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

■ RESUMO Os defeitos na região palpebral são causados principalmente por excisões cirúrgicas de neoplasias cutâneas. Os objetivos da reconstrução palpebral estão fundamentados na restauração da funcionalidade desta unidade anatômica para manter a proteção ocular e a recuperação de uma aparência normal devido à importância crítica da região periocular na estética facial. O reparo dos defeitos palpebrais começa com uma cuidadosa avaliação dos componentes anatômicos que têm sido ressecados e precisam ser reconstruídos; a extensão e a localização do defeito guiarão a reconstrução. Grandes defeitos comprometendo a totalidade da espessura palpebral são um desafio para os cirurgiões plásticos. Milhares de técnicas cirúrgicas têm sido descritas para a reconstrução de defeitos palpebrais de espessura total; apresentamos neste artigo a descrição de um caso de reconstrução dinâmica da pálpebra com associação de um retalho frontal com transposição do músculo temporal após ressecção de um carcinoma basocelular infiltrativo recidivado.


■ ABSTRACT Surgical excisions of skin neoplasms mainly cause defects in the eyelid region. The objectives of eyelid reconstruction are based on the restoration of this anatomical unit's functionality to maintain eye protection and recovery from a normal appearance due to the critical importance of the periocular region in facial aesthetics. Repair of eyelid defects begins with a careful evaluation of the anatomical components that have been resected and need to be reconstructed; the extent and location of the defect will guide the reconstruction. Large defects compromising the entire body thickness are a challenge for plastic surgeons. Thousands of surgical techniques have been described for the reconstruction of total thickness eyelid defects; we present in this article the description of a case of dynamic eyelid reconstruction with an association of a frontal flap with temporal muscle transposition after resection of a recurrent infiltrative basal cell carcinoma.

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

Introdução: A abdominoplastia é um procedimento com índice considerável de complicações, ainda que, em sua maioria, de bom prognóstico. Algumas complicações, entretanto, podem ser catastróficas, como a necrose extensa de pele e as complicações infecciosas graves. Dentre as causas incomuns de perda extensa de pele no pós-operatório, podemos citar o pioderma gangrenoso (PG), doença de curso crônico, recidivante, com comportamento imprevisível e de etiologia ainda desconhecida. No âmbito da cirurgia plástica, essa doença pode mimetizar clinicamente complicações pós-operatórias isquêmicas ou infecciosas, cujos tratamentos diferem por completo do tratamento do PG. Relato de Caso: Paciente feminina, 41 anos, previamente hígida, foi submetida à abdominoplastia associada à lipoaspiração e mamoplastia de aumento com colocação de próteses mamárias. Evoluiu com edema, calor hiperemia e dor em incisão de abdominoplastia, além de comprometimento clínico sistêmico. Submetida a desbridamentos cirúrgicos e tratamento sistêmico, com piora progressiva das lesões. Diante do insucesso dos tratamentos propostos, aventada a hipótese diagnóstica de pioderma gangrenoso. Conclusão: O PG, apesar de raro, deve ser aventado como diagnóstico diferencial em casos de complicações pós-operatórias com perda e necrose de pele que não respondem às medidas iniciais de tratamento, além de quadros aparentemente infecciosos que não respondem às terapias antibióticas adotadas.


Introduction: Abdominoplasty is a procedure with a considerable rate of complications, even though, for the most part, it has a good prognosis. Some complications, however, can be catastrophic, such as extensive skin necrosis and serious infectious complications. Among the unusual causes of extensive skin loss in the postoperative period, we can mention gangrenous pyoderma (PG), a chronic, recurrent disease with unpredictable behavior and an unknown etiology. In the field of plastic surgery, this disease can clinically mimic ischemic or infectious postoperative complications, whose treatments differ completely from the treatment of PG. Case Report: A 41-year-old female patient, previously healthy, underwent abdominoplasty associated with liposuction and breast augmentation with the placement of breast implants. The patient evolved with edema, hyperemia and pain in an abdominoplasty incision, in addition to systemic clinical involvement. She was submitted to surgical debridement and systemic treatment, with progressive worsening of the lesions. In view of the failure of the proposed treatments, the diagnostic hypothesis of gangrenous pyoderma was raised. Conclusion: PG, although rare, should be considered as a differential diagnosis in cases of postoperative complications with skin loss and necrosis that do not respond to initial treatment measures, in addition to apparently infectious conditions that do not respond to adopted antibiotic therapies.

ABSTRACT

Introdução: A prevalência de malformações da orelha chega a 5% quando considerada toda a população mundial. Primariamente descrita em 1975 a orelha constricta representa um grupo de deformidades envolvendo o terço superior da cartilagem auricular com características em comum. O impacto estético e o estigma social dessas deformidades podem levar a danos psicológicos ao paciente quando não corrigidos. Métodos: Descrevemos a seguir a técnica utilizada no serviço de cirurgia plástica do Hospital de Clínicas de Porto Alegre. Resultados: O resultado pode ser evidenciado com 30 dias de pós-operatório. Conclusão: O método descrito, de reacomodação da cartilagem, é uma opção para o tratamento dessa deformidade com adequado resultado estético.


Introduction: The prevalence of ear malformations reaches 5% when considering the entire world population. Primarily presented in 1975, the constricted ear represents a group of deformities of the upper third of the auricular cartilage with common features. The aesthetic impact and social stigma of these deformities can cause psychological harm to the patient when not corrected. Methods: We describe below the technique used in the plastic surgery department of the Hospital de Clínicas de Porto Alegre. Results: Result can be evidenced with 30 days postoperatively. Conclusion: The described method, cartilage resettlement, is an option for treatment of this deformity with adequate aesthetic result.

ABSTRACT

Abstract Purpose: This study assessed the regeneration potential of mesenchymal stem cells (MSC) from adipose tissue associated with platelet-rich plasma (PRP) in bone regeneration. Methods: Thirty Wistar rats (Rattus norvegicus albinos) were divided into five groups (according to the grafting material and time to euthanasia): (1) autograft - 14 days (control), (2) autograft - 28 days (control), (3) MSC + PRP - 14 days, (4) MSC + PRP + papaverine - 14 days and (5) MSC + PRP + papaverine - 28 days. After euthanasia, the graft was removed and histological slides were prepared. They were assessed by a blinded pathologist using a previously published histological scale as parameter. Results: There was some degree of neoformed bone trabeculae (NBT) in 93.3% of the samples, as well as osteoblastic activity (OA). The autograft groups (14 and 28 days) had higher levels in the formation of bone trabeculae. Nonparametric data were analyzed using the Wilcoxon-Mann-Whitney test and proved not to be statistically significant at p < 0.05. Conclusions: Experimental parietal bone reconstruction, combining MSC, PRP and papaverine presented regeneration in all groups with no significant difference among them.

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

Abstract Purpose To evaluate the use of adipose-derived stem cells (ADSC) in reducing the necrosis area in an experimental model of cutaneous ischemic flap in rats submitted to subcutaneous nicotine injection to simulate a smoker patient. Methods In an experimental study, 30 rats were enrolled and divided into two experimental groups of 15 animals all submitted to a subcutaneous nicotine injection to create ischemic cutaneous flaps on their backs. Other 10 animals were used only to obtain adipose tissue derived stem cells (ADSC). The first group (n=15) received ADSC treatment at the end of surgery while the other group, the control (n=15), received no other interventions. After euthanasia, a decal was performed on the whole area of the flap, accurately defining the transition from necrosis to healthy region. Photos of all animals were collected and evaluated by scales standardized by Paint-Autocad- 2015 software to define the area of flap necrosis in each rat. Student T test was performed to compare the groups, considering a p< 0.05 significant. Data were analyzed using SPSS IBM® 18 version. Results Through the analysis of the images by the program Paint-Autocad-2015 and the area of decal obtained by the transparent sheet, we obtained a mean of 46% necrosis of the total area of the flap in the treatment group and 69.4% in the control group. In the descriptive analysis, a mean of 3.7 cm of necrosis CI 95% (3.2 - 4.2) was evident in the treatment group whereas a mean value of 5.56 CI 95% (5.2 - 5.9) was found in control group, with p value <0.001 for this comparison. Conclusion The application of adipose-derived stem cells reduces the percentage of necrosis in an experimental model of randomized cutaneous flap in rats submitted to subcutaneous nicotine injection.

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: A fissura labiopalatina é a malformação mais frequente da região da cabeça e afeta mais de 10 milhões de pessoas no mundo. O objetivo do estudo foi avaliar a autoestima em pacientes portadores de fissura labiopalatina em acompanhamento no Serviço de Cirurgia Plástica Craniomaxilofacial do Hospital de Clínicas de Porto Alegre, comparando-os com indivíduos não fissurados. Métodos: Estudo transversal contemporâneo, com 160 participantes, sendo 80 pacientes com fissura labiopalatina já submetidos a procedimentos cirúrgicos relacionados à afecção e, como grupo controle, 80 alunos e funcionários da rede pública de ensino. Um questionário para caracterizar o grupo e a escala de autoestima de Rosenberg foram utilizados para a coleta de dados. Resultados: Houve diferença significativa entre os grupos quanto ao estado civil, escolaridade e repetência escolar. Os pacientes com fissura labiopalatina apresentam níveis de autoestima menores em relação a indivíduos não afetados. Dentre eles, os subgrupos dos indivíduos com fissura bilateral, fissura completa, do gênero feminino, classe econômica D/E, baixa escolaridade, situação familiar reconstituída na infância e com resultados não satisfatórios em relação à comunicação, dentição e cicatriz de lábio também mostraram níveis de autoestima menores. Conclusão: Houve relação significativa entre fissura labiopalatina e baixa autoestima.


Introduction: Cleft lip and palate is the most frequent malformation of the head region and affects more than 10 million people worldwide. This study aims at evaluating the selfesteem in patients with cleft lip and palate and comparing that with the self-esteem of non-affected individuals during followup at the Department of Craniomaxillofacial Plastic Surgery of the Hospital de Clínicas of Porto Alegre. Methods: This is a cross-sectional, contemporary study with 160 participants, comprising 80 patients with cleft lip and palate who have already undergone surgical procedures for correcting the condition and 80 non-affected students and employees of the publicschool system as a control group. We used a questionnaire to characterize the group and the Rosenberg self-esteem scale for data collection. Results: There was a significant difference between groups in terms of marital status, schooling, and school retention. Patients with a cleft lip and palate had lower levels of self-esteem than non-affected individuals. Among them, the individuals with bilateral clefts or complete clefts; female gender; economic strata of D/E; low level of schooling; families reconstituted during childhood; and with unsatisfactory results concerning communication, dentition, and lip scar also showed lower levels of self-esteem. Conclusion: There was a significant relationship between cleft lip and palate and low self-esteem.

ABSTRACT

ABSTRACT Objective: to validate an experimental model for the measurement of glycemic levels in surgical flaps with the use of common glucometers, and to analyze the diagnostic criteria for hypoperfusion of such flaps. Methods: we performed vertical myocutaneous rectus abdominis flaps with upper pedicles bilaterally in 20 male Wistar rats, divided into two groups: with and without venous occlusion of the pedicle. We measured glucose levels in the flaps and in the systemic circulation with standard glucometers. We tested the accuracy of alternative diagnostic criteria for the detection of hypoperfusion. Results: from 15 minutes of venous occlusion on, there was a significant reduction in glucose levels measured in the congested flap (p<0.001). Using a minimum difference of 20mg/dl in the glycemic levels between the flap and systemic blood, 30 minutes after occlusion, as a diagnostic criterion, the sensitivity was 100% (95% CI 83.99-100%) and specificity of 90% (95% CI 69.90-97.21%) for the diagnosis of flap congestion. Conclusion: It is possible to measure glucose levels in vertical myocutaneous rectus abdominis flaps of Wistar rats, perfused or congested, using a common glucometer. The diagnostic criteria that compare the glucose levels in the flaps with the systemic ones were more accurate in the evaluation of tissue perfusion.


RESUMO Objetivo: validar um modelo experimental para mensuração de níveis glicêmicos em retalhos cirúrgicos com a utilização de glicosímetros comuns, e analisar os critérios diagnósticos para hipoperfusão destes retalhos. Métodos: foram realizados retalhos miocutâneos verticais de reto abdominal com pedículos superiores, bilateralmente, em 20 ratos Wistar machos, divididos em dois grupos: com e sem oclusão venosa do pedículo. Os níveis de glicose foram mensurados nos retalhos e na circulação sistêmica com glicosímetros comuns. A acurácia de critérios diagnósticos alternativos foi testada para a detecção de hipoperfusão. Resultados: a partir de 15 minutos de oclusão venosa, houve uma redução significativa dos níveis de glicose medidos no retalho congesto (p<0,001). Utilizando como critério diagnóstico uma diferença mínima de 20mg/dl nos níveis glicêmicos do retalho e do sangue sistêmico, 30 minutos após a oclusão, a sensibilidade foi de 100% (intervalo de confiança de 95% - 83,99 a 100%) e especificidade de 90% (intervalo de confiança de 95% - 69,90 a 97,21%) para o diagnóstico de congestão do retalho. Conclusão: os resultados demonstraram que é possível medir níveis de glicose em retalhos miocutâneos verticais de reto abdominal de ratos Wistar, perfundidos ou congestos, utilizando um glicosímetro comum. Os critérios diagnósticos que comparam os níveis de glicose nos retalhos com os níveis sistêmicos foram mais precisos na avaliação da perfusão tecidual.

ABSTRACT

Aim: The aim of this study was to estimate the prevalence of internal derangements (ID) of temporomandibular joint (TMJ) in patients with cleft-lip/palate. Also, to evaluate the correlation of diagnosis between Research Diagnostic Criteria for temporomandibular disorders (RDC/TMD) clinical examination and Magnetic resonance imaging (MRI). Methods: Twenty patients with cleft-lip/palate, were clinically evaluated by RDC/TMD and by MRI. The ID of TMJ evaluate were disc displacement with reduction (DDWR) and disc displacement without reduction (DDWOR). Results: The present study showed that 9 (45%) of the patients were diagnosed with ID of TMJ (8 [40%] patients with DDWR and 1 [5%] with DDWOR) and 11 (55%) present no disorders, by RDC/TMD. MRI examination revealed that 15 (75%) of the patients had ID of TMJ (13 [65%] patients with DDWR and 2 [10%] with DDWOR) and 5 (25%) present no disorders. The Kappa index between the clinical and imaging diagnosis was 0.01. Conclusion: In the present study, DDWR was diagnosed in 40-65% by the RDC/TMD and MRI, respectively; DDWOR was diagnosed in 5-10% by the RDC/TMD and MRI, respectively. The diagnostic correlation between the clinical examination based on RDC and on MRI was weak

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.

ABSTRACT

Introduction Velopharyngeal sphincter is a portion of the muscle of the palatopharyngeal arch that is capable of separating the oral cavity from the nasal cavity. It has not been determined yet whether voice intensity has an influence on this capacity. Velopharyngeal sphincter closure is accomplished by elevating and retracting the soft palate at the same time as the nasopharyngeal walls are constricted. Objective This study aims to correlate voice intensity with velopharyngeal sphincter closure in individuals without velopharyngeal dysfunction and patients with cleft lip and palate. Methods We conducted a cross-sectional, comparative, and contemporary study. The sample consisted of 16 individuals in the control group and 16 individuals in the study group. Patients underwent instrumental assessment, which we subsequently analyzed using a computer program, and a brief medical history review. The mean age of the control group was 27.6 years, whereas the mean age of the case group was 15.6 years. Results Cases showed higher voice intensity in regular and weak fricative sentences when compared with controls. There was no agreement on the analysis of the instrumental assessment between the assessors and the computer program. Regardless of voice intensity, the computer program demonstrated a similar closure pattern. Conclusion The computer program showed similar closure pattern for the three levels of intensity. There was no agreement between the three assessors and the closure pattern determined by the computer program. There was no statistically significant correlation between voice intensity and degree of velopharyngeal sphincter closure.

ABSTRACT

INTRODUÇÃO: A avaliação de cicatrizes é uma ferramenta útil na análise de intervenções cirúrgicas e outros tratamentos, ao documentar sua eficácia e possibilitar avanços. Não há registro de escala padrão em português para avaliação de cicatrizes, e a Patient and Observer Scar Assessment Scale (POSAS) foi escolhida para tradução e validação por ter recebido as melhores avaliações em revisões e por contemplar também a percepção do paciente. MÉTODOS: Foi realizada a tradução da escala POSAS do inglês para o português. A tradução foi baseada em orientações da Organização Mundial da Saúde com permissão do autor principal da escala original. Antes de realizar o pré-teste, a escala traduzida foi enviada aos autores da escala original para análise, e ajustes foram realizados. RESULTADOS: A versão para pré-teste foi aplicada por três examinadores em cinco pacientes cada (n = 15), e dificuldades foram relatadas aos autores. Nenhuma alteração foi necessária durante o pré-teste. CONCLUSÃO: Apresentamos neste artigo o processo de tradução da POSAS, e sua validação está em andamento.


INTRODUCTION: The scar assessment is a useful tool in surgical intervention and other treatments by documenting efficacy and making possible to improve them. There is no record of a standard scale in Portuguese to scar evaluation, and the Patient and Observer Scar Assessment Scale (POSAS) was chosen to translation and validation for having received the best evaluations in reviews, and because it contemplates the patients' perception. METHODS:We translated the POSAS scale from English to Portuguese. The translation was based on orientations from the World Health Organization, with permission from the main author of the original scale. Before the pre-testing, the translated scale was sent to the authors of the original scale for analysis, and adjusts were made. RESULTS: The pre-testing version was applied by three examiners in five patients each (n = 15), and difficulties were reported to the authors. No alterations were necessary during the pre-test. CONCLUSION: In this manuscript, we present the translation process of POSAS, and its validation is now in progress.

ABSTRACT

INTRODUÇÃO: A técnica de Bernard modificada por Webster é considerada por diversos autores a primeira escolha para reconstrução total de lábio inferior. Ela preserva as linhas e pontos de referência estética da face, e proporciona boa sensibilidade no lábio reconstruído, permitindo alcançar resultados estéticos e funcionais satisfatórios. Apesar de concordar com os princípios da técnica de Webster, uma modificação é proposta visando aperfeiçoar a reconstrução do vermelhão, usando retalhos nasogenianos bilaterais associados aos retalhos de avançamento originais. MÉTODOS: São apresentados cinco casos operados pelo autor no período de 2003 a 2008, e os resultados são discutidos. RESULTADOS: Demonstrou-se que a dissecção necessária para avançar os retalhos da bochecha na técnica de Bernard-Webster não inviabiliza os retalhos nasogenianos, e estes podem ser rotados adequadamente para acrescentar pele e volume ao vermelhão reconstruído. CONCLUSÃO: A modificação proposta não impõe risco aumentado ou prejuízo sobre a técnica original, e mantém ou aumenta a sua capacidade reconstrutiva.


INTRODUCTION: Many authors consider the Bernard technique modified by Webster the first choice for total lower lip reconstruction. This technique preserves skin folds and anatomical landmarks on the face, and interferes minimally with the tactile sensibility of the reconstructed lip, resulting in satisfying cosmetic and functional outcomes. Despite agreeing with the principles of the Webster technique, a modification is proposed to improve reconstruction of vermilion, by using bilateral nasolabial flaps associated with the original advancement flaps. METHODS: We report five surgical cases carried out between 2003 and 2008, and discussion of results. RESULTS: Dissection need to advance flaps in Bernard-Webster technique does not make nasolabial flaps unviable, and they can be rotated properly to add volume and skin to the reconstructed vermilion. CONCLUSION: Proposed modification of Bernard-Webster technique does not increase risk or damage compared with classic technique, and it maintains the same reconstructive capabilities or even enhances it.

ABSTRACT

Os autores apresentam uma revisão sobre reconstrução mandibular com retalho livre de fíbula, acrescida à experiência de centros de referência em reconstrução oncológica e craniofacial. A fíbula apresenta vários aspectos positivos para ser empregada como opção de reconstrução mandibular. O seu pedículo vascular, de anatomia relativamente constante, possui dois sistemas de vascularização (periosteal e endosteal), permite moldagem e montagem versáteis, pode ser acompanhada de ilha de pele para reconstrução tanto intra como extraoral, suporta implantes osteointegrados para a reconstrução da arcada dentária e tem morbidade relativamente baixa na área doadora. O retalho livre de fíbula continua sendo o padrão-ouro para a reconstrução de grandes perdas mandibulares (AU)


The authors present a review of mandibular reconstruction with free fibula flap, as well as the experience of reference centers in oncological and craniofacial reconstruction. The fibula has numerous positive aspects to be used as a mandibular reconstruction option. Its vascular pedicle, with a relatively constant anatomy, has two vascularization systems (periosteal and endosteal), allows versatile molding and assembly, can be accompanied by skin island for both intra and extraoral reconstruction, supports osseointegrated implants for reconstruction of the dental arch, and has fairly low morbidity at the donor site. The free fibula flap remains the gold standard for the reconstruction of large mandibular losses (AU)

ABSTRACT

The authors present an unusual case of a 3-year-old girl who was diagnosed with a fast-growing brachial aneurysm due to tuberous sclerosis. The patient underwent aneurysm resection and microsurgical reconstruction with reversed greater saphenous vein graft at the same time. She had a favorable outcome, without neuromuscular deficits. Doppler ultrasonography was performed for diagnosis, vein graft selection, and postoperative follow-up. The authors believe that such combined approach may be the routine for pediatric vascular reconstructions. Finally, this reconstruction has been rarely reported in tuberous sclerosis patients...

ABSTRACT

PURPOSE: To evaluate experimental cranial vault reconstructions, by combining bone morphogenetic protein type 2 (BMP-2) and different matrices. METHODS: Fourty-nine animals were initially included (seven per group). We designed an experimental, open, prospective and comparative study, divided in seven groups: 1 - BMP-2+calcium phosphate (BT); 2 - BMP-2+acellular dermal matrix (BM); 3 - BMP-2+calcium alginate (BA); 4 - TCP; 5 - MDM; 6 - ALG; 7 - Bone autograft (BAG). A bone failure was created in left parietal bone of adult male mice. At the same procedure reconstruction was performed. After five weeks, animals were sacrificed, and reconstruction area was removed to histological analysis. After exclusion due to death or infection, thirty-eight animals were evaluated (BT=5; BM=6; BA=6; TCP=7; MDM=3; ALG=6; BAG=5). RESULTS: A higher incidence of infection has occurred in MDM group (57%, P=0.037). In cortical fusion, groups BAG, TCP, and BMP-2+TCP (BT) obtained the best scores, comparing to the others (P=0.00846). In new bone formation, groups BT, BAG, and TCP have presented the best scores (P=0.00835). When neovascularization was considered, best groups were BMP-2+MDM (BM), BMP-2+ALG (BA), TCP, and MDM (P=0.001695). BAG group was the best in bone marrow formation, followed by groups BT and TCP (P=0.008317). CONCLUSIONS: Bone morphogenetic protein type 2 increased bone regeneration in experimental skull reconstruction, especially when combined to calcium phosphate. Such association was even comparable to bone autograft, the gold-standard treatment, in some histological criteria. .
