A crescente demanda pelo explante de silicone mamário: um novo cenário para cirurgia de mamas / Growing demand for silicone breast explants: a new scenario for breast surgery

Introdução: A remoção de implantes mamários de silicone é uma cirurgia com crescente notoriedade. O avanço nos estudos sobre o linfoma BIA-ALCL (Breast Implant Associated Anaplastic Large Cell Lymphoma) e patologias inflamatórias/autoimunes relacionadas aos implantes, como a síndrome de ASIA (Autoimmune Syndrome Induced by Adjuvants), tem gerado desconforto em muitas pacientes, que optam pela sua retirada. Essa demanda traz ao cirurgião um cenário muitas vezes desafiador, no qual é preciso devolver às mamas um formato anatômico e esteticamente agradável após a retirada desse material. O objetivo é demonstrar estratégias cirúrgicas para o explante mamário de silicone. Métodos: Foram avaliadas 20 pacientes submetidas ao explante mamário, entre setembro de 2020 e março de 2021, incluindo explantes simples e associados à mastopexia. A indicação cirúrgica foi a demanda explícita das pacientes, motivadas por queixas como receio de patologias associadas, descontentamento estético, desconforto nas mamas, sintomas sistêmicos, desejo de não ter mais implantes, contratura capsular, rotação ou ruptura dos mesmos. As técnicas cirúrgicas são descritas. Resultados: Foi realizado o explante simples em 7 pacientes e em 13 foi feito o explante com mastopexia. Em 17 pacientes foi associada a lipoenxertia. A capsulectomia foi executada em todos os casos. Nas mastopexias, usamos o retalho dermoglandular de pedículo inferior para preservação de tecido mamário, associando também a lipoenxertia. Conclusão: As técnicas descritas conseguem devolver às mamas formato satisfatório, com baixas taxas de complicação e bom nível de aceitação das pacientes. Apesar das patologias relacionadas aos implantes de silicone até o momento mostrarem-se estatisticamente raras, é fundamental que estejamos atentos a sintomas e capacitados para oferecer opções cirúrgicas para o explante.

Introduction: Breast implants explantation surgery has been increasing in notoriety. Advances in studies on lymphomas BIA-ALCL (Breast Implant Associated Anaplastic Large Cell Lymphoma) and inflammatory/autoimmune pathologies related to the implants, like ASIA (Autoimmune Syndrome Induced by Adjuvants), has generated discomfort in many patients that choose to remove it. This type of demand, where it is necessary to return the breasts to an anatomical and aesthetically pleasing shape after the removal of the implants, might be a challenge for surgeons. The objective is to demonstrate surgical strategies for breast silicone explantation. Methods: Twenty patients who underwent the breast explantation surgery between September 2020 and March 2021 were evaluated. The surgical indication was always the patients demand, motivated by fear of associated pathologies, aesthetic dissatisfaction, discomfort in the breasts, systemic symptoms, desire to have no more breast implant, capsular contracture, rotation or rupture of the implant. Surgical techniques are described. Results: The simple explant was performed in 7 patients, and in 13 the explant was performed with mastopexy. In 17 patients, fat grafting was associated. Capsulectomy was performed in all cases. In mastopexies, we used the inferior dermoglandular flap to preserve breast tissue, also associating fat grafting. Conclusion: Techniques described are able to return the breasts to a satisfactory shape, with low complication rates and good levels of patient acceptance. Despite the pathologies related to silicone implants so far show themselves statistically rare, it is essential that we are attentive to symptoms and trained to provide surgical strategy for the explant.

Reconstrução de columela com enxerto condrocutâneo após lesão causada por CPAP / Columellar reconstruction with chondrocutaneous graft after injury caused by CPAP

Introdução: A pressão positiva contínua nas vias aéreas nasais (CPAP) é uma forma não invasiva de ventilação utilizada em recém-nascidos prematuros em unidades de terapia intensiva. Porém, ela pode acometer o nariz destes pacientes, evoluindo até mesmo com isquemia e necrose columelar. Diversas técnicas são descritas para reconstruir a columela, como enxertos de pele, enxertos compostos, retalhos locais e retalhos livres; mas o enxerto composto condrocutâneo auricular tem se destacado. O objetivo deste trabalho é descrever um caso de necrose de columela por uso de CPAP com reconstrução utilizando enxertia condrocutânea auricular posterior. Relato do Caso: Paciente do sexo feminino, parda, com história de prematuridade e uso prolongado de CPAP quando recém-nascida devido à síndrome da membrana hialina, evoluiu com necrose de columela. Foi submetida à enxertia composta condrocutânea auricular posterior para reconstrução da columela. A paciente apresentou resultado cirúrgico satisfatório, evoluindo com 100% de vitalidade do enxerto. Discussão: A necrose columelar associada ao uso do CPAP pode ser estética e funcionalmente debilitante, e representa um desafio reconstrutivo. As opções para obter resultados aceitáveis são limitadas, porém o uso de enxertos de orelha é tecnicamente simples, utiliza tecidos doadores estruturalmente semelhantes, não provoca cicatrizes adicionais no nariz, é realizado em um tempo cirúrgico e geralmente tem um resultado muito bom. A enxertia composta auricular posterior para reconstrução columelar se mostrou segura, com resultado estético e funcional satisfatório e mínima morbidade da área doadora.

Introduction: Continuous positive pressure in the nasal airways (CPAP) is a non-invasive form of ventilation used in premature newborns in intensive care units. However, it can affect the nose of these patients, even evolving with ischemia and columellar necrosis. Several techniques are described to reconstruct the columella, such as skin grafts, composite grafts, local flaps, and free flaps, but the atrial chondrocutaneous graft has stood out. This study aims to describe a case of columella necrosis using CPAP with reconstruction using posterior atrial chondrocutaneous grafting. Case Report: A brown, female patient, with a history of prematurity and prolonged use of CPAP when she was born due to hyaline membrane syndrome, developed columella necrosis. The patient underwent posterior auricular chondrocutaneous grafting to reconstruct the columella. She presented a satisfactory surgical result, evolving with 100% graft vitality. Discussion: Columellar necrosis associated with the use of CPAP can be aesthetically and functionally debilitating, and represents a reconstructive challenge. The options for obtaining acceptable results are limited. However, the use of ear grafts is technically straightforward, uses structurally similar donor tissues, does not cause additional scarring on the nose, is performed in a surgical period, and generally has an excellent result. Posterior auricular composite grafting for columellar reconstruction proved safe, with satisfactory aesthetic and functional results and minimal morbidity in the donor area.

Nine-year follow up after hematopoietic stem cell transplantation in five multiple sclerosis patients / Nove anos de seguimento após transplante autólogo de células tronco hematopoiéticas em cinco pacientes com esclerose múltipla

ABSTRACT Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system. Its treatment has focused on inflammation control as early as possible to avoid disability. Autologous hematopoietic stem cell transplantation (AHSCT) has been used for treating MS since 1996, with recent decisive results regarding benefits in long-term efficacy. Five patients followed up at an MS center in Belo Horizonte, Brazil, who had relapsing-remitting MS with high disease activity, underwent AHSCT between 2009 and 2011. They were evaluated clinically, with magnetic resonance imaging, and by the EDSS every six months after transplantation, up to July 2018. The patients were four women and one man, with ages ranging from 25-50 years, and time since disease onset ranging from 4-17 years at the time of the procedure. Four patients improved, one patient was stabilized, and all patients were free of disease activity after 5-9 years. Through improving patient selection and decreasing the time from disease onset, AHSCT could stop epitope spreading and disease progression. Despite multiple other therapeutic choices being approved for relapsing-remitting MS, AHSCT continues to be a treatment to consider for aggressive MS disease.

RESUMO A esclerose múltipla é uma doença imunomediada do sistema nervoso central. Seu tratamento tem sido focado no controle da inflamação o mais cedo possível para evitar incapacidade. O transplante autólogo de células tronco hematopoiéticas (TACTH) vem sendo usado para tratar esclerose múltipla desde 1996, e recentes resultados foram decisivos a respeito do benefício na eficácia a longo prazo. Cinco pacientes seguidos num centro de esclerose múltipla de Belo Horizonte, Brasil, que apresentavam forma clínica remitente recorrente com alta atividade de doença foram submetidos a esse tratamento de 2009 a 2011. Após o transplante foram avaliados clinicamente e com ressonância magnética, e escala de EDSS, a cada seis meses até julho de 2018. Os pacientes eram quatro mulheres e um homem, com idade entre 25 e 50 anos e tempo de doença variando de 4 a 17 anos na época do procedimento. Quatro pacientes melhoraram após a primeira avaliação e um manteve-se estável. Todos os pacientes permaneceram sem evidência de doença clínica ou radiológica de 5 a 9 anos após. Com uma seleção cada vez mais criteriosa de pacientes o TACTH pode interromper a disseminação do epítopo e controlar a progressão da doença. Apesar de várias outras opções terapêuticas aprovadas para esclerose múltipla o TACTH continua a ser uma forma de tratamento a ser considerada em casos de doença muito agressiva.

Bone Flap Changes after Cranioplasty Using Frozen Autologous Bone Flaps: A Three-Dimensional Volumetric Reconstruction Study

PURPOSE: Bone flap resorption (BFR) after cranioplasty with an autologous bone flap (ABF) is well known. However, the prevalences and degrees of BFR remain unclear. This study aimed to evaluate changes in ABFs following cranioplasty and to investigate factors related with BFR. MATERIALS AND METHODS: We retrospectively reviewed 97 patients who underwent cranioplasty with frozen ABF between January 2007 and December 2016. Brain CT images of these patients were reconstructed to form three-dimensional (3D) images, and 3D images of ABF were separated using medical image editing software. ABF volumes on images were measured using 3D image editing software and were compared between images in the immediate postoperative period and at postoperative 12 months. Risk factors related with BFR were also analyzed. RESULTS: The volumes of bone flaps calculated from CT images immediately after cranioplasty ranged from 55.3 cm³ to 175 cm³. Remnant bone flap volumes at postoperative 12 months ranged from 14.2% to 102.5% of the original volume. Seventy-five patients (77.3%) had a BFR rate exceeding 10% at 12 months after cranioplasty, and 26 patients (26.8%) presented severe BFR over 40%. Ten patients (10.3%) underwent repeated cranioplasty due to severe BFR. The use of a 5-mm burr for central tack-up sutures was significantly associated with BFR (p<0.001). CONCLUSION: Most ABFs after cranioplasty are absorbed. Thus, when using frozen ABF, patients should be adequately informed. To prevent BFR, making holes must be kept to a minimum during ABF grafting.

There is not sufficient evidence for statistical differences in the remaining indicators.@*CONCLUSION@#The current literature shows rhBMP is a safe and effective grafting material in the treatment of lumbar spondylolisthesis. Further evidence is dependent on the emergence of more randomized controlled trials with higher quality and larger sample sizes in the future.

Correction of post-traumatic enophthalmos with anatomical absorbable implant and iliac bone graft

BACKGROUND: Trauma is one of the most common causes of enophthalmos, and post-traumatic enophthalmos primarily results from an increased volume of the bony orbit. We achieved good long-term results by simultaneously using an anatomical absorbable implant and iliac bone graft to correct post-traumatic enophthalmos.METHODS: From January 2012 to December 2016, we performed operations on seven patients with post-traumatic enophthalmos. In all seven cases, reduction surgery for the initial trauma was performed at our hospital. Hertel exophthalmometry, clinical photography, three-dimensional computed tomography (3D-CT), and orbital volume measurements using software to calculate the specific volume captured on 3D-CT (ITK-SNAP, Insight Toolkit-SNAP) were performed preoperatively and postoperatively.RESULTS: Patients were evaluated based on exophthalmometry, clinical photographs, 3D-CT, and orbital volume measured by the ITK-SNAP program at 5 days and 1 year postoperatively, and all factors improved significantly compared with the preoperative baseline. Complications such as hematoma or extraocular muscle limitation were absent, and the corrected orbital volume was well maintained at the 1-year follow-up visit.CONCLUSION: We present a method to correct enophthalmos by reconstructing the orbital wall using an anatomical absorbable implant and a simultaneous autologous iliac bone graft. All cases showed satisfactory results for enophthalmos correction. We suggest this method as a good option for the correction of post-traumatic enophthalmos.

Scar dermal transposition flap for depressed scars: A valuable technique for depressed scar management

BACKGROUND: Various methods have been reported for the improvement of widened or depressed scars. However, scars can be complex at presentation. If a widened but flat portion is combined with a tethered or a depressed area, a scar revision method that can effectively resolve all issues is needed. The authors utilized a dermal portion of the widened scar as a re-adhesion barrier and filled tissue after the release of the tethering or depression. METHODS: From July 2014 to December 2017, a total of eight patients presented with combined scars with both widened and depressed areas and underwent scar revisions with scar dermal transposition flaps. The scar flap of the widened scar was de-epithelialized, leaving the dermo-cutaneous pedicle near the depressed area. Without any additional skin incision on the depressed site, the tethering was released by making a skin incision at the scar flap. The de-epithelialized scar dermal flap was transpositioned under the depressed area of the scar. RESULTS: The surgical wounds of all eight patients healed without any complications. The mean follow-up period was 5.25 months. The filling effect of the scar flap persisted without the conspicuous relapse of a depression or tethering. The patients were satisfied with the final results and the fact that no additional incision was needed for the tethered and depressed scar. CONCLUSIONS: If the depressed site is near a widened scar, a scar dermal transposition flap may be a versatile option for improving the depression without an additional skin incision.

External tissue expansion assisted lipotransfer for temple depression augmentation / 中华医学美学美容杂志

Objective To observe the clinical effects of external tissue expansion assisted lipotransfer for temple depression augmentation.Methods A total of 18 cases of temple depression wore the a vacuum-based cupping cup device for recipient-site preconditioning for 1-3 months before fat injection.Results Temple soft tissue can pinched easily after expansion,fat injection ranged from 12-16ml per site,the temple depression were augmented and the sculpted appearance were improved obviously after 1to 12 months follow-up,there were no complications such as nodules,masses,alopecia or cysts occurred.Patient satisfaction was assessed and the VAS score was (7.8.± 1.4).Conclusions The addition of temple region expansion before fat injection can improve the skin compliance,increase the recipient-site volume,enhance fat graft placement and higher graft survival rates,demonstrating a high safety and efficacy procedure.

Changes of facial volume maintenance rate after single autologous fat grafted for repaired progressive facial hemiatrophy / 中华医学美学美容杂志

Objective To measure the change of facial volume maintenance rate after autologous fat grafted for repaired progressive facial hemiatrophy by using three-dimensional digital technology.Methods 3D scanner was used to acquire facial data in 10 patients with progressive facial hemiatrophy before operation;Mimics 17.0 software was used to reconstruce patients' facial 3D model and to calculate the volume of facial tissue defect;autologous fat was grafted to repair facial deformity.The facial volume maintenance rate was calculated in all the patients 3 months and 6 months after operation.Results We had performed facial 3D data acquisition and facial repaired with autologus fat grafted in 10 patients;patients' facial morphology was improved.The mean facial volume maintenance rate was (35.80±3.44)％ in 3 months and (27.82±3.80)％ 6 months after surgery.Conclusions The mean facial volume maintenance rate in postoperative 3 months is inferior to that in 6 months in single autologous fat grafted for repairing progressive facial hemiatrophy.
