ABSTRACT

El colgajo peroneo posterior es un colgajo fasciocutáneo, que está basado en 4 posibles fuentes como son perforantes fasciocutáneas de la arteria peronea, perforantes fasciocutáneas de la arteria tibial posterior, perforantes venocutáneas de la vena safena menor y perforantes neurocutáneas del nervio sural. El objetivo de este trabajo es describir la técnica quirúrgica y demostrar la versatilidad que tiene el colgajo peroneo posterior para la reconstrucción y cobertura de defectos del tercio distal de la pierna y el tercio proximal del pie, proporcionando el potencial para el cierre simple y eficiente de dichos defectos. Este colgajo proporciona grandes ventajas debido a que es reproducible en cualquier centro quirúrgico y no requiere un entrenamiento específico en microcirugía del cirujano y del resto del equipo quirúrgico. Si bien las complicaciones existen, la mayoría no son graves y en general son de resolución simple. En los últimos años, se ha incrementado el empleo del colgajo fasciocutáneo peroneo posterior para lograr la cobertura de los defectos de partes blandas del tercio distal de la pierna y pie. El éxito de estos colgajos está relacionado con el tipo de paciente y de su lesión: el porcentaje es alto en pacientes jóvenes y sanos en quienes el origen del defecto es traumático.


The posterior peroneal flap is a fasciocutaneous flap, which is based on 4 possible sources such as fasciocutaneous perforations of the peroneal artery, fasciocutaneous perforations of the posterior tibial artery, venocutaneous perforations of the saphenous vein, and neurocutaneous perforators of the sural nerve. The objective of this work is to describe the surgical technique and demonstrate the versatility of the posterior peroneal flap for the reconstruction and coverage of defects in the distal third of the leg and the proximal third of the foot, providing the potential for simple and efficient closure of said defects. It provides great advantages because it is reproducible in any surgical center and does not require specific training in microsurgery of the surgeon and the rest of the surgical team. Although complications do exist, most are not serious and are generally of simple resolution. In recent years, the use of the posterior peroneal flap has been increased to achieve coverage of soft tissue defects of the distal third of the leg and foot. The success of these flaps is related to the type of patient and his injury, the success rate is high in young and healthy patients in whom the origin of the defect is traumatic.

ABSTRACT

Luego del tratamiento quirúrgico de la patología maligna y premaligna de la región vulvoperineal nosenfrentamos al desafío de la reconstrucción del defecto de cobertura, el cual en la mayoría de los casos no puede resolverse con un cierre primario. Se presentan 2 casos de reconstrucción con colgajos locales con el objetivo de reparar el defecto, ofrecer un tejido vascularizado, el cual aporta mayor oxigenación, migración celular y un buen resultado estético ­ funcional. La reparación se realizó con colgajos de trasposición dependientes de la arteria pudenda y colgajos de avance y rotación del lado contralateral. Hemos concluido que la confección de colgajos locales en la región vulvar para la reconstrucción de defectos es una opción a tener en cuenta debido al aporte vascular, la presencia de perforantes dependientes de la arteria pudenda, la conservación nerviosa, el bajo índice de morbilidad y el aceptable resultado estético ­ funcional.


After the surgical treatment of the malignant and premalignant pathology of the vulvoperineal region we have the challenge of reconstruction the coverage defect, which in most cases cannot be resolved with a primary closure. We describe 2 cases of reconstruction with local fl aps, the aim is to repairing the defect, off ering a vascularized tissue, which provides more oxygenation, cell migration and a good aesthetic-functional result. The repair was performed with transposition fl aps dependent on the pudendal artery and advance and rotation fl aps of the contralateral side. We concluded that the repairwith local fl aps in the vulvar region for the reconstruction of defects is an option to take into account due to the vascular contribution, the presence of perforators dependent on the pudendal artery, nerve conservation, low morbidity index and acceptable aesthetic result - functional.

ABSTRACT

Abstract Introduction Reconstruction with a free flap is routine in head and neck surgery because of better functional outcomes, improved esthetics, and generally higher success rates. Objective To evaluate the clinical outcomes in patients undergoing different microvascular free flap reconstructions. Methods This was a retrospective study of 93 patients undergoing reconstructions with free flaps from 2007 to 2015. Four types of free flap were performed: anterolateral thigh (76.3%), radial forearm (16.1%), fibula (4.3%) and jejunum (3.3%). Patients' demographic data were collected, and the outcomes measured included flap survival and complications. Postoperative functional and oncological outcome were also analyzed. Results The patients included 73 men and 20 women, with a mean age of 56.1 years. The most common tumor location was the tongue. Squamous cell carcinoma represented the vast majority of the diagnosed tumors (89.2%). The most common recipient vessels were the superior thyroid artery (77.4%) and the internal jugular vein (91.4%). Nine patients required emergency surgical re-exploration and the overall flap success rate was 90.3%. Venous thrombosis was the most common cause for re-exploration. Other complications included wound infection (5.4%), wound dehiscence (1.1%), partial flap necrosis (9.7%), fistula formation (10.8%), and 1 bleeding (1.1%). The majority of patients had satisfactory cosmetic and functional results of both donor site and recipient site after 46.7 months of mean follow-up. Conclusion Microsurgical free flap is shown to be a valuable and reliable method in head and neck surgery. It can be used safely and effectively with minimal morbidity in selected patients. The reconstruction can be performed by appropriately skilled surgeons with acceptable outcomes. Success rate appears to increase as clinical experience is gained.


Resumo Introdução Reconstrução com retalhos livres é um procedimento de rotina nas cirurgias de cabeça e pescoço devido aos melhores resultados funcionais e estéticos e às taxas de sucesso geralmente maiores. Objetivo Avaliar os desfechos clínicos de pacientes submetidos a diferentes reconstruções microvasculares com retalhos livres. Método Estudo retrospectivo de 93 pacientes submetidos à reconstruções com retalhos livres, de 2007 a 2015. Foram utilizados quatro tipos de retalho livre: coxa anterolateral (76,3%), antebraço radial (16,1%), fíbula (4,3%) e jejuno (3,3%). Os dados demográficos dos pacientes foram coletados e os parâmetros avaliados incluíram sobrevida e complicações. Os resultados funcionais e oncológicos pós-operatórios também foram analisados. Resultados Os pacientes incluíram 73 homens e 20 mulheres, com idade média de 56,1 anos. O local mais comum para o tumor foi a língua. O carcinoma de células escamosas representou a maioria dos tumores diagnosticados (89,2%). As artérias receptoras mais comuns foram a artéria tireóidea superior (77,4%) e a veia jugular interna (91,4%). Nove pacientes necessitaram de reexploração cirúrgica de emergência e a taxa de sucesso global do retalho foi de 90,3%. A trombose venosa foi a causa mais comum da reexploração. Outras complicações incluíram infecção da ferida cirúrgica (5,4%), deiscência da ferida (1,1%), necrose parcial do retalho (9,7%), formação de fístula (10,8%) e sangramento (1,1%). A maioria dos pacientes apresentou resultados estéticos e funcionais satisfatórios, tanto no local doador quanto no receptor, após 46,7 meses de seguimento médio. Conclusão O retalho livre microcirúrgico mostrou ser um método valioso e confiável na cirurgia de cabeça e pescoço. Pode ser usado de forma segura e eficaz, com morbidade mínima em pacientes selecionados. A reconstrução pode ser feita por cirurgiões adequadamente qualificados com resultados aceitáveis. A taxa de sucesso parece aumentar à medida que a experiência clínica é adquirida.

ABSTRACT

O objetivo deste trabalho foi apresentar o relato de um caso clínico no qual uma paciente de 52 anos, com ausência de tecido queratinizado na região de rebordo do elemento 46, previamente extraído, foi submetida à cirurgia de enxerto gengival livre para criar uma faixa de tecido queratinizado, antes da instalação do implante osseointegrado. Após três meses de cicatrização, foi constatado signifi cativo ganho de tecido queratinizado na região, tornando o sítio mais favorável à reabilitação com implante dentário. Dessa forma, foi seguido o planejamento inicial e instalado um implante na região, que foi reabilitado posteriormente. Diversos trabalhos têm mostrado que o selamento biológico proporcionado por uma adequada faixa de tecido queratinizado ao redor de implantes seria um pré-requisito para a saúde e o sucesso desses implantes no longo prazo. A revisão clínica e radiográfi ca com três anos de acompanhamento mostrou estabilidade do tecido peri-implantar e, consequentemente, o sucesso do tratamento proposto.


The aim of this study was to present a clinical case report where a 52-year-old patient, with absence of keratinized tissue in the ridge region of the previously extracted element 46, received a free gingival graft surgery to create a tissue band before the osseointegrated implant installation. After 3 months of healing, a signifi cant gain of keratinized tissue was observed in the region, making the site more amenable to rehabilitation with a dental implant. In this way, the initial planning was followed and an implant was installed in the region and the restoration delivered afterwards. Several studies have shown that biological sealing provided by a suitable range of keratinized tissue around implants would be a prerequisite for the health and success of these implants in the long run. The clinical and radiographic review with 3 years of follow-up showed stability of the peri-implant tissue and, consequently, the success of the proposed treatment.

ABSTRACT

Os implantes imediatos têm sido utilizados com bastante frequência como uma forma de tratamento para a substituição de dentes condenados. Entretanto, quando a área a ser tratada pertence à zona estética, muito cuidado deve ser tomado. Nessa região, quando o objetivo é alcançar um peri-implante com estética satisfatória, o profissional deve utilizar técnicas que, associadas ao implante imediato, evitem a formação de um defeito decorrente da remodelação pós-exodontia, ou ainda, utilizar procedimentos de melhoria tecidual nos casos em que os dentes condenados já apresentem defeitos de tecido ósseo e/ou mole ao seu redor. O objetivo deste trabalho é, através da apresentação de um caso clínico de reposição do elemento 41 condenado, com perda óssea severa e defeito mucogengival, demonstrar e discutir uma modalidade de tratamento que utiliza o implante imediato de carga imediata não funcional associado ao enxerto de tecido conjuntivo e preenchimento com osso mineral bovino particulado.


Immediate implants have been used frequently as a treatment choice for the replacement of compromised teeth. However, when the area to be treated belongs to the aesthetic zone, great care must be exercised. In this region, when the objective is to reach a peri-implant with a satisfactory esthetics, the professional must use techniques that, associated to the immediate implant, prevent the formation of a defect due to the bone remodeling after tooth loss or to use procedures of tissue improvement for cases where the compromised teeth already have defects of bone and/or soft tissue around them. The objective of this study is to present a clinical case of replacement at tooth 41 with severe bone loss and mucogingival defect to demonstrate and discuss a treatment modality that uses the immediate implant with non-functional immediate loading associated with the connective tissue graft and particulate, deproteinized bovine bone filling.

ABSTRACT

Algumas das principais indicações para o recobrimento de superfícies radiculares expostas por recessão gengival compreendem a hipersensibilidade dentinária cervical e o tratamento de defeitos estéticos. Este trabalho descreveu o tratamento de recessão gengival múltipla classe III de Miller em um periodonto delgado, após 36 meses de uma intervenção cirúrgica com enxerto gengival livre. O tratamento cirúrgico periodontal proposto foi o recobrimento radicular por meio de enxerto de tecido conjuntivo subepitelial associado a retalho reposicionado coronalmente na região vestibular dos elementos 31, 41 e 42. Após 90 dias, foi possível observar o recobrimento parcial da recessão, aumento da espessura tecidual e o controle do biofi lme pelo paciente, promovendo maior proteção da região e redução do risco de recidiva das recessões. Diante da resolução do caso clínico apresentado, pôde-se concluir que a técnica do enxerto de tecido conjuntivo subepitelial associado ao retalho reposicionado coronalmente, quando bem indicada e realizada, pode ser empregada com sucesso em áreas de recessões múltiplas e periodonto com espessura reduzida.


Some of the main indications for the root coverage of gingival recessions include cervical dentin hypersensitivity and treatment of aesthetic defects. This manuscript describes the treatment of a Miller's Class III multiple gingival recession 36 months after a free gingival graft surgical procedure. The periodontal surgical treatment proposed was the subepithelial connective tissue graft associated with a coronally repositioned fl ap at vestibular region of elements 31, 41 and 42. After 90 postoperative days, it was possible to observe an increase on tissue thickness and biofi lm control by the patient, promoting a greater protection of the region and reducing the risk of recession recurrence. It can be concluded that the subepithelial connective tissue graft technique associated with the coronal repositioned fl ap, when well indicated and performed, can be successfully used in multiple recessions and periodontal regions with reduced thickness.

ABSTRACT

Recessão gengival corresponde à migração apical da margem gengival em relação à junção cemento/esmalte (JCE). A exposição da superfície radicular ­ uma consequência das recessões gengivais ­ pode causar hipersensibilidade dentinária, cárie radicular, discrepâncias de altura da margem gengival e consequentes defeitos estéticos ao paciente. Dentre as diversas opções de tratamento, os procedimentos cirúrgicos são as estratégias mais indicadas para correção desses defeitos gengivais. Para realizar este tipo de correção, é necessário classifi car esses defeitos, principalmente, quanto à perda de tecido interproximal e presença de mucosa ceratinizada apicalmente à margem gengival. Desta forma, o objetivo desse trabalho foi relatar um caso clínico de recobrimento radicular de múltiplas recessões classe I de Miller, utilizando a técnica de Bruno modifi cada, avaliando a redução das recessões gengivais, a reversão do quadro de hipersensibilidade dentinária e a satisfação estética relatada pelo paciente.


Gingival recession is the gingival margin migration related to the cemetum enamel junction. The root surface exposure, an outcome of gingival recession, may cause dentin hipersensibility, root caries, height variance of gingival margins causing aisthetic problems to the patient. Among the various treatment options, surgical procedures are the most suitable strategies for correction of these gingival defects. In order to perform this type of correction, it is necessary to classify these defects specially concerning about interdental tissue loss and presence of keratinized mucosa apically to the gingival margin. Therefore, the aim of this work was to report a clinical case of root coverage Miller Class I multiple recessions, using the modifi ed Bruno technique, evaluating the gingival recession, reversion of dentin hypersensitivity, and the aesthetic satisfaction reported by the patient.

ABSTRACT

A recessão gengival está frequentemente associada à lesão cervical não cariosa (LCNC), originando uma lesão combinada que tem um prognóstico de tratamento diferente de quando as duas lesões se apresentam sozinhas. Tratamentos propostos possuem limitações, e o protocolo clínico ideal para o manejo dessas lesões ainda não foi estabelecido. Assim, o objetivo do presente relato de caso foi apresentar uma nova técnica cirúrgico-restauradora para o tratamento de recessões gengivais associadas à LCNC. Para tal, uma restauração parcial em resina composta foi realizada somente na parte coronal da lesão cervical. Em uma segunda sessão, o procedimento cirúrgico para recobrimento radicular com enxerto de tecido conjuntivo foi realizado. Seis meses após o procedimento, a paciente estava satisfeita com o resultado final alcançado, demonstrando que esse protocolo pode ser uma alternativa de tratamento aos protocolos existentes para o tratamento de recessões gengivais associadas à LCNC.


Gingival recession is often associated with non-carious cervical lesion (NCCL), resulting in a combined lesion which has a different treatment prognosis when the two lesions appear alone. Proposed treatments have limitations and the ideal clinical protocol for the management of these lesions has not been established. Thus, the aim of this case report is to present a new surgical-restorative technique for the treatment of gingival recessions associated with NCCL. For this, a composite resin partial restoration was performed only in the coronal part of the cervical lesion. In a second session, the surgical procedure for root coverage with connective tissue graft was performed. Six months after the procedure, the patient was satisfied with the final result achieved, demonstrating that this protocol may be an alternative to the existing protocols for the treatment of gingival recessions associated with NCCL.

ABSTRACT

O objetivo deste artigo foi relatar um caso clínico no qual foi realizada uma modificação da técnica de estabilização do enxerto de tecido conjuntivo (ETC) concomitante à etapa de reabertura, com o intuito de melhorar a qualidade da mucosa peri-implantar na região lingual posterior de mandíbula. Após anamnese, foi constatada no exame clínico a necessidade de exodontia do dente 34 e reabilitação protética na região do 34-36. Após cinco meses, foram instalados três implantes na região dos dentes 34, 35 e 36. Decorridos quatro meses, foi realizada a reabertura desses implantes e, pela ausência de mucosa queratinizada na região dos implantes instalados, optou-se por realizar um ETC na região lingual do 35 e 36. Este foi removido do palato e, para melhor adaptação desse enxerto no leito receptor, foi utilizado um perfurador de lençol de borracha para perfurar o ETC no local que correspondia aos cicatrizadores dos implantes 35 e 36, estabilizando-se assim o ETC no leito receptor. O retalho foi reposicionado, cobrindo totalmente o ETC e suturado. Após três anos, o tecido mole adjacente ao implante apresentava-se clinicamente estável e saudável, e a paciente encontrava-se satisfeita com o resultado. De acordo com o caso clínico relatado, esta nova abordagem para utilização do ETC, para criar uma faixa de gengiva queratinizada ao redor de implantes, mostrou-se efi ciente quanto à sua utilização de região posterior de mandíbula. Entretanto, estudos clínicos adicionais são necessários para avaliar a precisão desta técnica em outras condições clínicas.


The aim of this article is to report a clinical case where a modification of the technique of stabilization of the connective tissue graft concomitant to the reopening stage was performed in order to improve the quality of the periimplantar mucosa in the posterior lingual region of the mandible. After anamnesis, and clinical examination, the need to perform tooth 34 extraction and prosthetic rehabilitation in the region 34-36 was verifi ed. After 5 months, 3 implants were installed in the region of teeth 34, 35 and 36. After 4 months, the reopening of these implants was performed and because of the absence of keratinized mucosa in the region of the implants it was chosen to perform a connective tissue graft (CTG) in the lingual region of 35 and 36. The graft removed from the palate and for better adaptation bed, a rubber sheet punch was used to puncture it at the site corresponding to the implants 35 and 36 being stabilized in the recipient bed. The flap was repositioned, completely covering the CTG and sutured. After 3 years, the soft tissue adjacent to the implant was clinically stable, healthy and the patient was satisfied with the result. According to the reported clinical case, this new approach for the use of CTG to create a keratinized gingival band around implants proved to be efficient in its use of the posterior mandible region. However, additional clinical studies are needed to assess the accuracy of this technique in other clinical conditions.

ABSTRACT

Objetivo: Evaluar el uso de una sonda Doppler para verificar la permeabilidad y el flujo de la anastomosis en colgajos microquirúrgicos. Material y método: Serie descriptiva prospectiva de los pacientes en los cuales se realizó reconstrucción con colgajo microquirúrgico en la Clínica Alemana entre marzo de 2013 y marzo de 2015, en los cuales se utilizó un monitor Doppler arterial postanastomótico (Coock® Swartz Doppler probe). Resultados: Se registraron 20 pacientes con colgajos microquirúrgicos. Se realizaron 10 colgajos antebraquiales, 7 fíbulas (4 con testigo cutáneo y 3 sin), 2 anterolaterales de muslo y uno recto abdominal. Se realizaron 6 reexploraciones en pabellón. En un caso hubo sospecha tanto clínica como por el cambio en la señal del Doppler; en 4 solo sospecha clínica, y en uno solo por cambio en la señal Doppler. Los hallazgos fueron edema del colgajo en un paciente y 5 hematomas. No hubo pérdida de colgajos. Se utilizó el monitor Doppler por un promedio de 9,5 días. Conclusión: Este método de evaluación no reemplaza a la observación cínica, pero representa una herramienta más para la toma de decisiones en el postoperatorio de este tipo de reconstrucciones en cabeza y cuello.


Aim: To evaluate Doppler probe to assure the flow through the anastomoses at free flaps used in head and neck surgery. Material and method: Descriptive prospective series, of every patient that receive a free flap reconstruction at Clinica Alemana between March 2013 and March 2015, in which a Doppler monitor (Coock® Swartz Doppler probe) on the arterial anastomoses was used. Results: 20 patients with free flaps were recorded. 10 radial flaps, 7 fibulas (4 with a skin paddle and 3 without), 2 antero lateral thigh flaps and 1 abdominis rectus flap. 6 reexplorations were done. In one case the suspicion was clinical, with change in the Doppler signal, 4 patients just clinical suspicion and 1 just because a change in the Doppler signal. The findings were flap edema in 1 patient and 5 hematomas. We didn’t loss any flap. The Doppler monitor was used for an average of 9.5 days. Conclusion: The Doppler monitor doesn’t replace the clinical observation but represents another tool for the decision making during the post operative period in this kind of head and neck reconstructions.

ABSTRACT

Feridas de grandes extensões, com perda da viabilidade tecidual e retardo na cicatrização por segunda intenção são casos que se faz necessário o emprego de técnicas cirúrgicas reconstrutivas. O plasma rico em plaquetas (PRP) é um produto com maior concentração plaquetária, adjuvante no processo cicatricial de cirurgias reconstrutivas, auxiliando nos processos de hemostasia e estimulação da angiogênese. Dessa forma, delineou-se um estudo a fim de avaliar a eficácia do uso do gel produzido a partir do plasma rico em plaquetas (PRP) em flapes de avanço de padrão axial toracodorsal em coelhos, para avaliar a possibilidade de favorecer a integração do retalho no leito receptor. Utilizaram-se 30 coelhos da raça Nova Zelândia branco, separados em dois grupos de 15 animais, compreendendo os grupos plasma rico em plaquetas (GPRP), na qual empregou-se o gel antes da síntese da ferida cirúrgica, e controle (GC), na qual utilizou-se apenas solução fisiológica. Para obtenção do PRP, coletou-se sangue dos animais, e determinou-se a contagem plaquetária antes da preparação do gel. No início e término do experimento os animais foram pesados para posterior análise de ganho peso médio. Após o procedimento cirúrgico iniciou-se as avaliações macroscópicas no 3º, 7º e 14º dia, e avaliou-se presença ou ausência de exsudato, integridade da pele, edema, rubor e necrose. Após esta etapa, coletou-se o material da ferida cirúrgica para confecção das lâminas histológicas e posterior avaliação microscópica. Avaliou-se a proliferação vascular, presença de células mononucleares e polimorfonucleares, proliferação fibroblástica, colagenização, reepitelização e hemorragia. Os dados obtidos foram submetidos à análise estatística (Teste t Student, t emparalhado, e Kruskall Walis, sendo p<0,05)[...]


Wounds of large tracts with loss of tissue viability and delayed healing by secondary intention are cases where it is necessary the use of reconstructive surgical techniques. The platelet rich plasma (PRP) is a product with a higher platelet concentration, adjuvant in the healing process of reconstructive surgeries, assisting in the processes of hemostasis and stimulation of angiogenesis. Thus, a study was devised to assess the efficacy of the gel produced from the platelet rich plasma (PRP) in the forward axial flaps thoracodorsal pattern in rabbits to evaluate the ability to promote the integration of the flap the recipient bed. We used 30 white rabbits New Zealand, separated into two groups of 15 animals, comprising the platelet rich plasma groups (GPRP), in which we used the gel before the synthesis of the surgical wound , and control (CG), in which only saline was used. To obtain the PRP, the blood was collected from the animals, was determined and the platelet count before preparation of the gel. At the beginning and end of the experiment the animals were weighed for analysis of average weight gain.

ABSTRACT

Introduction: The most commonly used flaps for the reconstruction of the lower eyelid and malar/palpebral groove are cervicofacial flaps owing to their horizontal traction, which results in a lower risk of ectropion and canthal dystopias. V-Y skin flap is not often used for the fear of the vertical traction being transferred to the lower eyelid, which would lead to the occurrence of ectropion and dystopias. Our aim is to demonstrate that, if well executed, this flap may be a good option for reconstructions of this region. Methods: Sixty-eight eyelid reconstructions have been performed at the ACCamargo Cancer Center between December 2012 and May 2015. Of these, 29 patients underwent reconstruction of the lower eyelid or malar/palpebral groove using a V-Y skin flap after skin tumor removal. Results: Among the palpebral reconstructions, the most commonly used was the V-Y flap (29 cases, 42.6%). Two cases (6.9%) developed ectropion. No case of seroma, hematoma, infection, or partial loss of the flap has been observed. Conclusion: The V-Y flap is a good option for eyelid reconstruction when well indicated, designed, and executed, since it presents low complication rates and the possibility to be performed under local anesthesia. Therefore, this flap is a good choice for patients without the clinical conditions necessary to undergo surgery under general anesthesia.


Introdução: Os retalhos mais comumente utilizados para reconstruções de pálpebra inferior e junção malar/palpebral são os cervicofaciais, pois a sua tração horizontal levaria a menor risco de ectrópio e distopias cantais. O retalho cutâneo em V-Y frequentemente não é utilizado pelo receio de que a tração vertical seja transferida à pálpebra inferior, gerando ectrópio e distopias. Nosso objetivo é demonstrar que, se bem executado, este retalho pode ser uma boa opção para reconstruções nesta região. Métodos: Foram realizadas 68 reconstruções palpebrais no ACCamargo Cancer Center, entre dezembro de 2012 e maio de 2015. Dentre estes pacientes, 29 foram submetidos à reconstrução de pálpebra inferior ou junção malar/palpebral, após ressecção de tumores cutâneos, com retalhos cutâneos em V-Y. Resultados: Dentre as reconstruções palpebrais, o retalho V-Y foi o mais utilizado (29 casos, 42,6%). Dois casos (6,9%) evoluíram com ectrópio. Não houve nenhum caso de seroma, hematoma, infecção ou perda parcial do retalho. Conclusão: O retalho V-Y é uma boa opção para reconstruções palpebrais quando bem indicado, desenhado e executado, pois apresenta baixos índices de complicações e também por poder ser realizado sob anestesia local, sendo uma boa escolha para pacientes sem condições clínicas de serem submetidos à anestesia geral.

ABSTRACT

OBJECTIVE: In gracilis functioning free muscle transplantation, the limited caliber of the dominant vascular pedicle increases the complexity of the anastomosis and the risk of vascular compromise. The purpose of this study was to characterize the results of using a T-shaped vascular pedicle for flow-through anastomosis in gracilis functioning free muscle transplantation for brachial plexus injury. METHODS: The outcomes of patients with brachial plexus injury who received gracilis functioning free muscle transplantation with either conventional end-to-end anastomosis or flow-through anastomosis from 2005 to 2013 were retrospectively compared. In the flow-through group, the pedicle comprised a segment of the profunda femoris and the nutrient artery of the gracilis. The recipient artery was interposed by the T-shaped pedicle. RESULTS: A total of 46 patients received flow-through anastomosis, and 25 patients received conventional end-to-end anastomosis. The surgical time was similar between the groups. The diameter of the arterial anastomosis in the flow-through group was significantly larger than that in the end-to-end group (3.87 mm vs. 2.06 mm, respectively, p<0.001), and there were significantly fewer cases of vascular compromise in the flow-through group (2 [4.35%] vs. 6 [24%], respectively, p=0.019). All flaps in the flow-through group survived, whereas 2 in the end-to-end group failed. Minimal donor-site morbidity was noted in both groups. CONCLUSIONS: Flow-through anastomosis in gracilis functioning free muscle transplantation for brachial plexus injury can decrease the complexity of anastomosis, reduce the risk of flap loss, and allow for more variation in muscle placement. .

ABSTRACT

INTRODUÇÃO: A reconstrução do complexo areolopapilar (CAP) constitui o passo final na criação da neomama, com o objetivo de aproximá-la da mama contralateral após a mastectomia. A restauração do CAP tem sido historicamente um procedimento feito em estágios, com a reconstrução da papila realizada por meio de enxertos ou retalhos locais, previamente, e da aréola, posteriormente, buscando a coloração adequada. Atualmente, a utilização da tatuagem areolar está alcançando popularidade cada vez maior, comparativamente às técnicas tradicionais. O objetivo deste trabalho é descrever a técnica e os equipamentos utilizados para a tatuagem intradérmica em pacientes mastectomizadas, realizada no Serviço de Cirurgia Plástica e Microcirurgia Reconstrutiva do Hospital Universitário Walter Cantídio (Fortaleza, CE, Brasil). MÉTODO: O presente trabalho descreve os passos para a realização do procedimento reparador utilizando a tatuagem areolar permanente com equipamento convencional de tatuagem artística profissional. O procedimento foi aplicado em 10 pacientes submetidas a reconstrução mamária pós-mastectomia. RESULTADOS: O método demonstrou as vantagens da simplicidade técnica do procedimento, não requerendo internamento nem resultando em morbidade de áreas doadoras. CONCLUSÕES: A tatuagem do CAP é um procedimento seguro, rápido, com baixa morbidade e bons resultados na finalização da reconstrução mamária.


BACKGROUND: The final step in the creation of the neo-breast is reconstruction of the nipple-areolar complex (NAC), which is aimed toward bringing the appearance of the NAC closer to that of the contralateral breast following mastectomy. NAC restoration has historically been a stepwise procedure, in which reconstruction of the nipple by the use of grafts or local flaps was followed by reconstruction of the areola to achieve the correct color. Currently, the popularity of the areolar tattoo is increasing compared to traditional techniques. The aim of this study was to describe the technique and equipment used for intra-dermal tattooing in mastectomized patients at the Plastic Surgery and Reconstructive Microsurgery Service of the Walter Cantídio University Hospital (Fortaleza, CE, Brazil). METHODS: This study describes the steps of the repair procedure by using permanent areolar tattooing with conventional equipment from a professional tattoo artist. The procedure was used in 10 patients undergoing post-mastectomy breast reconstruction. RESULTS: The advantages of this method included the technical simplicity of the procedure, the ability to use this procedure in outpatients, and the lack of morbidity of the donor areas. CONCLUSIONS: Tattooing the NAC is a safe, fast procedure with low morbidity and good results of breast reconstruction.

ABSTRACT

One of the main purposes of mucogingival therapy is to obtain full root coverage. Several treatment modalities have been developed, but few techniques can provide complete root coverage in a class III Miller recession. Thus, the aim of this case report is to present a successful clinical case of a Miller class III gingival recession in which complete root coverage was obtained by means of a multidisciplinary approach. A 17-year-old Caucasian female was referred for treatment of a gingival recession on the mandibular left central incisor. The following procedures were planned for root coverage in this case: free gingival graft, orthodontic movement by means of alignment and leveling and coronally advanced flap (CAF). The case has been followed up for 12 years and the patient presents no recession, no abnormal probing depth and no bleeding on probing, with a wide attached gingiva band. A compromised tooth with poor prognosis, which would be indicated for extraction, can be treated by orthodontic movement and periodontal therapy, with possibility of 100% root coverage in some class III recessions.


Um dos principais objetivos da terapia mucogengival é atingir a cobertura completa da raiz. Diversas modalidades de tratamento têm sido desenvolvidas, mas poucas técnicas podem obter a cobertura total da raiz em uma recessão gengival classe III de Miller. Assim, o objetivo deste relato é apresentar um caso de sucesso clínico de uma recessão gengival classe III de Miller na qual foi obtida a cobertura completa da raiz por meio de uma abordagem multidisciplinar. Uma jovem de 17 anos sexo feminino, leucoderma, foi encaminhada para tratamento de uma recessão gengival no incisivo central inferior esquerdo. Para a cobertura radicular foi planejado: enxerto gengival livre, movimento ortodôntico por meio de alinhamento e nivelamento e retalho reposicionado coronariamente (CAF). Este caso tem sido acompanhado por 12 anos e o paciente apresenta ausência de recessão, sem profundidade de sondagem anormal e sem sangramento à sondagem com ampla faixa de gengiva inserida. Dentes comprometidos e com mau prognóstico, que seriam extraídos em muitos casos, podem ser tratados por meio de movimento ortodôntico e terapia periodontal. 100% de cobertura da raiz é possível e pode ser conseguida em alguns casos de recessão gengival classe III.

ABSTRACT

The authors report a variation of Poland's syndrome with ectopic right breast. Three surgeries were performed at different times: transposition flap to place the mammary gland in an anatomic position; reduction of the contralateral left breast; and implantation of a pre-molded silicone prosthesis to correct the malformation caused by the absence of the major and minor pectoral muscles. The surgeries were performed at six-month intervals, and the final outcome was new and acceptable positioning of the breasts.


Os autores apresentam uma variante da síndrome de Poland com mama direita ectópica. Foram realizados três tempos cirúrgicos: retalho de transposição para colocação da glândula mamária em posição anatômica; redução da mama contralateral esquerda; e implantação de prótese de silicone pré-moldada para correção do defeito causado pela agenesia dos músculos peitoral maior e peitoral menor. Com intervalo de seis meses entre as cirurgias, o resultado final apresenta novo posicionamento aceitável das mamas.
