ABSTRACT

Introdução: O número crescente de pacientes com perda ponderal maciça, após cirurgias bariátricas, correlaciona-se com a procura por cirurgias de contorno corporal. Tais procedimentos reduzem queixas físicas e psicológicas, influenciando positivamente a qualidade de vida dessas pessoas. Todavia, há poucos dados quanto à resposta dos serviços que oferecem tratamento cirúrgico para obesidade mórbida frente a essa necessidade. O estudo tem como objetivo aferir a prevalência de cirurgia do contorno corporal entre 2015 e 2018, em pacientes previamente submetidos à cirurgia bariátrica, nos anos de 2014 e 2015, em um hospital universitário. Métodos: Consulta ao sistema de informação hospitalar e a prontuários médicos a fim de aferir prevalência institucional de cirurgia de contorno corporal pós-bariátrica. Foram excluídos pacientes que não tenham sido submetidos a ambas as cirurgias em nosso Serviço, os que realizaram os referidos procedimentos cirúrgicos em outros anos, bem como aqueles com registros incompletos. Resultados: Foram realizadas cirurgias bariátricas em 208 pacientes. Desses, 11% (n=23) foram submetidos a 27 cirurgias do contorno corporal, sendo a dermolipectomia abdominal (n=16) a mais realizada. A realização de mais de um procedimento para correção de deformidade corporal ocorreu em 13% (n=3) dos pacientes. A média de idade dos pacientes submetidos a cirurgia do contorno corporal foi de 37 anos, a maioria do sexo feminino (96%, n=22). Conclusão: A cirurgia do contorno corporal constitui etapa importante do tratamento da obesidade mórbida e tem caráter reparador. Há imensa carência dessa terapêutica, o que compromete irremediavelmente os resultados obtidos pela cirurgia bariátrica.


Introduction: The growing number of patients with massive weight loss after bariatric surgery is correlated with the demand for body contouring surgery. Such procedures reduce physical and psychological complaints, positively influencing the quality of life of these people. However, there is little data on the response of services that offer surgical treatment for morbid obesity to this need. The study aims to measure the prevalence of body contouring surgery between 2015 and 2018, in patients previously underwent on a bariatric surgery, in 2014 and 2015, at a University Hospital. Methods: Research in the hospital information system and medical records in order to assess the institutional prevalence of post-bariatric body contouring surgery. Patients who did not undergo both surgeries in our Service, those who underwent these surgical procedures in other years, as well as those with incomplete medical records were excluded. Results: Bariatric surgeries were performed in 208 patients. Of these, 11% (n=23) underwent 27 body contouring surgeries, with abdominal dermolipectomy (n=16) being the most frequently performed. The performance of more than one procedure to correct body deformity occurred in 13% (n=3) of patients. The mean age of patients undergoing body contouring surgery was 37 years, the majority was female (96%, n=22). Conclusion: Body contouring surgery is an important step in the treatment of morbid obesity and has a restorative feature. There is a huge lack of this therapy, which irreparably compromises the results obtained by bariatric surgery.

ABSTRACT

Introdução: A lipoenxertia consiste no processo de coleta de gordura de uma área doadora de gordura por meio de lipoaspiração seguida da realocação desse tecido em área receptora por meio de seringas e cânulas. É um processo seguro utilizado em cirurgias estéticas e reconstrutivas, de acordo com a literatura. O objetivo é avaliar as taxas de complicações dos procedimentos de lipoenxertia realizados em um hospital público universitário no período de 2015 a 2018, em comparação com dados previamente relatados na literatura. Métodos: Estudo observacional retrospectivo desenvolvido em hospital universitário público de Campinas - SP a partir da revisão de prontuários de pacientes submetidos a lipoenxertia nesta instituição de 2015 a 2018. Resultados: Em relação às complicações, a grande maioria correspondeu à reabsorção de gordura (62%). O hematoma correspondeu ao segundo mais comum (38% dos casos), seguido do edema (19%). Dor e discromia vieram em seguida, com 10% e 7% dos casos, respectivamente. Apenas um caso de infecção de ferida operatória foi descrito. Outras complicações menos frequentes foram hiperemia (5%), assimetrias (5%), descamação (2%), parestesia local (3%) e lesão cutânea (2%). Nenhuma outra complicação maior foi relatada, como embolia gordurosa ou complicações cirúrgicas graves como sangramento, sepse, anafilaxia, entre outras. Conclusão: Os procedimentos de lipoaspiração para coleta de gordura e lipoenxertia mostraram-se seguros e com baixo índice de complicações na amostra estudada, concordando com dados da literatura.


Introduction: Fat grafting consists of collecting fat from one fat donor area via liposuction, then reallocating this tissue into a receptor area through syringes and cannulas. According to the literature, it is a safe process used in aesthetic and reconstructive surgeries. The objective is to evaluate complication rates of fat grafting procedures performed in a public university hospital from 2015 to 2018 in comparison with data previously reported in the literature. Methods: A retrospective observational study developed at a public university hospital in Campinas-SP based on the revision of medical records of patients who underwent the fat grafting procedure in this institution from 2015 to 2018. Results: Regarding the complications, the vast majority corresponded to fat reabsorption (62%). Bruise corresponded to the second most common (38% of cases), followed by edema (19%). Pain and dyschromia followed next, with 10% and 7% of cases, respectively. Only one case of operative wound infection was described. Other less frequent complications included hyperemia (5%), asymmetries (5%), desquamation (2%), local paraesthesia (3%) and skin lesion (2%). No other larger complication was reported, such as fat embolism or severe surgical complications such as bleeding, sepsis, or anaphylaxis. Conclusion: The procedures of liposuction for fat collection and fat grafting were proved to be safe, yielding low complication rates in the studied sample, which agrees with data reported in the literature.

ABSTRACT

Abstract Purpose To evaluate whether silicone foam implants have a different evolution pattern compared to conventional texture implants. Methods Fifty-eight female patients underwent surgery. They were divided into two groups (silicone foam - Lifesil® - and microtexturized silicone - Lifesil®). The evolution was analyzed in postoperative consultations, with physical examination, photographic documentation and filling in a satisfaction questionnaire, in the postoperative period of one month, four months, one year and then annually, up to a maximum of 3 years of follow-up. Results There were no statistically significant differences in presence of rippling, stretch marks, breast ptosis, capsular contracture and quality of scars. There was a higher rate of patients who were very satisfied with the outcome 360 days after surgery in the group receiving silicone foam implants (p = 0.036). Conclusion In short time, silicone foam envelope implants proved to be as reliable as textured silicone envelope implants, making them an option for augmentation mammoplasty.

ABSTRACT

ABSTRACT CONTEXT: Lymphedema consists of extracellular fluid retention caused by lymphatic obstruction. In chronic forms, fat and fibrous tissue accumulation is observed. Genital lymphedema is a rare condition in developed countries and may have primary or acquired etiology. It generally leads to urinary, sexual and social impairment. Clinical treatment usually has low effectiveness, and surgical resection is frequently indicated. CASE REPORT: We report a case of a male-to-female transgender patient who was referred for treatment of chronic genital lymphedema. She had a history of pelvic radiotherapy to treat anal cancer and of liquid silicone injections to the buttock and thigh regions for esthetic purposes. Radiological examinations showed signs both of tissue infiltration by liquid silicone and of granulomas, lymphadenopathy and lymphedema. Surgical treatment was performed on the area affected, in which lymphedematous tissue was excised from the scrotum while preserving the penis and testicles, with satisfactory results. Histopathological examination showed alterations compatible with tissue infiltration by exogenous material, along with chronic lymphedema. CONCLUSION: Genital lymphedema may be caused by an association of lesions due to liquid silicone injections and radiotherapy in the pelvic region. Cancer treatment decisions for patients who previously underwent liquid silicone injection should take this information into account, since it may represent a risk factor for radiotherapy complications.


RESUMO CONTEXTO: O linfedema consiste de retenção de fluido extracelular causada por obstrução linfática. Nas formas crônicas, observa-se acúmulo de tecido adiposo e fibrose. O linfedema genital é uma doença rara em países desenvolvidos e pode ter etiologia primária ou adquirida, em geral cursando com disfunções urinária e sexual, bem como com prejuízo do convívio social. O tratamento clínico é, em geral, pouco efetivo, indicando-se com frequência a abordagem cirúrgica, com excisão da área afetada. RELATO DE CASO: Relata-se o caso de paciente feminina transgênero, encaminhada para tratamento de linfedema genital crônico. Havia antecedente pessoal de tratamento de câncer de canal anal com radioterapia pélvica e de injeções de silicone líquido em glúteos e coxas com finalidade estética. Exames radiológicos mostraram tanto sinais de infiltração tecidual por silicone líquido como granulomas e linfadenopatia como de linfedema. Foi realizado o tratamento cirúrgico da área afetada, com excisão do tecido linfadenomatoso do escroto, preservando o pênis e testículos, com resultado satisfatório. A análise histopatológica mostrou achados compatíveis com infiltração tecidual por material exógeno, bem como com linfedema crônico. CONCLUSÃO: O linfedema genital pode ser causado pela associação de lesão por injeção de silicone líquido e radioterapia na região pélvica. As decisões no tratamento de neoplasias em pacientes previamente submetidos a injeção de silicone líquido devem levar em conta esse fato, já que pode representar fator de risco para complicações de tratamento radioterápico.

ABSTRACT

INTRODUÇÃO: A proeminência dos pavilhões auriculares é a forma mais comum de deformidade desta estrutura, afetando em torno de 5% da população. A maioria dos trabalhos acerca da cirurgia de otoplastia apresenta avaliações subjetivas, não permitindo apreciar acuradamente os resultados no pós-operatório, bem como dificultando a comparação entre técnicas. Propõe-se o desenvolvimento e aplicação de protocolo específico para avaliação dos resultados. MÉTODO: Avaliação prospectiva pelo período de um ano de pacientes submetidos à otoplastia bilateral utilizando técnica baseada em modelagem cartilaginosa com suturas, utilizando medidas da distância hélice-mastoide em pontos padronizados. RESULTADOS: Foram operados 23 pacientes com idade média de 17,8 anos. A incidência de reoperação foi de 21,7% dos pacientes ou 10,7% das orelhas. Houve perda de cerca de 45% da correção obtida no ponto superior e 35% nos pontos médio e inferior nos pacientes não reoperados. CONCLUSÕES: O protocolo foi de fácil utilização e permitiu a avaliação objetiva tanto da deformidade no pré-operatório quanto dos resultados cirúrgicos. A técnica utilizada produziu resultados considerados adequados e comparáveis aos da literatura.


INTRODUCTION: Prominence is the most common deformity of the ear, affecting about 5% of the population. Most reports on otoplasty describe subjective evaluations, and do not provide accurate postoperative assessment or a comparison between techniques. We propose the development and implementation of a specific protocol to evaluate results. METHOD: A prospective evaluation for a period of one year in patients who underwent bilateral otoplasty was performed, using a technique based on modeling of the cartilage with sutures, and helix-to-mastoid distance measurements at standardized points. RESULTS: A total of 23 patients with an average age of 17.8 years underwent surgery. Reoperation was performed in 21.7% of the patients or 10.7% of the ears. Nearly 45% of the correction obtained at the upper point and 35% at the middle and lower points were lost in patients who did not undergo reoperation. CONCLUSIONS: The protocol was easily used and allowed objective evaluation of the preoperative deformity and surgical results. This technique produced results considered adequate and comparable to the literature.

ABSTRACT

PURPOSE : To evaluate the effect of different energies and stacking in skin shrinkage. METHODS : Three decreasing settings of a fractional CO2 laser were applied to the abdomen of Twenty five Wistar rats divided into three groups. Group I (n=5) was histologically evaluated for microthermal zones dimensions. Groups II and III (n=10 each) were macroscopic evaluated with freeware ImageJ for area contraction immediately and after 30 and 60 days. RESULTS : No statistical significance was found within microthermal zone histological dimensions (Group I) in all settings studied. (Ablation depth: 76.90 to 97.18µm; Coagulation depth: 186.01 to 219.84 µm). In Group II, macroscopic evaluation showed that all settings cause significant immediate skin contraction. The highest setting cause significant more intense tightening effect initially, contracting skin area from 258.65 to 179.09 mm2. The same pattern was observed in Group III. At 30 and 60 days, the lowest setting significantly sustained contraction. CONCLUSION : Lower fractional CO2 laser energies associated to pulse stacking could cause consistent and long lasting tissue contraction in rats.

ABSTRACT

PURPOSE: To investigate the osseointegration properties of prototyped implants with tridimensionally interconnected pores made of the Ti6Al4V alloy and the influence of a thin calcium phosphate coating. METHODS: Bilateral critical size calvarial defects were created in thirty Wistar rats and filled with coated and uncoated implants in a randomized fashion. The animals were kept for 15, 45 and 90 days. Implant mechanical integration was evaluated with a push-out test. Bone-implant interface was analyzed using scanning electron microscopy. RESULTS: The maximum force to produce initial displacement of the implants increased during the study period, reaching values around 100N for both types of implants. Intimate contact between bone and implant was present, with progressive bone growth into the pores. No significant differences were seen between coated and uncoated implants. CONCLUSION: Adequate osseointegration can be achieved in calvarial reconstructions using prototyped Ti6Al4V Implants with the described characteristics of surface and porosity. .

ABSTRACT

Introdução: Com o crescente aumento do tratamento cirúrgico da obesidade, surge para o cirurgião plástico um grupo de pacientes com grande flacidez cutânea após perda ponderal. Para aqueles submetidos à gastroplastia redutora convencional ou aberta, a abdominoplastia vertical, em âncora ou em T invertido, tem sido largamente utilizada para a melhoria do contorno abdominal, e no presente trabalho foi associada à amputação umbilical seguida de neo-onfaloplastia. Método: Foram operados 70 pacientes, com peso estável há no mínimo 18 meses, procedentes do ambulatório de Cirurgia Plástica da UNICAMP, no período de março de 2011 a abril de 2013. Em todos foi utilizada a técnica de abdominoplastia em âncora com exérese do umbigo original, juntamente com a peça cirúrgica e confecção de neo-umbigo, através de retalhos dermo-gordurosos bilaterais. Procedeu-se à análise retrospectiva dos prontuários médicos e arquivo fotográfico dos mesmos. Resultados: Nos 70 pacientes operados, houve predominância do sexo feminino (91%) e da raça branca (83%), com média de 40 anos. Após tempo de espera de aproximadamente 16 meses, foram submetidos à abdominoplastia em âncora associada a neo-onfaloplastia, que durou em média 2 horas. Observaram-se complicações pós-operatórias em 29,85% - deiscências pequenas, cicatrizes inestéticas, alargadas ou hipertróficas, queloides, seromas, excessos dermo-gordurosos relevantes e infecção de ferida operatória. Os neoumbigos obtidos são muito semelhantes aos umbigos originais. Não observamos necroses, estenoses, distorções morfológicas e nem mau posicionamento dos mesmos. Conclusão: Esta técnica tem permitido a obtenção de umbigos com aspecto natural, é de fácil execução e reduz o tempo operatório.


Introduction: With the increasing surgical treatment of obesity, a new group of patients is being attended by plastic surgeons: those with large flaccid skin following weight loss. For patients treated with conventional or open bariatric surgery, vertical, anchorline, or inverted "T" abdominoplasty has been widely used to improve the abdominal contour. In this study, abdominoplasty was associated with umbilical amputation followed by neo-omphaloplasty. Methods: Seventy patients with stable weight for at least 18 months underwent surgery at the UNICAMP Plastic Surgery Outpatient Clinic, from March 2011 to April 2013. In all patients, anchor-line abdominoplasty with excision of the original navel was executed, together with the surgical specimen and preparation of neo-umbilicus, through bilateral dermal-fat flaps. A retrospective analysis of medical records and photographic archives was performed. Results: The 70 patients were predominantly female (91%) and white (83%) with a mean age of 40 years. After a wait time of approximately 16 months, they were subjected to anchorline abdominoplasty associated with neo-omphaloplasty, which lasted an average of 2 hours. There were post-operative complications in 29.85% of the patients, including small dehiscence, unsightly, enlarged, or hypertrophic scars, keloid, seroma, relevant dermo-fatty excesses, and wound infection. The neo-umbilicus obtained from the surgery is very similar to the original umbilicus. We did not observe necrosis, stenosis, morphological distortions, or bad positioning. Conclusion: This technique has made it possible to obtain an umbilicus with a natural look, is easy to perform, and shortens operating time.

ABSTRACT

INTRODUÇÃO: As fraturas nasais são lesões de grande incidência, frequentemente consideradas de menor importância. No entanto, podem trazer prejuízos importantes do ponto de vista tanto funcional como estético. MÉTODO: Foram analisados prontuários médicos de 144 pacientes submetidos a tratamento de fratura nasal na Área de Cirurgia Plástica do Hospital de Clínicas da Unicamp, no período de fevereiro de 2002 a outubro de 2008. RESULTADOS: Observou-se predomínio de pacientes do gênero masculino (75,7 por cento), com proporção entre gêneros masculino e feminino de 3,1:1. A faixa etária mais acometida foi aquela entre 21 anos e 30 anos de idade. A maioria das fraturas (31,8 por cento) foi causada por agressão física. Todos os pacientes foram tratados por meio de redução fechada, sob anestesia local e tópica, após um período médio de 8 dias. Entre os pacientes analisados, 13 evoluíram com deformidade residual. CONCLUSÕES: O paciente tipicamente afetado pelas fraturas nasais é o indivíduo adulto jovem e do gênero masculino. O tratamento cirúrgico por meio de redução fechada promove resultados aceitáveis, se respeitados os princípios de avaliação correta da lesão e do momento de indicação do tratamento.


INTRODUCTION: Nasal fractures are common injuries, frequently considered to be minor. Nevertheless, they may cause significant damage, from both a functional and aesthetic perspective. METHODS: Medical records of 144 patients admitted for nasal fracture treatment between February 2002 and October 2008 to the Plastic Surgery Area of the Unicamp Clinical Hospital were analyzed. RESULTS: Patients were predominantly male (75.7 percent), with a male to female ratio of 3.1:1. The most number of cases was observed in 21 to 30 year olds, and the majority of fractures (31.8 percent) were caused by physical aggression. Closed reductions were performed on all patients under local and topical anesthesia after an average of 8 days. Among the studied patients, 31 experienced residual deformity. CONCLUSIONS: Patients typically affected by nasal fractures are young male adults. Closed reduction surgical treatment yields acceptable results, with correct injury evaluation and treatment timing.

ABSTRACT

O tratamento de lesões traumáticas da órbita permanece um desáfio para o cirurgião maxilofacial. Quando a correção cirúrgica não é realizada ou é feita de maneira inadequada, pode ocorrer enoftalmia, diplopia, distopia ocular, restrição da movimentação ocular e disfunção do nervo infraorbital. A importância da cirurgia consiste em liberar o tecido orbitário herniado pelo foco de fratura, restaurar a arquitetura normal da órbita, objetivando um resultado estético e funcional adequado. Nas últimas décadas, vários avanços ocorreram no tratamento cirúrgico destas fraturas, bem como nos métodos diagnósticos. Com o desenvolvimento de tomografias computadorizadas de múltiplos detectores, tornou-se possível a análise tridimensional da órbita, assim como sua avaliação volumétrica, o que revolucionou o manejo cirúrgico destas fraturas. Outro fator com impacto direto nas reconstruções das órbitas é a disponibilidade de diversos biomateriais, para restauração das paredes orbitárias. Assim,o objetivo desse artigo é revisar os materiais disponíveis para reconstrução nos casos de fraturas do assoalho da órbita, comparar suas aplicabilidades práticas e destacar aqueles mais utilizados no Serviço de Cirurgia Plástica do Hospital de Clínicas da Unicamp, nos últimos anos. Dentre os materiais de escolha, em nosso Serviço, destacamos o osso autógeno de calota craniana, a cartilagem de concha auricular, a tela de titânio e o polietileno poroso de alta densidade. Cada biomaterial apresenta indicações específicas, de acordo com as características da fratura orbitária, sendo considerados, para a escolha do material, os resultados a longo prazo e a experiência do cirurgião.


The treatment of traumatic lesions of the orbit remains a challenge for the maxillofacial surgeon. When surgical correction is not performed or is performed incorrectly, may occur enophthalmos, diplopia, ocular dystopia, restriction of ocular movements and dysfunction of the infraorbital nerve. The importance of surgery is to release the herniated orbital tissue at the fracture site, restoring the normal architecture of the orbit, aiming at an adequate functional and aesthetic results. In recent decades, many advances have occurred in the surgical treatment of these fractures, as well as in diagnostic methods. With the development of multislice CT, it became possible to analyze three-dimensional orbit, as well as its volumetric evaluation, which revolutionized the surgical management of these fractures. Another factor with direct impact on the reconstruction of the orbits, is the availability of various biomaterials for the restoration of the orbital walls. The objective of this paper is to review the materials available for reconstruction in cases of fractures of the orbital floor, its applicability to compare practices and highlight those most used in the Plastic Surgery Service, Hospital de Clinicas, Unicamp, in recent years. Among the materials of choice in our service, we highlight the autogenous skull bone, cartilage of ear shell, the titanium mesh and porous high density polyethylene. Each biomaterial has specific indications, according to the characteristics of orbital fracture, being considered for choosing the material, the long-term results and experience of surgeon.
