“…De acordo com alguns pesquisadores, crianças implantadas antes dos dois anos, podem apresentar alteração no desenvolvimento da linguagem, todavia, com o passar do tempo de uso do IC, é possível que a criança alcance o desenvolvimento da linguagem de uma criança ouvinte de mesma idade cronológica 22,23 . Crianças surdas com IC e sem IC foram avaliadas longitudinalmente.…”

, Maria da Piedade Resende da Costa(3) RESUMOObjetivo: analisar e comparar a expressão verbal de crianças ouvintes e crianças usuárias de implante coclear. Métodos: os participantes foram 12 crianças ouvintes, entre 4 anos e 2 mês e 4 anos e 11 meses, e 10 crianças portadoras de perda auditiva neurossensorial profunda, usuárias de implante coclear, de 4 anos e 3 meses a 5 anos e 0 meses. Conflito de interesses: inexistente palavras são combinadas para formar as frases. O componente "Conteúdo" refere-se ao sentido transmitido pelas palavras em frases, sentenças ou no discurso. Já o componente "Uso", inclui o propósito do falante direcionado para os outros (informar, solicitar, questionar) ou para si mesmo (raciocinar, auto-lembrar) 1 . É a interação entre forma, conteúdo e uso que constituem a linguagem normal. A linguagem pode ser expressa de várias formas, ou seja, é possível recorrer ou fazer uso de diferentes sistemas simbólicos, como desenhos, gestos, pintura. Todavia, a forma de utilização de linguagem mais peculiar é a falada ou oral, pois a mesma constitui uma forma de comunicação que capacita os seres humanos a transmitir informações com especificidade e detalhes 2 .A linguagem oral envolve dois processos importantes: a Compreensão Verbal e a Expressão Verbal. A Compreensão Verbal precede a Expressão e, para que a mesma ocorra, é imprescindível que se tenha audição para fala. Verifica-se que qualquer prejuízo na audição interfere na compreensão verbal, bem como na formação e inter-relação de INTRODUÇÃOA linguagem é a capacidade de abstrair e simbolizar os signos linguísticos de forma significativa e contextualizada. Ela é essencial para a interação dos homens entre si e imprescindível para que o processo de comunicação se estabeleça. Pode-se dizer que a linguagem é constituída de três componentes (Forma, Conteúdo e Uso). O componente "Forma" abrange os aspectos que conferem estrutura à língua. Diz respeito ao modo como os sons são combinados para formar as palavras e as

“…For many of these patients, a CI provides sufficient auditory input to support the development of spoken-language skills as the primary modality of communication (Niparko et al 2010;Yoshinaga-Itano et al 2010). However, some children do not achieve this goal (Davidson et al 2011) and large individual differences in speech perception and language outcomes of implanted children are widely reported (e.g., Geers 2004;Manrique et al 2004;Niparko et al 2010). Where an individual patient falls on this outcome spectrum is often not apparent until 2-3 years after CI surgery, when precise clinical measures of spoken-language abilities have been obtained over time (Robbins et al 2004;Ganek et al 2012).…”

Acoustic Temporal Modulation Detection in Normal-Hearing and Cochlear Implanted Listeners: Effects of Hearing Mechanism and Development

Temporal modulation detection ability matures over many years after birth and may be particularly sensitive to experience during this period. Profound hearing loss during early childhood might result in greater perceptual deficits than a similar loss beginning in adulthood. We tested this idea by measuring performance in temporal modulation detection in profoundly deaf children and adults fitted with cochlear implants (CIs). At least two independent variables could constrain temporal modulation detection performance in children with CIs: altered encoding of modulation information due to the CIauditory nerve interface, and atypical development of central processing of sound information provided by CIs. The effect of altered encoding was investigated by testing subjects with one of two different hearing mechanisms (normal hearing vs. CI) and the effect of atypical development was studied by testing two different age groups. All subjects were tested for their ability to detect acoustic temporal modulations of sound amplitude. A comparison of the slope, or cutoff frequency, of the temporal modulation transfer functions (TMTFs) among the four subject groups revealed that temporal resolution was mainly constrained by hearing mechanism: normal-hearing listeners could detect smaller amplitude modulations at high modulation frequencies than CI users. In contrast, a comparison of the height of the TMTFs revealed a significant interaction between hearing mechanism and age group on overall sensitivity to temporal modulation: sensitivity was significantly poorer in children with CIs, relative to the other three groups. Results suggest that there is an agespecific vulnerability of intensity discrimination or non-sensory factors, which subsequently affects sensitivity to temporal modulation in prelingually deaf children who use CIs.

“…The sooner an appropriate sound-processor map can be fit, the more likely an optimized outcome will be achieved for the child (e.g., Manrique, Cervera-Paz, Huarte, & Molina, 2004). However, generating an appropriate map is a process that occurs over numerous visits, primarily because young children cannot engage in these kinds of tasks long enough to obtain reliable behavioral responses on all electrodes.…”

Purpose: This study evaluated the use of telepractice for measuring cochlear implant (CI) behavioral threshold ( T) levels in children using conditioned play audiometry (CPA). The goals were to determine whether (a) T levels measured via telepractice were not significantly different from those obtained in person, (b) response probability differed between remote and in-person conditions, and (c) the remote visit required more time than the in-person condition. Method: An ABBA design (A, in-person; B, remote) was split across 2 visits. Nineteen children aged 2.6-7.1 years participated. T levels were measured using CPA for 3 electrodes per session. A "hit" rate was calculated to determine whether the likelihood of obtaining responses differed between conditions. Test time was compred across conditions. A questionnaire was administered to assess parent /caregiver attitudes about telepractice. Results: Results indicated no significant difference in T levels between conditions. Hit rates were not significantly different between in-person and remote conditions (98% vs. 97%, respectively). Test time was similar between conditions. Questionnaire results revealed that 100% of caregivers would use telepractice for CI appointments either some or all of the time. Conclusion: Telepractice is a viable option for routine pediatric programming appointments for children using CPA to set behavioral thresholds.
