ABSTRACT

Resumen La fisiopatología del tinnitus crónico no pulsátil es poco clara, pero se reconoce un componente psicológico relevante, por tanto, existen distintas aproximaciones psicoterapéuticas que han sido estudiadas. La terapia cognitivo conductual es la que cuenta con mayor evidencia. Ella contempla la reestructuración de las cogniciones disfuncionales que favorecen la presencia del tinnitus. Se ha verificado su eficacia en los niveles de distrés, calidad de vida, severidad, sintomatología depresiva e insomnio asociados. La desensibilización y reprocesamiento por movimientos oculares recoge algunos presupuestos de la terapia cognitivo conductual, pero considera técnicas como la estimulación bilateral. Sus resultados en patologías crónicas somáticas han sugerido la aplicación en tinnitus, corroborando su eficacia en calidad de vida, distrés y sintomatología depresiva. Dos psicoterapias basadas en mindfulness aplicadas en tinnitus son la reducción del estrés basado en el mindfulness y la terapia cognitiva basada en mindfulness. La primera ha demostrado eficacia en la calidad de vida y en la disminución y el refuerzo de cogniciones negativas y positivas, respectivamente. La segunda, es eficaz en la severidad, intensidad, distrés, ansiedad, depresión y discapacidad asociadas a tinnitus. Finalmente, la terapia de aceptación y compromiso promueve la aceptación como componente central del tratamiento de condiciones crónicas, considerando el control que ejerce el contexto sobre la vivencia de estas condiciones y el compromiso terapéutico. Esta terapia es eficaz en calidad de vida. Se promueve la investigación en aproximaciones psicoterapéuticas para el tinnitus, lo que posibilitará la aplicación de terapias más específicas y la clarificación de su fisiopatología.


Abstract The pathophysiology of non-pulsatile chronic tinnitus is unclear, but it is recognized a relevant psychological component. In this sense, different psychotherapeutic approaches have been studied. Cognitive behavioral therapy is the psychotherapy with the most evidence. It considers the restructuring of dysfunctional cognitions that favor the presence of tinnitus. Its efficacy has been verified on distress, quality of life, severity, associated depressive symptoms and insomnia. Eye movement desensitization and reprocessing includes some conceptions of cognitive behavioral therapy and considers techniques such as bilateral stimulation. Its results in chronic somatic pathologies have suggested its application in tinnitus, corroborating its efficacy in quality of life, distress, and depressive symptoms. Two mindfulness-based psychotherapies applied in tinnitus are mindfulness-based stress reduction and mindfulness-based cognitive therapy. The first has shown efficacy on quality of life and reduction and reinforcement of negative and positive cognitions, respectively. The second is effective on severity, loudness, distress, anxiety, depression and disability associated with tinnitus. Finally, acceptance and commitment therapy promote acceptance as a central component of the treatment of chronic conditions, considering the control exerted by the context over the experience of these conditions and the therapeutic commitment. This therapy is effective on quality of life. We foster the research on psychotherapeutic approaches to tinnitus, which will make it possible the application of more specific interventions and, at the same time, elucidate its pathophysiology.

ABSTRACT

Resumen El acúfeno es un síntoma relativamente frecuente en una consulta de otorrinolaringología. Se han descrito interacciones en las células ciliadas externas o internas, desequilibrios en el balance de las fibras aferentes y fenómenos de reorganización cortical tras lesiones periféricas que están involucrados en un 90%-95% de las causas del acúfeno. El restante 5%-10% está constituido por un tipo de acúfenos llamados objetivos, que no comparten estos mecanismos fisiopatológicos, sino que se originan en alguna estructura del organismo generalmente ajena a la vía auditiva y estimulan el aparato auditivo igual que lo haría un sonido del exterior. Presentamos el caso de un varón de 52 años remitido al Servicio de Otorrinolaringología de nuestro hospital por acúfeno pulsátil de meses de evolución, sin asociar hipoacusia, ni vértigo, ni otra sintomatología.


Abstract Tinnitus is a relatively frequent symptom in an otolaryngology consultation. Interactions in external or internal hair cells, imbalances in the afferent fiber balance and cortical reorganization phenomena after peripheral injuries have been described in 90%-95% of the causes of tinnitus. The remaining 5%-10% is comprised of a type of tinnitus called objective, which do not share these pathophysiological mechanisms, but originate from some structure of the body generally external to the auditory pathway and stimulate the auditory apparatus just as a sound from the exterior. We present the case of a 52-year-old man referred to the Otolaryngology service at our hospital for pulsatile tinnitus of months of evolution, with no hearing loss, vertigo, or other symptoms associated.

ABSTRACT

Abstract Introduction: Tinnitus is a central auditory disorder in which different processing systems are involved as a network. One of these networks is memory. Previous studies have demonstrated some deficits in various types of memory in chronic tinnitus. Objectives: The main purpose of the present study was to investigate the semantic memory, which is not yet investigated in the tinnitus population. Methods: In this case-control study, 15 subjects with chronic tinnitus and 16 matched healthy controls were included. 40 semantically related and 40 semantically unrelated word pairs were presented to the participants in a counter-balanced fashion. They were asked to make decision about their semantic relatedness. Then the participants' reaction times and the accuracy of responses were calculated. Results: Mean of reaction times were significantly longer in the tinnitus group (M = 1034 ms, SD = 0.31) compared to the control group (Mean = 1016 ms, SD = 0.13), p < 0.05. However, no significant difference was found for the mean percentage of correct responses between the two groups. Conclusion: The current study provided behavioral evidence that chronic tinnitus can affect the semantic memory. Such behavioral outcomes may provide new insights into more research activities in the field of electrophysiology and neuroimaging in the tinnitus population.


Resumo Introdução: O zumbido é um distúrbio auditivo central, no qual diferentes sistemas de processamento estão envolvidos como em uma rede. Uma dessas redes é a memória. Estudos anteriores demonstraram alguns déficits em vários tipos de memória no zumbido crônico. Objetivos: Investigar a memória semântica, que ainda não foi investigada na população com zumbido. Método: Neste estudo de caso-controle, 15 indivíduos com zumbido crônico e 16 controles saudáveis pareados foram incluídos; 40 pares de palavras semanticamente relacionados e 40 semanticamente não relacionados foram apresentados aos participantes de forma contrabalançada. Eles foram instruídos a tomar decisões sobre sua relação semântica. Em seguida, os tempos de reação dos participantes e a precisão das respostas foram calculados. Resultados: A média dos tempos de reação foi significativamente maior no grupo com zumbido (M = 1,034 ms, DP = 0,31) em comparação ao grupo controle (média = 1,016 ms, DP = 0,13), p< 0,05. Entretanto, nenhuma diferença significante foi encontrada para a porcentagem média de respostas corretas entre os dois grupos. Conclusão: O presente estudo forneceu evidências comportamentais de que o zumbido crônico pode afetar a memória semântica. Tais resultados comportamentais podem levar a novas percepções em mais atividades de pesquisa no campo da eletrofisiologia e neuroimagem na população com zumbido.

ABSTRACT

Abstract Introduction Tinnitus is present in a large part of chronic health complaints, and it is considered a public health problem injurious to the individual's quality of life. Considering the increase of the world population associated with an increase of life expectancy, tinnitus remains a cause for medical concern, since during aging the occurrence of auditory impairments due to the deterioration of the peripheral auditory structures and central impairs the quality of life. Objective The aim of the present study was to analyze the applicability of real ear measurements for audiological intervention of tinnitus through specific evaluation, selection, verification and validation of the hearing aids combined with the sound generator. Methods Forty individuals of both genders with hearing loss and tinnitus complaints were deemed eligible to compose the sample. They were enrolled according to clinical symptoms and submitted to the following procedures: anamnesis and previous complaint history, high frequency audiometry, immittanciometry and acuphenometry with the research of psychoacoustic thresholds of pitch, loudness and minimum masking threshold, sound generator, in addition to the application of the Tinnitus Handicap Inventory and Visual Analog Scale tools. The entire sample was adapted with Siemens hearing aids and a sound generator, participated in a counseling session with support of digital material and evaluated in two situations: Initial Assessment (before the hearing aids and sound generator adaptation) and Final Assessment (6 months, after adaptation). The statistical analyzes were descriptive and inferential, adopted a significance level of 5% and the T-Paired Test and the Spearman Correlation test were performed. Results The results showed that there was a benefit with the use of hearing aids combined with a sound generator from the statistically significant values and strong correlations between the sound generator verification data regarding acuphenometry and the nuisance/severity questionnaires. Regarding the verification of the sound generator, it is important to highlight that the entire sample selected the effective acoustic stimulation based on the comfort levels, which was proved in the present study to be a sufficient intensity for positive prognosis, whereas the users' noises were found below the psychoacoustic thresholds of acuphenometry. Conclusion The present study concluded that the audiological intervention with any level of sound stimulus is enough to obtain a positive prognosis in the medium term. Data that specifies that the verification of sound generator was effective at the real ear measurements are important in the evaluation and intervention of the complaint. In addition, it points out that the greater the tinnitus perception, the greater its severity, and the greater the nuisance, the higher the psychoacoustics thresholds of frequency and the minimum threshold of masking.


Resumo Introdução O zumbido está presente em grande parte das queixas crônicas de saúde, é considerado um problema de saúde pública, prejudicial à qualidade de vida do indivíduo. Considerando o aumento da população mundial associado ao aumento da expectativa de vida, a tendência é que o zumbido permaneça como um motivo de preocupação, uma vez que com a idade a ocorrência de prejuízos auditivos decorrentes da deterioração das estruturas auditivas periféricas e centrais ocasiona grande impacto negativo na qualidade de vida. Objetivo Analisar a aplicabilidade das medidas da orelha real para a intervenção audiológica do zumbido através de avaliação específica, seleção, verificação e validação do aparelho de amplificação sonora individual combinada ao gerador de som. Método Quarenta indivíduos de ambos os sexos com perda auditiva e queixa de zumbido foram considerados elegíveis para compor a amostra. Eles foram atendidos conforme a demanda clínica e submetidos aos seguintes procedimentos: anamnese e história pregressa da queixa, audiometria de alta frequência, imitanciometria e acufenometria com pesquisa dos limiares psicoacústicos de pitch, loudness e limiar mínimo de mascaramento, gerador de som, além da aplicação das ferramentas tinnitus handicap inventory e escala visual analógica. Toda a amostra recebeu aparelho de amplificação sonora individual e gerador de som, ambos da marca Siemens, participaram de uma sessão de aconselhamento com apoio de material digital e foram avaliados em duas situações: Avaliação inicial (antes da adaptação dos aparelhos de amplificação sonora individual e gerador de som) e Avaliação final (6 meses após a adaptação). As análises estatísticas foram descritivas e inferenciais, adotou-se um nível de significância de 5% com a realização do teste t pareado e o teste de correlação de Spearman. Resultados Os resultados mostraram que houve benefício com o uso de aparelho de amplificação sonora individual combinado ao gerador de som com base nos valores estatisticamente significantes e fortes correlações entre os dados da verificação do gerador de som em relação à acufenometria e os questionários de incômodo/gravidade. Em relação à verificação do gerador de som, é importante destacar que toda a amostra selecionou a estimulação acústica efetiva baseada nos níveis de conforto e no presente estudo demonstraram ser de intensidade suficiente para o prognóstico positivo, enquanto que os ruídos dos usuários estavam abaixo dos limiares psicoacústicos da acufenometria. Conclusão A intervenção audiológica com qualquer nível de estímulo sonoro é suficiente para obter um prognóstico positivo em médio prazo. Os dados que demonstram que a verificação do gerador de som foi efetiva nas medidas da orelha real são importantes na avaliação e intervenção da queixa. Além disso, mostram que quanto maior a percepção do zumbido, maior a sua gravidade; e quanto maior o incômodo, maiores os limiares de frequência psicoacústica e o limiar mínimo de mascaramento.

ABSTRACT

Abstract Introduction Tinnitus is sound perception in the absence of a sound source. Changes in parameters of latency and amplitude on the auditory event related potentials or long latency potentials waves have been cited in tinnitus patients when compared to a control group. Objective To perform an assessment of scientific evidence that verifies the possibility of alterations in latency or amplitude of the waves of event related potentials in individuals with tinnitus. Methods By using SciELO, Lilacs, ISI Web and PubMed, scientific databases, a review was performed. Articles published in English, Portuguese, French and Spanish that correlated tinnitus with changes in event related potentials were included in this review. Results Twelve articles were located, however only eight fulfilled the criteria for inclusion. Conclusion The sample of selected studies demonstrate that the long latency auditory evoked potentials related to events between the control and tinnitus patients showed some changes in latency and or amplitude in tinnitus patients. There are changes in event-related potentials when comparing patients with tinnitus and the control group. These changes take place considering the severity of tinnitus, tinnitus site of lesion, and capacity for changes after interventions. The event related potentials can help to determine the neurotransmitter involved in tinnitus generation and evaluate tinnitus treatments.


Resumo Introdução O zumbido é a percepção de um som na ausência de uma fonte sonora. Mudanças nos parâmetros de latência e amplitude nas ondas dos potenciais evocados auditivos relacionados a eventos ou potenciais de longa latência foram citadas em pacientes com zumbido quando comparados a um grupo controle. Objetivo Realizar uma avaliação de evidências científicas que verifiquem a possibilidade de alterações na latência ou amplitude das ondas de potenciais evocados auditivos relacionados a eventos em indivíduos com zumbido. Método Foi feita uma revisão a partir dos bancos de dados científicos SciELO, Lilacs, ISI Web e PubMed. Artigos publicados em inglês, português, francês e espanhol que correlacionavam zumbido com alterações nos potenciais evocados auditivos relacionados a eventos foram incluídos. Resultados Foram localizados 12 artigos, porém apenas oito preencheram os critérios de inclusão. Conclusão A amostra de estudos selecionados demonstra que os potenciais evocados auditivos de longa latência relacionados a eventos entre os pacientes-controle e com zumbido apresentaram algumas alterações na latência e/ou amplitude nos pacientes com zumbido. Há mudanças nos potenciais relacionados a eventos ao comparar pacientes com zumbido e o grupo controle. Essas alterações consideram a gravidade do zumbido, o local da lesão do zumbido e a capacidade de alterações após as intervenções. Os potenciais evocados auditivos relacionados a eventos podem ajudar a determinar o neurotransmissor envolvido na geração do zumbido e avaliar os tratamentos para o zumbido.

ABSTRACT

Abstract Introduction: Tinnitus is a subjective auditory symptom usually associated with a sound, even in the absence of external sound sources. Its diagnosis is complex, and some of the forms of measurement alone or in combination, include self-assessment questionnaires, such as the tinnitus handicap inventory, the visual analog scale and/or pitch and loudness matching. Objective: To analyze the correlation among three tinnitus measurement methods: tinnitus handicap inventory, visual analog scale and pitch and loudness matching. Methods: The study consisted of 148 patients complaining of chronic tinnitus. An otorhinolaryngological evaluation, anamnesis directed to tinnitus, audiometry (pure tone and speech), imitanciometry, tinnitus handicap inventory, visual analog scale, and pitch and loudness matching were performed. The study was registered in the Ethics Committee of the Institution with no. 0129/12. Results: Regarding the frequency of tinnitus handicap inventory responses, a higher occurrence of the mild degree was observed. An average of 6 points was observed on the visual analog scale. The mean loudness matching in the right ear was 20 dBNS, and in the left ear was 17 dBNS. As for the type of stimulus, the most found was continuous pure tone. The frequency of the pitch sensation was 6000 Hz in the largest number of cases. Regarding the measures of tinnitus handicap inventory and the visual analogical scale, a significant correlation was observed, and as one value increases the other also increases. Pitch and loudness matching and the visual analogical scale results are also significant. Conclusion: There was a significant correlation between the values measured by the tinnitus handicap inventory, visual analogical scale (annoyance) and loudness matching in the evaluation of tinnitus. The selection of any one of the three evaluative methods for tinnitus investigation provides different dimensions of the tinnitus and complements the others.


Resumo Introdução: O zumbido é um sintoma auditivo de natureza subjetivo, normalmente associado a um som, mesmo na ausência de fontes sonoras externas. Apresenta diagnóstico complexo. Uma das formas de mensuração é o uso, isolado ou em conjunto, de questionários de autoavaliação, como o Tinnitus Handicap Inventory, a escala visual analógica e o exame de acufenometria. Objetivo: Analisar a correlação entre os métodos de mensuração do zumbido: Tinnitus Handicap Inventory, escala visual analógica e acufenometria. Método: Participaram do estudo 148 pacientes com queixa de zumbido crônico. Realizou-se avaliação otorrinolaringológica, anamnese direcionada ao zumbido, audiometria (tonal e vocal), imitanciometria, Tinnitus Handicap Inventory, escala visual analógica e acufenometria. O estudo foi registrado no comitê de ética da instituição, com nº 0129/12. Resultados: Em relação à frequência das respostas do Tinnitus Handicap Inventory, foi observada maior ocorrência do grau leve. Observou-se uma média de 6 pontos na escala visual analógica. A média da sensação de intensidade medida na acufenometria na orelha direita foi de 20 dBNS e na orelha esquerda foi de 17 dBNS. Quanto ao tipo de estímulo, o mais encontrado foi o tom puro contínuo. A sensação de frequência, no maior número de casos, foi de 6.000 Hz Entre as medidas do Tinnitus Handicap Inventory e da escala visual analógica, observou-se correlação significante. À medida que um valor aumenta o outro também aumenta. Os resultados da acufenometria e da escala visual analógica também apresentam significância. Conclusão: Houve correlação significante entre os valores medidos pelo Tinnitus Handicap Inventory, escala visual analógica (incômodo) e acufenometria (loudness) na avaliação do zumbido. A escolha de um dos três métodos avaliativos para pesquisa do zumbido fornece dimensões diferentes do zumbido e se complementam.

ABSTRACT

RESUMEN El tinnitus es un síntoma caracterizado por la percepción de un sonido en ausencia de un estímulo externo. Si bien su fisiopatología puede involucrar una alteración a nivel del funcionamiento del oído interno, la percepción de éste y el grado de molestias asociadas dependen de modificaciones de redes cerebrales cognitivas y emocionales. En la presente revisión, se abordan los cambios que existen a nivel coclear, de tronco encefálico, tálamo y la extensa red cerebral que dan cuenta del tinnitus, discutiendo como esta nueva conceptualización tiene importantes implicancias clínicas, permitiendo una mejor comprensión de los síntomas asociados al tinnitus, sus comorbilidades, y el desarrollo de nuevas estrategias terapéuticas.


ABSTRACT Tinnitus is a symptom characterized by the perception of a sound without an external stimulus. Although the pathophysiology of tinnitus initially involves an alteration of the inner ear function, the perception of it and the degree of distress associated with it depends on changes in cognitive and emotional brain networks. In this article, we review the changes that exist at the cochlea, brainstem, thalamus and a widespread cerebral networks that account for tinnitus, discussing how this new conceptualization has significant clinical implications and allows a better understanding of the symptoms associated with tinnitus, its co-morbidities, and how this view has allowed the development of new therapies.

ABSTRACT

Abstract Introduction: Due to the subjectivity of the tinnitus diagnosis and its diverse etiologies, establishing an effective treatment is complex. In this context, transcranial direct current stimulation, a noninvasive option, is available for most patients and has shown good results in the treatment of other symptoms such as chronic pain. Objective: To evaluate the therapeutic response of tinnitus to transcranial direct current stimulation. Methods: A systematic review of the literature was performed using the following descriptors: tinnitus, transcranial direct current stimulation and randomized clinical trial. The research was carried out in the MEDLINE/PUBMED, Lilacs, and Scielo databases. The inclusion criteria were: patients over 18 years of age with no associated comorbidities, who had a diagnosis established by a specialist or through the application of previously validated scales and criteria applied by a non-specialist physician. Results: A total of 4165 studies were found, and a total of six were selected after the inclusion criteria were applied, obtaining a sample of 602 patients. Based on the defined criteria, there was a positive response to transcranial direct current stimulation in 14.86% of the participants. Conclusion: Based on literature studied, there is no therapeutic response of tinnitus to transcranial direct current stimulation.


Resumo Introdução: Devido à subjetividade do diagnóstico do zumbido e a suas diversas etiologias, o estabelecimento de um tratamento eficaz é complexo. Nesse contexto surge a transcranial direct current stimulation, uma opção não invasiva, acessível para grande parte dos pacientes, e que tem apresentado bons resultados no tratamento de outros sintomas como dor crônica. Objetivo: Avaliar a resposta terapêutica do zumbido ao transcranial direct current stimulation. Método: Foi realizada uma revisão sistemática da literatura, por meio dos seguintes descritores: zumbido, transcranial direct current stimulation e ensaio clínico randomizado.

ABSTRACT

Resumen INTRODUCCIÓN: Se han propuesto múltiples tratamientos para el manejo del tinnitus, sin embargo, ninguno de ellos ha logrado establecerse como claramente efectivo. Dentro de las alternativas se ha planteado la utilización de Ginkgo biloba. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos tres revisiones sistemáticas que en conjunto incluyeron cuatro estudios primarios, todos correspondientes a ensayos aleatorizados. Concluimos que el uso de Ginkgo Biloba probablemente no disminuye la severidad del tinnitus. Además, no disminuye la intensidad del tinnitus ni mejora la calidad de vida de los pacientes.


Abstract INTRODUCTION: Multiple interventions have been postulated for the treatment of tinnitus, but none has been established as clearly effective. Ginkgo biloba has been proposed among the alternatives. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified three systematic reviews including four primary studies, all corresponding to randomized trials. We concluded the use of Ginkgo biloba probably does not decrease the severity of tinnitus. In addition, it does not reduce the intensity of tinnitus or improve the quality of life of patients.

ABSTRACT

Introduction Tinnitus is an abnormal perception of sound in the absence of an external stimulus. Chronic tinnitus usually has a high impact in many aspects of patients' lives, such as emotional stress, sleep disturbance, concentration difficulties, and so on. These strong reactions are usually attributed to central nervous system involvement. Neuroimaging has revealed the implication of brain structures in the auditory system. Objective This systematic review points out neuroimaging studies that contribute to identifying the structures involved in the pathophysiological mechanism of generation and persistence of various forms of tinnitus. Data Synthesis Functional imaging research reveals that tinnitus perception is associated with the involvement of the nonauditory brain areas, including the front parietal area; the limbic system, which consists of the anterior cingulate cortex, anterior insula, and amygdala; and the hippocampal and parahippocampal area. Conclusion The neuroimaging research confirms the involvement of the mechanisms of memory and cognition in the persistence of perception, anxiety, distress, and suffering associated with tinnitus.

ABSTRACT

INTRODUCTION: Although tinnitus is an increasingly common symptom, few studies have assessed its prevalence or incidence among adolescents. PURPOSE: To assess whether the presence of tinnitus in adolescents is associated with minimal hearing damage, evaluated through high-frequency audiometry (HFA), otoacoustic emission (OAE), and loudness discomfort level (LDL). METHODS: The sample comprised 168 adolescents of a private school (61.3% boys; mean age 14.1 years old; standard deviation=2). All of them completed a questionnaire about tinnitus and hypersensitivity to sounds (sound intolerance), and then underwent otoscopy, pure-tone audiometry, HFA, LDL, transient and distortion product otoacoustic emissions (TOAE and DPOAE), and tinnitus pitch/loudness matching (the latter only in those with tinnitus). Participants were later divided into three groups: with no tinnitus (n=73, 43.4%), with sporadic tinnitus (n=47, 28%), and with constant tinnitus (n=48, 28.6%). RESULTS: No significant difference was observed between the groups regarding audiometry thresholds in frequencies from 0.25 to 16 kHz, or TOAE and DPOAE. However, the LDL in adolescents with constant tinnitus was significantly lower than that in other groups, suggesting hypersensitivity to sounds. CONCLUSION: There was no evidence of minimal hearing damage in the audiometry and OAE. Nonetheless, the decreased LDL in adolescents with constant tinnitus suggests that their auditory system is more sensitive. Therefore, this may be the first sign of vulnerability to sounds. Future medium- to long-term monitoring of these students may show whether they will begin a process of functional impairment, altering hearing thresholds, and OAE. .


Embora o zumbido seja um sintoma cada vez mais comum, poucos estudos avaliaram sua prevalência ou incidência entre adolescentes. OBJETIVO: Avaliar se a presença de zumbido em adolescentes está associada a lesões auditivas mínimas, avaliadas por audiometria de altas frequências (AAF), emissões otoacústicas (EOA) e limiar de desconforto a sons (LDL). MÉTODOS: Participaram da amostra 168 alunos adolescentes de uma escola particular, sendo 61,3% do gênero masculino e com média de idade de 14,1 anos (desvio padrão=2). Todos responderam a um questionário sobre zumbido e hipersensibilidade auditiva (intolerância a sons) e foram submetidos à otoscopia, audiometria tonal convencional e de frequências acima de 8.000 Hz, LDL, EOA transientes (EOAT) e produto de distorção (EOAPD) e acufenometria (esta apenas naqueles com zumbido). Em seguida, foram divididos em três grupos: Sem Zumbido (n=73; 43,4%), Zumbido Esporádico (n=47; 28%) e Zumbido Constante (n=48; 28,6%). RESULTADOS: Não houve diferença significativa entre os grupos em relação aos limiares da audiometria nas frequências de 250 a 16.000 Hz, nem nas EOAT ou EOAPD. Entretanto, o LDL dos adolescentes com zumbido constante foi significativamente menor do que o dos demais grupos, sugerindo hipersensibilidade auditiva. CONCLUSÃO: Não houve evidência de alterações auditivas mínimas na audiometria e EOA. Entretanto, a diminuição do LDL em jovens com zumbido constante sugere que suas cócleas sejam mais sensíveis. Portanto, esse pode ser o primeiro sinal de vulnerabilidade a sons, mas o acompanhamento desses adolescentes a médio prazo poderá demonstrar se tais regiões entrarão em processo de comprometimento funcional, alterando os limiares audiométricos e as EOA. .

ABSTRACT

OBJECTIVES: We evaluated the central auditory pathways in workers with noise-induced tinnitus with normal hearing thresholds, compared the auditory brainstem response results in groups with and without tinnitus and correlated the tinnitus location to the auditory brainstem response findings in individuals with a history of occupational noise exposure. METHOD: Sixty individuals participated in the study and the following procedures were performed: anamnesis, immittance measures, pure-tone air conduction thresholds at all frequencies between 0.25-8 kHz and auditory brainstem response. RESULTS: The mean auditory brainstem response latencies were lower in the Control group than in the Tinnitus group, but no significant differences between the groups were observed. Qualitative analysis showed more alterations in the lower brainstem in the Tinnitus group. The strongest relationship between tinnitus location and auditory brainstem response alterations was detected in individuals with bilateral tinnitus and bilateral auditory brainstem response alterations compared with patients with unilateral alterations. CONCLUSION: Our findings suggest the occurrence of a possible dysfunction in the central auditory nervous system (brainstem) in individuals with noise-induced tinnitus and a normal hearing threshold. .

ABSTRACT

OBJECTIVE: The goal of this study was to observe spontaneous cortical activity and cortical activity modulated by tinnitus-matched sound in tinnitus patients and healthy subjects with no otoneurologic symptoms. METHOD: Data were prospectively collected from 50 tinnitus patients and 25 healthy subjects. Cortical activity was recorded in all subjects with eyes closed and open and during photostimulation, hyperventilation and acoustic stimulation using 19-channel quantitative electroencephalography. The sound applied in the tinnitus patients was individually matched with the ability to mask or equal the tinnitus. The maximal and mean amplitude of the delta, theta, alpha and beta waves and the type and amount of the pathologic EEG patterns were noted during each recording. Differences in cortical localization and the influence of sound stimuli on spontaneous cortical activity were evaluated between the groups. RESULTS: The tinnitus group exhibited decreased delta activity and increased alpha and beta activity. Hyperventilation increased the intensity of the differences. The tinnitus patients had more sharp-slow waves and increased slow wave amplitude. Sound stimuli modified the EEG recordings; the delta and beta wave amplitudes were increased, whereas the alpha-1 wave amplitude was decreased. Acoustic stimulation only slightly affected the temporal region. CONCLUSION: Cortical activity in the tinnitus patients clearly differed from that in healthy subjects, i.e., tinnitus is not a “phantom” sign. The changes in cortical activity included decreased delta wave amplitudes, increased alpha-1, beta-1 and beta-h wave amplitudes and pathologic patterns. Cortical activity modifications occurred predominantly in the temporal region. Acoustic stimulation affected spontaneous cortical activity only in tinnitus patients, and although the applied sound was individually matched, the pathologic changes were only slightly improved. .

ABSTRACT

Dor crônica nas imediações do ouvido pode influenciar o zumbido. OBJETIVO: Investigar a eficácia da desativação de pontos-gatilho miofasciais na melhora do zumbido. MÉTODO: Ensaio clínico randomizado com 71 pacientes com zumbido e síndrome dolorosa miofascial. O Grupo Experimental (n = 37) foi submetido a 10 sessões de desativação dos pontos-gatilho miofasciais e o Grupo Controle (n = 34), a 10 sessões de desativação placebo. RESULTADOS: O tratamento do Grupo Experimental foi eficaz para o controle do zumbido (p < 0,001). Houve associação entre as melhoras de dor e zumbido (p = 0,013) e entre os lados da orelha com pior zumbido e do corpo com mais dor (p < 0,001). A presença de modulação (aumento ou diminuição) temporária do zumbido durante a palpação inicial dos pontos foi frequente em ambos os grupos, mas a diminuição temporária foi associada à melhora persistente do zumbido ao fim do tratamento (p = 0,002). CONCLUSÃO: Além da avaliação médica e audiológica, os pacientes com zumbido devem ser avaliados para: 1) presença de dor miofascial próxima à orelha; 2) lateralidade entre ambos os sintomas; 3) diminuição temporária do zumbido durante a palpação do músculo dolorido. O tratamento deste subgrupo de pacientes pode ter melhor prognóstico que os demais.


Chronic pain in areas surrounding the ear may influence tinnitus. OBJECTIVE: To investigate the efficacy of myofascial trigger point deactivation for the relief of tinnitus. METHOD: A double-blind randomized clinical trial enrolled 71 patients with tinnitus and myofascial pain syndrome. The experimental group (n = 37) underwent 10 sessions of myofascial trigger point deactivation and the control group (n = 34), 10 sessions with sham deactivation. RESULTS: Treatment of the experimental group was effective for tinnitus relief (p < 0.001). Pain and tinnitus relieves were associated (p = 0.013), so were the ear with worst tinnitus and the side of the body with more pain (p < 0.001). The presence of temporary tinnitus modulation (increase or decrease) upon initial muscle palpation was frequent in both groups, but its temporary decrease was related to the persistent relief at the end of treatment (p = 0.002). CONCLUSION: Besides medical and audiological investigation, patients with tinnitus should also be checked for: 1) presence of myofascial pain surrounding the ear; 2) laterality between both symptoms; 3) initial decrease of tinnitus during muscle palpation. Treating this specific subgroup of tinnitus patients with myofascial trigger point release may provide better results than others described so far.

ABSTRACT

OBJECTIVE:The aim of this cross-sectional study was to evaluate the relationship among pain intensity and duration, presence of tinnitus and quality of life in patients with chronic temporomandibular disorders (TMD). MATERIAL AND METHODS: Fifty-nine female patients presenting with chronic TMD were selected from those seeking for treatment at the Bauru School of Dentistry Orofacial Pain Center. Patients were submitted to the Research Diagnostic Criteria anamnesis and physical examination. Visual analog scale was used to evaluate the pain intensity while pain duration was assessed by interview. Oral Health Impact Profile inventory modified for patients with orofacial pain was used to evaluate the patients' quality of life. The presence of tinnitus was assessed by self report. The patients were divided into: with or without self report of tinnitus. The data were analyzed statistically using the Student's t-test and Pearson's Chi-square test, with a level of significance of 5%. RESULTS: The mean age for the sample was 35.25 years, without statistically significant difference between groups. Thirty-two patients (54.24%) reported the presence of tinnitus. The mean pain intensity by visual analog scale was 77.10 and 73.74 for the groups with and without tinnitus, respectively. The mean pain duration was 76.12 months and 65.11 months for the groups with and without tinnitus, respectively. The mean OHIP score was 11.72 and 11.74 for the groups with and without tinnitus, respectively. There was no statistically significant difference between groups for pain intensity, pain duration and OHIP scoreS (p>0.05). CONCLUSION: Chronic TMD pain seems to play a more significant role in patient 's quality of life than the presence of tinnitus.

ABSTRACT

A associação entre zumbido e hiperacusia é frequente na literatura. OBJETIVOS: Verificar a ocorrência e o efeito de supressão das emissões otoacústicas transientes (EOATs), a existência de associação entre graus de zumbido e de hiperacusia, entre efeito supressor das EOATs e lateralidade, graus de zumbido e de hiperacusia, em adultos normo-ouvintes com queixas de zumbido e hiperacusia. MATERIAIS E MÉTODOS: Foram incluídos, nesta forma de estudo transversal, 25 indivíduos normo-ouvintes com queixas de zumbido e hiperacusia. Utilizou-se o Tinnitus Handicap Inventory (THI) para classificação do grau do zumbido e o Loudness Discomfort Level (LDL) para o da hiperacusia. RESULTADOS: A ocorrência das EOATs variou de 33 por cento a 88 por cento. Houve 63,7 por cento de presença de efeito de supressão na orelha direita e 81,7 por cento na orelha esquerda. Não ocorreu correlação significativa entre os graus de zumbido e os graus de hiperacusia em ambas as orelhas e não houve associação significativa entre efeito de supressão das EOATs e lateralidade, grau de zumbido e de hiperacusia. CONCLUSÃO: A ocorrência de EOATs foi inferior à encontrada em adultos normo-ouvintes. Obteve-se maior percentual de presença do efeito de supressão das EOATs em ambas as orelhas. Não houve associação entre as variáveis analisadas.


The association between tinnitus and hyperacusis is common according to the literature. AIM: To verify the occurrence and the suppression effect of transient otoacoustic emissions (TEOAE), the existence of association between tinnitus degrees and hyperacusis degrees, and between the suppressive effect of TEOAE and laterality, tinnitus and hyperacusis degrees in normal hearing adults with complaints of tinnitus and hyperacusis. MATERIALS AND METHODS: 25 normal hearing subjects with complaints of hyperacusis and tinnitus were studied in this cross-sectional study. The Tinnitus Handicap Inventory (THI) was used for the classification of tinnitus degrees, and the Loudness Discomfort Level (LDL) for the hyperacusis classification. RESULTS: The occurrence of TEOAE ranged from 33 to 88 percent. We observed the presence of TEOAE suppression effect on 63.7 percent in the right ear and 81.7 percent in the left ear. There was no significant correlation between the degrees of tinnitus and hyperacusis in both ears. No statistically significant associations between the TEOAE suppression effect and laterality, tinnitus degrees and hyperacusis degrees were found. CONCLUSION: The occurrence of TEOAE was lower than that found in normal hearing adults. A higher percentage of the presence of TEOAE suppression effect has been found in both ears. No association between the variables was observed.

ABSTRACT

Tinnitus describes the sensation of any sound perceived in the head or in the ears without any evidentstimulus. It may be associated with any form of sensorineural hearing impairment but difficulty in hearingis the major determinant of tinnitus, followed by aging and exposure to noise. Somatic tinnitus is a type ofsubjective tinnitus in which the frequency or intensity is altered by body movements such as clenching thejaw, turning the eyes, or applying pressure to the head and neck. This article reviews the literature aboutthe possible etiologic factors associated with tinnitus, including temporomandibular disorders, while alsopresenting a clinical case in which tinnitus could be associated with myofascial pain. Adequate diagnosisand treatment planning of the clinical case are presented and discussed as well.


O zumbido é descrito com uma sensação de qualquer tipo de som percebido na cabeça ou ouvidos sem nenhum estímulo evidente. Pode estar associado com alguma forma de deficiência auditiva neurossensorial, mas a dificuldade de audição é o maior fator determinante do zumbido, seguido do envelhecimento e da exposição a ruídos. O zumbido somático é um tipo de zumbido subjetivo cuja frequência ou intensidade é alterada por movimentos do corpo, como fechamento da mandíbula, movimento dos olhos ou aplicação de pressão na cabeça e pescoço. Este artigo faz uma revisão da literatura sobre os possíveis fatores etiológicos associados ao zumbido,incluindo disfunções temporomandibulares, além de apresentar um caso clínico no qual o zumbido pode ser associado à dor miofascial. O adequado diagnóstico e o plano de tratamento do caso clínico também são apresentados e discutidos.

ABSTRACT

Introdução: A correlação da perda auditiva com o zumbido pode ser justificada se considerarmos que esta é o fator desencadeante do zumbido, uma vez que danos ou degenerações da orelha interna e do nervo vestibulococlear podem ser geradores do zumbido. Segundo os diferentes relatos, 85 a 96% dos pacientes com zumbido apresentam algum grau de perda auditiva. Objetivo: Correlacionar o sexo, idade, grau e tipo de perda auditiva com o incômodo ocasionado pela presença do zumbido dos pacientes da clínica de Dispositivos Eletrônicos Aplicados a Surdez. Método: Estudo retrospectivo de natureza exploratória de 100 prontuários de indivíduos regularmente matriculados na Clínica de Fonoaudiologia da Faculdade de Odontologia de Bauru, Universidade de São Paulo FOB/USP com uso do instrumento THI (Tinnitus Handicap Inventory). Resultados e Conclusão: O sexo, a idade assim como o grau de perda auditiva não possuem influência sobre o incômodo gerado pelo zumbido, porém a ocorrência da perda auditiva em portadores de zumbido é progressivamente maior conforme o avanço da idade e em indivíduos com perda auditiva do tipo sensorioneural.


Introduction: The correlation between hearing loss with tinnitus can be justified if we consider that this is a tinnitus-causing factor, since the impairments or degenerations on the inner ear and the vestibulocochlear nerve can cause the tinnitus. According to different reports, 85%-96% of patients with tinnitus show some degree of hearing loss. Objective: To correlate the sex, age, degree and type of hearing loss with the tinnitus disorder in patients at the Electronic Devices-related Clinic of Deafness). Method: Retrospective study of exploratory nature in 100 individuals' records duly registered at the Phonoaudiology Clinic of University of São Paulo's Dentistry School in Bauru FOB/USP, by using the THI instrument (Tinnitus Handicap Inventory). Results and Conclusion: Sex, age and degree of hearing loss do not have an influence over the tinnitus disorder, but the hearing loss in tinnitus listeners is progressively bigger according to age and in individual with neurosensorial hearing loss.
