ABSTRACT

As indicações de tratamento das fraturas mandibulares em paciente pediátrico variam em conservador, fixação não rígida e interna rígida. Alterações no crescimento ósseo, disfunções na articulação temporomandibular e assimetrias faciais podem ser decorrentes ao insucesso do tratamento. O objetivo deste trabalho consiste em relatar abordagem cirúrgica em fratura de sínfise e côndilo mandibular bilateral em paciente pediátrico. Paciente gênero feminino, 09 anos de idade, foi encaminhada ao Hospital Geral do Estado - Bahia vítima de queda de nível, cursando com trauma em face. Apresentou queixa principal, referida pela progenitora, de dificuldades em fechar a boca. Ao exame físico, a paciente apresentou mobilidade atípica à manipulação da mandíbula, mordida aberta anterior, equimose sublingual, ausência das unidades dentárias 74 e 75, com abertura bucal regular e suturas em posição em região de mento. Ao exame de imagem de tomografia computadorizada da face, pôde-se notar sinais sugestivos de fratura em região de sínfise e côndilos mandibulares bilateral. Após diagnóstico das fraturas, a paciente foi submetida à cirurgia sob anestesia geral para redução e fixação das mesmas. Realizou-se acessos em ferimento na região mentual e retromandibular bilateral com posterior síntese das fraturas utilizando fixação interna rígida com placas do sistema 2.0mm, associada a odontossíntese na fratura de sínfise. Ao acompanhamento periódico, a eleição do tratamento cirúrgico para fraturas mandibulares em pacientes pediátricos, pode permitir segurança no crescimento ósseo mandibular e facial(AU)


The indications for treatment of mandibular fractures in pediatric patients vary from conservative, non-rigid fixation and rigid internal fixation. Changes in bone growth, temporomandibular joint disorders and facial asymmetries may be due to treatment failure. The objective of this work is to report a surgical approach to bilateral symphysis and mandibular condyle fractures in a pediatric patient. Female patient, 9 years old, was sent to the State General Hospital - Bahia, victim of a fall in level, suffering from trauma to the face. She presented a main complaint, mentioned by her mother, of difficulties in closing her mouth. On physical examination, the patient presented atypical mobility when manipulating the jaw, anterior open bite, sublingual ecchymosis, absence of dental units 74 and 75, with regular mouth opening and sutures in position in the chin region. When examining the computed tomography image of the face, signs suggestive of fracture in the region of the symphysis and bilateral mandibular condyles were noted. After diagnosis of the fractures, the patient underwent surgery under general anesthesia to reduce and fix them. Access was performed on a wound in the mental and bilateral retromandibular region with subsequent synthesis of the fractures using rigid internal fixation with 2.0mm system plates, associated with odontosynthesis in the symphysis fracture. With periodic monitoring, the choice of surgical treatment for mandibular fractures in pediatric patients can allow for safe mandibular and facial bone growth(AU)

ABSTRACT

Introduction: Mandibular fractures are the most common facial fractures affecting various anatomical sites of the mandible. Among the various mandibular fractures, management of condylar fractures remains a challenging task for surgeons. Case Report: We report the case of a 28 year old male patient who presented with pain in the chin and restricted mouth opening. Computed tomography revealed a sagittal fracture of the right condylar head with medial displacement of the fractured fragments. Management of diacapitular fractures includes open reduction and internal fixation of the right condyle using a single lag-screw. Results: The postoperative outcomes were favorable, where normal mandibular movements, desired dental occlusion and exact positioning of the condyle with rigid fixation were established thereby maintaining the shape of the condyle. Conclusion: Use of single lag screw fixation is highly recommended as it greatly supports the stabilized fracture fragments and also aid in prevention of fracture fragment rotation medially.


Introducción: Las fracturas mandibulares son las fracturas faciales más comunes que afectan a diversos sitios anatómicos de la mandíbula. Entre las diversas fracturas mandibulares, el manejo de las fracturas condilares sigue siendo una tarea desafiante para los cirujanos. Reporte del Caso: Presentamos el caso de un paciente masculino de 28 años que consultó por dolor en el mentón y restricción de la apertura de la boca. La tomografía computarizada reveló una fractura sagital de la cabeza condilar derecha con desplazamiento medial de los fragmentos fracturados. El tratamiento de las fracturas diacapitulares incluye la reducción abierta y la fijación interna del cóndilo derecho con un solo tirafondo. Resultados: Los resultados postoperatorios fueron favorables, donde se establecieron los movimientos mandibulares normales, la oclusión dentaria deseada y el posicionamiento exacto del cóndilo con fijación rígida manteniendo así la forma del cóndilo. Conclusión: Se recomienda encarecidamente el uso de una fijación con un solo tornillo de tracción, ya que soporta en gran medida los fragmentos de fractura estabilizados y también ayuda a prevenir la rotación medial de los fragmentos de fractura.

ABSTRACT

The displacement of the mandibular condyle into the cranial fossa is an uncommon event; when it occurs, there is a need for immediate and multidisciplinary surgical intervention. Due to its rare advent, there is still no consolidated service dynamics, as this condition has not yet been described in a sedimented way in the literature databases. In the present article, we performed a literature review of condylar dislocation for the intracranial fossa described in the past 10 years in the PubMed and Lilacs search databases.

ABSTRACT

As fraturas faciais em crianças são raras, já que os ossos faciais pediátricos têm maior elasticidade, menos pneumatização, tecido adiposo circundante mais espesso e mais estabilização da mandíbula e maxila pelos dentes não irrompidos. Em geral, lesões nos tecidos moles são mais comuns em crianças do que fraturas esqueléticas. Entre as fraturas faciais pediátricas, as fraturas da mandíbula são as mais comuns, sendo o côndilo a área mais acometida em pacientes pediátricos. O côndilo é considerado o principal centro de crescimento da mandíbula em crianças, assim é de suma importância a definição do tratamento adequado, pautado em diversos critérios de avaliação, com o intuito de erradicar possíveis complicações advindas da fratura condilar. Assim o objetivo deste estudo é relatar um caso de fratura de côndilo unilateral em uma criança, na qual realizou-se abordagem cirúrgica com fixação interna, afim de elucidar e discutir as possíveis condutas terapêuticas acerca de tratamentos a serem aplicados, visto que esses ainda são bastante controversos na literatura e os resultados das diversas condutas são os mais diversos, apresentando variados aspectos que interferem na evolução dos pacientes(AU)


Facial fractures in children are rare, since pediatric facial bones have greater elasticity, less pneumatization,thicker surrounding adipose tissue and more stabilization of the jaw and jaw by unerupted teeth.In general, soft tissue injuries are more common in children than skeletal fractures.Among pediatric facial fractures, mandible fractures are the most common, with condyl being the most affected area in pediatric patients.The condyl is considered the main center of mandible growth in children, so it is of Paramount importance to define the appropriate treatment, based on several evaluationcriteria, in order to eradicate possible complications resulting from the condilar fracture.Thus, the aim of this study is to report a case of unilateral condyl fracture in a child, in which a surgical approach with internal fixation was performedin order to elucidate and discuss the possible therapeutic approaches about treatments to be applied, since these are still quite controversial in the literature and the results of the various behaviors are the most diverse,presenting several aspects that interfere in the evolution of patients(AU)

ABSTRACT

Resumen Introducción: Las fracturas de cóndilo presentan una alta incidencia dentro de las fracturas de mandíbula. Son principalmente tratadas por reducción abierta y fijación interna mediante elementos de osteosíntesis (ORIF) o por reducción cerrada (CR) con fijación máxilo-mandibular (MMF). El tratamiento asistido por endoscopio de estas fracturas, ofrece una alternativa y complemento quirúrgico a las limitaciones que se pueden presentar en la ORIF clásica. Objetivo: Describir la técnica de reducción quirúrgica asistida por endoscopio mediante acceso transoral y acceso retromandibular, como complemento a la técnica quirúrgica convencional para el tratamiento de fracturas de cóndilo mandibular, evaluando criterios clínicos en una serie de casos operados por esta técnica. Materiales y Método: Estudio descriptivo de presentación de serie de casos de pacientes con fractura de cóndilo, tratados con reducción quirúrgica asistida por endoscopio mediante accesos transoral y retromandibular, entre los años 2017 y 2018. Resultados: De los siete pacientes operados, un 85,7% presentó una función mandibular normal, un 100% presentó una función motora neurológica facial normal y un 71,4% no presentó dolor posoperatorio en el control de los 6 meses. Todos los pacientes recuperaron la oclusión que tenían de forma previa a la fractura mandibular. No se reportaron casos que tuvieran la necesidad de reintervención quirúrgica. Conclusiones: La reducción quirúrgica asistida por endoscopio para las fracturas de cóndilo mandibular es una técnica que ofrece un complemento a la técnica quirúrgica convencional, permitiendo mayor visibilidad de las estructuras, menor morbilidad quirúrgica y complicaciones mínimas en relación a las técnicas convencionales descritas.


Introduction: Condyle fractures have a high incidence within jaw fractures. They are mainly treated by open reduction and internal fixation with osteosynthesis elements (ORIF), or by closed reduction (CR) with maxillomandibular fixation (MMF). Endoscopic-assisted treatment of these fractures offers an alternative and surgical complement to the limitations that can occur in classic ORIF. Aim: To describe the technique of endoscope-assisted surgical reduction using transoral access and retromandibular access, as a complement to the conventional surgical technique for the treatment of mandibular condyle fractures, evaluating clinical criteria in a series of cases operated by this technique. Materials and Method: Descriptive study of case series presentation of patients with condyle fracture, treated with endoscopic assisted surgical reduction by transoral and retromandibular access, between the years 2017 and 2018. Results: Of the seven patients operated on, 85.7% presented normal jaw function, 100% presented normal facial neurological motor function, and 71.4% presented no postoperative pain at the 6-month control. All patients recovered the occlusion they had prior to the mandibular fracture. There were no reported cases in need of surgical reintervention. Conclusions: Endoscope-assisted surgical reduction for mandibular condyle fractures is a technique that offers a complement to the conventional surgical technique, allowing greater visibility of the structures, less surgical morbidity and minimal complications in relation to the conventional techniques described.

ABSTRACT

RESUMEN Fundamento: Los odontomas son entidades odontogénicas benignas mixtas, compuestas por una mezcla de células odontogénicas epiteliales y mesenquimatosas diferenciadas, las mismas pueden ser compuestas y complejas. Los hallazgos radiográficos de estos tumores en posiciones supernumerarias son raras menores al 1 %. Objetivo: Describir el caso clínico de un odontoma complejo infrecuente. Presentación de caso: Paciente femenina de 18 años con un trauma facial, que durante el diagnóstico imagenológico se le encontró una imagen anterosuperior de aspecto tumoral en posición supernumeraria, por lo que se decidió realizar la exéresis quirúrgica de la lesión después de finalizado el tratamiento del trauma. El diagnóstico clínico histopatológico fue de un odontoma complejo. Conclusiones: Se recomienda realizar las vistas imagenológicas tipo ortopantomografías o panorámicas a cada paciente que vaya a ser operado de cirugía bucal a fin de poder detectar de forma precoz cualquier alteración en la anatomía y de esta manera estudiar tanto el comportamiento de los odontomas como de otras lesiones intraóseas, lo que puede garantizar un tratamiento temprano y con ello un mejor pronóstico para el paciente.


ABSTRACT Background: Odontomas are mixed benign odontogenic entities, composed of a mixture of odontogenic epithelial and differentiated mesenchymal cells, they can be compound and complex. Radiographic findings of these tumors in supernumerary positions are rare, less than 1%. Objective: To describe the clinical case of a non-frequent complex odontoma. Case report: 18-year-old female patient with facial trauma, during the imaging diagnosis it was found an anterosuperior tumor image in supernumerary position, thus decided to perform the surgical excision of the lesion after the trauma treatment. The histopathological clinical diagnosis was a complex odontoma. Conclusions: It is recommended to perform standard panoramic radiograph imaging for each patient to be operated on oral surgery to detect any early anatomy alteration, so this way to study both, the behavior of odontomas as well as other intraosseous lesions, which can guarantee an early treatment and a better prognosis for the patient.

ABSTRACT

La laterodesviación mandibular es una de las anomalías dentoesqueletales sobre las que hay que intervenir tempranamente, ya que, libradas a su evolución, desembocan en una asimetría facial que podría ser de resolución ortodóncicoquirúrgica. Dado que la población infantil puede estar expuesta a diferentes tipos de traumatismos en el área facial, es que se hace necesaria la evaluación exhaustiva del paciente con seguimiento a lo largo de su crecimiento y desarrollo. Se presenta un caso clínico de un paciente, a modo ilustrativo.(AU)


Mandibular laterognathia is one of dentofacial deformities which need an early diagnosis since if they evolve naturally, they lead to a facial asymmetry that could be of surgical-orthodontic solution. As pediatric population can be exposed to many different types of facial trauma, it becomes necessary a thorough examination of the patient with a follow up through out growth and development. A case report is presented for illustrative purposes.(AU)

ABSTRACT

RESUMEN: Las fracturas de cóndilo mandibular son frecuentes en el trauma maxilofacial. Pueden tratarse ortopédicamente o en forma quirúrgica, dependiendo principalmente de las características morfológicas y funcionales del caso, y también de la experiencia del cirujano y los recursos disponibles. En los últimos años se ha establecido una corriente proclive al tratamiento quirúrgico, basada en la rápida recuperación del enfermo y la disminución de las secuelas funcionales y estéticas. Sin embargo, el tratamiento ortopédico bien indicado y ejecutado, puede ser una buena alternativa de tratamiento y que debe ser considerada dentro de las propuestas terapéuticas. El Objetivo de este estudio, es presentar una serie de tres casos de pacientes afectados por fracturas de cóndilo mandibular, tratados en forma ortopédica, en el Hospital El Carmen Dr. Luis Valentín Ferrada, Santiago - Chile. Además, se presentará una revisión de las dos tendencias de tratamiento con énfasis en las indicaciones y protocolo adecuado de tratamiento ortopédico.


ABSTRACT: The Mandible condyle fracture, are common in maxillofacial trauma. They can be treated orthopedically or surgically, depending on the characteristics of the case, the available means and the experience of the surgeon. In recent years, a trend has been established that is prone to surgical treatment, based on the patient's rapid recovery and the reduction of aesthetic and functional sequelae. However, orthopedic treatment can be an excellent treatment alternative. This is why today the treatment of mandibular condyle fractures has become a controversy in the specialty. The objective of this report is to present a series of three cases of patients with mandibular condylar fractures, treated orthopedically, at the Carmen Clinical Hospital, Santiago - Chile. In addition with a brief review of the two treatment trends will be presented with emphasis on the indications and appropriate protocol of orthopedic treatment.

ABSTRACT

Objetivo: relatar um caso de fratura na região parassinfisária e côndilar bilateral após acidente ciclístico, tratada pela técnica de bloqueio maxilomandibular. Relato de caso: paciente do gênero feminino, 21 anos, deu entrada no Hospital Municipal Waldemar das Dores, Barão de Cocais, MG, vítima de acidente ciclístico, apresentando fratura de esmalte e dentina nos dentes 11 e 21, mordida aberta anterior, com incapacidade de atingir a máxima intercuspidação, juntamente com uma limitação de excursão lateral para o lado direito. Após exames tomográficos, foi constatada fratura completa de colo de côndilo direito, fratura em galho verde em côndilo esquerdo e fratura de cortical lingual parassinfisária. Por se tratar de uma paciente jovem e por apenas uma de suas fraturas apresentar-se completa (colo do côndilo direito), foi proposto tratamento fechado, por meio do bloqueio maxilomandibular. Conclusão: o bloqueio maxilomandibular foi considerado um tratamento eficaz no caso em questão, no qual foi possível estabelecer a consolidação das fraturas sem ocorrência de complicações pós-tratamento.(AU)


Objective: to report a case of fracture in the bilateral parasymphyseal and condylar region after a cycling accident, treated with the maxillomandibular block technique. Case report: a 21-yearold female patient was admitted to the Waldemar das Dores Municipal Hospital, Barão de Cocais, MG, Brazil, victim of a cycling accident, showing enamel and dentin fracture in teeth 11 and 21, anterior open bite, inability to reach maximum intercuspation, and a lateral excursion limitation to the right side. Tomographic examinations showed complete fracture of the right condyle neck, greenstick fracture in the left condyle, and parasymphyseal lingual cortical fracture. Considering it is a young patient with only one complete fracture (neck of the right condyle), a closed treatment was proposed through maxillomandibular block. Conclusion: maxillomandibular block was considered an effective treatment for the case in question, allowing to establish fracture consolidation without post-treatment complications.(AU)

ABSTRACT

Objetivo: apresentar um relato de caso clínico de uma criança de 4 meses de idade que sofreu uma fratura do côndilo após queda e foi submetida a tratamento conservador, discutindo aspectos que determinaram a opção por esta conduta. Relato de caso: paciente apresentava, no exame clínico, discreto edema na região do mento e não apresentava limitação da abertura bucal. Devido a estes achados clínicos e à idade do paciente, mesmo com imagem tomográfica evidenciando a fratura condilar, optou-se pela realização de tratamento conservador e acompanhamento clínico do paciente. Considerações finais: a decisão da conduta terapêutica deve ser baseada em exames físicos, clínicos e imaginológicos do paciente. Em pacientes muito jovens, como o relatado neste caso, é preciso ter cautela com a indicação dos procedimentos a serem realizados, pois é um paciente que está em intenso desenvolvimento e crescimento. O acompanhamento em longo prazo da manutenção de movimentação fisiológica da articulação temporomandibular do paciente também é fundamental para que se tenha sucesso no tratamento escolhido, evitando-se patologias como a anquilose ou outras alterações que dificultem uma abordagem mais conservadora ou minimamente invasiva. (AU)


Objective: the present study report a clinical case of a 4-month-old child who suffered a condyle fracture after falling and submitted to a conservative treatment, discussing issues that determined the option for this management. Case report: patient presented, on clinical examination, mild edema in the ment region and did not presented limitation of the oral opening. Due to these clinical findings and the patient's age, even with a tomographic image evidencing the condylar fracture, we chose to perform conservative treatment and clinical follow-up of the patient. Final considerations: the therapeutic management decision should be based in patient's physical, clinical and imaging examinations. In very young patients, as reported here, care should be taken to indicate the procedures to be performed, as it is a patient who is in intense development and growth. Long-term follow-up of the maintenance of the physiological movement of TMJ is also fundamental for the success of the treatment, avoiding pathologies such as ankylosis or other changes that hinder a more conservative or minimally invasive approach.

ABSTRACT

INTRODUCCIÓN: Las fracturas maxilofaciales se asocian a importante morbilidad, pérdida de función y secuelas estéticas, entre otros. Dentro de las fracturas mandibulares, las fracturas de cóndilo mandibular son las más frecuentes. Estas pueden ser tratadas mediante un tratamiento quirúrgico (reducción abierta más estabilización con miniplacas de titanio) o un tratamiento conservador (ortopédico). MÉTODOS: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos ocho revisiones sistemáticas que en conjunto incluyen 66 estudios primarios, de los cuales, seis corresponden a ensayos aleatorizados. Concluimos que, en comparación con el tratamiento conservador, el tratamiento quirúrgico en fracturas de cóndilo mandibular probablemente se asocia a menor dolor articular, menor maloclusión y menor desviación lateral en apertura bucal.


INTRODUCTION: Maxillofacial fractures are associated with significant morbidity, loss of function and aesthetic sequelae, among others. Within mandibular fractures, mandibular condylar fractures are the most frequent. These can be treated by surgical treatment or conservative treatment (orthopedic). METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified eight systematic reviews including 66 primary studies overall, of which six were randomized trials. We concluded surgical treatment of mandibular condyle fractures, compared to conservative treatment, is probably associated with less joint pain, less malocclusion and less lateral deviation in buccal opening.

ABSTRACT

Las fracturas mandibulares son las fracturas más comunes de los huesos faciales; las de cóndilo mandibular ocupan un lugar importante entreellas. Dentro de sus factores etiológicos destacan los accidentes detránsito, agresión por terceras personas, accidentes deportivos y laborales. Existe gran controversia en el manejo de dicha entidad en cuantoa la elección de un tratamiento conservador o quirúrgico; hay varios factores considerados como razones para llevar a cabo el tratamiento quirúrgico, como la pérdida de altura facial posterior, la posición delcóndilo fracturado o la posibilidad de que el paciente adquiera el material de osteosíntesis. En este artículo presentamos una alternativa en el manejo quirúrgico de fracturas condilares mediante técnica de Boyne, así como una breve descripción de la técnica quirúrgica que empleamos en el Servicio de Cirugía Oral y Maxilofacial del Centro Médico Licenciado Adolfo López Mateos, la cual nos ha proporcionado adecuados resultados estéticos y funcionales.


Mandibular fractures are the most common fractures of the facial bones, with mandibular condylar fractures occupying an important place among them. Some of their etiological factors are traffic accidents, aggressions by third persons, sports, and work accidents.There is great controversy in the management of this entity, regardingthe selection of a conservative or surgical treatment; several factorsare considered reasons to carry out the surgical treatment, such as the loss of posterior facial height, the position of the fractured condylar, aswell as the possibility of having the patient purchase the osteosynthesis material. In this article, we present an alternative in the surgical management of condylar fractures using Boyne’s technique, as wellas a brief description of the surgical technique we used in the Oraland Maxillofacial Surgery Service of the Medical Center «Licenciado Adolfo Lopez Mateos¼, which has provided us with Suitable aestheticand functional results.

ABSTRACT

Abstract Objective: To evaluate the effect of bite positions characterizing different splint treatments (anterior repositioning and stabilization splints) on the disc-condyle relation in patients with TMJ disc displacement with reduction (DDwR), using magnetic resonance imaging (MRI). Material and Methods: 37 patients, with a mean age of 18.8±4.3 years (7 male and 30 females) and diagnosed with DDwR based on the RDC/TMD, were recruited. MRI metrical analysis of the spatial changes of the disc/condyle, as well as their relationships, was done in three positions: maximum intercuspation (Position 1), anterior repositioning splint position (Position 2), and stabilization splint position (Position 3). Disc/condyle coordinate measurements and disc condyle angles were determined and compared. Results: In Position 1, the average disc-condyle angle was 53.4° in the 60 joints with DDwR, while it was −13.3° with Position 2 and 30.1° with Position 3. The frequency of successful "disc recapture" with Position 2 was significantly higher (58/60, 96.7%) than Position 3 (20/60, 33.3%). In Positions 2 and 3, the condyle moved forward and downward while the disc moved backward. The movements were, however, more remarkable with Position 2. Conclusions: Anterior repositioning of the mandible improves the spatial relationship between the disc and condyle in patients with DDwR. In addition to anterior and inferior movement of the condyle, transitory posterior movement of the disc also occurred.

ABSTRACT

RESUMO Objetivo Realizar a caracterização da performance motora orofacial de indivíduos adultos com fratura em côndilo, comparando indivíduos submetidos à redução aberta e fechada. Método 26 adultos divididos em três grupos: G1 – composto por 8 indivíduos submetidos à redução aberta para correção da fratura em côndilo; G2 – composto por 9 indivíduos submetidos à redução fechada para correção da fratura em côndilo; GC – 9 indivíduos voluntários saudáveis, sem alterações do sistema miofuncional orofacial. Todos os participantes foram submetidos à avaliação que consistiu na aplicação de um protocolo clínico para a avaliação da motricidade orofacial, a amplitude dos movimentos mandibulares e a avaliação da musculatura mastigatória por meio da eletromiografia de superfície (EMGs). Resultados Os resultados indicaram que ambos os grupos com fratura de côndilo se diferenciaram significantemente do grupo controle, apresentando prejuízo na mobilidade dos órgãos fonoarticulatórios e nas funções de mastigação e deglutição. Para as medidas de amplitude mandibular, os grupos se diferenciaram do grupo controle apresentando maior restrição de movimentos. Na avaliação dos músculos mastigatórios por meio da EMGs, G2 se diferenciou de G1 e de GC, apresentando maior assimetria no funcionamento do músculo masseter. Conclusão Os resultados sugerem que, independentemente do tratamento adotado para correção da fratura no período de até 6 meses após a correção, o desempenho motor oral e a amplitude dos movimentos mandibulares se mantêm iguais para os pacientes submetidos à redução aberta ou fechada das fraturas condilares. A redução aberta parece favorecer a simetria no funcionamento do músculo masseter.


ABSTRACT Purpose To characterize the oral-motor system of adults with mandibular condyle facture comparing the performance of individuals submitted to open reduction with internal fixation (ORIF) and closed reduction with mandibulomaxillary fixation (CRMMF). Methods Study participants were 26 adults divided into three groups: G1 – eight individuals submitted to ORIF for correction of condyle fracture; G2 – nine individuals submitted to CRMMF for correction of condyle fracture; CG – nine healthy volunteers with no alterations of the orofacial myofunctional system. All participants underwent the same clinical protocol: assessment of the orofacial myofunctional system; evaluation of the mandibular range of motion; and surface electromyography (sEMG) of the masticatory muscles. Results Results indicated that patients with condyle fractures from both groups presented significant differences compared with those from the control group in terms of mobility of the oral-motor organs, mastication, and deglutition. Regarding the measures obtained for mandibular movements, participants with facial fractures from both groups showed significant differences compared with those from the control group, indicating greater restrictions in mandibular motion. As for the analysis of sEMG results, G1 patients presented more symmetrical masseter activation during the task of maximal voluntary teeth clenching. Conclusion Patients with mandibular condyle fractures present significant deficits in posture, mobility, and function of the oral-motor system. The type of medical treatment does not influence the results of muscle function during the first six months after fracture reduction. Individuals submitted to ORIF of the condyle fracture present more symmetrical activation of the masseter muscle.

ABSTRACT

Fraturas de côndilo são comuns, e a melhor maneira de tratá-las tem sido extensivamente discutida na literatura. Há basicamente dois métodos distintos para tratar fraturas de côndilo, o método funcional e o método cirúrgico. No presente estudo, o paciente foi submetido à anestesia geral para realizar o método de redução aberta com fixação interna. Após ser realizada uma abordagem submandibular para acessar a região da fratura, uma perfuração, usando broca, foi realizada na base do segmento condilar e um parafuso longo (11 mm) foi inserido, deixando uma parte (6 mm) extra-ósseo. Um sulco foi feito na parte lateral do ramo mandibular para alocação da parte extra-óssea do parafuso. Após redução e estabilização do segmento condilar, uma miniplaca de 2.0 mm foi instalada por cima do parafuso deixando a cabeça do parafuso mais inferiormente para maximizar a retenção. O paciente teve uma recuperação pós-operatória rápida, e função a função mastigatória foi reestabelecida...


Mandibular condyle fractures are common and the best approach to treating them has been extensively discussed in the literature. There are basically two different approaches to treatment of condyle fractures: the functional method and the surgical method. In the case described here, the patient underwent general anesthesia for open reduction and internal fixation. After a submandibular approach to access the fracture site, a bur was used to make a perforation in the base of the condylar segment and a long screw (11 mm) was inserted in place leaving a portion protruding from the bone (6 mm). A groove was made in the lateral part of the mandibular ramus to accommodate the extra osseous portion of the screw. After reduction and stabilization of the condylar segment, a 2.0 mm miniplate was installed over the screw leaving the screw head in an inferior position to maximize retention. The patient enjoyed a rapid postoperative recovery and early jaw function was restored in a short period of time...

ABSTRACT

OBJECTIVE: This study analyses the different parts of the upper airway space and the changes in hyoid position. The results provide a clinical reference for developing timely and effective treatment programmes for patients with mandibular fractures caused by maxillofacial trauma. METHODS: Standard X-cephalometric measurements of the lateral skull of 210 subjects were taken. The subjects were divided into four fracture groups: condylar, mandibular angle, mandibular body, and parasymphyseal. RESULTS: The radiographs of the mandibular fracture groups were compared with the normal occlusion group to analyse the upper airway space and the changes in hyoid position. Different types of fractures have different effects on the upper airway space. Bilateral mandibular body fracture and the parasymphyseal fracture have a significant influence on the lower oropharyngeal and laryngopharyngeal airway spaces, with serious obstructions severely restricting the ventilatory function ofpatients. CONCLUSIONS: Fractures at different parts of the mandibular structure are closely related to the upper airway and hyoid position.


OBJETIVO: Este estudio analiza las diferentes partes del espacio de las vías respiratorias superiores y los cambios de posición hioidea. Los resultados proporcionan una referencia clínica para desarrollar programas de tratamiento oportuno y eficaz para los pacientes con fracturas de la mandíbula, causadas por trauma maxilofacial. MÉTODOS: Se hicieron mediciones X-cefalométricas estándares del cráneo lateral a 210 sujetos. Los sujetos fueron divididos en cuatro grupos de fractura: ángulo mandibular, condilar, cuerpo mandibular y parasinfisaria. RESULTADOS: Las radiografías de los grupos de fractura mandibular fueron comparadas con el grupo de oclusión normal para analizar el espacio de las vías respiratorias superiores y los cambios de posición hioidea. Diferentes tipos de fracturas tienen diferentes efectos sobre el espacio de las vías respiratorias superiores. La fractura de cuerpo mandibular bilateral y la fractura de parasinfisaria tienen una influencia significativa en los espacios de las vías respiratorias orofaríngea y laringofaríngea inferiores, con serios obstáculos restringiendo severamente la función respiratoria de los pacientes. CONCLUSIONES: Las fracturas en diferentes partes de la estructura mandibular se hallan estrechamente vinculadas a las vías respiratorias superiores y a la posición hioidea.

ABSTRACT

Las metástasis bucales constituyen un grupo de baja frecuencia pero de gran importancia en particular por su localización. Según datos bibliográficos internacionales, representan del 1 por ciento al 8 por ciento de todas las neoplasias malignas bucales. Pueden localizarse tanto en los tejidos blandos como en los huesos maxilares (84 por ciento) prevaleciendo en la mandíbula, principalmente en el área molar, seguida del sector premolar. La localización condilar es rara. En los últimos 55 años sólo han sido reportados 48 casos. Dado que no existen patrones clínicos ni radiográficos que permitan caracterizar las lesiones, estas patologías suelen en un principio ser tratadas erróneamente como desordenes propios de la articulación temporo mandibular (ATM).Se presenta un caso clínico de a una paciente de sexo femenino de 36 años con antecedentes de adenocarcinoma de recto que presenta una metástasis en cóndilo bajo la apariencia clínica de un cuadro de disfunción de la ATM. Corresponde al tercer caso reportado en la literatura.


Oral metastases are a group of low-frequency lesions but important particularly because of its location. According to international bibliographic data represent 1% to 8% of oral malignancies. They can be located both in soft tissues and in the jaws (84%). Prevails in the mandible, mainly in the molar area, followed by the premolar region. The condylar location is extremely rare. Since the clinical and radiographic features are not characteristic, these lesions are often erroneously treated initially as temporomandibular joint (TMJ) disorders.In the last 55 years only 48 cases have been reported. We present a 36-years-old female patient with antecedents of rectal adenocarcinoma treated two years ago, having a metastasis in the mandibular condyle with clinical appearance of TMJ dysfunction.This is the third case reported in the literature.
