Translation and cultural adaptation of "Glasgow Children's Benefit Inventory" into Brazilian Portuguese

Abstract Objective Translate and cross-culturally adapt into Brazilian Portuguese the Glasgow Children's Benefit Inventory instrument used for the quality-of-life assessment after pediatric ENT interventions. Method This is a methodological study of translation and cross-cultural adaptation of the GCBI instrument following seven stages: 1) Translation of two versions by two independent translators, 2) Elaboration of a consensual synthetized version, 3) Assessment of the synthetized version by experts, 4) Assessment by the target audience, 5) Back-translation, 6) Pilot study and 7) Use of the instrument. The final version of the instrument was answered by a sample of 28 people responsible for children aged from 2 to 7 years, submitted to tonsillectomy between January 2019 and December 2021, in a public hospital in Porto Alegre. The collection considered patients with a minimum of 6-months and a maximum of 3-years of postoperative follow-up. Result The instrument final version was compared to the original version showing semantic equivalence, absence of consistent translation difficulties and appropriate cross-cultural adaptation, and well understood by the target audience. The application of the questionnaire in the sample showed a Cronbach alpha coefficient of 0.944 corresponding to a high degree of reliability of the instrument. Conclusion The translation and cross-cultural adaptation showed semantic appropriateness and its use when assessing ENT postoperative results in a pediatric population showed high reliability of the instrument. Level of evidence 4.

Critical analysis of moderate and severe retractions in the pars tensa and pars flaccida of the tympanic membrane,

Abstract Objectives: Analyze the prevalence of retractions in different areas of the Tympanic Membrane (TM), the correlations between the involvement of the Pars Tensa (PT) and Pars Flaccida (PF), and the air-bone gaps. Methods: A cross-sectional study. Patients with moderate and/or severe TM retraction of 2200 consecutive patients with chronic otitis media between August 2000 and January 2019 were included. Ears with previous surgery were excluded. Ears were classified as isolated PF and PT retractions and association of both. The degrees of severity and presence of effusion were evaluated. The data were analyzed using the SPSS Statistics software program. Results: 661 ears were included. The prevalence of isolated atical retractions was 24.9%, of isolated posterior quadrants was 10.6%, and of association of quadrants was 64%. There was no correlation between the retractions in the different areas of the TM (posterior and attic quadrants: r = 0.13; p = 0.041; anterior and posterior quadrants: r = 0.23; p = 0.013, anterior and attic quadrants: r = 0.06; p = 0.043). Effusion was present in 30.7% of the ears. ABG median was lower in ears with PF retraction (6.25 dB HL) than PT retraction, isolated (15 dB HL) or not (13.75 dB HL; p < 0.05); 72% of the ears had an ABG ≤ 20dB HL. For severity of the retraction of PF, the ABG was similar across groups. For the PT, there was a global difference in the medians of ABG in terms of the degree of severity, with a moderate correlation. Conclusion: The prevalence of moderate and severe retractions was 24.5%; 64% of the ears had an association of affected regions. There was no correlation between the retraction in the different areas of the TM. We found a significant correlation between the severity of retraction and the worsening of ABG threshold, only for PT. Evidence level: 4.

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.

Influence of different aspects on psychoacoustic measurements of patients with chronic tinnitus / Influência de diferentes aspectos nas medidas psicoacústicas de pacientes com zumbido crônico

ABSTRACT Purpose: to verify the sex, age, tinnitus location, presence or absence of hearing loss, its degree, and the psychoacoustic measurements (pitch, loudness, minimum masking level [MML], and residual inhibition [RI]) of patients with chronic tinnitus and their relationships. Methods: the study included subjects of both sexes, aged 25 to 85 years, with complaints of chronic tinnitus, followed up at the health service where the research was conducted. They were submitted to medical history survey, basic audiological assessment, and pitch, loudness, RI, and MML research. The following statistical tests were used: chi-square test, Fisher's exact test, Wilcoxon-Mann-Whitney U test, Kruskal-Wallis test, and Spearman's correlation coefficient. The significance level was set at 5% (p≤0.05). Results: the type of tinnitus was associated with the presence or absence of hearing loss (HL), degree of HL, MML, and loudness; age was associated with the presence or absence of HL and its degree. There was a directly weak proportional correlation between loudness and MML, whereas the correlations between pitch and loudness, pitch and MML, and RI and MML were weak and inversely proportional. Conclusion: both the affected subjects and their tinnitus characteristics were heterogeneous. The results indicate that some variables influence one another, which also happens between psychoacoustic measurements.

RESUMO Objetivo: verificar o gênero, a idade, a localização do zumbido, a presença ou ausência de perda auditiva e seu grau, assim como as medidas psicoacústicas (pitch, loudness, nível mínimo de mascaramento e inibição residual) de pacientes com zumbido crônico e as suas relações. Métodos: o estudo incluiu sujeitos de ambos os gêneros, com idades entre 25 e 85 anos, com queixa de zumbido crônico e que realizassem acompanhamento em ambulatório especializado do Hospital de Clínicas de Porto Alegre. Foram submetidos a anamnese, avaliação audiológica básica, pesquisa de pitch, loudness, inibição residual (IR) e nível mínimo de mascaramento (NMM). Foram utilizados os seguintes testes estatísticos: Teste Qui-Quadrado, Teste Exato de Fisher, Teste U de Wilcoxon - Mann-Whitney, Teste Kruskal Wallis e Coeficiente de Correlação de Spearman. O nível de significância utilizado foi de 5% (p≤0,05). Resultados: houve associação entre a variável tipo de zumbido e presença ou ausência de perda auditiva (PA), grau de PA, NMM e loudness, assim como, entre idade e presença ou ausência de PA e seu grau. A loudness e o NMM apresentaram fraca correlação diretamente proporcional, ao passo que as correlações entre pitch e loudness, pitch e NMM e IR versus NMM apresentaram-se fracas e inversamente proporcionais. Conclusão: houve heterogeneidade entre as características do zumbido e dos indivíduos acometidos. Conclui-se, de acordo com os resultados expostos, que existe influência de algumas variáveis entre si, da mesma maneira que ocorre entre as medidas psicoacústicas.

RESUMO Objetivo Verificar benefícios do uso de próteses auditivas na autopercepção do zumbido em adultos e idosos sem experiência prévia de amplificação. Métodos O estudo incluiu indivíduos de ambos os sexos, com queixa de zumbido, acompanhados em hospital público. Aplicaram-se os seguintes exames e instrumentos para mensurar o zumbido e determinar o seu incômodo: pesquisa do pitch e loudness, Escala Visual Analógica (EVA), pesquisa do nível mínimo de mascaramento, inibição residual e Tinnitus Handicap Inventory (THI). As avaliações foram realizadas em duas etapas: antes da adaptação das próteses auditivas e após um mês de uso dos aparelhos. Resultados Dos 20 indivíduos participantes, 60% eram idosos. Verificou-se diferença na autopercepção do zumbido pré e pós-protetização, medido pelas escalas THI e EVA. Também se observaram diferenças nas medidas psicoacústicas, com exceção do pitch, antes e após a amplificação. Além disso, houve correlação entre o tempo de zumbido e a idade com os escores finais do THI. Conclusão O uso de próteses auditivas reduziu o incômodo provocado pelo zumbido, com alteração nas medidas psicoaústicas e no impacto na qualidade de vida.

ABSTRACT Purpose To verify the benefits of using hearing aids in self-perception of tinnitus in adults and elderly without previous experience of amplification. Methods The study included individuals of both gender, with tinnitus complaint, accompanied in public hospital. The following tests and instruments were used to measure tinnitus and determine its discomfort: pitch and loudness, Visual Analogue Scale (VAS), minimum masking level, residual inhibition and Tinnitus Handicap Inventory (THI). The evaluations were performed in two stages: before the adaptation of the hearing aids and after one month of use of the devices. Results Of the 20 participants, 60% were elderly. There was a difference in self-perception of tinnitus before and after hearing aid fitting, as measured by THI and VAS. Differences in psychoacoustic measures were also observed, with the exception of pitch, before and after amplification. In addition, there was a correlation between tinnitus time and age with final THI scores. Conclusion The use of hearing aids was determined to reduce the annoyance caused by tinnitus, with changes in psycho-acoustic measures and impact on quality of life.

Characteristics of 419 patients with acquired middle ear cholesteatoma / Características de 419 pacientes com colesteatoma adquirido de orelha média

Abstract Introduction: Cholesteatoma is a destructive lesion that can result in life-threatening complications. Typically, it presents with hypoacusis and continuous otorrhea as symptoms. Because it is a rare disease, there are few studies in Brazil describing the characteristics of patients with the disease. Objective: This study aimed to determine the prevalence of cholesteatoma in patients with chronic otitis media and describe clinical, audiological and surgical characteristics of patients with acquired middle ear cholesteatoma treated at a referral hospital in the public health system. Methods: Cross-sectional and prospective cohort study, including 1710 patients with chronic otitis media, treated between August 2000 and June 2015, without prior surgery. Detailed clinical history, videotoscopy, and audiometry were performed, in addition to review of medical records to search for surgical data. Cholesteatomas were classified according to their route of formation. Results: Of the patients with chronic otitis media, 419 (24.5%) had cholesteatoma; mean age of 34.49 years; 53.5% female and 63.8% adults. Bilateral cholesteatoma was observed in 17.1%. Anterior epitympanic cholesteatoma corresponded to 1.9%; posterior epitympanic, 32.9%; posterior mesotympanic, 33.7%; two routes, 14.8%; and indeterminate, 16.7%. The mean air-bone gap was 29.84 dB and did not differ between routes of formation. There were no correlations between gap size and patient age or duration of symptoms. Of the surgical cases, 16.8% underwent closed tympanomastoidectomy and 75.2% open tympanomastoidectomy. Conclusion: The prevalence of cholesteatoma in patients with chronic otitis media was 24.5% and it was more common in adults than in children. Posterior mesotympanic cholesteatoma was more frequent, with no difference in mean air-bone gap between the different routes of formation. In patients undergoing surgery, open tympanomastoidectomy was the procedure most frequently chosen.

Resumo Introdução: Colesteatoma é uma lesão destrutiva que pode levar a complicações potencialmente letais. Tipicamente, apresenta hipoacusia e otorreia contínua como sintomas. Por ser uma doença rara, existem poucos estudos no Brasil que descrevam as características destes pacientes. Objetivo: O presente estudo teve como objetivos determinar a prevalência de colesteatoma entre os pacientes com otite média crônica (OMC) e descrever as características clínicas, audiológicas e cirúrgicas dos pacientes com colesteatoma adquirido de orelha média atendidos em um hospital de referência do sistema público de saúde. Método: Estudo transversal e de coorte prospectivo, incluindo 1.710 pacientes com OMC, atendidos entre agosto de 2000 e junho de 2015, sem tratamento cirúrgico prévio. Foram feitas anamnese detalhada, videotoscopia e audiometria, além de revisão de prontuários para busca de dados cirúrgicos. Os colesteatomas foram classificados conforme sua via de formação. Resultados: Dos pacientes com otite média crônica, 419 (24,5%) apresentavam colesteatoma. Média de 34,49 anos; 53,5% do sexo feminino e 63,8% adultos. Colesteatoma foi observado bilateralmente em 17,1%. Os epitimpânicos anteriores corresponderam a 1,9%; os epitimpânicos posteriores a 32,9%; os mesotimpânicos posteriores a 33,7%; duas vias a 14,8% e indeterminados a 16,7%. A média tritonal dos gaps aeroósseos foi de 29,84 dB e não diferiu entre os grupos segundo as vias de formação. Não foram observadas correlações entre tamanho do gap e idade do paciente ou duração dos sintomas. Dos pacientes operados, 16,8% foram submetidos a timpanomastoidectomia fechada e 75,2% a timpanomastoidectomia aberta. Conclusão: A prevalência de colesteatoma em pacientes com otite média crônica foi de 24,5% e foi mais frequente em adultos do que em crianças. Os mesotimpânicos posteriores foram mais frequentes, não foi observada diferença na média dos gaps aeroósseos entre diferentes vias de formação. Nos pacientes submetidos a cirurgia, a timpanomastoidectomia aberta foi o procedimento escolhido.

Tinnitus in Elderly Individuals: Discomfort and Impact in the Quality of Life

Abstract Introduction Tinnitus is a symptom that affects mainly the elderly and can negatively influence their quality of life. Objective The objective of our study is to evaluate the existence of a relationship between the quality of life and the impact caused by tinnitus in elderly individuals, considering the age and gender variables. Method We conducted a cross-sectional study in elderly people of both genders who participate in the extension activities at the university. The evaluation was composed of anamnesis and WHOQOL-OLD instruments, to evaluate the quality of life, and Tinnitus Handicap Inventory (THI) for the evaluation of the tinnitus impact. Result We evaluated 36 elderly individuals with an average age of 68.6 ± 6.8 years old, 72.2 % of them were women. We verified that most of the subjects classified their tinnitus as weak (44.4%) ormedium (36.1%). The score average in the THI was 20 points, with predominant classification of tinnitus impact as negligible (41.7%) or mild (30.6%). In the WHOQOL-OLD, the average score was 15.6 ± 1.6 points (total score). The negative correlation between the THI score and the WHOQOL-OLD score was found in the sensory domain operation and total score. Conclusion The results obtained in the study prove that the quality of life of the elderly individuals evaluated is related to a discomfort caused by the tinnitus.

Assessment of Eustachian tube function in patients with tympanic membrane retraction and in normal subjects / Avaliação da função da tuba de Eustáquio em pacientes com retração de membrana timpânica e em indivíduos normais

Abstract Introduction The diagnosis of Eustachian tube dysfunctions is essential for better understanding of the pathogenesis of chronic otitis media. A series of tests to assess tube function are described in the literature; however, they are methodologically heterogeneous, with differences ranging from application protocols to standardization of tests and their results. Objective To evaluate the variation in middle ear pressure in patients with tympanic membrane retraction and in normal patients during tube function tests, as well as to evaluate intra-individual variation between these tests. Methods An observational, contemporary, cross-sectional study was conducted, in which the factor under study was the variation in middle ear pressure during tube function tests (Valsalva maneuver, sniff test, Toynbee maneuver) in healthy patients and in patients with mild and moderate/severe tympanic retraction. A total of 38 patients (76 ears) were included in the study. Patients underwent tube function tests at two different time points to determine pressure measurements after each maneuver. Statistical analysis was performed using SPSS software, version 18.0, considering p-values <0.05 as statistically significant. Results Mean (standard deviation) age was 11 (2.72) years; 55.3% of patients were male and 44.7% female. The prevalence of type A tympanogram was higher among participants with healthy ears and those with mild retraction, whereas type C tympanograms were more frequent in the moderate/severe retraction group. An increase in middle ear pressure was observed during the Valsalva maneuver at the first time point evaluated in all three groups of ears (p = 0.012). The variation in pressure was not significant either for the sniff test or for the Toynbee maneuver at the two time points evaluated (p ≥ 0.05). Agreement between measurements obtained at the two different time points was weak to moderate for all tests in all three groups of ears, and the variations in discrepancy between measurements were higher in ears with moderate/severe tympanic retraction. Conclusion In this study population, the mean pressure in the middle ear showed significant variation only during the Valsalva maneuver at the first time point evaluated in the three groups of ears. Normal ears and those with mild retraction behaved similarly in all tests. The tested maneuvers exhibited weak to moderate intra-individual variation, with the greatest variation occurring in ears with moderate/severe retraction.

Resumo Introdução O diagnóstico das disfunções da tuba auditiva é essencial para o melhor entendimento da patogênese da otite média crônica. A literatura descreve uma série de testes que avaliam a função tubária; contudo, tais exames são metodologicamente heterogêneos, com diferenças que variam desde os protocolos de aplicação até a padronização dos exames e seus resultados. Objetivo Avaliar a variação na pressão na orelha média em pacientes com retração da membrana timpânica e em indivíduos normais durante os testes de função tubária e também avaliar a variação intraindividual desses testes. Método Estudo observacional do tipo transversal e contemporâneo, no qual o fator em estudo foi a variação na pressão na orelha média durante os testes de função tubária (manobra de Valsalva, Sniff Test e manobra de Toynbee) em indivíduos normais e em pacientes com retrações timpânicas leves e moderadas/graves. Foram incluídos 38 pacientes (76 orelhas). Os pacientes foram submetidos, em dois momentos diferentes, a testes de função tubária para determinar as medidas de pressão após cada manobra. A análise estatística foi feita com o programa SPSS, versão 18.0, e consideramos como estatisticamente significativos os valores de p < 0,05. Resultados A média ± desvio padrão da idade foi de 11 ± 2,72 anos; 55,3% dos pacientes eram do gênero masculino e 44,7% do feminino. A prevalência de curvas timpanométricas do tipo A foi mais alta entre os participantes com orelhas normais e naqueles com retrações leves, enquanto as curvas timpanométricas do tipo C foram mais frequentes no grupo com retrações moderadas/graves. Observamos pressões aumentadas na orelha média durante a manobra de Valsalva no primeiro momento da avaliação nos três grupos de orelhas (p = 0,012). A variação na pressão não foi significativa para o Sniff Test, nem para a manobra de Toynbee nos dois momentos de avaliação (p ≥ 0,05). Consideramos que a concordância entre as determinações obtidas nos dois momentos diferentes foi fraca a moderada para todos os testes nos três grupos de orelhas e as variações em termos de discrepância entre as medidas foram maiores nas orelhas com retrações timpânicas moderadas/graves. Conclusão Na população estudada, a média das pressões na orelha média apresentou variação significante apenas durante a manobra de Valsalva no primeiro momento de avaliação, nos três grupos de orelhas. As orelhas normais e aquelas que apresentavam retração leve se comportaram de maneira similar nos testes. As manobras testadas exibiram uma variação intraindividual fraca a moderada e a maior variação ocorreu nas orelhas com retrações moderadas/graves.

Influência de fatores e hábitos pessoais na percepção do zumbido / Influence of factors and personal habits on the tinnitus perception

RESUMO Objetivo: investigar a localização e verificar a influência de fatores e hábitos na percepção do zumbido em pacientes com tal sintoma. Métodos: fizeram parte da amostra 740 indivíduos com queixa de zumbido, atendidos em ambulatório especializado de hospital universitário. Todos relataram a localização do zumbido em resposta a questionário, contendo também informações sobre fatores e hábitos causadores de melhora ou piora na percepção do zumbido. Os dados foram analisados estatisticamente. Resultados: o predomínio da localização foi em ambas as orelhas. A maior parte dos fatores investigados não modifica a percepção do zumbido para os pesquisados. Dentre os fatores que puderam ser relacionados à piora da percepção estão, principalmente, o silêncio e o período da noite, seguidos pela ansiedade. Por outro lado, ruído foi o fator mais referido como causador de diminuição da percepção do zumbido. Não foi verificada influência de idade e gênero. Conclusão: mais da metade dos sujeitos apresentaram queixa de zumbido bilateral e a maior parte das situações pesquisadas não provocam mudança na percepção do zumbido na população estudada. Destaca-se, contudo, que a presença de ruído ambiental auxilia na diminuição da sensação de incômodo ao zumbido, enquanto o silêncio, período da noite e a ansiedade contribuem para acentuá-la.

ABSTRACT Purpose: to investigate the location and to verify the influence of factors and personal habits in the tinnitus perception in patients with the symptom. Methods: 740 individuals with tinnitus, from an outpatient clinic of a university hospital were investigated. All of them reported the location in response to a questionnaire, also containing information about some factors and daily habits that causes improvement or worsening of tinnitus. The data were statistically analyzed. Results: the predominant location was in both ears. Most of the investigated factors does not change the perception of tinnitus for researched subjects. The silence, the nighttime and the anxiety were the factors that might be related to worsening of tinnitus perception. Moreover, the noise was referred as a factor that causes decrease of tinnitus perception. There was no influence of age and gender. Conclusion: more than half of the subjects had bilateral tinnitus and that most situations surveyed do not cause change in the tinnitus perception to the studied people. It is noteworthy, however, that the presence of ambient noise helps to reduce the feeling of tinnitus annoyance, as well as the silence, the period of night and the anxiety contribute to accentuate it.

Zumbido crônico: estudo em indivíduos com e sem perda auditiva / Chronic tinnitus: stydy in individuals with and without hearing loss

Introdução: O zumbido pode estar presente em indivíduos com audição normal. Objetivo: Analisar e comparar o zumbido e o incômodo provocado em indivíduos com e sem perda auditiva. Métodos: A amostra foi composta por pacientes que apresentaram zumbido crônico, com audição normal ou perda auditiva. A avaliação foi feita por médico otorrinolaringologista e fonoaudiólogo (avaliação audiológica e questionário Tinittus Handicap Inventory ­THI). Resultados: A amostra foi composta por 50 indivíduos com zumbido crônico, divididos em dois grupos (com e sem perda auditiva). As idades variaram entre 29 e 69 anos (média 52,50±9,64 anos). Os grupos eram semelhantes quanto à sexo, idade e localização do zumbido, diferenciando-se somente no que se refere a presença de perda auditiva. Em relação à pontuação no THI, encontrou-se diferença entre os grupos nas escalas funcional, emocional e no THI total. A acufenometria evidenciou diferença entre os grupos no pitch e loudness do zumbido. Conclusão: Indivíduos com perda auditiva apresentaram pontuação maior na escala funcional e emocional, assim como no somatório total do questionário THI evidenciando maior incômodo provocado pelo zumbido. Além disso, o zumbido em tais indivíduos apresentou pitch mais agudo e loudness maior do que encontrados nos indivíduos sem perda auditiva.

Introduction: Tinnitus in the ears may be present in individuals with normal hearing. Objective: Analyzing and comparing the tinnitus and the impact caused by it on individuals with and without hearing loss. Methods: The sample was constituted by patients with chronic tinnitus. The evaluation was done by otorhinolaryngologyst and audiologist (audiological evaluation and Tinnitus Handicap Inventory questionnaire ­ THI). Results: The sample consisted of 50 individuals with chronic tinnitus, divided into in two groups (with and without hearing loss). The ages ranges from 29 to 69 years (52,50±9,64 years). The groups were similar for age, sex, and location of tinnitus, differing only in relation to the presence of hearing loss. In relation to the THI score a difference was found between the groups on the functional, emotional scales and on the total THI. The acuphenometry showed a difference between the groups in the pitch and loudness of the tinnitus. Conclusion: Individuals with hearing loss showed a higher score on the functional and emotional scale, and on the total of the THI, evidencing greater discomfort caused by tinnitus. In addition, the tinnitus in such individuals showed a higher pitch and loudness than the ones found for the individuals without hearing loss.

Pitch and Loudness Tinnitus in Individuals with Presbycusis

Abstract Introduction Tinnitus is a symptom that is often associated with presbycusis. Objective This study aims to analyze the existence of association among hearing thresholds, pitch, and loudness of tinnitus in individuals with presbycusis, considering the gender variable. Methods Cross-sectional, descriptive, and prospective study, whose sample consisted of individuals with tinnitus and diagnosis of presbycusis. For the evaluation, we performed anamnesis along with otoscopy, pure tone audiometry, and acuphenometry to analyze the psychoacoustic characteristics of tinnitus individuals. Results The sample consisted of 49 subjects, with a mean age of 69.57 6.53 years, who presented unilateral and bilateral tinnitus, therefore, a sample of 80 ears. In analyzing the results, as for acuphenometry, the loudness of tinnitus was more present at 0dB and the pitch was 6HKz and 8HKz. Regarding the analysis of the association between the frequency of greater hearing threshold and tinnitus pitch, no statistical significance (p= 0.862) was found. As for the association between the intensity of greater hearing threshold and tinnitus loudness, no statistical significance (p= 0.115) was found. Conclusion There is no significant association between the hearing loss of patients with presbycusis and the pitch and loudness of tinnitus.

Pitch and Loudness from Tinnitus in Individuals with Noise-induced Hearing Loss

Abstract Introduction Tinnitus is one of the symptoms that affects individuals suffering from noise induced hearing loss. This condition can be disabling, leading the affected individual to turn away from work. Objective This literature review aims to analyze the possible association between gender and tinnitus pitch and loudness, the degree of hearing loss and the frequencies affected in subjects with noise-induced hearing loss. Methods This contemporary cohort study was conducted through a cross-sectional analysis. The study sample consisted of adults with unilateral or bilateral tinnitus, who had been diagnosed with noise-induced hearing loss. The patients under analysis underwent an otorhinolaryngological evaluation, pure tone audiometry, and acuphenometry. Results The study included 33 subjects with noise-induced hearing loss diagnoses, of which 22 (66.7%) weremen. Authors observed no statistical difference between gender and loudness/pitch tinnitus and loudness/pitch in subjects with bilateral tinnitus. Authors found an inverse relation between tinnitus loudness with intensity greater hearing threshold and the average of the thresholds and the grade of hearing loss. The tinnitus pitch showed no association with higher frequency of hearing threshold. Conclusion Data analysis shows that, among the individuals evaluated, the greater the hearing loss, the lower the loudness of tinnitus. We did not observe an association between hearing loss and tinnitus pitch.

Avaliação tomográfica das orelhas contralaterais de pacientes com otite média crônica grave / Tomographic evaluation of the contralateral ear in patients with severe chronic otitis media

Alguns estudos indicam uma tendência à bilateralidade da otite média crônica. Acredita-se que a orelha contralateral possa fornecer evidências da via de formação da doença da orelha mais afetada, ser um parâmetro da função da tuba auditiva e predizer o sucesso do tratamento. A tomografia computadorizada é um excelente teste para avaliar as estruturas do osso temporal e as alterações decorrentes da da otite média. OBJETIVO: Avaliar tomografias computadorizadas (TC) de osso temporal de pacientes com otite média crônica e descrever anormalidades na orelha contralateral. MÉTODO: Estudo de Prevalências (transversal). Avaliação das TC de 75 pacientes com otite média crônica de um hospital terciário de referência no Brasil por um neurorradiologista. RESULTADOS: A população foi constituída por 50,6% do sexo masculino, com idade média de 36 anos. Encontramos 54,7% de alterações na orelha contralateral claramente relacionadas com otite média crônica. DISCUSSÃO: A prevalência de alterações radiográficas nas orelhas contralaterais de pacientes com otite média crônica corrobora com estudos clínicos, histopatológicos e funcionais desenvolvidos pelo mesmo grupo de pesquisa e sugere que esta doença tem uma característica bilateral.

Some studies indicate a bilateral tendency of chronic otitis media. It is believed that the contralateral ear can provide evidences of the route of formation of ear disease in the most affected, be a parameter of Eustachian tube function and predict successful treatment. The CT scan is an excellent test to evaluate the structures of the temporal bone and the changes resulting from otitis media. OBJECTIVE: To evaluate Temporal Bone Computed Tomography of patients with chronic otitis media and describe abnormalities in the contralateral ear. METHOD: Cross-sectional study. Evaluation of CT scans of 75 patients with chronic otitis media from a tertiary referral hospital in Brazil by a neuroradiologist. RESULTS: Population was consisted of 50.6% males with a mean age of 36 years. We found 54.7% of changes in contralateral ear clearly associated with chronic otitis media. CONCLUSION: The prevalence of radiographic changes in the contralateral ears of patients with chronic otitis media corroborates with clinical, histopathological and functional resources developed by the same group that this disease has a bilateral feature.

Correlação da cadeia ossicular no transoperatório com achados histológicos de colesteatomas / Hystology findings' correlation between the ossicular chain in the transoperative and cholesteatomas

A Otite Média Crônica é definida pela presença de alterações teciduais inflamatórias irreversíveis na fenda auditiva. As lesões ossiculares são as mais prevalentes. OBJETIVO: Correlacionar o grau de comprometimento da cadeia ossicular, visualizada no transoperatório, com o grau histológico de inflamação e com a espessura da perimatriz de colesteatomas. TIPO DE ESTUDO: Estudo transversal. MÉTODOS: Descrições cirúrgicas de 71 pacientes foram revisadas. Colesteatomas coletados e fixados em formol 10 por cento e preparadas uma lâmina em Hematoxilina-Eosina e outra em Picrossírios. A leitura foi "cega", através de imagens digitais, no ImageProPlus. A análise estatística foi realizada através do coeficiente de Spearman, sendo considerados como estatisticamente significativos os valores de P≤0,05. RESULTADOS: Havia algum envolvimento da cadeia ossicular em 65 casos. O ossículo mais freqüentemente afetado era a bigorna, seguida pelo estribo e pelo martelo. Ao aplicarmos o coeficiente de Spearman entre o grau de comprometimento da cadeia ossicular com a idade do paciente à cirurgia, a espessura da perimatriz e o grau histológico de inflamação não foram detectadas correlações. CONCLUSÃO: Os nossos achados indicam que é praticamente universal o acometimento da cadeia ossicular na presença de colesteatoma. Não foi encontrada correção entre a erosão ossicular e os achados histológicos.

Chronic otitis media is hystopathologycaly defined as the presence of irreversible inflammatory tissue changes in the middle ear. Ossicular lesions represent the most prevalent change. AIM: to correlate the degree of ossicular chain changes seen during surgery with the inflammatory histological degree and the thickness of the cholesteatoma perimatrix. STUDY DESGN: Cross-sectional study. METHODS: Seventy-one descriptions of surgeries done in patients submitted to tympanomastoydectomy were reviewed. Cholesteatoma were collected and fixed in 10 percent formaldehyde. Two slides were made for each cholesteatoma, one stained with HE and another with picrossirius. Images were obtained from light microscopy and digitally processed and "blindly" analyzed using Image Pro-Plus Software. For statistical analysis we used Spearman's coefficient. Differences were considered statistically significant if P≤0.05. RESULTS: the ossicular chain was involved in 65 cases. The incus was the most frequently affected bone, followed by the stapes and the malleus. When the Spearman's coefficient was employed considering ossicular chain change degree with patient's age by the time of surgery, perimatrix thickness and histological degree of inflammation, correlations were not established. CONCLUSION: Our findings indicate that ossicular chain changes are practically universal when a cholesteatoma is present. We didn't find correlations related with bone erosion and cholesteatoma's histological findings.
