RESUMEN
Introdução: Este estudo tem o objetivo de avaliar o efeito da compressão intermitente imediata sobre anastomoses arteriais microcirúrgicas em comparação com compressão fixa e com utilização isolada de irrigação com soro fisiológico e heparina em laboratório experimental. Método: 12 ratos Wistar foram aleatoriamente divididos em três grupos para terem suas artérias femorais seccionas e anastomosadas de forma término-terminal, para comparação de patência com 30 minutos e 7 dias. Grupo I: foi realizada compressão intermitente imediata sobre a anastomose por 60 segundos; grupo II: uma compressão fixa foi mantida imediatamente após a anastomose, também por 60 segundos; grupo III, após o término da anastomose, não foi feita nenhuma intervenção adicional. Além da avaliação da patência, os animais foram pesados e medidos os diâmetros arteriais operados. Resultados: 24 artérias femorais foram abordadas. As médias de peso inicial dos ratos dos grupos I, II e III foram, respectivamente, de 243,8g, 254,6g e 260,4g, enquanto as finais foram de 264,4g, 281g e 282,1g (p<0,001). O diâmetro médio das artérias abordadas foi, respectivamente, de 0,89mm, 0,88mm e 0,90mm, e os tempos de anastomoses em minutos, de 25,6, 24,5 e 24,5, respectivamente; As patências finais após 7 dias foram, respectivamente, de 62,5% (p=0,07), 25% (p=0,48) e 50% (p=0,13). Conclusão: A compressão intermitente imediata pode ser realizada ao término de anastomoses arteriais microcirúrgicos sem prejuízo na patência final do procedimento.
Introduction: This study aims to evaluate the effect of immediate intermittent compression on microsurgical arterial anastomoses in comparison with fixed compression and only observation in an experimental laboratory. Methods: The two femoral arteries of twelve male Wistar rats were sectioned and reanastomosed to compare patency at 30 minutes and 7 days. Group I: immediate intermittent compression was performed over the anastomosis for 60 s; group II: a fixed compression was maintained immediately after the anastomosis for 60 s; group III: after completion of the anastomosis, no additional intervention was performed. In addition to the patency assessment, the animals were weighed and the operated arterial diameters were measured. Results: Twenty-four femoral arteries were examined. Initial average weights of the rats in groups I, II, and III were 243.8g, 254.6g, and 260.4g, respectively, while the final weights were 264.4g, 281g, and 282.1g (p<0.001), respectively; mean diameter of the approached arteries was 0.89, 0.88, and 0.90mm, respectively, and the anastomoses (time in minutes) were 25.6, 24.5, and 24.5, respectively; final patencies after 7 days were 62.5% (p=0.07), 25% (p=0.48), and 50% (p=0.13), respectively. Conclusion: Immediate intermittent compression can be performed at the end of microsurgical arterial anastomoses without affecting the final patency of the procedure.
RESUMEN
PURPOSE: To evaluate the use of the latest generation smartphone camera in performing arterial microanastomosis in rats. METHODS: Ten Wistar rats were divided into 2 groups and underwent anastomosis of the right carotid artery with the aid of magnification from a microscope (group M) and a smartphone camera (group S), to compare patency in 72 hours, as well as to measure the weight of the animals, diameter of the carotid arteries and anastomosis time. RESULTS: There was no statistical difference between the weight of the animals or the diameter of the carotid arteries. There was a statistical difference for the time spent on anastomoses, which was greater in group S, with higher rates of thrombosis (p < 0.05). CONCLUSIONS: Although our patency and anastomosis time results were statistically lower in the smartphone group, there was success in some cases. As the segment continues to progress, it is likely that the results will improve in line with the evolution of camera technology.

RESUMEN
Introdução: A abdominoplastia está entre os procedimentos estéticos mais procurados na cirurgia plástica nos últimos anos. Dentro da perspectiva da imagem corporal, a confecção do neoumbigo é peça chave, e sua ausência, distorção ou má cicatrização comprometem o resultado cirúrgico. Diversas técnicas foram descritas, mas todas com suas limitações. O objetivo foi reunir um resumo das possibilidades cirúrgicas apresentadas na Revista Brasileira de Cirurgia Plástica (RBCP), além de reapresentar a técnica em H. Método: Foi realizada revisão qualitativa da literatura publicada na RBCP no período de 2000 a 2021. Foram incluídos artigos que descrevessem uma proposta de umbilicoplastia, referindo número de pacientes, idade, tempo de seguimento, avaliação da satisfação dos pacientes e complicações; sendo excluídas publicações sem fins estéticos ou pacientes pós grandes perdas ponderais. Resultados: Foram encontrados 38 artigos, sendo excluídos 7 pela análise dos títulos e resumos. Os demais artigos foram revisados por dois autores independentes, sendo realizada a exclusão de mais 20 artigos. No final, 11 artigos foram incluídos nesta revisão. Conclusão: A onfaloplastia em abdominoplastias pode ser realizada de várias formas, possibilitando uma gama variável de alternativas para os cirurgiões. A técnica em H é mais uma dessas ferramentas, podendo ser amplamente utilizada e trazendo resultados consistentes.
Introduction: Abdominoplasty has been among the most popular cosmetic procedures in plastic surgery in recent years. From the perspective of body image, making the new navel is a key part, and its absence, distortion, or poor healing compromises the surgical result. Several techniques have been described, but all with their limitations. The objective was to gather a summary of the surgical possibilities presented in the na Revista Brasileira de Cirurgia Plástica (RBCP), in addition to reintroducing the technique in H. Method: A qualitative review of the literature published in the RBCP in the period from 2000 to 2021 was carried out. Articles were included that described a proposal for umbilicoplasty, referring to the number of patients, age, follow-up time, assessment of patient satisfaction, and complications, excluding publications without aesthetic purposes or patients after major weight loss. Results: 38 articles were found, 7 of which were excluded by analyzing the titles and abstracts. Two independent authors reviewed the other articles, excluding another 20. In the end, 11 articles were included in this review. Conclusion: Omphaloplasty in abdominoplasties can be performed in several ways, providing surgeons with various alternatives. The H technique is one of these tools which can be widely used and bring consistent results.
RESUMEN
Introduction: Keloids are one of the most aggressive spectrums of healing disorders. They have a unique pathophysiology and multiple specific genetic and cellular factors, which have not yet been fully elucidated. So far, literature reviews have found the influence of genetics, injury site, and ethnicity on the incidence and rate of recurrence. Furthermore, the need to associate an adjuvant method with surgical excision has already been verified, but the best therapy has yet to be defined. Method: A retrospective analysis of medical records was carried out to assess the profile of patients who underwent postoperative radiotherapy with an electron beam to treat keloids at the Hospital das Clínicas da Faculdade de Medicina de Botucatu between 2015 and 2019. Results: Data from 131 patients were evaluated, with 269 keloid scars treated. The average duration of treatment was 51 days, and the number of sessions was 17. White patients were predominant (78%) and women (70%), with surgical incision being the main cause of formation (49%) and ear the most identified location (33%). Women were more likely to complete the proposed treatment (p=0.04), while non-literates completed less than those who had at least completed primary or secondary education (p<0.0001). Conclusion: Postoperative radiotherapy for keloid scars is a well-established treatment in the literature and an important tool for plastic surgeons. Knowing the profile of patients who need this therapy is essential to create methods that improve adherence and results.
Introdução: Os queloides correspondem a um dos espectros mais agressivos dos distúrbios da cicatrização. Possuem fisiopatologia ímpar e múltiplos fatores genéticos e celulares específicos, ainda não totalmente elucidados. Até o momento, revisões literárias encontraram influência da genética, local da lesão e etnia sobre a incidência e taxa de recorrência. Ademais, já foi constatada a necessidade de associação de um método adjuvante com a excisão cirúrgica, mas ainda sem definição da melhor terapia. Método: Realizada uma análise retrospectiva de prontuários para avaliação do perfil dos pacientes submetidos a radioterapia pós-operatória com feixe de elétrons para o tratamento de queloides no Hospital das Clínicas da Faculdade de Medicina de Botucatu, entre 2015 e 2019. Resultados: Foram avaliados os dados de 131 pacientes, com um total de 269 cicatrizes queloideanas tratadas. A média da duração do tratamento foi de 51 dias e do número de sessões, de 17. Houve predominância de pacientes brancos (78%) e de mulheres (70%), sendo incisão cirúrgica a principal causa de formação (49%) e a orelha a localização mais identificada (33%). As mulheres tiveram mais chance de completar o tratamento proposto (p=0,04), enquanto os não alfabetizados completaram menos do que aqueles que tinham pelo menos ensino fundamental ou médio completo (p<0,0001). Conclusão: A radioterapia pós-operatória em cicatrizes queloideanas é um tratamento consagrado na literatura e uma importante ferramenta do cirurgião plástico. Conhecer o perfil dos pacientes que necessitam desta terapia é fundamental para criar métodos que melhorem a adesão e o resultado da mesma.
RESUMEN
Moebius syndrome is a rare congenital facial palsy that can generate serious emotional repercussions, mainly due to the inability to smile. Currently, no treatment is available; however, surgery can restore muscle function. This case report introduces a new technique for the treatment of Moebius syndrome with zygomatic muscle neurotization using nerve grafts and end-to-side neurorrhaphies, in a 3-year-old girl diagnosed with bilateral Moebius syndrome who was unable to smile on the left side. After 4 years, the patient presented with full smile restoration on the left side, with right and left independent movements and complete symmetry.
RESUMEN
As cicatrizes queloidianas afetam diversas populações, comprometendo a qualidade de vida dos pacientes. Vários tratamentos são apresentados na literatura. O presente estudo visou a realização de uma revisão integrativa dos artigos de revisões sistemáticas e/ou metanálises que abordam o seu tratamento nas bases de dados PubMed, LILACS, MEDLINE e Cochrane no período de 2015 a 2021. Após a identificação, e seguindo os critérios de seleção e elegibilidade, foram incluídos 24 artigos para revisão qualitativa. Observamos que as diferentes modalidades de tratamento empregadas para os queloides são afetadas pela dificuldade de avaliar recorrência, ainda mantendo muitas taxas de insucesso e necessidade de novos estudos.
Keloid scars affect different populations, compromising patients' quality of life. The literature presents several treatments. The study aimed to conduct an integrative review of systematic review articles and/or meta-analyses addressing keloid treatment in the PubMed, LILACS, MEDLINE, and Cochrane databases from 2015 to 2021. After identification and following the selection and eligibility criteria, 24 articles were included for qualitative review. We observed that the difficulty in evaluating recurrence affected different keloids treatment modalities, still presenting many failure rates and the need for further studies.
