Objetivo: avaliar a condição miofuncional orofacial de indivíduos com disfunção temporomandibular, caracterizar o padrão de mastigação e investigar a relação entre a condição miofuncional orofacial e o desempenho nas funções de mastigação e deglutição. Materiais e métodos: foram analisados prontuários de participantes de um projeto de extensão interdisciplinar de odontologia e fonoaudiologia. A idade mínima para compor a amostra foi 18 anos. Os participantes haviam realizado exame odontológico e avaliação fonoaudiológica, com o protocolo de Avaliação Miofuncional Orofacial com Escores. Os resultados foram apresentados por distribuição absoluta, relativa e medidas de tendência central. Foram aplicados o teste t-student para amostras independentes e correlação de Pearson para avaliar associação. O nível de significância adotado foi 5%. As análises foram realizadas no IBM SPSS Statistics 21. Resultados: Dezessete prontuários integraram a amostra. A média de idade dos participantes foi 41,2 anos (±12,2), 76,5% eram do sexo feminino. A média do escore total (AMIOFE) indicou condição miofuncional normal (92,5±5,14), porém da mastigação (7,94±1,60) e deglutição (13,1±1,17) revelam prejuízos funcionais. Não houve diferença significativa entre homens e mulheres no escore total (p=0,687), tampouco nas diferentes categorias avaliadas. Discussão: Os escores totais encontrados neste estudo, na mastigação e deglutição, estão de acordo com outras pesquisas realizadas e revelam alteração na função. Conclusão: as alterações funcionais orofaciais encontradas nos indivíduos com disfunção temporomandibular crônica deste estudo estão relacionadas com a condição miofuncional orofacial de uma maneira geral, e devem ser consideradas na elaboração de planos de tratamento, com o objetivo de proporcionar maior estabilidade aos resultados.

Background: Sleep bruxism (SB) is an oromandibular activity with teeth grinding and clenching and a masticatory muscle activity. It generates temporomandibular dysfunction (TMD), tooth wear and mobility, as well as other clinical findings. It is important to analyze occlusion and TMJ to determine how it is affected by the biomechanical load generated by bruxism. Purpose: To establish the relationship between the condylar position of the temporomandibular joint (TMJ) using cone beam computed tomography (CBCT) with the dental wear patterns determined with the BruxChecker®, in subjects with a clinical diagnosis of sleep bruxism. Methods: Observational, descriptive, cross-sectional study in 45 patients with clinical diagnosis of sleep bruxism, according to the bruxism diagnostic criteria of the AASM (American Academy of Sleep Medicine), with an average age of 34.9 ± 8.6. The CBCT were analyzed, measuring the spaces of the TMJ in the sagittal plane: anterior, superior and posterior (SA, SS, SP) and in the coronal plane: lateral, superior and medial (Cl, CS, CM). The pattern of dental wear was classified with the BruxChecker® by dividing the subjects into: Group 1, canine pattern (CP) with 19 subjects and Group 2, molar pattern (MP) with 26 subjects. Results: No significant differences were observed between the measurements of the joint spaces of each group nor in the comparison between the PC vs PM patterns. The sagittal position of the condyle posterior/anterior(P/A) was posterior and the coronal medial/lateral (M/L) was medial for the two groups, when evaluating the ratios. Significant difference (P <0.00) was found in right pattern CP and MP, when estimating the difference between averages of medial and lateral spaces. Conclusions: The position of the condyle was found posterior and medial in the articular fossa, in the right CP and in the left MP. A significant right lateral condyle position was evidenced in PC and PM. These findings indicate an altered condylar position in subjects with bruxism, which can be associated with joint distraction, possibly generated by constant eccentric mandibular movements during bruxism.

Background: Temporomandibular joint disorder is a complex disease requiring multimodal treatment and often a delayed diagnosis. Purpose: The primary objective of this study is to evaluate the feasibility of simultaneously recording joint sounds while obtaining 3-tesla cine-magnetic resonance imaging (3T cine-MRI) of the temporomandibular joint (TMJ). A secondary objective pertains to optimization of a dynamic TMJ imaging protocol to maximize image quality and speed while maintaining synchronicity. Methods: Investigators enrolled four subjects (August 2018 to August 2019) eliciting audible joint sounds during continuous open-close jaw movements during clinical evaluation at the New York University College of Dentistry. A contact fiber-optic microphone (OptiRhythm 4130, Optoacoustics, Yehuda Israel) was utilized to record joint sounds elicited with functional movements during MR dynamic imaging at NYU Langone Health and all data was recorded appropriately. Results: Results of this feasibility study demonstrate the successful integration of audio and 3-Tesla MR imaging for the TMJ in all subjects. This protocol was shown to be well-tolerated by the subjects. A precise correlation of the movement of TMJ structures within cine-MRI images and with audible observations was achieved and assessed by an experienced oral and maxillofacial surgeon and an experienced radiologist. Conclusion: This protocol for simultaneous audio/cine-MRI is a viable tool for studying TMJ health and disease. In future studies, we anticipate this protocol will ultimately refine our understanding of TMJ sounds and their relation to anatomy, physiology, and pathology. In addition, we hope to establish a diagnostic aid to guide surgical and non-surgical decision-making more precisely. [ABSTRACT FROM AUTHOR]

Background: A wide range of functional devices allow stimulating mandibular growth in class II patients, through mandibular advancement; managing to correct this type of skeletal and occlusal disharmony. Fixed repositioning appliances apply constant forces to the TMJ and may cause remodeling of the articular condyle and glenoid fossa. Computed tomography (CT) has been the gold standard for imaging the bone and hard tissues of the TMJ, but today cone beam computed tomography (HCCT) and Nuclear Magnetic Resonance (MRI) are used, because of their low and zero levels, respectively, of radiation. Objective: to measure morphological changes through TMJ imaging evaluation after correction of class II malocclusion with functional treatment with appliances in growing patients Methods: a comprehensive systematic literature search was conducted from January 2015 to May 2023 in the following bibliographic databases PubMed, EBSCO, Embase, and the Cochrane Library. Results: 10 studies were selected. The total sample size was 210 patients, and the age range was 10.3 to 14 years. The main imaging method used was HCCT with n = 9. Conclusions: The main change described is condylar remodeling, followed by morphological adaptation of the fossa. Although no significant differences have been reported in morphological changes in the TMJ between fixed versus removable functional appliances, fixed appliances cause a higher incidence of morphological changes.

The objective of the present study was to report a clinical case of a patient who presented odontogenic (dental) pain of myofascial origin associated with temporomandibular disorders (TMD). Female patient aged 50 years, in the extraoral clinical examination, in the palpation of the muscles of mastication, the patient presented PG in the region of the middle third of the masseter muscle on the right side, referring to cervical pain of the tooth 47, reproducing the main complaint, and had limited mouth opening and TMJ pain. Interproximal radiographs were performed for diagnosis. The present case was diagnosed, odontogenic (dental) pain of myofascial origin associated with TMD. The treatment was carried out in two moments, the first was carried out by the Dry Needling (SA) technique, with the function of deactivating the PG, associated with thermotherapy, and stretching, and guidelines for not clenching the teeth during wakefulness. In a second moment, in which the patient had no pain and an improvement in mouth opening, a plate was installed to stabilize the occlusion due to the bruxism that the patient had. The measures taken in the present case were effective and the patient remains under observation, without pain for more than a year. [ABSTRACT FROM AUTHOR]

Temporomandibular disorder (TMD) is a term recognized by the American Academy of Orofacial Pain as a set of disorders that involve the masticatory muscles, the temporomandibular joint (TMJ) and all associated structures. Both instrumental and manual chiropractic has been a great facilitator in the treatment of TMD, due to its ability to solve the cause of the problem, bringing very satisfactory results for clinical practice and especially for chronic patients. The aim of this study is to evaluate, through a literature review, the influence of chiropractic care on temporomandibular disorders. This study is a literature review with articles from electronic databases PubMed, ABQuiro, Google Acadêmico, Scientific Eletronic Library Online (SCIELO) e Physiontherapy Evidence Database (PEDro). Eight articles were included in is review. From the analysis made by this review study, it was possible to verify that chiropractic has been contributing more and more in this treatment. As it is a safe technique that treats the cause of pain and the entire compensation chain, it brings lasting results. [ABSTRACT FROM AUTHOR]

Temporomandibular disorders are frequent in different segments of the population and harm the quality of life of individuals. The present sudy aimed to investigate the association between stress and temporomandibular dysfunction (TMD) in university students in Brazil. All incoming students at the Federal University of Pelotas were invited to participate in this cross-sectional study. A self-administered questionnaire was used with socioeconomic and oral health variables. TMD Fonseca questionnaire "Fonseca's anamnestic index" was used to identify the severity of symptoms of temporomandibular dysfunction. The same was elaborated in the form of Helkimo's anamnestic index. Stress was measured using a modified version of the Perceived Stress Scale and categorized into quartiles. Logistic multivariable regression models were used to analyze the associations of interest controlling for possible confounding variables. A backward stepwise procedure was used to select variables that should be kept in the final model. A total of 2,089 students answered the questionnaires and 82 (3.9%) were classified with the presence of TMD. Adjusted logistic regression shows that chance of presenting temporomandibular dysfunction was higher (OR=2.43; 95%CI=1.04-5.65) when the stress level increased. In conclusion, the mild degree of temporomandibular dysfunction was the most prevalent. Stress was associated with individuals with a higher prevalence of temporomandibular dysfunction.

Resumo Diversas manobras já foram descritas para o acesso ao segmento distal cervical da artéria carótida interna ou à bifurcação carotídea alta; entretanto, há divergências na sistematização dessas técnicas. O objetivo deste estudo é revisar as técnicas descritas e propor um protocolo prático que auxilie na seleção da técnica mais adequada para cada caso. Para isso, foi realizada uma busca nas bases de dados PubMed Central, Biblioteca Virtual em Saúde e SciELO por artigos sobre o tema, em língua inglesa ou portuguesa, publicados entre os anos de 1980 e 2021. Entre as manobras descritas, parece razoável que as duas etapas iniciais sejam a abordagem ao músculo esternocleidomastóideo, seguida pela secção/retração do ventre posterior do músculo digástrico. Caso necessário, a subluxação mandibular temporária unilateral é um recurso adicional e preferível à divisão do aparato estiloide, devido ao menor potencial de morbidade. Exposições ainda mais amplas podem ser obtidas com as osteotomias mandibulares.

Introduction: The etiology of temporomandibular dysfunction is multifactorial, and causal factors include psychological conditions such as anxiety. Objective: Identify the prevalence of temporomandibular dysfunction and anxiety as well as their levels among dental students from the Federal University of Campina Grande. Methods: An inductive cross-sectional observational study was conducted of a sample of 185 dental students from the Federal University of Campina Grande. Data collection was based on Fonseca's anamnesis index and the State-Trait Anxiety Inventory. Data were analyzed by descriptive statistics and subjected to the chi-square statistical test and Fisher's exact test, with a significance level of 5 %. Results: Results show that most of the sample was female (67 %) with a mean age of 21.4 years. On the other hand, 79 % of the students had some degree of dysfunction, which was mild in most (72 %). Anxiety state and anxiety trait were more prevalent on the moderate level with 79 % and 72 % respectively. No significant statistical association was identified in the study sample between the presence and absence of temporomandibular dysfunction and anxiety, be it trait or state, with values of p= 0.484 and p= 0.297 respectively. Conclusions: High statistical prevalence was found of temporomandibular dysfunction and anxiety among dental students, hence the importance of a detailed search for those signs and symptoms during clinical examination.

Introdução: A artrocentese é uma técnica minimamente invasiva utilizada para o tratamento de desordens temporomandibulares (DTM). Consiste na lavagem do espaço articular superior, aumentando a mobilidade articular e reduzindo a dor. Esta técnica pode ser associada à viscossuplementação, que consiste na injeção intra-articular de ácido hialurônico, diminuindo o desgaste da superfície articular. Objetivo: Analisar a eficácia da artrocentese associada à viscossuplementação, ressaltando os seus benefícios, através de um relato de caso. Relato de Caso: Paciente, E.O.M. gênero feminino, 30 anos, reportou-se à Santa Casa de Misericórdia de Juiz de Fora, com queixa de dor. Foi aplicado a metodologia DC/TMD (Diagnostic Criteria for Temporomandibular Disorders) Eixo I, sendo constatada hipomobilidade articular, com abertura bucal máxima de 25 mm, estalidos, crepitação e dor na região pré-auricular. A hipótese diagnóstica de deslocamento de disco com redução através de exame de Ressonância Magnética (RM). Iniciou-se o tratamento com placa neuromiorrelaxante em conjunto com a terapia farmacológica. O quadro sintomatológico da paciente não apresentou melhora, sendo indicada a artrocentese associada à viscossuplementação com hialuronato de sódio em ambas articulações. Resultados: Foi observada melhora do quadro sintomatológico da paciente. A abertura bucal evoluiu de 25mm para 36mm, após 30 dias do procedimento. Foi realizada a proservação por dois anos, não havendo sinais de recidiva. Conclusão: Pode-se concluir que a artrocentese associada à viscossuplementação é um método eficaz para o tratamento de desordens temporomandibulares, principalmente em pacientes refratários ao tratamento conservador, sendo considerada uma técnica segura.

Introdução: A dor orofacial (DO) e as disfunções temporomandibulares (DTM) apresentam alta prevalência na população, sendo causa de grande sofrimento para os pacientes. Para formar clínicos gerais aptos em reconhecerem e tratarem tais distúrbios é necessário que as Instituições de Ensino Superior (IES) ofertem este conteúdo de forma satisfatória durante a graduação. Objetivo: Identificar e quantificar a presença da disciplina de DTM e DO nas grades curriculares dos cursos de graduação em Odontologia, bem como características curriculares da disciplina quando presente. Material e Métodos: A amostra da pesquisa constitui-se de todas as faculdades de Odontologia do Sudeste brasileiro em funcionamento no mês de março de 2019, que estavam com cursos ativos e credenciados no portal e-MEC do Ministério da Educação do Brasil, e que disponibilizaram acesso a matriz curricular por meio de ferramentas online (website oficial ou e-mail). Os dados foram analisados no programa GraphPad Prism 5.0. Resultados: Das 176 IES da região Sudeste, 144 (81,8%) foram incluídas no estudo por preencherem os critérios de inclusão. Destas, apenas 36% apresentam disciplinas relacionadas à DTM e DO em suas matrizes curriculares, sendo mais ofertada em IES públicas (52,6%) do que privadas (33,6%), para p=0,1275. A respeito da natureza da disciplina, é predominantemente obrigatória nas IES privadas, e não obrigatória nas IES públicas (p=0,0073). Como aspecto positivo, foi observado que em relação ao tipo de conteúdo abordado, disciplinas teórico-práticas são abordadas na maioria das instituições (59,37%). A carga horária (CH) média da disciplina é de 58,98h (DP=20,37), sendo maior nas IES públicas. Conclusão: Nossos resultados demostram que a maioria dos cursos de Odontologia do Sudeste brasileiro (63,8%) não oferecem disciplinas de DTM e DO, especialmente IES privadas.

RESUMO Objetivo Este estudo visou validar o Protocolo de Avaliação Miofuncional Orofacial MBGR para adultos com DTM. Método Participaram 30 adultos, sendo 15 com DTM (deslocamento de disco com redução segundo o Research Diagnostic Criteria for Temporomandibular Disorders) e 15 Controles. O processo de validação envolveu a validade de conteúdo, de critério e de construto, além da concordância inter e intra-avaliador, sensibilidade e especificidade. Considerou-se nível de significância de 5%. Resultados Foram confirmadas as validades de conteúdo, visto que o Protocolo MBGR abarca todas as questões funcionais presentes em indivíduos com DTM; de critério, com correlações significantes entre o MBGR e AMIOFE; e de construto, diferenciando indivíduos com e sem DMO quanto à dor à palpação e mobilidade mandibular, com correlação significante entre a avaliação clínica do MBGR e o uso do algômetro digital, bem como confirmação do exame instrumental para a classificação do modo respiratório. A força de concordância variou de pobre a muito boa para a análise interavaliador e de razoável a muito boa para intra-avaliador. Os valores de sensibilidade e especificidade foram elevados. Conclusão O Protocolo MBGR mostrou-se válido para aplicação em adultos com DTM com deslocamento de disco com redução e controles, contemplando todos os aspectos que possibilitam a análise das condições oromiofuncionais nesses indivíduos.

A articulação temporomandibular (ATM) possibilita a mastigação, deglutição e a fonética, faz parte do sistema estomatognático, e é capaz de múltiplos movimentos. A DTM (disfunção temporomandibular) representa certas condições musculares e articulares na região crânio orofacial que podem causar problemas nos músculos da mastigação e na ATM e suas estruturas associadas, sendo a cefaleia e a dor orofacial alguns dos principais sintomas relatados pelos pacientes. Objetivo: analisar a relação da DTM à dor orofacial e cefaleia através de uma revisão narrativa. Métodos: para a realização deste estudo, foram feitas buscas nas bases de dados Scielo e Pubmed, utilizando as palavras chave: Dor Orofacial, Disfunção Temporomandibular, Articulação Temporomandibular, Dor de Cabeça e Cefaleia. Conclusão: a partir dos artigos analisados na presente revisão foi possível concluir que existe relação entre dor na região orofacial e cefaleia com a DTM, porém ainda não é claro o mecanismo dessa correlação, sendo necessários mais estudos para elucidar esse quadro clínico.

Introdução: A pneumatização, considerada um processo fisiológico, são cavidades cheias de ar no interior dos ossos do crânio resultante de áreas de células epiteliais. Objetivo: Determinar a prevalência de pneumatização na fossa articular (PFA) e da eminência articular (PEA) do osso temporal por meio de exames de tomografia computadorizada de feixe cônico (TCFC). Material e métodos: Trezentas e noventa imagens de articulações temporomandibulares foram avaliadas por dois examinadores, devidamente calibrados, com experiência em imagens de TCFC. Nos casos em que foi detectada pneumatização, esta foi classificada de acordo com o tipo (unilocular e multilocular) e lateralidade (unilateral ou bilateral). Resultados: A PFA ou a PEA foi diagnosticada em 97 (49,74%) pacientes. Destes pacientes, 61 (31,3%) apresentaram PFA e 36 (18,5%) PEA. Em relação à lateralidade, na PFA, 36 (59%) apresentaram a condição unilateralmente e 25 (41%) bilateralmente. Dentre os pacientes com PEA, 24 (66,7%) apresentaram a condição unilateralmente e 12 (33,3%) bilateralmente. A pneumatização foi correlacionada entre os lados pelo coeficiente de correlação de Spearman e foi significativa para os casos multiloculares (fossa articular: rs=0,52 / p

RESUMO Objetivo Analisar os achados audiológicos em indivíduos com desordem temporomadibular e comparar esses achados com indivíduos sem desordem temporomanbibular. Métodos A amostra foi composta por 39 participantes adultos, de ambos os gêneros, com diagnóstico prévio de desordem temporomandibular (grupo de estudo) e 39 participantes adultos, sem desordem temporomandibular (grupo controle). Todos os participantes foram submetidos à audiometria tonal limiar em altas frequências, imitanciometria e pesquisa das emissões otoacústicas evocadas por produto de distorção. Resultados Observou-se prevalência de desordem temporomandibular no gênero feminino e a média de idade ficou acima da quarta década de vida. Na audiometria tonal limiar, foi observada ocorrência de perda auditiva do tipo neurossensorial e condutiva, no grupo de estudo, além de piores limiares auditivos em altas frequências. Em ambos os grupos, houve maior ocorrência de curva timpanométrica do tipo A, bem como diferenças entre os grupos na pesquisa do reflexo acústico ipsilateral e contralateral e no registro das emissões otoacústicas evocadas por produto de distorção. Conclusão Indivíduos com desordem temporomandibular apresentam piores resultados nos limiares auditivos, na timpanometria, nos reflexos acústicos ipsilaterais e contralaterais e nas emissões otoacústicas evocadas, quando comparados com o grupo controle.

Introduction: Temporomandibular disorder (TMD) is defined by the American Academy of Orofacial Pain as a set of disorders involving the masticatory muscles, the temporomandibular joint (TMJ) and the stomatognathic system structures. Are strong evidence of the psychosomatic component installation and worsening of TMD, however, further studies are required in order. Objective: To investigate the relationship between anxiety and TMD in College of Nursing and Physiotherapy courses at the Catholic University of Goiás (PUC Goiás) Methods: This is an epidemiological, prospective analytical study involving 181 individuals. Participants underwent Helkimo index and the Hamilton Rating Scale for assessment of TMD and anxiety disorder, respectively. Results: The prevalence of TMD in the research participants was 91.71%, corresponding to 166 cases, and the mild and moderate TMD were most common. Regarding the anxiety disorder, 66.85% of the university presented, corresponding to 121 cases, with severe and moderate the most common. The anxiety disorder is significantly more present in subjects with TMD, given the fact that the value of p in this analysis of correlation was 0.01. Conclusion: College of Physiotherapy and Nursing courses, mostly, presented TMD and anxiety disorder and both are associated. [ABSTRACT FROM AUTHOR]

Objective: To assess changes in the articular surfaces of the temporomandibular joint (TMJ) and in condylar translation, as detected by magnetic resonance imaging (MRI), determining whether such changes correlate with disc displacement. Materials and Methods: We retrospectively analyzed the MRI scans of 2076 TMJs of 1038 patients with symptoms of temporomandibular disorder. We attempted to determine whether articular disc deformity and changes in condylar translation, as well as changes in the articular surfaces of the condyle, glenoid fossa, and articular eminence, correlated with disc displacement. Results: Disc displacement with reduction was associated with changes in the shape of the articular eminence. Disc displacement without reduction was most strongly associated with disc deformity, condylar degeneration, glenoid fossa degeneration, and effusion. Neither decreases nor increases in condylar translation were associated with disc deformity, degenerative bone changes, or disc displacement. Conclusion: Changes in the shape of the articular eminence seem to predispose to progression of internal derangement of the TMJ. [ABSTRACT FROM AUTHOR]

Introduction: temporomandibular disorder (TMD) is a set of factors that are associated with joint noises and pain in adjacent muscles, also include limitation of joint movements of the jaw, pain in the face and head. Objective: to investigate the acute effects on the range of motion (ROM) of mouth opening and intensity of pain in individuals with TMD undergoing global postural exercises. Methods: volunteers of both sexes with a diagnosis of TMD according to the Diagnostic Criteria for Temporomandibular Disorders (RDC / TMD) were included in the study. To assess pain, a Palpeter® painter with an accuracy of 0.5 kg and 1.0 kg was used in the facial muscles defined by RDC / TMD. To measure the mouth opening ROM, a pachymeter was used with one decimal place. All evaluative measures were performed before and after the end of the intervention protocol with global postural exercises. Results: in relation to the pain intensity, there was a significant difference in the left and right upper right masseter muscles. In the mouth opening ROM there was a statistically significant difference between the moments, but there was no difference when compared between groups. Conclusion: the global postural exercise program contributed to the reduction in the limitation of mouth opening ROM and decrease of pain in the masseter muscle. [ABSTRACT FROM AUTHOR]

Conclusão: os valores da amplitude dos movimentos mandibulares de acordo com idade, gênero e altura, para a população estudada, foram descritos e podem contribuir como um referencial que pode auxiliar na avaliação funcional do sistema mastigatório.

Abstract Introduction Temporomandibular disorders (TMD) can compromise masticatory performance due to the presence of pain, muscular dysfunction and limitation of mandibular movements. Substantial improvements in TMD pain can be achieved through therapeutic approaches including education and self-care. Objective The aim of the present study was to investigate the impact of these treatment modalities in the masticatory performance of women with painful TMD. Material and method Fifty-two women were randomly divided into three groups: Control Group (CG); Education Group (received education about TMD) (EG); Self-Care and Education Group (received education about TMD and instructions self-care therapies) (SEG). The education instructions about TMD and self-care therapies were transmitted through a video and printed illustrative material. The masticatory performance was evaluated through the sieves method with natural tested foods in the evaluation periods: baseline evaluation, 30 days after and 60 days of follow-up. Data were analyzed and used with a one-way ANOVA parametric test for mean comparison of CG, EG and SEG groups (α = 0.05). Result The masticatory performance of the participants was similar, irrespective of the proposed treatments, at baseline (p=.604), 30 days (p=.450) and 60 days (p=.669). Conclusions The results indicated that treatment with educational and self-care therapies over a period of 60 days had no impact on the masticatory performance of women with painful TMD.

Introdução: A obtenção de imagens confiáveis das estruturas que formam a articulação temporomandibular sempre foi um desafio para os profissionais que trabalham no estudo e tratamento dos problemas que acometem essa articulação. Objetivo: Tendo em vista que o ligamento discomaleolar pode promover a união entre a articulação temporomandibular e a orelha média, e que distúrbios auditivos geralmente estão relacionados aos quadros de disfunções temporomandibulares promovendo dificuldade em diagnosticá-la, este estudo concerne em propor anatomicamente, uma orientação para identificação do ligamento que servirá de orientação para captura de imagens do ligamento discomaleolar na fissura petrotimpânica. Métodos: Subsidiada por dissecação cadavérica, a mensuração de planos através de secções em crânio seco através da formação de um protótipo tridimensional foi obtida. O estudo teve liberação do Departamento de Anatomia da Universidade Federal de Pernambuco - UFPE. Conclusão: As linhas de orientação geradas a partir do estudo anatômico-topográfico são eficazes na determinação do ligamento discomaleolar em imagens radiológicas.

RESUMO Introdução: A disfunção temporomandibular (DTM) é complexa e multifatorial. São encontrados, na literatura, estudos que comparam diferentes métodos de tratamento. Objetivo: Investigar estudos sobre o tratamento das disfunções temporomandibulares (DTMs) nas diversas áreas da saúde, avaliando a eficácia das técnicas empregadas, principalmente no que se refere ao uso da terapia miofuncional orofacial. Estratégia de pesquisa: Os artigos compilados neste estudo foram selecionados por meio da base de dados PubMed, utilizando os descritores “temporomandibular disorders and oral motor therapy”, “orofacial myofunctional therapy and temporomandibular disorders” e “temporomandibular disorders and myofunctional rehabilitation”. O levantamento realizado limitou-se aos artigos publicado nos idiomas Inglês e Português, entre janeiro de 2006 e dezembro de 2016. Critérios de seleção: Foram incluídos artigos sobre os tratamentos das DTMs associados aos exercícios musculares e/ou terapias manuais. Publicações sem acesso completo, repetidas por sobreposição das palavras-chave, revisões de literatura, cartas ao editor e não relacionadas diretamente ao tema foram excluídas. Resultados: Dos 102 estudos selecionados, 22 atenderam aos critérios estabelecidos. Em geral, a maioria dos tratamentos descritos apresentou efeitos benéficos para pacientes com DTMs. Foi observada grande variabilidade da metodologia adotada para a aplicação e verificação dos efeitos dos tratamentos e somente poucos estudos fizeram uso de grupo controle. Conclusão: Apesar do crescimento no número de pesquisas sobre DTMs, ainda não é possível estabelecer qual a melhor técnica de tratamento. Após análise dos artigos selecionados, observou-se que as técnicas combinadas de terapia (ex.: exercício associado ao uso de equipamento para redução da dor) produzem melhores resultados, com maior redução da dor e melhora da mobilidade mandibular.

INTRODUCTION: Internal derangements (ID) of the temporomandibular joint (TMJ) have a multifactorial etiology and are most often treated conservatively by splints, physical therapy and medications. Only in 2-5% of cases are the treatment surgical, either by arthroscopy or arthrotomy.OBJECTIVE: To evaluate improvement of mouth opening, pain relief during function, position of the articular disk and complications following Arthroscopic Lyse and Lavage (ALL).METHODS: A prospective study of 78 patients (138 TMJs) with TMJ ID, 5 males and 73 females, mean age 29.7 years, treated between January 2010 and April 2013, who were refractory to conservative treatment, had limited mouth opening and pain localized to the TMJ during function, and who were submitted to TMJ ALL and followed for a period of 12 months, with periodic reviews.RESULTS: ALL was effective in 93.6% of cases, with 85.3% experiencing improvement in mouth opening and 91.2% in pain reduction during function, 63% improvement in disk position and a rate of complications of 6.2%.CONCLUSION: In this study the ALL exhibited a high rate of success with low morbidity in internal derangements of the TMJ.
