Abstract

The Research on Sensory and Communicative Disorders (RSCD) was originally planned as a nationwide research project to assess the effectiveness of interventional methods for hearing-impaired children. Of the 638 hearing-impaired children who participated in the RSCD project in 2009, 282 (44.2%) were cochlear implant users. Of these, 196 (69.5%) were both cochlear implant plus hearing aid (bimodal stimulation) users, 84 (29.8%) were unilateral-cochlear implant only users, and 2 children (0.7%) were bilateral cochlear implant users.<br>The average hearing loss level was 109.7dB. However, good outcomes of the hearing threshold (35.9dB) and maximum speech discrimination score (80.3%) were observed. A high correlation (r=0.52) was found between the age at cochlear implantation and the maximum speech discrimination score. The scores on the speech and language tests in the children who were under 24 months of age at the time of the cochlear implant surgery were better than those in the children who were over 24 months of age at the time of the surgery. The results of our study indicate that early implantation is beneficial for speech and language development.
