- Quality of life evaluation in children with cochlear implants(2015) ALMEIDA, Renata Paula de; MATAS, Carla Gentile; COUTO, Maria Inês Vieira; CARVALHO, Ana Claudia Martinho dePURPOSE: To evaluate the quality of life of children with cochlear implants from the perspective of their parents. METHODS: A clinical and cross-sectional study was conducted with 15 parents of children using cochlear implants of both genders aged between 2 and 12 years old. Parents of these children answered the questionnaire ""Children with Cochlear Implants: Parental Perspective"" (CCIPP). Data related to auditory category and time of cochlear implants use were collected from medical records of the children. The percentages of responses on the CCIPP domains were tabulated and descriptively and inferentially analyzed. RESULTS: The cochlear implants had a positive effect on the quality of life of children in the self-reliance (58.9%) and social relationships (56.7%) domains. No correlation was observed between the time of cochlear implants activation (months) and any of the CCIPP domains. However, children with 24 months or less of cochlear implant use presented higher percentages on the communication domain than those with more than 24 months of cochlear implants use. A negative correlation was observed between the auditory category and the effects of the implant domain. CONCLUSION: From the perspective of parents, the use of cochlear implants improves the quality of life of their children; the shorter the time of cochlear implants use, the higher the improvement in quality of life; and the more developed the auditory skills, the lower the percentage of quality of life improvement with the cochlear implants.
- Sequential bilateral cochlear implant: results in children and adolescents(2019) ALMEIDA, Gabriela Felix Lazarini; MARTINS, Marcella Ferrari; COSTA, Lucas Bevilacqua Alves da; COSTA, Orozimbo Alves da; CARVALHO, Ana Claudia Martinho deIntroduction: The use of the bilateral cochlear implants can promote the symmetrical development of the central auditory pathways, thus benefiting the development of auditory abilities and improving sound localization and the ability of auditory speech perception in situations of competitive noise. Objective: To evaluate the ability of speech perception in children and adolescents using sequential bilateral cochlear implants, considering the association of these variables: age at surgery, time of device use and interval between surgeries. Methods: A total of 14 individuals between 10 and 16 years of age, who demonstrated surgical indication for the use of sequential bilateral cochlear implants as intervention in the auditory habilitation process, were assessed. The speech perception ability was assessed through sentence lists constructed in the Portuguese language, presented in two situations: in silence, with fixed intensity of 60 dB SPL, and in competitive noise, with a signal-to-noise ratio of +15 dB. The evaluation was performed under the following conditions: unilateral with the first activated cochlear implant, unilateral with the second activated cochlear implant and bilateral with both devices activated. Results: The results of the speech perception tests showed better performance in both silence and in noise for the bilateral cochlear implant condition when compared to the 1st cochlear implant and the 2nd cochlear implant alone. A worse result of speech perception was found using the 2nd cochlear implant atone. No statistically significant correlation was found between age at the surgical procedure, interval between surgeries and the time of use of the 2nd cochlear implant, and the auditory speech perception performance for all assessed conditions. The use of a hearing aid prior to the 2nd cochlear implant resulted in benefits for auditory speech perception with the 2nd cochlear implant, both in silence and in noise. Conclusion: The bilateral cochlear implant provided better speech perception in silence and in noise situations when compared to the unilateral cochlear implant, regardless of the interval between surgeries, age at the surgical procedure and the time of use of the 2nd cochlear implant. Speech perception with the 1st cochlear implant was significantly better than with the 2nd cochlear implant, both in silence and in noise. The use of the hearing aid prior to the 2nd cochlear implant influenced speech perception performance with the 2nd cochlear implant, both in silence and in noise.

- Fatores que influenciam na participação dos pais de crianças usuárias de implante coclear na (re)habilitação oral: revisão sistemática(2013) COUTO, Maria Inês Vieira; CARVALHO, Ana Claudia MartinhoPURPOSE: To identify and analyze factors that influence the participation of parents in the rehabilitation process of children with cochlear implants (CI). RESEARCH STRATEGY: Question formulation and articles selection in three databases using the following keywords: cochlear implant (implante coclear) and parents (pais). SELECTION CRITERIA: Complete original articles published in Brazilian Portuguese or English, with direct participation of parents of children with CI. DATA ANALYSIS: Articles were fully read. Data regarding characterization of the centers, research methodology and content were analyzed. RESULTS: Thirteen articles were selected based on the established criteria. The types of studies were cross-sectional and case-control (interview technique). The following influential factors were identified: pre-CI surgery factors (knowledge about CI, quality and quantity of information, specialist's advices, ethical and biomedical aspects, rehabilitation engagement, contact with experienced families, social service support and overall costs); rehabilitation aspects (CI use, oral communication modality, regular school, other disabilities, social and demographic aspects and rehabilitation program's effectiveness); other important influential processes (communication modality, auditory and language development, second oral language learning, as well as parent's behavior and satisfaction). CONCLUSION: The engagement of parents in the rehabilitation process of children with CI depends on several distinct influential factors which audiologists should understand and consider when elaborating a rehabilitation program.
- Maturação dos potenciais evocados auditivos de longa latência em crianças ouvintes: revisão sistemática(2017) SILVA, Liliane Aparecida Fagundes; MAGLIARO, Fernanda Cristina Leite; CARVALHO, Ana Claudia Martinho de; MATAS, Carla GentileABSTRACT Purpose To analyze how Auditory Long Latency Evoked Potentials (LLAEP) change according to age in children population through a systematic literature review. Research strategies After formulation of the research question, a bibliographic survey was done in five data bases with the following descriptors: Electrophysiology (Eletrofisiologia), Auditory Evoked Potentials (Potenciais Evocados Auditivos), Child (Criança), Neuronal Plasticity (Plasticidade Neuronal) and Audiology (Audiologia). Selection criteria Level 1 evidence articles, published between 1995 and 2015 in Brazilian Portuguese or English language. Data analysis Aspects related to emergence, morphology and latency of P1, N1, P2 and N2 components were analyzed. Results A total of 388 studies were found; however, only 21 studies contemplated the established criteria. P1 component is characterized as the most frequent component in young children, being observed around 100-150 ms, which tends to decrease as chronological age increases. The N2 component was shown to be the second most commonly observed component in children, being observed around 200-250 ms.. The other N1 and P2 components are less frequent and begin to be seen and recorded throughout the maturational process. Conclusion The maturation of LLAEP occurs gradually, and the emergence of P1, N1, P2 and N2 components as well as their latency values are variable in childhood. P1 and N2 components are the most observed and described in pediatric population. The diversity of protocols makes the comparison between studies difficult.
- Auditory and communicative abilities in the auditory neuropathy spectrum disorder and mutation in the Otoferlin gene: clinical cases study(2012) COSTA, Nayara Thais de Oliveira; MARTINHO-CARVALHO, Ana Claudia; CUNHA, Maria Claudia; LEWIS, Doris RuthiThis study had the aim to investigate the auditory and communicative abilities of children diagnosed with Auditory Neuropathy Spectrum Disorder due to mutation in the Otoferlin gene. It is a descriptive and qualitative study in which two siblings with this diagnosis were assessed. The procedures conducted were: speech perception tests for children with profound hearing loss, and assessment of communication abilities using the Behavioral Observation Protocol. Because they were siblings, the subjects in the study shared family and communicative context. However, they developed different communication abilities, especially regarding the use of oral language. The study showed that the Auditory Neuropathy Spectrum Disorder is a heterogeneous condition in all its aspects, and it is not possible to make generalizations or assume that cases with similar clinical features will develop similar auditory and communicative abilities, even when they are siblings. It is concluded that the acquisition of communicative abilities involves subjective factors, which should be investigated based on the uniqueness of each case.
- Maturação dos potenciais evocados auditivos de longa latência em crianças ouvintes: análise do complexo P1-N1-P2-N2(2017) SILVA, Liliane Aparecida Fagundes; MAGLIARO, Fernanda Cristina Leite; CARVALHO, Ana Claudia Martinho de; MATAS, Carla GentileABSTRACT Purpose The purpose of this study was to monitor the emergence and changes to the components of the Long Latency Auditory Evoked Potentials (LLAEP) in normal hearing children. Methods This longitudinal study included children of both genders: seven aged between 10 and 35 months, and eight children between 37 and 63 months. The electrophysiological hearing evaluation consisted of analysis of LLAEP obtained in a sound field generated with loudspeakers positioned at an azimuth of 90°, through which the syllable /ba/ was played at an intensity of 70 dB HL. Each child underwent an initial evaluation followed by two re-evaluations three and nine months later. Results The emergence of LLAEP components across the nine-month follow-up period was observed. P1 and N2 were the most common components in children of this age range. There was no statistically significant difference regarding the occurrence of P1, N1, P2, and N2 components amongst younger and older children. Regarding latency values, the greatest changes overtime were observed in the P1 component for younger children and in the N2 component for older children. Only the P1 component significantly differed between the groups, with the highest latency values observed in younger children. Conclusion LLAEP maturation occurs gradually and the emergence of complex components appears to be related more to the maturation of the central auditory nervous system than to chronological age.
- Aquisição de vocábulos em crianças usuárias de implante coclear(2014) SOUSA, Aline Faria; COUTO, Maria Inês Vieira; CARVALHO, Ana Claudia Martinho de; MATAS, Carla Gentile; BEFI-LOPES, Débora MariaPURPOSE: to analyze word acquisition in early oral language development of a group of children with cochlear implants. METHODS: this consisted on a clinical, prospective and longitudinal study. Five mothers of children with cochlear implants participated. The mothers reported the words that were spontaneously produced by their children. The Language Development Survey adapted to Brazilian Portuguese was administered once a month, totaling six moments per child. The paired t-test was used on the longitudinal data analysis. RESULTS: the mean number of words spontaneously produced by the group of children gradually increased from the first to the sixth month: 38 to 58.8 words. There were significant differences in the number of words produced on Moment 1 and Moment 5 (p = 0.016) and between Moment 1 and Moment 6 (p = 0.010). The categories with the greatest number of words produced by children were other, people, modifiers and actions. The categories with the greatest increase were modifiers, body parts and other. CONCLUSIONS: the group of children with cochlear implants showed a gradual increase in the number of words spontaneously (mainly other, modifiers, people and actions) produced over a period of six months, being significant after the fifth month of Speech-Language therapy. The number of words produced increased with higher significance with longer intervention periods. It is suggested that Speech-Language Pathologists apply the formulary on a six-month interval as this is an ideal period to evidence lexical acquisition.
