Como a judicialização da cirurgia de implante coclear impacta o Sistema Único de Saúde / How the judicialization of cochlear implant surgery impacts the Unified Health System

RESUMO Objetivo Descrever o impacto da judicialização na realização da cirurgia de implante coclear no Sistema Único de Saúde do Brasil, incluindo o serviço público e a saúde suplementar. Métodos Foi realizado um levantamento documental de acórdãos de todos os tribunais nacionais e a jurisprudência dominante, voltados à cirurgia do implante coclear no Sistema Único de Saúde, no período de 2007 a 2019, por meio da Plataforma Jusbrasil, utilizando o termo "implante coclear" para realização da busca. Também foi realizado um levantamento na plataforma DATASUS (Departamento de Informação do Sistema Único de Saúde) sobre quantos procedimentos de implante coclear unilateral e bilateral foram realizados no mesmo período. Resultados De acordo com o DATASUS, no período de 2008 a 2019 foram realizados 8.857 procedimentos de cirurgia de implante coclear pelos entes públicos ou pelas operadoras dos planos de saúde no país. Com relação à judicialização para solicitação da cirurgia do implante coclear, unilateral ou bilateral, foram encontrados 216 processos, representando 2,43% dos casos. Conclusão A judicialização da saúde, quando se considera a cirurgia do implante coclear, tem representado uma parcela mínima dos casos, o que demonstra baixo impacto no orçamento público e não tem expressiva ação na organização do Sistema Único de Saúde.

ABSTRACT Purpose To describe the impact of Judicialization on the performance of Cochlear Implant (CI) surgery in the Brazilian Unified Health System (SUS), including the public service and supplementary health. Methods A documentary survey of judgments of all National Courts and the Dominant Jurisprudence focused on CI surgery in the SUS from 2007 to 2019 was carried out through the Jusbrasil Platform using the term "cochlear implant" to carry out the search. A survey was also carried out on the DATASUS platform on how many uni and bilateral CI procedures were performed in the same period. Results According to DATASUS, from 2008 to 2019, 8,857 CI surgery procedures were performed by Public Entities or Health Plan Operators in the country. With regard to Judicialization, for requesting unilateral or bilateral CI surgery, a total of 216 processes were found, representing a total of 2.43% of Judicialization of Cochlear Implant (CI) surgery. Conclusion In view of the data, it is possible to perceive that the Judicialization of Health when we consider the CI surgery has represented a small portion of the cases, which does not demonstrate a large impact on the public budget and does not have an impact on the organization of the SUS.

Self-Reported Voice-Related Quality of Life in Cochlear Implant Users

Objective: The aim of this study was to identify if cochlear implant (CI) users are perceiving a decrease in life quality due to voice problems. This study evaluated 43 CI user's perception of their voice and how it affects their quality of life through a survey. Approach: Forty-three CI users responded to a survey regarding their demographics, details about their CI, the Hearing Health Quick Test (HHQT), the Voice Related Quality of Life (V-RQOL), and the Voice Handicap Index-10 (VHI-10). The survey responses were analyzed using univariate linear regression analysis. Results: Few of the CI users scored below the cut off for normal voice related quality of life. CI users averaged 93.4 out of 100 on the V-RQOL and only four scored abnormally for the VHI-10. Lower scores on the V-RQOL were correlated with the participants having an associate degree and with participants visiting friends, family, and neighbors less often due to hearing loss. The VHI-10 scores were correlated with gender, education levels, difficulty in social situations due to hearing loss, noise exposure, and tinnitus. Limitations of the study: The small n was the primary limitation of this study. Originality: This study was one of the first to examine the voice-related quality of life in CI users. Conclusions: Overall, respondents did not perceive much voice-related difficulty. However, they were more likely to perceive voice-related difficulty if they experienced difficulty hearing in noise and avoided social situations due to hearing loss.

Objetivo: Este estudio identificó si los usuarios de implantes cocleares (IC) están percibiendo una disminución en la calidad de su vida debido a problemas de voz. Además, evaluó la percepción de la voz de 43 usuarios de IC y cómo afecta su calidad de vida a través de una encuesta. Enfoque: Cuarenta y tres usuarios de IC respondieron a una encuesta sobre su demografía, detalles sobre su IC, la Hearing Health Quick Test (HHQT), la Voice Related Quality of Life (V-RQOL) y el Voice Handicap Index-10 (VHI-10). Las respuestas de la encuesta se analizaron mediante un análisis de regresión lineal univariado. Resultados: Pocos usuarios de IC puntuaron por debajo del límite para calidad de vida relacionada con la voz. El promedio V-RQOL fue de 93,4/100; solo 4 participantes tuvieron puntuación anormal en VHI-10. Las bajas puntuaciones en V-RQOL se correlacionaron con título de asociado y menos visitas por pérdida auditiva; las puntuaciones VHI-10, con sexo, educación, dificultad en situaciones sociales, exposición al ruido y tinnitus. Limitaciones del estudio: La pequeña n fue la principal limitación de este estudio. Originalidad: Este estudio fue uno de los primeros en examinar la calidad de vida relacionada con la voz en usuarios de CI. Conclusiones: En general, los encuestados no percibieron mucha dificultad relacionada con la voz. Sin embargo, era más probable que percibieran dificultades relacionadas con la voz si tenían dificultades para oír en ruido y evitaban situaciones sociales debido a la pérdida auditiva.

The P300 Auditory Evoked Potential in Cochlear Implant Users: A Scoping Review

Abstract Introduction The P300 auditory evoked potential is a long-latency cortical potential evoked with auditory stimulation, which provides information on neural mechanisms underlying the central auditory processing. Objectives To identify and gather scientific evidence regarding the P300 in adult cochlear implant (CI) users. Data Synthesis A total of 87 articles, 20 of which were selected for this study, were identified and exported to the Rayyan search software. Those 20 articles did not propose a homogeneous methodology, which made comparison more difficult. Most articles (60%) in this review compare CI users with typical hearing people, showing prolonged P300 latency in CI users. Among the studies, 35% show that CI users present a smaller P300 amplitude. Another variable is the influence of the kind of stimulus used to elicit P300, which was prolonged in 30% of the studies that used pure tone stimuli, 10% of the studies that used pure tone and speech stimuli, and 60% of the studies that used speech stimuli. Conclusion This review has contributed with evidence that shows the importance of applying a controlled P300 protocol to diagnose and monitor CI users. Regardless of the stimuli used to elicit P300, we noticed a pattern in the increase in latency and decrease in amplitude in CI users. The user's experience with the CI speech processor over time and the speech test results seem to be related to the P300 latency and amplitude measurements.

Implantación coclear en pacientes de edad avanzada: Resultados auditivos

Introducción: El envejecimiento de la población, así como la ampliación en las indicaciones de implantación, hace que cada día haya más pacientes implantados mayores de 65 años, lo que supone un reto a nivel de ajuste y optimización auditiva. Se ha constatado que la implantación coclear en pacientes de edad avanzada generalmente conduce a una mejoría, tanto auditiva como en la neurocognición, la depresión, el aislamiento social, la actividad física y la calidad de vida. Objetivo: Los objetivos de este estudio son valorar las características de los pacientes implantados a partir de 65 años en un centro terciario, analizar los beneficios e identificar particularidades clínicas en este grupo de pacientes. Material y Método: Se llevó a cabo un estudio retrospectivo con un seguimiento de 5 años postcirugía de pacientes con implante MED-EL y se realizó una visita preoperatoria y un seguimiento con audiometría en campo libre y audiometría verbales postquirúrgica al año, 3 años y 5 años postquirúrgico. Resultados: Se incluyó a 16 pacientes implantados unilateralmente. La edad media inicio pérdida fue de 36,75 años. La edad media de cirugía fue de 71,44 años. Los resultados auditivos fueron satisfactorios, con una media de audiometría en campo libre de 44,33 dB al año, 43,33 dB a los 3 años y 41,66 dB a los 5 años. El resultado en las audiometrías verbales (test de bisílabos y test de frases) fue mejor en el grupo de pacientes con adaptación bimodal. Conclusión: En nuestra experiencia, la implantación coclear en ≥65 años sí que logra mejorar las capacidades auditivas medidas, tanto en audiometría de campo libre como en pruebas verbales. La adaptación bimodal mejora los resultados auditivos, a pesar de la dificultad de procesamiento de los dos estímulos diferentes.

Introduction: The aging of the population, as well as the expansion in the indications for implantation means that every day there are more implanted patients over 65 years of age, which represents a challenge in terms of hearing adjustment and optimization. Cochlear implantation in elderly patients has been found to generally lead to improvements in hearing and neurocognition, depression, social isolation, physical activity, and quality of life. Aim: The objectives of this study are to assess the characteristics of patients over 65 years of age implanted in a tertiary center, analyze the benefits and identify clinical particularities in this group of patients. Material and Method: A retrospective study was carried out with a 5-year post-surgery follow-up of patients with a MED-EL implant, and a preoperative visit and follow-up with free-field audiometry and post-surgical speech audiometry were performed at one year, 3 years and 5 years post-surgery. Results: Sixteen unilaterally implanted patients were included. The mean age at onset of loss was 36.75 years. The mean age at surgery was 71.44 years. Hearing results were satisfactory, with a mean free field audiometry of 44.33 dB at one year, 43.33 dB at 3 years, and 41.66 dB at 5 years. The result in the verbal audiometries (disyllable test and sentence test) was better in the group of patients with bimodal adaptation. Conclusión: In our experience, cochlear implantation in patients ≥ 65 years of age does manage to improve hearing capacities measured both in free-field audiometry and in verbal tests. Bimodal adaptation improves auditory results, despite the difficulty ofprocessing the two different stimuli.

Análise de limiares tonais de crianças submetidas ao reimplante: seguimento de 10 anos / Analysis of aided thresholds in children who have undergone cochlear reimplantation: a ten-year follow-up

RESUMO Objetivo Caracterizar os limiares auditivos nas frequências de 500, 1000, 2000 e 4000 Hz em crianças submetidas ao reimplante com follow-up de no mínimo 10 anos. Método Revisão retrospectiva de prontuários de crianças submetidas a cirurgia de reimplante há pelo menos 10 anos. Foram avaliados os limiares auditivos obtidos na audiometria tonal liminar em campo livre com o implante coclear nas frequências de 500, 1000, 2000 e 4000 Hz em quatro momentos distintos: 1 (antes da falha), 2 (ativação), 3 (cinco anos após o reimplante) e 4 (dez anos após o reimplante, independentemente do tempo de uso do uso do 2o IC) em pacientes com follow-up de no mínimo 10 anos. Resultados Avaliando-se pacientes submetidos ao reimplante, observou-se que os limiares de 500, 1000, 2000, 4000 Hz apresentaram-se a longo prazo semelhante àqueles obtidos nos pacientes implantados somente uma única vez, não apresentando prejuízo assim na detecção dos sons. Conclusão O reimplante não teve efeito de longo prazo sobre os limiares auditivos obtidos em crianças que se submeteram a esta cirurgia por falha do componente interno.

ABSTRACT Purpose To characterize hearing thresholds at frequencies of 500, 1000, 2000 and 4000 Hz in children undergoing reimplantation with a follow-up of at least 10 years. Methods Retrospective review of medical records of children who underwent reimplantation surgery for at least 10 years. The auditory thresholds obtained in free-field pure tone audiometry with the cochlear implant were evaluated at frequencies of 500, 1000, 2000 and 4000 Hz at four different times: 1 (before failure), 2 (activation), 3 (five years after reimplantation) and 4 (ten years after reimplantation, regardless of the time of use of the 2nd CI) in patients with a follow-up of at least 10 years. Results Evaluating patients who underwent reimplantation, it was observed that the thresholds of 500, 1000, 2000, 4000 Hz were similar in the long term to those obtained in patients who were implanted only once, thus not presenting damage in the detection of sounds. Conclusion Reimplantation had no long-term effect on the hearing thresholds obtained in children who underwent this surgery due to internal component failure.

Brazilian Society of Otology task force - Vestibular Schwannoma - evaluation and treatment

Abstract Objective: To review the literature on the diagnosis and treatment of vestibular schwannoma. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: (1) Diagnosis - audiologic, electrophysiologic tests, and imaging; (2) Treatment - wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. Conclusions: Decision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.

Evaluation of Verbal Working Memory and Phonemic Analysis Skills in Adolescents with Cochlear Implant

Abstract Introduction Adolescents with cochlear implants may have difficulty developing language and memory abilities. Objective The primary objectives of this study are (1) to evaluate the language skills and verbal working memory performance of early and late diagnosed-intervened cochlear implanted adolescents and (2) to investigate the relationship between the verbal working memory and phonemic analysis skills in adolescents with cochlear implant. Methods This study included 72 participants with cochlear implant aged between 10 and 18 years. The participants were divided into two groups; those who had first hearing aid at the age of 6 months at the latest and had a first cochlear implant in at least one ear at the latest at 24 months were included in the early group, all the others were in the late group. The phonemic analysis test, a subtest of the test of language development: Primary, 4th edition (TOLD: P-4) - Turkish version, was used to assess language-based abilities, and the meaningless word repetition (MWR) test was utilized to assess verbal working memory. Results The adolescents with cochlear implants who received early diagnosis and intervention performed statistically significantly better in phonemic analysis scores and verbal working memory tests (p < 0.001). A statistically significant relationship was found between phonemic analysis and verbal working memory skills (Pearson, r = 0.567 and r = 0.659, p < 0.001). Conclusions Rehabilitation of phonological skills can contribute to the development of verbal working memory in adolescents with cochlear implants. There is a need for further studies on this issue with more detailed tests.

Benefits of Bimodal Stimulation to Speech Perception in Noise and Silence

Abstract Introduction Understanding all the benefits of bimodality with self-assessment questionnaires on the effect of hearing on quality of life is still necessary. Objective To present whether bimodality still offers hearing benefits to the population who uses acoustic stimulation associated with electrical stimulation. Methods The present study included 13 participants aged between 16 and 80 years old who were users of cochlear implants from Cochlear Corporation and hearing aids. All patients underwent the Hearing in Noise Test, and their visual analog scale score was obtained. Four-tone means were collected, and the participants answered the Speech, Spatial and Hearing Qualities questionnaire. Results Bimodal users had an average sentence recognition rate of 76.0% in silence and 67.6% in fixed noise, and the signal-to-noise ratio in adaptive noise was +2.89dB. In addition, a lower level of difficulty was observed in the test using the visual analog scale. The domain with the highest average was auditory qualities (6.50), followed by spatial hearing (6.26) and hearing for speech (5.81). Individuals with an average between 50 and 70 dB of hearing level showed better sentence recognition in silence and noise. Conclusion Bimodal stimulation showed benefits for users with different degrees of hearing loss; however, individuals who presented greater hearing residue had better performance in speech recognition with noise and in silence in addition to a good perception of hearing quality.

Implantes cocleares ópticos: una herramienta promisoria de tratamiento para la hipoacusia / Optical cochlear implants: a promising treatment tool for hearing loss

La hipoacusia afecta a más de 1.500 millones de personas mundialmente. Los principales medios de rehabilitación usados son los audífonos e implantes cocleares (IC). El IC eléctrico convierte el sonido en impulsos eléctricos que estimulan, directamente, a las neuronas del ganglio espiral para proveer sensación auditiva. Tiene como desventaja una amplia dispersión espacial de la corriente, limitando la resolución espectral y el rango dinámico de codificación sonoro, lo que conduce a una mala comprensión del habla en entornos ruidosos y mala apreciación de la música. En los últimos años se ha estudiado utilizar estimulación óptica en vez de eléctrica, pues emite estímulos con mayor selectividad espacial. Se han descrito IC ópticos usando luz infrarroja y otros con métodos de optogenética, estos últimos requieren de la expresión de proteínas fotosensibles inducidas por virus adenoasociados. Se ha visto que la selectividad espectral de la estimulación optogenética es indistinguible de la acústica, y permitió tasas de disparo casi fisiológicas con buena precisión temporal hasta 250 Hz de estimulación. Estudios que compararon un sistema de IC óptico con uno eléctrico concluyen que el uso de optogenética permitiría una restauración de la audición con una selectividad espectral mejorada en comparación con un IC eléctrico.

Hearing loss affects more than 1.5 billion people worldwide. The main means of rehabilitation used are hearing aids and cochlear implants (CI). The electrical CI converts sound into electrical impulses that directly stimulate neurons in the spiral ganglion to provide auditory sensation; it has the disadvantage of a wide spatial dispersion of the current, limiting the spectral resolution and the dynamic range of sound coding, which leads to a poor understanding of speech in noisy environments and a poor appreciation of music. In recent years, the use of optical stimulation instead of electrical stimulation have been studied since it emits stimuli with greater spatial selectivity. Optical CIs have been described using infrared light and others using optogenetic methods, the latter requiring the expression of photosensitive proteins induced by adeno-associated viruses. The spectral selectivity of optogenetic stimulation has been found to be indistinguishable from acoustic stimulation and allowed near-physiological firing rates with good temporal accuracy up to 250 Hz stimulation. Studies comparing an optical and an electrical CI system conclude that the use of optogenetics would allow hearing restoration with improved spectral selectivity compared to an electrical CI.

Electrococleografía en implante coclear / Electrocochleography in cochlear implant

La electrococleografía es una técnica electrofisiológica desarrollada en modelos animales hace más de 90 años. En la actualidad se utiliza en la práctica clínica en audiolo-gía y otoneurología, ya que permite evaluar la función coclear, a través del registro del potencial microfónico coclear, y la funcionalidad del nervio auditivo por medio del registro del potencial de acción compuesto. Debido al avance de la tecnología de los implantes cocleares, actualmente existe la posibilidad de realizar mediciones clínicas a tiempo real con electrococleografía intraoperatoria, por lo que se puede monitorizar la función auditiva residual durante la inserción de los electrodos del implante coclear. En este artículo se presenta una revisión narrativa del uso y aplicación clínica de la electrococleografía en la evaluación de pacientes con implante coclear para predecir el desempeño auditivo y la percepción del habla. La literatura muestra que la electroco-cleografía es una técnica que se encuentra, plenamente, vigente para evaluar la función auditiva en pacientes usuarios de implantes cocleares. Si bien las respuestas cocleares han demostrado ser un buen predictor de los umbrales perceptuales auditivos y del habla en silencio en adultos, aún es una técnica que requiere más desarrollo para ser una herramienta clínica que permita predecir el habla en ruido y la función auditiva en niños y adultos mayores.

Electrocochleography is an electrophysiological technique developed in animal models more than 90 years ago. It is currently used in clinical practice in audiology and otoneurology, since it allows the evaluation of cochlear function, through the recording of the cochlear microphonic potentials, and the functionality of the auditory nerve by means of compound action potential recordings. Due to the advancement of cochlear implant technology, there is currently the possibility of real-time clinical measurements with intraoperative electrocochleography, so that residual hearing function can be monitored during the insertion of the cochlear implant electrodes. This article presents a narrative review of the use and clinical application of electrocochleography in the evaluation of patients with cochlear implants to predict auditory performance and speech perception. The literature shows that electrocochleography is a technique that is fully in force to assess hearing function in patients who use cochlear implants. Although cochlear responses have been shown to be a good predictor of auditory perceptual thresholds and speech in quiet in adults, it is still a technique that requires further development to become a clinical tool for predicting speech in noise and auditory function in children and older adults.

Implante coclear en otitis media crónica: Revisión de literatura

La otitis media crónica (OMC) activa y colesteatomatosa se consideraban una contraindicación para el uso de implante coclear (IC) en el pasado. Actualmente, se han propuesto múltiples opciones quirúrgicas para el IC, de acuerdo con las características clínicas del paciente y el tipo de patología otológica prexistente. La cirugía del IC se puede realizar en un tiempo o en etapas, siendo fundamental intervenir un oído seco y estable previo a la instalación definitiva del electrodo para reducir complicaciones y obtener resultados auditivos satisfactorios. El IC es un tratamiento seguro y eficaz en pacientes con OMC. Múltiples reportes internacionales han evidenciado baja tasa de complicaciones mayores y óptimos resultados auditivos funcionales en pacientes con hipoacusia y OMC.

Supurative and cholesteatomatous chronic otitis media (COM) were considered a contraindication to cochlear implant (CI) use in the past. Currently, multiple surgical options have been proposed for CI according to the clinical characteristics of the patient and the type of pre-existing otological pathology. Cochlear implant surgery can be performed in a single time or in stages, being essential to intervene a dry and stable ear prior to the definitive installation of the electrode to reduce complications and obtain satisfactory hearing results. CI is a safe and effective treatment in patients with COM. Multiple international reports have shown a low rate of major complications and optimal functional hearing results in patients with hearing loss and COM.

Evaluation of the Electrically-Evoked Stapedial Reflex Threshold in Pediatric Cochlear Implant Users with High-Frequency Probe Tones

Abstract Introduction Measurement of the electrically-evoked stapedial reflex threshold (ESRT) is an objective tool used to set the comfort levels in pediatric cochlear implant (PCI) users. The levels of ESRT have a strong correlation with comfort levels. However, the clinical utility of ESRT is limited because the ESRT response is not observed in all cochlear implant users. Objective To assess the effects of probe-tone frequency on ESRT and its relationship with the behavioral comfort levels in PCI users. Methods A total of 14 PCI users aged between 5 and 8 years participated in the study. The ESRT levels were measured using high-frequency probe tones (678 Hz and 1,000 Hz), and the default 226 Hz probe tone. The ESRT was measured with single-electrode stimulation across the three electrode locations (basal [E01]; middle [E11]; and apical [E22]). The ESRT levels measured with different probe tone frequencies were compared with the behavioral comfort levels. Results The mean ESRT levels using 1,000Hz and 678 Hz were lower than those measured using 226 Hz, but there was no main effect of probe-tone frequency (p > 0.05). A significantly high incidence of successful ESRT measurements occurred with higher-frequency probe tone (p < 0.039). Additionally, ESRT using higher probe tones significantly correlated with comfort levels. Conclusion The ESRT with higher probe tones was correlated with behavioral comfort levels and increased the success rate of the measurements. Higher-frequency probe tones may be useful whenever ESRT with 226 Hz is not measurable.

Cochlear implantation in an animal model documents cochlear damage at the tip of the implant / Implante coclear em um modelo animal documenta o dano coclear na extremidade do implante

Abstract Introduction: Electrocochleography has recently emerged as a diagnostic tool in cochlear implant surgery, purposing hearing preservation and optimal electrode positioning. Objective: In this experimental study, extra-cochlear potentials were obtained during cochlear implant surgery in guinea pigs. The aim was to determine electrophysiological changes indicating cochlear trauma after cochleostomy and after electrode implantation in different insertion depths. Methods: Normal-hearing guinea pigs (n = 14) were implanted uni- or bilaterally with a multichannel electrode. The extra-cochlear cochlear nerve action potentials were obtained in response to acoustic stimuli at specific frequencies before and after cochleostomy, and after introduction of the electrode bundle. After the electrophysiological experiments, the guinea pigs were euthanized and microtomography was performed, in order to determine the position of the electrode and to calculate of the depth of insertion. Based on the changes of amplitude and thresholds in relation to the stimulus frequency, the electrophysiological data and the position obtained by the microtomography reconstruction were compared. Results: Cochleostomy promoted a small electrophysiological impact, while electrode insertion caused changes in the amplitude of extra-cochlear electrophysiological potentials over a wide range of frequencies, especially in the deepest insertions. There was, however, preservation of the electrical response to low frequency stimuli in most cases, indicating a limited auditory impact in the intraoperative evaluation. The mean insertion depth of the apical electrodes was 5339.56 μm (±306.45 - 6 inserted contacts) and 4447.75 μm (±290.23 - 5 inserted contacts). Conclusions: The main electrophysiological changes observed during surgical procedures occurred during implantation of the electrode, especially the deepest insertions, whereas the cochleostomy disturbed the potentials to a lesser extent. While hearing loss was often observed apical to the cochlear implant, it was possible to preserve low frequencies after insertion. © 2020 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Resumo Introdução: A eletrococleografia surgiu recentemente como uma ferramenta diagnóstica na cirurgia de implante coclear, objetiva a preservação da audição e o posicionamento ideal dos eletrodos. Objetivo: Determinar as alterações eletrofisiológicas indicativas de trauma coclear após a cocleostomia e após o implante do eletrodo em diferentes profundidades de inserção. Método: Neste estudo experimental, potenciais extracocleares foram obtidos durante a cirurgia de implante coclear em cobaias. Cobaias com audição normal (n = 14) foram implantadas uni- ou bilateralmente com eletrodo multicanal. Os potenciais de ação do nervo coclear extracoclear foram obtidos em resposta a estímulos acústicos em frequências específicas antes e após a cocleostomia e após a introdução do feixe de eletrodos. Após os experimentos eletrofisiológicos, as cobaias foram submetidas à eutanásia e a microtomografia foi feita para determinar a posição do eletrodo e calcular a profundidade de inserção. Com base nas mudanças de amplitude e limiares em relação à frequência do estímulo, os dados eletrofisiológicos e a posição obtida na reconstrução microtomográfica foram comparados. Resultados: A cocleostomia promoveu um pequeno impacto eletrofisiológico, enquanto a inserção do eletrodo causou alterações na amplitude dos potenciais eletrofisiológicos extra-cocleares em uma ampla faixa de frequências, especialmente nas inserções mais profundas. Houve, entretanto, preservação da resposta elétrica aos estímulos de baixa frequência na maioria dos casos, indicou um impacto auditivo limitado na avaliação intraoperatória. A profundidade média de inserção dos eletrodos apicais foi 5339,56 μm (± 306,45 - 6 contatos inseridos) e 4447,75 μm (± 290,23 - 5 contatos inseridos). Conclusão: As principais alterações eletrofisiológicas observadas durante os procedimentos cirúrgicos ocorreram durante o implante do eletrodo, especialmente nas inserções mais profundas, enquanto a cocleostomia alterou os potenciais em menor grau. Embora a perda auditiva seja frequentemente observada em posição apical ao implante coclear, foi possível preservar as baixas frequências após a inserção.

Does universal newborn hearing screening impact the timing of deafness treatment?

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.

Current criteria for selecting cochlear implant in deaf patients: areview

Cochlear implantation is indicated in patients with severe to profound hearing loss that cannot be adequately treated by other auditory rehabilitation measures.The definitive indication of cochlear implantation is made on the basis of an extensive interdisciplinary clinical,audiological,radiological, and psychological diagnostic work-up.There are numerous changes are happening in cochlear implant candidacy.These have been associated with concomitant changes in surgical techniques,which enhanced the utility and safety of cochlear implantation.Currently, cochlear implants are approved for individuals with severe to profound unilateral hearing loss rather than previously needed for bilateral profound hearing loss.Studies have begun using the short electrode arrays for shallow insertion in patients with low-frequency residual hearing loss.The advancement in designs of thecochlear implant along with improvements in surgical techniques reduce the complications and result in the safety and efficacy of the cochlear implant which further encourages the use of these devices.This review article aims to discuss the new concepts in the candidacy of the cochlear implant,cochlear implant in younger children and hearing preservation,a cochlear implant for unilateral deafness,bilateral cochlear implant, and cochlear implant with neural plasticity and selection of patients for the cochlear implant.

Sheep as a large animal model for cochlear implantation / Uso de ovelhas como um modelo animal de grande porte para implante coclear

Abstract Introduction In surgical training, large animal models are more suitable as their anatomy is more similar to humans. In otology, there have been relatively few studies about large animal models for surgical training. Objective In this study, we aimed to do a neuroradiologic evaluation and surgical insertion of a cochlear implant electrode array on a sheep head model. Methods Twenty cadaveric sheep heads were studied. A computed tomography scan and neuroradiologic evaluation was performed on each head, obtaining measurements of the inner ear for each sheep. Sheep measurements were compared to those from temporal bone computed tomography scans from 20 female humans. Surgical procedures were first trained with 13 of the sheep temporal bones, after which cochlear implantation was performed on the remaining 7 temporal bones. The position of the inserted electrode array insertion was confirmed by computed tomography scan after the procedure. Results Neuroradiologic evaluation showed that, relative to the 20 female humans, the mean ratio for sheep was 0.60 for volume of cochlea, 0.70 for height of cochlea, 0.73 for length of cochlea; ratios for other metrics were >0.80. For the surgical training, the round window was found in all 20 sheep temporal bones. Computed tomography scans confirmed that electrode insertions were fully complete; the mean value of electrode array insertion was 18.3 mm. Conclusion The neuroradiologic and surgical training data suggest that the sheep is a realistic animal model to train cochlear implant surgery and collection of perilymph samples, but less so for surgical training of mastoidectomy due to pneumatization of the mastoid.

Resumo Introdução No treinamento cirúrgico, os modelos animais de grande porte são mais adequados, pois sua anatomia é mais semelhante à humana. Em otologia, existem relativamente poucos estudos com modelo animal de grande porte para treinamento cirúrgico. Objetivo Fazer a avaliação neurorradiológica e a inserção cirúrgica de um eletrodo de implante coclear em um modelo de ovelha. Método Vinte cabeças de cadáveres de ovelhas foram estudadas. Foram feitas tomografia computadorizada e avaliação neurorradiológica de cada cabeça, obtiveram‐se medidas da orelha interna de cada ovelha. As medidas das ovelhas foram comparadas às de tomografias computadorizadas do osso temporal de 20 mulheres. Os procedimentos cirúrgicos foram inicialmente treinados com 13 dos ossos temporais de ovelhas, após o qual o implante coclear foi feito nos 7 ossos temporais restantes. A posição de inserção do arranjo de eletrodos foi confirmada por tomografia computadorizada após o procedimento. Resultados A avaliação neurorradiológica mostrou que, em comparação às 20 mulheres, a proporção média para as ovelhas foi de 0,60 para o volume da cóclea, 0,70 para a altura da cóclea, 0,73 para o comprimento da cóclea; as proporções para as outras medidas foram > 0,80. Em relação ao treinamento cirúrgico, a janela redonda foi encontrada em todos os 20 ossos temporais de ovelhas. A tomografia computadorizada confirmou que as inserções dos eletrodos foram totalmente completas; o valor médio da inserção do arranjo de eletrodos foi de 18,3 mm. Conclusão Os dados do treinamento neurorradiológico e cirúrgico sugerem que a ovelha é um modelo animal realista para o treinamento da cirurgia de implante coclear e coleta de amostras da perilinfa, mas não tão realista para o treinamento cirúrgico de mastoidectomia devido à pneumatização da mastoide.

Perkembangan Bahasa dan Pertuturan Kanak-Kanak Melayu Pengguna Implan Koklea di bawah Program Implan Koklea Kebangsaan, Kementerian Kesihatan Malaysia (Speech and Language Development of Malay Children with Cochlear Implants under the National Cochlear Implant Program, Ministry of Health Malaysia) / Jurnal Sains Kesihatan Malaysia

@#Speech and language skills are among the crucial components in determining cochlear implant habilitation outcomes. The purpose of this study was to investigate speech and language skills of Malay cochlear implant children using a developmental scale questionnaire and to identify the demographic factors that contribute to their performance. This study involved 26 children recruited from the National Cochlear Implant Program under the Malaysian Ministry of Health with chronological ages between 33 to 99 months (mean=72, SD=18.9), implant ages between 18 to 71 months (mean=40, SD=13.5) and hearing ages between 13 to 48 months (mean=30, SD=10.5). The instrument used was The Integrated Scale of Development-Malay version 2 (ISD-Mv2). The questionnaires were given to the parents or caregivers followed with by a phone call interview later. Results from the study showed that only 9 subjects (35%) were able score on the ISD-Mv2 equally or higher than their hearing age. From the six components in the ISD-Mv2, cognitive was scored the highest with 96.79% meanwhile expressive language was the lowest with 76.21%. Pearson correlation test revealed strong positive correlation between audition-receptive language (r=0.554, p<0.05) and cognitive–social communication/ pragmatic (r= 0.625, p<0.05). Speech and language performance of children with demographic factors did not show significant differences. The findings suggests that majority of the Malay cochlear implant children demonstrated delayed speech and language performance as compared to normal hearing children.

A Scoping Review of Assessment Tools and Factors Influencing Spoken Language Development Among Pediatric Cochlear Implant Users (Kajian Skop mengenai Alat dan Faktor Penilaian yang Mempengaruhi Perkembangan Bahasa Pertuturan dalam Kalangan Pengguna Implan Koklea Pediatrik) / Jurnal Sains Kesihatan Malaysia

@#The spoken language development strongly depends on the normally functioning auditory system. For children with severe or profound hearing loss, cochlear implant has become the best solution in improving and promoting spoken language, quality of life, self-esteem and social well-being. Standardized self-report questionnaires are considered as the most widely used and low-cost approach to measure spoken language development among children. We aimed to provide an overview of the questionnaires available for assessing the spoken language development among children with cochlear implant. In addition, factors that may influence the development of good spoken language were also reviewed. A literature search from January 2010 to December 2020 making use of the Science Direct and PubMed databases was conducted. Medical Subject Headings (MeSH) and other key words for the search were (communication OR language) AND cochlear implant AND (children OR pediatric) AND (questionnaire OR survey). Research articles that were identified in the database using the keywords were refined by year. Only original articles were selected. Articles that quoted all the selected key words in the title and abstract; and written in English with full text were included in the review. Twelve instruments were utilized in the methodology of the 10 articles. Only one instrument was specific for spoken language assessment of children with cochlear implant. The age at which a child received an implant, good rehabilitation program and active involvement of parents was found to influence development of good spoken language skills among the cochlear implanted children. Cochlear implants provide deaf children with the opportunity to develop spoken language skills. Longer use of a cochlear implant dramatically affects the amount of spoken language. Rather, it was cochlear implantation at a younger age that served to assists spoken language competence.
