Brazilian Society of Otology task force - Otosclerosis: evaluation and treatment

Abstract Objectives: To review and provide evidence-based recommendations for the diagnosis and treatment of otosclerosis. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on otosclerosis were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: 1) Diagnosis - audiologic and radiologic; 2) Treatment - hearing AIDS, pharmacological therapy, stapes surgery, and implantable devices - bone-anchored devices, active middle ear implants, and Cochlear Implants (CI). Conclusions: The pathophysiology of otosclerosis has not yet been fully elucidated, but environmental factors and unidentified genes are likely to play a significant role in it. Women with otosclerosis are not at increased risk of worsening clinical condition due to the use of contraceptives or during pregnancy. Drug treatment has shown little benefit. If the patient does not want to undergo stapedotomy, the use of hearing aids is well indicated. Implantable systems should be indicated only in rare cases, and the CI should be indicated in cases of profound deafness.

Brazilian Society of Otology task force - Vestibular Schwannoma - evaluation and treatment

Abstract Objective: To review the literature on the diagnosis and treatment of vestibular schwannoma. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: (1) Diagnosis - audiologic, electrophysiologic tests, and imaging; (2) Treatment - wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. Conclusions: Decision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.

Task force Guideline of Brazilian Society of Otology - hearing loss in children - Part II - Treatment

Abstract Objectives: To provide an overview of the main evidence-based recommendations for the diagnosis of hearing loss in children and adolescents aged 0-18 years. Methods: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on childhood hearing loss were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. Results: The topics were divided into 2 parts: (1) treatment of sensorineural hearing loss: individual hearing aids, bilateral cochlear implants, cochlear implants in young children, unilateral hearing loss, and auditory neuropathy spectrum disorder; and (2) treatment of conductive/mixed hearing loss: external/middle ear malformations, ventilation tube insertion, and tympanoplasty in children. Conclusions: In children with hearing loss, in addition to speech therapy, Hearing AIDS (HAs) or implantable systems may be indicated. Even in children with profound hearing loss, both the use of HAs and behavioral assessments while using the device are important.

Is there a change in P300 evoked potential after 6 months in cochlear implant users?

Abstract Objective: There are few studies on long-latency auditory evoked potential (P300) in people with hearing loss who use a cochlear implant. Central auditory system evaluation with behavioral and electrophysiological tests is believed to help understand the neuroplasticity mechanisms involved in auditory functioning after cochlear implant surgery. This study investigated the electrophysiological processing of cortical level acoustic signals in a group of 21 adult individuals with postlingual bilateral severe-to-profound hearing loss who were submitted to cochlear implant surgery. Methods: Data were collected in three phases: pre-cochlear implant surgery, at cochlear implant activation, and 6 months after surgery. P300 measures were also registered during all phases. Tone-burst and speech stimuli were used to elicit P300 and were presented in free field. Results: Mean P3 component latency with tone-burst and speech stimuli were 352.9 and 321.9 ms in the pre-cochlear implant phase, 364.9 and 368.7 ms in the activation phase, 336.2 and 343.6 ms 6 months after the surgery. The P3 component mean latency values using tone-burst at activation were significantly different from those 6 months after cochlear implant. They were also significantly different using speech, between pre-cochlear implant and activation phases. Lower P3 component latency occurred 6 months after cochlear implant activation with tone-burst and pre-cochlear implant with speech stimulus. There was a weak correlation between mean P3 component latency with speech stimulus and time of hearing loss. There was no difference in amplitude between phases or in the comparison with the other variables. Conclusion: There were changes in P3 component latency during the period assessed, for both speech and pure-tone stimuli, with increased latency in the activation phase and similar lower results in the two other phases, Pre-CI and 6 months after CI use. Mean amplitude measures did not vary in the three phases.

Symptom assessment after nasal irrigation with xylitol in the postoperative period of endonasal endoscopic surgery / Avaliação dos sintomas após irrigação nasal com xilitol no período pós-operatório de cirurgias endoscópicas endonasais

Abstract Introduction: Chronic rhinosinusitis is an inflammatory condition of the nasal cavity and the paranasal sinuses that requires multifactorial treatment. Xylitol can be employed with nasal irrigation and can provide better control of the disease. Objective: To evaluate the association between the effects of nasal lavage with saline solution compared to nasal lavage with a xylitol solution. Methods: Fifty-two patients, divided into two groups (n = 26 in the "Xylitol" group and n = 26 in the "Saline solution" group) answered questionnaires validated in Portuguese (NOSE and SNOT-22) about their nasal symptoms and general symptoms, before and after endonasal endoscopic surgery and after a period of 30 days of nasal irrigation. Results: The "Xylitol" group showed significant improvement in pain relief and nasal symptom reduction after surgery and nasal irrigation with xylitol solution (p < 0.001). The "Saline solution" group also showed symptom improvement, but on a smaller scale. Conclusion: This study suggests that the xylitol solution can be useful in the postoperative period after endonasal endoscopic surgery, because it leads to a greater reduction in nasal symptoms.

Resumo Introdução: Rinossinusite crônica é um quadro de inflamação da cavidade nasal e dos seios paranasais que necessita de tratamento multifatorial. O xilitol pode ser associado às irrigações nasais e pode prover melhor controle da doença. Objetivo: Avaliar a relação entre os efeitos da lavagem nasal com solução fisiológica em comparação à lavagem nasal com solução de xilitol. Método: Divididos em dois grupos (n = 26 no grupo Xilitol e n = 26 no grupo Soro), 52 pacientes responderam à questionários validados em língua portuguesa (NOSE e SNOT-22) sobre seus sintomas nasais e sintomas gerais, antes e depois de cirurgia endoscópica endonasal e após um período de 30 dias de irrigação nasal. Resultados: O grupo Xilitol apresentou melhoria significativa dos sintomas de dor e sintomas nasais após a cirurgia e a irrigação nasal com solução de xilitol (p < 0,001). O grupo Soro também apresentou melhoria dos sintomas, porém em menor escala. Conclusão: Este estudo sugere que a solução de xilitol pode ser usada no período pós-operatório de cirurgia endoscópica endonasal por levar a uma maior redução nos sintomas nasais.

Foreign Body in Jugal Mucosa

Introduction Foreign body in the oral cavity may be asymptomatic for long time and only sometimes it can lead to a typical granulomatous foreign body reaction. Some patients may complain of oral pain and present signs of inflammation with purulent discharge. A granuloma is a distinct, compact microscopic structure composed of epithelioid-shaped macrophages typically surrounded by a rim of lymphocytes and filled with fibroblasts and collagen. Nowadays, the increase of cosmetic invasive procedures such as injection of prosthetic materials in lips and cheeks may lead to unusual forms of inflammatory granulomas. Objectives Describe an unusual presentation of a foreign body reaction in the buccal mucosa due to previous injection of cosmetic agent. Resumed Report A 74-year-old woman was referred to the Department of Otorhinolaryngology, Head and Neck Surgery to investigate the presence of multiple painless, bilateral nodules in the buccal mucosa, with progressive growth observed during the previous 2months. The histologic results showed a foreign body inflammatory reaction. Conclusion Oral granulomatosis lesions represent a challenging diagnosis for clinicians and a biopsy may be necessary. Patients may feel ashamed to report previous aesthetic procedures, and the clinicians must have a proactive approach.(AU)

Achados otorrinolaringológicos em um grupo de pacientes com doenças reumatológicas / Otorhinolaryngological findings in a group of patients with rheumatic diseases

Introdução: As manifestações otorrinolaringológicas de doenças reumáticas representam um grande desafio não só ao médico generalista, mas também ao otorrinolaringologista e ao reumatologista. Frequentemente representam manifestações iniciais de uma desordem autoimune que exige um tratamento imunossupressor imediato e agressivo. Sintomas auditivos, nasais, laríngeos e oculares podem ser a primeira manifestação de doenças reumáticas, e sua correta avaliação auxilia o médico a identificar sinais de atividade da doença. O objetivo deste trabalho foi identificar as manifestações otorrinolaringológicas em pacientes com doenças reumáticas em um hospital de alta complexidade, no que se refere a facilitar diagnóstico e tratamento precoces. Métodos: Foram realizadas avaliações clínicas e otorrinolaringológicas completas em pacientes selecionados no ambulatório de reumatologia, no segundo semestre do ano de 2010, de forma padronizada e com utilização de um formulário de preenchimento normatizado. Resultados: No grupo estudado, pacientes com LES apresentaram predominantemente manifestações laríngeas, enquanto pacientes com síndrome de Sjögren apresentaram predomínio das manifestações otológicas (100% dos casos). As alterações de exames audiométricos são encontradas em 53% dos casos portadores de GW, 80% de PR, 33% de LES e 50% de SCS. Quanto às alterações nasais, estas foram encontradas de forma prevalente em todas as patologias, principalmente a síndrome de Churg-Strauss. Discussão e conclusão: Este estudo demonstrou que a maioria dos pacientes em seguimento em nosso serviço apresenta os sinais e sintomas otorrinolaringológicos comumente relacionados em ...

Introduction: Otorhinolaryngological manifestations of rheumatologic diseases represent a great challenge not only to the generalistphysician but also to the ENT doctor andrheumatologist. They often represent early manifestations of an autoimmune disorder which requires prompt and aggressive immunosuppressive treatment. Auditory, nasal, laryngeal and eye symptoms can be the first manifestation of rheumatic diseases and their proper assessment helps the doctor to identify signs of disease activity. The objective of this study is to identify the ENT manifestations in patients with rheumatic diseases in a high complexity hospital, regarding facilitating an early diagnosis and treatment. Methods: We performed clinical and complete otorhinolaryngological evaluations in patients selected from the outpatient rheumatology in a standardized manner by the use of a standardized form filling during the secondhalf of 2010. Results: In the study group, systemic lupus erythematosus (SLE) patients had predominantly laryngeal manifestations, while patients with Sjögren's syndrome showed a higher prevalence of otologic manifestations. Changes in audiometric tests were found in 53% of Wegener's granulomatosis (WG) patients, 80% of relapsing polychondritis (RP), 33% of systemic lupus erythematosus (SLE) and 50% of Churg-Strauss syndrome (SCS). Regarding nasal alterations, these were found so prevalent in all conditions, especially Churg-Strauss syndrome. Discussion and conclusion: This study demonstrated that most patients treated in our hospital has the ENT signs and symptoms commonly associated in previous studies on rheumatic diseases, but further studies with a larger number of patients must be made to establish such relations. .

Mixoma de osso maxilar: Diagnóstico e tratamento / Myxoma of the maxilla: Diagnosis and treatment

Introdução: Os mixomas odontogênicos são tumores benignos,raros, de origem mesenquimal, que acometem principalmentea mandíbula. Esses tumores apresentam um comportamentolocal agressivo e tendem a recorrer. Seus principais diagnósticosdiferenciais incluem os tumores queratocísticos, odontomas,ameloblastomas, entre outros. Por serem resistentes àquimioterapia ou radioterapia, devem ser tratados cirurgicamente,por curetagem da lesão para lesões menores ou cirurgia comexérese total e ressecção óssea, entretanto a primeira opção estárelacionada a altas taxas de recorrência (acima de 25%). Relatode caso: Apresentamos o caso de uma paciente do sexo feminino,de 31 anos, diagnosticada com um mixoma odontogênico centralem região de maxila, submetida à cirurgia de maxilectomia, comressecção da porção infraestrutural, com exérese total da lesão(margens livres) e colocação de prótese no transoperatório.

Implante coclear Digisonic SP® Binaural: acesso coronal tunelizado / Digisonic SP® Binaural cochlear implant: the coronal tunneled approach

O implante coclear é um grande avanço no tratamento da surdez. Há grandes evidências que a audição bilateral traz diversas vantagens ao ser humano e muito mais quando se trata de audição binaural. OBJETIVO: Este artigo tem por objetivo descrever o primeiro caso operado no Brasil, sendo o terceiro país das Américas (México e Colômbia) a realizar, com implante binaural Neurelec Digisonic SP® demonstrando a técnica cirúrgica. MÉTODO: Descrição da técnica cirúrgica. RESULTADOS: Ver técnica cirúrgica. Procedimento ocorreu sem intercorrências. DISCUSSÃO: O efeito "squelch", a somação binaural, a localização da fonte sonora e o efeito sombra da cabeça são umas das principais razões que justificam a superioridade da reabilitação binaural. O custo do tratamento deve ser levado em conta em políticas de saúde pública. CONCLUSÃO: Custo do implante coclear é um dos grandes limitadores da bilateralidade na reabilitação desse grupo de pacientes, porém, com essa tecnologia, é possível solucionar esse problema, expondo o paciente a poucos riscos, com o uso de uma técnica cirúrgica pouco invasiva.

Cochlear implants represent a significant breakthrough in the treatment of hearing loss. Evidence indicates bilateral hearing brings significant benefits to patients, particularly when binaural hearing is offered. OBJECTIVE: To describe the first case of implantation of a Digisonic SP® Binaural Neurelec device in Brazil (the third implant placed in the Americas, after Mexico and Colombia) and the chosen surgical approach. METHOD: Description of a surgical approach. RESULTS: The procedure was successfully completed. DISCUSSION: The squelch effect, binaural summation, location of the sound source, and the shadow effect of the head are listed among the reasons to explain the superiority of binaural rehabilitation. Cost of treatment must be considered in the development of public health policies. CONCLUSION: The cost of cochlear implants has been one of the main impediments to bilateral rehabilitation. The Digisonic SP® Binaural Neurelec device addresses this issue and exposes patients to less risk through a minimally invasive implantation procedure.
