Objective:The purpose of this study is to investigate the effect of cochlear implantation on the hearing and speech rehabilitation of pre-lingual deaf children. Method: This study selected 80 children with pre-lingual deafness who were treated by China Hearing and Language Rehabilitation Research Center from January 2015 to 2018 as subjects. All the children were diagnosed to meet the standard of cochlear implantation, and their mother tongue was Putonghua. After completion of treatment, the changes of SIR and CAP scores with rehabilitation time were compared and analyzed. Result: There was a significant positive correlation between IT-MAIS/MAIS score probability and CAP score. (r=0.485,P＜0.05). Rehabilitation effect of two groups of children was consistent, and there were similarities in the interpretation of rehabilitation effect. However, the difference between CAP scores was large, and the occurrence of this result may be related to parents'judgment. Conclusion: Rehabilitation of pre-lingual deaf children after cochlear implantation is a complex and long-term training process, which requires long-term follow-up of relevant personnel in many aspects to obtain the results that meet the law of auditory and speech development.
