“…However, not all studies showed a negative correlation between the age at implantation and the language outcomes. In a series of comprehensive studies involving 181 prelingually deaf children with cochlear implants, Geers and colleagues failed to find a significant effect of age at implantation on both speech perception and speech production abilities of the children [14][15][16]. Note that a vast majority of the 181 children received cochlear implantation at the ages of 2 -4 years old.…”

Objective: The purpose of the present study was to investigate the tone production performance of native Mandarin Chinese speaking children with cochlear implants and to evaluate the effects of age at implantation and duration of implant use on tone production in those children. Methods:Fourteen prelingually deaf children who had received cochlear implantation and 14 agematched normal-hearing children participated in the study. Both groups were of native Mandarin Chinese speaking children. One hundred and sixty tone tokens were recorded from each of the children. The total of 4480 tokens (160 × 28) were then used in tone perception tests in which seven normal-hearing native Mandarin Chinese speaking adults participated.Results-The tone production of the cochlear implant children showed tremendous individual variability. The group mean performance was 48.4% correct, statistically significantly lower than the group mean performance of 78.0% correct in the normal-hearing controls. The tone confusion matrix analysis revealed that the production of Mandarin tone 2 (the rising tone) was most severely impaired in the cochlear implant children, followed by tone 3 (the low and dipping tone) and tone 4 (the falling tone). The most frequently perceived tone irrespective of the target tone was tone 1 (the high level tone). The tone production performance was negatively correlated with the age at implantation and positively correlated with the duration of implant use. Conclusions:There is a remarkable deficit in tone production in a majority of native tone language speaking, prelingually deaf children who have received cochlear implants. While an increased duration of implant use might facilitate tone production, the age at implantation appears to have a negative effect on tone production in cochlear implant children. Therefore, early implantation might be beneficial to tone production in prelingually deaf children whose native language is a tone language.Keywords cochlear implant; tone production; pediatric; tone language; Mandarin Chinese * Corresponding author.

In a preliminary report, we showed that prelingually deafened native Mandarin speaking children who had received cochlear implants demonstrated various degrees of deficits in tone production [4]. Peng et al. (2004) also reported that a majority of their 30 prelingually deaf children with cochlear implants did not master Mandarin tone production [5].

“…This could be inferred from the findings that speech production skills gradually increase with CI experience. Children in this study were achieving articulation proficiencies consistent with much older CI participants with similar amounts of CI experience [6] , and their performance was within 1.5 SD of their normal hearing peers on standardized tests of articulation and receptive vocabulary.…”

The communication modalities used, and the articulation and aural-only receptive vocabulary skills were investigated in 19 prelingually profoundly deaf infants who initially utilized Total Communication and who were implanted between the ages of 12 and 29m. Results revealed the children overwhelmingly tended to use voice only modality for an expressive task. Additionally articulation and receptive vocabulary skills approached those of normal hearing peers. Implications of these findings and suggestions for future studies are provided.

“…Not only in South Africa, but all over the world many areas of healthcare are replete with evidence of socioeconomic status and ethnicity related disparities, with pediatric cochlear implantation being no exception [75][76][77]. The current study population consisted of predominantly Caucasian (62%) children from the private health care system (95%), speaking either Afrikaans (46%) or English (43%).…”

Objective: To identify and describe predictors of pediatric cochlear implantation outcomes in a South African population. Methods:A retrospective study of 301 pediatric CI recipients from five cochlear implant programs was conducted and cross-sectional outcome data were added at the time of data collection. Twenty potential prognostic factors were identified from the retrospective dataset, including biographical, cochlear implant (CI), family and risk factors. Multiple regression analyses was performed to identify predictor variables that influence outcomes in terms of auditory performance (CAP scores), speech production (SIR scores), communication mode and educational placement.Results: Although implanted children within this sample did not have equal opportunity to access a second implant, bilateral implantation was strongly predictive of better auditory performance and speech production scores, an oral mode of communication and mainstream education. NICU admittance/ prematurity were associated with poorer auditory performance and speech production scores, together with a higher probability for non-oral communication and non-mainstream education. The presence of one or more additional developmental 2 condition was predictive of poorer outcomes in terms of speech production and educational placement, while a delay between diagnosis and implantation of more than one year was also related to non-mainstream education. Ethnicities other than Caucasian were predictive of poorer auditory performance scores and a lower probability for mainstream education.Conclusion: An extensive range of prognostic indicators were identified for pediatric CI outcomes in South Africa. These predictive factors of better and poorer outcomes should guide pediatric CI services to promote optimal outcomes and assist professionals in providing evidence-based informational counselling.
