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.

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.

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.

Abstract Introduction The role of elastin in tympanic retractions and chronic otitis media is not well established. Williams Syndrome (WS), a pathology related to a mutation in the elastin gene, could generate tympanic retractions. Objective To compare the prevalence of tympanic retractions among patients with WS and controls. Methods WS patients (n= 43 ears) and controls (n= 130 ears) were evaluated by digital otoscopic examination and the degree of tympanic membrane retraction was classified by 2 blinded experienced otolaryngologists. Results The agreement rate between the evaluators was 71.1% for pars tensa and 65% for pars flaccida retraction (p< 0.001). The pars tensa and pars flaccida retractions are present in patients with WS after an adjusted residue of respectively - 2.8 and - 2.6 (p= 0.011 and p= 0.022) compared with controls. Conclusions Tympanic membrane retractions are not more common in the WS group when compared with controls.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Resumo Introdução: A otoneurologia é uma área de conhecimento que tem se expandido muito rapidamente. O estudo do sistema vestibular tem avançado tanto que mesmo definições básicas, como o significado dos sintomas vestibulares, foram apenas recentemente padronizadas. Objetivo: Apresentar uma revisão dos principais assuntos da otoneurologia, inclusive conceitos, diagnóstico e tratamento da otoneurologia, definir a evidência científica atual para facilitar a tomada de decisões e demonstrar as áreas mais carentes de evidência para estimular novas pesquisas. Método: Este texto é fruto do I Fórum Brasileiro de Otoneurologia, que reuniu os principais pesquisadores brasileiros dessa área para uma revisão da literatura. Serão feitos três trabalhos de revisão a serem publicados. Este primeiro abordou as definições e as terapias, o segundo abordará as ferramentas diagnósticas e o terceiro definirá os principais diagnósticos. Cada autor fez um levantamento bibliográfico na base de dados da Lilacs, SciELO, Pubmed e Medline de um determinado assunto. O seu texto foi então submetido aos demais participantes do Fórum por 30 dias para análise. Um capítulo especial, da definição dos sintomas vestibulares, foi traduzido por serviço de tradução oficial e igualmente submetido às demais etapas do processo. Houve então uma reunião presencial em que todos os textos foram apresentados oralmente e houve uma discussão entre os participantes para a definição de um texto consensual para cada capítulo. Os textos consensuais foram então submetidos a uma revisão final por quatro professores de otoneurologia de três universidades brasileiras e, por fim, finalizado. A partir do texto completo, publicado no site da Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial, foi escrita esta versão-resumo como artigo de revisão. Resultado: O texto apresenta a tradução oficial para o português da definição dos sintomas vestibulares propostos pela Barany Society e agrupa as principais evidências científicas para cada um das principais terapias existentes para as doenças otoneurológicas. Conclusão: Este texto agrupou de forma racional os principais tópicos de conhecimento a respeito das definições e terapias da otoneurologia, permite ao leitor uma visão ampla da abordagem dos pacientes otoneurológicos baseada em evidências científicas e experiência nacional, que deverá auxiliá-lo na tomada de decisões clínicas, e mostra os assuntos mais carentes de evidência para estimular novos estudos.

Abstract Introduction: Neurotology is a rapidly expanding field of knowledge. The study of the vestibular system has advanced so much that even basic definitions, such as the meaning of vestibular symptoms, have only recently been standardized. Objective: To present a review of the main subjects of neurotology, including concepts, diagnosis and treatment of Neurotology, defining current scientific evidence to facilitate decision-making and to point out the most evidence-lacking areas to stimulate further new research. Methods: This text is the result of the I Brazilian Forum of Neurotology, which brought together the foremost Brazilian researchers in this area for a literature review. In all, there will be three review papers to be published. This first review will address definitions and therapies, the second one will address diagnostic tools, and the third will define the main diseases diagnoses. Each author performed a bibliographic search in the LILACS, SciELO, PubMed and MEDLINE databases on a given subject. The text was then submitted to the other Forum participants for a period of 30 days for analysis. A special chapter, on the definition of vestibular symptoms, was translated by an official translation service, and equally submitted to the other stages of the process. There was then a in-person meeting in which all the texts were orally presented, and there was a discussion among the participants to define a consensual text for each chapter. The consensual texts were then submitted to a final review by four professors of neurotology disciplines from three Brazilian universities and finally concluded. Based on the full text, available on the website of the Brazilian Association of Otorhinolaryngology and Cervical-Facial Surgery, this summary version was written as a review article. Result: The text presents the official translation into Portuguese of the definition of vestibular symptoms proposed by the Bárány Society and brings together the main scientific evidence for each of the main existing therapies for neurotological diseases. Conclusion: This text rationally grouped the main topics of knowledge regarding the definitions and therapies of Neurotology, allowing the reader a broad view of the approach of neurotological patients based on scientific evidence and national experience, which should assist them in clinical decision-making, and show the most evidence-lacking topics to stimulate further study.

Abstract Introduction The prevalence of tinnitus is higher in individuals with temporoman- dibular joint disorder (TMD) than in the general population. Magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) is the method of choice for investigation, and it has been hypothesized that speciﬁc MRI ﬁndings might be observed in TMD with comorbid tinnitus. Objective To comparatively describe MRI ﬁndings in patients with TMD with and without tinnitus, identifying the most common TMJ alterations and determining whether a correlation exists between severity of TMD and tinnitus. Methods A cross-sectional study of 53 adult patients with bilateral or unilateral TMD (30 with and 23 without tinnitus). The association between tinnitus and morphological aspects of TMD (changes in condylar morphology, articular eminence morphology, and disc morphology), disc displacement (with/without reduction), condylar translation, and intra-articular effusion was analyzed on MRI images. Results The mean patient age was 46.12 ± 16.1 years. Disc displacement was the most common ﬁnding in both groups (24 patients with tinnitus versus 15 without; p = 0.043). Only the frequency of disc displacement with reduction was signiﬁcantly different between groups. Conclusion Additional imaging techniques should be explored to detect speciﬁc aspects of the relationship between tinnitus and TMD.

Abstract: En | Text: En | PDF: En

Background Harboyan syndrome, defined as congenital corneal dystrophy associated with progressive sensorineural hearing loss, was first described by Harboyan in 1971. It is a hereditary disease manifested by eye lesions consistent with corneal endothelial dystrophy and progressive sensorineural hearing loss. There is bilateral symmetric progressive hearing loss, which may be either dominant or recessive. Objective To report a case of a patient with a diagnosis of Harboyan syndrome. Case Report A 25-year-old woman with profound bilateral sensorineural hearing loss, showing poor hearing performance while using a personal sound amplification device, underwent hearing rehabilitation with a cochlear implant. Conclusion Rehabilitation was imperative in this case. The cochlear implant has proven to be the best therapeutic option, providing the patient with a better quality of life.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

A técnica de acesso combinado (TAC) ao implante coclear (IC) é uma variação da técnica clássica de mastoidectomia e timpanotomia posterior (MPTA). A TAC combina um acesso transcanal à cocleostomia com uma timpanotomia posterior reduzida para a inserção dos eletrodos. OBJETIVO: Avaliar e comparar a segurança e efetividade em longo prazo alcançados com a TAC e MPTA em pacientes submetidos a IC em um centro brasileiro. Desenho científico: Estudo de série. MATERIAL E MÉTODO: Pacientes submetidos a IC usando TAC e MPTA foram acompanhados em um estudo de coorte. Os desfechos avaliados foram complicações, avaliação audiométrica e radiológica pós-operatórias. RESULTADOS: Quarenta e quatro pacientes foram implantados usando a TAC e 31 usando MPTA. Não houve casos de paralisia facial, mastoidite, colesteatoma ou fístula após 3,4±1,0 anos. A avaliação radiológica da posição dos eletrodos a mediana de eletrodos fora da cóclea foi de 0 no grupo TAC e de 3 no MPTA (p < 0,001). Não houve diferença entre os grupos em termos de desempenho audiológico no pós-operatório. CONCLUSÃO: A cocleostomia via transcanal combinada com uma timpanotomia posterior reduzida é um acesso alternativo ao IC que demonstrou segurança e menor migração de eletrodos em longo prazo. Esses achados encorajam o uso da via transcanal para a cocleostomia como uma opção alternativa de acesso ao IC.

The combined approach technique (CAT) is a variation of the classical the mastoidectomy-posterior tympanotomy technique (MPTA) that combines a transcanal approach to cochleostomy with a reduced posterior tympanotomy for insertion of electrodes. AIM: To compare and evaluate long-term safety and effectiveness outcomes obtained with the CAT and with MPTA approach in patients submitted to cochlear implant (CI) surgery. Design: series study. METHODS: Patients who underwent CI using CAT or MPTA at a Brazilian center were followed in a cohort study. Main outcomes were complications,audiometric performance and radiological evaluation of electrode position. RESULTS: Fourty-four patients were implanted using CAT and 31 MPTA. There were no cases of facial nerve paralysis, mastoiditis, cholesteatoma or cerebrospinal fluid leaks after 3.4±1.0 years. Radiological evaluation of electrode position revealed that the median number of electrodes outside the cochlea was 0 in CAT and 3 in MPTA groups (p < 0.001). There were no differences between both surgical approaches in terms of mean pure-tone thresholds with CI at all frequencies. CONCLUSION: Long-term follow-up data showed that the transcanal route to cochleostomy, combined with a reduced posterior tympanotomy, is a safe alternative approach in cochlear implant surgery, with no related major complications and fewer cases of electrode migration when compared with the MPTA. These findings encourage the use of the transcanal route to cochleostomy as an alternative approach option.

A utriculostomia é uma nova alternativa cirúrgica para a doença de Ménière. A hipótese cirúrgica desse procedimento é a de que o desfecho de uma lesão do utrículo por eletrocauterização não interfere na função coclear. Contudo, a hipótese de que essa abordagem do utrículo preserva a audição ainda não foi comprovada. OBJETIVO: Determinar se ocorrem mudanças nos potenciais elétricos evocados na cóclea e no nervo auditivo antes, durante e 1 mês após o procedimento cirúrgico no utrículo em modelo animal. MATERIAIS E MÉTODOS: Estudo experimental: Oito ovelhas foram submetidas à lesão do utrículo por eletrocauterização e sua função coclear foi avaliada por meio de eletrococleografia, registrando-se os potenciais elétricos evocados nos períodos pré-operatório, pós-operatório imediato e pós-operatório de médio prazo. Os resultados foram analisados estatisticamente. RESULTADOS: Não houve variação estatisticamente significativa na amplitude (p = 0,099) e na latência (p = 0,591) antes e 1 mês após o procedimento cirúrgico. Houve alteração estatisticamente significativa na razão entre potencial de somação/potencial de ação (p = 0,0122), representando uma perda calculada de 11,8 dB. CONCLUSÃO: A intervenção realizada no utrículo neste estudo permite concluir que, tendo em conta respostas eletrofisiológicas deficientes observadas durante e 1 mês após o procedimento cirúrgico, houve preservação da audição nas ovelhas operadas.

Utriculostomy is a new surgical alternative for Ménière's disease. The basis of this procedure is that the outcome of an electrocautery-induced utricular trauma does not affect cochlear function. However, a demonstration of the hypothesis that this approach to the utricle would preserve hearing is still pending. OBJECTIVE: To determine whether any changes would occur in the electrical potentials evoked in the cochlea and auditory nerve before, during, and 1 month after a surgical procedure in the utricule in an animal model. MATERIALS AND METHODS: An experimental study. Eight sheep underwent electrocautery-induced utricular trauma, and their cochlear function was assessed by electrocochleography - recording of electrical evoked potentials, in the preoperative, immediate postoperative and medium-term postoperative periods. The results were analyzed statistically. RESULTS: There were no statistically significant variations in amplitude (p = 0.099) and latency (p = 0.591) before and 1 month after the surgical procedure. There was a statistically significant change in the summation of the potential/action potential area ratio (p = 0.0122), a calculated loss of 11.8 dB. CONCLUSION: The intervention performed in this study enabled us to conclude that, taking into account the impaired electrophysiological responses observed during and 1 month after the surgical procedure, hearing was preserved in the operated sheep.

INTRODUÇÃO: As cirurgias dos shunts endolinfáticos empregadas para o tratamento da vertigem na doença de Ménière incapacitante permanece um tópico controverso. Portmann, em 1926, foi o primeiro a executar a cirurgia, incisando o saco endolinfático com o objetivo de diminuir a pressão endolinfática da orelha interna. Planejadas para criar uma fístula que conecte o espaço endo e perilinfático, as saculotomias foram descritas por Fick em 1964, por Cody em 1969 e por Schuknecht (cocleossaculotomia) em 1982, entretanto foram paulatinamente abandonadas devido à alta incidência de perda auditiva. Uma nova e promissora opção cirúrgica dos shunts, em caráter experimental, é a utriculostomia, realizada por Lavinsky em 1999. OBJETIVO: Realizar uma revisão da literatura sobre as principais técnicas cirúrgicas dos shunts endolinfáticos empregados no tratamento da doença de Ménière, seus resultados e o que há de avanços no entendimento desses procedimentos. MÉTODO: Com base nos dados da literatura, são discutidas as principais técnicas cirúrgicas dos shunts endolinfáticos e sua racionalidade no tratamento da doença de Ménière incapacitante. CONCLUSÃO: Existe muita controvérsia sobre a efetividade dos procedimentos cirúrgicos dos shunts endolinfáticos para o tratamento da doença de Ménière incapacitante, e muitos deles causam danos à orelha interna. A cirurgia experimental utriculostomia, portanto, parece-nos uma opção promissora. Futuras pesquisas poderão fornecer a resposta para essa questão.

INTRODUCTION: The surgerys of the endolymphatic shunt are employed in the treatment of the vertigo of Meniere disease disabling, remains a controversial topic. Portmann in 1926, was the first to perform the surgery, incising the endolymphatic sac aimming the decrease of the endolymphatic pressure of the inner ear. Planned to create a fistula that connects the endo and perilymphatic space, the sacculotomy were described by Fick in 1964, by Cody in 1969 e by Schuknecht (cochleosacculotomy) in 1982, however they were gradually abandoned because of the high incidence of hearing loss. A new and promising surgery option of shunt, still experimental is utriculostomy, performed by Lavinsky in 1999. OBJECTIVE: Make a review of literature about the main surgical techniques of endolymphatic shunt, used in the treatment of Meniere disease, its results and the advance in the understanding of these procedures. METHODS: Based on the literature data, the main surgical techniques of endolymphatic shunt are discussed and its rationality in the treatment of Meniere's disabling disease. CONCLUSION: There are a lot of controversy over the effectiveness of surgical procedures of endolymphatic shunt for the treatment of Meniere's disabling disease, and a lot of them damage the inner ear. The experimental surgery of utriculostomy, so it seems, a promising option. Future research can give an answer to this matter.

OBJETIVO: O tratamento do edema macular difuso diabético atualmente é insatisfatório. O objetivo deste ensaio clínico randomizado duplo cego foi comparar, através de avaliação morfofuncional, o tratamento do edema macular difuso diabético com triancinolona intravítrea ou laser em grade em pacientes com DM tipo 2. MÉTODOS: Quatorze pacientes (21 olhos) com edema macular difuso clinicamente significativo, sem tratamento prévio e com espessura macular >250 µm à tomografia de coerência óptica (OCT) foram randomizados para tratamento com laser ou injeção intravítrea de acetato de triancinolona. Nos tempos 0, 1, 3 e 6 meses foram realizados OCT, biomicroscopia, fundoscopia, angiografia fluoresceínica, tonometria, escotometria, acuidade visual e de contraste. RESULTADOS: Na fase pré-tratamento, os grupos Laser (n=9) e Triancinolona (n=12) não diferiram na espessura retiniana, escotometria, acuidade visual e de contraste. No grupo Triancinolona houve redução da espessura macular após 1 mês (424,1 ± 19,9 µm vs. 358,4 ± 18,2 µm; P=0,04) com retorno aos valores iniciais a partir do mês 3 (P=0,02). Não houve modificação significativa na escotometria macular, acuidade visual e de contraste. Não ocorreram efeitos colaterais nos tratamentos. CONCLUSÃO: Durante o estudo observou-se diminuição da espessura macular no grupo tratado com triancinolona, principalmente no primeiro mês de tratamento. Aos 3 e 6 meses de tratamento não houve diferença. A espessura macular não modificou durante o estudo no grupo tratado com laser. Nesta amostra estudada não foi possível demonstrar diferenças relacionadas à escotometria e acuidade visual entre os dois grupos.

PURPOSE: Treatment of diffuse macular edema in diabetes mellitus is currently unsatisfactory. The purpose of this double blind randomized clinical trial was to compare the treatment of diffuse diabetic macular edema with intravitreal triamcinolone or laser in type 2 diabetes mellitus patients using a morphofunctional assessment. METHODS: Fourteen patients (21 eyes) with clinically significant diffuse macular-edema, previously untreated and with a macular thickness >250 µm at optical coherence tomography were randomized for treatment with laser or intravitreal injection of triamcinolone acetate. Optical coherence tomography, biomicroscopy, fundoscopy, fluorescein angiography, tonometry, scotometry, visual and contrast acuities were performed at 0, 1, 3 and 6 months. RESULTS: At pre-treatment stage, Laser (n=9) and Triamcinolone (n=12) groups did not differ regarding retinal thickness, visual and contrast acuities. In Triamcinolone group macular thickness decreased after 1 month (424.1 ± 19.9 µm to 358.4 ± 18.2 µm; p=0.04) and started to return to the initial values in the 3rd month (p=0.02). No changes occurred in macular scotometry and visual and contrast acuities. No side effects were observed with both treatments. CONCLUSION: During the study macular thickness diminished in the triamcinolone group, especially in the first month of treatment. At 3 and 6 months there was no difference. Macular thickness did not change during the study in the laser group. In the study sample it was not possible to demonstrate differences relates to visual acuity and scotometry between the two groups. CLINICALTRIALS.GOV IDENTIFIER: NCT00668239

Resultados prévios apontam para uma ótima correlação entre a morfologia e as dimensões das estruturas anatômicas de ovelhas e seres humanos. OBJETIVO: Analisar e descrever a histologia das estruturas que compõem o osso temporal do ovino. MATERIAL E MÉTODO: Um total de 307 lâminas obtidas a partir de secções verticais e horizontais do osso temporal de oito ovelhas foi analisado. As estruturas foram caracterizadas como semelhantes ou não semelhantes às do ser humano, com base na celularidade e na arquitetura histológica das estruturas. DESENHO CIENTÍFICO: Experimental. RESULTADOS: Constatou-se semelhança quanto ao tipo de epitélio, componente ósseo, espaços da fenda auditiva e arquitetura, além da semelhança, em nível histológico, tanto dos componentes celulares como das estruturas contíguas ao ouvido. As principais diferenças foram a presença da bula anatômica, o fato de a mastoide não se encontrar aerada e o hipotímpano, que se abre inferiormente para a bula. CONCLUSÃO: A partir dessas observações, é possível concluir que a ovelha é uma opção favorável para a experimentação em cirurgia otológica.

Previous studies suggest that there is an excellent correlation between the morphology and dimensions of ear structures in sheep and human beings. AIM: To analyze and describe the histology of structures inside the temporal bone in sheep. MATERIAL AND METHODS: A total of 307 slides obtained from vertical and horizontal sections of the temporal bone of eight sheep were analyzed. Structures were classified as similar or not similar to human structures, based on cellularity and histological architecture parameters. STUDY DESIGN: Experimental. RESULTS: The study revealed similarities between sheep and humans in terms of type of epithelium, bone component, spaces in the auditory meatus, in addition to a marked histological resemblance of cellularity and that of the structures surrounding the ear. The main differences observed were the presence of an anatomic bulla, the absence of aeration in the mastoid and the inferior opening of the hypotympanum into the bulla in sheep. CONCLUSION: Based on these observations, it is possible to conclude that sheep represent an adequate option for training and research in otologic surgery.

Este estudo tem como objetivo descrever uma técnica cirúrgica alternativa à inserção do tubo de ventilação na membrana timpânica: a miringotomia por radiofrequência isolada e associada à mitomicina C. OBJETIVO: Demonstrar um método cirúrgico que proporcione uma execução mais simples, não sujeito às complicações vinculadas ao tubo de ventilação. MATERIAL E MÉTODOS: Foram comparadas as técnicas de miringotomia por microlanceta e por microeletrocautério por radiofrequência (ponteira 0,3mm e 0,7mm) isolada e associada à mitomicina C, considerando o tempo de fechamento timpânico, em ratos da linhagem Wistar. Estudo experimental. RESULTADOS: Houve uma diferença estatisticamente significante entre a miringotomia por radiofrequência e por microlanceta. Ao analisar a técnica por radiofrequência com ponteira 0,7mm associada à mitomicina C (teste de Wilcoxon), o P encontrado foi menor que 0,001, demonstrando uma significância estatística. O tempo máximo de fechamento foi de 44 dias e a mediana encontrada foi de 14 dias. CONCLUSÃO: A técnica de miringotomia por radiofrequência (com ponteira de maior diâmetro) associada à mitomicina C, apresenta uma otimização no tempo de cicatrização da mesma.

This study aimed at describing an alternative surgical technique to the insertion of a ventilation tube in the tympanic membrane: myringotomy by radiofrequency alone and associated with mytomicin C. AIM: to show a surgical approach that can be simple to execute, not subject to complications arising from the ventilation tube. MATERIALS AND METHODS: we compared myringotomy by microknife and by radiofrequency microcautery (0.3 mm and 0.7 mm tips) alone and associated with mytomicin C, considering the time of tympanic closure in Wistar rats. Experimental study. RESULTS: there was a statistically significant difference between radiofrequency myringotomy and knife myringotomy. As we analyze the radiofrequency approach with the 0.7mm tip associated with mytomicin C (Wilcoxon test), the p value found was lower than 0.001, showing a statistical significance. The maximum tympanic membrane closure time was 44 days and the median found was 14 days. CONCLUSION: the radiofrequency myringotomy (with the larger diameter tip) associated with mytomicin C enhances the tympanic membrane healing time.
