ObjectivesCochlear implant (CI) greatly enhances auditory performance as compared to hearing aids and has dramatically affected the educational and communication outcomes for profoundly deaf children. Universiti Kebangsaan Malaysia (UKM) pioneered CI program in 1995 in the South East Asia. We would like to report the long-term outcomes of UKM paediatric cochlear implantation in terms of: the proportion of children who were implanted and still using the device, the children's modes of communication, their educational placements, and their functional auditory/oral performance. We also examined the factors that affected the outcomes measured.Study designThis was a cross sectional observational study.MethodsTwo sets of questionnaires were given to 126 parents or primary caregivers of the implantees. The first set of questionnaire contained questions to assess the children's usage of CI, their types of education placement, and their modes of communication. The second set of questionnaire was the Parent's Evaluation Of Aural/Oral Performance of Children (PEACH) to evaluate the children's auditory functionality.ResultsOur study showed that among the implantees, 97.6% are still using their CI, 69.8% communicating orally, and 58.5% attending mainstream education. For implantees that use oral communication and attend mainstream education, their mean age of implantation is 38 months. This is significantly lower compared to the mean age of implantation of implantees that use non-oral communication and attend non-mainstream education. Simple logistic regression analysis shows age of implantation reliably predicts implantees (N = 126) would communicate using oral communication with odds ratio of 0.974, and also predict mainstream education (N = 118) with odds ratio of 0.967. The median score of PEACH rating scale is 87.5% in quiet, and this significantly correlates with an earlier age of implantation (r = −0.235 p = 0.048).ConclusionsUKM Cochlear Implant Program has achieved reasonable success among the pediatric implantees, with better outcomes seen in those implanted at the age of less than 4 years old.
