RESUMO
Introdução: a região orbitária é bastante suscetível a fraturas, devido a sua posição exposta e a ossos frágeis. As fraturas do tipo blow-out caracterizam-se pela fratura do assoalho orbitário com ou sem herniação de conteúdo para o seio maxilar, gerando consequências funcionais e estéticas. Relato do caso: paciente do sexo feminino, 48 anos de idade, vítima de queda da própria altura, compareceu ao Hospital Geral do Estado da Bahia com queixa de diplopia, apresentando fratura de assoalho de órbita direita. Foi programada uma abordagem transconjuntival e instalação de tela de titânio para reconstrução. Na alta hospitalar, a paciente negou diplopia, não apresentando prejuízos funcionais ou estéticos. Conclusão: o acesso transconjuntival possibilita uma adequada exposição do assoalho de órbita, para colocação de telas, deixando uma cicatriz imperceptível na conjuntiva. Apesar das vantagens, este acesso cirúrgico apresenta maior complexidade técnica, sendo pouco realizado pelos cirurgiões
Introduction: the orbital region is very susceptible to fractures due to its exposed position and fragile bones. Blow-out fractures are characterized by fractures of the orbital floor with or without herniation of contents to the maxillary sinus, generating functional and aesthetic consequences. Case report: a 48-year-old female patient, victim of a fall from her height, presented to the General Hospital of the State of Bahia complaining of diplopia, presenting with a fracture of the floor of the right orbit. A transconjunctival approach and installation of titanium mesh for reconstruction were scheduled. At hospital discharge, the patient denied diplopia, with no functional or aesthetic impairments. Conclusion: the transconjunctival approach allows adequate exposure of the orbital floor for mesh placement, leaving an imperceptible scar on the conjunctiva. Despite the advantages, this surgical approach presents greater technical complexity and is rarely performed by surgeons.

ABSTRACT Purpose: This study aimed to evaluate the mechanisms of injury and types of orbital fractures and their relation to concurrent commotio retinae. Methods: This retrospective study evaluated the records of patients with orbital fractures whose diagnoses had been confirmed by computer tomography between July 2017 and September 2019. Patient demographics, the circumstances of injury, ophthalmic examination results, and radiological findings were tabulated. Statistical analysis of the data used two-tailed student's t-tests, chi-squared tests, and odds ratio calculations. Statistical significance was set at p<0.05. Results: Of the 204 patients with orbital fractures included in this study, 154 (75.5%) were male. The mean age was 42.1 years. Orbital fractures involving one orbital wall (58.8%) were more common than those affecting multiple walls (41.2%). The majority of fractures affected the inferior wall (60.3%), with the medial walls being the next most frequently affected (19.6%). The most common cause of injury was assault (59.3%), and the second most common was falls (24%). Commotio retinae was observed in 20.1% of orbital fracture cases and was most associated with injuries caused by assault (OR=5.22, p<0.001) and least associated with those caused by falls (OR=0.06, p<0.001). Eye movement restrictions were more common in central than peripheral commotio (OR=3.79, p=0.015) and with medial wall fractures than fractures to other orbital walls (OR=7.16, p<0.001). The odds of commotio were not found to be higher in patients with multi-walled orbital fractures than in those with single-walled fractures (p=0.967). Conclusions: In the study population, assault was the most common cause of orbital fractures and resulted in commotio retinae than other causes. Ophthalmologists should be aware of the likelihood of commotio retinae in patients with orbital fractures resulting from assault, regardless of the extent of the patient's injuries.
RESUMO Objetivo: Este estudo visou avaliar os mecanismos da lesão e os tipos de fraturas orbitárias e sua relação com commotio retinae simultânea. Métodos: Este estudo retrospectivo avaliou registros de pacientes com fraturas orbitárias cujos diagnósticos foram confirmados por tomografia computadorizada entre julho de 2017 e setembro de 2019. Foram registrados os dados demográficos, circunstâncias da lesão, os resultados do exame oftalmológico e achados radiológicos. A análise estatística dos dados usou os testes de t-Student bicaudal, qui-quadrado e cálculos de odds ratio. O significado estatístico foi fixada em p<0,05. Resultados: Dos 204 pacientes com fraturas orbitárias incluídos neste estudo, 154 (75,5%) eram sexo masculino (75,5%). A média de idade foi de 42,1 anos. As fraturas orbitárias envolvendo uma parede orbital (58,8%) foram mais comuns do que as que acometeram várias paredes (41,2%). A maioria das fraturas acometeu a parede inferior (60,3%), sendo as paredes mediais as próximas mais frequentemente afetadas (19,6%). A causda mais comum de lesão foi agressão (59,3%), e a segunda mais comum foi queda (24%). A commotio retinae foi observada em 20,1% dos casos de fratura orbital e foi mais associada a lesões causadas por agressão (OR=5,22, p<0,001) e menos associada com aquelas causadas por quedas (OR=0,06, p<0,001). As restrições de movimentos oculares eram mais comuns na comoção central do que na periférica (OR=3,79, p=0,015) e com fraturas da parede medial do que com fraturas de outras paredes orbitais (OR=7,16, p<0,001). As chances de comoção não foram maiores em pacientes com fraturas orbitais de paredes múltiplas do que naqueles com fraturas de parede simples (p=0,967). Conclusões: Na população do estudo, a agressão foi a causa mais comum de fraturas orbitais e resultou em commotio retinae mais grave do que qualquer outra causa. Os oftalmologistas devem estar cientes da probabilidade de commotio retinae em pacientes com fraturas orbitais resultantes de agressão, independentemente da extensão das lesões do paciente.

Objetivo: Discutir o tratamento cirúrgico secundário de uma fratura de órbita tipo Blow-Out, explorando os desafios e limitações relacionados a este padrão de fratura. Relato de Caso: Paciente sexo masculino, 50 anos, ASA I relatando histórico de agressão física e quatro cirurgias prévias em região orbitária direita. Clinicamente foram observados sinais como enoftalmo, hipoftalmo, encurtamento da pálpebra inferior, dificuldade de oclusão palpebral, entrópio, hiperemia em conjuntiva, além de presença de secreção purulenta, todos em região orbitária à direita. Diante do exposto, uma nova intervenção cirúrgica foi proposta pela Cirurgia e Traumatologia Bucomaxilofacial, na tentativa corrigir alguns problemas listados, além de encaminhamento a outras especialidades. Encontra-se em acompanhamento de um ano, com boa evolução. Conclusão: O tratamento de fraturas orbitárias é um dos mais desafiadores, especialmente quando se trata sequelas. A definição pelo melhor momento para realização destes procedimentos não é um consenso, sendo necessário uma avaliação clínica criteriosa. Apesar da utilização dos enxertos autógenos ser amplamente recomendada, os materiais aloplásticos vem se tornando a primeira escolha para tratamento das correções secundárias pelas diversas vantagens oferecidas.

RESUMEN Andrés Avelino Cáceres (1836-1923) fue un destacado político y militar peruano que ocupó la presidencia en dos periodos y lideró al ejército peruano durante la Guerra del Pacífico, por lo que es considerado un héroe nacional. Al inicio de su carrera militar, durante el sitio a la ciudad de Arequipa en 1858, sufrió una lesión ocular cuya cicatriz se observa en las fotografías que se le tomaron posteriormente a lo largo de su vida, lo que hizo que fuera apodado "El Tuerto" aunque al parecer su agudeza visual estuvo indemne. En este trabajo describiremos las circunstancias en las que se produjo la lesión oftálmica de Andrés Avelino Cáceres, las secuelas que pudo tener este traumatismo oftálmico y el tratamiento médico que pudo haber recibido, en base al propio relato del héroe y a las imágenes suyas que se conservan.
ABSTRACT Andrés Avelino Cáceres (1836-1923) was a prominent Peruvian politician and military man who held the presidency for two terms and led the Peruvian army during the Pacific War, for which he is considered a national hero. At the beginning of his military career, during the siege of the city of Arequipa in 1856, he suffered an eye injury whose scar can be seen in the photographs that were taken of him later throughout his life, which led to him being nicknamed "El Tuerto". We will describe the circumstances in which the ophthalmic injury of Andrés Avelino Cáceres occurred, the consequences that this ophthalmic trauma could have had and the treatment he could have received, based on the hero's own story and the images of him that are preserved.
RESUMO
Objetivo: relatar um caso clínico, embasando os aspectos relativos à técnica cirúrgica transconjutival com cantotomia lateral como tratamento para fratura de COZM. Relato de caso: Paciente, gênero masculino, compareceu ao Serviço de Cirurgia e Traumatologia Bucomaxilofacial do Hospital Geral do Estado (HGE), vítima de acidente motociclístico, apresentando distopia ocular, degrau ósseo em rebordo infraorbitário direito, perda de projeção malar direita, abertura bucal limitada com desvio ipsilateral e distopia oclusal com sinais sugestivos de fratura do complexo-orbito-zigomático-maxilar direito, juntamente com fratura complexa da mandíbula. A abordagem cirúrgica para acessar o COZM contou com a técnica de incisão transconjuntival com cantotomia lateral para uma melhor visualização dos cotos ósseos fraturados. Considerações finais: a escolha por esse tipo de acesso resultou em uma abordagem cirúrgica bem-sucedida, proporcionando segurança na visualização do campo cirúrgico para posterior reabilitação do paciente, estabelecendo uma devolutiva estética e funcional, cicatriz imperceptível e consequentemente um melhor prognóstico para o paciente.(AU)

Objective:To investigate influencing factors of persistent diplopia after orbital floor blowout fracture reconstruction surgery.Methods:A case control study was conducted.Data of 146 eyes of 146 orbital floor blowout fracture patients with diplopia occurring 1 day after operation were collected in Henan Eye Hospital from July 2011 to July 2020.The patients were divided into two groups, persistent diplopia group (14 cases 14 eyes) and disappeared diplopia group (132 cases 132 eyes), according to the persistence of diplopia in the follow-up.Differences in sex, right or left eye, age, preoperative course of disease, preoperative intraorbital soft tissue hernia, operation methods, operation approach, postoperative eyeball rotation exercise compliance, the number of eyes with postoperative inferior rectus muscle damage level were compared between the two groups to select factors with P<0.05 for multifactor logistic regression analysis.This study protocol adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[15]). Results:All eyes were successfully operated and no complications such as infection or dislocation of the orbital implant occurred in any of the eyes during the postoperative follow-up period.There were statistically significant differences in age, preoperative course of disease, preoperative intraorbital soft tissue hernia, operation methods, postoperative eyeball rotation exercise compliance and postoperative inferior rectus muscle injury between the two groups ( χ 2=9.443, P=0.002; χ 2=29.041, P<0.001; H=53.943, P<0.001; H=34.583, P<0.001; χ 2=46.041, P<0.001; H=101.438, P<0.001). The multiple logistic regression analysis indicated that the long preoperative course of disease ( OR=8.678, 95% CI=1.013-74.304, P=0.031), preoperative intraorbital soft tissue hernia (Severe: OR=32.963, 95% CI=7.647-142.084, P<0.001.Moderate: OR=11.852, 95% CI=2.679-52.436, P=0.001), and postoperative inferior rectus muscle injury (Severe: OR=511.000, 95% CI=42.815-6 110.808, P<0.001.Moderate: OR=132.000, 95% CI=12.442-1 400.458, P<0.001) were independent risk factors for postoperative persistent diplopia.Advanced operation methods (Individualized shaped titanium mesh method: OR=0.020, 95% CI=0.002-0.127, P<0.001.Manufacturers prefabricated titanium mesh method: OR=0.031, 95% CI=0.004-0.257, P=0.001), and the postoperative eyeball rotation exercise ( OR=0.015, 95% CI=0.001-0.197, P<0.001) were independent protective factors for postoperative persistent diplopia. Conclusions:Severe preoperative intraorbital soft tissue hernia and postoperative inferior rectus muscle injury are the main risk factors for persistent postoperative diplopia after orbital floor blowout fracture repair surgery.Shortening the preoperative course of disease, improving the operation methods, and enhancing postoperative ocular functional exercises may reduce the incidence of postoperative persistent diplopia.
RESUMO
Orbital fracture often leads to facial collapse, diplopia, enophthalmos, and even blindness. Traditional surgery relies on the experiences of physicians to achieve fracture reduction and orbital wall reconstruction, but the repair effect is not satisfactory. In recent years, with the development of digital technology, technologies such as computer-assisted surgery, 3D printing, surgical navigation systems, and intraoperative CT imaging have become increasingly widespread in the field of orbital reconstruction. Such techniques can avoid dependence on physicians′ experiences and make it easy for estimating and positioning the implantation sites, which subsequently contributes to better surgery efficiency and precise reconstruction of the orbit, improving aesthetics and visual function of patients. To this end, the authors reviewed the recent progress in application of digital technology for orbital fracture reconstruction, so as to provide reference and theoretical basis for clinical practice.
RESUMO
RESUMO Um em cada quatro pacientes acometidos por trauma maxilofacial terão concomitantemente fraturas da órbita e lesão ocular. Por isso, uma avaliação oftalmológica minuciosa é recomendada para todos os pacientes que sofrem um trauma de face. Alguns exames oftalmológicos logo após o trauma podem ser decisivos para a preservação da acuidade visual. Sujeitos com achados de exame físico de acuidade visual deficitárias, defeito pupilar aferente e imagens radiográficas com alta profundidade da fratura da órbita estão em maior risco de perda de visão e justificam preocupação específica para avaliação de lesão ocular. O objetivo deste estudo foi reunir as manifestações clínicas oftalmológicas prevalentes em pacientes acometidos por fraturas orbitárias, com o intuito de adquirir melhor perspectiva e entendimento acerca das consequências que a patologia traz ao indivíduo, no que tange à oftalmologia e aos tratamentos mais adequados. Trata-se de estudo de revisão integrativa, utilizando as bases de dados Pubmed®/Medline®, SciELO, Biblioteca Virtual em Saúde e Lilacs, com um vocabulário controlado segundo a estratégia de busca em cada uma das bases de dados bibliográficas, por meio dos termos "ophthalmologic complications", "prevalence", "orbital fracture", em estudos publicados de 2013 a 2023. A qualidade dos artigos foi avaliada usando o Study Quality Assessment Tool from the Department of Health and Human Services. Foram encontradas 46 referências, sendo 20 no Pubmed®/Medline®, 17 na SciELO, 9 na Biblioteca Virtual em Saúde e nenhuma na Lilacs. Após excluir referências duplicadas, foram selecionadas 44 referências para avaliação de elegibilidade. Após leitura dos títulos e resumos (n=44), 36 estudos foram excluídos pelas seguintes razões: artigos que não respondiam a nossa pergunta científica (n=11) e publicação superior a 10 anos (n=25). Identificaram-se, nos oito artigos selecionados, o objetivo do estudo, a população estudada o nível de evidência. Os oito estudos tiveram como objetivo analisar traumas orbitais com alterações funcionais significativas oculares e visuais pelo prejuízo ao tecido ósseo, nervoso, vascular e até parenquimatoso cerebral na região do assoalho e paredes de cavidades orbital. Dentre as manifestações clínicas oftalmológicas mais importantes, listam-se manifestação de enoftalmia, diplopia, hifema traumático, hemorragia retiniana, amaurose, quemose, neuropatia óptica traumática e hematoma retrobulbar. Considerando os oito estudos analisados, verificou-se a presença unânime de manifestações clínicas oftalmológicas na totalidade dos pacientes acometidos, sendo predominantes a baixa acuidade visual e o hifema. No que tange aos achados de menor prevalência, ao equipará-los às manifestações clínicas oftalmológicas mais encontradas, verifica-se que possuem como fator principal o estado transitório, concluindo-se que, mesmo com toda a gravidade do quadro de fratura orbitária, sua tendência é não deixar sequelas permanentes em grande partes dos casos, ainda que não seja nítida a relação estabelecida pela ausência de sequelas permanentes, especulando-se que essa ausência se deve à identificação do quadro e à intervenção adequada em tempo hábil.
ABSTRACT One in four patients affected by maxillofacial trauma will have concomitant orbital fractures and ocular injuries; therefore, an ophthalmological evaluation is recommended for all patients who have been affected by facial trauma. Some ophthalmological exams soon after the trauma can be decisive for the preservation of visual acuity. Patients with physical examination findings of poor visual acuity, afferent pupillary defect, radiographic images with high depth of orbital fracture, are at greater risk of vision loss and specific concern for evaluation of ocular injury. The objective of this study was to gather the prevalent ophthalmologic clinical manifestations in patients affected by orbital fractures, to achieve a better perspective and understanding about the consequences that the pathology brings to the individual regarding ophthalmology and the most appropriate treatments. This is an integrative review study, using the Pubmed®/Medline®, SciELO, Virtual Health Library and Lilacs databases, with a controlled vocabulary according to the search strategy in each of the bibliographic databases, using the terms "ophthalmologic complications", "prevalence", "orbital fracture", in studies published from 2013 to 2023. The quality of the articles was assessed using the Study Quality Assessment Tool from the Department of Health and Human Services. A total of 46 references were found, 20 in Pubmed®/Medline®, 17 in SciELO, 9 in the Virtual Health Library and none in Lilacs. After excluding duplicate references, 44 references were selected for eligibility assessment. After reading the titles and abstracts (n=44), 36 studies were excluded for the following reasons: articles that did not answer our scientific question (n=11) and publication over 10 years (n=25). In the eight selected articles, the objective of the study, the population studied, and the level of evidence were identified. The eight studies aimed to analyze orbital trauma with significant ocular and visual functional changes due to damage to bone, nerve, vascular, and even brain parenchymal tissue in the region of the floor and walls of orbital cavities. Among the most important ophthalmologic clinical manifestations, there are enophthalmos, diplopia, traumatic hyphema, retinal hemorrhage, amaurosis, chemosis, traumatic optic neuropathy and retrobulbar hematoma. Considering the eight studies analyzed, there was a unanimous presence of ophthalmological clinical manifestations in all affected patients, with low visual acuity and hyphema being predominant. Regarding the findings of lower prevalence, when equating them to the most common ophthalmologic clinical manifestations, they have as main factor the transient state, which can be concluded that, even with all the severity of the orbital fracture, its tendency is not to leave permanent sequelae in most cases, although the relationship established by the absence of permanent sequelae is not clear, speculating that this absence is due to the identification of the condition and the appropriate intervention in a timely manner.
RESUMO
El acceso transconjuntival asociado a cantotomía lateral ha sido utilizado para permitir una mejor visualización de fracturas del piso de órbita. Esta técnica ha reportado entropión, ectropión y complicaciones en el reposicionamiento tarsal. Para disminuir la morbilidad descrita, hemos complementado este acceso con otra técnica denominada "Cantolisis Lateral" la que ha sido ampliamente utilizada como tratamiento de urgencia para hematoma retrobulbar, con pocos reportes sobre su utilidad en el tratamiento de las fracturas orbitarias. Reportamos los resultados post operatorios de la aplicación de la técnica cantolisis lateral como complemento al acceso transconjuntival en una serie de casos de 16 pacientes. La distopía cantal y la discontinuidad del tarso inferior fueron las complicaciones más frecuentes reportadas. Sin embargo, los pacientes no se percataron de ellas. No se reportaron ectropión ni entropión.
Transconjunctival approach associated with lateral canthotomy has been used to allow a better visualization of orbital floor fractures. This technique has reported entropion, ectropion and complications in tarsal repositioning. To decrease the described morbidity, we have complemented this approach with another technique called "Lateral Cantholysis" which has been widely used as an emergency treatment for retrobulbar hematoma, with few reports about its usefulness in the treatment of orbital fractures. We report the postoperative results of the application of the lateral cantholysis technique as a complement to the transconjunctival approach in a case series of 16 patients. Cantal dystopia and lower tarsal discontinuity were the most frequent complications reported. However, patients were not aware of them. No ectropion or entropion were reported.

Introducción: las fracturas de pared de órbita pueden producir secuelas funcionales y estéticas. La indicación de reconstrucción quirúrgica, es indispensable para la recuperación de la motilidad y estética ocular. Los materiales reconstructivos más utilizados son los aloplásticos, como el titanio y el polietileno poroso de alta densidad (PPAD), el cual ha resultado exitoso en reconstrucción maxilofacial. El propósito de este estudio retrospectivo, es exponer los resultados tras el uso del PPAD en reconstrucciones orbitarias y sus posibles complicaciones. Materiales y métodos: se realizó una revisión retrospectiva de 22 pacientes donde se utilizó PPAD como material de reconstrucción en fracturas orbitarias. Se consideró para la indicación quirúrgica que el paciente presentara alguno de los siguientes signos: diplopía o síntomas vasovagales por atrapamiento muscular, restricciones en la motilidad ocular, enoftalmo mayor a 4mm. El material utilizado fue PPAD (Medpor Stryker®) puro en 17 casos y PPAD reforzado con una malla de titanio en el interior de su estructura (Medpor Titan Stryker®), en los 5 restantes. Resultados: se registraron 3 casos con complicaciones; ectropión, diplopía y ectropión con diplopía, los cuales todos fueron reversibles. No se registraron casos de infección ni complicaciones oftalmológicas postoperatoria. Discusión: los injertos autólogos fueron los primeros utilizados con resultados de compatibilidad y resistencia óptimos. El uso de PPAD como material de reconstrucción ha sido bien documentado con buenos resultados en términos de una baja incidencia de infección y óptima motilidad ocular a largo plazo.
Introduction: Orbital wall fractures can cause functional and aesthetic sequelae. When there is an indication for surgical reconstruction, this is essential for the recovery of ocular motility and aesthetics. The most commonly used reconstructive materials are alloplastics, such as titanium and porous high-density polyethylene (PPAD), which have been successful in maxillofacial reconstruction. The purpose of this retrospective study is to present the results and their possible complications in orbital reconstruction with PPAD. Materials and methods: a retrospective review of 22 patients in whom PPAD was used as reconstruction material for orbital fractures was performed. It was considered for the surgical indication that the patient presented any of the following signs: diplopia or vasovagal symptoms due to muscle entrapment, ocular motility restrictions, enophthalmos greater than 4mm. The material used was pure PPAD (Medpor Stryker®) in 17 cases, and PPAD reinforced with a titanium mesh inside its structure (Medpor Titan Stryker®), in the remaining 5. Results: 3 patients with complications were registered; ectropion, diplopia, and ectropion with diplopia, all of which were reversible. There were no cases of postoperative infection or ophthalmological complications. Discussion: Autologous grafts were the first used with optimal compatibility and resistance results. The use of PPAD as a reconstruction material has been well documented with good results in terms of a low incidence of infection and optimal long-term ocular motility
RESUMO
O objetivo deste estudo foi avaliar, por meio de tomografias computadorizadas, as alterações volumétricas pós-traumáticas, dos tecidos orbitários, no período préoperatório, pós-operatório imediato e após os primeiros 3 meses da cicatrização, correlacionando-as com a manutenção das complicações pós-traumáticas. Vinte e três pacientes com indicação cirúrgica para fraturas unilaterais de órbita foram avaliados clinicamente e por meio de tomografia computadorizada. A órbita oposta, não fraturada foi utilizada como controle. As complicações mais frequentes foram enoftalmo, diplopia e distopia. A alteração volumétrica tecidual nas órbitas fraturadas apresentou-se constante e com diferença estatística significante, com p< 0,0001. Não houve correlação estatística entre a diferença volumétrica do conteúdo orbitário nos 3 períodos e a manutenção das complicações pós-traumáticas, apresentando p= 0,1617. Semelhantemente, não houve correlação entre a área fraturada e a permanência das complicações. Conclui-se que o volume do conteúdo da cavidade orbitária não poderá ser utilizado como fator determinante para a permanência da complicação pós-traumática(AU)
The aim of this study was to evaluate through computed tomography, the posttraumatic volumetric alterations of the orbital tissues, in the preoperative period, immediate postoperative period, and after the first 3 months of healing, correlating them with the maintenance of the post-traumatic complications. Twenty-three patients with surgical indication for unilateral orbital fractures were evaluated clinically and by means of computed tomography. The opposite, unfractured orbit was used as a control. The most frequent complications were enophthalmos, diplopia and dystopia. The tissue volume change in the fractured orbits was constant and present statistically significant difference, with p< 0.0001. There was no statistical correlation between the volumetric difference of orbital content in the 3 periods and the maintenance of post-traumatic complications, with p= 0.1617. Similarly, there was no correlation between the fractured area and the permanence of complications. It is concluded that the volume of the orbital cavity content cannot be used as a determining factor for the permanence of the post-traumatic complication(AU)

@#AIM: To evaluate the clinical application of resorbable implants in orbital fracture repair surgery.<p>METHODS: A retrospective analysis of 48 eyes in 48 cases of orbital fracture, all patients were treated with resorbable implants for orbital fracture repair. During operations we exposed fully fracture defect range and returned the tissues that entered the paranasal sinus. A resorbable implant was trimmed to proper sizes according to the fracture defect range and fixed with 2 absorbable screws. The accuracy of plate positioning of the reconstructed orbit and the practicability of clinical use of resorbable implant were judged by the ophthalmic examination and computed tomography(CT)scan before and after operation. <p>RESULTS: All the patients completed the operation successfully and had no serious complications during or after surgery. All the patients had a good anatomical restoration by the postoperative CT scan. One year re-examination after operation, among 18 eyes with limitation of extraocular muscle movement(EOM)before operation 1 eye(6%)with limitation of EOM improved after surgery,17 eyes(94%)with limitation of EOM got cured. Among 30 cases with diplopia before operation 12 cases(40%)with diplopia improved after surgery, 18 cases(60%)with diplopia got cured. Among 32 eyes with enophthalmos before operation 10 eyes(31%)with enophthalmos improved after surgery, 22 eyes(69%)with enophthalmos get cured. Among 40 eyes with suborbital skin numbness before operation 33 eyes(82%)with suborbital skin numbness improved after surgery, 7 eyes(18%)with suborbital skin numbness got cured. Only one eye got lower eyelid entropion after surgery and was resolved by the second correction of entropion.<p>CONCLUSION: The resorbable implant can repair the fractures of orbital wall well. It is a better material of orbital fracture repairment.
RESUMO
@#Pediatric ocular trauma; though the number is small, can lead to a devastating lifetime impact due to its risk of amblyopia (if it occurs before the age of seven) and also loss of vision. We are reporting a case of a young 12-year-old-boy who was struck unintentionally by an arrow to the eye by another friend during sports activity. The arrow pierced the right eyebrow just below the orbital roof then perforated the globe from the superior orbit pointing downwards piercing the floor of the orbit fracturing the maxillary roof. Emergency scleral repair was done; however, there was no useful vision left. Arrow injury to the eye is a rare occurrence but leads to severe consequences given its high velocity and projectile in nature. The incidence is low and highly avoidable if precautionary measures are taken.
RESUMO
ABSTRACT Posterior fractures of the orbital floor are challenging, since an incomplete visualization of the defect through conventional surgical accesses may compromise the surgical outcome. The use of the endoscope as an auxiliary method during orbital reconstructions may be considered as a tool of considerable importance, mainly due to the visualization of the whole extension of fracture and adaptation of meshes or bone grafts. This study aims to report a clinical case of a patient diagnosed with extensive blowout fracture showing diplopy, enophthalmos, and ophthalmoplegia in supraversion, who underwent a subciliary approach combined with transantral video assisted surgery. There were no intercurrences on the procedure. Currently, patient has 1 year of follow up, with reestablished orbital function and architecture.
RESUMO As fraturas posteriores do assoalho orbital são desafiadoras, visto que a incompleta visualização do defeito por meio dos acessos cirúrgicos convencionais poderá comprometer o resultado cirúrgico. O uso do endoscópio como método auxiliar durante as reconstruções orbitais pode ser considerado uma ferramenta de grande importância principalmente para visualização de toda a extensão da fratura e adaptação das malhas ou enxertos ósseos. Este trabalho tem como objetivo relatar um caso clínico de um paciente diagnosticado com uma extensa fratura blowout apresentando clinicamente diplopia, enoftalmo e oftalmoplegia em supraversão, o qual foi submetido a tratamento através da abordagem subciliar combinada com a cirurgia vídeo-assistida transantral. O procedimento foi realizado sem intercorrências, estando o paciente com 1 ano de acompanhamento, com função e arquitetura orbital restabelecidos.

A região orbitária é bastante suscetível a traumas, visto que apresenta uma posição exposta, além de ser composta por ossos frágeis. Quando indicada, é preciso intervenção cirúrgica para preservar a função visual e harmonia facial do paciente. Os acessos transconjuntival e transcaruncular são descritos na literatura como formas seguras, rápidas, funcionais e esteticamente benéficas para a abordagem ao assoalho orbitário e lâmina papirácea. Sobre os materiais biocompatíveis utilizados, a placa de titânio é inabsorvível e permite fixação interna rígida, moldada às curvaturas naturais dos ossos, com baixo risco de infecção. As folhas de polietileno poroso são polímeros inertes e não absorvíveis que facilitam o crescimento de tecido e reduzem as chances de rejeição. Nesse relato de caso, evidencia-se paciente masculino, 28 anos, vítima de traumatismo facial após prática esportiva que apresentou fratura de assoalho e parede medial orbitária direita, com indicação de reconstrução orbitária com acessos transconjuntival e transcaruncular para fixação de placa de titânio em assoalho da órbita direita e de folhas de polietileno poroso em lâmina papirácea à direita, respectivamente (AU)
The orbital region is quite susceptible to trauma, since it has an exposed position, besides being com-posed of fragile bones. When indicated, surgical intervention is required to preserve the patient's visual function and facial harmony. Transconjunctival and transcaruncular accesses are described in the literatu-re as safe, fast, functional and with esthetic benefits for the approach to the orbital floor and papyraceous lamina. Among the biocompatible materials used, the titanium plate does not undergo resorption and allows rigid internal fixation, being shaped to the natural curvatures of the bones, with low risk of infec-tion. Porous polyethylene sheets are inert and nonabsorbable polymers that facilitate tissue growth an reduce the chances of rejection. In this case report, a 28-year-old male patient, a victim of facial trauma after sports practice presented a fracture of the floor and the right orbital medial wall, and orbital recons-truction was indicated with transconjunctival and transcaruncular accesses for fixation of titanium plate in the floor of the right orbit and porous polyethylene sheets in papyracea leaf on the right, respectively (AU)

RESUMO
BACKGROUND: To date, a variety of surgical approaches have been used to reconstruct the medial orbital wall fracture. Still however, there is still a controversy as to their applicability because of postoperative scars, injury of anatomical structures and limited visual fields. The purpose of this study was to introduce a useful additional medial subbrow approach for better reduction and securement more accurate implant pocket of medial orbital wall fracture with the subciliary technique. METHODS: We had performed our technique for a total of 14 patients with medial orbital wall fracture at our medical institution between January 2016 and July 2017. All fractures were operated through subciliary technique combined with the additional medial subbrow approach. They underwent subciliary approach accompanied by medial wall dissection using a Louisville elevator through the slit incision of the medial subbrow procedure. This facilitated visualization of the medial wall fracture site and helped to ensure a more accurate pocket for implant insertion. RESULTS: Postoperative outcomes showed sufficient coverage without displacement. Twelve cases of preoperative diplopia improved to two cases of postoperative diplopia. More than 2 mm enophthalmos was 14 cases preoperatively, improving to 0 case postoperatively. Without damage such as major vessels or extraocular muscles, enophthalmos was corrected and there was no restriction of eyeball motion. CONCLUSION: Our ancillary procedure was useful in dissecting the medial wall, and it was a safe method as to cause no significant complications in our clinical series. Also, there is an only nonvisible postoperative scar. Therefore, it is a recommendable surgical modality for medial orbital wall fracture.

BACKGROUND: The conventional surgical method for reconstructing orbital floor fractures involves restoration of orbital continuity by covering an onlay with a thin material under the periorbital region. However, in large orbital floor fractures, the implant after inserting is often dislocated, leading to malposition. This study aimed to propose a novel implanting method and compare it with existing methods. METHODS: Among patients who underwent surgery for large orbital floor fractures, 24 who underwent the conventional onlay implanting method were compared with 21 who underwent the novel γ implanting method that two implant sheets were stacked and bent to resemble the shape of the Greek alphabet γ. When inserting a γ-shaped implant, the posterior ledge of the orbital floor was placed between the two sheets and the bottom sheet was impacted onto the posterior wall of the maxilla to play a fixative role while the top sheet was placed above the residual orbital floor to support orbital contents. Wilcoxon signed-rank test and Mann-Whitney U test were used for data analyses. RESULTS: Compared to the conventional onlay method, the gamma method resulted in better restoration of orbital contents, better improvement of enophthalmos, and fewer revision surgeries. CONCLUSION: Achieving good surgical outcomes for extended orbital floor fractures is known to be difficult. However, better surgical outcomes could be obtained by using the novel implantation method of impacting a γ-shaped porous polyethylene posteriorly.

BACKGROUND: Neurosensory changes are frequently observed in the patients with mid-face fractures, and these symptoms are often caused by infraorbital nerve (ION) damage. Although ION damage is a relatively common phenomenon, there are no established and objective methods to evaluate it. The aim of this study was to test whether trigeminal somatosensory evoked potential (TSEP) could be used as a prognostic predictor of ION damage and TSEP testing was an objective method to evaluate ION injury. METHODS: In this prospective TSEP study, 48 patients with unilateral mid-face fracture (only unilateral blow out fracture and unilateral zygomaticomaxillary fracture were included) and potential ION damages were enrolled. Both sides of the face were examined with TSEP and the non-traumatized side of the face was used as control. We calculated the latency difference between the affected and the unaffected sides. RESULTS: Twenty-four patients recovered within 3 months, and 21 patients took more than 3 months to recover. The average latency difference between the affected side and unaffected side was 1.4 and 4.1 ms for the group that recovered within 3 months and the group that recovered after 3 months, respectively. CONCLUSION: Patients who suffered ION damage showed prolonged latency when examined using the TSEP test. TSEP is an effective tool for evaluation of nerve injury and predicting the recovery of patients with ION damage.
