RESUMO
Objective To investigate the development of auditory and speech skills and the safety and stability among the prelingually deaf children with Nurotron Venus cochlear implants.Methods A total of 78 cochlear implant subjects were recruited from the first of affiliated hospital of Zhengzhou university.They were divided into 5 groups according to the ages at the time of implantation: group A(between 13 and 24 months), group B(between 25 and 36 months),group C(between 37 and 48 months),group D(between 49 and 72 months),group E(between 73 and 96 months).Children were evaluated by IT-MAIS(group A and B) and MAIS(group C,D and E) before the surgery and 1 month,3 months,6 months, and 12 months after surgery.All children were evaluated by MUSS questionnaires 1 months, 3 months,6 months,and 12 months after surgery.Post-operative cochlear radiographs determine the position of the CIs.The complications and usage of The CIs were followed up.Results The auditory and speech ability of children with CIs improved constantly.The auditory and speech of different groups were statistically significant.All the surgeries of 78 cases Nurotron-Venus cochlear implants were successful.Post-operative cochlear radiographs showed electrodes in the normal position.2 cases had processor failures.The remaining CIs were implanted completely.Conclusion Within 1 year, the ability of auditory and speech improved gradually.The scores of auditory and speech about the small age groups are lower than older children in the early days.There is no influence on the audition in 12 months.Small children's scores of speech are lower than older children in 12 months.The better ability to integrate auditory information is , the better the ability to speak is.The Nurotron CIs work safety and effectively.
RESUMO
Existe uma grande dificuldade para determinar precocemente crianças que se beneficiariam ou não com o implante coclear, até porque devido à pouca idade são muito sutis as respostas apresentadas. OBJETIVO: Comparar os resultados obtidos através da vídeo-gravação de situações de interação de crianças candidatas ao implante coclear com os resultados obtidos através de protocolos de avaliação. MÉTODO: Fizeram parte da amostra 7 crianças com idade média de 39,7 meses, portadores de perda auditiva neurossensorial profunda. Foram aplicados os questionários IT-MAIS e MUSS aos pais e os resultados foram comparados com a observação da vídeo-gravação destas crianças. RESULTADOS: Foi possível observar que os dados são compatíveis no que se refere às etapas auditivas. No entanto, no que se refere ao questionário MUSS, os dados obtidos na observação lúdica são bastante diferentes. O questionário leva em consideração apenas a uso da linguagem oral e, portanto, a maioria das crianças apresentou um escore muito baixo. CONCLUSÃO: A observação lúdica permitiu traçar um perfil mais amplo do comportamento lingüístico e de aspectos relativos à linguagem apresentando diferenças do questionário.
There is a great difficulty in determining earlier on which children would benefit or not from cochlear implants, especially because of their young age, the responses they give are very subtle. AIM: To compare results obtained through video-recording of the interactions of children who may receive a cochlear implant with the results obtained through evaluation protocols. METHOD: Seven children, with an average age of 39.7 months, with profound hearing loss were selected for the study. IT-MAIS and MUSS questionnaires were given to their parents/guardians of these children and the results were compared with the observation of the video-recordings. RESULTS: It was possible to observe that the data is compatible with the auditory stages. However, the MUSS questionnaire data gathered during playful activities is very different . The questionnaire only takes into consideration the use of verbal language and therefore the majority of the evaluated children inevitably score low. CONCLUSION: Observing children play allows us to trace a better profile of linguistic behavior and aspects relative to language, that may presented differences in the questionnaire.
