SUMMARY OBJECTIVE: The primary objective was to analyze and report on the complications that occurred in the cochlear implant surgeries performed at a large philanthropic teaching hospital located in a low-income area of Brazil. METHODS: A historical cohort study that analyzed surgical records of 432 patients of all age groups and both genders who received unilateral cochlear implant in a tertiary referral center that serves only Brazil's Public Health Care System patients, from February 2009 to December 2017. RESULTS: A total of 67 (15.5%) complications occurred in the cochlear implant surgeries, with 21 (5.4%) major complications. Minor complications occurred in 50 (12%) cases. The most frequent major complication was receiver-stimulator displacement (four cases). There were three cases of hardware failure. Only one case of meningitis and one case of facial nerve paralysis (grade VI in House-Brackmann scale) were found. Six patients needed to be explanted due to a major complication. The relative risk of major complications in the population aged 60 years and older was 4.41 (1.53-12.72; 95% confidence interval [CI]). CONCLUSIONS: Elderly patients suffered more complications than younger patients. receiver-stimulator displacement and dizziness were the most frequent complications (major and minor, respectively). The overall complication rates were comparable to those in the literature. Age as an isolated risk factor for complications in cochlear implant surgery is a path to be explored in future observations.

Abstract Objective: To evaluate the impact of the Universal Neonatal Hearing Screening (UNHS) on the age at diagnosis, beginning of treatment, and first cochlear implant surgery. Methods: A retrospective cohort study with children up to 12 years old with bilateral hearing loss were divided into two groups: patients who underwent UNHS and the ones who didn't. The groups were compared according to their age at the beginning of the evaluation at a specialized center, at the beginning of the intervention, and, for the ones who had indication, at the cochlear implant surgery. The group who underwent UNHS was divided between the ones who passed the screening test and the ones who didn't. They were compared according to their ages at the same moments as the first two groups. Results: 135 patients were included. The median age at the first appointment in a specialized center was 1.42 (0.50 and 2.50) years, at the beginning of treatment 2.00 (1.00 and 3.52) years, and the cochlear implant surgery 2.83 (1.83 and 4.66) years. Children who underwent UNHS were younger than those who didn't, at the three evaluated moments (p < 0.001). In a subanalysis, children who passed the UNHS but were later diagnosed with hearing loss reached the first appointment with a specialist and started treatment older than those who failed the tests. Conclusion: Performing UNHS interfered with the timing of deafness diagnosis and treatment. However, children who passed the screening but were later diagnosed with hearing loss were the category with the most important delay.

Abstract Introduction Aminoglycoside, as an antimicrobial medication, also has side-effects on the inner ears, bringing about hearing disorders. Curcumin has been proven to be a strong scavenger against various reactive oxygen species (ROS), and the increase in ROS production is considered to play an important role in the process of hearing disorder. Objective To prove that curcumin is an effective antioxidant to prevent cochlear damage based on malondialdehyde (MDA) expression. Methods The present research used 32 Rattus norvegicus, of the Wistar lineage, randomly divided into 8 groups: negative control, ototoxic control (a single dose of 40 mg/ml of gentamicin via intratympanic injection), 2 groups submitted to ototoxic control + curcumin treatment (100 mg/kg, 200 mg/kg), 2 groups who iunderwent ototoxic control + curcumin treatment for 7 days, and two groups submitted to curcumin treatment as prevention for 3 days + ototoxic induction. Results The results showed that the lowest dosage of curcumin (100 mg/kg) could decrease MDA expression on the cochlear fibroblastic wall of the ototoxic model; however using greater doses of curcumin (200 mg/kg) for 7 days would provide a better effect. Curcumin could also significantly decrease MDA expression when it was administered during the preototoxic exposure. Conclusion Curcumin can be used as a therapy for ototoxic prevention based on the decrease in MDA expression.

Abstract Introduction Tinnitus is the perception of sound in the absence of external sound stimulation. There is a general agreement that it is a direct consequence of irreversible and permanent cochlear damage. Objectives The present work is designed to study the distortion product otoacoustic emissions (DPOAEs) in tinnitus patients with normal hearing in comparison with normal hearing control and to study any possible correlation between DPOAEs recording and patients' complaints. Methods The present study included 80 subjects divided into 2 groups: Control group: consisted of 30 normal-hearing adults not complaining of tinnitus and Study group: consisted of 50 normal-hearing adults complaining of tinnitus. The methodology includes full audiological history, otoscopic examination, basic audiological evaluation, DPOAEs including both DP-gram and DPOAEs input/output functions. Results Basic audiological evaluation showed within normal hearing sensitivity in both groups, however, with significant higher hearing thresholds in tinnitus patients at all frequency ranges. The Tinnitus Handicap Inventory Questionnaire showed mean scores of 35.2 ± 16.9 in the study group. The DP-gram showed higher amplitudes in the control group when compared with tinnitus patients. The DPOAEs input-output functions at different frequencies (1, 2, 4 and 6kHz) also showed higher amplitudes at all frequencies and different input levels. The slope of the I/O function tends to be steeper in tinnitus cases. Conclusion Patients with tinnitus might have neural dysfunction at either the level of the cochlea, as shown in reduced DPOAE levels, and changes in the normal DP-I/O function recorded in the present work.

RESUMO Objetivo caracterizar a produção da fala de crianças e adolescentes usuários de aparelho de amplificação sonora individual (AASI) ou implante coclear (IC) de um programa de reabilitação auditiva. Métodos estudo observacional transversal. Foram analisadas amostras de fala de 15 participantes de um programa de reabilitação auditiva, que consistiam na prova de fonologia do ABFW (ABFW - Teste de Linguagem Infantil nas Áreas de Fonologia, Vocabulário, Fluência e Pragmática) e na fala espontânea, adaptada do Protocolo de Avaliação de Voz do Deficiente Auditivo. Foi aplicado o teste de Wilcoxon para comparar os índices de Porcentagem de Consoantes Corretas (PCC) e Porcentagem de Consoantes Corretas revisado (PCC-r) das provas de fonologia e o teste de Mann-Whitney para comparar os referidos índices, em relação aos graus de inteligibilidade da fala espontânea. Também foi analisada a variabilidade de produção dos fonemas das provas de fonologia. Resultados verificou-se desvio leve nos índices de PCC e PCC-r para as provas de fonologia, com escores superiores para o PCC-r. Os participantes com médias maiores que 85% alcançaram inteligibilidade "Boa" e participantes com médias entre 85% e 50% apresentaram inteligibilidade "Regular/Insuficiente". Os usuários de AASI não produziram adequadamente os fonemas /s/, /z/, /Ʒ/ /ɲ/, /l, /ʎ/, arquifonema /S/ e arquifonema /R/ e os usuários de IC, os fonemas /ʎ/ e arquifonema /R/. Conclusão o grupo estudado apresentou desvio leve nos índices de PCC e PCC-r, com médias superiores, quando considerada a distorção como acerto. Participantes com inteligibilidade "Boa" apresentaram maiores escores de PCC e PCC-r. Usuários de AASI não produziram fonemas fricativos adequadamente. Foram observadas produções com variação linguística social e regional.

ABSTRACT Purpose To characterize the speech production of children and adolescents from an auditory rehabilitation program who use hearing aids (HA) or cochlear implant (CI). Methods Cross-sectional observational study. Speech samples from 15 participants of a hearing rehabilitation program were analyzed through the phonology test of the ABFW Test and spontaneous conversation, which were adapted from the Protocol for the Evaluation of Voice in Subjects with Hearing Impairment. The Wilcoxon test was used to compare the Percentage of Consonants Correct (PCC) and the Percentage of Consonants Correct-revised (PCC-r) indexes of the phonology test, and the Mann-Whitney test was used to compare these indexes to the degrees of intelligibility of spontaneous conversation. The variability of production of the phonemes of the phonology tests was also analyzed. Results There was a mild deviation in the PCC and PCC-r indexes for the phonology tests, with higher scores for the PCC-r. Participants with averages greater than 85% achieved "Good" intelligibility, and participants with averages between 85% and 50% had "Regular/Insufficient" intelligibility. The HA users did not properly produce the phonemes /s/, /z/, /Ʒ/ /ɲ/, /l, /ʎ/, the archiphoneme /S/, and the archiphoneme /R/. The CI users did not properly produce the phonemes /ʎ/ and the archiphoneme /R/. Conclusion The group had a mild deviation in the PCC and PCC-r indexes, with higher means when the distortion was considered correct. Participants with "Good" intelligibility had higher PCC and PCC-r scores. HA users did not produce fricative phonemes properly. There were productions with a social and regional linguistic variation.

Critérios de seleção Foram incluídos estudos sobre o FFR em usuários de implante coclear ou que os comparassem à indivíduos com audição normal, sem restrição de idade. Foram excluídos estudos secundários e experimentais. Não houve restrição de idioma e ano de publicação. Análise dos dados Os dados foram analisados e redigidos de acordo com as etapas do Preferred Reporting Items for Systematic Reviews and Meta-Analyse (PRISMA) 2020. Para análise da qualidade metodológica foi utilizado o instrumento Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross Sectional Studies. As divergências foram resolvidas por um terceiro pesquisador. Resultados Seis estudos atenderam aos critérios de inclusão. Apenas um estudo foi do tipo comparativo com grupo controle de indivíduos com audição normal. As variações nos parâmetros de aquisição foram comuns e as análises predominaram no domínio do tempo. Usuários de implante coclear apresentaram diferenças nos resultados do FFR quando comparados a indivíduos com audição normal, considerando a literatura existente. A maioria dos artigos teve baixa qualidade metodológica. Conclusão Não existe padronização de um protocolo de aquisição e análise para o FFR em usuários de implante coclear. Os resultados são de alto risco de viés.

ABSTRACT Purpose To characterize the acquisition parameters, analysis, and results of the frequency-following response (FFR) in cochlear implant users. Research strategies The search was conducted in Cochrane Library, Latin American and Caribbean Health Sciences Literature (LILACS), Ovid Technologies, PubMed, SciELO, ScienceDirect, Scopus, Web of Science, and gray literature. Selection criteria Studies on FFR in cochlear implant users or that compared them with normal-hearing people, with no restriction of age, were included. Secondary and experimental studies were excluded. There was no restriction of language or year of publication. Data analysis The data were analyzed and reported according to the stages in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), 2020. The methodological quality was analyzed with the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies. Divergences were solved by a third researcher. Results Six studies met the inclusion criteria. Only one study was comparative, whose control group comprised normal-hearing people. The variations in acquisition parameters were common and the analysis predominantly approached the time domain. Cochlear implant users had different FFR results from those of normal-hearing people, considering the existing literature. Most articles had low methodological quality. Conclusion There is no standardized FFR acquisition and analysis protocol for cochlear implant users. The results have a high risk of bias.

ABSTRACT Purpose The study was aimed to investigate the relationship between parental stress and attitude of parents towards the outcomes of cochlear implantation in an Indian scenario. Methods A total of 59 parents of children with cochlear implantation participated in the study. The outcomes of cochlear implant was measured using Parental attitudes of various aspects of cochlear implantation questionnaire and parental stress was measured using parental stress scale. The questionnaires were circulated to participants and data was collected in the form of e-survey. Results The present study showed that the parental stress level was similar among mothers and fathers. Further, the parental attitude towards communication abilities of children and education were positively correlated with the duration of cochlear implantation. Finally, a significant positive correlation was found between the parental stress and the parental attitude towards communication abilities of children and social skills. Conclusion The present study showed a positive relationship between parental stress and parental attitude towards the outcomes of cochlear implantation for aspects of communication abilities and social skills.

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 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 Introduction Individual variability in the language outcomes of children with cochlear implantation (CI) is a major concern. In CI rehabilitation, there is lack of a protocol regarding uniform post-CI language assessment interval duration, which can ensure better understanding of the trajectory of language growth as well as optimize language outcomes by providing feedback in fine tuning the language intervention program. Objective To evaluate the receptive and expressive language in Hindi speaking children with up to 2 years of CI experience using revised receptive-expressive emergent language test-3ed. (REELT-3) at 6 months intervals and to compare it with that of children with normal hearing (NH). Methods The present study included 192 children divided in 2 groups, 96 children with CI (15.8 ± 6.7 months), and 96 age-matched children with NH (22.3 ± 7.9 months). A cross-sectional, prospective study design was used to measure the language ability score (LAS) at an interval of 6 months from the time of implantation (TIA), which is 0 to 6 months, 7 to 12 months, 13 to 18 months, and 19 to 24 months of CI usage. Results The two-way analysis of variance revealed that the LAS after 18 months of CI usage was similar to (F (3, 92) = 8.63, p= 0.19, ηp2 = 0.028) that of the children with NH. However, other demographic factors, for instance, gender (F (3, 92) = 1.73, p= 0.505, ηp2 = 0.002), parent's education, (F (3, 92) = 2.05, p= 0.937, ηp2 = 0.031), and financial background (F (3, 92) = 2.49, p= 0.351, ηp2 = 0.076) had no major impact on language. Conclusion Eighteen months of CI usage duration can potentially stimulate receptive and expressive language up to age-matched children with NH. A protocol of periodic assessment of language, at least of 6 months, may be developed to optimize language outcomes.

RESUMEN Introducción: La cirugía del implante coclear es un método efectivo para la rehabilitación auditiva de los pacientes con hipoacusia neurosensorial severo-profunda, en los que el rendimiento con los audífonos no es suficiente. Aunque la implantación coclear es una técnica segura, es importante conocer sus posibles complicaciones, entre ellas la infección del colgajo o la parálisis facial. Objetivo: Analizar las complicaciones de los pacientes con implante coclear intervenidos en un hospital universitario terciario: El Hospital Universitario Doctor Peset de Valencia, desde enero de 2001 a marzo de 2020. Metodología: Estudio observacional descriptivo de las complicaciones en una muestra de 134 pacientes con implantación coclear en el Hospital Universitario Doctor Peset de Valencia, en un periodo de 20 años. En el análisis estadístico se utilizó estadística descriptiva. Para demostrar diferencias significativas entre variables empleamos el programa R. Se utilizó el test χ2 para proporciones, considerando significativo un valor p < 0.05. Resultados: 134 pacientes fueron implantados. La frecuencia global de complicaciones fue del 17.9%, 4.5% fueron complicaciones mayores y 13.4% fueron complicaciones menores. La complicación más frecuente fue la desactivación o inserción incompleta de algunos electrodos. Discusión: Las proporciones de complicaciones del estudio entran dentro de los rangos encontrados en la literatura (14.9-18.3%). La frecuencia de complicaciones mayores es inferior al 5%, proporción similar a la obtenida en nuestra serie. Conclusiones: El implante coclear es una técnica quirúrgica segura para la rehabilitación de pacientes con hipoacusia severa, aunque no está exenta de riesgo, por lo que se debe conocer sus potenciales complicaciones.

ABSTRACT Introduction: Cochlear implantation is an effective method for hearing rehabilitation in patients with severe neurosensory hearing loss in which hearing aids do not provide good discrimination. Although cochlear implantation is a safe technique, adverse effects related to surgery have been described, including flap infection or facial paralysis. Objective: To analyze the complications of cochlear implanted patients in a tertiary university hospital: The Hospital Universitario Doctor Peset of Valencia, from January 2001 to March 2020. Methodology: This is a descriptive observational study of the complications in a sample of 134 patients with cochlear implant surgery in The Hospital Universitario Doctor Peset of Valencia in a period of 20 years. Descriptive statistics were used in the statistical analysis. To demonstrate significant differences between variables we used the R program. The χ2 test was used for proportions, considering significant a p value < 0.05. Results: 134 patients were implanted. The global frequency of complications was 17.9%, 4.5% were major complications and 13.4% were minor complications. The most frequent complication was inactivation or incomplete insertion of some electrodes. Discussion: Our complication rate is within the range published in the literature (14.9-18.3%). The major complication rate is 5% which is similar to our series. Conclusions: The cochlear implant is a safe surgical technique for the rehabilitation of patients with severe neurosensory hearing loss, although it is not riskless, therefore, one must know that complication are possible.

RESUMEN Fundamento: desde el año 2005 se crea el Programa Cubano de Implantes Cocleares para niños sordos y sordociegos, con prioridad para niños con pérdida sensorial dual. Objetivo: describir el comportamiento de la pérdida sensorial dual en niños del Programa Cubano de Implantes Cocleares. Métodos: se realizó un estudio observacional, descriptivo, retrospectivo de niños con pérdida sensorial dual que recibieron implante coclear entre febrero de 2005 y marzo de 2013 en Cuba. De las historias clínicas y la base de datos del programa fue obtenida la información que permitió elaborar el informe. Con antelación, se ilustran los primeros resultados sobre neuroplasticidad obtenidos con potencial evocado somatosensorial de nervio mediano realizado con parte del protocolo de estudio de investigación preimplante coclear en el Programa Cubano de Implantes Cocleares. Resultados: con el programa se han beneficiado 27 niños con pérdida sensorial dual con implantes cocleares, con cobertura a todas las provincias del país. Seis niños presentaron una enfermedad asociada, predominaron los factores pre/peri-natales y el síndrome de Usher como principales agentes causales de la sordoceguera. La pérdida auditiva fue prelocutiva en 24 niños, confirmada y caracterizada mediante electroaudiometría. Los estudios de imágenes de oídos no mostraron malformaciones. La implantación fue unilateral, sobre todo el oído derecho, sin complicaciones quirúrgicas en ninguno de los niños. Mientras que el estudio de neuroplasticidad evidencia reorganización cortical somestésica en niños con pérdida sensorial dual. Conclusiones: el Programa Cubano de Implantes Cocleares ha logrado un trabajo sostenido en la evaluación e implantación de niños con pérdida sensorial dual, distinguiéndose la investigación sobre neuroplasticidad, la cual ha dado evidencias de representación cortical somestésico preimplante coclear en estos niños. Ello será útil para evaluar la reorganización cortical post-implante coclear y correlacionarlo con el aprovechamiento del uso del implante coclear.

ABSTRACT Background : since 2005 the Cuban Cochlear Implant Program for deaf and deaf-blind children has been created, with priority for children with dual sensory loss. Objective: is to describe the work of the Cuban Cochlear Implant Program with children with dual sensory loss. Methods : a descriptive, retrospective study of children with dual sensory loss who received a cochlear implant between February 2005 and March 2013 in Cuba. The information to conform this descriptive report was obtained from the clinical histories and the database of the program; it also illustrates the first results on neuroplasticity obtained with the somatosensory evoked potential of the median nerve carried out with part of the pre-cochlear implant research study protocol in the Cuban Cochlear Implant Program. Results : the program has benefited 27 children with dual sensory loss with cochlear implants, covering all provinces of the country. Six children presented an associated pathology, with pre/peri-natal factors and Usher Syndrome as the main causal agents of deaf-blindness. Hearing loss was pre-lingual in 24 children, confirmed and characterized by electro-audiometry. No malformations were found in the ear images. The implantation was unilateral, mostly the right ear, without surgical complications in all the children. While the neuroplasticity study shows somesthetic cortical reorganization in children with dual sensory loss. Conclusions : the Cuban Cochlear Implant Program has achieved sustained work in the evaluation and implantation of children with dual sensory loss, a distinctive aspect being the research on neuroplasticity, which has provided evidence of somesthetic cortical representation pre-cochlear implantation in these children. This will be useful to assess cortical reorganization post- cochlear implant and correlate it with the use of the cochlear implant.

A deficiência auditiva é considerada uma das mais incapacitantes. A família de crianças deficientes enfrenta dificuldades inerentes à comunicação, aos conflitos, à afetividade e à integração infantil. Neste estudo, objetiva-se compreender como as mães vivenciaram a maternidade frente à surdez do filho, sob a perspectiva do narcisismo na teoria psicanalítica, num estudo qualitativo. Participaram deste estudo mães de crianças com surdez, em tratamento num serviço de implante coclear de um hospital de referência do Recife. Ao ser recebido pelas mães, o diagnóstico veio acompanhado de sofrimento emocional, impacto e fragilidade, afetando o narcisismo materno. Ainda assim, percebeu-se que as mães ficaram jubilosas ao apontarem a aquisição auditiva dos filhos possibilitada pelo implante coclear, indicando que este dispositivo pôde alinhavar o narcisismo materno, o qual, imaginariamente, recompõe o corpo. Enfatizamos que os profissionais de saúde precisarão respeitar o tempo lógico de elaboração pelo qual as mães passarão frente à surdez do filho.

Hearing deficiency is considered one of the most disabling. The family of disabled children faces inherent difficulties in communication, conflicts, affectivity, and child integration. The aim of this study was to understand how mothers experienced motherhood in the face of the deafness of the child, from the perspective of narcissism in psychoanalytic theory, in a qualitative study. The participants were mothers of deaf children undergoing treatment at a cochlear implant service at a reference hospital in Recife. The diagnosis was received by mothers with emotional suffering, impact and fragility affecting maternal narcissism. However, it was noticed that the mothers were jubilant to point to the children's auditory acquisition made possible by the cochlear implant, indicating that this device could nourish the maternal narcissism, which imaginatively recomposes the body. The health professionals will have to respect the logical time of elaboration, that mothers go through when facing the deafness of the child.

RESUMEN Introducción: el lenguaje oral está basado principalmente en la información acústica. La hipoacusia es la pérdida parcial de la capacidad auditiva. A partir de los 40 decibelios en adelante, su presencia repercute en la adquisición de las funciones del lenguaje y el desarrollo integral del niño. Objetivo: describir la evolución de un caso clínico hipoacúsico con implante coclear, tras la aplicación de una terapia auditivo-verbal. Presentación de caso: se presenta un niño de 10 años y siete meses de edad, con retraso en el desarrollo del lenguaje debido a una Hipoacusia Neurosensorial Bilateral Profunda de presunto origen congénito. Después de ser diagnosticado tempranamente con esta enfermedad, fue incluido en el Programa Nacional de Implante Coclear con vistas a mejorar sus capacidades auditivas y facilitar así la retroalimentación auditiva. Luego de la cirugía se le comenzó a aplicar una terapia auditivo verbal para propiciar la adquisición adecuada de las funciones del lenguaje. Conclusiones: los niños con problemas de audición pueden aprender a escuchar y a hablar mediante un diagnóstico y una intervención temprana, la tecnología apropiada y con la dedicación de padres y terapeutas que comparten la visión de darle voz al futuro del niño. Es importante tener en cuenta que el tratamiento adecuado, la capacidad intelectual de los niños y el ambiente familiar, condicionan la evolución exitosa de las terapias aplicadas.

ABSTRACT Introduction: oral language is mainly based on acoustic information. Hypoacusis is the partial loss of hearing capacity; from 40 decibels and above, its presence has an impact on the acquisition of language functions and the overall development of the child. Objective: to describe the evolution of a clinical case of a hearing impaired patient with cochlear implant after the application of an auditory-verbal therapy. Case report: a 10-year-old and 7 months boy with delayed language development due to a Deep Bilateral Sensorineural Hearing Loss of presumed congenital origin, after being diagnosed early with this disease he was included in the National Cochlear Implant Program in order to improve his hearing abilities and thus facilitate auditory feedback. After surgery, he began to undergo auditory-verbal therapy to promote the proper acquisition of language functions. Conclusions: hearing impaired children can learn to listen and speak through early diagnosis and intervention, appropriate technology and with the perseverance of parents and therapists who share the vision of giving voice to the future of the child. It is important to keep in mind that the appropriate treatment, the intellectual capacity of children and the family environment condition the successful evolution of the therapies applied.

Abstract Introduction The hair cells of the cochlea and the vestibulum are closely connected and may be susceptible to the same noxious factors. The relationship between their function has been a continuing field of investigation. The indications for cochlear implantation have been broadened and now include the patients with partial deafness. This raises the question of their vestibular status. Objective The aim of the study was to investigate whether there is any difference between the vestibular function of patients with low frequency residual hearing and those with totally deaf ears. Methods A total of 360 ears with profound sensorineural hearing loss were analysed before cochlear implantation. The patients were divided into four groups, according to their low frequency residual hearing (Group 1 ‒ normal or slightly elevated low frequency residual hearing; Group 2 ‒ elevated threshold but still usable hearing at low frequencies; Group 3 - non-functional residual hearing; Group 4 ‒ no detectable hearing threshold within the limits of the audiometer). The patients underwent vestibular tests: cervical vestibular evoked myogenic potential, ocular vestibular evoked myogenic potential, caloric test and video-head impulse test. Results The rates of elicited responses in cervical vestibular evoked myogenic potential were as follows: in Group 1 (59.3 %); Group 2 (57.5 %); Group 3 (35.2 %); Group 4 (7.7 %). For ocular vestibular evoked myogenic potential the percentage of correct outcomes was: Group 1 (70.8 %); Group 2 (56.0 %); Group 3 (40.0 %); Group 4 (14.3 %). For the caloric test we counted normal responses in 88.9 % of Group 1; 81.6 % of Group 2; 57.9 % of Group 3; 53.3 % of Group 4. For video-head impulse test we also found markedly better results in Group1, followed by Group 2, and much worse in Group 3 and 4. Conclusion Patients with partial deafness not only have a better cochlea but also better vestibular function, which needs to be protected. In summary, the better the low frequency residual hearing, the better the vestibular status.

Resumo Introdução As células ciliadas da cóclea e do vestíbulo estão intimamente ligadas e podem ser suscetíveis aos mesmos fatores nocivos. A relação entre suas funções tem sido um campo de investigação há muito tempo. As indicações para implante coclear foram ampliadas e agora incluem os pacientes com surdez parcial. Isso levanta a questão de sua condição vestibular. Objetivo Investigar se existe alguma diferença entre a função vestibular de pacientes com audição residual de baixa frequência e aqueles com surdez total. Método Foram analisadas antes do implante coclear 360 orelhas com perda auditiva neurossensorial profunda. Os pacientes foram divididos em quatro grupos, de acordo com a audição residual de baixa frequência (Grupo 1 - audição residual de baixa frequência normal ou levemente elevada; Grupo 2 - limiar auditivo elevado, mas ainda usável em baixas frequências; Grupo 3 - audição residual não funcional; Grupo 4 - sem limiar auditivo detectável dentro dos limites do audiômetro). Os pacientes foram submetidos a testes vestibulares: potencial evocado miogênico vestibular cervical, potencial evocado miogênico vestibular ocular, prova calórica e teste do impulso cefálico com vídeo. Resultados As taxas de respostas obtidas no potencial evocado miogênico vestibular cervical foram as seguintes: no Grupo 1 (59,3%); Grupo 2 (57,5%); Grupo 3 (35,2%); Grupo 4 (7,7%). Para o potencial evocado miogênico vestibular ocular, o percentual de resultados corretos foi: Grupo 1 (70,8%); Grupo 2 (56,0%); Grupo 3 (40,0%); Grupo 4 (14,3%). Para a prova calórica, contamos respostas normais em 88,9% do Grupo 1; 81,6% do grupo 2; 57,9% do Grupo 3; 53,3% do Grupo 4. Para o teste do impulso cefálico com vídeo, também encontramos resultados significativamente melhores no Grupo 1, seguidos pelo Grupo 2, e muito piores nos Grupos 3 e 4. Conclusão Pacientes com surdez parcial não só apresentam uma função coclear melhor, mas também melhor função vestibular, que precisa ser protegida. Em resumo, quanto melhor for a audição residual de baixa frequência, melhor a condição vestibular.

Abstract Introduction Tinnitus is a frequent symptom in cochlear implant patients, often reported as persistent and disabling in implant candidates. Tinnitus is rarely considered in the preoperative evaluation of patients who are eligible for cochlear implantation. Many studies have shown that a cochlear implant leads to a significant change in the perception of tinnitus. Objective To identify evidence in the scientific literature indicating that cochlear implant in eligible patients with tinnitus can improve tinnitus perception. Methods One hundred forty articles were found from nine databases, and 20 articles from the gray literature mentioned the relationship between cochlear implant and tinnitus perception in patients eligible for cochlear implant. The PICOS (population, intervention, comparison, and outcome) strategy, was used to define the eligibility criteria. The studies that met the inclusion criteria for this second step were included in a qualitative synthesis, and each type of study was analyzed using the Joanna Briggs Institute critical appraisal checklist for quasi-experimental studies and the Joanna Briggs Institute critical appraisal checklist for randomized clinical trials. Results The full texts of 11 articles were read, and 6 studies were selected for the meta-analysis. The total sample size in the evaluated articles was 136 patients with tinnitus who were eligible for cochlear implantation. Conclusions Taken together, these findings support the feasibility of cochlear implantation to reduce the perception of tinnitus, thus providing a new perspective in the treatment of tinnitus in patients with hearing loss who are candidates for cochlear implantation.

Resumo Introdução Zumbido é um sintoma frequente em pacientes com implante coclear, comumente relatado como persistente e incapacitante em candidatos ao procedimento. Entretanto, o zumbido raramente é considerado na avaliação pré-operatória de pacientes elegíveis para o implante coclear. Muitos estudos têm demonstrado que o implante coclear leva a uma mudança significativa na percepção do zumbido. Objetivo Identificar evidências na literatura científica que indiquem que o implante coclear em pacientes com zumbido pode melhorar a percepção. Método Foram encontrados 140 artigos em nove bases de dados e 20 artigos da literatura cinzenta mencionaram a relação entre o implante coclear e a percepção do zumbido em pacientes elegíveis para o procedimento. A estratégia PICOS (população, intervenção, comparação e desfecho) foi usada para definir os critérios de elegibilidade. Os estudos que atenderam aos critérios de inclusão para esta segunda etapa foram incluídos em uma síntese qualitativa e cada tipo de estudo foi analisado com a critical appraisal checklist for quasi-experimental studies e a critical appraisal checklist for randomized clinical trials do Joanna Briggs Institute. Resultados Foram lidos os textos completos de 11 artigos e selecionados 6 estudos para a metanálise. O tamanho total da amostra dos artigos avaliados foi de 136 pacientes com zumbido, elegíveis para o implante coclear. Conclusões Em conjunto, esses achados apoiam a viabilidade do implante coclear para reduzir a percepção do zumbido, proporcionam uma nova perspectiva no tratamento do zumbido em pacientes com deficiência auditiva candidatos a esse procedimento.

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.

Abstract Introduction Cochlear implants have been proposed for cases of unilateral hearing loss, especially in patients with tinnitus impairment. Several studies have shown that they result in definite improvement of sound localization and speech understanding, both in quiet and noisy environments. On the other hand, there are few references regarding cochlear implants in patients whose better ears present hearing loss. Objective To report the audiological outcomes of three patients with unilateral deafness, in whom the better ears presented hearing losses, submitted to cochlear implants. Methods Three patients with unilateral profound hearing loss underwent a cochlear implant performed by the same surgeon. Results The patients' data are presented in detail. Conclusion The indications for cochlear implants are becoming more diverse with the expansion of clinical experience and the observation that they definitely help patients with special hearing problems.

Abstract Introduction Loudness perception is considered important for the perception of emotions, relative distance and stress patterns. However, certain digital hearing devices worn by those with hearing impairment may affect their loudness perception. This could happen in devices that have compression circuits to make loud sounds soft and soft sounds loud. These devices could hamper children from gaining knowledge about loudness of acoustical signals. Objective To compare relative loudness judgment of children using listening devices with age-matched typically developing children. Methods The relative loudness judgment of sounds created by day-to-day objects were evaluated on 60 children (20 normal-hearing, 20 hearing aid users, & 20 cochlear implant users), utilizing a standard group comparison design. Using a two-alternate forced-choice technique, the children were required to select picturized sound sources that were louder. Results The majority of the participants obtained good scores and poorer scores were mainly obtained by children using cochlear implants. The cochlear implant users obtained significantly lower scores than the normal-hearing participants. However, the scores were not significantly different between the normal-hearing children and the hearing aid users as well as between the two groups with hearing impairment. Conclusion Thus, despite loudness being altered by listening devices, children using non-linear hearing aids or cochlear implants are able to develop relative loudness judgment for acoustic stimuli. However, loudness growth for electrical stimuli needs to be studied.
