Supervivencia de injerto graso en la lipotransferencia glútea / Survival of fat graft in gluteal lipotransfer

Introducción: El aumento de glúteos tiene como objetivo lograr una apariencia y contorno más joven; así como crear la proporción ideal entre cintura y cadera. Esto se puede lograr mediante la lipoinyección, aunque en este caso existen controversias en cuanto a la viabilidad del tejido injertado y la supervivencia de la grasa. Objetivo: Determinar el porcentaje de supervivencia del injerto de grasa autóloga y su relación con el volumen inyectado en pacientes sometidas a lipotransferencia glútea. Métodos: Se realizó un estudio observacional, descriptivo, de corte longitudinal y prospectivo con una muestra de 44 pacientes sometidas a lipotransferencia glútea en el Servicio de Cirugía Plástica del Hospital Docente Clínico Quirúrgico Dr. Miguel Enríquez en el período comprendido entre marzo de 2018 y junio de 2021. Resultados: El estudio evidencia que, mediante ultrasonido y fórmulas, el volumen promedio y la altura de la de grasa en los glúteos se duplica en el posoperatorio mediato y disminuye en el posoperatorio tardío sin llegar a los valores del preoperatorio. Además, se estableció que cerca de la media del volumen de grasa autóloga injertada en los glúteos sobrevive de manera definitiva en el posoperatorio tardío. Además, quedó establecido que la relación entre el volumen infiltrado y la supervivencia del injerto de grasa autóloga es inversamente proporcional: mientras mayor es el volumen, menor es su supervivencia. Conclusiones: Solo la mitad del volumen de grasa autóloga injertada en los glúteos sobrevive de manera definitiva, y la supervivencia de la grasa es inversamente proporcional al volumen infiltrado(AU)

Introduction: Buttock augmentation aims to achieve a more youthful appearance and contour; as well as creating the ideal proportion between waist and hips. This can be achieved by lipoinjection, although in this case there are controversies regarding the viability of the injected tissue and the survival of the fat. Objective: To determine the percentage of autologous fat graft survival and its relationship with the injected volume in patients undergoing gluteal fat transfer. Methods: An observational, descriptive, longitudinal and prospective study was carried out, with a sample of 44 patients undergoing gluteal lipotransfer, in the plastic surgery service of the Dr. Miguel Enriquez Clinical Surgical Teaching Hospital, in the intermediate period between March 2018 to June 2021. Results: The study shows that through ultrasound and formulas, the average volume and height of fat in the buttocks doubles in the immediate postoperative period, decreasing in the late postoperative period, without reaching preoperative values. Furthermore, it's established that about the mean volume of autologous fat grafted to the buttocks survives definitively in the late postoperative period. In addition, it was established that the relationship between the infiltrated volume and the survival of the autologous fat graft is inversely proportional, the greater the volume, the less its survival. Conclusions: Only half of the volume of autologous fat injected into the buttocks survives definitively, and the survival of the fat is inversely proportional to the volume injected(AU)

Reconstrucción mamaria diferida con expansor-implante y matriz dérmica autóloga. Una alternativa terapéutica aplicable en tejidos no irradiados. / Delayed breast reconstruction with expander-implant and autologous dermal matrix. An alternative applicable therapeutic in non irradiated tissues.

INTRODUCCIÓN Y OBJETIVO: la reconstrucción mamaria diferida o post mastectomía tiene una importancia trascendental en la vida de la mujer así también como parte del tratamiento integral y multidisciplinario del cáncer mamario, ya que tamaña agresión impacta en la autoestima y funcionalidad social en aquellas mujeres que por algún motivo no fueron sometidas a reconstrucción inmediata. El objetivo es describir a través de la técnica expansor-implante, matriz dérmica autóloga, injerto de grasa y reconstrucción del complejo areola pezón con tejidos autólogos, los resultados alcanzados en pacientes mastectomizadas y reconstruidas de manera diferida. MATERIAL Y MÉTODO: es un estudio retrospectivo, longitudinal, observacional y descriptivo de una serie pequeña de 5 pacientes privadas mastectomizadas no irradiadas que no fueron sometidas por algún motivo a reconstrucción inmediata en otros centros médicos y que acudieron al consultorio privado derivadas por médicos cirujanos mastólogos-oncólogos para ser sometidas en forma diferida a reconstrucción con expansor implante en una secuencia técnica de 3 tiempos quirúrgicos en un periodo comprendido entre abril del 2015 y octubre del 2020. RESULTADOS: la reconstrucción diferida habitualmente la realizamos con expansor-implante y optamos por la utilización de colgajos autólogos siempre cuando se hubiera irradiado la mama enferma. En 4 de 5 pacientes realizamos la reconstrucción del complejo areola pezón (CAP), 3 pacientes fueron de reconstrucción unilateral y 2 de bilateral, en 2 mujeres ocupamos prótesis de doble lumen tipo anatómicos y en 3 mujeres expansor con puerto a distancia, utilizando en 2 pacientes, prótesis de forma redonda y en un implante expansor anatómico. Presentamos un caso de deflación del implante a los 3 años post reconstrucción no reportamos casos de necrosis grasa, ni cuadros infecciosos, no presentamos casos de contractura capsular y reportamos un solo caso de seroma tardío de origen traumático en una paciente de reconstrucción unilateral a los 7 meses post implante. CONCLUSIÓN: la técnica reconstructiva diferida de expansor-implante, matriz dérmica autóloga, y tejidos propios para la reconstrucción del CAP, representan una buena opción terapéutica de baja morbilidad en pacientes que no han sido sometidas a irradiación post mastectomía. Creemos que a nivel nacional aún faltan políticas en salud y conductas que beneficien a las mujeres con cáncer mamario en el camino largo del tratamiento integral de la enfermedad hasta la reconstrucción mamaria y su re inserción con funcionalidad social, laboral y emocional, para unificar criterios y protocolos entre servicios públicos, privados, ministerio de salud, secretarias regionales de salud y sociedades científicas de Mastologia y Cirugía Plástica apoyando a los pocos equipos en reconstrucción mamaria , optimizando protocolos médicos que beneficien a las pacientes enfermos.

INTRODUCTION AND OBJECTIVE: delayed breast reconstruction or post mastectomy has a transcendental importance in women ́s life as well as part of the comprehensive and multidisciplinary treatment of breast cancer. Such aggression impacts on self-esteem and social functionality in women who for some reason were not undergoing immediate reconstruction. The objective is to describe the results achieved in mastectomized patients, through the expander-implant technique, autologous dermal matrix, fat graft and reconstruction of the nipple areola complex (NAC) with autologous tissues MATERIAL AND METHOD: it is a retrospective, longitudinal, observational and descriptive study of a small group of 5 non-irradiated mastectomized private patients who were not subjected to an immediate reconstruction at other medical centers. They came to the private practice referred by other mastologists-oncologists medical surgeons to be submitted to a delayed breast reconstruction with expander prosthesis in a 3 surgical times technique between April 2015 and October 2018. RESULTS: the delayed breast reconstruction is usually performed with expander prosthesis and for those injured breasts that had been irradiated, we use autologous flaps. In 4 out of 5 patients we performed the reconstruction of the NAC, 3 were submitted to unilateral reconstruction and 2 were bilateral, 2 women had anatomical double lumen prosthesis, 3 had expander implant with remote port at which 2 were round and one anatomical. We presented only one case of deflation 3 years later after reconstruction. We didn ́t report cases of fat necrosis nor infectious symptoms. We didn ́t have any case of capsular contracture but only a single case of late seroma after 7 months' post implant in a patient with unilateral reconstruction due to a traumatic incident. CONCLUSION: the delayed breast reconstructive technique with expander-implant, uses of autologous dermal matrix or own tissues for reconstructing the NAC, represents a good therapeutic option of low morbidity to patients who have not undergone post-mastectomy irradiation. We briefly believe that at a National level there is a lack of health policies and therapeutic behaviors that could benefit women with breast cancer on this long path from a complete treatment of this disease to breast reconstruction and its social, labor and emotional reintegration, to unify criteria and protocols between public services, private services, ministry of health, regional secretaries of health and scientific societies such as Mastology and Plastic Surgery to support the few teams in breast reconstruction and optimize medical protocols to benefits the sick patient.

Utilização de corpo adiposo bucal em comunicação oroantral / Use of body adiposo body in oroantral communication

Introdução: A comunicação oroantral tem como principais causas etiológicas os processos patológicos, traumatismos e cirurgias, sendo comum sua ocorrência durante exodontias de elementos dentários superiores posteriores devido ao íntimo contato dos ápices radiculares com o assoalho do seio maxilar. Relato de caso: Paciente do sexo feminino, com 51 anos de idade, apresentando comunicação oroantral há 6 anos após exodontia do elemento dental 16. Realizado fechamento da comunicação oroantral sob anestesia local, com tracionamento e sutura da bola de Bichat sobre a falha óssea. Após um ano de proservação, observamos a ausência de comunicação bucosinusal bem como de sintomatologia, resultando no sucesso do tratamento. Considerações Finais: A utilização do retalho pediculado do corpo adiposo bucal é uma alternativa útil para o fechamento e tratamento de comunicações bucosinusais, sendo que o deslizamento da bola de Bichat é um método seguro para fechamento de tais comunicações e que esta é uma técnica de simples execução, com poucas complicações e limitações...

Introduction: The oroantral communication has as main etiological causes the pathological processes, traumatisms and surgeries. Its occurrence during the exodontia of posterior superior dental elements is due to the intimate contact of the root apices with the floor of the maxillary sinus. Case report: A 51-year-old female patient, presenting oroantral communication 6 years ago after the dental element 16 was extubated. The oroantral communication was closed under local anesthesia with Bichat's ball traction and suture on the bone defect. After 1 year of proservation, we observed the absence of oral communication, as well as symptomatology, resulting in the success of the treatment. Final considerations: It is concluded that the use of the pedicle flap of the buccal adipose body is a useful alternative for the closure and treatment of buco sinusal communications, and the sliding of the bichat ball is a safe method for closing such communications and that this is a technique of simple execution, with few complications and limitations...

Platelet-rich plasma to rescue an ulcerated orbital dermal fat graft.

INTRODUCTION: Central graft ulceration is a rare complication of an orbital dermal fat graft caused by diminished blood supply to the implant. This study reports on the efficacy and safety of the use of a single subconjunctival injection of autologous platelet-rich plasma to rescue an ulcerated orbital dermal fat graft. METHODS: Three patients, who had undergone autologous dermal fat graft to treat their anophthalmic socket, were given a 2-mL subconjunctival platelet-rich plasma injection in the exposed graft margins. Demographic and clinical features, treatment protocol, clinical course, complications and follow-up time are reported. In the preoperative examination, all the patients presented a primary epithelial defect of the dermal fat graft. RESULTS: There were no major complications such as necrosis or infection. One patient presented a small conjunctival granuloma at 1-month follow up. Mean postoperative follow-up duration was 13 (range: 10-16) months. By 1 month, the chronic epithelial defect had resolved with the graft integrated within the orbital tissues in all cases. All patients were referred for artificial prosthesis placement. CONCLUSION: Although further work is needed, our findings suggest that a single subconjunctival platelet-rich plasma injection could be an effective, safe and economic alternative to surgery to rescue an ulcerated orbital dermal fat graft.

Oncological safety of autologous fat grafting after breast conservative treatment: a prospective evaluation.

Autologous fat graft to the breast is a useful tool to correct defects after breast conservative treatment (BCT). Although this procedure gains popularity, little is known about the interaction between the fat graft and the prior oncological environment. Evidences of safety of this procedure in healthy breast and after post-mastectomy reconstruction exist. However, there is paucity of data among patients who underwent BCT which are hypothetically under a higher risk of local recurrence (LR). Fifty-nine patients, with prior BCT, underwent 75 autologous fat graft procedures using the Coleman's technique, between October 2005 and July 2008. Follow-up was made by clinical and radiologic examination at least once, after 6 months of the procedure. Mean age was 50 ± 8.5 years, and mean follow-up was 34.4 ± 15.3 months. Mean time from oncological surgery to the first fat grafting procedure was 76.6 ± 30.9 months. Most of patients were at initial stage 0 (11.8%), I (33.8%), or IIA (23.7%). Immediate complication was observed in three cases (4%). Only three cases of true LR (4%) associated with the procedure were observed during the follow-up. Abnormal breast images were present in 20% of the postoperative mammograms, and in 8% of the cases, biopsy was warranted. Autologous fat graft is a safe procedure to correct breast defects after BCT, with low postoperative complications. Although it was not associated with increased risk of LR in the group of patients studied, prospective trials are needed to certify that it does not interfere in patient's oncological prognosis.

Lipoenxertia nas mamas: procedimento consagrado ou experimental? / Breast far grafting: experimental or established procedure?", "_e": "n

Atualmente vem ocorrendo aumento da incidência de utilização de enxertia de gordura para correção de defeitos mamários congênitos ou adquiridos e para tratamento mamário estético. Esse aumento é decorrente do surgimento de novas técnicas de lipoenxertia, que produzem resultados mais duradouros e confiáveis, apesar da crença de alguns autores de que o procedimento possa dificultar o rastreamento do câncer mamário. Esta revisão de literatura tem como objetivo identificar as técnicas de lipoenxertia mamárias mais utilizadas, avaliá-las quanto à eficácia e à segurança, e relatar as principais complicações associadas. A revisão foi realizada nas bases de dados PubMed e LILACS, e os fatores de inclusão foram: artigos em idioma inglês, publicados nos últimos cinco anos. Como resultado observou-se aumento do número de trabalhos abordando o tema nos últimos anos, e predomínio de uma técnica de lipoenxertia específica. A maioria dos trabalhos demonstra que a lipoenxertia mamária não prejudica o rastreamento radiológico para câncer mamário, e alguns sugerem que a gordura enxertada potencializa o desenvolvimento de câncer nas mamas. Apesar do aumento do número de trabalhos, existem ainda poucos com bom nível de evidência científica. Esta revisão permitiu concluir que a lipoenxertia é uma técnica alternativa para reparação de defeitos mamários e discreto aumento estético das mamas, devendo ser utilizada por cirurgiões com treinamento adequado e acompanhada por equipe de radiologia experiente em imagenologia mamária. Mais trabalhos com metodologia científica adequada são necessários para avaliar a lipoenxertia mamária.

There has recently been an increase in the use of fat grafting for the correction of congenital or acquired breast deformities and for aesthetic breast treatment. This increase is due to the emergence of novel fat grafting techniques that produce lasting and reliable results despite some authors' beliefs that the procedure might hinder breast cancer screening. This literature review aims to identify the most frequently used breast fat grafting techniques, evaluate their efficacy and safety, and report their major complications. The review was performed after a search in the PubMed and LILACS databases, and only English-language articles published over the past 5 years were assessed. There have been an increased number of studies on the topic in recent years, and a specific fat grafting technique has been primarily reported. Most studies in this area have shown that breast fat grafting does not affect radiological breast cancer screening, whereas some studies have suggested that the use of grafted fat may enhance the development of breast cancer. Despite the increased number of published studies, few have a good level of scientific evidence. This review concludes that fat grafting is an alternative technique for the correction of breast deformities and moderate aesthetic breast enlargement and should be performed by properly trained surgeons accompanied by a radiology team that is experienced in breast imaging. Further studies with appropriate scientific methodologies are needed to evaluate breast fat grafting.
