Abstract:
Objective To observe the effects of rehabilitation in the 55 prelingually deaf pediatric cases for two years after cochlear implantation ,factors including cochlear implantation and recovery time ;to compare the re-covery effects in the group of 1 to 3 years old children with the group of 3~5 years old (including the age of 3 years old) who lost their hearing before learning to speak ,and to provide clinical evidence for providing cochlear implant therapy to the prelingually deaf children as early as possible .Methods A total of 55 pediatric relingually deaf cases were included in this study .According to their implantation time and application duration ,they were divided into 2 groups :1 to 3 years old group (32 cases) ,and >3 to 5 years old group (23 cases) respectively .The hearing ,lan-guage and learning abilities on 1 ,3 ,6 ,12 ,18 ,24 months after cochlear implantation were evaluated ,using statisti-cal method to record CAP and SIR scores .Results The rehabilitation effects ,the average ages ,CAP ,speech rec-ognition rates and SIR were increased two years afterwards .The effects of younger age group were more noticeable than that in the older group .The differences between the two groups were statistically significant (P<0 .05) .Av-erage speech recognition rates ,average speech rehabilitation effects in each postoperative period of younger age group were better than those of in older age group ,showing significant differences (P<0 .05);CAPs in the younger age group on 1 ,3 and 12 months after CI surgery were significantly higher than those of in the older group (P value were 0 .001 ,0 .001 and 0 .002 ,respectively) .SIR in the younger age group at the time of 1 ,3 ,12 ,24 months were significantly higher than those of in the older group(P values were 0 .00 ,0 .00 ,0 .00 and 0 .024 ,respectively) . Conclusion Implanted age and recovery time are the key factors that influence the effects of postoperative rehabilita-tion .The younger when the children get cochlear implantation and the longer the recovery time takes during two years after cochlear implantation ,the better the results are .The standardization of domestic assessment for the re-covery effects and the international evaluation method have a certain degree of equivalence .
