ABSTRACT

La reconstrucción posterior a una cirugía oncológica resectiva maxilar es todo un desafío. Debido a esto, existen diversas técnicas quirúrgicas cuyo objetivo apunta a mantener no solo la funcionalidad, sino también la estética facial, especialmente en el área del reborde infraorbitario. El injerto de hueso calvarial es una opción segura y versátil para realizar una reconstrucción primaria en el reborde infraorbitario. Esta técnica está indicada en aquellos pacientes en los cuales la resección cutánea y exenteración orbitaria no son necesarias. Por este motivo, a continuación, analizaremos este tipo de injerto a propósito de un caso clínico en el que se usó asociado a un colgajo pediculado de fascia temporoparietal.


Reconstruction after maxillary resective oncological surgery is a challenge. Because of this, there are many surgical techniques whose objective is to maintain not only function but also facial aesthetics, especially in the infraorbital rim area. The calvarial bone graft is a safe and versatile option to perform a primary infraorbital rim reconstruction. This technique is indicated in those patients in whom skin resection and orbital exenteration are not necessary. For this reason, we will now analyze this type of graft in relation to a case in which it was used associated with a temporo-parietal fascia flap.

ABSTRACT

Objetivos: O carcinoma adenoide cístico é uma lesão rara e agressiva. O presente trabalho visa relatar o caso de uma ressecção de carcinoma adenoide cístico e manutenção do arcabouço ósseo realizado por meio de sonda de Foley insuflada com soro fisiológico. Relato do caso: Um paciente submetido a ressecação de um carcinoma adenoide cístico em maxilla com destruição de soalho de órbita foi relatado. O caso foi realizado no Hospital Josina Machel em Luanda, Angola. A região apresenta uma considerável escassez de materiais de fixação e outros mais, o que impossibilita reconstruções maxilofaciais com a excelência necessária. A realização de enxertos microvascularizados ou implantes customizados torna-se inviável devido aos custos e tecnologia dispendida para tal. Conclusão: A sonda de Foley mostra-se como uma alternativa viável nos casos de reconstrução de terço médio de face com envolvimento de seio maxilar e soalho de órbita em locais de mais difícil acesso...

Objectives: Adenoid cystic carcinoma is a rare and aggressive lesion. The present work aims to report the case of a resection of adenoid cystic carcinoma and maintenance of the bone framework performed using a Foley catheter insufflated with saline solution. Case report: A patient who underwent resection of an adenoid cystic carcinoma in the maxilla with destruction of the orbital floor was reported. The case was carried out at Hospital Josina Machel in Luanda, Angola. The region has a considerable shortage of fixation materials and others, which makes maxillofacial reconstructions with the necessary excellence impossible. The realization of microvascularized grafts or customized implants becomes unfeasible due to the costs and technology used for this purpose. Conclusion: The Foley catheter is a viable alternative in cases of reconstruction of the middle third of the face with involvement of the maxillary sinus and orbital floor in areas that are more difficult to access...

ABSTRACT

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left eye was used as control group. Results: After optic nerve resection and anastomosis, stable ERG amplitude of the right eye was lost after 302 seconds in group 1 and after 296 seconds on group 2. Left eye kept longer stable ERG amplitude curves. Conclusions: The animal model of whole eye transplantation was effective in describing a novel technique to be used in rabbits, with success of the anatomic procedure. Further studies will clarify the best anastomosis methods and maintenance of function of the receptor organ. Translational relevance: this animal model of whole eye transplantation provides a novel perspective for blind patients and the research models, since we describe a novel mammal animal model. This model can be used as basis of a human model of whole eye transplantation in future studies.


RESUMO Objetivo: Descrever uma técnica cirúrgica inovadora para transplante de olho em um modelo animal em coelhos. Métodos: Seis coelhos machos com Dutch Belted foram submetidos à orbitotomia lateral do olho direito, com ampla exposição da anatomia retrobulbar, dissecção do cone muscular, exposição e secção distal do nervo óptico seguida de anastomose por vicryl (Grupo 1) ou cola de fibrina (Grupo 2). O registro da eletrorretinografia foi realizado antes da secção do nervo óptico e a cada 30 segundos após, para monitorar a função da retina. O olho esquerdo foi usado como grupo controle. Resultados: Após a ressecção do nervo óptico, a estabilidade da amplitude da eletrorretinografia foi perdida no olho direito após 302 segundos no Grupo 1 e após 296 segundos no Grupo 2. O olho esquerdo manteve eletrorretinografia estável por períodos mais longos. Conclusão: O modelo animal de transplante total de olho foi eficaz em descrever uma nova técnica cirúrgica para ser utilizada em laboratório com coelhos, com sucesso do procedimento anatômico. Novos estudos esclarecerão os melhores métodos de anastomose e manutenção da função do órgão receptor.

Métodos. Estudo observacional, transversal, descritivo e retrospetivo realizado analisando os registos de pacientes diagnosticados com OAT tratados num centro de cuidados de terceiro nível de janeiro de 2005 a julho de 2016. Os resultados. Um total de 236 órbitas de 118 pacientes foram avaliados, com uma idade média de 47,3 (13,2 anos, 74,6% eram do sexo feminino e 25,4% masculinos. 4,2% dos doentes foram tratados com hipotiroidismo, 94,1% com hipertireoidismo e 1,7% com goiter tóxico difuso. 44,9% dos doentes estudados com restrição de movimento ocular,10,2% com queratopatia de exposição e 51,7% com hipertensão intraocular. 34,7% dos doentes avaliados no serviço necessitaram de descompressão orbital, 16,1% de cirurgia palpebral e 8,5% de correção do hatrabisma. Na gestão conservadora destes doentes, 48,3% exigiam o uso de lubrificantes tópicos dos olhos, enquanto 52,5% dos pacientes necessitavam do uso de hipotensivos oculares em número variável. As conclusões. A OAT foi associada principalmente ao hipertiroidismo, sendo mais comum em pacientes do sexo feminino entre os 40 e os 59 anos; mais de 50% dos pacientes necessitaram do uso de hipotensivos oculares. Da mesma forma, a gestão cirúrgica foi realizada em mais de 50% dos pacientes, sendo a descompressão orbital a intervenção mais frequente.


ABSTRACT Objective. To know the demographic and clinical characteristics of Thyroid Associated Orbitopathy (TAO), as well as the requirement rate of orbital surgery in patients of the Orbit Service in the National Medical Center of the West, IMSS. Methods. Observational, cross-cutting, descriptive and retrospective study carried out analyzing the records of patients diagnosed with TAO and treated at a third-level care center from January 2005 to July 2016. Results. A total of 236 orbits of 118 patients were valued, with an average age of 47.3 ± 13.2 years, 74.6% were female and 25.4% male. 4.2% of patients were treated with hypothyroidism, 94.1% with hyperthyroidism and 1.7% with diffuse toxic goiter. 44.9% of patients studied had eye movement restriction,10.2% exposure keratopathy and 51.7% intraocular hypertension. 34.7% of patients valued in the service required orbital decompression, 16.1% palpebral surgery and 8.5% strabism correction. In the conservative management of these patients 48.3% required the use of topical eye lubricants, while 52.5% required the use of eye hypotensives in variable numbers. Conclusions. TAO was mainly associated with hyperthyroidism, being more common in female patients between the age of 40 and 59; more than 50% of patients required the use of eye hypotensives. Likewise, surgical management was performed in more than 50% of patients, with orbital decompression being the most frequent intervention.

ABSTRACT

OBJECTIVES: To compare the surgical outcomes of inferomedial wall orbital decompression (IM-OD) and balanced medial plus lateral wall orbital decompression (ML-OD) in patients with inactive Graves' orbitopathy (GO) with regard to exophthalmos reduction and ocular motility abnormalities. METHODS: Forty-two patients with inactive GO eligible for OD were randomly assigned to either the IM-OD or ML-OD groups. Pre and postoperative evaluations included Hertel exophthalmometry, sensory, and motor extraocular motility assessment, standardized photographs in the nine gaze positions, and computed tomography (CT) of the orbits. ClinicalTrials.gov: NCT03278964. RESULTS: Exophthalmometry reduction was statistically significant in both groups (p<0.001), but was greater in the ML-OD group (p=0.010). New-onset esotropia occurred in 11.1% and 23.5% of patients who underwent IM-OD and ML-OD, respectively, with no statistically significant difference in the frequency of pre and postoperative strabismus in either group. The mean increase in preoperative esotropia was 24±6.9 and 12±8.8 prism diopters in patients who underwent IM-OD and ML-OD, respectively. In the IM-OD group, abduction and elevation worsened at the first (p<0.05) and third (p<0.05) postoperative visits but were restored at 6 months. The versions did not change postoperatively with ML-OD. The preoperative CT-measured medial rectus muscle area predicted new-onset strabismus (p=0.023). Significant postoperative medial rectus muscle enlargement occurred in both groups (p<0.001). Restriction in elevation and abduction was significantly associated with enlarged inferior (p=0.007) and medial rectus muscle areas (p=0.002). CONCLUSIONS: IM-OD is as safe as ML-OD with regard to new-onset strabismus, and represents a good alternative for patients who do not require significant exophthalmos reduction. ML-OD offers greater exophthalmos reduction and smoother postoperative recovery. Patients with preoperative enlarged medial rectus muscle on CT are at risk for new-onset esotropia, and preoperative esotropia is likely to increase after OD.

ABSTRACT

ABSTRACT We present a patient who underwent evisceration surgery after spontaneous rupture of the ocular globe due to long-data uncontrolled glaucoma, with posterior placement of an orbital implant made of a bone cement compound based on polymethylmethacrylate as alternative materials were not available. Such a compound is characterized by excellent biocompatibility and low cost, which makes it an interesting alternative for treatment. The anophthalmic socket was successfully filled, providing proper esthetic results and favorable conditions for the posterior scleral prosthesis implantation. No complications were observed during 10 months of follow-up. We believe that, in the absence of alternative materials, low-cost materials may be used in emergency settings to repair anophthalmic cavities and provide satisfactory functional and esthetic outcomes.


RESUMO Apresentamos um paciente que foi submetido à cirurgia de evisceração após ruptura espontânea do globo ocular devido a glaucoma não controlado de longa data, com posterior colocação de implante orbital feito de cimento ósseo, composto à base de polimetilmetacrilato, diante da indisponibilidade de materiais alternativos. Tal composto se caracteriza pela excelente biocompatibilidade e baixo custo, o que o torna uma alternativa interessante para o tratamento. A cavidade anoftálmica foi preenchida com sucesso, fornecendo resultados estéticos adequados e condições favoráveis para o implante posterior de prótese escleral. Nenhuma complicação foi observada durante os 10 meses de seguimento. Acredi­tamos que, na ausência de materiais alternativos, materiais de baixo custo podem ser usados em situações emergenciais para preencher cavidades anoftálmicas e prover resultados funcionais e estéticos satisfatórios.

ABSTRACT

ABSTRACT Purposes: To identify problems caused by prosthesis-socket volume imbalances in anophthalmic sockets; and to evaluate rehabilitation with dermofat graft as a solution. Methods: We retrospectively reviewed medical records of patients operated in our clinic (between May 2011 and June 2016) with dermofat grafts to treat anophthalmic socket-related problems. During the preoperative examinations, ophthalmologists recorded the presence of eyelid problems due to the socket volume deficit, upper and lower fornix deficiency, deepening in the upper eyelid sulcus, epiphora and secretion, lower eyelid laxity, ptosis, entropion, and ectropion. Following the surgical repair, new prosthesis suitable for the resulting socket area were implemented for all the patients. The mean follow-up period was 27.42±16 months (ranging from 10-62 months). On the last control examinations, ophthalmologists recorded solved and unsolved socket problems that were present preoperatively. Results: We included 16 men and 5 women in this study. The mean age was 38.3 ± 18.4 years (range, 5-75 years). The mean duration of preoperative prosthesis use was 9.4 ± 6.8 years (range, 1-30 years). Preoperatively, 7 patients had only orbital volume deficits, and 14 had socket volume displacements in addition to the volume deficits. After the dermofat graft implantations, the remaining deficits were corrected during another surgical session: 6 patients underwent ptosis corrections, 5 lateral canthal suspensions, 5 lower fornix with mucosal graft formations, and 2 upper fornix formations with mucosal grafts. All patients were able to use prosthesis postoperatively. Conclusion: The use of dermofat grafts to correct anophthalmic socket problems caused by orbital volume deficits or volume displacements is an effective, reliable, and reproducible surgical method.


RESUMO Objetivos: Identificar os problemas causados pelo desequilíbrio do volume da cavidade da prótese em cavidades anoftálmicas, e avaliar a reabilitação com enxerto de dermofato como solução. Métodos: Revisamos retrospectivamente os prontuários de pacientes operados em nossa clínica (entre maio de 2011 e junho de 2016) com enxertos de dermofato para tratar problemas relacionados a cavidades anoftálmicas. Durante os exames pré-operatórios, os oftalmologistas registraram a presença de problemas palpebrais devido ao déficit de volume, deficiência de fórnice superior e inferior, aprofundamento no sulco palpebral superior, a epífora e secreção, flacidez palpebral inferior, ptose, entrópio e ectrópio. Após a cirurgia, novas próteses adequadas para a área de encaixe foram implementadas em todos os pacientes. O tempo médio de acompanhamento foi de 27,42 ± 16 meses (variando de 10 a 62 meses). Nos últimos exames de controle, os oftalmologistas registraram problemas corrigidos e não corrigidos da cavidade que estavam presentes no pré-operatório. Resultados: Foram incluídos 16 homens e 5 mulheres neste estudo. A média de idade foi de 38,3 ± 18,4 anos (variação de 5-75 anos). A duração média do uso de prótese pré-operatória foi de 9,4 ± 6,8 anos (variação de 1 a 30 anos). No pré-operatório, 7 pacientes apresentavam apenas déficit orbitais e 14 tinham desvios de volume, além dos déficits de volume. Após os implantes de enxerto de dermoadipação, os déficits remanescentes foram corrigidos durante outra sessão cirúrgica: 6 pacientes foram submetidos a correção de ptose, 5 suspensões de cantal lateral, 5 fórnix inferior com enxerto de mucosa e 2 formações de fórnice superior com enxerto de mucosa. Todos os pacientes foram capazes de usar prótese no pós-operatório. Conclusão: A utilização de enxertos de dermofato para corrigir problemas de anoftalmia causados por déficits de volume orbital ou deslocamento de volume é um método cirúrgico eficaz, confiável e reprodutível.

ABSTRACT

A neurofibromatose tipo 1 é uma doença autossômica dominante rara, com manifestações clínicas diversas. Sua apresentação mais marcante é a presença de neurofibromas (tumores da bainha neural) cutâneos ou internos, que também podem ocorrer de forma esporádica, associados a outras manifestações sistêmicas, como manchas café com leite e lesões oculares. Por serem tumores da bainha de mielina, os neurofibromas podem acometer diversos nervos periféricos, incluindo nervos da face. Apresentamos o caso de um paciente de 1 ano, portador de neurofibromatose tipo 1, com neurofibroma em nervo infraorbital direito, com o acesso proposto para tratamento cirúrgico que fornecesse ampla visualização e acesso a lesão, sem comprometimento estético importante, permitindo preservação de partes moles e adequado crescimento facial.


Neurofibromatosis type 1 (NF1) is a rare autosomal dominant disease with multiple clinical manifestations. Its most significant presentation is cutaneous or subcutaneous neurofibromas (myelin sheath tumors), which may be associated with other systemic manifestations such as caféau- lait spots and eye involvement. Neurofibromas can affect several peripheral nerves, including the facial nerves. This report presents a case of a 1-year-old patient with NF1 with right infraorbital nerve neurofibroma in which the proposed access for surgical treatment allowed adequate visualization of the tumor with good aesthetic results, preservation of the soft tissues, and normal facial growth.

ABSTRACT

Introdução: Os retalhos interpolados são opções cirúrgicas eficazes para reconstruções de defeitos cutâneos em várias áreas do corpo, inclusive na face. O retalho proposto dispensa cuidados pós-operatórios com o pedículo exposto e pode ser realizado em tempo único. O objetivo é avaliar a utilidade do retalho interpolado de sulco nasogeniano (RISN) em ilha, na reconstrução de segmentos nasais e do canto interno da órbita, bem como discutir refinamentos em seu design e execução. Métodos: Estudo retrospectivo de prontuários de pacientes com defeitos nasais ou de canto interno da órbita, e que foram reparados com retalho interpolado do sulco nasogeniano. Todos os retalhos foram confeccionados de maneira randômica, realizando-se túnel subcutâneo para evitar pedículo exposto e cicatriz que comunicasse a área doadora e o defeito. Resultados: cinco pacientes foram incluídos no estudo, com idade entre 30 e 92 anos. Em todos os casos foi realizada biópsia de congelação intraoperatória que revelou margens livres de doença, orientando a extensão da ressecção. O CBC foi encontrado em 4 pacientes e o CEC em um paciente. Não houve complicações como sangramento pós-operatório ou necrose. Bons resultados funcionais e estéticos foram alcançados em todos os pacientes. Discussão: Vale ressaltar a versatilidade do retalho nasogeniano interpolado, sendo capaz de auxiliar na reconstrução de defeitos extensos não apenas de asa, ponta e columela nasais, mas também de dorso e canto medial do olho. Destaca-se também o aspecto estético mais favorável do pedículo do retalho interpolado em ilha comparado ao de transposição. Conclusão: O RISN interpolado em único estágio é uma opção confiável na reconstrução de segmentos faciais. Apresenta boa vascularização, possibilidade se ser realizado em único tempo e pode ser utilizado para cobertura nos locais onde há poucas opções reconstrutivas disponíveis.


Introduction: Interpolation flaps are effective surgical options for reconstructing skin defects in various areas of the body, including the face. The proposed flap does not require postoperative care with the pedicle exposed and can be performed in a single surgery. The objective is to evaluate the usefulness of the nasolabial interpolation island flap (NIF) for reconstructing nasal segments and the inner corner of the eye, as well as discuss improvements in its design and performance. Methods: In this retrospective study, medical records of patients with nasal defects that were repaired with a nasolabial interpolation flap were reviewed. All flaps were created with a subcutaneous tunnel to avoid pedicle exposure and prevent scar connection with the donor area and the defect. Results: Five patients aged 30­92 years were included. In all cases, intraoperative frozen biopsy revealed disease-free margins, indicating the extent of the resection. Basal cell carcinoma was found in four patients and squamous cell carcinoma in one. There were no complications such as postoperative bleeding or necrosis. Good functional and aesthetic results were achieved. Discussion: The NIF can help in the reconstruction of extensive defects of the nasal ala, tip, columella, and medial dorsum as well as the corner of the eye. We also highlight the more favorable aesthetic aspect of the pedicle in the interpolation island versus transposition flap. Conclusion: The single-stage NIF flap is a reliable option for reconstructing facial segments as it has good vascularization, can be performed in a single surgery, and can be used to cover places where few other reconstructive options are available.

ABSTRACT

ABSTRACT Lipoma is a usually painless benign adipose tumor. Nevertheless, it can cause compression of adjacent structures, depending on its location. Mucoceles are benign cystic lesions in the frontal-ethmoidal region, caused by chronic obstruction of the paranasal sinus and consequent inflammatory processes. The increase of mucocele diameter caused by inflammation often results in bony degradation and reabsorption, increasing pressure on adjacent structures, including the orbit and the base of the skull, leading to possibly serious consequences. Here we report a case of lipoma mimicking a frontal mucocele, managed surgically at the Ophthalmological Hospital of Anapolis.


RESUMO O lipoma é um tumor do tecido adiposo de caráter benigno, usualmente indolor, porém que pode gerar compressão de estruturas adjacentes, dependendo da sua localização. A mucocele consiste em uma lesão cística de caráter benigno, na região fronto-etmoidal, devido à obstrução crônica dos óstios dos seios paranasais e consequente processo inflamatório. O aumento do diâmetro da mucocele por inflamação muitas vezes causa degradação e reabsorção ósseas, o que pode elevar a pressão em estruturas adjacentes como órbita e base de crânio, causando intercorrências possivelmente graves. Neste estudo relatamos um caso de lipoma simulando mucocele frontal, com propedêutica cirúrgica.

ABSTRACT

INTRODUCCIÓN: La cirugía oculoplástica estudia y trata los trastornos de párpados, órbita y vías lagrimales. Entre las patologías más importantes por frecuencia e impacto tenemos: ptosis palpebral, blefarochalasis, ectropión y entropión. OBJETIVO: Analizar la experiencia del Hospital El Pino en cuanto al manejo de patología oculoplástica en manos de un cirujano plástico. MATERIALES Y MÉTODO: Estudio descriptivo y retrospectivo. Se revisaron fichas de pacientes operados con diagnóstico de blefarochalasis, ptosis palpebral, ectropión y entropión entre los años 2010 y 2017. Se analizaron datos como edad, sexo, comorbilidades, causa del defecto, cirugía oculoplástica, tipo de anestesia, complicación posoperatoria, tiempo de seguimiento y resultados. RESULTADOS: Entre los años 2010 y 2017 se operaron 79 pacientes con patología oculoplástica, 17 por ptosis palpebral, 42 por blefarochalasis, 14 por ectropión y 6 por entropión, siendo la principal causa senil (93,7%). Las cirugías realizadas fueron: pexia del elevador para Ptosis palpebral, blefaroplastía para blefarochalasis y para ectropión-entropión tarsal strip. La principal técnica anestésica utilizada fue anestesia local + sedación (54,4%). Entre el total de complicaciones posoperatorias tenemos: lagoftalmo (2 casos), ectropión residual (3 casos), conjuntivitis (3 casos), dehiscencia de herida (2 casos) y hematoma palpebral (1 caso). Se reintervinieron 6 pacientes por complicaciones. Los resultados obtenidos según la evaluación subjetiva del cirujano plástico y pacientes fueron regular (5 casos), bueno (20 casos) y muy bueno (54 casos). CONCLUSIÓN: El manejo de la patología oculoplástica requiere en su mayoría de cirugías ambulatorias con buenos resultados y poca morbilidad, lo cual es factible de realizar en un hospital público. Creemos necesario el uso de algún instrumento objetivo para evaluar de mejor manera los defectos palpebrales y su corrección.


INTRODUCTION: The oculoplastic surgery studies and treats disorders of the eyelids, orbit and lacrimal ways. Among the most important pathologies by frequency and impact are: palpebral ptosis, blepharochalasis, ectropion and entropion. AIM: Analyze the experience of El Pino Hospital regarding the management of oculoplastic pathology in the hands of a plastic surgeon. MATERIALS AND METHOD: Descriptive and retrospective study. We reviewed files of patients operated with diagnosis of blepharochalasis, palpebral ptosis, ectropion and entropion between the years 2010 and 2017. Data were analyzed as age, sex, comorbidities, cause of the defect, oculoplastic surgery, type of anesthesia, postoperative complication, follow-up time and results. RESULTS: Between the years 2010 and 2017, 79 patients with oculoplastic pathology operated, 17 for palpebral ptosis, 42 for blefarochalasis, 14 for ectropion and 6 for entropion, being the main senile cause (93,7%). The surgeries performed were: elevator pexis for palpebral ptosis, blepharoplasty for blefarochalasis and for ectropion-entropion tarsal strip. The main anesthetic technique used was local anesthesia + sedation (54,4%). Among the total postoperative complications, we have: lagophthalmos (2 cases), residual ectropion (3 cases), conjunctivitis (3 cases), wound dehiscence (2 cases) and palpebral hematoma (1 case). Six patients were reoperated due to complications. The results obtained according to the subjective evaluation of the plastic surgeon were regular (5 cases), good (20 cases) and very good (54 cases). CONCLUSION: Management of oculoplastic pathology requires mostly ambulatory surgeries with good results and low morbidity, which is feasible to perform in a public hospital. We believe it is necessary to use some objective instrument to better evaluate the palpebral defects and their correction.

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

ABSTRACT Purpose: To evaluate the outcomes of dermis-fat graft procedure for orbital volume replacement in anophthalmic socket. Methods: A retrospective chart review was performed studying all dermis-fat graft surgeries done at King Khlaed Eye Specialist Hospital in the last 10-year period. Sixty-two anophthalmic socket carriers underwent dermis-fat graft during the study period. Data were collected on characteristics of the patients, postoperative complications, cosmesis, and functional results such as the ability to hold an external prosthesis. Results: Mean age of the patients included in the study was 34.2 ± 9.7 years. There were 38.7% of patients with grade 3 anophthalmic socket, 64.5% of patients had an acquired anophthalmic socket, and dermis-fat graft was performed as a secondary procedure in 61.3% of patients. Postoperative complications included lagophthalmos (22.6%), graft necrosis (17.7%), pyogenic granuloma (12.9%), decreased graft size (12.9%), malpositioned lids (3.2%), and volume deficiency (3.2%). The prosthesis was held in place in 49 patients (79%) preoperatively and in 55 patients (88.7%) postoperatively. Conclusion: Dermis-fat graft is an excellent option for congenital or acquired as well as primary or secondary anophthalmic sockets, with or without contraction. The outcomes are favorable, and complications are rare.


RESUMO Objetivo: Avaliar os resultados obtidos com o uso do enxerto dermo-adiposo para reposição de volume em cavidade anoftálmica. Métodos: Estudo retrospectivo baseado em revisão de prontuários incluindo todas as cirurgias de enxerto dermo-adiposo realizadas nos últimos 10 anos no King Khaled Eye Specialist Hospital, Saudi Arabia. O enxerto dermo-adiposo foi realizado em 62 pacientes no periodo do estudo. Os dados analisados incluíram características dos pacientes, as complicações pós- operatórias e os resultados cosméticos e funcionais, tais como a habilidade de usar prótese externa. Resultados: A média de idade dos participantes foi de 34,2 ± 9,7 anos. Segundo a classificação das cavidades, 38,7% possuíam cavidade grau 3; 64,5% possuíam cavidade anoftálmica adquirida e o enxerto dermo-adiposo foi realizado como procedimento secundário em 61,3% dos pacientes. Após o procedimento 22,6% dos pacientes permaneceram com lagoftalmo, 17,7% tiveram necrose do enxerto, 12,9% desenvolveram granuloma piogênico, 12,9% tiveram redução do tamanho do enxerto, 3,2% permaneceram com as alterações no posicionamento palpebral e 3,2% continuaram com déficit de volume na órbita. Quarenta e nove pacientes (79%) eram capazes de usar prótese externa antes da cirurgia e depois do enxerto dermo-adiposo 55 (88,7%) puderam utilizar prótese externa. Conclusão: O enxerto dermo-adiposo é uma ótima opção para tratamento de cavidades anoftálmicas congênitas ou adquiridas, assim como realizado como procedimento primário ou secundário, em cavidades com ou sem contração tecidual. Os resultados são encorajadores e as complicações são pouco frequentes.

ABSTRACT

Resumo Paciente do sexo feminino, 29 anos, ex-tabagista, diagnosticada em setembro de 2012 com doença de Graves e apresentação rápida de exoftalmia bilateral. Na avaliação oftalmológica, apresentava motilidade preservada, proptose e bolsa de gordura superior em AO com retração de PPSS e PPII e exoftalmetria em OD de 26 mm,e em OE de 24 mm. Em maio de 2014,fez o mapeamento da retina que evidenciou cicatrizes de coriorretinite em ambos os olhos e campimetria computadorizada, apresentando degrau nasal em OD, contração superior, depressão centro-inferior. Em junho de 2016, realizou cirurgia de descompressão orbitária de paredes medial e inferior bilateral por via endoscópica com uso de endoscópio nasal Karl Storz, em 30 graus de óptica. A abordagem cirúrgica da oftalmopatia de Graves deve ser empregada na fase cicatricial exceto nos casos com risco de perda da visão. Antes realizada por acesso externo, atualmente a descompressão orbitária pode ser realizada via endoscópica, com mínima invasividade e permite a remoção da parede inferior e medial sem necessidade de incisões externas. É um procedimento seguro para o tratamento da orbitopatia distireoidiana associada a menor morbidade, no qual se evita lesões ao ducto nasolacrimal, nasofrontal ou ao infraorbital e se possibilita redução da proptose entre 3 a 4 mm. Os benefícios da descompressão estão relacionados com a melhora da acuidade visual, além do resultado estético. A continuidade do tratamento cirúrgico será realizada por meio de correção de retração palpebral seguida de blefaroplastia.


Abstract Female, 29, former smoker, diagnosed in September 2012 with Graves' disease and rapid presentation of bilateral exophthalmos. In the ophthalmologic evaluation, it presented preserved motility, proptosis and upper fat sac in OA with retraction of PPSS and PPII and exophthalmetry in OD of 26 mm, and in OE of 24 mm. In May 2014, he performed the mapping of the retina that showed scars of chorioretinitis in both eyes and computerized campimetry, presenting a nasal step in OD, superior contraction, central-inferior depression. In June 2016, he underwent orbital decompression surgery of the medial and inferior bilateral walls by endoscopic approach using the Karl Storz nasal endoscope at 30 degrees of optics. The surgical approach of Graves' ophthalmopathy should be used in the cicatricial phase except in cases with risk of loss of vision. Before performed by external access, orbital decompression can now be performed endoscopically, with minimal invasiveness and allows the removal of the inferior wall and Without external incisions. It is a safe procedure for the treatment of dysthyroidal orbitopathy, associated with lower morbidity, in which lesions are avoided in the nasolacrimal, nasofrontal, or infraorbital ducts and it is possible to reduce proptosis between 3 and 4 mm. The benefits of decompression are related to Improvement of visual acuity, besides the aesthetic result. The continuation of the surgical treatment will be performed by correction of palpebral retraction followed by blepharoplasty.

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

RESUMO Objetivo: Avaliar a biocompatibilidade da Nanoskin para reposição de volume em cavidades enucleadas ou evisceradas de coelhos. Métodos: Estudo experimental, utilizando implantes de Nanoskin (Innovatecs®, São Carlos, Brasil), celulose bacteriana produzida pela bactéria Acetobacter xylinum tendo como substrato o chá-verde. Implantes de 10mm de diâmetro/5mm de espessura foram colocados em cavidades enucleadas (G1) ou evisceradas (G2) de 21 coelhos, avaliados clinicamente todos os dias, sacrificados aos 7, 30 e 90 dias após a cirurgia. O material foi removido e preparado para exame de microscopia óptica. Resultados: Sinais flogísticos discretos no pósoperatório imediato, não tendo sido evidenciados sinais infecciosos ou extrusão de nenhum implante. Houve aparente redução do volume ao longo do período experimental. Histologicamente ambos os grupos foram muito semelhantes, apresentando aos 7 dias células inflamatórias (predominantemente monócitos e neutrófilos), rede de fibrina e hemácias. A Nanoskin apresentava-se como pequenas esferas, de cor rósea, com pequenos espaços entre elas, permeados por escassas células inflamatórias. As células inflamatórias se modificaram ao longo de período experimental, sendo possível observar aos 30 dias células gigantes multinucleadas e fibroblastos maduros permeando o implante. Aos 90 dias, a estrutura do implante apresentava-se desorganizada, amorfa, com restos necróticos e com áreas ovoides, revestidas por fina membrana rósea, que pareciam se agrupar, vazias ou preenchidas por material acelular, róseo ou acinzentado. Conclusão: A Nanoskin provocou reação inflamatória que levou à reabsorção e redução do volume do implante. Novas formulações devem ser estudadas a fim de ter um produto que seja permanente para reparo da cavidade anoftálmica.


ABSTRACT Objective: The aim of this study was to evaluate the biocompatibility of Nanoskin for replacing volume in enucleated or eviscerated anophthalmic sockets of rabbits. Methods: An experimental study was carried out using enucleated or eviscerated rabbits, which received Nanoskin implants (Innovatecs®, São Carlos, Brazil), a cellulose produced by a bacteria (Acetobacter xylinum) using green tea as substrate. Implants of 10mm diameter/5mm of thickness were used placed in enucleated (G1) or eviscerated (G2) anophthalmic sockets of 21 rabbits.They were clinically examined daily, sacrificed at 7, 30 and 90 days after surgery and the material was removed and prepared for histological examination. Results: There were discrete signs of inflammation in the immediate postoperative period, with no evidence of infection or extrusion in any animal. However apparent reduction of volume during the trial period occurred. Histologically both groups were similar, with inflammatory cells (mainly monocytes and neutrophils), fibrin and hemaceas at 7 days postoperatively.The Nanoskin was presented as small pink spheres, with small gaps between them and permeated by few inflammatory cells. These cells have changed over the study, at 30 days multinucleated giant cells and mature fibroblasts that permeate the implant were observed. At 90 days, the structure of the implant was disorganized, amorphous, with necrotic debris and ovoid areas covered with thin pink membrane that seemed to cluster, empty or filled with no cellular pink or gray material. Conclusion: Nanoskin caused an inflammatory reaction leading to reabsorption and reduction of implant volume. New formulations should be studied in order to have a permanent product to repair the anophthalmic socket.

ABSTRACT

INTRODUÇÃO: Fraturas zigomático-orbitárias são as mais comuns do terço médio da face. As principais causas de fraturas são os acidentes de trânsito, principalmente por motocicletas, e a violência interpessoal. Os princípios básicos para o tratamento das fraturas faciais são a redução e a fixação do foco fraturário. É fundamental que o acesso cirúrgico seja o mais direto e amplo possível. Pode ser utilizada abordagem subciliar e transconjuntival com cantotomia lateral. O objetivo deste estudo é avaliar e comparar as complicações, vantagens e desvantagens da abordagem transconjuntival com cantotomia lateral e o acesso subciliar convencional. MÉTODOS: Foram selecionados 15 pacientes nos quais as fraturas foram abordadas por meio de incisão subciliar e 15 pacientes nos quais as fraturas foram abordadas por incisão transconjuntival com cantotomia lateral e avaliadas a incidência de complicações com os dois métodos. Os dados foram analisados estatisticamente com o software SPSS 20.0. RESULTADOS: Foram operados 30 pacientes, metade com acesso subciliar e metade com acesso transconjuntival. Os traumas ocorreram mais frequentemente aos finais de semana. As complicações mais frequentes foram cicatriz aparente (26%), esclera aparente (23,3%) e ectrópio (20%). Ectrópio foi mais comum no grupo acima de 60 anos. CONCLUSÃO: Ambas as técnicas foram eficazes para correção das fraturas do complexo zigomático-orbitário. A técnica transconjuntival proporciona cicatrizes mais estéticas e menos estigmatizantes, constituindo hoje a primeira escolha do autor. A incidência global de complicações foi semelhante entre as duas técnicas. Ectrópio foi menos frequente com acesso transconjuntival.


INTRODUCTION: Orbitozygomatic fractures most commonly occur in the midface. The main causes of fractures are traffic accidents, mainly by motorcycles, and interpersonal violence. The basic principles for the treatment of facial fractures are the reduction and fixation of the fracture site. It is fundamental that the surgical access be the most direct and broad as possible. Either the subciliary approach or transconjunctival access with lateral canthotomy can be used. The objective of this study was to evaluate and compare the complications, advantages, and disadvantages of the transconjunctival approach with lateral canthotomy and conventional subciliary access. METHODS: We selected 15 patients in whom fractures were addressed through a subciliary incision and 15 patients in whom the fractures were addressed by using a transconjunctival incision with lateral canthotomy, and evaluated the incidence of complications with the two methods. The data were statistically analyzed by using the SPSS 20.0 software. RESULTS: Thirty patients were operated with the subciliary access in 15 patients and the transconjunctival access in the other 15. Trauma occurred more frequently on weekends. The most frequent complications were apparent scar (26%), apparent sclera (23.3%), and ectropion (20%). Ectropion was more common in the > 60-year age group. CONCLUSION: Both techniques were effective for the correction of fractures of the orbitozygomatic complex. The transconjunctival technique provides more esthetic and less stigmatizing scars. Hence, it is currently the author's first choice of treatment. The global incidence of complications was similar between the two techniques. Ectropion was less frequent with the transconjunctival access.

ABSTRACT

PURPOSE: To evaluate the efficacy and safety of customized orbital decompression surgery combined with eyelid surgery or strabismus surgery for mild to moderate thyroid-associated ophthalmopathy (TAO). METHODS: Twenty-seven consecutive subjects who were treated surgically for proptosis with disfigurement or diplopia after medical therapy from September 2009 to July 2012 were included in the analysis. Customized orbital decompression surgery with correction of eyelid retraction and extraocular movement disorders was simultaneously performed. The patients had a minimum preoperative period of 3 months of stable range of ocular motility and eyelid position. All patients had inactive TAO and were euthyroid at the time of operation. Preoperative and postoperative examinations, including vision, margin reflex distance, Hertel exophthalmometry, ocular motility, visual fields, Goldmann perimetry, and subject assessment of the procedure, were performed in all patients. Data were analyzed using paired t-test (PASW Statistics ver. 18.0). RESULTS: Forty-nine decompressions were performed on 27 subjects (16 females, 11 males; mean age, 36.6 +/- 11.6 years). Twenty-two patients underwent bilateral operations; five required only unilateral orbital decompression. An average proptosis of 15.6 +/- 2.2 mm (p = 0.00) was achieved, with a mean preoperative Hertel measurement of 17.6 +/- 2.2 mm. Ocular motility was corrected through recession of the extraocular muscle in three cases, and no new-onset diplopia or aggravated diplopia was noted. The binocular single vision field increased in all patients. Eyelid retraction correction surgery was simultaneously performed in the same surgical session in 10 of 49 cases, and strabismus and eyelid retraction surgery were performed in the same surgical session in two cases. Margin reflex distance decreased from a preoperative average of 4.3 +/- 0.8 to 3.8 +/- 0.5 mm postoperatively. CONCLUSIONS: The customized orbital decompression procedure decreased proptosis and improved diplopia, in a range comparable to those achieved through more stepwise techniques, and had favorable cosmetic results when combined with eyelid surgery or strabismus surgery for mild to moderate TAO.

ABSTRACT

ABSTRACTThis literature review considers the treatment of an anophthalmic socket and the controversial aspects of the implants used to restore the lost volume after enucleation or evisceration, including the different materials employed and the main problems encountered during anophthalmic socket reconstruction. Since the 1980s, when integrated implants were proposed, there has been much controversy about what is the best implant for restoring the lost volume in an anophthalmic socket: integrated or non-integrated implants. Thus, we present this literature review to provide guidance to doctors and consumers.


RESUMOEsta revisão da literatura abrange o tratamento da cavidade anoftálmica, assim como os controversos aspectos relacionados com os implantes de cavidade utilizados para recompor o volume perdido após enucleações ou eviscerações, tais como os diferentes materiais utilizados e os principais problemas enfrentados na reconstrução da cavidade anoftálmica. Depois dos anos 80 do século passado, quando foram introduzidos os implantes integrados, há muitas controvérsias sobre qual seria o melhor implante para recompor o volume perdido na cavidade anoftálmica: implante integrado ou não integrado? Desta forma, apresentamos esta revisão da literatura, que procura melhor orientar médicos e consumidores.

ABSTRACT

Trigeminal neuralgia or tic douloureux is a commonly diagnosed facial pain syndrome with a female predominance and with peak occurrence in the age group of above 50 years. Treatment options range from conservative pharmacologic therapy to invasive surgical procedures. The mode of treatment is based on patient’s systemic health, compliance and severity of the disease. Peripheral neurectomy is the safest and simplest method that can be accomplished under local anesthesia with minimum risks and excellent pain relief to the patient. However, there are incidences where this mode of treatment also fails to manage the disease, and further surgical options must be considered. In this case report, we present a case of a 50-year-old female patient who has undergone peripheral neurectomy of infraorbital nerve.
