in different rehabilitation periods reduced one by one.
