RESUMO

Pectoralis major muscle flaps are considered versatile and allow large reconstructions of anatomical defects within a single surgical procedure. Considered a "workhorse" due to these characteristics, the pectoralis major muscle is an excellent option for surgical reconstruction. Several uses of this flap are described in the literature, such as protection of the jugulocarotid system after cervical lymph node dissection, oral, cervical, breast, diaphragmatic, hypopharyngeal, pharyngeal, laryngeal, and esophageal reconstructions.

RESUMO

INTRODUCTION AND IMPORTANCE: Ewing sarcoma is a primary malignant tumor of bone and, to a lesser extent, soft tissues. Within oncological management, surgery with extensive local control and reconstruction is the most accepted option, however, the size, extension of the tumor, the age of the patient and distant involvement can make this option difficult. CASE PRESENTATION: We present a clinical case of a 3-year-old infant with Ewing sarcoma in the proximal femur, who was managed with wide resection of the tumor plus proximal humerus allograft, which acted as a proximal femur for 2 years and then presented joint failure due to what was done was the application of a cemented stem over the remnant of the allograft to save the hip. CLINICAL DISCUSSION: In the presented case, similar to the report by Zoccali a malignant tumor in the proximal femur of a pediatric patient is documented. In these cases, where the distal femoral growth plate is disease-free, a reconstruction technique preserving the growth plate is proposed. CONCLUSION: The technique of proximal femoral allograft with a proximal humeral graft is an acceptable reconstructive treatment alternative for young patients with Ewing sarcoma, especially when conventional treatment options are limited. This approach helps avoid limb-threatening surgeries such as amputation or rotationplasty, providing a viable and functional solution for limb salvage in these cases.

RESUMO

Introducción: La herida es una pérdida de continuidad de la piel o mucosa producida por algún agente físico o químico. Una herida es "compleja" cuando por su extensión, localización, profundidad o exposición de elementos nobles, necesita para su curación una terapéutica especial. Este es el caso de heridas con compromiso tisular que afecta a estructuras como músculos, fascias, tendones, huesos, vasos sanguíneos, nervios o las lesiones de lenta evolución como úlceras o escaras. Objetivos: Determinar el método de reconstrucción más utilizado en el manejo terapéutico de las heridas complejas del tercio distal de la pierna en los pacientes atendidos en el Hospital de Trauma y en la Unidad de Cirugía Plástica de la FCM - UNA. Materiales y métodos: Estudio de diseño observacional, tipo de estudio descriptivo y retrospectivo. Fueron incluidos pacientes de ambos sexos, mayores de edad, con heridas complejas en el tercio distal de la pierna, atendidos en el Hospital de Trauma y en la Unidad de Cirugía Plástica de la FCM - UNA, durante el periodo 2010 al 2019. Resultados: Se incluyó a 112 pacientes de los cuales el 80,36 % fue hombres y el 19,64 % mujeres. Las edades estaban comprendidas entre los 18 y los 73 años y una media de 33,8 ± 14 años. La edad más frecuente fue 18 años. La mediana de edad es de 30 años, lo que implica que la mitad de la muestra tuvo por lo menos dicha edad. En cuanto a la procedencia, el 41,07 % era del interior, el 30,36 % del departamento Central y el 28,57 % restante de Asunción. En cuanto al mecanismo de la lesión, se puede observar que el mecanismo más frecuente fue el accidente de tráfico, seguido por caída de altura, en un gran porcentaje. En cuanto a la evolución y complicaciones se puede ver que 92 individuos, o sea 82 % de los pacientes no tuvo ninguna evolución negativa o complicaciones. Lo más común fue la infección con 1,9% de prevalencia, la pérdida parcial del colgajo o piel representan el 2,4%, dehiscencia de la sutura el 0,9 %, hematoma 0,6 % y pérdida total del colgajo 0,54 %. En cuanto al tratamiento aplicado, se debe tener en cuenta que los pacientes pudieron haber recibido más de un tratamiento por lo que el tamaño de la muestra se refiere a las visitas. El tratamiento más frecuente fue el colgajo sural con 28,57%, tutor externo con el 20,19%, injerto de piel 16,46%, toillete 12,73% y colgajo fascio - cutáneo en 6,21%. Conclusión: La gran mayoría de los casos tratados corresponde a algún tipo de accidente de tránsito. Se necesita de un equipo multidisciplinario: ortopedistas, cirujanos plásticos, cirujanos vasculares, fisioterapeutas, etc. en trabajo coordinado para tratar estas graves lesiones de forma a obtener resultados favorables. Para la cobertura de la pierna traumatizada, con exposición ósea, recurrimos a los colgajos musculares, en el 1/3 proximal el gemelo, en el 1/3 medio el sóleo. Para la cobertura del 1/3 distal de la pierna utilizamos el colgajo neuro-veno-fascio-cutáneo (sural) a pedículo distal.

Introduction: The wound is a loss of continuity of the skin or mucosa produced by some physical or chemical agent. A wound is "complex" when due to its extension, location, depth, exposure of noble elements, it requires special therapy to heal. This is the case of wounds with tissue involvement that affects structures such as muscles, fascia, tendons, bones, blood vessels, nerves, or slowly evolving lesions such as ulcers or bedsores. Objectives: Determine the reconstruction method most used in the therapeutic management of complex wounds of the distal third of the leg in patients treated at the Trauma Hospital and the Plastic Surgery Unit of the FCM - UNA. Materials and methods: Observational, descriptive, and temporally retrospective study. Patients of both sexes, of legal age, with complex wounds in the distal third of the leg, treated at the Trauma Hospital and in the Plastic Surgery Unit of the FCM - UNA, during the period 2010 to 2019, were included. Results: 112 patients were included, of which 80.36% are men and 19.64% are women. The ages range from 18 to 73 years and an average of 33.8 ± 14 years. The most common age was 18 years. The median age is 30 years, which implies that half of the sample is at least that age. Regarding origin, 41.07% are from the interior, 30.36% from the Central department and the remaining 28.57% from Asunción. Regarding the mechanism of injury, the most frequent mechanism was a traffic accident, followed by a fall from a height, in a large percentage. Regarding the evolution and complications, 92, that is, 82% of the patients do not have any negative evolution or complications. The most common was infection with 1.9%, partial loss of the flap or skin represented 2.4%, suture dehiscence with 0.9%, hematoma 0.6%, and total loss of the flap 0.54. %. Regarding the treatment applied, it must be considered that patients may have received more than one treatment, so the sample size refers to visits. The most frequent treatment was the sural flap with 28.57%, external tutor with 20.19%, skin graft 16.46%, toilette 12.73% and fasciocutaneous flap in 6.21%. Conclusion: Most cases treated correspond to some type of traffic accident. A multidisciplinary team is needed: orthopedists, plastic surgeons, vascular surgeons, physiotherapists, etc. in coordinated work to treat these serious injuries to obtain favorable results. To cover the traumatized leg, with bone exposure, we resort to muscle flaps. In the proximal 1/3, the gastrocnemius. In the middle 1/3, the soleus. To cover the distal 1/3 of the leg we used the neuro-veno-fascio-cutaneous (sural) flap to the distal pedicle.

RESUMO

Si bien el conocimiento científico para el tratamiento de la periimplantitis ha avanzado significativamente en los últimos años, sigue en discusión qué tipo de abordaje quirúrgico genera los mejores resultados clínicos y si el uso de biomateriales da mejoras significativas en dicho tratamiento. Este reporte de caso describe un abordaje quirúrgico reconstructivo de un defecto intraóseo por periimplantitis en una paciente que refería dolor y un intenso sangrado en sus implantes dentales, empleando un sustituto óseo anorgánico mineral bovino, sin el uso de una membrana o barrera, y con un protocolo de descontaminación de la superficie del implante mecánico y químico. Posteriormente, a las 20 semanas de realizado el procedimiento, se hizo la evaluación del defecto, obteniendo profundidades al sondeo menores a 5 mm, ausencia de sangrado al sondeo en todos los sitios y un llenado óseo radiográfico de aproximadamente 90%; cumpliendo con los criterios de éxito de la terapia periimplantaria. Lo anterior muestra que la terapia reconstructiva para los defectos por periimplantitis puede ser posible mediante el uso de un sustituto óseo xenogénico únicamente y con una correcta descontaminación de la superficie del implante (AU)

Although scientific knowledge for the treatment of peri-implantitis have advanced significantly in recent years, the type of surgical approach that generates the best clinical results is still under discussion and whether the use of biomaterials gives significant improvements in said treatment. This case report describes a reconstructive surgical approach for a periimplantitis intrabony defect using an anorganic bovine bone substitute, without the use of a membrane or barrier, and with a mechanical and chemical implant surface decontamination protocol. Twenty weeks after the procedure, the defect was reassessed, obtaining probing depths of less than 5 mm, no bleeding on probing in all sites, and radiographic bone filling of approximately 90%; meeting the success criteria for the peri-implant therapy. This shows that reconstructive therapy for periimplantitis defects may be possible using a xenogeneic bone substitute only and proper decontamination of the implant surface (AU)

RESUMO

This case report aims to delineate the challenges and management strategies for a patient with bilateral mutilated hands within a secondary care level in Mexico, contributing to medical literature and potentially guiding future patient care. Mutilated hands represent a significant surgical and rehabilitative challenge due to the profound structural damage they cause, leading to considerable functional impairment and psychological distress. The complexity of these injuries necessitates a multidisciplinary approach, particularly in resource-constrained settings. We present a case of a 45-year-old male with no prior significant medical history who sustained bilateral mutilated hands from an industrial accident involving hot rollers. The patient underwent extensive surgical reconstruction and postoperative care, facing complications such as skin graft integration issues and infections, which required a multidisciplinary treatment approach.

RESUMO

Background: This study aimed to explore a low-cost solution for virtual surgical planning/3D printed surgical guides in a training hospital, assessing the impact on intraoperative time and bleeding. Material and Methods: We included a total of 13 patients. 8 who underwent maxillofacial reconstruction surgery with fibula-free flap utilizing virtual surgical planning/3D printed guides (VP/SG), and 5 using conventional surgery (CS) from 2017 to 2020. The surgical time, bleeding, length of hospital stay, and comorbidities were collected and compared in two groups. We recorded the average cost for the complete surgical planning and 3D printed guides. We applied a qualitative survey to the surgeons involved in the surgical procedures. Results The mean surgical time in the VP/SG group was 8.16 ± 2.7, compared to the CS group 12.5 ± 3.8, showing a 4.34 hours difference with statistical significance (p = 0.033). Patients from the CS group had a higher bleeding volume of 921 ± 467.6 mL VS 760 ± 633.8 mL in the VP/SG group. The average cost for the complete surgical planning and 3D printed guides was 914.44 ± 46.39 USD. All the surgeons who answered the survey preferred to perform the procedure utilizing the virtual planning/3D printed guides. Conclusions Virtual planning and 3D printed surgical guides have the potential to reduce operation time in maxillofacial reconstruction.

RESUMO

Introdução: O trauma de mão constitui uma epidemia, ocorrendo por diversos fatores, como acidentes de trabalho e violência urbana. Isso gera um impacto significativo por ser uma unidade anatômica vulnerável e importante na realização de atividades cotidianas e para o trabalho. Desse modo, faz-se necessária uma avaliação epidemiológica mais aprofundada no que tange, sobretudo, às fraturas de mãos, entendendo sua elevada morbidade. Método: Estudo descritivo e retrospectivo, feito por análise de prontuários de pacientes conduzidos em um hospital terciário no período de janeiro de 2018 a dezembro de 2020. Resultados: Participaram do estudo 290 pacientes, sendo 85,7% do sexo masculino e 14,3% do sexo feminino. 138 indivíduos tinham entre 20 e 39 anos, representando um total de 47,6%. 51,6% eram do interior do estado do Ceará e 48,4% eram da capital. O principal mecanismo de trauma associado às fraturas foram os acidentes de trânsito (36,4%), seguidos por acidentes de trabalho (26,9%) e ferimentos por arma de fogo (14%). Em relação aos ossos fraturados, houve uma acentuada prevalência do acometimento das falangeanas, em todas as faixas etárias, representando 210 pacientes (72,4%). Conclusão: O presente estudo corrobora com os dados presentes na literatura. Desse modo, é evidenciada a repetição de prevalência de faixa etária, principais mecanismos de trauma envolvidos, bem como ossos acometidos nas fraturas de mão.

Introduction: Hand trauma is an epidemic occurring due to several factors, such as work accidents and urban violence. This significantly impacts it as it is a vulnerable and important anatomical unit for daily activities and work. Therefore, a more in-depth epidemiological assessment is necessary regarding hand fractures and understanding their high morbidity. Method: A descriptive and retrospective study was conducted by analyzing the medical records of patients treated in a tertiary hospital from January 2018 to December 2020. Results: 290 patients participated in the study, 85.7% male and 14.3 % female. One hundred thirty-eight individuals were between 20 and 39 years old, representing 47.6%. 51.6% were from the interior of the state of Ceará, and 48.4% were from the capital. The main trauma mechanism associated with fractures was traffic accidents (36.4%), followed by work accidents (26.9%) and firearm injuries (14%). Concerning fractured bones, there was a marked prevalence of phalangeal involvement in all age groups, representing 210 patients (72.4%). Conclusion: The present study corroborates the data present in the literature. In this way, the repetition of the prevalence of age group, main trauma mechanisms involved, as well as bones affected by hand fractures is evidenced.

RESUMO

Introdução: Cicatrizes visíveis podem acarretar agravos, sejam estéticos, psicológicos, funcionais ou sociais, principalmente de grande extensão e volume, como os queloides. A descoberta de novos tratamentos de queloides não é fácil, visto a presença de alguns entraves metodológicos e éticos, sendo uma área pouco explorada. A toxina botulínica tem sido apresentada como alternativa terapêutica em estudos nacionais e internacionais, sendo necessária uma compilação e destaque dos principais estudos que possam subsidiar a prática clínica. Assim, o objetivo foi apresentar uma revisão de escopo sobre a utilização terapêutica da toxina botulínica para o tratamento de cicatrizes queloides. Método: A revisão foi realizada através da estratégia PICO e utilizando o Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Foi realizada nas bases de dados PubMed/ Medline, Biblioteca Virtual em Saúde e SciELO, considerando estudos do período de 2016 até setembro de 2021. Resultados: Foram encontrados 34 artigos no geral relacionados ao tema. Após filtragem e seleção, a revisão foi construída com apoio de 5 artigos. Os estudos variaram entre coorte, relatos de caso, ensaio clínico randomizado e caso-controle. Foi possível observar como principais resultados a ação a curto prazo da toxina botulínica na redução de queloides, maior efetividade na redução dos sintomas e possibilidades de utilização clínica para diferentes populações e manifestações clínicas. Conclusão: O mecanismo de ação da toxina botulínica pode facilitar o tratamento de queloides e redução de sintomas, sendo necessários estudos mais robustos para definição de protocolos cínicos de gestão de cicatrizes.

Introduction: Visible scars can cause problems, whether aesthetic, psychological, functional, or social, mainly of great extension and volume, such as keloids. The discovery of new treatments for keloids is not easy, given the presence of some methodological and ethical obstacles, and it is an area that is little explored. Botulinum toxin has been presented as a therapeutic alternative in national and international studies, requiring a compilation and highlighting of the main studies that can support clinical practice. Thus, the objective was to present a scoping review on the therapeutic use of botulinum toxin for the treatment of keloid scars. Method: The review was carried out using the PICO strategy and using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. It was carried out in the PubMed/ Medline, Virtual Health Library, and SciELO databases, considering studies from 2016 to September 2021. Results: Overall, 34 articles related to the topic were found. After filtering and selection, the review was constructed with the support of 5 articles. The studies varied between cohorts, case reports, randomized clinical trials, and casecontrol. It was possible to observe as main results of the short-term action of botulinum toxin in reducing keloids, greater effectiveness in reducing symptoms, and possibilities of clinical use for different populations and clinical manifestations. Conclusion: The mechanism of action of botulinum toxin can facilitate the treatment of keloids and reduce symptoms, requiring more robust studies to define effective scar management protocols.

RESUMO

Introduction: The umbilicus is a unique physiologic scar of human body. Its absence leads to an unnatural abdominal appearance and can cause psychological and social complexes. Objective: To present a case of neoumbilicoplasty with vertical island pedicle flap for a large pigmented umbilical nevus. Clinical case: A healthy 50-year-old female patient with a history of a pigmentated nevus on the umbilicus since childhood that complains of changes in size and color of it. She also referred notice a lump in the upper umbilical region which was an umbilical hernia. The patient underwent an omphalectomy with oncological margins, an umbilical hernia repair and a neoumbilicoplasty with vertical island pedicle flap. Seroma was the only postoperative complication. Aesthetic results were acceptable and satisfied the patient. Conclusions: This is a rare case not only because the umbilical skin lesions are uncommon but the neoumbilicoplasty technique is rarely used(AU)

RESUMO

BACKGROUND: The injection of illicit, non-regulated foreign materials may trigger an autoimmune autoinflammatory syndrome induced by adjuvants (ASIA). METHODS: A retrospective review of health records was performed to identify patients' epidemiological and clinical characteristics. The issues analyzed were age and gender of cases, occupation, the person who administered the substance, anatomical site, type and volume of the injected substance, time from injection to the onset of symptoms, chief complaint, measures taken to alleviate symptoms, local complications, systemic manifestations, and imaging method to aid in diagnosis. RESULTS: More than 70% of patients were female and dedicated to household activities; the mean age was 44 years for females and 40.7 years for males. One-quarter of patients reported some comorbidity. The most commonly reported substance was mineral oil, whereas the most frequent anatomical site was the gluteal region with volumes around one liter. Signs and symptoms occurred almost exclusively at a local level, pain (40%) and swelling (18%) being the predominant manifestations with a peak incidence after three years. Treatment was mainly medical; surgery, primarily en bloc resection, was performed in 20% of patients. CONCLUSIONS: A myriad of substances may induce autoimmune autoinflammatory syndrome induced by adjuvants (ASIA) when injected for cosmetic purposes. Since effective treatments are scarce, public policies should be enforced to alert the community and limit the consequences of this healthcare problem. LEVEL OF EVIDENCE V: This journal requires that authors assign a level of evidence to each article.

RESUMO

Introdução: A reconstrução da região plantar ainda é um dos grandes desafios da cirurgia plástica reconstrutiva. Os tecidos dessa região apresentam características únicas e que são essenciais para a manutenção da funcionalidade do membro. De toda a região plantar, a região do calcanhar é a área de maior sustentação do peso e submetida ao maior impacto. O retalho fasciocutâneo plantar medial é uma das opções reconstrutivas, pois representa tecido semelhante e mantém a sensibilidade para a área receptora. Método: Foi realizado um estudo retrospectivo através da coleta de dados de prontuário de pacientes que realizaram reconstruções da região do calcanhar com retalho plantar medial, no período de julho de 2013 a setembro de 2019. O estudo foi aprovado pelo Comitê de Ética para Análise de Projetos de Pesquisa do HCFMUSP (Número CAAE: 56849422.0.0000.0068). Resultados: A reconstrução de calcanhar após ressecção de melanoma lentiginoso acral foi realizada em 7 pacientes. Complicações cirúrgicas foram observadas em 3 pacientes, sendo que todos eles tinham idade acima de 50 anos e/ou alguma comorbidade associada. Houve 57,1% de complicações, sendo 37,5% relacionadas ao retalho e 12,5% relacionadas à área doadora. Ocorreram 3 necroses totais de retalho (42,9%) e 1 perda total de enxerto na área doadora (14,3%). Conclusão: O retalho plantar medial se apresenta como uma boa alternativa para a realização de reconstruções oncológicas de defeitos na região plantar do pé. Contudo, deve-se ponderar a escolha do paciente ideal e lembrar que a dissecção do seu pedículo vascular não é de fácil execução.

Introduction: Resurfacing the sole is still one of the great challenges of reconstructive plastic surgery. The tissues on the sole of the foot have unique characteristics essential for maintaining the limbs functionality. The heel has the most significant weight support and is subjected to the entire soles greatest impact. The medial plantar artery flap is one of the reconstructive options, as it represents similar tissue and maintains sensitivity to the recipient area. Methods: A retrospective study was performed by collecting data from medical records of patients who underwent reconstructions of the heel with a medial plantar artery flap from July 2013 to September 2019. The study was approved by the Ethics Committee for Analysis of Research Projects of HCFMUSP (CAAE number: 56849422.0.0000.0068). Results: Heel reconstruction was performed in 7 patients after acral lentiginous melanoma excision. Surgical complications were observed in 3 patients, all of whom were aged over 50 years or have associated comorbidity. There were 57.1% of complications, 37.5% related to the flap, and 12.5% related to the donor area. There were three total flap necroses (42.9%) and one total graft loss in the donor area (14.3%). Conclusion: The medial plantar flap presents itself as a good alternative for performing oncological reconstructions of defects in the plantar region of the foot. However, the choice of the ideal patient should be considered and we must remember that the dissection of its vascular pedicle is not easily executed.

RESUMO

Introdução: No Brasil, queimaduras acometem cerca de um milhão de pessoas/ano, a maioria do sexo masculino. Além de prejuízos físicos e emocionais, há impacto econômico, com gastos para o sistema de saúde, indenizações e incapacidades laborais. Por estas razões, estudos epidemiológicos são importantes para traçar o perfil da população mais acometida, orientando a prevenção dessa afecção. Método: Revisão dos prontuários de 398 vítimas de queimaduras, internados na Santa Casa de Santos, de janeiro de 2016 até dezembro de 2019. Resultados: Os principais acometidos são homens, jovens, em ambiente doméstico, por líquidos aquecidos, causando em sua maioria queimaduras de segundo grau, atendidos em até 24 horas, considerados grandes queimados e internados em enfermaria por até duas semanas. Aproximadamente 90% recebeu alta com melhora, necessitando apenas de desbridamento e curativos. Conclusão: Nosso trabalho concorda com maioria das revisões em relação à prevalência do sexo masculino, jovens, economicamente ativos, em suas residências, com líquidos aquecidos, acidentalmente. Outros estudos apontaram crianças como as mais afetadas, mostrando necessidade de políticas voltadas a ambas as faixas etárias. Com relação à internação, a maioria permaneceu em enfermaria, com queimaduras de segundo grau, prevalecendo os grandes queimados, o que acarreta maior gravidade e custos. Esse dado vai contra alguns trabalhos, que apontam queimadura de segundo grau como principal, porém com menos de 10% da superfície corporal queimada. A maior parte dos pacientes, tanto neste quanto na maioria dos estudos, apresentou bom desfecho, sem necessidade de Unidade de Terapia Intensiva ou procedimentos cirúrgicos, mostrando a importância do desbridamento precoce e cuidados com curativos.

Introduction: In Brazil, burns affect around one million people/year, the majority of whom are male. In addition to physical and emotional losses, there is an economic impact, with costs for the health system, compensation, and work disabilities. For these reasons, epidemiological studies are important to outline the profile of the most affected population, guiding the prevention of this condition. Method: Review the medical records of 398 burn victims admitted to Santa Casa de Santos from January 2016 to December 2019. Results: The main victims were young men in a domestic environment, by heated liquids, mostly causing second degree burns, treated within 24 hours, considered major burns, and admitted to the infirmary for up to two weeks. Approximately 90% were discharged with improvement, requiring only debridement and dressings. Conclusion: Our work agrees with most reviews regarding the prevalence of young, economically active males with accidentally heated liquids in their homes. Other studies highlighted children as the most affected, showing the need for policies for both age groups. Regarding hospitalization, the majority remained in the ward, with second-degree burns, with major burns prevailing, which leads to greater severity and costs. This data goes against some studies, which indicate second-degree burns as the main burn, with less than 10% of the body surface burned. In both this and most studies, most patients had a good outcome, without needing an Intensive Care Unit or surgical procedures, showing the importance of early debridement and care with dressings.

RESUMO

Introdução: O carcinoma de células escamosas é o tumor maligno mais frequente dos lábios e acomete principalmente o lábio inferior. O tratamento adequado desta neoplasia deve ser precoce e radical, pois metástases podem ocorrer. Considerando que os lábios têm extrema relevância na dinâmica e motricidade da face, a reconstrução labial após grandes ressecções nesta região é um desafio para o cirurgião na busca de bons resultados estéticos e funcionais. Este estudo busca apresentar uma técnica já consagrada e confiável para a reconstrução do lábio inferior após ressecções tumorais, o retalho de Karapandizic. Método: Nesta revisão de casos são avaliados, retrospectivamente, 4 pacientes que tiveram o lábio inferior reconstruído por meio da técnica de Karapandzic no período de 2013-2022. Resultados: As complicações mais frequentemente observadas foram cicatriz hipertrófica, deiscência de sutura em vermelhão de lábio e microstomia (redução da abertura oral). A redução da fenda labial (microstomia) foi corrigida parcialmente através do uso de órteses odontológicas, não havendo necessidade de indicação de comissuroplastia em nenhum dos casos. Outra colaboração deste trabalho refere-se à utilização do ecoDoppler colorido pré-operatório, que permite o planejamento do retalho verificando a viabilidade do pedículo vascular e o real posicionamento deste pedículo, reduzindo as chances de lesão inadvertida dos vasos durante a cirurgia. Conclusão: Mesmo sendo a microstomia uma limitação deste retalho, concluímos que esta técnica atende à necessidade de reconstrução de lábio inferior em grandes ressecções, uma vez que é capaz de proporcionar resultados satisfatórios em termos oncológicos, funcionais e estéticos.

Introduction: Squamous cell carcinoma is the most common malignant tumor of the lips and mainly affects the lower lip. Adequate treatment of this neoplasm must be early and radical, as metastases can occur. Considering that the lips are extremely important in the dynamics and motricity of the face, lip reconstruction after major resections in this region is a challenge for the surgeon in the search for good aesthetic and functional results. This study seeks to present an already established and reliable technique for reconstructing the lower lip after tumor resection, the Karapandizic flap. Method: In this case review, 4 patients with lower lips reconstructed using the Karapandzic technique in 2013-2022 are retrospectively evaluated. Results: The most frequently observed complications were hypertrophic scar, lip vermilion suture dehiscence, and microstomia (reduction of oral opening). The cleft lip (microstomia) reduction was partially corrected through dental orthoses, with no need for commissuroplasty in any of the cases. Another contribution of this work is the use of preoperative color echoDoppler, which allows flap planning by checking the viability of the vascular pedicle and the actual positioning of this pedicle, reducing the chances of inadvertent injury to the vessels during surgery. Conclusion: Even though microstomy is a limitation of this flap, we conclude that this technique meets the need for lower lip reconstruction in large resections, as it can provide satisfactory results in oncological, functional, and aesthetic terms.

RESUMO

Introdução: A mamoplastia de aumento é uma dos procedimentos mais realizados em Cirurgia Plástica em todo o mundo. A mastopexia com prótese também é um procedimento amplamente realizado, reservado para outro perfil de pacientes. Muitas complicações podem ser evitadas quando se estudam os fatores de risco para desfechos desfavoráveis. Método: Trata-se de um estudo retrospectivo realizado por meio da análise de prontuários de pacientes submetidas a mamoplastia primária de aumento e mastopexia com implantes mamários no período de janeiro de 2018 a dezembro de 2020. Resultados: Das 112 pacientes submetidas a mamoplastia com implante mamário no período do estudo, 76 foram submetidas a mamoplastia de aumento primária (67,86%) e 36 pacientes a mastopexia com implante mamário (32,14%). As pacientes submetidas a mastopexia apresentaram maior média de idade em relação àquelas submetidas a mamoplastia de aumento (p<0,001) e apresentaram menores volumes de implantes mamários (p=0,002). As complicações mais comuns em ambos os grupos incluem a deiscência da ferida operatória, mais comum após mastopexia com prótese. Conclusão: A mastopexia de aumento realizada em procedimento único apresenta maior índice de complicações quando comparada à mamoplastia de aumento realizada individualmente. No entanto, o maior número de complicações precoces observadas no procedimento combinado é a soma dos dois procedimentos distintamente individuais e não um aumento exponencial.

Introduction: Breast augmentation is one of the most performed procedures in Plastic Surgery worldwide. Mastopexy with prosthesis is also a widely performed procedure reserved for other patient profiles. Many complications can be avoided when studying risk factors for unfavorable outcomes. Method: This is a retrospective study carried out through the analysis of medical records of patients who underwent primary breast augmentation and mastopexy with breast implants from January 2018 to December 2020. Results: Of the 112 patients who underwent mammoplasty with the implant during the study period, 76 patients underwent primary breast augmentation (67.86%), and 36 underwent mastopexy with breast implant (32.14%). Patients undergoing mastopexy had a higher average age compared to those undergoing breast augmentation (p<0.001) and had smaller volumes of breast implants (p=0.002). The most common complications in both groups include surgical wound dehiscence, more common after mastopexy with prosthesis. Conclusion: Breast augmentation performed as a single procedure has a higher rate of complications when compared to breast augmentation performed individually. However, the greater number of early complications observed with the combined procedure is the sum of the two distinctly individual procedures and not an exponential increase.

RESUMO

Introdução: A reconstrução oncológica de defeitos extensos em cabeça e pescoço impõe ao cirurgião plástico a difícil decisão entre o uso de retalhos livres e retalhos pediculados. O retalho supraclavicular é um dos principais exemplos de retalho pediculado, sendo versátil, com espessura delgada e cor semelhante à região a ser reconstruída. Método: Um estudo retrospectivo foi realizado através da coleta de dados de prontuário de pacientes internados no Instituto do Câncer do Estado de São Paulo, entre dezembro de 2010 e março de 2020. Resultados: Dentre os 62 pacientes reconstruídos com retalho supraclavicular, 37 eram do sexo masculino e 25 do sexo feminino. Cinquenta e oito pacientes (93,5%) possuíam alguma comorbidade associada. Ao todo, 27 complicações relacionadas ao retalho (43,5%) foram registradas, sendo 5 necroses totais (8%). Conclusão: O retalho supraclavicular possui importante papel nas reconstruções oncológicas de cabeça e pescoço e deve ser considerado como opção em pacientes maus candidatos a retalhos microcirúrgicos.

Introduction: The oncological reconstruction of extensive defects in the head and neck requires the plastic surgeon to make a difficult decision between the use of free flaps and pedicled flaps. The supraclavicular flap is one of the main examples of a pedicled flap, being versatile, with a thin thickness and similar color to the region to be reconstructed. Method: A retrospective study was carried out by collecting data from medical records of patients admitted to the Cancer Institute of the State of São Paulo between December 2010 and March 2020. Results: Among the 62 patients reconstructed with a supraclavicular flap, 37 were male and 25 female. Fifty-eight patients (93.5%) had some associated comorbidity. In total, 27 complications related to the flap (43.5%) were recorded, 5 of which were total necrosis (8%). Conclusion: The supraclavicular flap plays an important role in head and neck oncological reconstructions and should be considered as an option in patients who are poor candidates for microsurgical flaps.

Introduction: Fournier's gangrene is currently defined as a specific form of synergistic, rapid, progressive and multibacterial necrotizing fasciitis, which mainly affects the muscular fascia of the perineal, genital, or perianal region and even the abdominal wall; with genitourinary, colorectal, or idiopathic starting point. All of this, accompanied by skin gangrene in these areas due to thrombosis of subcutaneous blood vessels. Objectives: To describe the epidemiological and surgical characteristics of the sequelae patients of Fournier's disease in the Plastic Surgery Unit of the Hospital de Clínicas in a period of 2 years. Materials and methods: Observational, descriptive, cross-sectional, temporally retrospective, case series type study. The type of sampling was non-probabilistic at convenience. Eighteen sequelae patients of Fournier's disease reconstructed in the Plastic Surgery Unit of Hospital de Clínicas between 2020 and 2021 are presented. Results: During the study period, 395 surgeries were performed in the Plastic Surgery Service of the Hospital de Clínicas, of which 18 patients underwent surgery for sequelae of Fournier's disease, which represents 5% of the total. Regarding demographic variables, age ranged between 37 and 85 years with greater impact in the sixth decade of life with an average of 61 years. 94% of the patients were male; 89% of the patients had type 2 diabetes mellitus as an underlying pathology, followed by obesity in 72% and high blood pressure in 56% of cases; In 83% of the cases, the scrotal region was affected, followed by the perineal region in 56% of the patients and the penis in 50% of the cases. The most frequently used reconstructive technique was flaps in 10 patients, followed by skin grafting in 8 patients, and primary closure in 6 patients. It is worth mentioning that in some patients several reconstructive techniques were used following the concept of reconstruction by sub- anatomical units, among the flaps the most used were the medial femoral circumflex perforator flap (gracilis perforator) with 50% of the cases followed by the fasciocutaneous transposition flap of the internal pudendal with 30%, and finally the fasciocutaneous advancement flap with 20% (Table 3). The average hospital stay was 3 days, with a minimum of 1 day and a maximum of 5 days postoperatively. Suture dehiscence was reported as a complication in 3 patients; no complications were observed in 77% of the cases. Conclusion: The sequelae of Fournier's disease undergoing surgeries represent 5% of the total number of surgeries performed in our Service, they are more prevalent in the sixth decade of life, it affects more males with type 2 diabetes mellitus as the underlying pathology, the reconstructive techniques used in the sequelae are variable according to the anatomical regions affected and can range from primary closure to the use of flaps for repair.

RESUMO

The bipedicled Deep Inferior Epigastric Perforator (DIEP) flap, originally described and primarily utilized in autologous breast reconstruction for specific cases, has expanded its applications to encompass diverse anatomical regions in recent years. This report presents the case of a 69-year-old woman with a recurrent giant thyroid tumor who underwent surgical resection, resulting in a large cervico-thoracic defect effectively reconstructed using a bipedicled DIEP flap. The patient's postoperative recovery was uneventful, and the follow-up assessments revealed a healthy, well-perfused flap that provided sufficient coverage to critical structures, adequate restoration of the region contour, and enough volume to offset potential adverse effects of subsequent radiation therapy. In addition, this report incorporates a concise literature review highlighting the expanding indications of the bipedicled DIEP flap beyond breast reconstruction, showing the versatility and efficacy of the bipedicled DIEP flap in addressing complex soft-tissue defects in various anatomical areas.
