ABSTRACT

La cirugía de los terceros molares retenidos puede ser considerada una intervención de rutina para el cirujano bucomaxilofacial. Como todo procedimien-to quirúrgico, puede presentar complicaciones intra y postoperatorias. Las más frecuentes son el dolor, edema, trismus, hemorragia y fracturas de las piezas dentarias a extraer, o de las tablas óseas. Pero tam-bién se pueden presentar otras complicaciones ines-peradas, como la impulsión o desplazamiento de la pieza dentaria a espacios anatómicos vecinos, entre los que podemos encontrar al espacio pterigomandi-bular, la celda submaxilar, el seno maxilar, el espacio infratemporal, según se trate de terceros molares retenidos inferiores o superiores. En el presente ar-tículo, se describe una situación clínica de un tercer molar superior, que fue accidentalmente impulsado a la región infratemporal, y removido en una segunda cirugía realizada 3 semanas después del primer in-tento de exodoncia. Se analizan también los estudios preoperatorios para su correcto diagnóstico, y las maniobras clínicas e instrumentales tendientes a po-sibilitar su remoción minimizando las complicaciones intra y postquirúrgicas (AU)


Surgery of retained third molars can be considered a routine intervention for the oral surgeon. Like any surgical procedure, it can present intra and posto-perative complications. The most frequent are pain, edema, trismus, hemorrhage and fractures of the teeth to be extracted or of the bone tables. But other unexpected complications can also occur, such as the impulsion or displacement of the tooth to neighbo-ring anatomical spaces, among which we can find the pterygomandibular space, the submaxillary cell, the maxillary sinus, the buccal space, the infratemporal space and the lateral pharyngeal space, depending on whether they are lower or upper retained third mo-lars. In this article, the clinical case of a third upper molar is described, which was accidentally driven to the infratemporal region, which was removed in a second surgery performed 3 weeks after the first attempt at exodontics. It should be noted the impor-tance of diagnostic imaging as an indispensable com-plement to the correct location of the displaced tooth and its subsequent removal (AU)

ABSTRACT

Objetivo: Describir en un caso clínico una nueva técni- ca para la localización y la remoción de agujas fracturadas du- rante la anestesia odontológica mediante planificación virtual. Caso clínico: Una paciente de género femenino de 52 años de edad concurre a la Cátedra de Cirugía y Traumatolo- gía Bucomaxilofacial I de la Facultad de Odontología de la Universidad de Buenos Aires y relata que dos meses atrás, durante la atención odontológica, se produjo la fractura de la aguja durante la anestesia troncular mandibular. Se realiza diagnóstico y planificación virtual para conocer la ubicación exacta de la aguja y se confecciona un modelo estereolito- gráfico y una guía quirúrgica individualizada para removerla. El uso de una guía quirúrgica individualizada y confeccio- nada mediante planificación virtual permitió ubicar la aguja tridimensionalmente y con mayor precisión en espacios pro- fundos y disminuir tiempos operatorios (AU)


Aim: To describe in a clinical case a new virtual plan- ning technique for locating and removing a fractured dental anesthetic needle. Clinical case: A 52-year-old patient visited the De- partment of Oral and Maxillofacial Surgery I (School of Dentistry, University of Buenos Aires) with a retained den- tal needle in the pterygomandibular space. The needle had fractured during inferior alveolar nerve block two months previously. Virtual diagnosis and planning were performed to locate the needle and a stereolithographic model and a customized surgical guide were prepared. The use of cus- tomized surgical guides prepared by virtual planning ena- bled precise location of the dental needle in deep spaces and reduced operating times (AU)

ABSTRACT

RESUMEN Introducción: la propia asistencia médica provoca, en determinadas situaciones, problemas de salud que pueden llegar a ser importantes para el enfermo. El análisis de la mortalidad es uno de los parámetros utilizados para investigar la seguridad en la realización de procederes de cirugía mayor. Objetivo: determinar los factores asociados a la mortalidad operatoria en cirugías mayores. Materiales y métodos: se realizó un estudio observacional, descriptivo y retrospectivo, de los pacientes que fallecieron tras la realización de una cirugía mayor, en el Hospital Militar Docente Dr. Mario Muñoz Monroy, de Matanzas, en el período comprendido de enero de 2011 a diciembre de 2019. Resultados: la tercera edad aportó 77,3 % de los fallecidos. La hipertensión arterial, diabetes mellitus y cardiopatía isquémica fueron las principales comorbilidades. El abdomen agudo fue el diagnóstico operatorio más frecuente con 98 (58,3 %). Las complicaciones aportaron el 11,9 % de los fallecidos; los eventos adversos, 29,7 %, y por el curso natural de la enfermedad, murió un 58,3 %. El síndrome de disfunción múltiple de órganos y el shock séptico resultaron las principales causas de muerte (62 %). Conclusiones: la mortalidad operatoria estuvo asociada a factores de riesgo como edad avanzada, enfermedades crónicas y cirugía de urgencia. Los eventos adversos elevan la incidencia de mortalidad en cirugía mayor. Las infecciones son la principal causa de mortalidad operatoria (AU).


ABSTRACT Introduction: medical care itself causes, in certain situations, health problems that could be very important for the patient. The mortality analysis is one of the parameters used to study safety performing procedures of major surgery. Objective: to determine the factors associated to operatory mortality in major surgeries. Materials and methods: a retrospective, descriptive and observational study was carried out of the patients who passed away after undergoing a major surgery in the Military Hospital Dr. Mario Munoz Monroy in the period between January 2011 and December 2019. Results: 77.3 % of the deceased were elder people. The main co-morbidities were arterial hypertension, diabetes mellitus and ischemic heart disease. The most frequent surgery diagnosis was acute abdomen with 98 patients (58.3 %). Complications yielded 11.9 % of the deceases, adverse events 29.7 % and 58.3 % died due to the natural course of the disease. The organs multiple dysfunction syndrome and septic shock were the main causes of dead (62 %). Conclusions: operatory mortality was associated to risk factors like advanced age, chronic diseases and emergency surgery. The adverse events increase mortality incidence in major surgery. Infections are the main causes of operatory mortality (AU).

ABSTRACT

A hidradenite supurativa (HS) é uma doença inflamatória crônica da pele caracterizada por apresentar nodulações subcutâneas, dolorosas e com sinais flogísticos, inicialmente enrijecidas e que evoluem para consistência amolecida. Ocorre em 1 a 4% da população mundial. A sua etiologia ainda é pouco conhecida, sugere-se que aconteça devido à oclusão do ducto apócrino dos folículos pilosos por fatores precipitantes como fricção de tecido adiposo, higiene precária, entre outras. Seu diagnóstico é eminentemente clínico, pela identificação de lesões típicas recorrentes em forma de nodularidades, abcessos, tratos fistulosos ou cicatrizes. Não há testes patognomônicos. Sua evolução é variável e de difícil manejo, o qual pode ser feito com terapia tópica, sistêmica ou por exérese cirúrgica. Este trabalho revisa a avaliação por imagem da hidroadenite supurativa e demonstra imagens de um caso avaliado por ressonância magnética. A avaliação por exames de imagem, apesar de pouco específica para firmar diagnóstico, é muito útil na determinação da extensão da doença, assim como na exclusão de diagnósticos diferenciais, destacando-se o papel da ressonância magnética na avaliação das lesões anogenitais, com potencial de reduzir recorrências.


Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by painful deep-seated skin nodules with phlogistic signs, which are initially hard and progress to have a soft consistency. It occurs in 1­4% of the world population. Etiology of HS is still poorly understood and is suggested to occur due to occlusion of the apocrine duct of the hair follicles by triggering factors such as friction of the adipose tissue and poor hygiene, among others. Diagnosis is eminently clinical, through the identification of typical recurrent lesions that include nodules, abscesses, sinus tracts, or scars. There are no pathognomonic tests used to confirm its presence. Progression is variable and difficult to manage, which can be done with topical or systemic therapy or surgical excision. This work reviews the imaging assessment of HS and shows images of a case assessed by magnetic resonance imaging. Imaging assessment, although not specific enough for a diagnosis, is useful to determine the extent of the disease and to exclude differential diagnoses. Moreover, magnetic resonance imaging has an important role in the assessment of anogenital lesions and a potential to reduce recurrences.

ABSTRACT

Defeitos parciais de orelha podem ser tratados de diversas formas, dentre elas o fechamento primário, cicatrização por segunda intenção ou retalhos. Diversas opções técnicas foram descritas para a sua reconstrução de modo a manter o contorno natural da orelha, sem sacrificar tecido sadio ou alterar sua estética e função. Apresentamos neste artigo dois casos atendidos no Instituto do Câncer do Hospital de Base de São José do Rio Preto de reconstrução de defeitos condrocutâneos de orelha após ressecção de carcinoma basocelular em região central da orelha, com a confecção de retalho retroauricular ilhado transposto através de uma janela cartilaginosa e com o pedículo desepidermizado. Área doadora com fechamento primário. Tal procedimento constitui técnica segura, pois a região retroauricular é ricamente vascularizada, é de fácil execução, em único estágio e com resultado estético e funcional satisfatório.


Partial ear defects can be treated in several ways, including primary closure, healing by secondary intention, or flaps. Several surgical options have been described for reconstruction in order to maintain the natural contour of the ear, without sacrificing healthy tissues or changing the aesthetics and function. In this article, we present two cases of reconstruction of chondrocutaneous defects of the ear after resection of basal cell carcinoma in the central region of the ear, with the production of a retroauricular island flap transposed through a cartilaginous window with the de-epidermized pedicle. The donor area healed following a primary closure. This procedure can be performed in a single stage, yields satisfactory aesthetic and functional results, and is safe because the retroauricular region is richly vascularized.

ABSTRACT

Introdução: O hematoma, complicação mais frequente do face-lift, pode exigir reabordagem cirúrgica e atrasar a recuperação do paciente. Na literatura, sua incidência varia entre 0,2 e 8%, sendo fundamentais novos estudos para padronização das medidas de prevenção. O objetivo é apresentar uma proposta de sistematização perioperatória que previna eficientemente a formação de hematomas em ritidoplastias. Métodos: Foram analisados 594 prontuários de pacientes operados pelo autor entre os anos de 2011 a 2018 a fim de se comparar as incidências de hematomas anteriores e posteriores à sistematização implementada no ano de 2015. Resultados: De julho de 2011 a dezembro de 2014, antes da adoção da sistematização, houve uma incidência de hematomas de 3,43% em 233 casos. Após sua adoção, houve uma queda para 1,66% em 361 casos realizados. Os últimos 177 casos consecutivos não apresentaram a complicação. Conclusão: Observamos redução expressiva da incidência de hematomas pós-ritidoplastias após o uso da padronização proposta. Nenhuma das medidas adotadas seria eficiente isoladamente, sendo o conjunto essencial na prevenção desta grave complicação.


Introduction: Hematoma, the most frequent complication of face-lift procedures, may require a second surgical approach, which delays patient recovery. In the literature, its incidence ranges from 0.2% to 8%, and further studies are essential to standardize preventive measures. The objective is to present a proposal of perioperative systematization for effectively prevention of hematoma formation after rhytidectomies. Methods: We analyzed the medical records of 594 patients who underwent operation by the author between 2011 and 2018 to compare the incidence of hematomas before and after the systematization implemented in 2015. Results: From July 2011 to December 2014, before the adoption of the systematization, the incidence of hematomas was 3.43% in 233 cases. After its adoption, the incidence decreased to 1.66% in 361 cases. The last 177 consecutive cases did not have this complication. Conclusion: We observed a significant reduction in the incidence of hematomas following rhytidectomy after the use of the proposed standardization. None of the measures would be effective alone; thus, their combined adoption is essential in preventing this serious complication.

ABSTRACT

Bile duct injury during laparoscopy is the most important complication of laparoscopic cholecystectomy. Bile duct injuries place an enormeous burden on the health and productivity of the population. To avoid this severe complication, it has been one of the central objectives of the biliary surgery since its beginings. Traditional teaching of surgery fails in the prevention of laparoscopic bile duct injuries, and they cannot control the problem. Assessment of biliary anatomy of the bile duct injury is mandatory for prevention of iatrogenic bile duct injuries. With a proper knowledge for identification and categorization of the triangle of Calot to avoid technical errors we will achieve system changes to improve patient safety. Finally, although medical consensus and substantial evidence exist promoting the importance of the Critical Vision on Safety, with the development of a fundamental support to the regularization, a safe operative technique will decrease the rate of severe complications of the bile duct injury

ABSTRACT

Introdução: O ceratoacantoma é uma neoplasia epitelial de rápido crescimento, mais frequente em áreas de exposição solar. Habitualmente, apresenta-se como lesão única, arredondada, com depressão central preenchida de queratina. As semelhanças clínicas e histopatológicas com o carcinoma de células escamosas, frequentemente, dificultam o diagnóstico diferencial. A biópsia excisional é a abordagem de escolha, permitindo diagnóstico e tratamento. Método: O presente estudo é observacional e retrospectivo, com dados de 162 pacientes tratados de 2005 a 2013, no Hospital Felício Rocho, em Belo Horizonte, MG. Todos os pacientes submeteram-se à excisão cirúrgica dos tumores. Foram estudados: sexo, idade, número de lesões, localização, tamanho do tumor e diagnóstico pré-operatório. Resultados: Dos 162 pacientes, totalizando 173 lesões, 154 (95,06%) apresentavam ceratoacantoma único. Noventa e dois eram do gênero masculino (56,80%) e 70 do feminino (43,20%). A idade dos pacientes variou de 11 a 96 anos, com média de 71,23 anos. As lesões localizavam-se predominantemente nos membros superiores (43,64%), na face (28,48%) e nos membros inferiores (17,58%). Nas hipóteses diagnósticas formuladas pelos cirurgiões, no pedido do exame anatomopatológico, houve diagnóstico correto em 63,13%. Conclusão: O ceratoacantoma é uma neoplasia epitelial de características morfológicas semelhantes ao carcinoma de células escamosas, o que, por muitas vezes, dificulta o diagnóstico. Torna-se necessária, portanto, a excisão cirúrgica completa das lesões suspeitas para diagnóstico e tratamento corretos.


Introduction: Keratoacanthoma is an epithelial neoplasm of rapid growth, more frequent in areas of sun exposure, and usually appears as a single, rounded lesion with a central depression filled with keratin. Clinical and histopathological similarities with squamous cell carcinoma often make differential diagnosis difficult. Excisional biopsy is the approach of choice, allowing diagnosis and treatment. Method: This is an observational and retrospective study, in which data of 162 patients treated at the Hospital Felício Rocho from 2005 to 2013, in Belo Horizonte, MG, were analyzed. All patients underwent surgical excision of tumors. Data on sex, age, number of lesions, location, tumor size, and preoperative diagnosis were studied. Results: Of the 162 patients, with a total of 173 lesions, only 154 (95.06%) had keratoacanthoma. There were 92 male (56.80%) and 70 female (43.20%) patients. The age of patients ranged from 11 to 96 years, with an average of 71.23 years. The lesions were located predominantly in the upper limbs (43.64%), face (28.48%), and lower limbs (17.58%). In the diagnostic hypotheses formulated by surgeons at the request of the pathology, the diagnosis was correct in 63.13%. Conclusion: Keratoacanthoma is an epithelial tumor with morphological characteristics similar to those of squamous cell carcinoma, which often complicates the diagnosis. Therefore, the complete excision of the suspicious lesions is necessary for correct diagnosis and treatment.

ABSTRACT

Introdução: Apesar do avanço no diagnóstico e no tratamento das pacientes com neoplasia mamária, ainda há casos que se apresentam como doença localmente avançada. Nesse contexto, o controle oncológico requer ressecções extensas e complexos procedimentos reparadores. A participação do cirurgião plástico nas equipes multidisciplinares de tratamento oncológico tem apresentado importância crescente tanto nas etapas de planejamento como de execução. O objetivo é analisar prospectivamente casos de pacientes com extensas ressecções no tórax e reconstrução de parede torácica quanto aos seus resultados e complicações no período de 2014-2016. Métodos: Seguimento prospectivo por 6 meses de 15 casos de pacientes submetidas a extensas ressecções oncológicas no tórax e reconstrução por um mesmo cirurgião plástico em hospitais da rede pública de São Paulo-SP. Foram coletados os dados: idade, diagnóstico, queixa pré-operatória, extensão da área de ressecção e incidência de complicações locais. Resultados: As pacientes tinham idade média de 49,2 anos, a queixa mais comum era massa papável, o diagnóstico mais comum era neoplasia da mama (80%), a maioria das ressecções preservou o plano muscular e a área média de ressecção foi de 259,2 cm2. O retalho miocutâneo do grande dorsal em V-Y foi o mais utilizado, e o toracoabdominal foi o segundo. Epiteliólise foi detectada em 13,3% das pacientes e necrose parcial menor que 5% do retalho em 13,3%. Conclusão: Na presente casuística, as pacientes portadoras de neoplasias extensas no tórax representaram um desafio para a reconstrução local, necessitando de planejamento pré-operatório minucioso e com múltiplas opções. A participação do cirurgião plástico no tratamento desses casos contribuiu para redução de morbidade e demonstrou baixo índice de complicações.


Introduction: In spite of advances in the diagnosis and treatment of patients with breast cancer, there are still cases that present with locally advanced disease. In this context, cancer control requires extensive resections and complex repair procedures. The participation of the plastic surgeon in the multidisciplinary cancer treatment teams has been increasingly important in both the planning and execution stages. The aim of this study is to prospectively analyze patients who underwent extensive chest resections and thoracic wall reconstruction with regard to their results and complications in the period 2014-2016. Methods: Prospective 6-month follow-up of 15 patients who underwent extensive oncological resections in the chest and reconstruction by the same plastic surgeon in public hospitals of São Paulo was done. The following data were collected: age, diagnosis, preoperative complaint, extent of resection area, and incidence of local complications. Results: Patients had a mean age of 49.2 years, the most common complaint was a papillary mass, the most common diagnosis was breast cancer (80%), the most resection area preserved was the muscular plane, and the mean resection area was 259.2 cm2. The V-Y latissimus dorsi myocutaneous flap was the most used, and the thoracoabdominal flap was the second. Epitheliolysis was detected in 13.3% of the patients, and partial necrosis less than 5% of the flap in 13.3%. Conclusion: In the present study, patients with extensive cancers in the thorax presented a challenge for local reconstruction, requiring detailed preoperative planning and multiple options. The participation of the plastic surgeon in the treatment of these patients contributed to the reduction of morbidity rate and low rate of complications.

ABSTRACT

Las lesiones iatrogénicas de las vías biliares (LIVB) representan una complicación quirúrgica grave de la colecistectomía laparoscópica (CL). Ocurre frecuentemente cuando se confunde el conducto biliar con el conducto cístico; y han sido clasificados por Strasberg y Bismuth, según el grado y nivel de la lesión. Alrededor del tercio de las LIVB se reconocen durante la CL, al detectar fuga biliar. No es recomendable su reparación inmediata, especialmente cuando la lesión está próxima a la confluencia o existe inflamación asociada. El drenaje debe establecerse para controlar la fuga de bilis y prevenir la peritonitis biliar, antes de transferir al paciente a un establecimiento especializado en cirugía hepatobiliar compleja. En pacientes que no son reconocidos intraoperatoriamente, las LIVB manifiestan tardíamente fiebre postoperatoria, dolor abdominal, peritonitis o ictericia obstructiva. Si existe fuga biliar, debe hacerse una colangiografía percutánea para definir la anatomía biliar y controlar la fuga mediante stent biliar percutáneo. La reparación se realiza seis a ocho semanas después de estabilizar al paciente. Si hay obstrucción biliar, la colangiografía y drenaje biliar están indicados para controlar la sepsis antes de la reparación. El objetivo es restablecer el flujo de bilis al tracto gastrointestinal para impedir la formación de litos, estenosis, colangitis y cirrosis biliar. La hepáticoyeyunostomía con anastomosis en Y de Roux termino-lateral sin stents biliares a largo plazo, es la mejor opción para la reparación de la mayoría de las lesiones del conducto biliar común.


Iatrogenic bile duct injuries (IBDI) represent a serious surgical complication of laparoscopic cholecystectomy (LC). Often it occurs when the bile duct merges with the cystic duct; and they have been ranked by Strasberg and Bismuth, depending on the degree and level of injury. About third of IBDI recognized during LC, to detect bile leakage. No immediate repair is recommended, especially when the lesion is near the confluence or inflammation is associated. The drain should be established to control leakage of bile and prevent biliary peritonitis, before transferring the patient to a specialist in complex hepatobiliary surgery facility. In patients who are not recognized intraoperatively, the IBDI manifest late postoperative fever, abdominal pain, peritonitis or obstructive jaundice. If there is bile leak, percutaneous cholangiography should be done to define the biliary anatomy, and control leakage through percutaneous biliary stent. The repair is performed six to eight weeks after patient stabilization. If there is biliary obstruction, cholangiography and biliary drainage are indicated to control sepsis before repair. The ultimate aim is to restore the flow of bile into the gastrointestinal tract to prevent the formation of calculi, stenosis, cholangitis and biliary cirrhosis. Hepatojejunostomy with Roux-Y anastomosis termino-lateral without biliary stents long term, is the best choice for the repair of most common bile duct injury.

ABSTRACT

O Capítulo de Cirurgia do Contorno Corporal da Sociedade Brasileira de Cirurgia Plástica realizou em 2012 um amplo estudo dos parâmetros de segurança para a realização de uma lipoaspiração, antecedendo ao curso do Capítulo, realizado em 2013, no Rio de Janeiro, durante o 50º Congresso Brasileiro de Cirurgia Plástica, com a presença do ilustre Dr. Yves Gérard Illouz e grande número de participantes. Os autores realizaram uma revisão e atualização destes parâmetros, incorporando recentes avanços e sistematizando de forma prática as informações relevantes para a realização de uma lipoaspiração mais segura. Com a colaboração de anestesiologista, intensivista e cirurgião vascular, experientes no suporte ao procedimento, são apresentadas novas orientações práticas para o pré-operatório, trans e pós-operatório de uma lipoaspiração mais segura.


In 2012, the Research Group on Body Contouring Surgery of the Brazilian Society of Plastic Surgery conducted an extensive study on the safety of liposuction before the initiation of the course of the Group, held in 2013 in Rio de Janeiro during the 50th Brazilian Congress of Plastic Surgery, with the presence of the illustrious Dr. Yves Gérard Illouz and a large number of participants. The authors performed a review and update of the safety parameters, incorporating recent advances and systematizing relevant information for the execution of a safer liposuction. With the collaboration of anesthesiologist, intensive care physician, and vascular surgeon, all with extensive experience in supporting the procedure, new practical guidelines were presented for a safer liposuction on the preoperative, transoperative, and postoperative periods.

ABSTRACT

INTRODUÇÃO: A hipertrofia mamária é uma alteração do contorno corporal bastante frequente, e de grande importância clínica, já que repercute na mulher tanto psicologicamente como funcionalmente, em especial nas grandes hipertrofias. Para evitar o sofrimento vascular e necroses nos casos de mamoplastias redutoras em grandes hipertrofias e ptoses severas, uma opção segura é a realização de mamoplastia redutora a Pitanguy, associada à confecção de retalho dermoglandular areolado superomedial de Silveira Neto. MÉTODOS: Foram realizadas, no período de abril de 2014 a julho de 2016, 14 mamoplastias redutoras utilizando a técnica descrita. A ressecção de parênquima variou entre 900 gramas a 1.800 gramas, e a distância de deslocamento superior do complexo areolopapilar variou entre 5 e 15 centímetros. Observou-se a incidência de complicações vasculares e cicatriciais do complexo areolopapilar. RESULTADOS: Todas as pacientes referiram satisfação com o resultado estético e funcional obtidos pela cirurgia. Em quatro pacientes, houve pequena área de epidermólise na região de encontro do sulco submamário com a cicatriz vertical, que cicatrizaram por segunda intenção, sem causar grandes sequelas estéticas. Em nenhum dos casos houve epidermólise ou necrose parcial ou total do complexo areolopapilar, apesar de grandes ascensões dos mesmos. Houve dois casos de hipocromia em pequena área da margem areolar. CONCLUSÃO: Para o tratamento de grandes hipertrofias mamárias, a combinação das técnicas selecionadas foi bem-sucedida em possibilitar grandes reduções volumétricas, correção de ptoses severas, com elevação do complexo areolopapilar por distâncias significativas, com segurança. Desta forma, foram obtidos bons resultados estéticos e funcionais, sem sofrimentos vasculares do complexo areolopapilar.


INTRODUCTION: Mammary hypertrophy is common, and has great clinical importance, affecting women both psychologically and functionally, especially when severe. To avoid vascular compromise and necrosis associated with reduction mammoplasty in cases with severe hypertrophy and ptosis, a safe option involves combined use of Pitanguy technique and a Silveira Neto areolar superomedial dermoglandular flap. METHODS: Fourteen reduction mammoplasties were performed between April 2014 and July 2016 with the combined technique. Parenchymal resection ranged from 900 to 1,800 g, and the superior displacement distance of the nipple-areolar complex ranged from 5 to 15 cm. Vascular and scarring complications of the nipple-areolar complex were evaluated. RESULTS: All patients reported satisfaction with the aesthetic and functional results obtained with surgery. A small area of sloughing where the inframammary crease and the vertical scar intersect was observed in 4 patients; healing occurred by second intention, without significant aesthetic sequelae. Neither sloughing nor partial or total necrosis of the nipple-areolar complex were observed, despite the significant elevation. Two cases of hypopigmentation of a small area at the areolar margin were observed. CONCLUSION: The combined technique was successful in the treatment of prominent mammary hypertrophy, enabling safe reduction of large volumes, correction of severe ptosis, and significant elevation of the nipple-areolar complex. Good aesthetic and functional results were obtained, without vascular compromise of the nipple-areolar complex.

ABSTRACT

ABSTRACT Objective Correlate the middle cerebral artery bifurcation aneurysm morphology with the pre-operative and intra-operative risk of rupture. Methods Forty patients with 46 middle cerebral artery bifurcation aneurysms were treated microsurgically by the same surgeon. Aneurysms were classified according to shape and the Fisher test was applied to analyze the effect of morphology on the pre-operative and intra-operative rupture. Results Pre-operative and intra-operative ruptures were observed in 8/46 patients (17.4%) and 14/46 patients (30.4%) respectively. Thirty-two cases (69.6%) had no symptoms postoperatively, modified Rankin score (MRS) of 0; 6.5% had MRS of 1 (no significant disability); 13% had MRS of 2 (slight disability); 4.3% had moderately severe disability (MRS of 4); and there were 3 deaths (6.5%) post-operatively. The morphology was not directly related to the rupture rate. Conclusion In general, ruptures are not affected by the morphology or the studied variables. Larger series are needed to validate these outcomes.


RESUMO Objetivo Correlacionar a morfologia do aneurisma da bifurcação da artéria cerebral média com o risco de ruptura pré-operatória e intra-operatória. Métodos 40 pacientes com 46 aneurismas de bifurcação da artéria cerebral média receberam tratamento microcirúrgico pelo mesmo cirurgião. Os aneurismas foram classificados de acordo com a morfologia e o teste de Fisher foi aplicado para analisar o efeito da morfologia sobre a ruptura pré-operatória e intra-operatória. Resultados As rupturas pré e intra-operatória foram observadas em 8/46 pacientes (17,4%) e 14/46 (30,4%) respectivamente. Trinta e dois casos (69,6%) não apresentaram sintomas pós-operatórios, pontuação de Rankin modificada (MRS) de 0, 6,5% tinham MRS de 1 (sem incapacidade significativa), 13% tinham MRS de 2 (leve incapacidade), 4,3% moderadamente grave (MRS de 4) e houve 3 óbitos (6,5%) durante o pós-operatório. A morfologia não estava diretamente relacionada à taxa de ruptura pré-operatória ou intra-operatória. Conclusão Em geral, as rupturas não são afetadas pela morfologia ou pelas variáveis estudadas. São necessárias séries maiores para validar esses resultados.

ABSTRACT

ABSTRACT Optical internal urethrotomy (OIU) is the most common procedure performed for short segment bulbar urethral stricture worldwide. This procedure most commonly performed using Sachse’s cold knife. Various perioperative complications of internal urethrotomy have been described in literature including bleeding, urinary tract infection, extravasation of fluid, incontinence, impotence, and recurrence of stricture. Here we report a unique complication of breakage of Sachse knife blade intraoperatively and its endoscopic management.

ABSTRACT

ABSTRACT Background Endoscopic treatment of superficial gastrointestinal tumors is routinely performed, however the advantages and shortcomings of submucosal pressure-jet dissection is still debated. Objective - Aiming to compare this technique with conventional submucosal dissection, a study was designed in pigs. Methods - Areas of the antral mucosa of the stomach with a diameter of 2 cm2 (6 per animal) were marked, and resected by means of the hybrid-knife (experimental technique), and Flush-knife or IT-knife (controls). An ERBE ICC 300 electrosurgical unit was adopted. End-points were procedural time, complications, and quality of the resected specimen. Results - A total of 27 interventions were conducted in five animals. Time spent with the two options was quite short, and similar: 9.5±3.1 vs 8.0±3.0 minutes (P=0.21). Complications didn't differ (three per group, not significant), and removed specimen looked adequate in both circumstances. Conclusion - The hybrid-knife technique is an acceptable alternative to submucosal dissection, showing no difference compared to the standard technique taking into consideration the procedure, the presence of complications and the quality of the resected specimen.


RESUMO Contexto O tratamento endoscópico de tumores gastrointestinais superficiais é realizado rotineiramente, no entanto as vantagens e deficiências da dissecção submucosa com jato de pressão ainda é debatido. Objetivo - Visando comparar esta técnica com dissecção submucosa convencional, um estudo foi realizado em suínos. Métodos - Áreas da mucosa antral do estômago com um diâmetro de 2 cm2 (um total de 6 por animal) foram marcadas, e a ressecção através do hybrid-knife (técnica experimental), e do Flush-knife ou IT-knife (controles). Uma unidade eletro cirúrgica ERBE ICC 300 foi adotada. Os desfechos foram: tempo do procedimento, complicações e qualidade da amostra ressecada. Resultados - Um total de 27 intervenções foram realizadas em cinco animais. O tempo gasto com as duas técnicas foi curto e semelhante: 9,5±3,1 vs 8,0±3,0 minutos (P=0,21). As complicações não diferiram (três por grupo, não significativas), e amostras retiradas foram adequadas em ambas as circunstâncias. Conclusão - A técnica de hybrid-knife é uma alternativa aceitável para dissecção submucosa, demonstrando não haver diferença em comparação à técnica convencional levando em consideração o tempo de procedimento, a presença de complicações e a qualidade da amostra ressecada.

ABSTRACT

ABSTRACT CONTEXT: Hardware breakage during hip surgery can pose challenging and difficult problems for orthopedic surgeons. Apart from technical difficulties relating to retrieval of the broken hardware, complications such as adjacent joint arthritis and damage to neurovascular structures and major viscera can occur. Complications occurring during the perioperative period must be informed to the patient and proper documentation is essential. The treatment options must be discussed with the patient and relatives and the implant company must be informed about this untoward incident. CASE REPORT: We report a case of complete removal of the implant and then removal of the broken guidewire using a combination of techniques, including a cannulated drill bit, pituitary forceps and Kerrison rongeur. CONCLUSIONS: We suggest some treatment options and recommendations for preventing an avoidable surgical catastrophe.


RESUMO CONTEXTO: Ruptura de material de síntese durante a cirurgia de quadril pode representar problemas desafiadores e difíceis para cirurgiões ortopédicos. Além de dificuldades técnicas com recuperação do material quebrado, complicações como artrite na articulação adjacente, danos às estruturas neurovasculares e às principais vísceras podem ocorrer. A complicação durante o período perioperatório deve ser informada ao paciente e documentação apropriada é essencial. As opções de tratamento devem ser discutidas com o paciente e seus familiares e a empresa do implante deve ser informada sobre este incidente desagradável. RELATO DE CASO: Nós relatamos um caso da remoção completa do implante e, em seguida, a remoção do fio-guia quebrado usando uma combinação de técnicas, incluindo uma broca canulada, fórceps da hipófise e rongeur de Kerrison. CONCLUSÕES: Sugerimos algumas opções de tratamento e recomendações para prevenir uma evitável catástrofe cirúrgica.

ABSTRACT

Los instrumentos metálicos utilizados en las múltiples disciplinas de la odontología están sujetos a un desgaste considerable durante su vida de uso y pueden llegar a fracturarse. La remoción de los instrumentos fracturados puede ser un evento simple, siempre y cuando su localización sea visible y accesible, pero no siempre es el caso. Desde la introducción de las agujas dentales desechables, a inicios de los 1960, la frecuencia de ruptura d e éstas ha sido mínima. Hoy en día, la fractura de estos instrumentos se debe más a la falla de las técnicas de infiltración del operador y a la carencia de medidas preventivas. Es de interés mencionar la experiencia obtenida en el caso de una paciente femenina de 25 años de edad, a quien durante un procedimiento odontológico de rutina se le alojó la totalidad de una aguja dental en el espacio pterigomandibular. Es prudente recordar la sintomatología específi ca a estos casos, los métodos de diagnósticos antiguos y de nueva generación, y el difícil manejo quirúrgico para el retiro de cuerpos extraños tan peligrosos en una localización anatómicamente compleja.


The metallic objects used in the different disciplines of today’s dentistry are subject to considerable wear during the course of their useful life and can eventually fracture. Removing these foreign objects can be a simple procedure, provided they remain visible and easy to reach. However, this is not always the case. Since the introduction of disposable dental needles in the 1960s, the incidence of instrument fracture has been minimal and today, when this does occur, it is usually due to poor infi ltration techniques on the part of the user and a lack of appropriate preventive measures. We present the interesting case of a 25-year-old female patient who underwent a dental procedure during which a com-plete dental needle became lodged in the pterygomandibular space. In cases such as this, it is important to remember the specifi c symptoms, the differences in old- and new-school diagnosis methods, and the level of diffi culty involved in surgically removing dangerous foreign objects from an anatomically complex location.

ABSTRACT

INTRODUÇÃO: O dorso nasal é um local comum para o desenvolvimento de neoplasias cutâneas, predominantemente o epitelioma basocelular. Em 1964, Barsky preconiza um retalho quadrangular do dorso nasal, com base na região glabelar, utilizando somente pele da região dorsal. Baseava-se em um procedimento simples recobrindo áreas cruentas até a ponta nasal, resultando em cicatrizes pouco perceptíveis. RELATO DE CASO: Paciente de 82 anos procurou o Serviço de Cirurgia Plástica do Hospital Universitário Maria Aparecida Pedrossian apresentando lesão em dorso nasal de aproximadamente 3 × 2 cm, ulcerada com base eritematosa e limites mal definidos. A técnica utilizada para correção da perda de substância foi o deslizamento de um retalho frontoglabelar com pedículo randomizado. A paciente evoluiu com viabilidade do retalho, apresentando restauração do dorso nasal e resultado estético satisfatório. CONCLUSÃO: Em decorrência da cor e textura adequadas da pele desta região, o retalho frontoglabelar é reconhecidamente uma excelente área doadora para cobertura do dorso do nariz.


INTRODUCTION: The nasal dorsum is a common location for the development of cutaneous tumors, predominantly basal cell epithelioma. In 1964, Barsky recommended a quadrangular flap for coverage of the nasal dorsum, taken from the glabellar region, to most closely match the skin of the dorsal region. This was based on a simple procedure for covering raw areas up to the nasal tip, resulting in less noticeable scars. CASE REPORT: An 82-year-old woman presented to the Plastic Surgery Service of the University Hospital Maria Aparecida Pedrossian with a lesion on the nasal dorsum of approximately 3 x 2 cm, ulcerated with an erythematous base, and ill-defined limits. A fronto-glabellar sliding flap was used to correct the loss of substance. The patient progressed with flap viability, restoration of the nasal dorsum, and satisfactory esthetic results. CONCLUSION: Owing to the color and texture of the skin from this region, the fronto-glabellar flap is an excellent donor area for coverage of the nasal dorsum.
