Neo-omphaloplasty in anchor-line abdominoplasty performed in patients who have previously undergone bariatric surgery

INTRODUCTION: In formerly morbidly obese individuals, major weight loss after bariatric surgery leads to the development of extensive areas of sagging skin with large fat deposits that mainly affect the limbs, several regions of the trunk, and the anterior abdominal wall in particular. The gold standard procedure, anchor-line abdominoplasty (also known as inverted T), is performed with the simultaneous removal of the navel followed by neo-umbilicoplasty during surgery. In the present report, we describe our experience with neo-omphaloplasty in anchor-line abdominoplasty performed in patients who previously underwent bariatric surgery. The neo-omphaloplasty mainly consists of 2 skin flaps bilaterally positioned at the extremities of the skin incision, facilitating a natural appearance of the navel after they are sutured to the fascia. METHODS: From March 2011 to June 2012, 50 patients, who previously underwent bariatric surgery and had stable body weight for at least 6 months, were operated on at the Plastic Surgery Service of the Clinics Hospital of the Faculty of Medicine of the University of Campinas. RESULTS: In the 50 patients, the neo-umbilicus was positioned at a location that was preoperatively established, and these patients exhibited characteristics similar to individuals who had not undergone abdominal surgeries. There was no evidence of dehiscence, necrosis, stenosis, suture line enlargement in the neo-umbilicus, or seroma formation in this cohort. CONCLUSIONS: When neo-omphaloplasty is performed using 2 skin flaps conventionally positioned in the abdominal wall, at a distance varying between 16 and 18 cm from the xiphoid process, the aesthetic outcomes are similar to the natural appearance of the navel. This technical approach is quick and easy to implement.INTRODUÇÃO: As grandes perdas ponderais pós-cirurgia bariátrica resultam, nos ex-obesos mórbidos, em grande flacidez cutânea nas áreas mais volumosas, com maiores depósitos adiposos nos membros, nas diversas regiões do tronco e, particularmente, na parede anterior do abdome. A abdominoplastia em âncora, também chamada tipo T invertido, tem sido o procedimento de eleição pelos especialistas, com ressecção concomitante do umbigo, seguida da neoumbilicoplastia no ato operatório. O objetivo do presente estudo é descrever nossa experiência com a técnica de neo-onfaloplastia no decurso das abdominoplastias em âncora em pacientes pós-cirurgia bariátrica, que consiste, basicamente, na utilização de 2 retalhos cutâneos, bilateralmente posicionados nas bordas da pele incisada, que, suturados à fáscia, determinam a umbilicação de aspecto natural. MÉTODO: Entre março de 2011 e junho de 2012, foram operados, pela Disciplina de Cirurgia Plástica do Hospital das Clínicas da Faculdade de Medicina da Universidade de Campinas, 50 pacientes submetidos a cirurgia bariátrica prévia, com estabilização do peso corpóreo por, no mínimo, 6 meses. RESULTADOS: Nos 50 pacientes operados, o neoumbigo ficou posicionado no local estabelecido pré-operatoriamente, apresentando características semelhantes às de indivíduos sem histórico de cirurgia abdominal prévia. Não ocorreram deiscência, necrose, estenose, alargamento das linhas de sutura no neoumbigo ou seromas nessa série de casos. CONCLUSÕES: A neo-onfaloplastia com emprego de 2 retalhos cutâneos e padronização de seu posicionamento na parede abdominal, distante 16 cm a 18 cm do apêndice xifoide, permitiu resultado estético compatível com o aspecto natural da cicatriz umbilical. Essa abordagem técnica é de fácil e rápida execução.11411

Use of trichloroacetic acid for closure of lesion by extensors in lobules of ears

Introduction: The use of ear lobe extenders causes a circular defect whose closure becomes a challenge for the plastic surgeon. There are multiple techniques with mobilization of local flaps in an attempt to close and return to the natural shape of the lobe. We propose to present trichloroacetic acid (TCA) as an alternative for the correction of these lesions. Methods: A total of five patients with lesions by ear skin eyelets were selected, and 90% TCA was used to close the defects. Results: After applying the product, in the first days, there was a hyperemia around the area where the acid was applied. The frosting area was replaced by a crust, which loosened over the days, concomitantly reducing the diameter of the lesion with progressive closure of the defect. Conclusion: Although more studies are needed, the use of 90% TCA proved to be a simple and practical option for the closure of enlarged ear lobes

Scalp reconstruction with large dorsal muscle-free flap after dog bite scalping

Introduction: Scalping is characterized by trauma in the scalp region, which can be classified as partial or total. Scalping trauma is extremely mutilating and stigmatizing, especially when exposing the bone without periosteum, leading to chronic osteomyelitis and external table erosion. When there are extensive scalp lesions above 200cm2, and with periosteum, the lesion is required a large amount of tissue with microsurgical flap, which is not available in all centers. This work aims to report a case of a 69-year-old female patient who suffered trauma due to total avulsion of a big scalp of 550cm2 with exposure of a skull cap without periosteum and total unviability of the scalp after a dog bite. Due to the total unviability of the avulsed scalp, we opted to transplant a large dorsal muscle free flap with microvascular anastomosis of the thoracodorsal pedicle with the superficial temporal vessels. The flap evolved with good perfusion, and partial grafting was performed in the bloody area. Methods: Retrospective analysis of the medical records of the patient in question. This paper follows the Declaration of Helsinki's standards and the approval of the Ethics and Research Committee. Conclusion: The free flap of the large dorsal muscle proved effective in this case of reconstruction of the scalp's extensive lesion (550cm2) with partial periosteum lesion due to scalping. The flap recovered the shape of the skull and the protective function of the skull cap

Scalp reconstruction with expanded flap

Introduction: The presence of extensive scalp defects is a major reconstructive challenge for the plastic surgeon. These defects have a vast etiology, such as traumatic, thermal or electrical burns, benign and malignant or congenital tumor resections, radiotherapy treatments sequelae, and infections. Noting that injuries such as scalping and burns (thermal or electrical), generate significant repercussions such as severe tissue loss, chronic osteomyelitis or minor sequelae such as scar alopecia. This study aims to report a case of late scalp reconstruction with a tissue expander and posterior advancement flap, due to cicatricial alopecia, in an 11-year-old female, victim of scalding by hot water in the right frontotemporal region. Methods: It was performed a retrospective analysis of the patient's medical record. The present work follows the standards of the Helsinki ethics committee. Conclusion: The scalp tissue expansion technique by stages and subsequent scalp advancement flap performing proved to be effective in restoring the patient's hair structure and hairline with minimal local distortion, restoring the scalp's shape and aesthetics of the patient
