ABSTRACT

Introducción: las fracturas de la órbita son comunes y difíciles de manejar. Objetivo: realizar una revisión bibliográfica sobre las consideraciones anatómicas, fisiopatología, diagnóstico, tratamiento y complicaciones de las fracturas orbitarias. Métodos: se realizó una revisión bibliográfica en septiembre de 2016. Se evaluaron revistas de impacto de Web of Sciencies (35 revistas). Se consultaron las bases de datos MEDLINE, PubMed y SciELO con los descriptores: orbital fracture, treatment, epidemiology. Se incluyeron artículos en idioma inglés y español de los últimos 5 años. Se obtuvieron 127 artículos. El estudio se circunscribió a 47. Análisis e integración de la información: la órbita presenta debilidad anatómica en el piso y la pared medial que provoca una mayor afectación por fracturas. Existen varias teorías que justifican su aparición. El diagnóstico se basa en los hallazgos clínicos, incluidos los oftalmológicos, y medios auxiliares de diagnóstico; lo cual permite escoger la modalidad terapéutica y evitar complicaciones. Conclusiones: basados en el dominio de la anatomía y los métodos diagnósticos, la gestión de estas lesiones ha cambiado poco en los últimos años. Sin embargo, los avances en las imágenes orbitales, la introducción de sistemas de navegación intraoperatoria, mejores indicaciones quirúrgicas y diseños de implantes han llevado a una reevaluación del enfoque terapéutico de las fracturas orbitarias(AU)


Introduction: fractures of the orbit are common and difficult to manage. Objective: to carry out a bibliographic review on anatomical considerations, physiopathology, diagnosis, treatment and complications of orbital fractures. Methods: abibliographic review was carried out in September 2016. Journals of impact in the Web of Sciences (35 journals) were evaluated. The databases MedLine, PubMed and ScieELO were consulted with the descriptors: orbital fracture, treatment, and epidemiology. Articles in English and Spanish language of the last 5 years were included. 127 articles were obtained. The study was circumscribed to 47. Analysis and integration of information: the orbit presents anatomical weakness in the floor and the medial wall, which causes greater affectation due to fractures. There are several theories that justify its onset. The diagnosis is based on clinical findings, including ophthalmological findings, and diagnostic aids, which allows choosing the therapeutic modality and avoiding complications. Conclusions: based on the mastery of anatomic and diagnostic methods, the management of these lesions has changed little in recent years. However, advances in orbital imaging, the introduction of intraoperative navigation systems, better surgical indications and implant designs have led to a reassessment of the therapeutic approach to orbital fractures(AU)

ABSTRACT

Introdução: A reconstrução dos defeitos no assoalho orbital após fraturas constitui um desafio ao cirurgião plástico, pois além da expectativa estética e reconstrutora do paciente, cabe o tratamento de possíveis complicações funcionais, como diplopia e parestesias faciais. O objetivo é demonstrar uma série de casos utilizando cartilagem auricular conchal para reposição volumétrica orbital e estrutural do assoalho. Métodos: Foram avaliados 24 pacientes, operados pelo autor deste trabalho no período de 2013 a 2016, por motivo de fraturas de assoalho orbital pura (blow-out) ou impura (conjugadas a lesões de margem orbital, como zigoma e maxila). A técnica de estruturação do assoalho utilizou enxerto cartilaginoso autólogo conchal em todos os casos. Os pacientes foram catalogados quanto à presença de queixas pré-operatórias, como parestesia e diplopia, e sintomas, como enoftalmia, assim como resultados pós-operatórios. Resultados: A presença de lesões concomitantes como fratura de complexo zigomático e fratura maxilar pode influenciar no sucesso da reconstrução, assim como as fraturas com maior área de descontinuidade no assoalho orbital. Poucos pacientes apresentaram queixas pós-operatórias e somente dois casos (9,2%) necessitaram de nova abordagem cirúrgica. Conclusão: A cartilagem conchal auricular autóloga é um material adequado à reconstrução de defeitos no assoalho orbital pós-fratura, apresentando como vantagens a fácil obtenção, baixa morbidade, cicatriz inconspícua, excelente adaptação ao formato do assoalho da órbita e consequente reposição volumétrica.


Introduction: The reconstruction of defects in the orbital floor after fractures poses a challenge to the plastic surgeon because besides the patient's aesthetic and reconstructive expectations, possible functional complications such as diplopia and facial paresthesia must be treated. This study aimed at reporting a series of cases in which conchal auricular cartilage was used for volumetric orbital and structural replacement of the floor. Methods: Twenty-four patients, with surgery performed by the author, between 2013 and 2016, for pure (blow-out) or impure (conjugated to orbital margin injuries, such as zygoma and maxilla) orbital floor fractures, were evaluated. The repair technique involved autologous conchal cartilage graft in all cases. Patients were classified for the presence of preoperative complaints, including paresthesia and diplopia, and symptoms such as enophthalmia, as well as postoperative outcomes. Results: The existence of concomitant lesions, such as zygomatic complex and maxillary fracture, as well as fractures with greater discontinuity in the orbital floor, may influence the success of reconstruction. Few patients exhibited postoperative complaints and only two (9.2%) required a new surgical approach. Conclusion: Autologous conchal auricular cartilage is a suitable material for reconstruction of defects in the post-fracture orbital floor, possessing various advantages, including ease of attainment, low morbidity, inconspicuous scar, and excellent adaptation to the shape of the orbital floor and consequent volumetric replacement.

ABSTRACT

This report describes the only case in the literature of globe luxation due to traumatic cerebrospinal fluid fistula to the orbit caused by fire gun with ocular globe maintenance. E.N., female, white, 7 months, admitted with left orbitocranial injury by fire gun. Ocular globe luxation was detected with complete ocular motility restriction and absence of pupillary reflex in the left orbit. Computed tomography showed fracture of the medial orbital wall; bone fragments near the apex of the orbit and a stretched optic nerve. Surgical exploration was performed, showing liquor fistula through the ethmoid-sphenoid wall that was blocked with sponge (Gelfoam®) plus organic glue in the left orbit posterior wall, with immediate resolution of the proptosis and ocular integrity maintenance. Although controversial, maintenance of the ocular globe instead of enucleation was performed due to the integrity of the globe in this case. Despite the blindness, we considered the result to the proposed treatment excellent, once the maintenance of the ocular globe provides a good appearance and will contribute to an adequate facial bone development.


O presente estudo apresenta o único caso de luxação de globo ocular devido fístula liquórica traumática em vítima de trauma órbito-cerebral por projétil de arma de fogo com a preservação do globo ocular. E.N., feminino, branca, 7 meses, admitida com ferimento por projétil de arma de fogo em região órbito-craniana esquerda. Apresentava luxação de globo ocular esquerdo com restrição completa da motilidade ocular e reflexo fotomotor ausente à esquerda. À tomografia: fraturas da parede medial da órbita; fragmentos ósseos próximos ao ápice da órbita. Realizou-se exploração cirúrgica, evidenciando-se fístula liquórica através de fratura etmoido-esfenoidal a qual foi tamponada com esponja (Gelfoam®) e cola orgânica na parte posterior da parede medial da órbita esquerda, com regressão imediata da luxação do globo ocular, sendo o mesmo mantido íntegro. Embora controversa na literatura, optou-se pela preservação do globo ocular à enucleação, visto que o mesmo estava íntegro. Apesar da cegueira, consideramos um excelente resultado ao tratamento proposto, tendo em vista que a preservação do globo ocular provém uma boa aparência, favorecendo também o desenvolvimento ósseo da face.

ABSTRACT

OBJECTIVE: The purpose of this study was to perform a clinical retrospective analysis of the etiology, incidence and treatment of selected oral and maxillofacial injuries in Brazilian children and adolescents. MATERIAL AND METHODS: This study was conducted during a 14-year period between 1986 and 2000. All patients were admitted to Hospital XV in the city of Curitiba, State of Paraná. Age, gender, monthly distribution, etiology, soft injuries, associated injuries, site of fractures and methods of treatment were reviewed. RESULTS: Of the total of 350 patients of all ages treated for facial injuries, 29.42% were within the age range of the study (0 to 18 years). Mean age was 10.61. Of the patients, 63.1% were male. The most common cause of injury was accidental falls (37.87%), followed by bicycle and motorcycle accidents (21.36%). Of the 103 patients, 88.34% had single injuries. Mandibular fractures were the most common and the condylar region was particularly affected. CONCLUSIONS: Facial trauma is a relatively common occurrence in children. The study indicates that fractures in children and adolescents differ quite considerably from an adult population.

ABSTRACT

Children aged 6-15 years old experience more injuries to their teeth and the injuries sustained are more serious as evidenced by a higher percentage of luxations, avulsions, fractures and dislocations. The mandible is the most frequently fractured facial bone and mandibular alveolar injuries have been reported to range between 8.1-50.6%. Those with mandibular or midface fractures have a higher incidence of associated chest, extremity, abdomen and cervical spine injuries. The growing patient with facial injuries presents the clinician with a series of thought-provoking circumstances. Dentoalveolar and mandibular injuries are especially important to understand because of the potential complications related to tooth eruption, alveolar development, occlusion and facial growth. However, the principles involved in the treatment for children need to be modified by certain anatomical, physiological and psychological factors specifically related to childhood. This case report documents the trauma, management and follow-up care of an 11-year-old boy who sustained undisplaced infraorbital, nasal fractures and mandibular dentoalveolar fracture along with other associated injuries of the extremities.

ABSTRACT

As fraturas orbitárias blowout são aquelas que acometem exclusivamente o assoalho e/ou a parede medial da órbita. O diagnóstico destas fraturas baseia-se em exame físico e em exames imaginológicos. No exame físico, sinais e sintomas, como equimose periorbitária, limitação de movimentos oculares, diplopia e enoftalmia,podem estar presentes. A tomografia computadorizada é o exame mais eficiente para o diagnóstico dessas fraturas. O tratamento deve ser realizado através da reconstrução das paredes orbitárias fraturadas combiomateriais autógenos, homógenos, heterógenos ou materiais aloplásticos. Neste trabalho, serão apresentados dois casos clínicos de fraturas blowout, tratadas com telas de titânio. Esses materiais mostraram-se eficientes, apresentando bons resultados em relação à capacidade de reconstrução do assoalho orbitário e de suporte ao conteúdo do globo ocular.

ABSTRACT

Las fracturas orbitarias se presentan cerca del 70 por ciento de traumas faciales; se clasifican en dos grupos: las "fracturas externas" que involucran desunión directa del borde orbitario e incluye las fracturas naso-orbitarias. El segundo grupo llamado "fracturas internas" o fracturas de estallamiento, en las cuales una o más paredes orbitarias son indirectamente rotas. Pueden ser comminutas y podrían involucrar tanto al borde y paredes de la órbita. Cualquier porción de la órbita puede ser involucrada en este tipo de fracturas siendo las de la pared interna y el piso son de mayor importancia oftalmológica. Las fracturas más comunes son las nasales y las fracturas de estallamiento orbitario. El fracaso para reconocer y tratar mínimas fracturas usualmente no conducen a complicaciones...

ABSTRACT

Se analiza retrospectivamente la evolución clínica de 26 pacientes con fractura del esternón (FE) atendidos en un período de cinco años, en el Hospital del Trabajador de Santiago. Ellos representan el 2,7 por ciento de 957 traumatismos torácicos atendidos en el período de 1993-1998. Se trata de 22 hombres y 4 mujeres, con edad promedio 44 años. El accidente vehicular fue la causa más frecuente y el 81,8 por ciento llevaba cinturón de seguridad. En 13 casos la FE fue una lesión aislada y en los restantes se asoció a otras fracturas o lesiones torácicas. El 92 por ciento de las fracturas se localizó en el cuerpo esternal y en la mitad de los casos no se observó desplazamiento. En dos pacientes (8,7 por ciento) se diagnosticó contusión miocárdica y no hubo lesión de grandes vasos. Ningún paciente requirió estabilización quirúrgica de la fractura. La evolución de los pacientes con fractura aislada fue benigna, con una hospitalización promedio de 3,2 días. En esta serie no hubo mortalidad

ABSTRACT

En el presente trabajo se describe una fractura compleja de tercio medio de cara: Le Fort II más fracturas unilaterales izquierdas: Le Fort III, de malar, de arco cigomático y parcial de maxilar superior tipo "Bassereau". El plan de tratamiento es cruento mixto: osteosíntesis a placa y suspensión esquelética interna. Se realiza la reducción del desplazamiento sufrido por el tercio medio y la fijación del mismo por la ligadura de Adams, conjuntamente con la osteosíntesis a placa de las fracturas frontomalar e infraorbitaria izquierda. La fijación esquelética primaria es cráneomaxilar, la cual se transforma en cráneomandibular por 15 días al incorporar el maxilar inferior a la suspensión alámbrica con el fin de un mayor reposo, estabilización y mantenimiento de la oclusión "bout a bout" lograda durante la reducción. Se observa en (a) la esquematización del traumatismo del enfermo. En (b) todos los métodos de fijación utilizados: placas, arcos y suspensiones alámbricas

ABSTRACT

Fraturas do osso malar e de órbitas, frequentes em acidentes da vida moderna, foram estudadas em 156 pacientes, a maioria dos quais eram homens, entre 20 a 40 anos, vítimas de acidentes automobilísticos, quedas e agressöes. Dificuldade em diagnosticar fraturas que apresentam poucas evidências clínicas säo comentadas e traçam-se consideraçöes sobre os sinais, sintomas e alteraçöes. Para isto, orienta-se para a exploraçäo minuciosa de qualquer evidência de fratura. Devido a frequentes lesöes oftalmológicas associadas, é aconselhado o exame oftalmológico sistemático. No tratamento foram utilizadas tanto técnica conservadora, com uso de gancho, quanto técnica cirúrgica, usando osteossíntese com fio de aço. Säo comentados aspectos das diversas terapêuticas utilizadas
