ABSTRACT Purpose This study aimed to evaluate the contribution of assistive listening technology with wireless connectivity in cochlear implant (CI) users in reverberating and noise situations. Methods Prospective cross-sectional study approved by the Institutional Ethics Committee (CAAE 8 3031418.4.0000.0068). Adolescents and adults CI users with pre- or post-lingual deafness were selected. For bilateral users, each ear was assessed separately. Speech recognition was assessed using recorded lists of disyllabic words presented at 65 dBA at 0° azimuth with and without the Wireless Mini Microphone 2 (Cochlear™) connected to the Nucleus®6 speech processor. Room reverberation was measured as 550 ms. To assess the contribution of the assistive listening device (ALD) in a reverberating environment, speech recognition was assessed in quiet. To assess the contribution of the ALD in reverberation and noise, speech recognition was presented at 0° azimuth along with the noise coming from 8 loudspeakers symmetrically arranged 2 meters away from the center with multi-talker babble noise using signal to noise ratio of +10dB. To avoid learning bias or fatigue, the order of the tests was randomized. Comparison of means was analyzed by t test for paired samples, adopting significance level of p <0.005. Results Seventeen patients with a mean age of 40 years were invited and agreed to participate, with 2 bilateral participants, totaling 19 ears assessed. There was a significant positive contribution from the Mini Mic2 in reverberation, and noise+reverberation (p <0.001). Conclusion ALD was able to improve speech recognition of CI users in both reverberation and noisy situations.

Abstract Introduction Facial nerve stimulation (FNS) is a complication in cochlear implant (CI) when the electrical current escapes from the cochlea to the nearby facial nerve. Different management to reduce its effects are available, although changes might result in a less-than-ideal fitting for the CI user, eventually reducing speech perception. Objective To verify the etiologies that cause FNS, to identify strategies in managing FNS, and to evaluate speech recognition in patients who present FNS. Methods Retrospective study approved by the Ethical Board of the Institution. From the files of a CI group, patients who were identified with FNS either during surgery or at any time postoperatively were selected. Data collection included: CI manufacturer, electrode array type, age at implantation, etiology of hearing loss, FNS identification date, number of electrodes that generated FNS, FNS management actions, and speech recognition in quiet and in noise. Results Data were collected from 7 children and 25 adults. Etiologies that cause FNS were cochlear malformation, head trauma, meningitis, and otosclerosis; the main actions included decrease in the stimulation levels followed by the deactivation of electrodes. Average speech recognition in quiet before FNS was 86% and 80% after in patients who were able to accomplish the test. However, there was great variability, ranging from 0% in quiet to 90% of speech recognition in noise. Conclusion Etiologies that cause FNS are related to cochlear morphology alterations. Facial nerve stimulation can be solved using speech processor programming parameters; however, it is not possible to predict outcomes, since results depend on other variables.

Abstract Introduction Recently, there have been significant advancements in transcanal endoscopic ear surgery (TEES). The combination of rigid and thin otoendoscopes with highdefinition cameras enabled a less invasive transcanal access to the middle ear and a clearer view of the surgical field. Several surgeons have recently published studies about cholesteatoma resection via transcanal endoscopic surgery, even in cases where the disease has extended to the mastoid, requiring transcanal endoscopic mastoidectomy. Objectives To analyze the currently available literature on transcanal endoscopic inside-out mastoidectomy, and to determine its efficacy as a surgical technique by evaluating the disease’s relapse/recurrence rate. Data Synthesis Initially, the titles and abstracts of articles identified were analyzed. At this stage, 117 articles were analyzed, 97 of which were excluded for not meeting the inclusion criteria. The 20 remaining articles were further evaluated. The articles were classified on the basis of five levels of scientific evidence. Final Comments The analysis of the studies showed that the transcanal endoscopic approach is effective in providing access to the attic or antrum, especially in cases of sclerotic mastoids. There was only one study with grade A recommendation, which showed the efficacy of endoscopic ear surgery in the treatment of cholesteatoma. Furthermore, there were three studies with grade B recommendation, showing less relapse/recurrence after TEES. More studies with grade A and B recommendations are needed to better evaluate the effectiveness of TEES, especially compared with that of traditional microscopic surgery. Recently TEES .

RESUMO Objetivo O objetivo deste estudo foi avaliar o efeito do sistema CROS em fenômenos como efeito sombra da cabeça em usuários de implante coclear unilateral. Método Estudo transversal prospectivo, aprovado pelo conselho de ética sob protocolo 2.128.869. Onze adultos com surdez de instalação pós-lingual usuários de IC Advanced Bionics unilateral foram selecionados. O reconhecimento de fala foi avaliado com palavras gravadas apresentadas a 65dBA a 0o azimute e a (90o no lado contralateral ao IC), com ruído a 55dBA, usando somente o IC e IC+sistema CROS. Os resultados foram analisados usando teste t pareado com alfa de 0,05. Resultados Os escores médios de reconhecimento de fala foram significativamente melhores com IC + CROS em relação à condição apenas IC (p <0,05, p <0,005 e p <0,005 respectivamente). Na apresentação à frente não foram encontradas diferenças significantes. Conclusão Os usuários de IC unilateral sem resíduo útil para uso de prótese auditiva ou impossibilitados de submeter-se à cirurgia bilateral podem se beneficiar do dispositivo CROS para o reconhecimento de fala, sobretudo quando a fala for apresentada ao lado contralateral ao IC.

ABSTRACT Purpose The aim of this study was to evaluate the contribution of the CROS system on the head shadow effect in unilateral implant users. Methods Prospective cross-sectional study, approved by the ethics committee under protocol 2.128.869. Eleven adults with post-lingual deafness users of unilateral Advanced Bionics CI were selected. Speech recognition was evaluated with recorded words presented at 65dBA at 0o azimuth and at 90o on the side contralateral to the CI, with noise at 55dBA, using CI alone and CI + CROS system. The results were analyzed using paired t-test with a 0.05 alpha. Results The mean speech recognition scores were significantly better with CI + CROS in relation to the condition of CI alone (p <0.05, p <0.005 and p <0.005 respectively). In the presentation at 0o azimuth, no significant differences were found. Conclusion Users of unilateral CI without useful residual hearing for the use of hearing aids or unable to undergo bilateral surgery can benefit from the CROS device for speech recognition, especially when the speech is presented on the side contralateral to the CI.

RESUMO Objetivo identificar se as diferenças no desenvolvimento da aquisição das habilidades auditivas iniciais em crianças após o implante coclear, unilateral ou bilateral, podem ser evidenciadas durante o primeiro ano de uso. Métodos estudo longitudinal retrospectivo de levantamento de prontuários. Foram incluídas crianças que receberam o implante coclear antes dos 4 anos de idade, separadas em dois grupos. O primeiro, composto por crianças implantadas unilateralmente e o segundo, por crianças implantadas bilateral e simultaneamente. Foram coletados os dados referentes à escala IT-MAIS (Infant-Toddler Meaningful Auditory Integration Scale) antes da cirurgia e três meses, seis meses e um ano após a cirurgia. Esses resultados foram comparados com os marcadores clínicos já existentes. Além disso, as famílias foram classificadas segundo a Escala de Avaliação de Envolvimento Familiar. Resultados foram avaliados os resultados de 29 crianças com implante coclear bilateral e 30 crianças com implante coclear unilateral. A pontuação obtida no IT-MAIS dos dois grupos foi semelhante aos marcadores clínicos. Quanto à Escala de Avaliação de Envolvimento Familiar, houve diferença, mostrando que as famílias do grupo dos bilaterais estavam mais envolvidas. Conclusão no primeiro ano de uso do implante coclear, o desenvolvimento da aquisição das habilidades auditivas iniciais das crianças implantadas bilateralmente não diferiu do desenvolvimento de crianças implantadas unilateralmente, sugerindo que as habilidades auditivas iniciais são passíveis de desenvolvimento com entrada auditiva unilateral.

ABSTRACT Purpose To identify the development of initial auditory skills in children with unilateral and bilateral cochlear implant during the first year of use. Methods Retrospective longitudinal study of medical records of children who received cochlear implant under the age of four, separated into two groups. The first, composed of children implanted unilaterally and the second, by children implanted and simultaneously. Data on the IT-MAIS scale (Infant-Toddler Meaningful Auditory Integration Scale) were collected before surgery and three months, six months and one year after surgery. These results were compared with the existing Clinical Markers. In addition, the family’s classification was noted, according to the Family Involvement Assessment Scale. Results The data of 29 children with bilateral cochlear implant and 30 children with unilateral cochlear implant were evaluated. The IT-MAIS score of the two groups was similar to the Clinical Markers. Regarding the Family Involvement Assessment Scale, there was a difference, showing that families in the bilateral group were more involved. Conclusion In the first year of use of the cochlear implant, the development of children implanted bilaterally did not differ from the development of children implanted unilaterally, suggesting that initial auditory skills are likely to develop with unilateral auditory input.

Abstract Introduction The use of cochlear implants and hearing aids (bimodal) has been growing with the expansion of the indication for them, and it is important to ensure protocols so that there is a balance of the loudness regarding the two devices. Objective To evaluate if the limited complex sounds present in the frequency bands of the current devices enable the balance of the loudness in adult users of bimodal stimulation, and to analyze if speech recognition improves after balancing. Methods A prospective cross-sectional study with convenience sampling. The sample was composed of 25 adults who had used either a cochlear implant for at least 6 months or a contralateral hearing aid, with a mean age of 46 years. The balancing of the loudness was performed in an acoustic room with the computer's sound box (0° azimuth at 70 dB SPL). The instrumental sounds were filtered through eight different frequency bands. The patients used both hearing devices and were asked if the sound was perceived to be louder in one of the ears or centrally. The speech test was evaluated with sentence silence (65 dB SPL) and/or noise signal ratio of 0 dB/+ 10 dB in free field at 0° azimuth, before and after balancing. Results: Out of the 25 patients, 5 failed to achieve balance at every tested frequency, and 3 achieved balance at almost every frequency, except 8 kHz. There was a significant difference between the speech recognition test only in silence before and after balancing. Conclusion: Most patients achieved sound equalization at all evaluated frequencies under the complex-sound protocol. Additionally, most patients experienced improved speech recognition after balancing.

RESUMO Objetivo avaliar a teleconsulta de forma síncrona no mapeamento do implante coclear (IC) como ferramenta de educação continuada para fonoaudiólogos em capacitação e treinamento. Métodos estudo prospectivo longitudinal, na modalidade de preceptorado clínico, com teleconsulta de forma síncrona direcionada ao atendimento de mapeamento dos usuários de IC. A educação continuada foi oferecida aos fonoaudiólogos aprimorandos em um hospital e o fonoaudiólogo tutor, em unidade remota. A plataforma utilizada permitiu ao tutor visualizar e realizar intervenções na tela de mapeamento do IC. Foram aplicados três questionários abrangendo os marcadores de ensino; qualidade e importância da teleconsulta; interação entre os profissionais e autoavaliação sobre a confiança na realização das etapas do mapeamento antes e após as teleconsultas. Resultados participaram sete fonoaudiólogos e foram analisados 268 atendimentos, ao longo de três anos. Os marcadores clínicos mostraram, na média e individualmente, que houve correlação estatística com diminuição do número de intervenções totais, nas intervenções do mapeamento do IC e raciocínio clínico, no decorrer das sessões. A média das notas nas avaliações da importância da teleconsulta foi 9,7 e a interação com o tutor, 9,3. Na autoavaliação, todos os aprimorandos responderam que estavam “nada/pouco confiantes” para as etapas do mapeamento antes da intervenção e, ao final do curso, responderam “moderadamente/muito confiantes” para as mesmas etapas. Conclusão o uso da teleconsulta síncrona foi viável e eficiente como ferramenta de ensino para fonoaudiólogos. Foi possível observar a diminuição do número de intervenções ao longo do tempo, evidenciando a curva de aprendizado.

ABSTRACT Purpose To evaluate the teleconsultation synchronously in the mapping of the cochlear implant (CI) as an ongoing professional development tool in training programmes for audiologists. Methods It was a prospective longitudinal study, in the form of clinical preceptor with teleconsultation in a synchronous way directed at assisting the mapping of CI users. Distance learning was offered to fellow audiologists in a hospital and the audiology tutor in the remote unit. The chosen platform allowed the tutor to view and perform interventions on the CI mapping screen. Three questionnaires covering teaching markers were applied; the quality and importance of teleconsultation; interaction between professionals; and self-assessment of confidence in carrying out the mapping steps before and after teleconsultations. Results Seven audiologists participated; 268 consultations were analyzed over three years. The clinical markers showed, on average and individually, that there is a statistical correlation with a decrease in the number of total interventions, in the interventions of CI mapping and clinical reasoning throughout the sessions. The average of the scores of the importance of teleconsultation was 9.7 and the interaction with the tutor was 9.3. In the self-assessment, all audiologists responded that they were “not at all/not very confident” for the mapping steps before the intervention, and at the end of the course they responded “moderately/very confident” for the same steps. Conclusion The use of synchronous teleconsultation was feasible and efficient as a teaching tool for audiologists. It was possible to observe the decrease in the number of interventions over time, evidencing the learning curve.

RESUMO Objetivo identificar a contribuição do microfone omnidirecional (T-Mic) e microfone direcional adaptativo (UltraZoom) do processador de som Naída CIQ70 para o reconhecimento da fala no ruído e em ambiente reverberante. Identificar a contribuição do processador de som Naída CIQ70 para usuários do processador Harmony. Métodos participaram do estudo sete adultos com implante coclear unilateral, usuários do processador de som Harmony. O reconhecimento de sentenças foi avaliado em silêncio, em sala reverberante (RT60 de 553 ms) e ruído de 42,7 dBA (Leq), com os processadores Harmony e Naída CIQ70. A contribuição do microfone direcional UltraZoom foi avaliada no ruído. As sentenças gravadas foram apresentadas a 0° azimute. O ruído (babble noise) foi apresentado a + 5 dB SNR, a 90° azimute. Os participantes avaliaram subjetivamente a clareza do som e a dificuldade de escutar nas várias condições do teste. Resultados a média do reconhecimento de sentenças no silêncio com reverberação foi de 38,5% com o Harmony e 66,5% com o Naída CIQ70. A pontuação média de reconhecimento de sentenças no ruído foi de 40,5% com o Naída CIQ70, sem UltraZoom, e de 64,5% com UltraZoom. Nas classificações subjetivas de clareza do som e facilidade de escuta no ruído, nenhuma diferença foi identificada entre as condições de teste. Conclusão para usuários experientes do processador de som Harmony, a compreensão da fala em silêncio em uma sala reverbente foi significativamente melhor com o Naída CIQ70. O uso de uma tecnologia de microfone direcional adaptativa (UltraZoom) contribuiu para o reconhecimento de fala no ruído.

Abstract Purpose 1) To measure speech understanding in noise with the Naída Q70 in the omnidirectional microphone mode (T-Mic) and adaptive directional microphone mode (UltraZoom) in reverberating acoustics and noisy conditions. 2) To measure improvement in speech understanding with use of the Advanced Bionics (AB) Naída Q70 sound processor for existing Harmony users. Methods Seven adult unilateral cochlear implant (CI) recipients, who were experienced users of the Harmony sound processor, participated in the study. Sentence recognition was evaluated in quiet in a reverberating room, with Harmony and Naída CI Q70 processors. Effectiveness of Naída CI Q70’s UltraZoom directional microphone was evaluated in noise. Target stimuli were recorded Portuguese sentences presented from 0° azimuth. Twenty-talker babble was presented at +5dB SNR from ±90° azimuth. In addition to sentence recognition, the participants also rated the clarity of sound and difficulty of listening in the various test conditions. In order to evaluate the outcomes under more realistic acoustic conditions, tests were conducted in a non-sound treated reverberant room (RT60 of 553 ms and noise floor of 42.7 dBA (Leq). Results The average sentence recognition in quiet in the reverberant non-sound treated room was 38.5% with the Harmony and 66.5% with Naída CI Q70. The average sentence recognition score in noise was 40.5% with Naída CI Q70 without UltraZoom and 64.5% with UltraZoom. For subjective ratings of sound clarity and listening ease in noise no difference were identified between the test conditions. Conclusion For experienced users of the Harmony sound processor, speech understanding in quiet in a reverberating room was significantly improved with the Naída CI Q70. The use of an adaptive directional microphone technology (UltraZoom) enhanced speech perception in noise.

OBJECTIVES: Currently, cochlear implant procedures are becoming increasingly broad and have greatly expanded. Bilateral cochlear implants and cochlear implants are more frequently applied in children. Our hypothesis is that the video head impulse test may be more sensitive than the caloric test in detecting abnormal vestibular function before cochlear implant surgery. The objective of this study was to compare the video head impulse test and caloric test results of patients selected for cochlear implant procedures before surgery. METHODS: The patients selected for cochlear implant surgery were submitted to a bithermal caloric test and video head impulse test. RESULTS: By comparing angular slow phase velocity values below 5° in the bithermal caloric test (hypofunction) and video head impulse test with a gain lower than 0.8, we identified 37 (64.9%) patients with vestibular hypofunction or canal paresis and 21 (36.8%) patients with abnormal video head impulse test gain before the cochlear implant procedure. Of the 37 patients with caloric test vestibular hypofunction, 20 (54%) patients exhibited an abnormal gain in the video head impulse test. CONCLUSION: The caloric test is more sensitive than the video head impulse test (Fisher’s exact test, p=0.0002) in detecting the impaired ear before cochlear implant delivery. The proportion of caloric test/video head impulse test positive identification of abnormal vestibular function or caloric test/video head impulse test sensitivity was 1.8:1.

Abstract Introduction The cochlear implants centers in the world are studying the cochlear implantation in children with multiple handicaps. Objective To develop a questionnaire to analyze the subjective benefits of the cochlear implantation in multiple handicapped children according to their parent's perspective. Methods A questionnaire was applied to 14 families of multiple handicapped children, aging from 2–12 years old and having from 11 months to 11 years of implant use. Results The social-emotional abilities were improved because of many factors, such as: auditory exposure, which happened in 84% of the children; recognition of their own names, which increased in 56%; and development of eye contact, in 28% of the subjects. Other benefits appeared to be: music appreciation and more attention and adherence to other therapies and school activities. Besides, some children became interested in objects, playing with other children, and more adapted to daily routines. Thirty-five percent of the children acquired oral language, mainly the bilaterally implanted, while 14% of them were engaged in sign language. Although all of the children showed a significant improvement in communication, the emotional issues of some families and the severity of the handicaps negatively impacted the outcomes. In spite of the families' acknowledgement of some benefits, the diagnosis of autism spectrum disorder caused frustration, requiring a readjustment of the expectations. Conclusion The questionnaire turned out to be an adequate tool to reveal the social-emotional benefits of cochlear implantation. Although oral language was not the major outcome in these cases, the cochlear implant benefits involved the whole family. All of the families recommended the implant to other children in a similar situation.

Resumo Introdução: Os implantes cocleares (IC) são indiscutivelmente um método eficaz de recuperação da função auditiva de pacientes surdos. Objetivo: Descrever o protocolo de avaliação vestibular pré-operatória em sujeitos que serão submetidos ao IC. Método: Nosso protocolo institucional prevê o diagnóstico vestibular por meio de seis testes simples: testes de Romberg e Fukuda, nistagmo espontâneo, Head Impulse Test, Head Shaking Nistagmus, prova calórica. Resultados: Foram avaliados 21 pacientes com média de 42,75 ± 14,38 anos. Apenas 28% da amostra apresentaram todos os testes normais. A presença de informação vestibular assimétrica foi documentada pela prova calórica em 32% da amostra e o nistagmo espontâneo mostrou-se pista importante para seu diagnóstico. A arreflexia vestibular bilateral foi diagnosticada em quatro sujeitos; arreflexia unilateral em três e hiporreflexia bilateral em dois. O Head Impulse Test mostrou-se indicador significante (p = 0,0001) para diagnosticar arreflexia da orelha testada. O teste de Romberg sensibilizado em almofada foi capaz de diagnosticar os comprometimentos severos da função vestibular (p = 0,003). Conclusão: Os seis testes clínicos foram capazes de identificar a presença ou não de função vestibular e assimetria da função entre as orelhas de um mesmo indivíduo.

Abstract Introduction: Cochlear implants are undeniably an effective method for the recovery of hearing function in patients with hearing loss. Objective: To describe the preoperative vestibular assessment protocol in subjects who will be submitted to cochlear implants. Methods: Our institutional protocol provides the vestibular diagnosis through six simple tests: Romberg and Fukuda tests, assessment for spontaneous nystagmus, Head Impulse Test, evaluation for Head Shaking Nystagmus and caloric test. Results: 21 patients were evaluated with a mean age of 42.75 ± 14.38 years. Only 28% of the sample had all normal test results. The presence of asymmetric vestibular information was documented through the caloric test in 32% of the sample and spontaneous nystagmus was an important clue for the diagnosis. Bilateral vestibular areflexia was present in four subjects, unilateral arreflexia in three and bilateral hyporeflexia in two. The Head Impulse Test was a significant indicator for the diagnosis of areflexia in the tested ear (p = 0.0001). The sensitized Romberg test using a foam pad was able to diagnose severe vestibular function impairment (p = 0.003). Conclusion: The six clinical tests were able to identify the presence or absence of vestibular function and function asymmetry between the ears of the same individual.

Abstract Introduction Usher syndrome (US) is an autosomal recessive disorder characterized by hearing loss and progressive visual impairment. Some deaf Usher syndrome patients learn to communicate using sign language. During adolescence, as they start losing vision, they are usually referred to cochlear implantation as a salvage for their new condition. Is a late implantation beneficial to these children? Objective The objective of this study is to describe the outcomes of US patients who received cochlear implants at a later age. Methods This is a retrospective study of ten patients diagnosed with US1. We collected pure-tone thresholds and speech perception tests from pre and one-year post implant. Results Average age at implantation was 18.9 years (5-49). Aided average thresholds were 103 dB HL and 35 dB HL pre and one-year post implant, respectively. Speech perception was only possible to bemeasured in four patients preoperatively, who scored 13.3; 26.67; 46% vowels and 56% 4-choice. All patients except one had some kind of communication. Two were bilingual. After one year of using the device, seven patients were able to perform the speech tests (from four-choice to close set sentences) and three patients abandoned the use of the implant. Conclusion We observed that detection of sounds can be achieved with late implantation, but speech recognition is only possible in patients with previous hearing stimulation, since it depends on the development of hearing skills and the maturation of the auditory pathways.

Abstract Introduction After mastoidectomy, patients usually complain of bone depressions in the retroauricular region in the surgical site, especially in procedures that require extensive cortical resections. This causes inconveniences such as difficulty wearing glasses, cleaning, and aesthetics complaints. Objective This study aims to describe a vascularized flap surgical technique that uses the mastoid cortical bone adhered to the periosteum, which is pedicled on the anterior portion and repositioned at the end of the surgery. This ensures the coverage of the mastoid cavity generated by surgery and prevents ear retraction into the cavity. This preliminary report describes the technique and intraoperative and immediate postoperative complications. Methods After retroauricular incision, periosteal exposure is performed. A U-shaped incision is required for the procedure and delimits a periosteum area appropriate to the size of the mastoidectomy. The cortical bone is opened using a 2.5 mm drill around the perimeter of the “U,” at a 3 mmdepth. A chisel is introduced through the surface cells of the mastoid, and a hammer evolves into the anterior direction. The flap is lifted, leaving the periosteum adhered to it and forming a cap. The flap is anteriorly fixed to not hinder the surgery, and repositioned at the end. The periosteum is then sutured to the adjacent periosteum. Results The first 14 cases had no intraoperative complications and were firm and stable when digital pressure was applied during the intraoperative and immediate postoperative periods. Conclusion The osteoplastic flap pedicle is a safe and simple procedure, with good results in the immediate postoperative period.

RESUMO Objetivo: verificar a aquisição de vocabulário em crianças surdas, usuárias de implante coclear, bem como os fatores que influenciam esse desenvolvimento. Métodos: foi aplicada a parte de vocabulário do teste de linguagem infantil ABFW em 20 crianças usuárias de implante coclear por no mínimo três anos. Além disso, foi avaliada a participação familiar no desenvolvimento dessas crianças. Resultados: foi observado que as crianças implantadas apresentam possibilidade de alcançar o desenvolvimento normal de vocabulário, quando comparadas às crianças ouvintes, a depender de diversos fatores. O fator que apresentou influência estatisticamente significante no vocabulário foi a participação familiar, sendo que quanto maior o envolvimento da família no processo terapêutico, melhores os resultados no teste de vocabulário. Conclusão: as crianças implantadas podem apresentar desempenho similar às crianças ouvintes no teste de vocabulário, a depender das variáveis que transcendem a idade à implantação ou mesmo o tempo de uso do implante coclear. A estimulação/ participação familiar no desenvolvimento das crianças se mostrou de extrema importância no desenvolvimento da linguagem oral.

ABSTRACT Objective: to verify whether children with cochlear implants (CI) acquire vocabulary at the same pace as normally hearing children, and which factors influence their acquisition. Methods: the vocabulary test of the ABFW was performed on 20 children who had been using the cochlear implant for at least three years. Historical information, such as age at time of implant, hearing age (i.e., at time of implant use), and family participation in the rehabilitation process, was gathered from patients’ files. Correlation statistical analysis was then performed. Results: it was observed that children with CI may acquire vocabulary similar to that of hearing children, depending on many aspects. The age at time of implantation and hearing age did not significantly correlate to the vocabulary results. The factor that demonstrated statistical significance was family participation, which showed a positive correlation: the more the family was involved in the rehabilitation process, the better the children’s results on the vocabulary test. Conclusion: it was, thus, possible to conclude that children with CI develop their vocabulary in a similar manner as hearing children, depending on factors that transcend the child’s age at time of implantation and hearing age. Family participation, in the rehabilitation process, was shown to be of critical importance in the child’s vocabulary development.

RESUMO Objetivo Avaliar a satisfação e qualidade de vida em usuários de Implante Auditivo de Tronco Cerebral. Método Trata-se de um estudo transversal e descritivo realizado na Divisão de Clínica Otorrinolaringológica do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, Brasil. Para a realização da pesquisa, 19 usuários de implante auditivo de tronco cerebral responderam aos seguintes questionários: KINDLR (Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents) para crianças e adolescentes, pais e/ou cuidadores; o questionário WHOQOL-BREF para os participantes adultos; e o questionário SADL (Satisfaction with Amplification in Daily Life), adaptado culturalmente para o português brasileiro. Resultados A qualidade de vida das crianças usuárias de implante auditivo de tronco cerebral do ponto de vista dos pais apresentou resultados acima da média para o resultado global e para a maioria dos domínios, exceto o domínio de bem-estar emocional. Os adultos apresentaram resultados acima da média para todos os domínios. Com relação à satisfação com o dispositivo, os adultos usuários de implante auditivo de tronco cerebral estavam satisfeitos de modo geral, exceto no que diz respeito à imagem pessoal, e os pais das crianças mostraram insatisfação para todas as subescalas, exceto para a subescala de serviços e custos. Conclusão Os resultados indicaram que, apesar de os pacientes estarem insatisfeitos em alguns aspectos com o dispositivo, de modo geral, a qualidade de vida foi classificada como boa, para a maioria dos aspectos avaliados.

ABSTRACT Purpose To evaluate satisfaction and quality of life of users of Auditory Implant Brainstem. Methods This is a cross-sectional and descriptive study conducted at Divisão de Clínica Otorrinolaringológica of Hospital das Clínicas of Faculdade de Medicina da Universidade de São Paulo, Brazil. For the research, 19 users of an Auditory Brainstem Implant answered the following questionnaires: KINDLR (Questionnaire for Measuring Health-Related Quality of Life in Children and Adolescents), for children and adolescents, their parents and/or caregivers; WHOQOL-BREF questionnaire, for adult participants; and the Satisfaction with Amplification in Daily Life (SADL) questionnaire culturally adapted to Brazilian Portuguese. Results The quality of life of children using Auditory Brainstem Implant from the perspective of their parents showed global results above average, as for most domains, except for the emotional well-being domain. Adults showed results above average for all domains. Regarding satisfaction with the device, the adult users of auditory brainstem implant were satisfied in general, except with regard to personal image. The parents of the children showed dissatisfaction in all subscales, except for the subscale of services and cost. Conclusion The results indicated that although patients are dissatisfied with the device in some aspects, overall the quality of life was rated as good for most of the aspects assessed.
