C026 Speech perception and speech intelligibility in children after cochlear implantation in different age groups
Abstracts, ESPCI 2011 / International Journal of Pediatric Otorhinolaryngology 75 (2011) 33–57
The test was performed at first fitting of the speech processor and at each follow up visit. The psychometric properties of the Polish LittlEARS in CI children were evaluated with SPSS version 16.0. Results: The mean values (difficulty indexes) of the answers to the questions at first distribution of the questionnaire range from 0.01 to 0.62. The obtained values of corrected item-total correlations range from 0.10 to 0.73. The Cronbach’s alpha coefficient value is 0.94, indicating that the answerers are highly consistent. Conclusion: The results support the use of LittlEARS questionnaire in cochlear implanted children as a sensitive and reliable tool to monitor the benefit from new device.

Cl´ınica Universidad de Navarra. Pamplona, Spain Aim: Study the benefits of bilateral stimulation in sequentially implanted children. Material and Methods: 130 children received sequential bilateral CI. From this group, we selected a group of 42 children that were bilaterally CI users for more than 5 years. The mean age of the first implantation was 2.18 and 6.96 years for the second. Audiological test were used in quiet and noise enviroment. We have analized by separately the benefits obteined with the first and the second CI, and the binaural benefit with the use of both CI. Results: There are statistcally significative diferences between the first ear and the second one, regarding hearing improvement and word discrimination. In any condition studied, the results with two CI are significatively better than using a CI alone. Conclusion: In the studied population, the re-establishment of binaurality, gives better results than any unilateral condition, specially in noisy enviroments. C023 Accessing performance of Cochlear Implantation in young children in a developing economy – India S. Narang. Listen and Speak, Centre for children with Hearing Impairment, New Delhi, India Aim: This study examined the happiness quotient for children implanted with Neurelec Digisonic® SP cochlear implants. Social mainstreaming and scholar integration were investigated, in a developing economy context with limited resource and facilities. Material and Methods: This study examined twenty children between four and fourteen years-old from different parts of India, speaking different languages. It included questionnaires, tests and parents interviews. All these children had started using spoken language and had undergone Auditory Verbal Therapy. Results: The children and parents reported a significant happiness in the family and in the child’s life, which included an improved quality of life for all family members. Conclusions: Several children moved on to normal school, with some of them doing exceptionally well in their academics and some in music. The study does not conclude whether implantation has put new confidence into these children which probably would take them to develop high earning capabilities in future.

Material and Methods: About 30 children were included, all bilaterally implanted between ten months and five years. Children were evaluated post-implantation using age-appropriate test material for hearing in noise ability with a fixed level of noise and spatially separated from speech source. Localisation skills were also monitored. Results: Good results were observed in all cases, including localisation abilities for some children. Some issues in accepting the second device were observed in case of sequential implantation. Conclusions: Paediatric bilateral implantation shows very encouraging results, in terms of speech reception in noise and sound localization, even for very young patients. These results suggest that bilateral stimulation is an asset children hearing development, and that this practice will expand in the future. However, a prospective study with a control group could confirm these encouraging results. C025 Cochlear implanted children outperform Specific language impaired peers on verbal morphology A.

Govaerts3 . 1 Vrije Universiteit Amsterdam, Amsterdam, The Netherlands; 2 Leiden Centre for Linguistics, Leiden University, Leiden, The Netherlands; 3 The Eargroup, Antwerp-Deurne, Belgium Aim: To compare Cochlear Implanted (CI) and Specific Language Impaired (SLI) children on their language development (MLU, Mean Length of Utterance) and verb morphology (finite verb and agreement morpheme production). Materials and Methods: Spontaneous language samples were recorded from Dutch monolingual CI- children (N = 48) and SLIchildren (N = 38), aged 4 to 7. Outcomes were compared to those from Typically Developing (TD) hearing children. Results: At age 5 and 6, CI-children produce significantly more finite verbs than their SLI-peers. In 73% of the SLI-children the combined variable MLU*finite verb morphology yields outcomes that are significantly below age expectations as opposed to only 38% of the CI-children. Both clinical groups produced significantly more verbal agreement errors than TD-peers. Conclusion: CI-children outperform SLI-children on finite verb morphology. Only a subgroup of CI-children have a grammatical profile which is similar to the one found in SLI-children. Nevertheless, target-like verbal agreement remains difficult for CI-children.

Materials and Methods: 262 prelingual deaf children in equal boys and girls groups were enrolled. They were evaluated before implantation and 12months after device switch on. Auditory and speech conceptions were evaluated by means of CAP and SIR. Results: The mean CAP score after surgery for 1+ group was 5.17±1.45, in 2+ group was 4.56±1.92, in 3+ group was 4.38±2.02, in 4+ group was 4.36±2.31 and in 5+ group was 4.31±1.38. The mean SIR score after surgery for those groups were consequently: 2.58±1.38, 2.46±1.59, 2.51± 1.31, 2.63±1.03, 2.80±1.31. Conclusions: The purpose of cochlear implantation is verbal/auditory perception and it can be achieved better, when cochlear implantations is performed in younger ages. The earlier a child with hearing loss is implanted, the better the likely outcome.
