ABSTRACT INTRODUCTION: Acquired middle ear cholesteatoma can be classified as primary or secondary. Although both can result in hearing loss, it is still controversial whether there is an association between the type of cholesteatoma and the degree of hearing loss. OBJECTIVE: To analyze the association between hearing loss and the type of acquired cholesteatoma, and the status of the ossicular chain. METHODS: This was a cross-sectional historical cohort study involving patients diagnosed with acquired cholesteatoma who were surgically treated. Air and bone conduction thresholds, air-bone gaps and the status of the ossicular chain were analyzed for both types of cholesteatoma. RESULTS: Eighty patients aged 5-57 were included in the study. Fifty-one patients had primary cholesteatoma and 29 had secondary cholesteatoma. Both types of cholesteatoma determined greater air-bone gaps at 0.5 kHz. Secondary cholesteatoma determined greater hearing loss in all analyzed frequencies and higher air conduction and air-bone gap means. CONCLUSION: There was association between hearing loss and the type of cholesteatoma. Secondary cholesteatoma resulted in greater hearing impairment.

Otite média (OM) é considerada doença potencialmente grave em razão dos riscos de complicações que podem ocorrer em sua evolução. OBJETIVO: Estabelecer a incidência anual de complicações intratemporais de OM e avaliar prospectivamente os pacientes por meio da análise dos aspectos epidemiológicos e clínicos. MÉTODO: Estudo de coorte contemporânea. Durante o período de um ano, os pacientes admitidos em um Hospital Universitário, com diagnóstico de OM e de complicação intratemporal (CIT) de OM foram incluídos no estudo. Os dados avaliados foram: idade, sexo, tipo de complicação intratemporal, tratamento e desfecho clínico. A incidência geral das complicações e de cada complicação foi determinada. RESULTADOS: 1.816 pacientes foram diagnosticados com OM. Em 592 (33%) indivíduos, o diagnóstico foi de otite média crônica; em 1224 (67%) o diagnóstico foi de otite média aguda. CIT de OM foi diagnosticada em 15 pacientes, perfazendo uma incidência anual de CIT 0,8%. Foram identificados 19 diagnósticos de CIT em 15 pacientes. Fístula labiríntica foi diagnosticada em sete (36,8%) indivíduos, mastoidite em cinco (26,3%), paralisia facial periférica em quatro (21,1%) e labirintite em três (15,8%). CONCLUSÃO: A incidência das complicações intratemporais permanece significativa quando comparada à de países desenvolvidos. A otite média crônica colesteatomatosa é a etiologia mais frequente das complicações intratemporais. A fístula labiríntica é a complicação intratemporal mais comum.Otitis media (OM) is considered a potentially severe disease due to the risk of complications. OBJECTIVE: To establish the annual incidence of intratemporal complications (ITC) resulting from OM and to prospectively assess patients for epidemiological and clinical factors. METHOD: This prospective cohort study included patients admitted during one year at a university hospital diagnosed with intratemporal complications of OM. Patients were analyzed for age, gender, type of intratemporal complication, treatment, and clinical outcome. The overall incidence of complications and the specific incidence rates of each type of complication were determined. RESULTS: 1,816 patients were diagnosed with OM; 592 (33%) had chronic OM; 1224 (67%) had acute OM. Fifteen patients were diagnosed with OM ITC, adding up to an annual incidence of 0.8%. Nineteen diagnoses of ITC were made in 15 patients. Seven (36.8%) patients were diagnosed with labyrinthine fistula, five (26.3%) with mastoiditis, four (21.1%) with peripheral facial palsy, and three (15.8%) with labyrinthitis. CONCLUSION: The incidence of intratemporal complications remains significant when compared to the rates seen in developed countries. Chronic cholesteatomatous otitis media is the most frequent etiology of intratemporal complications. Labyrinthine fistula is the most common intratemporal complication.

Atresia óssea e otite média crônica são os principais grupos de beneficiários com implantes do ouvido médio. Cirurgia de atresia é tecnicamente complexo, tem muitas complicações e resultados funcionais pobres. Os aparelhos auditivos osseointegrados são uma alternativa. Eles fornecem um ganho funcional muito bom, mas tem muitos problemas de pele e osseointegração. Na otite média crônica, ossiculoplastias resolveram parcialmente o problema de audição. Infelizmente, em alguns casos de otites média e cavidades abertas, equipamentos com aparelhos auditivos convencionais são difíceis e muitas vezes insatisfatórios. OBJETIVO: Determinar a utilidade de um implante do ouvido médio. Desenho de estudo longitudinal. MÉTODOS: Vibrant-Soundbrigde foi implantado em oito pacientes com perda auditiva mista grave. Quatro apresentavam otite média crônica e quatro apresentavam atresia unilateral. A colocação do estimulador (FMT ou Floating Mass Transducer) foi em cinco pacientes na janela redonda, dois no estribo e um na janela oval. RESULTADOS: Ganho funcional foi de 35 dB, 40 dB, 48,7 dB e 50 dB para as frequências de 500, 1000, 2000 e 4000 Hz, respectivamente. CONCLUSÃO: Vibrant-Soundbrigde é uma excelente opção no restabelecimento da audição em perda auditiva mista grave e profunda. Ele fornece um excelente ganho funcional em doenças de difícil tratamento com equipamentos convencionais.Osseous atresia and chronic otitis media are diseases benefit with middle ear implants. Surgery for atresia is technically complicated, has significant number of complications and functional results are often poor. The osseointegrated hearing aids are an alternative. They provide a very good functional gain, but have many problems with the skin and osseointegration. In chronic otitis media, the ossiculoplasty solved partially the hearing problem. Unfortunately in some cases of otitis media and in open cavities fitted with conventional hearing aids the gain is unsatisfactory. AIM: To determine the usefulness of an active middle ear implant. MATERIAL AND METHOD: Longitudinal Study. Vibrant- Soundbrigde was implanted in eight patients with severe mixed hearing loss. Four patients had chronic otitis media and four had unilateral atresia. The placement of the stimulator (FMT or Floating Mass Transducer) was in five patients on round window, two in stapes and one in the oval window. RESULTS: Functional gain was 35 dB, 40 dB, 48.7 dB and 50 dB for the frequencies 500, 1000, 2000 and 4000 Hz, respectively. CONCLUSION: Vibrant-Soundbrigde is an excellent option in hearing recovery in severe and profound mixed hearing loss. It also provides an excellent functional gain in diseases difficult to treat with conventional hearing aids.

Many studies have shown the consequent gustatory alteration caused by ear surgeries. However, few have reported this alteration in patients with chronic otitis media (COM), prior to surgical treatment. AIM: to identify gustatory alterations due to chorda tympani nerve involvement in patients with COM without prior surgery. METHODS: Clinical essay, with tests based on "taste strips" with different concentrations of salt, sweet, bitter, and sour, was performed in 45 patients with unilateral cholesteatomatous or suppurated COM not previously submitted to otological surgery, using the disease-free ear on the contralateral side as control. The score ranged between 0 and 16. RESULTS: A total of 25 patients presented cholesteatoma and 20 had non-cholesteatomatous disease. The mean score was 6.65 for the affected side and 9.93 for the half of the tongue on the side of the healthy ear (pMuitos estudos mostraram a consequente alteração do paladar após cirurgia otológica. Entretanto, poucos reportaram essa alteração como uma queixa de pacientes com otite média crônica (OMC) previamente à cirurgia. OBJETIVO: Avaliar alterações na função gustatória na área inervada pelo nervo corda do tímpano em pacientes com OMC ainda não submetidos à cirurgia. MATERIAL E MÉTODOS: O ensaio clínico, com teste gustatório baseado em "tiras gustativas" com diferentes concentrações de sal, doce, amargo e azedo, foi realizado em 45 pacientes com OMC colesteatomatosa e não-colesteatomatosa unilateral, nunca antes submetidos à cirurgia otológica, utilizando a metade da língua do lado livre de doença otológica como controle. As notas variavam de 0 a 16. RESULTADOS: 25 pacientes apresentavam colesteatoma e o restante OMC não-colesteatomatosa. A pontuação média foi de 6,65 para o lado afetado e 9,93 para a metade da língua do lado sadio (p
