인공와우는 청각장애 아동들의 말-언어 습득을 위한 효과적인 재활수단으로 널리 알려져 있다.18) 우리나라의 경우 2005년 1월 인공와우 이식술(cochlear implantation)이 건강보험의 적용을 받으면서 평균청력(4분법)이 90 dB HL 이상인 선천성 청각장애 학생이 학령기에 인공와우 수술을 받는 사례가 늘어나고 있고, 재활 및 교육에 있어서도 큰 변화를 가져왔다. 그리고 2009년 9월에는 분실 등으로 인해
The present study examined auditory performance before and after cochlear implantation in three school-aged children with hearing and listening tests in order to investigate factors affecting auditory performance after cochlear implantation and the importance of auditory rehabilitation. After cochlear implantation, subject 1 had better auditory performance than subjects 1 and 2 to some extent afterwards. In particular listening tests of one syllable (36%) and two syllables (52%) with auditory-only (AO) word tests for subject 1 were better than subject 2 (16%, 24%) and subject 3 (24%, 8%) respectively. The reasons for good auditory performance in subject 1 were as follows. Subject 1 already had good auditory performance before cochlear implantation, and had received aural rehabilitation for a longer period (4 years six months) than subjects 2 and 3 (2 years eight and ten months). The age of cochlear implantation in subject 1 was earlier than subject 2 and subject 3. The results of this study suggested that school-aged children with cochlear implants should receive auditory rehabilitation including auditory training continuously in order to train their residual hearing and adjust themselves to the cochlear implant. and psycho-social counseling and hearing-related information should be provided to their families, friends and teachers.
