Auditory rehabilitation on congenital deafness pediatric patients after cochlear implantation

Purpose: This study aimed to determine the effect of auditory rehabilitation in children after 1 year of cochlear implantation and related factors. Method: Retrospective and prospective descriptive study was conducted at the Ho Chi Minh City Ear-Nose-Throat Hospital from January 2018 to April 2020. Determine the effect of auditory rehabilitation in children according to the CAP scale at 3, 6, 9 and 12 months after implant activation. Result: Thirty-nine children with congenital deafness who received cochlear implants were included in this study. At 1 year after CI, all children reached the CAP score at 5 points or more and 87.18% of cases had CAP score from 6 to 7 points. The mean CAP scores at 12 months after CI were 6.18 +/- 0.64 points. This study found out the effects of number of CI, time of learning auditory rehabilitation and family cooperation on CI outcome. Children with bilateral CI were more successful in auditory performance than children with unilateral CI (mean CAP scores: 6.38 +/- 0.62 vs 6.04 +/- 0.64). In the group of children with cooperative parents, children who studied at class for "5 hours per week or more" had better auditory rehabilitation than those who studied for fewer hours (mean CAP scores: 6.25 +/- 0.64 vs. 6.20 +/- 0.68). Conclusion: CAP score of pediatric patients tend to increase significantly one year after the operation, almost reach the normal score.
