Evaluation of the prevalence and characteristics of tinnitus in a Brazilian series of sleep bruxism patients. In this descriptive study, 100 patients (80 women and 20 men) were selected through the self-report of grinding teeth during sleep, confirmed by room mate or family member. They were evaluated according to a systematized approach: a questionnaire for orofacial pain and the Portuguese version of the Research Diagnostic Criteria for Temporomandibular Disorders. The patients were divided into two groups: group A, 54 patients with complaint of tinnitus and group B, 46 patients without tinnitus complaint. The mean age was 37.85 (13-66 years) and 34.02 years (20-59 years), respectively, for groups A and B (P = 0.1164). There was statistically significant difference between the two groups, with higher prevalence for the group A, in relation to: presence of chronic facial pain (P = 0.0007); number of areas painful to palpation in the masticatory and cervical muscles (P = 0.0032); myofascial pain in the masticatory muscles (P = 0.0003); absence of teeth without prosthetic replacement (P = 0.0145) and indices of depression (P = 0.0234). Structural alterations of the TMJ, like disc displacement and vertical dimension loss did not differ for the two groups. Tinnitus frequency was higher in patients with sleep bruxism and chronic facial pain. Myofascial pain, number of areas painful to palpation in the masticatory and cervical muscles, higher levels of depression and tooth absence without prosthetic replacement were more frequent in the group with tinnitus.

Objetivo Investigar a associação entre disfunção temporomandibular (DTM) dolorosa, auto-relato de zumbido e níveis de depressão. Método A amostra foi composta por 224 indivíduos com idades de 18 a 76 anos. O Research Diagnostic Criteria for Temporomandibular Disorders , eixo I, foi usado para classificar a DTM e o eixo II para obtenção do auto-relato de zumbido e dos níveis de depressão. Para a análise dos dados, foi aplicado o teste odds ratio (OR) com intervalo de confiança (IC) de 95%. Resultado Somente a presença de DTM dolorosa estava significativamente associada aos níveis de depressão moderado/severo (OR=9,3, 95%; IC: 3,44-25,11). A presença concomitante de DTM dolorosa e auto-relato de zumbido aumentaram a magnitude da associação com os níveis de depressão moderado/severo (OR=16,3; 95% IC: 6,58-40,51). Conclusão Disfunção temporomandibular dolorosa, altos níveis de depressão e auto-relato de zumbido estão fortemente associados. Entretanto, o desenho do estudo não permite estabelecer uma relação causal entre essas três entidades.

INTRODUÇÃO: Na área ocupacional, a maior parte dos trabalhos enfatiza os efeitos do ruído sobre a audição dos trabalhadores, menosprezando o efeito dos defensivos agrícolas na audição. OBJETIVO: Avaliar e correlacionar a audição e o zumbido de indivíduos expostos concomitantemente à ruído e organofosforado no ambiente de trabalho e mensurar o impacto do zumbido na qualidade de vida destes trabalhadores. MÉTODO: Trata-se de um estudo clínico, retrospectivo. Foram avaliados 82 dessinsetizadores expostos a ruído e organosfosforado atuantes no combate a dengue de uma autarquia estadual paulista. Todos os trabalhadores realizaram audiometria tonal liminar e responderam a versão traduzida do questionário THI (Tinnitus Handicap Inventory). RESULTADOS: 28,05% dos funcionários relataram que apresentam ou já apresentaram o zumbido e nos trabalhadores com zumbido há uma incidência maior de audiometria alterada. A média dos limiares auditivos nos trabalhadores com zumbido nas frequências entre 4 e 8 kHz encontravam-se mais elevados em relação aos demais, sendo a frequência de 4 kHz a mais comprometida. A pontuação do THI variou de 0 a 84, com média de 13,1. Foi observado que 12 (52,17%) sujeitos apresentaram escores do THI compatíveis com handicap discreto. CONCLUSÃO: Há uma incidência maior de audiometria alterada nos trabalhadores com zumbido, sendo que o impacto do zumbido na qualidade de vida destes trabalhadores foi discreto. As médias dos limiares tonais e o zumbido correlacionaram-se de forma fraca positiva.

Objectives: We performed a prospective clinical study of the cochleovestibular symptoms and the risk cofactors and characteristics of hearing loss in patients with type 1 diabetes.Methods: Group I consisted of 40 patients with type I diabetes, and group 2 consisted of 20 control subjects without diabetes. All participants answered a questionnaire, and their medical records were reviewed. They also were submitted to otorhinolaryngological examinations and to auditory tests (pure tone audiometry and acoustic immitance and auditory brain stem response [ABR] tests).Results: Dyslipidemia, hypertension, retinopathy, and diabetic neuropathy were not frequent in the patients of group 1, but incipient nephropathy was present in 47.5% of them. The most frequent cochleovestibular symptoms were tinnitus and hearing loss. Sensorineural hearing loss was found in 4 patients of group I and was predominantly bilateral, symmetric, and affecting the high frequencies, coexisting with normal vocal discrimination. These patients had a longer time from diabetes diagnosis and had poor glycemia control. A delay of ABR interpeak latency I-III was observed in 11.25% of the group I ears. All patients of group 2 presented normal audiograms and ABR tests.Conclusions: In group 1, the most frequent cochleovestibular symptoms were tinnitus and hearing loss. The sensorineural hearing loss was mild, symmetric, and predominantly high-frequency. A delay of ABR interpeak latencies was detected in the patients of group I who had normal audiometric thresholds.

O estudo verificou a associação entre perda auditiva induzida por ruído (PAIR) e queixa de zumbido em trabalhadores expostos ao ruído ocupacional. Foram entrevistados e avaliados trabalhadores com histórico de exposição ao ruído ocupacional atendidos em dois ambulatórios de audiologia. Estudou-se a existência de associação entre PAIR e ocorrência de zumbido por intermédio do ajuste de modelo de regressão logística, tendo como variável dependente o zumbido e como variável independente a PAIR, classificada em seis graus, controlada pelas co-variáveis idade e tempo de exposição ao ruído. Os dados foram coletados entre abril e outubro de 2003, na Cidade de Bauru, Estado de São Paulo, Brasil, contemplando 284 trabalhadores. Estimou-se que a prevalência de zumbido aumenta de acordo com a evolução do dano auditivo, controlado para a idade e tempo de exposição ao ruído. Os achados justificam o investimento em programas de conservação auditiva particularmente voltados para o controle da emissão de ruídos na fonte e para a intervenção na evolução das perdas auditivas geradas pela exposição ao ruído visando à manutenção da saúde auditiva e à diminuição dos sintomas associados.

Hearing loss and tinnitus impact the lives of workers in every instance of their lives. Aim: this paper aims to investigate the existence of a dose-response relationship between hearing loss and tinnitus by determining whether higher levels of hearing loss can be associated with increased tinnitus-related discomfort. Materials and method: this cross-sectional case study assessed 284 workers exposed to occupational noise through pure tone audiometry. Test results were categorized as defined by Merluzzi. Individuals complaining of tinnitus answered the adapted and validated Brazilian Portuguese version of the Tinnitus Handicap Inventory. A generalized linear model was adjusted for binomial data to test the interaction between these factors. Results: over 60% of the ears analyzed had hearing loss, while more than 46% of them had tinnitus. Tinnitus prevalence and risk rates increased as pure tone audiometry results got worse. The association between both, considering all hearing loss degrees, was statistically significant. Conclusion: the results point to a statistical association between hearing loss and tinnitus; the greater the hearing loss, the greater the discomfort introduced by tinnitus. 2009 © Revista Brasileira de Otorrinolaringologia.

Because nonespecific symptoms and signs are associated with others well-established in the temporomandibular disorders, it is difficult for the clinician to decide what symptoms and signs should be considered during the diagnosis and the treatment plan. Therefore, the aim of this literature review was to evaluate the prevalence of aural symptoms (otalgias, tinnitus, dizziness and deafness) in patients with orofacial pain. Although several hypotheses have been proposed to explain the association between aural symptoms and temporomandibular disorders, the results of the previous studies differed in magnitude. For this reason, it is difficult to establish the prevalence of these aural symptoms concomitantly with temporomandibular disorders. Moreover, such relationship does not necessarily imply a cause-effect relationship. Because of the diagnosis complexity, different treatments must be considered, so the nonespecific symptoms of temporomandibular disorders can be effectively controlled as well. It is crucial for the the clinician to be aware of the possible etiology of aural symptoms, so he should determine if such symptoms may be associated with temporomandibular disorders and thus include them in the treatment.

Introduction: A variety of hypotheses have been proposed to explain the association between temporomandibular disorders and hearing symptoms, including the many anatomical and/or neurological ways, as of a muscle or joint dysfunction, can cause such symptoms. Objective: The purpose of this study is to discuss, through a systematic review of literature, the interrelation between hearing symptoms and temporomandibular disorders. Material and Methods: We consulted the Medline/PubMed, ISI and Scielo in the period 1918 to 2008. The terms related to the research were: “temporomandibular disorders”, “signs and symptoms of temporomandibular disorders”, “otologic symptoms” and “aural symptoms”, where 19 papers were included using the pre-selected criteria for the manufacture of a meta-analysis. Results: According to the findings, the hearing symptoms most often associated with temporomandibular disorders were otalgia and tinnitus, followed by vertigo and hearing loss, respectively. Conclusions: It’s clear the correlation between hearing symptoms and temporomandibular disorders, however there is a need clinical and scientific research more complex to prove the specific cause-effect relationships between them.

Costen’s syndrome is defined as a set of auditory signs and symptoms in patients with TMD. It is characterized by ear fullness, hearing loss, tinnitus, ear pain and vertigo with nystagmus.It has predilection for females and fourth decade of life. The multidisciplinary monitoring of these patients is imperative in its recognition and the establishment of effective therapy. In this paper we report a case of Costen’s Syndrome patient whose treatment consisted of advice on the etiology of the disorder and weekly sessions of acupuncture. The clinical features that led to the diagnosis and treatment plan, and the effectiveness of acupuncture as supportive therapy were also discussed.
