ABSTRACT

BACKGROUND: Silicone implants have gone through adaptations to improve esthetic outcomes. With the progress of technology, including gel rheology, different properties have been introduced. Ergonomic style implants (ESI) feature enhanced rheological properties and provide a shaped contour with a round base. OBJECTIVES: This study investigated outcomes for ESI in breast augmentation concerning lower pole stretching (LPS) and implant stability and describes an algorithm to assist in decision-making. METHODS: A total of 148 patients (296 breasts) underwent breast augmentation with ESI; this procedure was indicated in patients with good skin quality and <6 cm between the nipple-areola complex and the inframammary fold. RESULTS: The mean patient age was 29.6 years (range: 19-39), and 93 patients (62.8%) underwent primary breast augmentation with demi/full projection (average volume of 245 cc [175-375 cc]). Axillary incision and subfascial pocket were indicated in 115 (77.7%) and 72 (48%) cases, respectively. Average LPS values were 32.2% (24.91 mm) and 10.86% (9.42 mm) at up to 10 days and 10 days to 12 months postprocedure, respectively. Patients were followed for a mean of 29.9 ± 26.4 months (range: 6-66). Complication rates per breast and per patient were 5% and 10%, respectively, and included subcutaneous banding in the axilla (1.6%), implant displacement (1.2%), and wound dehiscence (0.8%). No cases of infection, seroma, or rippling complications were observed. CONCLUSIONS: The present decision-making algorithm summarizes the process involved in breast augmentation using ESI and is intended to help standardize decisions. With correct planning, long-lasting outcomes can be achieved due to favorable interactions between ESI and the patient's tissues.

ABSTRACT

SUMMARY: Reoperative procedures after breast augmentation are frequently more complex than primary cases because of local complications and insufficient soft-tissue coverage. Although the transaxillary incision is often indicated in primary breast augmentation, limitations of this approach include secondary surgery and correcting complications after using this approach via the same incision. Combining the transaxillary technique with a subfascial pocket has been suggested to avoid breast scarring and the limitations of submuscular pockets represented by breast animation. With advances in autogenous fat grafting (AFG) techniques, implant coverage alternatives and more natural outcomes have been reported from more superficial implant pockets. Simultaneous AFG with silicone implants (defined as hybrid breast augmentation) has been evaluated recently as an attractive procedure. These two techniques combine to provide breast projection and natural cleavage while camouflaging implant edges. AFG is also important to reduce the intermammary distance and achieve a smoother transition between the breasts. The transaxillary approach can be useful in reoperative breast augmentation and avoids additional scarring on the breast. This article and the accompanying videos provide a detailed, step-by-step guide to reoperative hybrid breast augmentation using a subfascial transaxillary approach, with a predictable and optimized surgical outcome.

ABSTRACT

SUMMARY: Advances in breast augmentation techniques have led to safety improvements and better aesthetic results. The concurrent combination of the axillary approach with a subfascial pocket has been suggested for augmentation procedures, because it avoids breast scarring and the limitations of submuscular positioning represented by breast animation when the pectoral muscle is contracted. With the improvement of autogenous fat grafting techniques, new implant coverage options and more natural results have been proposed with more superficial implant pockets; simultaneous autogenous fat grafting with silicone implants (defined as hybrid breast augmentation) has recently been evaluated as a promising technique. Combining these two procedures allows core volume projection and natural cleavage while camouflaging implant edges. Fat grafting is also useful in reducing intermammary distance and achieving a smaller and smoother transition between the breasts. This article and the accompanying videos provide a detailed, step-by-step guide to hybrid breast augmentation using a subfascial axillary approach, with a predictable and optimized surgical outcome.

ABSTRACT

BACKGROUND: Augmentation mastopexy (AM) is a challenging procedure. Complications include implant displacement and visibility, which can be addressed, but the stability of the smooth implant surface and poor soft-tissue coverage may present limitations. This article describes a surgical technique for AM using a composite reverse inferior muscle sling associated with autogenous fat grafting. METHODS: Forty-five patients (90 breasts; mean age, 37.7 ± 7.2 years) underwent hybrid composite reverse inferior muscular sling AM. An upper/medial pole area between the implant and the clavicle region and parasternal area was marked to receive fat grafting and divided into three zones. Three-dimensional imaging was used to evaluate lower pole stretch and intermammary distance. RESULTS: The average implant volume was 265 cc (range, 175 to 335 cc). The average fat volumes in zones I/II and III were 80.1 (range, 61.6 to 95.2 cc) and 39.3 (range, 25.2 to 47.3 cc), respectively. Five complications were observed in three patients (6.6%)-minor dehiscence in two (4.4%) and nipple-areola asymmetry in one (2.2%). The lower pole stretched 11.51% (9.9 mm) and 9.8% (8.5 mm) on the right and left sides, respectively ( P < 0.0001), between 10 days and 1 year postoperatively. The intermammary distance was reduced, on average, 49.9% (25.1 mm) ( P < 0.001) between the preoperative value and 1 year postoperatively. CONCLUSIONS: Hybrid composite reverse inferior muscular sling has led to improved aesthetic results for patients with breast ptosis and poor tissue coverage. Fat grafting and recognizing cleavage zones are still important to obtain satisfactory results. This procedure offers a good alternative for AM candidates, providing an adequate smooth surface for implant stabilization.

ABSTRACT

BACKGROUND: Autologous fat grafting is a procedure indicated for breast augmentation to improve coverage of silicone implants and redesign breast shape. Different techniques are based on parameters that have not been systematically standardized. The authors present a method using breast zone standardization based on breast anatomy to achieve an anatomical composite breast. METHODS: The authors performed this zone standardization in 76 breasts (38 patients) undergoing primary/secondary augmentation. The area between the implant and the clavicle and parasternal area was marked to receive fat grafting and divided into three zones. A mathematical formula [ volume of autologous fat graft = (π × r 2 × p)/4.8] was used to estimate the fat graft volume according to implant volume in the respective zones. RESULTS: Implant volumes ranged from 205 to 375 cc (mean, 265 cc), and patients received an average fat graft volume of 105.3 cc per breast (range, 36 to 135 cc); the average fat volume in zones I/II and III was 78.28 cc (range, 0 to 100 cc) and 27.03 cc (range, 15 to 60 cc), respectively. Three minor complications were observed (5.2 percent) during a mean follow-up of 12.8 months. A high correlation was observed between the fat grafting performed in the cohort and predictions obtained from the formula ( p < 0.001). CONCLUSIONS: Recognizing risky cleavage breast zones between the implant pocket and the upper and medial quadrants remains essential to attain satisfactory outcomes. Although experience and proper judgment are still important in the fat grafting technique, the data presented here offer plastic surgeons an additional standardized framework to help deliver predictable hybrid breast augmentation. . CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT

BACKGROUND: Robotic surgery is a valid option for minimally invasive surgery in most surgical specialties. However, the need to master laparoscopy is questionable before starting specific training in robotic surgery. We compared the development of basic robotic surgery skills between individuals randomized to train in conventional, laparoscopic, or robotic skills. METHODS: We conducted a single-centered, single-blinded randomized trial. Medical students were randomly assigned to 20 h of conventional, laparoscopic, or robotic surgical training. Students with previous surgical experience were excluded. Participants were evaluated pre- and post-training on the dV-Trainer robotic surgical simulator with the following exercises: Camera Targeting 1, Peg Board 1, Ring and Rail 1, and Ring and Rail 2. RESULTS: Sixty-six students were randomly assigned to each training group. Eight individuals did not complete the study (2 in the conventional group, 3 in the laparoscopic group, and 3 in the robotic group). All groups demonstrated significant improvement in the composite score and in each task following the training period (p < 0.001). No differences were seen between the conventional and laparoscopic groups in the composite score or individual tasks. The robotic group showed greater improvement in number of errors, economy of motion, workspace utilization, and time for completion compared to the other groups. The laparoscopic group showed improved camera manipulation skills compared to the conventional group, while the conventional group showed improved errors and economy of motion compared to the laparoscopic group. CONCLUSION: There was no difference in the acquisition of basic robotic surgical skills between individuals trained in basic conventional or laparoscopic surgical skills. We believe surgeons mastery in laparoscopy is not needed before initiating robotic surgical training. However, basic principles of laparoscopy remain applicable to robotic surgery. Future studies should compare transferability of conventional and laparoscopic training to robotic skills in the operating room.

ABSTRACT

Introdução: O neurinoma plexiforme gigante é um neuroectoderma e uma doença hereditária. É um tumor cutâneo incomum associado à NF1, caracterizado como um tumor benigno da bainha do nervo periférico envolvendo múltiplos fascículos nervosos. Os objetivos da reconstrução da cobertura do antebraço são proteger as estruturas que vão até o punho e a mão e evitar cicatrizes que levem à perda de movimento. Tanto o antebraço quanto a mão desempenham papéis funcionais e sociais. O manejo bem-sucedido de feridas complexas é necessário para a reabilitação funcional geral desses pacientes. Relato do Caso: Paciente do sexo feminino, 31 anos, apresentou-se na divisão de cirurgia plástica com neurofibroma plexiforme gigante no antebraço direito. Após ressecção cuidadosa, todos os tendões anteriores do antebraço foram expostos. O defeito foi coberto com Pelnac T enxertável (espessura de 3mm e tamanho 12 X 24cm2), fixados com pontos monocryl 4-0. Após 10 dias, a matriz dérmica acelular foi removida e um enxerto de malha de pele de espessura parcial foi colocado. No dia 7, a matriz dérmica acelular apresentou bons sinais de ingestão. No dia 17, observamos uma sobrevida do enxerto de 95%. No seguimento de 3 meses, a reconstrução estava estável, sem defeitos de contorno, a mão apresentava amplitude de movimento completa e o paciente não apresentava problemas nas atividades diárias. Conclusões: A matriz dérmica acelular parece ser uma opção útil na cobertura de defeitos complexos no antebraço, permitindo menor morbidade e rápida recuperação funcional.


Introduction: Giant plexiform neurinoma is a neuroectoderm and inherited disease. It is an uncommon skin tumor associated with NF1, characterized as a benign peripheral nerve sheath tumor surrounding multiple nervous fascicles. The goals of forearm coverage reconstruction are to protect the structures running to the wrist and hand and prevent scarring that leads to movement loss. Both forearm and hand play functional and social roles. Successful management of complex wounds is necessary for the overall functional rehabilitation of these patients. Case Report: A 31-year-old woman presented at the plastic surgery division with a giant plexiform neurofibroma in the right forearm. After careful resection, all anterior forearm tendons were exposed. The defect was covered with graftable Pelnac T (thickness of 3mm and sizing 12 X 24cm2), fixed with 4-0 monocryl sutures. After 10 days, the acellular dermal matrix silicone layer was removed, and a split-thickness skin meshed graft was placed. On day 7, the acellular dermal matrix showed good signs of intake. On day 17, we observed a 95% graft survival. At the 3-month follow-up, reconstruction was stable without contouring defects, the hand had full range of motion, and the patient had no problems in daily activities. Conclusions: Acellular dermal matrix appears to be a useful option in covering complex defects in the forearm, allowing for less morbidity and rapid functional recovery.

ABSTRACT

BACKGROUND: Reoperative augmentation mammoplasty (RAM) is a challenging procedure, with the highest rates of complications and revision. Complications include implant malposition, lateral displacement, bottoming out, and rotation. These deformities can be addressed with various procedures, but the pocket control and stability of the new smooth implant surface may present limitations. OBJECTIVES: This study revisits a previously described predictable approach in primary breast augmentation and defines a surgical treatment algorithm for RAM technique selection. METHODS: Between 2017 and 2021, 72 patients (144 breasts) underwent RAM with composite reverse inferior muscle sling (CRIMS) technique and its technical variations (types I-IV). CRIMS technique involves placing a silicone gel implant into the submuscular (SM) pocket with an inferior sling of the pectoralis major muscle based on the dimensions of the implant, in combination with support points/dermal bridge sutures to stabilize the implant and glandular tissue at the lower breast pole (LBP). Reasons for surgery were ptosis (92%), implant and malposition (59.6%). Patients were followed for at least 6 months in 5 cases (6.9%), at least 12 months in 50 cases (69.4%), for at least 36 months in 10 cases (13.8%), and more than 36 months in 7 cases (9.7%) (mean 34 months; range 6-48 months). Patients were evaluated in terms of resolution of symptoms, satisfaction, and complications. Three-dimensional imaging (3DI) obtained from the Divina scanner system was used and followed up for 1 year to evaluate breast position, lower pole stretch (LPS), and intermammary distance (IMD). RESULTS: Eleven cases of minor complications were observed in 9 patients (12.5%): hypertrophic scarring in 4 (5.5%), wound dehiscence in 4 (5.5%), Baker II/III capsular contracture in 1 (1.3%). SmoothSilk surface silicone implants were used in all cases, with an average volume decrease of 120 cc. Sixty-eight patients (94.4%) were either very satisfied/satisfied with their aesthetic result. Breast images were performed in a group of 65 patients (90.2%), and in 7 breasts (10.7%), localized oil cysts were observed. The value for LPS was 7.87% (p <0.0001) between 10 days and 1 year, with the majority occurring early in the first 3 months, indicating that the LBP/implant remains steady during the last months of follow-up. No cases of fat necrosis/seroma were observed. There were no signs of intra/extracapsular ruptures, capsular contracture. There were 2 cases (3%) of minimal implant displacement and no cases of rotation. CONCLUSIONS: CRIMS and its variations can be performed successfully in RAM. An algorithmic approach can facilitate the pre- and intraoperative decision-making process and provide the new pocket control and implant stability with acceptable complication rates. Further accurate evaluation is recommended to understand the benefits or disadvantages of CRIMS compared to other RAM techniques.

ABSTRACT

BACKGROUND: Simultaneous association of autologous fat grafting (AFG) with silicone implants, defined as a hybrid procedure, has been proposed for breast augmentation (BA). In some patients, larger-volume implants may result in larger incisions, with long-term effects including implant palpability, soft tissue atrophy, and secondary ptosis. Some patients do not want large volume implants, or have insufficient soft tissue coverage. Recent improvements in AFG have led to new surgical options in BA for addressing these cases. OBJECTIVES: This study combines AFG in BA using small-volume implants, known as the SWEH (soft weight hybrid) approach, and evaluates aesthetic advantages and outcomes following primary/secondary BA. METHODS: 25 patients (50 breasts) underwent SWEH procedures; this approach was indicated when the overlying tissue was insufficient to adequately cover the implant and patients refused large-volume implants. Three-dimensional images were obtained using a Divina 3D scanner system (AX3 Technologies, Miami, USA) to assess breast volume (BV) and intermammary distance (IMD) during follow-up. RESULTS: Mean patient age was 29.3 years (range: 21-42) and mean body mass index was 19.3 kg/m2 (15.3-27.2). The most common implant (SmoothSilk surface Round/Ergonomix style) volume was 180 cc (175-215), and patients received a mean volume of 125 cc of fat (89-168)/breast in the subcutaneous tissue. Preoperative average BV measurements were 236.85 cc (170-335). At 3 and 12 months post-procedure, the average BV values were 488.82 and 478.73cc, respectively (p=0.475). The average preoperative IMD was 31.76 mm (range, 22-43); at 3 and 12 months post-procedure, the average IMD was 20.47 and 20.94 mm, respectively (p=0.61). Postoperative complications included subcutaneous banding in the axilla (n = 1; 4%) and hypertrophic scarring (n = 1; 4%). Breast imaging exams were performed; in 2 breasts (8%) localized oil cysts were observed; no cases of suspicious calcifications, fat necrosis, or lumps were seen. Fat retention rate (1 year) was calculated by the difference between the BV expected with 100% fat intake and the real BV observed. In our sample we observed an average of 72.7 (range: 69.2-77.3, SD: 2.63) and 76.7 (range: 72.3-79.9, SD: 2.18) percent of fat intake on the right and the left breast respectively. No rippling, implant malposition, or infection was observed during a mean follow-up of 22 months (6-40). CONCLUSIONS: SWEH is a useful surgical alternative that combines the benefits of AFG and implant-based augmentation, particularly with regard to soft tissue coverage, and avoids the limitations of larger-volume implants. The association of small-volume gel implants and smaller scars can yield satisfactory aesthetic outcomes.

ABSTRACT

Introdução: O enxerto de gordura nano melhora a qualidade da pele nos danos secundários ao envelhecimento e nas sequelas cicatriciais. Apresentamos resultados iniciais do enxerto de gordura nano com o uso de um dispositivo descartável de baixo custo propondo uma padronização da sua utilização conforme a área a ser tratada. Métodos: Foi realizada uma coorte prospectiva de julho de 2019 a março de 2020. O critério de inclusão foi pacientes que realizaram enxerto de gordura nano para tratamento da pele. Já o critério de exclusão foi a realização prévia de algum tratamento invasivo da pele. Foram analisadas 20 pacientes consecutivas que preencheram os pré-requisitos. Os resultados foram avaliados no 6º mês de pós-operatório. As pacientes responderam um questionário, classificando de 1 - muito ruim a 10 - excelente, as alterações na qualidade da pele. Resultados: As vinte pacientes acompanhadas não apresentaram nenhuma complicação pós-operatória. O edema após aplicação reduziu entre três e sete dias. Não houve hematoma nem infecção. As pacientes que realizaram somente enxerto de gordura nano, sem outra cirurgia associada, conseguiram voltar às suas atividades após 24 horas. Os escores relatados pelas pacientes com 6 meses foram entre 7 e 10, com média de 8. Conclusão: A utilização do sistema Smartneedle™ para a enxertia de gordura nano apresenta resultados na satisfação das pacientes semelhante aos outros métodos de aplicação e permite uma distribuição uniforme e padronizada do enxerto conforme a região anatômica, além de otimizar o tempo cirúrgico.


Introduction: Nanofat graft improves skin quality in damage secondary to aging and scar sequelae. We present the initial results of the nanofat graft using a low-cost disposable device, proposing a standardization of its use according to the area to be treated. Methods: A prospective cohort was conducted from July 2019 to March 2020. The inclusion criterion was patients who underwent nanofat grafting for skin treatment. The exclusion criterion was the previous performance of some invasive treatment of the skin. Twenty consecutive patients who met the prerequisites were analyzed. The results were evaluated in the 6th postoperative month. The patients answered a questionnaire, classifying from 1 - very bad to 10 - excellent, changes in skin quality. Results: The twenty patients followed did not present any postoperative complications. Edema after the application was reduced between three and seven days. There was no hematoma or infection. Patients who underwent only nanofat grafting without another associated surgery could return to their activities after 24 hours. The scores reported by patients at 6 months were between 7 and 10, with a mean of 8. Conclusion: The use of the Smartneedle™ system for nanofat grafting presents patient satisfaction similar to other application methods and allows a uniform and standardized distribution of the graft according to the anatomical region and optimizing surgical time

ABSTRACT

BACKGROUND: Simultaneous application of the axillary approach (AA) with the subfascial pocket (SF) has been proposed for breast augmentation (BA) surgery. New silicone implant technology and recent improvements in autologous fat grafting (AFG) have ushered in a new era for BA. OBJECTIVES: The aim of this study was to present the combined subfascial ergonomic axillary hybrid (SEAH) method and evaluate its aesthetic benefits after primary/secondary BA. METHODS: In total, 42 patients (84 breasts) underwent BA with the SEAH technique; this approach was indicated when the overlying tissue was insufficient to adequately cover the implant. RESULTS: Mean patient age was 34.6 years (range, 28-56 years), mean BMI was 18.8 kg/m2 (range, 14.4-26.1 kg/m2). The most common implant (Motiva SmoothSilk surface Ergonomix style) volume was 255 cc (range, 175-355 cc), patients received a mean fat volume of 96 mL (range, 60-145 mL) per breast in the subcutaneous tissue. The average lower pole stretch value was 40.5% (21.75 mm) and 13.1% (9.9 mm) for preoperative to 10 days postprocedure and 10 days to 18 months postprocedure, respectively. Postoperative complications included subcutaneous banding in the axilla (n = 3, 7.1%), small wound dehiscence (n = 1, 2.3%), and hypertrophic scarring (n = 1, 2.3%). No rippling, implant malposition, infection, or fat necrosis was observed during a mean follow-up of 18 months (range, 6-32 months). CONCLUSIONS: SEAH is a useful and versatile technique combining the benefits of AFG and implant-based augmentation, particularly with regard to soft tissue coverage, and avoids the limitations of the submuscular position. The combination of ergonomic gel implants and a SF pocket can yield satisfactory aesthetic outcomes.

ABSTRACT

BACKGROUND: Up to 25% of otoplasties can lead to complications, indicating the need for technical refinement. Stenström's anterior auricular cartilage scoring is used in combination with Mustardé's technique to treat the antihelix deformity in several series, with good results. Both can be performed with different instruments such as rasps or puncture needles. OBJECTIVES: This study aims to compare the use of puncture needles and rasps for anterior cartilage scoring in otoplasty. The association of Stenström and Mustardé were the basic technique. Anatomical and aesthetic endpoints were assessed. We also reviewed postoperative complications. METHODS: Forty-two patients with prominent ears and no previous surgery were randomly assigned needle or rasps technique. They were operated on by the first-year plastic surgery resident in the years of 2014 and 2019. The patients were followed up and reviewed at days 2 and 15, as well as 1, 3 and 6 months postoperatively. The endpoints were evaluated through pre- and postoperative photographs by four experienced plastic surgeons unaware of the techniques used in each case. Patient satisfaction was searched by a "yes" or "no" question. Surgical time and postoperative edema were evaluated in 20 patients (2014 group). RESULTS: There were no statistical differences between the groups in terms of overall results, symmetry, antihelix shape or cartilage fracture. Ninety-five percent of the patients were satisfied with the outcome. The needle technique resulted in less postoperative edema and shorter surgical time. CONCLUSION: Anterior cartilage scoring used in combination with posterior mattress sutures to treat poorly formed antihelical fold has good and similar results when performed with rasps or puncture needles, even in unexperienced hands. The needle has the advantage of leading to a comparable surgical time and less postoperative edema, while not requiring any special surgical instrument.

ABSTRACT

BACKGROUND: Autogenous fat grafting (AFG) is an established technique used as an adjunct to breast augmentation (BA) to redesign breast shape. Surgeons often use experience and intuition to estimate AFG volume, which can result in incorrect assessment of donor areas and unnecessary fat removal. OBJECTIVES: This aim of this study was to develop a method based on a mathematical formula, which utilizes implant volume and projection to predict AFG volume. METHODS: Thirty patients (60 breasts) underwent primary hybrid BA. A software package (SketchUp) was used to simulate 3-dimensional AFG and implant volumes, which in turn were used to develop an equation for estimating AFG volume according to 3 different implant projections. The results for each group were compared, via Pearson's correlation coefficient, with the results of the clinical series. RESULTS: All patients received Motiva Ergonomix SmoothSilk/SilkSurface implants, ranging in volume from 175 to 355 cc (mean, 265 cc), as well as an average AFG volume of 79.2 cc/breast (range, 50-110 cc). Twenty-nine patients (96.6%) were either very satisfied or satisfied during a mean follow-up of 18 months (range, 6-28 months). A high correlation was observed between the AFG performed in the cohort and predictions obtained from the formula (r = 0.938, P < 0.001). CONCLUSIONS: The AFG volume in hybrid BA procedures can be estimated utilizing measurements based on implant volume/projection. This low-cost method can be applied to guide surgical decision-making in patients who are candidates for BA.

ABSTRACT

Introdução: Abdominoplastia é um dos procedimentos cirúrgicos estéticos mais realizados. Seroma é a complicação local mais comum associada com abdominoplastia, com uma incidência média de 10%. A maior incidência de seroma pós-operatório (PO) ocorre no décimo primeiro dia PO. Ecografia abdominal é o método de escolha para o diagnóstico de seroma após abdominoplastia. Novas técnicas surgiram ao longo dos anos na tentativa de trazer melhores resultados estéticos com menos complicações, como lipoabdominoplastia descrita por Saldanha. Porém, estudos anatômicos recentes questionam a necessidade da manutenção da fáscia de Scarpa descrita na técnica de lipoabdominoplastia, descrevendo que em torno de 90% do sistema linfático abdominal está no plano subdérmico e 10% em um sistema linfático profundo justa-aponeurose abdominal. O objetivo é comparar a incidência de seroma na lipoabdominoplastia sem preservação da fáscia de Scarpa com a abdominoplastia clássica. Métodos: Coorte prospectiva, cega na qual serão analisados 40 pacientes consecutivos que realizaram abdominoplastia sem lipoaspiração associada (n = 20) ou lipoabdominoplastia (n = 20) no Hospital de Clínicas de Porto Alegre entre abril de 2016 e maio de 2017. Todos foram submetidos à ecografia de parede abdominal no 10o dia PO. Resultados: A incidência de seroma foi de 5% (n = 1) no grupo de abdominoplastia clássica e de 10% (n = 2) no grupo de lipoabdominoplastia, sem diferença estatística. Conclusão: Estes resultados, neste grupo de pacientes, mostram que não houve diferença estatística entre os dois grupos.


Introduction: Abdominoplasty is among the most commonly performed surgical procedures. Seroma is the most common local complication associated with abdominoplasty, with an average incidence of 10%. The highest incidence of postoperative (PO) seroma occurs on the eleventh postoperative day (POD). Abdominal ultrasound is the method of choice for diagnosing seroma after abdominoplasty. New techniques have emerged aiming to improve aesthetic results with fewer complications, such as lipoabdominoplasty described by Saldanha. However, recent anatomical studies have questioned the need for Scarpa fascia preservation recommended in the lipoabdominoplasty technique, describing that around 90% of the abdominal lymphatic system is in the subdermal plane, while the other 10% is in a deep lymphatic system near the abdominal aponeurosis. The objective is to compare the incidence of seroma in lipoabdominoplasty without Scarpa fascia preservation to that in classic abdominoplasty. Methods: Prospective blinded cohort in which 40 consecutive patients who underwent abdominoplasty without associated liposuction (n = 20) or lipoabdominoplasty (n = 20) at the Hospital de Clínicas of Porto Alegre between April 2016 and May 2017 were analyzed. All patients underwent abdominal wall ultrasonography on the tenth POD. Results: The incidence of seroma was 5% (n = 1) in the classic abdominoplasty group and 10% (n = 2) in the lipoabdominoplasty group, with no statistical difference. Conclusion: These results showed no statistically significant intergroup difference in seroma development.

ABSTRACT

Introdução: A reconstrução nasal é a mais antiga das cirurgias plásticas. A anatomia nasal é complexa e necessita de uma associação de técnicas para a restauração da função e estética nasal adequada. Pereira et al. descreveram uma técnica que possibilita a reconstrução nasal total da cartilagem alar, com o uso de um enxerto da cartilagem auricular, com mínima deformidade auricular secundária à retirada do enxerto. O objetivo deste trabalho é apresentar uma modificação da técnica acima descrita, que possibilita reconstruir mais uma região anatômica do nariz, sem aumentar a morbidade, realizada por Collares et al., e a sua inserção no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre. Métodos: Foi realizado um estudo retrospectivo. Avaliou-se a inserção da modificação da técnica em 10 pacientes que realizaram reconstrução nasal total. Resultados: Após a análise dos 10 casos, utilizando a modificação da técnica inserida no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre, encontramos uma melhoria da forma do nariz, a válvula nasal interna com preservação da função e sem sequelas secundárias à retirada do enxerto auricular. Conclusão: Nesta série de casos, a modificação da técnica de Max Pereira resultou em tratamento estético funcional adequado quando implementada no protocolo de reconstrução nasal total do Hospital de Clínicas de Porto Alegre, sem aumentar a morbidade na área doadora.


Introduction: Nasal reconstruction is the oldest plastic surgery technique. The nasal anatomy is complex and requires an association of techniques for the restoration of function and adequate nasal esthetics. Pereira et al. described a technique that allows total nasal reconstruction of the alar cartilage through the use of an auricular cartilage graft, with minimal deformity secondary to the donor site. The objective of the present study is to present a modification, by Collares et al., of the technique described above, which allows the reconstruction of another anatomical region of the nose without increasing morbidity, and its insertion into the total nasal reconstruction protocol of Hospital de Clínicas of Porto Alegre. Methods: A retrospective study was conducted. We evaluated technique modification in 10 patients who underwent total nasal reconstructions. Results: After examining the 10 patients who were treated with the modified total nasal reconstruction protocol at the Hospital de Clínicas of Porto Alegre, we observed an improvement in the nose shape and internal nasal valve with preservation of function, without sequelae secondary to auricular graft removal. Conclusion: In this case series, the modification of the Max Pereira technique resulted in adequate aestheticfunctional treatment when implemented in the total nasal reconstruction protocol of the Hospital de Clínicas of Porto Alegre, without increasing the morbidity in the donor area.

ABSTRACT

INTRODUÇÃO: Os implantes mamários continuam sendo uma opção muito popular tanto para pacientes de cirurgia plástica estética quanto reconstrutora. Existem múltiplos fatores que podem afetar os resultados de cirurgias com implante mamário. Um adequado planejamento sobre o posicionamento da incisão, necessidade de associar mastopexia, plano de inserção e modelo do implante aumentam a probabilidade de resultados adequados e minimizam a necessidade de tratamento cirúrgico secundário. Estudo realizado para descrever a experiência do serviço de Cirurgia Plástica do Hospital de Clínicas de Porto Alegre entre 2011 e 2016 correlacionando o planejamento cirúrgico realizado com as taxas de complicações e reintervenção cirúrgica. MÉTODOS: Coorte retrospectiva que analisou os pacientes submetidos a implantes mamários no Hospital de Clínicas de Porto Alegre entre 2011 e 2016, sendo incluídos somente casos de mamoplastia de aumento estética, associada ou não à mastopexia. Todos os pacientes tiveram seu prontuário analisado; posteriormente, realizou-se uma ligação telefônica para complementar as informações do questionário. Finalizou-se com uma consulta com um cirurgião plástico do serviço, que examinou a paciente e confirmou os dados coletados para o questionário, não sendo em nenhum caso o cirurgião assistente. RESULTADOS: Não há diferença significativa entre a variação no planejamento cirúrgico e a incidência de complicações. CONCLUSÃO: Ainda não há consenso quanto à melhor via de acesso e plano do implante mamário, sendo necessários estudos comparando as diferentes rotinas de cada serviço. No momento os melhores resultados ainda são baseados numa rotina sistematizada, dissecção cirúrgica precisa e contaminação mínima.


INTRODUCTION: Breast implants remain a very popular option both for aesthetic and reconstructive plastic surgeries. A number of factors can affect the results of breast implant surgeries. The adequate planning on incision placement, need to associate mastopexy, insertion plane, and implant model increase the likelihood of adequate outcomes and reduce the need for secondary surgical treatment. This study describes the experience of a Plastic Surgery Service at the Hospital de Clínicas de Porto Alegre from 2011 to 2016 by correlating surgical planning with complication rates and surgical reintervention. METHODS: A retrospective cohort that analyzed patients who underwent breast implants at the Hospital de Clínicas de Porto Alegre between 2011 and 2016, and included only cases of aesthetic breast augmentation, associated or not with mastopexy. All patients had their records analyzed, and after that an interview by phone was conducted to complement the information of the questionnaire. The analyzed was concluded with an appointment with a plastic surgeon of the service who examined the patient and confirmed the data collected for the questionnaire. No patients was evaluated by the assistant surgeon in last examination. RESULTS: There was no significant difference between variation in surgical planning and incidence of complications. CONCLUSION: Still, no consensus exists regarding the best access route and plan for the breast implant. Further studies are necessary to compare the different routines of each service. Currently, best results are still based on routine systematization, precise surgical dissection and minimal contamination.

ABSTRACT

Descrita no século XIX, a deformidade auricular de Stahl consiste em uma má formação auricular rara, caracterizada por hipoplasia da raiz da anti-hélice com o alargamento de sua base e uma terceira raiz da anti-hélice conectando-a à parte posterior da hélice, deformando a porção posterossuperior do pavilhão auditivo. A correção cirúrgica é o tratamento definitivo, porém, pela diversidade de apresentações clínicas, não há uma técnica padrão para todos os casos. O método descrito neste relato é mais uma opção de tratamento e consiste na ressecção da terceira cruz e confecção da raiz superior da anti-hélice.


Stahl's ear deformity was first described in the 19th century and it consists of a rare auricular deformity characterized by hypoplasia of the antihelix crus with enlargement of its base and a third crus of the antihelix connected to posterior portion of helix crus, which deforms the posterolateral wall of the external auditory canal. Reconstructive surgery is the definitive treatment, however, because of the diversity of clinical presentations, no standard technique exist for all cases. The method described in this report is another treatment option and entails the resection of the third crus and reconstruction of superior crus of the antihelix.
