The effects of photobiomodulation therapy in individuals with tinnitus and without hearing loss.

To verify the effect of photobiomodulation therapy (PBMT) in individuals with chronic tinnitus without hearing loss, 20 patients who met the inclusion criteria were randomly divided into group 1: active low-level laser (LLL) and group 2: equipment without laser (placebo). Upon anamnesis, data collection, and audiological exams, the Tinnitus Handicap Inventory (THI) and the Visual-Analog Scale (EVA) were applied to measure the level of discomfort with tinnitus and the level of discomfort before and after laser treatment. The protocol used included 12 active LLL sessions for group 1 and not active for group 2, varying red and infrared wavelengths. There was a reduction in the disadvantage of individuals with tinnitus after the intervention and between the initial and final sessions, regardless of the intervention, although group 1 showed a greater reduction than group 2, regardless of point in time of assessment and number of session. There was no statistical difference as to group and point in time for the high-frequency audiometry and acuphenometry outcomes. Individuals with chronic tinnitus reduced the complaint, regardless of point in time and group of intervention; however, the group that received PBMT improved the level of satisfaction, regardless of point in time of assessment and number of session.

The average of responses to all applied questions rated the website as "superior". Conclusion The website development was validated for online availability.

Comparative analysis between effective gain and functional gain in bone-anchored hearing aid users.

BACKGROUND: The cases of ear malformations, conductive, mixed, and single-sided deafness hearing loss are candidates for surgery and use of Bone-Anchored Hearing Aids (BAHA). Commonly, the literature highlights two procedures to assess the benefits and characteristics of amplification in users: functional gain (FG) and effective gain (EG). OBJECTIVE: Estimate and compare the EG and the FG to evaluate the benefits obtained by users of BAHA and, later, to compare tests of speech perception in silence and in noise. METHODOLOGY: The sample (n=79) was divided into four groups, implanted from February 2014 to February 2021. The following tests were analyzed: pure-tone audiometry by air and bone; research of audiometric thresholds in free field; speech perception tests in silence and in noise. RESULTS: EG presented lower values than FG in all frequencies. The positive results of the speech perception tests were correlated with worse FG values. EG is the best method for evaluation, as it allows a proper comparison between devices, as well as a comparison with the prescription of validated rules. CONCLUSIONS: A better evaluation of results was observed on the EG values, indicating that it is a relevant method to assess auditory performance. In addition, the FG results were incompatible with the benefits obtained in the speech perception tests, showing that it is not a reliable tool for monitoring the results with the use of BAHA.

Hearing performance of individuals with minimal hearing loss in complex and realistic communication experiences. / Desempenho auditivo de indivíduos com perda auditiva mínima em experiências complexas e realistas de comunicação.

PURPOSE: To analyze hearing performance and expectations regarding the use of hearing aids (HA) by participants with minimal hearing loss. METHODS: This research is a primary, observational, longitudinal and prospective study. Two questionnaires, the Speech Spatial Qualities Questionnaire (SSQ) and the Expected Consequences of Hearing Aid Ownership (ECHO), were used, respectively, to verify hearing performance in complex listening situations and expectations regarding the use of HA. The convenience sample consisted of adults aged 53 to 72. RESULTS: SSQ showed that, for hearing performance, greater difficulties were observed in unfavorable situations such as speech and speech-in-noise, followed by greater ease in locating the sound source and in the quality and naturalness of the sound. ECHO showed that, for the expectations regarding the use of the HA, the variables with significant correlation values were age x general expectation with HA and age x HA's positive aspects. No statistically significant association existed between performance scores in complex listening situations and the analyzed variables. CONCLUSION: Minimal hearing loss can negatively influence everyday communicative situations, and the expectation of individuals with minimal hearing loss regarding the use of HA was shown to be high. In addition, the hearing performance of individuals in this study did not show correlations with the age, gender and education level of the sample.

Para as expectativas quanto ao uso do dispositivo de amplificação, as variáveis com valor de correlação significativa foram idade expectativa geral com o uso do AASI, e idade em relação aos seus aspectos positivos. Não houve associação estatisticamente significativa entre os scores de desempenho em situações complexas de escuta e as variáveis analisadas. CONCLUSÃO: A perda auditiva mínima pode influenciar negativamente em situações comunicativas cotidianas, como também, a expectativa dos indivíduos com perda auditiva mínima quanto ao uso do AASI mostrou-se elevada. Além disso, o desempenho auditivo nos indivíduos desse estudo não apresentou correlações com idade, gênero e escolaridade da amostra.

Salivary Cortisol and Sustained Auditory Attention in Children with and without Cleft Lip and Palate.

Introduction Cortisol is a hormone involved in the response to stress. Attention is a function that can change due to exposure to stress. Objectives To verify the correlation between the level of salivary cortisol and sustained auditory attention in children with cleft lip and palate, as well as to compare the results of the variables analyzed between female and male patients. Methods In total, 103 children aged 6 to 11 years, were divided into 2 groups: those with cleft lip and palate (experimental group, EG; n = 69) and the control group (CG; n = 34). The Sustained Auditory Attention Ability Test (SAAAT) and salivary cortisol levels, measured by an enzyme immunoassay kit (Salimetrics, Stage College, PA, US), were calculated and compared regarding the two groups. The statistical tests used were the Mann-Whitney test and the Spearman correlation. Results The median level of salivary cortisol was of 0.03615 µl/dL and 0.18000 µl/dL respectively for the EG and CG, with a significant difference between the groups ( p = 0.000). Absence of statistical significance (total error score = 0.656; vigilance decrement = 0.051) was observed the for SAAAT among the EG (median total error score = 12.00; 25th percentile [25%] = 7.00; 75th percentile [75%] = 21.00; and vigilance decrement = 1.00; 25% = 0.00; 75% = 2.50) and the CG (median total error score = 12.00; 25% = 6.00; 75% = 24.00; and vigilance decrement = 0.00; 25% = -1.00; 75% = 2.00). Conclusion All children had median levels of salivary cortisol and scores for sustained auditory attention within normal parameters. A significant correlation between the level of salivary cortisol and the ability to sustain auditory attention was observed in children without cleft lip and palate. There were no differences regarding the SAAAT and salivary cortisol between female and male patients.

Association of tinnitus and self-reported systemic arterial hypertension: a retrospective study. / Associação do zumbido e a hipertensão arterial sistêmica autorreferida: estudo retrospectivo.

PURPOSE: To describe data on hearing loss, systemic arterial hypertension and tinnitus of individuals, and to verify the association between self-reported systemic arterial hypertension and tinnitus, as well as to correlate other variables present in the sample: hearing loss and tinnitus, age and tinnitus and age and systemic arterial hypertension. METHODS: Quantitative, descriptive and inferential, retrospective research with data collection from 473 medical records of adults and elderly people treated between 2008 and 2018. Selected were information on age, gender, result of pure tone audiometry, tinnitus, tinnitus type and frequency, presence of SAH and use of medication to control the disease. RESULTS: No association was found between systemic arterial hypertension and tinnitus or between hearing loss and tinnitus and between age and tinnitus, however, an association was observed between age and systemic arterial hypertension using the Chi - Square test. The most common type of tinnitus was wheezing and most individuals who reported feeling more than one type of tinnitus were hypertensive. CONCLUSION: The results found and the literature suggest that systemic arterial hypertension may be an additional factor or an aggravating factor of preexisting factors in the generation of tinnitus, but not the primary cause.

OBJETIVO: Descrever dados da perda auditiva, da hipertensão arterial sistêmica e do zumbido dos indivíduos, e verificar a associação entre hipertensão arterial sistêmica autorreferida e zumbido, bem como correlacionar outras variáveis presentes na amostra: perda auditiva e zumbido, idade e zumbido e idade e hipertensão arterial sistêmica. MÉTODO: Pesquisa quantitativa, descritiva e inferencial, retrospectiva com coleta de dados de 473 prontuários de adultos e idosos atendidos entre os anos 2008 e 2018. Selecionadas informações sobre idade, gênero, resultado da audiometria tonal liminar, zumbido, tipo e frequência do zumbido, presença de HAS e uso de medicamento para controle da doença. RESULTADOS: não foi encontrada associação entre hipertensão arterial sistêmica e zumbido ou entre perda auditiva e zumbido e entre idade e zumbido, todavia foi observada associação entre idade e hipertensão arterial sistêmica, por meio do teste Qui Quadrado. O tipo de zumbido mais comum foi o chiado e a maioria dos indivíduos que referiram sentir mais de um tipo de zumbido eram hipertensos. CONCLUSÃO: os resultados encontrados e a literatura sugerem que a hipertensão arterial sistêmica pode ser um fator adicional ou um agravante de fatores preexistentes na geração do zumbido, porém não a causa primária.

Preliminary Study of the Applicability of Software in the Investigation of Sustained Auditory Attention.

Introduction The use of auditory behavioral tests, which specifically assess sustained attention, is necessary, due to its relationship with learning, language production, cognitive development and school performance. Objective To evaluate how children performed using software developed to investigate the ability of sustained auditory attention, and to compare the scores obtained in this format with those of the original, non-computerized test. Methods This cross-sectional study included 52 children of both genders, aged 6 to 11 years, with normal hearing and no history of complaints regarding inattention and/or hyperactivity. The computerized test was administered to all 52 children. The total error score (inattention and impulsivity) and the vigilance decrement were used to define the children's performance when using the software. The scores obtained in the two formats (computer software and original on compact disc) were then compared. Results Statistically significant differences were found in the scores for innattention, impulsivity, and total error score (inattention and impulsivity) when comparing genders, and a negative correlation coefficient was found when comparing ages. Increased scores were found for all variables of the sustained auditory attention ability test (SAAAT) compared with the original format. Conclusion Females performed worse than males in all aspects except for vigilance decrement when using the SAAAT software developed to evaluate the ability of SAAAT vigilance; younger children made more errors when using the SAAAT software; inattention errors were more frequent than impulsivity. Overall, higher values were obtained using the SAAAT software, when compared with the original version.

Tinnitus and hearing survey: cultural adaptation to Brazilian Portuguese.

INTRODUCTION: Hearing loss is associated with several comorbidities and may be frequently associated with tinnitus. When patients complain of both tinnitus and hearing difficulties in audiology and otolaryngology clinics, there, is often great difficulty separating the two complaints. The tinnitus and hearing survey was specially developed for this purpose to identify the main complaint and help direct the choice of appropriate intervention. OBJECTIVE: To translate and culturally adapt the tinnitus and hearing survey for the Brazilian-Portuguese. METHODS: Seventy patients who had previously completed a battery of audiological diagnostic exams were invited to complete the tinnitus and hearing survey and were categorized into four groups: normal hearing without tinnitus, normal hearing with tinnitus, hearing loss without tinnitus, and hearing loss with tinnitus. Cultural adaptation of tinnitus and hearing survey followed the steps indicated by Guillemin et al. (1993), including assessment of inter-researchers' reproducibility, internal consistency, and reliability of the instrument. RESULTS: There were no substantial changes to the content of the tinnitus and hearing survey questions, although a few adaptations were made to two-item sound tolerance section to facilitate participants' understanding. Internal consistency and reliability tested by Cronbach's α was considered good for all domains. The reproducibility of the tinnitus and hearing survey was measured by the Kappa coefficient at two different moments and agreement between evaluators 1 and 2 was considered almost perfect, indicating good reproducibility. CONCLUSION: The tinnitus and hearing survey was culturally adapted to Brazilian Portuguese and analyzed for internal consistency, reliability, and reproducibility. Results support this questionnaire as a useful tool to help professionals differentiate the main complaint of the individual, allowing the choice of a more appropriate intervention.

The applicability of the Tinnitus and Hearing Survey (THS) in the differentiation of tinnitus and hearing complaints. / Aplicabilidade do Tinnitus and Hearing Survey (THS) na diferenciação de queixas auditivas.

PURPOSE: To verify the applicability of the Tinnitus and Hearing Survey (THS) to measure the different complaints of tinnitus, hearing loss and sound tolerance. METHODS: THS was performed, composed of 4 questions about tinnitus, 4 about hearing loss and one about sound tolerance. Previously, all participants performed a battery of audiological diagnostic tests and were then divided into 4 groups: Bilateral normal audiometry with mean up to 25dB, with and without tinnitus complaint (Groups 1 and 3); diagnosis of mild to moderate neural sensory hearing loss (26dB to 60dB), no previous use of individual hearing aids, complaining of chronic tinnitus (≥6 months) and individuals without tinnitus complaints (Groups 2 and 4); and age ≥18 years old. RESULTS: Seventy subjects were included in the present study. Regarding the analysis of the total between the groups by the Kruskal-Wallis test, significant differences were found in the sections about tinnitus and hearing loss, but there was no significance in the section regarding sound tolerance. Regarding the questions in Section A of the THS, only Groups 3 and 4 scored the highest. Regarding the questions related to Section B about hearing loss, the groups without hearing loss (Groups 1 and 3) scored the lowest. In relation to the question of the THS in Section C, Group 3 scored the highest. CONCLUSIONS: The THS questionnaire proved to be a useful, quick and simple tool to assist the audiologist in the understanding and differentiation of the audiologic complaints.

OBJETIVO: verificar a aplicabilidade do THS em mensurar e diferenciar as queixas de zumbido, perda auditiva e tolerância ao som. MÉTODO: Foi aplicado o questionário THS, composto por 4 questões sobre zumbido, 4 sobre perda auditiva e 1 sobre tolerância ao som. Previamente, todos os participantes realizaram uma bateria de exames de diagnóstico audiológico e foram divididos em grupos: audição normal bilateral com média até 25dB, com e sem queixa de zumbido (Grupos 1 e 3); diagnóstico de perda auditiva sensório neural de grau leve a moderado (26dB a 60dB), sem uso prévio de aparelho de amplificação sonora Individual (AASI), com queixa de zumbido crônico (≥6 meses) e também indivíduos sem queixa de zumbido (Grupos 2 e 4); idade igual ou superior a 18 anos. RESULTADOS: Foram incluídos no presente estudo 70 indivíduos. Em relação a análise do total entre os grupos pelo teste Kruskal-Wallis foram encontradas diferenças significativas nas seções sobre zumbido e perda auditiva, mas não houve significância da seção sobre tolerância ao som. Em relação às questões sobre zumbido apenas os grupos 3 e 4 pontuaram. Quanto às questões referentes à perda auditiva, os grupos sem perda (grupos 1 e 3) foram os que menos pontuaram. Em relação a questão do THS sobre tolerância ao som, o grupo 3 foi o que mais pontuou. CONCLUSÃO: o questionário THS se mostrou como uma possível ferramenta para auxiliar na compreensão e diferenciação das queixas auditivas.

Development and Evaluation of Portal do Zumbido : A Novel Telehealth Approach to Tinnitus.

Introduction Tinnitus is a prevalent symptom in audiological clinics, and the speech therapist participates in the assessment, diagnosis, and intervention of tinnitus. A range of studies have been developed with the aim to promote auditory health, and telehealth is an option for this purpose. Objective The aim of the present study was to develop and assess a virtual platform for tinnitus management for speech therapists. Methods The present study provided a distance-learning-course, with the aid of Portal do Zumbido , available in the following electronic address: zumbido.fob.usp.br. Infographics were available for download, and modules were made to comprise the introduction to the symptoms, assessment, and intervention for tinnitus. Results Speech therapists of different regions of Brazil received an e-mail invitation to participate and to assess the platform, 46 of whom registered. From the 46 speech therapists registered, 38 assessed the virtual platform with the aid of a questionnaire about the theoretical content and then answered a motivational research sheet (MRS). The speech therapists correctly answered 90% and 100% of the questions in the questionnaire and in the MRS, respectively, which may indicate that the professionals positively absorbed the content; thus, the content was considered to be impressive when the MRS was analyzed. Conclusion Portal do Zumbido was developed and is available for access in the following electronic address: zumbido.fob.usp.br. Furthermore, the platform received a positive assessment by the speech therapists who participated in the present study.

Sound Generator: Analysis of the Effectiveness of Noise in the Habituation of Tinnitus.

Introduction Tinnitus is a disorder that affects 10 to 15% of de world's population. Sound therapy performed through hearing aids (HAs) with integrated sound generator (SG) is one of the forms of tinnitus treatment. Objective To analyze the effectiveness of four masking noises in relieving tinnitus in individuals with mild and moderate bilateral sensorineural hearing loss and their influence in speech perception. Methods The participants were 35 individuals with tinnitus and mild and moderate bilateral sensorineural hearing loss, divided into four groups. All groups underwent HA and SG adaptation, being regulated in the combined mode (HA and SG). In group 1 (G1), the white noise stimulus was applied, in group 2 (G2), pink noise was applied, in group 3 (G3), speech noise, and in group 4 (G4), the high tone was applied. All patients were subjected to the following procedures: audiological diagnosis, acuphenometry, tinnitus handicap inventory (THI), visual analogue scale (VAS), and hearing in noise test (HINT). The procedures were performed prior to and after hearing intervention, and after 3 months of use of HA and SG. Results All groups presented a statistically significant difference for the THI, VAS, and HINT pre and postintervention. In the case of the HINT, only pink noise presented a significant difference. However, in the comparation among groups there was no significant difference. Conclusion The present study made it possible to conclude that the four noises were equally effective in relieving tinnitus, with no statistically significant differences between the analyzed groups.

Effects of Low-Level Laser Therapy as a Therapeutic Strategy for Patients With Tinnitus: A Systematic Review.

Purpose This systematic review aimed to analyze the effects of low-level laser therapy (LLLT) on the severity of tinnitus when compared to no therapy or other modalities of therapies. Method A systematic review protocol was registered at the International Prospective Register of Systematic Reviews (PROSPERO) under the Registration Number CRD42019119376. A search was performed in each of the following databases: EMBASE, LILACS, PubMed, Science Direct, Scopus, Web of Science, Google Scholar, and ProQuest. The inclusion criteria consisted of studies in adults over 16 years of age, randomized clinical trials in which subjects presented chronic (≥ 6 months) and subjective tinnitus (unilateral or bilateral) as well as with or without bilateral sensorineural hearing loss, and studies that used only LLLT for treatment of tinnitus compared to no-therapy group or other modalities of therapy. No language or time restrictions were stipulated. The references were managed by Endnote Web and Rayyan QCRI. Results After the screening process, seven studies remained that attained the eligibility criteria. Regarding the risk of bias, only one study was categorized as low risk of bias; the six remaining studies were classified as moderate risk of bias. The seven included studies mainly assessed the LLLT effects on tinnitus by Visual Analogue Scale, Tinnitus Handicap Inventory, pitch and loudness matching, minimum masking level, and pure-tone audiometry. All the seven selected studies found different degrees of significant results regarding tinnitus severity; however, there was no consensus among the results. Conclusion Even though the LLLT showed positive effects in the tinnitus severity in some studies, it is not possible yet to make any recommendation over its uses for the treatment of tinnitus severity.

Adult Perfomance on the Sustained Auditory Attention Skill Test.

Introduction The Sustained Auditory Attention Ability Test (SAAAT) is an instrument used to assess sustained auditory attention in children. Difficulties related to this ability are not unique to children alone, as adults have been observed to present with the same deficits. Therefore, there is a need to adapt instruments like the SAAAT and provide reference values for adults. Objective To assess adult performance on the SAAAT. Methods Approved by the Human Research Ethics Committee under n° 034/2011. The sample consisted of 30 participants aged between 18 and 30 years old (average age = 24.2 years old), female and male. The inclusion criteria were: peripheral hearing within normal limits, type A tympanometric curve, and no attention-related complaints. The participants were submitted to Tonal Audiometry, Logoaudiometry, Immitanciometry and to the SAAAT. Results The following mean values and standard deviations (SD) were observed: inattention = 1.7 (SD = 2.2) and impulsivity = 0.8 (SD = 0.9) error types. For the SAAAT, the mean value for the total error score was 2.4 (SD = 2.6), and for the decrease in vigilance, it was 0.3 (SD = 0.5). When comparing the performance of adults and children, a statistically significant difference was observed for inattention ( p = 0.000) and impulsivity ( p = 0.001) error types, as well as in the total error score ( p = 0.000) and in decreased vigilance ( p = 0.0003). Conclusion The performance of adults in the SAAAT differed from the children's parameters, since adults showed lower scores in all variables of the instrument.

Applicability of the real ear measurement for audiological intervention of tinnitus.

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.

Audiological findings in the Vogt-Koyanagi-Harada Syndrome. / Achados audiológicos na Síndrome de Vogt-Koyanagi-Harada.

The Vogt-Koyanagi-Harada syndrome (VKHS) is a rare, multisystemic and autoimmune disease. The syndrome mainly affects the eyes, followed by bilateral chronic panuveitis, however, the syndrome may also affect the melanocytes tissues, for example, the eyes, inner ear, meninges and skin. The syndrome origin mechanism is not yet completely known. Commonly, the specific ethnic groups that are affected by the VKHS are as follows: Hispanics, Asians, Indians, Native Americans and ethnic groups from the Middle East. The audiological characteristics of the syndrome and the possible audiologist interventions for a specific case will be reported. The patient was attended at the Clinic of Speech Therapy, Faculdade de Odontologia de Bauru (FOB). She is 53 years old and presented audiological complaints. She was diagnosed with VKHS by a specialist doctor. Throughout the audiologist assessment, she presented bilateral sensorineural hearing loss, absent otoacoustic evoked emissions, complaints about postural vertigo and acute tinnitus. The specific case reported presented sudden sensorineural hearing loss, vertigo, tinnitus and bilateral ocular disease. Even though drug treatment was performed, the hearing loss remained. Therefore, before the hearing aid (HA) fitting, the audiologist should perform the hearing management, investigate if the patient takes the drug treatment and the occurrence of suggestive symptoms of the syndrome. These are some points that help in the reference to the specialist doctor and the audiologist strongly participates in what concerns the hearing.

A síndrome de Vogt-Koyanagi-Harada (SVKH) é rara, multissistêmica e autoimune. Atinge principalmente os olhos, provocando uma panuveíte crônica bilateral, porém traz afecções em outras áreas e tecidos que são ricos em melanócitos, como olhos, orelha interna, meninges e a pele. Sua origem ainda não é totalmente conhecida. Geralmente, a SVKH atinge indivíduos de origem hispânica, do Oriente Médio, indianos, nativos americanos e asiáticos. Descrição dos aspectos audiológicos acometidos pela síndrome e as possíveis intervenções fonoaudiológicas para um caso específico. Paciente de 53 anos, sexo feminino, compareceu à Clínica de Fonoaudiologia, Faculdade de Odontologia de Bauru (FOB) com queixas audiológicas e diagnóstico médico da SVKH. A paciente apresentou perda auditiva sensório-neural bilateralmente, emissões otoacústicas evocadas ausentes e queixas vestibulares de vertigem postural e desequilíbrio ao andar, bem como queixa de zumbido agudo contínuo. O caso apresentado mostrou perda auditiva sensório-neural, vertigem, zumbido e acometimento ocular bilateral. Apesar do tratamento com corticoesteroide, a perda auditiva se manteve. Desta forma, precedente à indicação do AASI, o fonoaudiólogo deve atentar-se para o acompanhamento audiológico do caso, realização ou não de tratamento medicamentoso e ocorrência de sintomas sugestivos da síndrome, favorecendo o encaminhamento para o médico e participando ativamente do processo terapêutico envolvendo a audição.

Analysis of speech perception with amplification devices in subjects with ear malformation and unilateral hearing loss. / Análise da percepção da fala com uso de dispositivos de amplificação em indivíduos com malformação de orelha e perda auditiva unilateral.

PURPOSE: To verify the speech perception in subjects with ear malformation and unilateral hearing loss, fitted with two types of amplification as follows: conventional hearing aids and softband (band with vibrator bone). METHOD: The study included fifteen subjects of both sexes who presented congenital malformation of the middle or outer ear, diagnosed with unilateral conductive or mixed hearing loss, moderate to severe hearing loss, age range between 15 to 25 years and, prescription from a specialist doctor for hearing device fitting. We performed the speech perception assessment without amplification after the hearing aid and softband fitting, with the hearing aid linked to the bone vibrator (conventional) and the softband (band with the bone vibrator). The subjects were evaluated using the Hearing in Noise Test (HINT), in silence and in noise. RESULTS: Seven subjects with unilateral ear malformation were evaluated, 57.1 % had impairment in the right ear and 42.9 % in the left ear. Regarding the type and the level of hearing loss, 71 % of all subjects included in the sample presented moderate conductive hearing loss. The assessment of speech perception was performed during silence, frontal noise, lateral noise and, during three specifics situations: no amplification, with conventional hearing aid and with the softband. The results with the amplification devices were positive in all evaluated conditions. CONCLUSION: Evaluated subjects presented improvement in speech perception, in silence, frontal noise and lateral noise situations, regardless of the type of amplification; however, the difference was not statistically significant.

The use of remote microphone systems in unilateral hearing loss: a preliminary study among Brazilian children and teenagers.

Due to the large number of individuals with Unilateral Hearing Loss (UHL) and the recommendation to use hearing assistive devices, studies are required to define possibilities of intervention for this population. OBJECTIVE: To evaluate the performance of the Remote Microphone System (RMS) in children with UHL. METHODOLOGY: Prospective clinical study with a convenience sample. Eleven children (mean age of 9.2 years) with severe and profound sensorineural UHL, hearing aid users and enrolled in regular schools participated in the study. They were evaluated using the Hearing in Noise Test (HINT), the Classroom Participation Questionnaire (CPQ), and the Sustained Auditory Attention Ability Test (SAAAT) with RMS. RESULTS: HINT results were analyzed using variance to three criteria of repeated measures, which revealed differences between intervention, position, and time factors and significant interaction between these three factors. The comparative analysis of the results from CPQ showed significant differences in the statistical t-test (p=<0.001) for all subscales. The analysis of variance at two repeated measures criteria used in the study of SAAAT revealed a difference between intervention and time, and both interacted significantly. CONCLUSION: The RMS associated with a hearing aid was effective for individuals with UHL.
