ABSTRACT

La región orbitaria representa una unidad estética funcional muy importante en la región facial. Se presenta un trabajo retrospectivo de un período de 20 años (2000-2020) de actividad pública-privada en el tratamiento de patología tumoral y traumática de la región orbitaria. Analizamos en 580 casos operados, 184 oncológicos y 396 traumáticos, diferentes aspectos comunes que intervienen en el tratamiento reconstructivo de la región: abordajes, técnicas quirúrgicas, consideraciones anatomofuncionales, principios básicos en cirugía maxilofacial orbitaria y complicaciones, resaltando la importancia del manejo correcto de los tejidos regionales en su reconstrucción. La mejor posibilidad para el paciente de lograr un buen resultado es con una operación primaria correcta. Sus complicaciones son de difícil tratamiento


The orbital region represents a very important functional aesthetic unit in the facial region. A retrospective study of a 20-year period (2000- 2020) of public-private activity in the treatment of tumor and traumatic pathology of the orbital region is presented. We analyzed in 580 operated cases, 184 oncological and 396 traumatic, different common aspects involved in the reconstructive treatment of the region: approaches, surgical techniques, anatomofunctional considerations, basic principles in orbital maxillofacial surgery and complications, highlighting the importance of the correct management of regional tissues in their reconstruction. The best possibility for the patient to achieve a good result is with a correct primary operation. Its complications are difficult to treat

ABSTRACT

La celulitis orbitaria es una patología grave que está asociada con sinusitis paranasal. Éstas suelen presentar edema periorbitario, dolor, y movimiento extraocular restringido. La mayoría de los casos presentan pronóstico favorable, asociado a terapia antibiótica o drenaje quirúrgico. Las celulitis de origen odontogénico representan 2 a 5 % de todos los casos; se caracterizan por una diseminación del proceso infeccioso desde los ápices de las raíces, infectando al seno maxilar, llegando a la órbita a través de la fisura orbitaria inferior o a través de un defecto en el piso de la órbita. En el presente estudio se reporta el caso de un paciente masculino de 28 años que consulta por aumento de volumen periorbitario izquierdo con 4 días de evolución, posterior a exodoncia de segundo molar superior izquierdo. Al examen extraoral presenta aumento de volumen izquierdo con eritema periorbitario, proptosis ocular ipsilateral con visión conservada, y salida de líquido purulento por fosa nasal izquierda. En los exámenes de laboratorio e imagenológicos se pesquisa compromiso de seno maxilar, etmoidal y esfenoidal, decidiendo su hospitalización y manejo quirúrgico en tres tiempos operatorios, los cuales permiten acceso a pared anterior del seno maxilar y a espacio pterigoideo. Dentro de los diagnósticos de celulitis orbitaria pueden incluir reacciones alérgicas, conjuntivitis o herpes. Se excluyeron los diagnósticos mencionados debido a que no se observaron alteraciones dermocutáneas periorbitarias. Por el contrario, el compromiso unilateral, movimiento ocular alterado y doloroso indica que el cuadro abarcaba espacios profundos. La infección de senos paranasales posterior a una exodoncia es una complicación poco frecuente. Un diagnóstico temprano adecuado disminuye la morbilidad y mortalidad de esta condición. Debemos estar alertas a complicaciones posteriores en procedimientos realizados, tener conocimiento en diagnóstico y manejo de posibles evoluciones tórpidas en pacientes.


Orbital cellulitis is a serious pathology that is associated with paranasal sinusitis. These medical conditions usually present with periorbital edema, pain, and restricted extraocular movement. Most cases have a favorable prognosis, associated with antibiotic therapy or surgical drainage. Cellulitis of odontogenic origin represents 2 to 5 % of all cases. They are characterized by a spread of the infectious process from the apices of the roots, infecting the maxillary sinus, reaching the orbit through the inferior orbital fissure or through a defect in the floor of the orbit. The present study reports the case of a 28-year-old male patient, who consulted for a volume increase in left periorbital volume with 4 days of evolution, after extraction of the upper left second molar. Extraoral examination showed left volume increase with periorbital erythema, ipsilateral ocular proptosis with preserved vision, and discharge of purulent fluid from the left nostril. The laboratory and imaging tests showed compromise of the maxillary, ethmoid and sphenoid sinus deciding on hospitalization and surgical management in three operative times, which allow access to the anterior wall of the maxillary sinus and the pterygoid space. Diagnoses of orbital cellulitis may include allergic reactions, conjunctivitis, or herpes. These diagnoses were excluded because no periorbital dermocutaneous alterations were observed. In contrast, unilateral involvement, impaired eye movement, and pain indicate that the condition involved deep spaces. Paranasal sinus infection after tooth extraction is a rare complication. An early diagnosis adequately decreases the morbidity and mortality of this condition. We must be alert to subsequent complications in procedures performed, have knowledge in diagnosis and management of possible torpid evolutions in patients.

ABSTRACT

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.

ABSTRACT

ABSTRACT A 97-year-old female presented with spontaneous acute-onset palpebral hyperemia and edema of the right eye that had progressively worsen over the previous three days. These signs did not suggest possible carotid-cavernous fistula until a second examination 72 h later, during which the patient exhibited significant progression. Despite embolization, the patient exhibited sustained corneal edema, clots, and turbidity in the aqueous humor, which resulted in permanent visual loss. A greater level of clinical suspicion for possible carotid-cavernous fistula is warranted on initial presentation of palpebral hyperemia and edema to prevent possible irreversible vision loss.


RESUMO O objetivo deste relato é apresentar o caso de uma paciente de 97 anos com início agudo e espontâneo de hiperemia e edema palpebral. Estes sinais não levaram a uma suspeita diagnóstica de fístula carótido-cavernosa até um segundo momento, quando a paciente apresentou progressão importante do quadro clínico. Apesar da realização de tratamento efetivo com embolização da fístula, a paciente manteve alterações oculares como edema de córnea, coágulos e turvação no humor aquoso, e manteve perda visual definitiva.

ABSTRACT

ABSTRACT We report the case of a 46-year-old diabetic man receiving treatment for rhino-orbital-cerebral mucormycosis with liposomal amphotericin B and surgical debridement. The patient's condition worsened clinically, accompanied by the loss of ocular motility and a visual acuity of absence of light perception. Radiological extension of the infection was evidenced, with invasion of the cavernous sinus. Based on ophthalmological findings, exenteration (a potentially disfiguring procedure) was indicated, but we opted for wide surgical debridement and administration of amphotericin B via intraconal catheter. Clinical improvement and resolution of inflammation occurred after 2 weeks of treatment. Thus, rhino-orbital-cerebral mucormycosis was effectively controlled through intraconal administration of amphotericin B, while avoiding exenteration. The intervention should be considered as an adjuvant treatment in selected rhino-orbital-cerebral mucormycosis cases before attempting exenteration.


RESUMO Os autores relatam o caso de um homem diabético de 46 anos de idade em tratamento para mucormicose rino-orbital-cerebral com anfotericina B lipossomal e desbridamento cirúrgico. Piora clínica foi observada, com acometimento de motilidade ocular e acuidade visual de ausência de percepção luminosa, sendo evidenciada extensão radiológica da infecção, com invasão do seio cavernoso. Com base nos achados oftalmológicos, uma exenteração, procedimento potencialmente desfigurante, foi indicada, mas optamos por realizar amplo desbridamento cirúrgico e administração intraconal de anfotericina B por cateter. Melhora clínica e resolução da inflamação ocorreram após duas semanas de tratamento. Dessa forma, a mucormicose rino-orbital-cerebral foi efetivamente controlada com a administração intraconal de anfotericina B, evitando a exenteração. A intervenção deve ser considerada como um tratamento adjuvante em casos selecionados de mucormicose rino-orbital-cerebral antes que a exenteração seja realizada.

ABSTRACT

RESUMEN: La reconstrucción de las paredes orbitarias fracturadas es compleja debido a la gran cantidad de parámetros volumétricos que posee. Una restitución inadecuada de ellas habitualmente está asociada a secuelas postquirúrgicas en el paciente. El contar con herramientas que optimicen la restitución de la forma anatómica de la órbita en su reconstrucción es de vital importancia, y la utilización de nuevas tecnologías ha permitido mejorar los resultados quirúrgicos, tanto anatómicos como funcionales. El objetivo de este artículo es mostrar dos herramientas quirúrgicas que permiten optimizar los resultados terapéuticos en pacientes con fractura de órbita, que son el modelo estereolitográfico con imagen en espejo y la tomografía computada intraoperatoria. Se presentan las características de estas herramientas, su utilización en tres casos de pacientes con fractura orbitaria y los resultados obtenidos en el post operatorio.


ABSTRACT: The reconstruction of fractured orbital walls is complex due to the many volumetric parameters involved. An inadequate restitution of these walls may be associated with postsurgical sequelae in the patient. Is vitally important to count with tools that optimize the restitution of the orbit's anatomic shape during its reconstruction, and the use of new technologies has allowed the improvement of the surgical results, both anatomical and functional. The aim of this article is to show two surgical tools that allow to optimize the therapeutic results in patients with orbital fracture, which are stereolithographic models with mirror image technique, and intraoperative computed tomography. Their characteristics, their use in three cases of patients with orbital fractures, and the postoperative results are shown.

ABSTRACT

As infeções de pele e tecidos moles constituem um grupo de patologias de elevada prevalência. A fasceíte necrotizante é a infeção rápida e destrutiva do tecido subcutâneo e fáscia superficial com elevada morbimortalidade. Mais frequente na região perineal é de ocorrência rara na região periorbitária. O relato deste caso ilustra um caso de necrose palpebral bilateral após traumatismo cranioencefálico leve com escoriações. Foi realizado tratamento clínico intensivo e desbridamento cirúrgico da área afetada. Na primeira fase da reconstrução palpebral foi usada matriz de regeneração dérmica. Este substituto cutâneo inicialmente descrito para queimaduras se reveste atualmente de grande importância em cirurgia plástica visando uma melhor e mais rápida cicatrização das feridas. Posteriormente, realizou-se a autoenxertia cutânea tendo-se obtido um bom resultado estético e funcional.


Skin and soft tissue infections are a group of pathologies of high prevalence. Necrotizing fasciitis is a rapid and destructive infection of the subcutaneous tissue and superficial fascia with high morbidity and mortality. It is frequent in the perineal region and of rare occurrence in the periorbital region. This report illustrates a case of bilateral eyelid necrosis after mild head trauma with abrasions. Intensive clinical treatment and surgical debridement of the affected area were performed. In the first phase of eyelid reconstruction, a dermal regeneration matrix was used. This cutaneous substitute initially described for burns is currently of great importance in plastic surgery, aiming to heal wounds better. Subsequently, cutaneous self-grafting was performed, and a good aesthetic and functional result was obtained.

ABSTRACT

Resumen Introducción: El neumomediastino se define como la presencia de aire o gas dentro de los planos fasciales del mediastino. Por lo general, es un fenómeno secundario a perforaciones traumáticas del tracto aerodigestivo. El neumomediastino secundario a una fractura orbitaria es un evento raro. Se asocia a complicaciones potencialmente mortales como el neumotórax, el neumopericardio y la mediastinitis. Objetivo: Describir un caso de neumomediastino secundario a una fractura aislada de piso orbitario y su manejo médico-quirúrgico. Caso clínico: Paciente de sexo femenino de 42 años que sufre traumatismo en regiones facial, cervical y torácica desarrollando secundariamente un enfisema subcutáneo panfacial y un neumomediastino, el cual se resuelve exitosamente. Discusión: El neumomediastino secundario a una fractura aislada de piso orbitario es un evento muy raro. El aire puede descender a lo largo de los espacios fasciales hasta el mediastino. En este sentido, sonarse la nariz es un factor de riesgo para desarrollar esta pa-tología. Conclusión: Ocurrido un trauma maxilofacial puede presentarse enfisemas de espacios profundos de la cabeza, cuello e incluso el mediastino.


Introduction: Pneumomediastinum is defined as the presence of air or gas within the fascial planes of the mediastinum. It is usually a phenomenon secondary to traumatic perforations of the aerodigestive tract. Pneumomediastinum secondary to an orbital fracture is a rare event. And it is related to life-threatening complications such as pneumothorax, pneumopericardium and mediastinitis. Aim: To describe a case of pneumomediastinum secondary to an isolated orbital floor fracture and its medical-surgical management. Clinical case: A 42-year-old female patient who suffers trauma to the facial, cervical and thoracic regions, secondary development of a subcutaneous panfacial emphysema and pneumomediastinum, which resolves successfully. Discussion: Pneumomediastinum following an isolated orbital floor fracture is a very rare event. The air can descend along the fascial spaces to the mediastinum. In this sense, blowing your nose is a risk factor to develop this pathology. Conclusion: After a maxillofacial trauma, emphysema of the deep spaces of the head, neck and even the mediastinum can occur

ABSTRACT

ABSTRACT Septic cavernous sinus thrombosis is a rare but often debilitating and potentially fatal disease. We describe a case of bilateral orbital cellulitis with rapidly progressing cavernous sinus thrombosis and left sigmoidal sinus thrombosis in an immunocompetent 20-year-old military man who had undergone intensive physical training. The patient presented with rapid painful swollen left eye for 2 days. The examination results were gross proptosis with total ophthalmoplegia. He was treated with intravenous antibiotics and corticosteroid. At 1 week, visual acuity improved to 20/20 OU, with a normal intraocular pressure. There was a significant improvement in proptosis. The ocular motility of the right eye was fully restored, with slight residual ophthalmoplegia in the left eye. There was no residual illness or recurrence of illness at 3 months' follow-up.


RESUMO A trombose séptica do seio cavernoso é uma condição rara, mas frequentemente debilitante e potencialmente fatal. Descrevemos um caso de celulite orbital bilateral com progressão rápida para trombose do seio cavernoso e trombose do seio sigmoide esquerdo, em um militar imunocompetente de 20 anos de idade que havia sido submetido a treinamento físico intenso. O paciente apresentou um inchaço rápido e doloroso no olho esquerdo por 2 dias. Os resultados do exame foram proptose macroscópica com oftalmoplegia total. Ele foi tratado com antibióticos intravenosos e costicosteróide. Em 1 semana, a acuidade visual melhorou para 20/20, com pressão intraocular normal. Houve uma melhora significativa na proptose. A motilidade ocular do olho direito foi totalmente restaurada, com leve oftalmoplegia residual no olho esquerdo. Não houve doença residual ou recorrência da doença após três meses de acompanhamento.

ABSTRACT

INTRODUCCIÓN: La miositis orbitaria (MO) es un proceso inflamatorio grave de etiología desconocida que compro mete los músculos extraoculares. La presentación en edad pediátrica es rara y con frecuencia afecta a más de un individuo de una familia, lo que sugiere algún grado de predisposición genética. OBJETIVO: Describir un caso de miositis orbitaria de presentación en edad pediátrica, sus características clínicas, y la utilidad de la imagen por resonancia magnética para la confirmación del diagnóstico. CASO CLÍNICO: Paciente femenina de 13 años que presenta cefalea aguda, dolor periorbitario derecho, exacerbado con los movimientos oculares y visión borrosa a quien se le realizaron estudios para miopatía tiroidea, enfermedades infecciosas, autoinmunidad y cáncer que fueron negativos. En la imagen por resonancia magnética se evidenció miositis del músculo recto medio derecho, sin evi dencia de neuritis óptica. Recibió tratamiento con glucocorticoides sistêmicos intravenosos seguido de esteroides orales con mejoría clínica completa. CONCLUSIONES: La MO tiene etiología desconocida, y puede tener un curso maligno. Dada su presentación clínica inespecífica, el estudio diagnóstico diferencial debe ser amplio, y su estudio debe considerar realizar resonanacia magnética. El inicio temprano del tratamiento con esteroides evita el daño permanente de los músculos extraoculares.


INTRODUCTION: Orbital myositis (OM) is a serious inflammation of extraocular muscles with unknown etiology. Pe diatric presentation is rare and often affects more than one individual in a family, suggesting a genetic predisposition. OBJECTIVE: To describe a pediatric case of orbital myositis, its clinical characteristics, and the usefulness of MRI for confirming the diagnosis. CLINICAL CASE: A 13-year-old female patient presenting with acute headache, right periorbital pain, exacerbated by eye movements, and blurred vision. We ruled out thyrotoxic myopathy, infectious diseases, autoimmunity, and malignancy. An MRI showed right medial rectus muscle myositis and no evidence of optic neuritis. She was treated with intravenous systemic glucocorticoids followed by oral steroids with complete clinical resolution. CONCLUSIONS: OM has unknown etiology and can present a malignant course. Due to its unspecific clinical presentation, a comprehensive differential diagnosis should be made and it should consider performing MRI. Early treatment avoids permanent damage of extraocular muscles.

ABSTRACT

SUMMARY: The pear-shaped bony orbit connects with intracranial cavity via foramina's and fissures. The Meningo-orbital Foramen (MOF) is usually present in greater wing of sphenoid close to lateral edge of Superior orbital fissure. It provides a route for an anastomosis between the orbital branch of the middle meningeal artery (MMA) and recurrent meningeal branch of Ophthalmic Artery (OA) and hence, risk of damage during surgeries can occur. To verify occurrence and location, with morphology of MOF in dry orbits and the impending clinical hazards in surgeries pertaining to the orbit, document and analysis it to determine a standardized guideline. The presence for MOF was studied in 446 dry orbits with its location from the supra orbital margin (SOM), front zygomatic suture (FZS), the lateral tubercle of Whitnall (WT)and the lateral end of superior orbital fissure (SOF) along with its patency, laterality and number of foramina's present. Nylon probes, long divider/pins, compass and Vernier callipers was used to check the patency and various parameters. The study noted the percentage prevalence of MOF as 69 % with communication with middle cranial fossa (MCF) being 76 % of 69 % and the average distance from SOM, FZS, WT and lateral end of SOF being 35.58 mm, 24.9 mm, 26.6 mm and 0.92 mm. On comparison with various population studies, certain similarities and differences with regards to different parameters were noted. Prevalence of MOF was mostly unilateral and showed multiple foramina, that can act as channels for arteries, a variant of MMA or OA, that supply orbital structures or tumour growths. Thus, awareness of this variation is of prime importance to ophthalmologists and neurosurgeons as well as interventional radiologists, in preventing haemorrhagic condition which could further raise the difficulties in operative procedures and surgical outcomes.


RESUMEN: La órbita ósea en forma de pera se conecta con la cavidad intracraneal a través de forámenes y fisuras. El foramen meningoorbitario (MOF) suele estar presente en el ala mayor del esfenoides cerca del margen lateral de la fisura orbitaria superior. Proporciona una ruta para una anastomosis entre la rama orbitaria de la arteria meníngea media (MMA) y la rama meníngea recurrente de la arteria oftálmica (OA) y, por lo tanto, puede ocurrir riesgo de daño durante las cirugías. Para verificar la ocurrencia y ubicación, con la morfología de MOF en órbitas secas y los peligros clínicos inminentes en cirugías de la órbita, documentarlo y analizarlo para determinar una pauta estandarizada. Se estudió la presencia de MOF en 446 órbitas secas desde el margen supraorbitario (MOS), sutura cigomática frontal (FZS), el tubér- culo lateral de Whitnall (WT) y el extremo lateral de la fisura orbitaria superior (SOF) junto con su permeabilidad, lateralidad y número de forámenes presentes. Se utilizaron sondas de nailon, divisores / pasadores largos, brújula y calibradores Vernier para comprobar la permeabilidad. En el estudio se pudo observar que la prevalencia porcentual de MOF era del 69 %, siendo la comunica- ción con la fosa craneal media (MCF) del 76 % del 69 % y la distancia promedio desde SOM, FZS, WT y el extremo lateral de SOF era de 35,58 mm, 24,9 mm, 26,6 mm y 0,92 mm. En comparación con varios estudios de población, se observaron ciertas similitudes y diferencias con respecto a diferentes parámetros. La prevalencia de MOF fue mayoritariamente unilateral y mostró múltiples forámenes, que pueden actuar como canales para las arterias, una variante de MMA u OA, que irrigan estructuras orbitarias o crecimientos tumorales. Por lo tanto, la conciencia de esta variación es de primordial importancia para los oftalmólogos y neurocirujanos, así como para los radiólogos intervencionistas, en la prevención de una enfermedad hemorrágica que podría aumentar aún más las dificultades en los procedimientos y los resultados quirúrgicos.

ABSTRACT

El compromiso orbitario es la complicación más frecuente de la rinosinusitis aguda en pediatría, y el etmoides es el seno más afectado. La recurrencia es infrecuente. Existen solo tres casos publicados en la literatura. Una anomalía anatómica del proceso unciforme o un mucocele podrían ser factores predisponentes, que pueden obstruir el drenaje normal de los senos junto con la presencia de etmoiditis.La tomografía computada y la resonancia magnética orientan el diagnóstico. El tratamiento quirúrgico está indicado ante la falta de respuesta al tratamiento instaurado luego de 48 horas o disminución de la agudeza visual o recurrencias sin patología tumoral de base.Se presenta a un paciente de 4 años de edad que consultó por un cuadro compatible con etmoiditis complicada recurrente. Presentó celulitis preseptal en seis oportunidades y un episodio de absceso subperióstico, desde los 3 meses de edad. Evolucionó favorablemente luego de la operación quirúrgica.


Orbital infection is the most frequent complication of ethmoiditis. Recurrent periorbital cellulitis is a very rare complication of rhinosinusitis with only three reports in the literature describing this pathological process.This complication can be favored by an anatomical abnormality of the uncinate process or mucocele obstructing the normal drainage pathway, in addition to ethmoidal sinusitis.Computed tomography and magnetic resonance guide the diagnosis. The treatment is based on antibiotics, corticosteroids and local decongestants. Surgical treatment is indicated in the absence of response to treatment established after 48 hours or decrease in visual acuity or recurrent orbital complications without underlying tumor pathology. In this report, we present a case of orbital complication of rhinosinusitis in a 4 year-old-child with six episodes of unilateral periorbital cellulitis and one episode of subperiosteal orbital abscess since the age of 3 months. There was a complete resolution with no recurrence after the surgical intervention

ABSTRACT

ABSTRACT Purpose: To evaluate the biocompatibility of three-dimensional (3D) printed orbital spheres for evisceration. Materials: A total of 10 consecutive patients (eight females and two males; mean age, 46.8 ± 14.2 years) underwent evisceration of blind painful eyes. 3D spherical implants produced by a rapid prototype machine were used to restore orbital volume. The implants were produced from a commercially available photocurable resin (Fullcure®). Systemic toxicity was evaluated by comparing serum biochemical measurements (creatine phosphokinase, aspartate aminotransferase, alanine aminotransferase, albumin, creatinine, urea, alkaline phosphatase, and C-reactive protein) before and at 12 months after surgery. Local toxicity was assessed by the evaluation of signs of socket inflammation at the first postoperative month. Changes in implant size were determined by computed tomography scans at 2 and 12 months after surgery. Results: The postoperative evaluations were uneventful. The biochemical evaluation showed no significant changes after surgery. None of the patients presented signs of orbital implant inflammation, infection, exposure, or extrusion. Computed tomography scan evaluations revealed no changes in implant size. Conclusion: To the best of our knowledge, this is the first phase-1 clinical study to certify the biocompatibility of the Fullcure resin for orbital implants in humans. The 3D printing technology permits fast and accurate production of implants for this purpose.


RESUMO Objetivos: Avaliar a biocompatibilidade das esferas produzidas por impressora tridimensional em evisceração. Pacientes e métodos: Evisceração por olho cego doloroso foi realizada em 10 pacientes consecutivos (8 mulheres, idade média: 46.8 ± 14.2 anos). Os implantes esféricos foram produzidos pelo sistema de prototipagem rápida utilizando dados tridimensionais computadorizados. O material utilizado para produção dos implantes foi a resina fotocurável Fullcure®. A avaliação da toxicidade sistêmica do material foi realizada por meio da dosagem de marcadores bioquímicos (creatina fosfoquinase, aspartato aminotransferase, alanina aminotransferase, albumina, creatinina, ureia, fosfatase alcalina, e proteína C-reactiva) antes da cirurgia e aos 12 meses de pós-operatorio. A avaliação da toxicidade local foi realizada por meio do registro qualitativo dos sinais inflamatórios no lado operado durante o primeiro mês de pós-operatório. O tamanho dos implantes foi medido em tomografias computadorizadas (CT) aos 2 e 12 meses de pós-operatório. Resultados: A avaliação bioquímica mostrou que os marcadores estudados não sofreram alterações significativas após a cirurgia. Nenhum paciente apresentou sinais de inflamação atípica, infecção, exposição ou extrusão. A avaliação tomográfica não demonstrou mudanças nos tamanhos dos implantes. Conclusão: O presente trabalho é o primeiro estudo clínico realizado para atestar a biocompatibilidade dos implantes orbitais de resina fotocurável Fullcure. A produção dos implantes pela técnica de impressão tridimensional, utilizando essa resina, permite a disponibilização rápida e acurada do produto final

ABSTRACT

Se presenta el caso clínico de una paciente de 62 años de edad, mestiza, de procedencia rural, quien había sido atendida 3 años atrás en consulta de oftalmología por un tumor de conjuntiva en el ojo izquierdo. Asistió nuevamente a consulta por dicha razón, pero esta vez además existía sangrado profuso y daño grave de las estructuras oculares. Se le realizaron varios exámenes, entre ellos rayos X de órbita, ecografía ocular, tomografías de órbita (con contraste) y cráneo, así como biopsia de la lesión exofítica y estudio inmunohistoquímico. El diagnóstico histológico definitivo fue carcinoma epidermoide de conjuntiva, por lo que se decidió realizar exéresis orbitaria, cirugía plástica reconstructiva y, posteriormente, radioterapia y quimioterapia. La paciente evolucionó favorablemente y fue controlada la diseminación de la neoplasia maligna, lo que además pudo evitarse si la atención médica inicial hubiese sido oportuna.


The case report of a 62 years mestiza patient of rural origin is presented, who had been assisted 3 years ago in the ophthalmology service due to a tumor of conjunctive in the left eye. She went again to the service for this reason, but this time it also existed profuse bleeding and serious damage of the ocular structures. Several exams were carried out, among them orbit X rays, ocular echography, orbit and skull tomographies (with contrast), as well as biopsy of the exofitic lesion and immunohistochemical study. The definitive histologic diagnosis was squamous cell carcinoma of conjunctive, reason why it was decided to carry out orbit exeresis, reconstructive cosmetic surgery and, later on, radiotherapy and chemotherapy. The patient had a favorable clinical course and the dissemination of the malignancies was controlled, what could also be avoided if initial medical care might have been opportune.

ABSTRACT

RESUMEN La orbitopatía tiroidea es una enfermedad autoinmune, en la que una reacción inflamatoria genera aumento de la presión orbitaria con protrusión de su contenido. A menudo es autolimitada y sus síntomas más frecuentes son retracción palpebral, exoftalmo y diplopía. Existen casos severos con compromiso de la agudeza visual por compresión del nervio óptico. El diagnóstico es clínico, pero debe complementarse con una tomografía computarizada. Su tratamiento depende de la gravedad y actividad de la enfermedad, siendo los procedimientos quirúrgicos, como la descompresión orbitaria, de elección en exoftalmo y neuropatía óptica compresiva. El pilar de tratamiento en la orbitopatía tiroidea severa es la cirugía descompresiva. Se han descrito múltiples técnicas, pero con limitaciones. La descompresión endoscópica transnasal, es considerada actualmente el procedimiento de elección, ya que permite una buena visualización de la pared medial, con resultados comparables y menores complicaciones, respecto a métodos tradicionales. Describimos un caso de oftalmopatía tiroidea severa, con exoftalmo, diplopía y disminución de la agudeza visual, en la que se realizó una descompresión endoscópica con muy buenos resultados.


ABSTRACT Thyroid orbitopathy is an autoimmune disease in which an inflammatory reaction generates increased orbital pressure with protrusion of its contents. It is often self-limiting and its most frequent symptoms are eyelid retraction, exophthalmos and diplopia. There are severe cases with compromised visual acuity due to compression of the optic nerve. The diagnosis is clinical, but must be complemented with a computed tomography scan. Its treatment depends on the severity and activity of the disease and the surgicals procedures such as orbital decompression is the best choice in exophthalmos and compressive optic neuropathy. The treatment in severe thyroid orbitopathy is decompressive surgery. Multiple techniques have been described, but with limitations. The transnasal endoscopic decompression is currently considered the gold standard, since it allows a good visualization of the medial wall with comparable results and less complications, compared to traditional methods. We present a case of severe thyroid ophthalmopathy, with exophthalmos, diplopia and decreased visual acuity, in which a transnasal endoscopic decompression was performed with very good outcomes.

ABSTRACT

Introducción: La miositis orbitaria aguda es una afección inflamatoria de la musculatura extrínseca ocular muchas veces de causa desconocida. Forma parte de un grupo de afecciones inflamatorias orbitarias inespecíficas englobadas bajo el término de pseudo tumor orbitario. Afecta principalmente a las mujeres jóvenes. Objetivo: Describir el caso de una adolescente con miositis orbitaria aguda, afección inflamatoria poco frecuente en la edad pediátrica. Presentación del caso: Se trata de una adolescente de 14 años, mestiza, femenina, quien sufrió dengue por tres ocasiones poco tiempo antes de presentarse con dolor ocular del ojo izquierdo, fiebre elevada intermitente, protrusión ocular intermitente, vómitos, cefalea, decaimiento, pérdida de peso y de apetito. El ojo izquierdo presentaba edema del parpado superior y limitación a la abducción, musculatura ocular extrínseca: diplopía horizontal a mirada derecha a izquierda. El ultrasonido ocular informa presencia de imagen quística que no impresiona ser de contenido hemático. El resultado de la tomografía axial computarizada de órbita y cráneo simple fue compatible con diagnóstico de miositis orbitaria. Se indicó tratamiento inmediato con esteroides orales y se remitió al Instituto de Oftalmología Ramon Pando Ferrer para seguimiento. Conclusiones: La miositis orbitaria exige un alto índice de sospecha para un diagnóstico y tratamiento correcto. El dengue pudiera estar implicado en la etiología de la enfermedad(AU)


Introduction: Acute orbitary myositis is an inflammatory condition of the extrinsic ocular musculature, often of unknown cause. It is part of a group of non-specific orbital inflammatory conditions encompassed by the term of orbital pseudotumors. It mainly affects young women. Objective: To describe the case of a teenager with acute orbital myositis which an inflammatory condition not frequent in the pediatric ages. Case presentation: This is a 14-year-old, mixed-race, female patient, who suffered dengue three times before presenting ocular pain in the left eye, intermittent high fever, intermittent ocular protrusion, vomiting, headache, weakness, loss of weight and appetite. The left eye presents edema of the upper eyelid and limitation in abduction. The extrinsic ocular musculature presented: horizontal diplopia in right to left gaze. The ocular ultrasound informs: cystic image that does not impress to be of hematic content. A computerized axial tomography of the orbit and simple skull was performed, and the result was compatible with the diagnosis of orbital myositis. Immediate treatment with oral steroids was indicated and the patient was sent to the Ramon Pando Ferrer Ophthalmology Institute for follow-up. Conclusion: Orbital myositis requires a high index of suspicion for a correct diagnosis and treatment. Dengue seems to be involved in the etiology of the disease(AU)

ABSTRACT

La celulitis orbitaria es la causa más frecuente de inflamación aguda de la órbita y constituye una urgencia oftalmológica relativamente frecuente y potencialmente grave en la población pediátrica. La inflamación puede extenderse a la región postseptal, y afectar el contenido de la órbita. La relación anatómica de la órbita con estructuras vecinas como los senos paranasales, es clave para entender la etiopatogenia de la enfermedad; aparece, en la mayoría de las ocasiones, como complicación de una sinusitis. Se presenta una paciente de cinco años de edad, con diagnóstico de celulitis orbitaria secundaria a una sinusitis. La descripción de las características clínicas de la enfermedad y su manejo en este caso, puede aportar información útil para el mejor abordaje de la entidad. Se concluye que los elementos fundamentales son el diagnóstico temprano y la atención multidisciplinaria.


Orbital cellulitis is the most frequent cause of acute swelling of the orbit and is a relatively frequent ophthalmological emergency and potentially serious in the pediatric population. The inflammation may extend to post septal region, and affect the orbit content. The anatomical relation of the orbit with their neighboring structures as paranasal sinuses is the key to understand the etiopathogenesis of the disease; a case of a five-year-old patient is presented, with a diagnosis of orbital cellulitis secondary to sinusitis. The description of the clinical characteristics of the disease and its management in this case, may offer useful information for a better approach of this entity. It is concluded that the main elements are early diagnosis and multidisciplinary evaluation.

ABSTRACT

Objetivo: describir las características clínico-patológicas de los tumores orbitarios. Métodos: se realizó un estudio descriptivo y retrospectivo de serie de casos en el Instituto de Oncología y Radiobiología desde enero del año 2011 a diciembre de 2017. La muestra se conformó con 241 pacientes sometidos a cirugía de la órbita y fue caracterizada según la edad, el sexo, el origen y la naturaleza de la lesión, el diagnóstico histopatológico y los abordajes quirúrgicos utilizados. Resultados: el 52,7 por ciento de la muestra estudiada fue del sexo masculino; el 36,5 por ciento se encontró en el grupo de 60 a 79 años. El 62,7 por ciento de los casos correspondió a tumores malignos, el 51,9 por ciento a lesiones primarias de la órbita y el 26,6 por ciento a linfoma No Hodgkin. Las lesiones secundarias originadas en los párpados representaron el 58,7 por ciento y el carcinoma epidermoide el 56,5 por ciento. Hubo 11 casos correspondientes a metástasis; las de mama representaron el 72,7 por ciento. El abordaje anterior transpalpebral fue utilizado en el 54,8 por ciento de los casos. Conclusiones: los tumores orbitarios se presentan con mayor frecuencia a partir de los 40 años de edad y con predominio del sexo masculino. Las lesiones malignas son más frecuentes, así como las primarias de la órbita, donde el linfoma No Hodgkin representa el mayor número de casos. Los párpados son la principal estructura de origen de las lesiones secundarias, y el carcinoma epidermoide es la variedad histopatológica predominante. Las metástasis de mama son las que más afectan el espacio orbitario. La vía de abordaje fundamental es la anterior transpalpebral (transeptal), seguido de la exenteración orbitaria(AU)


Objective: describe the clinicopathological characteristics of orbital tumors. Methods: a retrospective descriptive case-series study was conducted at the National Institute of Oncology and Radiobiology from January 2011 to December 2017. A sample of 241 patients undergoing orbital surgery was characterized according to age, sex, origin and type of lesion, histopathological diagnosis and surgical procedures used. Results: 52.7 percent of the study sample was male and 36.5 percent was in the 60-79 age group. 62.7 percent of the cases were malignant tumors, 51.9 percent were primary orbital lesions, and 26.6 percent were non-Hodgkin lymphomas. Secondary lesions originating in the eyelids represented 58.7 percent, and epidermoid carcinomas 56.5 percent. Eleven cases were metastases, 72.7 percent were of the breast type. The anterior transpalpebral approach was used in 54.8 percent of the cases. Conclusions: orbital tumors are more common as of age 40 with a predominance of the male sex. Malignant lesions are more frequent, as well as primary orbital lesions, of which the largest number of cases are non-Hodgkin lymphomas. The eyelids are the main structure of origin of secondary lesions, and epidermoid carcinoma is the prevailing histopathological variety. Breast metastases are the type most commonly affecting the orbital area. The main approach is anterior transpalpebral (transeptal), followed by orbital exenteration(AU)
