Reconstrucción mamaria con TRAM bipediculado. Variantes utilizadas y resultados obtenidos / Breast reconstruction with bipedicled TRAM. Variants used and results obtained

La reconstrucción mamaria utilizando el colgajo TRAM (transverse rectus abdominis muscle) bipediculado es un procedimiento poco frecuente aunque en ciertas ocasiones es de gran utilidad. Las indicaciones principales están descriptas para los casos que se requieren volúmenes de tejidos de mayor cantidad que la reconstrucción mamaria convencional, antecedentes de irradiación de grandes zonas de la pared del tórax y, en ciertas ocasiones, en reconstrucciones mamarias autólogas bilaterales. La presente publicación revisa el uso de 12 colgajos TRAM bipediculados en nuestra institución, las variantes que hemos usado y los resultados obtenidos. También se detallan elementos anatómicos de interés técnico con el objeto de reducir las complicaciones.

Breast reconstruction using the bipedicle TRAM (transverse rectus abdominis muscle) flap is a rare procedure, although it is sometimes very useful. The main indications are described for cases that require larger tissue volumes than conventional breast reconstruction, a history of irradiation of large areas of the chest wall, and on certain occasions, in bilateral autologous breast reconstructions. This publication reviews the use of 12 bipedicle TRAM flaps in our institution, the variants that we have used, and the results obtained. Anatomical elements of technical interest are also detailed to reduce complications.

Effectiveness of lobulated pedicled rectus abdominis myocutaneous flap for repairing huge chest wall defect / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect.@*METHODS@#Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly.@*RESULTS@#All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis).@*CONCLUSION@#The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.

Colgajo con preservación de papilas en defecto óseo del sector anterior / Papilla-preserving flap in bone defect of the anterior sector

RESUMEN La técnica de preservación de papilas en el tratamiento de las periodontitis ofrece ventajas en cuanto a la protección del sitio del defecto cuando en este se pretende realizar cirugía ósea aditiva. La combinación de este proceder con la regeneración tisular guiada garantiza mayor protección a la membrana colocada con este fin. Se presenta el caso de un paciente de 47 años de edad, masculino, cibernético de profesión, que recibió tratamiento periodontal pero no acudió a su fase de mantenimiento y en este momento lo hace por presentar movilidad y sangrado gingival manifestado fundamentalmente al realizar los procedimientos de higiene bucal. Se le realizó un colgajo con preservación de papilas, entre los incisivos centrales superiores, colocándole un injerto de Bio-Oss y una membrana de colágeno, con lo que se obtuvo una mayor altura del hueso y una disminución de la profundidad de la bolsa.

ABSTRACT The papillae preservation technique in the treatment of periodontitis offers advantages in terms of protecting the defect site when additive bone surgery is intended to be performed on it. The combination of this procedure with guided tissue regeneration guarantees greater protection for the membrane placed for this purpose. We present a 47-year-old male patient, computer engineer as a profession, who received periodontal treatment but did not attend his maintenance phase; he does so due to mobility and gingival bleeding manifested mainly when performing oral hygiene procedures. A papilla-preserving flap was made between the upper central incisors, placing a Bio-Oss graft and a collagen membrane, which resulted in greater bone height and decreased pocket depth.

Resumen Introducción: La úlcera por presión más frecuente es la sacra. Si compromete el hueso puede provocar osteomielitis por lo que requiere aseo quirúrgico y colgajo miocutáneo de gluteus maximus por deslizamiento en V-Y. Materiales y Método: En el servicio de cirugía plástica del hospital del Salvador entre 2011 y 2020 se han operado 82 pacientes con ulceras sacras grado 4 que requirieron cobertura con colgajo miocutáneo de gluteus maximus en V-Y. De ellas se analizaron los últimos 37 pacientes. Resultados De los 37 pacientes, 12 fueron mujeres, 25 hombres, 17 parapléjicos, 12 tetrapléjicos y 8 deambulaban. 6 pacientes presentaron COVID-19. 24 fueron bilaterales y 13 unilaterales. Los colgajos cicatrizaron bien en 30 pacientes. Las complicaciones fueron de 16% consistente en 2 hematomas, 2 dehiscencias, 2 celulitis y 1 seroma, todas resueltas sin problemas. Seguimiento de entre 3 y 6 meses. Discusión El tratamiento quirúrgico con colgajo miocutáneo de gluteus maximus en V-Y, aparte de aportar volumen para ocluir la úlcera, aporta irrigación excelente con oxígeno, nutrientes y antibióticos que aseguran una óptima cicatrización. Dependiendo del diámetro de la úlcera el colgajo puede ser uni o bilateral. Dado lo complejo del tratamiento, en general, el porcentaje de complicaciones de 16% se considera bajo. Conclusión: El tratamiento quirúrgico de las úlceras por presión sacras con colgajos miocutáneos deslizantes de gluteus maximus ha sido exitoso con buenos resultados quirúrgicos con buen flujo sanguíneo y buena evolución.

Introduction: Pressure sores are the result of the compression of soft tissues in the prominent bones areas, mainly in patients without movement. If the depth of the ulcer compromises the sacral bone, the treatment will be the gluteus maximus myocutaneous flap in V-Y. Materials and Method: In the plastic surgery service of the hospital del Salvador 82 patients with sacral pressure sores grade 4 were operated on between 2011 and 2020 with gluteus maximus myocutaneous V-Y flap. The last 37 patients were analyzed. Results: With this treatment the flaps were doing well in all cases with good blood supply. Complications: dehiscence: 2 patients, cellulitis: 2 patients, hematoma: 2 patients and seroma: 1 patient. The overall complication was 16%. Follow up between three and six months. Discussion: The most important part in pressure sores is their prevention. When the ulcer is in prominent parts of the body, the sore, could be in different grades of depth. The classification of them is in grades 1: erythema, 2: subcutaneous tissue. These two grades are solved with conservative treatment. When the ulcers are in grade 3 or 4, and with little ulcer in the skin but with damage of the deep plane, the treatment will be with surgery. In our casuistic the most frequent pressure sore is in the sacrum treated with gluteus maximus sliding myocutaneous flap in V-Y. With this treatment the flaps were doing well in all cases with good blood supply. The complications of 16% were considered low. Conclusion: The sliding gluteus Maximus myocutaneous flap in V-Y for treatment for sacral pressures sores have been successful for our patients.

Materiales y Método: La casuística es de 31 pacientes portadores de úlceras por radionecrosis resueltas con colgajos miocutáneos y fasciocutáneos. Ellos han sido pediculados y microquirúrgicos. Las edades fluctuaron entre 30 y 75 años operados entre el 2000 y el 2019. Resultados: Se realizaron 19 colgajos musculares o miocutáneos y 12 fasciocutáneos en diferentes zonas del organismo. Los colgajos correspondieron a: temporal, latissimus dorsi de pedículo central y en reversa, latissimus dorsi microquirúrgicos, recto abdominal, escapular microquirúrgico, para escapular, gracilis, gastrocnemius, rectus femoris, cubital microquirúrgico, fasciocutaneos: cone flap y de rotación local. Las complicaciones fueron dehiscencia de herida operatoria suturada y celulitis tratada con antibióticos. No hubo necrosis completa de los colgajos. El seguimiento fue de 3 a 6 meses. Discusión: En esta serie hemos utilizados los colgajos músculo cutáneos de preferencia, los fasciocutáneos los hemos reservados para aquellos casos en los que por razones anatómicas, de localización de las úlceras, era más adecuado usar estos últimos, como en las lesiones planas o poco profundas. Generalmente los colgajos fueron pediculados y en determinados casos, cuando el tejido vecino de reparación no estaba disponible, realizamos colgajos con microcirugía. Conclusión: El tratamiento de las úlceras por radionecrosis es efectivo cuando se realiza desbridamiento exhaustivo con cobertura inmediata con colgajos musculares o músculocutáneos y fasciocutáneos. Fueron colgajos pediculados y microquirúrgicos.

Introduction: The radionecrosis ulcer have to be widely resected and repaired trough flaps with good blood supply who contibute with oxigen, nutrients and antibiotics. Thinking on this the more suitable flaps are the myocutaneous ones and in special conditions the fasciocutaneous. Aim: The objetive of this paper is to show the surgical treatment of radionecrosis ulcers with myocutaneous and fasciocutaneous flaps. Materials and Method: Casuistic is 31 patients with radionecrosis ulcers treated with, mainly, myocutaneous flaps and in special areas with fasciocutaneous ones. The majority were pedicle flaps and in less number microsurgical flaps. The age of patients were betwee30 and 75 years old. Results: 19 muscle or myocutaneous flaps and 12 fasciocutaneous flaps were made. Flaps were latissimus dorsi, temporal, escapular, para escapular, rectus abdominis, rectus femoris, gracilis, gatrocnemius, cone flap and local fasciocutaneous flaps. Complications were sutured operative wound dehiscence and cellulitis treated with antibiotics. There were no complete necrosis of any flap. Discusion: In this serie we used muscle or myocutaneous flaps because they give good blood supply, oxigen, nutrients and arrival of antibiotic with filling of the deep ulcers. When the ulcers were shallow we use fasciocutaneous flaps. The majority of our flaps were pedicles and microsurgical flaps were used when there was no near avialable tissue. Conclusion: The treatment have to be wide debridement of the ulcer. The surgical treatment is with myocutaneous and fasciocutaneous flaps sometimes pediculates and in others conditions microsurgicals.

Clinical effects of free latissimus dorsi myocutaneous flap combined with artificial dermis and split-thickness skin graft in the treatment of degloving injury in lower extremity / 中华烧伤杂志

Objective: To observe the clinical effects of free latissimus dorsi myocutaneous flap combined with artificial dermis and split-thickness skin graft in the treatment of degloving injury in lower limbs. Methods: A retrospective observational study was conducted. From December 2017 to December 2020, 8 patients with large skin and soft tissue defect caused by degloving injury in lower extremity were admitted to Ningbo No.6 Hospital, including 5 males and 3 females, aged from 39 to 75 years, with wound area of 25 cm×12 cm-61 cm×34 cm. The free latissimus dorsi myocutaneous flap with latissimus dorsi muscle in the width of 12-15 cm and flap area of 20 cm×8 cm-32 cm×8 cm was used to repair the skin and soft tissue defect of bone/tendon exposure site or functional area. The other defect was repaired with bilayer artificial dermis, and the flap donor site was sutured directly. After the artificial dermis was completely vascularized, the split-thickness skin graft from thigh was excised and extended at a ratio of 1∶2 to 1∶4 and then transplanted to repair the residual wound, and the donor site of skin graft was treated by dressing change. The survival of latissimus dorsi myocutaneous flap, artificial dermis, and split-thickness skin graft after operation was observed, the interval time between artificial dermis transplantation and split-thickness skin graft transplantation was recorded, and the healing of donor site was observed. The appearance and function of operative area were followed up. At the last outpatient follow-up, the sensory recovery of flap was evaluated by British Medical Research Council evaluation criteria, the flap function was evaluated by the comprehensive evaluation standard of flap in Operative Hand Surgery, the scar of lower limb skin graft area and thigh skin donor area was evaluated by Vancouver scar scale, and the patient's satisfaction with the curative effects was asked. Results: The latissimus dorsi myocutaneous flap survived in 6 patients, while the distal tip of latissimus dorsi myocutaneous flap was partially necrotic in 2 patient and was repaired by skin grafting after resection at split-thickness skin grafting. The artificial dermis survived in all 8 patients after transplantation. The split-thickness skin graft survived in 7 patients, while partial necrosis of the split-thickness skin graft occurred in one patient and was repaired by skin grafting again. The interval time between artificial dermis transplantation and split-thickness skin graft transplantation was 15-26 (20±5) d. The donor site of latissimus dorsi myocutaneous flap healed with linear scar after operation, and the thigh skin graft donor site healed with scar after operation. The patients were followed up for 6-18 (12.5±2.3) months. The color and elasticity of the flap were similar to those of the surrounding skin tissue, and the lower limb joint activity returned to normal. There was no increase in linear scar at the back donor site or obvious hypertrophic scar at the thigh donor site. At the last outpatient follow-up, the sensation of the flap recovered to grade S2 or S3; 3 cases were excellent, 4 cases were good, and 1 case was fair in flap function; the Vancouver scar scale score of lower limb skin graft area was 4-7 (5.2±0.9), and the Vancouver scar scale score of thigh skin donor area was 1-5 (3.4±0.8). The patients were fairly satisfied with the curative effects. Conclusions: In repairing the large skin and soft tissue defect from degloving injury in lower extremity, to cover the exposed bone/tendon or functional area with latissimus dorsi myocutaneous flap and the residual wound with artificial dermis and extended split-thickness skin graft is accompanied by harvest of small autologous flap and skin graft, good recovery effect of functional area after surgery, and good quality of healing in skin grafted area.

The role of primary inguinal surgical debulking for locally advanced penile cancer followed by reconstruction with myocutaneous flap

ABSTRACT Purpose: To evaluate surgical complications and oncological outcomes of patients submitted to primary radical inguinal surgical debulking (PRISD) and myocutaneous pediculate flap reconstruction (MPFR) for locally advanced penile cancer (PC). Materials and Methods: Forty-two patients with ulcerated and/or fixed bulky inguinal masses underwent unilateral or bilateral PRISD with MPFR. Tensor fascia lata flap (TFL) was the standard of care for all patients. Additional use of the gracilis flap (GF) was carried out when necessary. Contra-lateral radical inguinal lymphadenectomy (RIL) was conduced when PRISD was performed unilaterally. Surgical complications were analyzed and stratified into minor and major according to the Bevan-Thomas classification. Adjunctive treatments were assessed and oncological outcomes analyzed. Results: Of the 42 patients evaluated, 10 (23.8%) underwent bilateral PRISD and 32 (76.2%) unilateral PRISD with contra-lateral RIL, totaling 84 lymphadenectomies. A total of 62 MPFRs were performed, 52 with TFL and 10 with GF. A total of 53 complications were identified, 49 related to PRISD with MPFR and 4 to RIL. Adjuvant chemotherapy was carried out in 16 patients. Median follow-up was 10.8 months with a median overall survival (OS) of 14.0 months against 6.0 months (p=0.006) for patients submitted to PRISD with adjuvant chemotherapy in relation to surgery alone. Conclusions: PRISD alone for advanced loco-regional PC is unlikely to promote long-term survival, although it can lead to temporary local control of the disease. Despite the feasibility of the procedure, it is related to high incidence of complications. Surgical treatment with adjuvant chemotherapy is associated with improved OS.

Platysma transverse myocutaneous flap: a 21 case series of an overlooked reconstructive method for facial skin defects / Retalho miocutâneo transverso de platisma: casuística de 21 casos de um método pouco usual de reconstrução de defeitos de pele facial

Abstract Introduction Since the first report of a platysma transverse myocutaneous flap in 1977, few articles about this flap design have been added to the literature. Objective Our aim is to describe our department's experience with platysma transverse myocutaneous flap. Methods A retrospective review of all patients undergoing platysma transverse myocutaneous flap reconstruction between 2011 and 2019. Results There were 16 men and 5 women in this series. The mean patients' age was 72.7 years old. In eight cases, we had wound complications, including four wound infections, one hematoma and three distal flap ischemia problems. Distal flap ischemia occurred only in cases that advanced beyond the midline and with length-to-width ratio equal to or over three to one. Neck dissection was performed in two of these three cases with ischemic complications. Conclusion Several factors may influence platysma transverse myocutaneous flap survival. Usually a long and narrow flap, especially crossing the neck midline and associated with neck dissection are more prone to poor outcomes.

Resumo Introdução Desde o primeiro relato de retalho miocutâneo transverso de platisma em 1977, poucos artigos sobre o assunto foram adicionados à literatura. Objetivo Descrever a experiência de nosso departamento com retalho miocutâneo transverso de platisma. Método Análise retrospectiva de todos os pacientes submetidos à reconstrução por retalho miocutâneo transverso de platisma entre 2011 e 2019. Resultados Havia 16 homens e 5 mulheres. A idade média dos pacientes foi 72,7 anos. Em oito casos, ocorreram complicações no sítio operatório: quatro infecções no sítio operatório, um hematoma e três isquemias distais do retalho. A isquemia distal do retalho ocorreu apenas nos casos em que os mesmos progrediram para além da linha média e com proporção entre comprimento e largura superior ou igual a três. A dissecção do pescoço foi feita em dois desses três casos de complicações isquêmicas. Conclusão Diversos fatores podem afetar a vitalidade do retalho miocutâneo transverso de platisma. Normalmente, um retalho longo e estreito que passa pela linha média do pescoço e está associado à dissecção do pescoço está mais propenso a resultados negativos.

Reconstrucción del labio inferior con colgajo miomucoso del buccinador por hemangioma congénito: a propósito de un caso / Reconstruction of the lower lip with myomucosal buccinator flap due to congenital hemangioma: a case report

Los labios son repliegues músculo membranosos móviles que se encuentran en la entrada de la cavidad oral, y tienen como funcionalidad proporcionar competencia para la cavidad oral durante la masticación y el reposo. Bozzola y cols., en 1989, describieron la arteria bucal como el principal pedículo para el músculo buccinador. El objetivo de este trabajo es demostrar la efectividad del colgajo miomucoso del buccinador para reconstrucción del labio inferior en un paciente con hemangioma congénito. Este es un estudio longitudinal de tipo retrospectivo, con resultado descriptivo, que se le realizó a un paciente masculino de 32 años, para cubrimiento de defecto de lesión en labio inferior secundario a hemangioma congénito utilizando la reconstrucción con colgajo miomucoso del buccinador. El colgajo miomucoso del buccinador o colgajo yugal se considera uno de los mejores colgajos locales para la reconstrucción del labio inferior, sea cual fuere la causa, por su fácil disección y versatilidad debido a que tiene una tasa de sobrevida muy elevada con mínimas complicaciones en el posoperatorio. Nuestros resultados obtenidos concuerdan con los resultados ya publicados por diferentes autores, que llegan a las mismas conclusiones; aunque existen varias técnicas con colgajos locales para la reconstrucción del labio inferior, el colgajo del músculo buccinador o yugal se considera como una de las principales alternativas, ya que puede lograrse un labio funcional y estético.

The lips are mobile muscle membranous folds, found at the entrance of the oral cavity, whose function is to provide competition for the oral cavity during chewing and rest. Bozzola et al. in 1989, they described the buccal artery as the main pedicle for the Buccinator Muscle. The objective of this work is to demonstrate the effectiveness of the buccinator myomucosal flap for reconstruction of the lower lip in a patient with congenital hemangioma. This is a retrospective longitudinal study, with descriptive results, which was performed in a 32-year-old male patient to cover a lower lip lesion defect secondary to congenital hemangioma using buccinator myomucosal flap reconstruction. The buccinator myomucosal flap or jugal flap is considered one of the best local flaps for the reconstruction of the lower lip whatever the cause, due to its easy dissection and versatility due to the fact that it has a very high survival rate with minimal complications in the postoperative period. Our obtained results agree with the results already published by different authors, reaching the same conclusions; Although there are several techniques with local flaps for the reconstruction of the lower lip, the buccinator or jugal muscle flap is considered one of the main alternatives, since a functional and aesthetic lip can be achieved.

Free rectus abdominis myocutaneous flap for the reconstruction of major and complex defects in the craniofacial regions after ablation of advanced sinonasal carcinomas / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the method and plausibility of using free rectus abdominis flap (FRAF) to reconstruct the major and complex defects in the craniofacial regions after ablation of advanced sinonasal carcinoma. Methods: From 2007 to 2018 at No. 980 Hospital of Joint Logistic Supportive Force of People's Liberation Army of China, 13 patients with advanced carcinoma of nasal cavity and paranasal sinuses, including 11 males and 2 females, aged from 33 to 67 years, were treated with FRAF to repair the invasion of skull base, face and orbit. Based on adequate and meticulous preoperative evaluations on patients and tumors, complete resection of tumor bulks was performed. According to the sites, characters and extents of the defects, FRAF was introduced in different ways into reconstruction of major and complex defects in the craniofacial regions after resection of advanced sinonasal carcinomas, restoring the structure and contour of the craniofacial region. Results: Complete resection of tumors was achieved in all cases. For repairing the major and complex defects resulted from tumor ablation, FRAF graft was conducted in 13 patients with advanced sinonasal carcinomas. The recipient vessels were facial artery and vein in 9 cases, superficial temporal artery and vein in 4 cases. Vascular bridging with the external jugular vein was carried out in 2 cases who underwent submandibular neck dissections, in which facial artery and vein were used as recipient vessels. Free fibular flap was used along with FRAF in a case undergone bilateral maxillectomy. Pedicled galea capitis and periosteal flap were applied simultaneously in 3 cases with dura defects at the skullbase resulted from tumor resection. All flaps used in 13 cases survived uneventfully without major complications, with successful repair of defects, reconstruction of structures and restoration of contour of craniofacial regions. Conclusion: With adequate evaluation of resectability of tumors as well as nature and extent of defects after tumor removal, FRAF transplantation is an ideal method and strategy of choice for reconstructing the major and complex defects in craniofacial regions resulted from tumor ablation of advanced sinonasal carcinomas.

Objective: To evaluate the functional outcomes of repairing parietal and occipital defect after surgery for cancer by lower trapezius myocutaneous flap with latissimus dorsi. Methods: Retrospective analyses of eight patients were performed who underwent repairing parietal and occipital defects with dural exposure after surgeries for cancers from January 2015 to January 2020 in Tianjin Institute of Occupational Disease Control and Prevention (Tianjin Workers Hospital) and the Second Hospital of Tianjin Medical University, including 6 males and 2 females aged from 26 to 68 years old. The method for harvesting the lower trapezius myocutaneous flap was improved and thus the lower trapezius myocutaneous flaps with latissimus dorsi were used for repairing the parietal and occipital defects. The area of myocutaneous flap depended on the size of defect. Results: The defects were repaired with the flaps with areas ranging from 12 cm×8 cm to 17 cm×15 cm. Seven flaps survived after surgery and the wounds were healed. Blisters and bruise were observed at the distal end of one flap 2 days after operation, which were cured with dressing change for 10 days. All cases were followed-up for six months, with normal functions of the shoulder joints, aside from mild hypertrophic scar in donor site on the back. Conclusion: It is feasible to use the lower trapezius myocutaneous flap with latissimus dorsi to repair the parietal and occipital defect after surgery for cancer, and the clinical effect is satisfactory.

Reconstrucción de cavidad oral con colgajo de músculo temporal: caso clínico / Reconstruction of oral cavity with temporal muscle flap: a clinical case

Objetivo: Describir la técnica de reconstrucción oral con colgajo de músculo temporal por resección de lesión oncológica. Caso clínico: Un paciente de sexo masculino, de 70 años de edad, fue derivado al Hospital Sirio Libanés desde la Facultad de Odontología de la Universidad de Buenos Aires con diagnóstico de carcinoma mucoepidermoide de siete meses de evolución, ubicado en el reborde alveolar del maxilar superior izquierdo, a nivel de las piezas dentarias 25 a 28. Se realizó la resección del tumor bajo anestesia general y la consiguiente reconstrucción del lecho mediante la técnica de reconstrucción oral con colgajo de músculo temporal. Conclusión: El colgajo temporomiofascial resultó ser versátil para la reconstrucción maxilofacial en lo que respecta a la proximidad, el tamaño, la fiabilidad de la vascularización y la facilidad de la técnica (AU)

Aim: To describe the temporalis myofacial flap technique for reconstruction in the maxillofacial region following oral cancer resection. Clinical case: A 70-year-old male patient was referred to the Sirio Libanés Hospital from the Dental School, University of Buenos Aires with a diagnosis of mucoepidermoid carcinoma with 7 months of evolution located in the alveolar ridge of the left upper jaw, at the level of teeth 25 to 28. The tumor was resected under general anesthesia and a rotational flap of the temporalis muscle was used for the reconstruction of the area. Conclusion: The temporalis flap was a versatile option for the reconstruction of maxillofacial defects due to its proximity to the oral cavity, the reliable vascularity and minor donor site morbidity (AU)

Reconstrucción Mamaria Tardia Vd / Delayed Breast Reconstruction Vd

Resumen Se presentan casos clínicos operados con la técnica de reconstrucción mamaria de grande dorsal Vd, y se muestra un procedimiento quirúrgico que permite dar un mejor terminado en cuanto a simetría, volumen y proyección. Se muestran 4 casos de reconstrucción tardía, de los cuales 2 fueron reconstrucciones tardías propiamente dichas y los otros 2 con reconstrucciones previas con complicaciones (un caso de necrosis previa de TRAM y otro con mal posicionamiento de la prótesis). Se resalta la utilización de un sistema de cierre asistido por vacío (sistema de presión negativa), un sistema no invasivo y dinámico que ayuda a promover la cicatrización en el lugar de la herida, lo que favorece la reducción del área de la herida, eliminando el exceso de fluidos y estimulando la angiogénesis. Los 4 casos se atendieron en el Instituto Nacional de Cancerología de Colombia, la Clínica San Diego y el Hospital Departamental de Villavicencio.

Abstract There are clinical cases operated with the large dorsal breast reconstruction technique Vd, and a surgical procedure is shown that allows a better finish in terms of symmetry, volume and projection. Four cases of late reconstruction are shown, of which 2 were late reconstructions themselves and the other 2 with previous reconstructions with complications (one case of previous TRAM necrosis and another with poor positioning of the prosthesis). The use of a vacuum assisted closure system (negative pressure system), a non-invasive and dynamic system that helps promote healing at the site of the wound, which favors the reduction of the wound area, eliminating excess fluids and stimulating angiogenesis. The 4 cases were treated at the National Cancer Institute of Colombia, the San Diego Clinic and the Villavicencio Departmental Hospital.

Perineal repair after abdominoperineal excision with rectus abdominis myocutaneous flap / Reconstrução do períneo após amputação abdominoperineal com retalho pediculado do músculo reto abdominal

ABSTRACT Background: Abdominoperineal excision of the rectum (APR) remains the only potential curative treatment for very low rectal adenocarcinoma and squamous cell carcinoma of the anus. Yet, it implies a significant perineal exenteration and has set the attention on the perineal reconstruction. Aim: To present technique used in one case of APR for anal cancer, with resection of the vaginal posterior wall with large perineal defect which has called for the necessity of a flap for reconstruction Method: To cover the large perineal defect and reconstruct the posterior vaginal wall was perform a standardized and reproducible surgical technique using oblique rectus abdominis myocutaneous (ORAM) flap. The overlying skin of this flap is thick and well vascularized by both superficial branches and perforators of the superior epigastric artery and the deep inferior epigastric artery which serves as the vascular pedicle for the ORAM flap. Results: This procedure was applied in a 65-year-old woman with recurrent squamous cell carcinoma of the anus infiltrating the posterior wall of the vagina. Was performed an APR with en-bloc resection of the vaginal posterior wall in order to achieve tumor-free margins. Postoperative course was uneventful and she was discharged home at postoperative day 9. Final pathological report confirmed the oncological adequacy of the procedure (R0) and showed a rypT4N0 lesion. Conclusion: Flap reconstruction is an effective way to cover the perineal wound reducing both perineal complication rate and wound healing delay. The ORAM is particularly interesting for female whose tumors require resection and subsequent reconstruction of the posterior wall of the vagina.

RESUMO Racional: A amputação abdominoperineal do reto (APR) continua sendo o único tratamento curativo nos casos de adenocarcinoma retal muito baixo e carcinoma espinocelular do ânus. No entanto, implica em exenteração perineal significativa e exige atenção na reconstrução perineal. Objetivo: Propor, ilustrando com um caso clinico, proposta de APR para câncer anal com ressecção da parede posterior da vagina com cobertura do grande defeito perineal através de reconstrução com retalho miocutâneo oblíquo do reto abdominal (ORAM). Método: Para cobrir o defeito e reconstruir a parede vaginal posterior, realizou-se técnica de retalho miocutâneo oblíquo do reto abdominal (ORAM). A pele subjacente desse retalho por ser espessa e bem vascularizada por ramos perforantes superficiais da artéria epigástrica superior e pela artéria epigástrica inferior profunda serviu como pedículo vascular. Resultado: Este procedimento foi aplicado em uma mulher de 65 anos com recidiva de carcinoma espinocelular do ânus infiltrado na parede posterior da vagina. Foi realizada APR com ressecção em bloco da parede posterior vaginal com o objetivo de obter margens livres de tumor. O pós-operatório transcorreu sem intercorrências e a paciente recebeu alta hospitalar no 9° dia pós-operatório. O relatório patológico final confirmou a adequação oncológica do procedimento (R0) e mostrou uma lesão rypT4N0 de 6,5 cm. Conclusão: A reconstrução perineal com utilização de retalho é maneira eficaz de fechar a ferida operatória, reduzindo a taxa de complicações perineais e o atraso na cicatrização. O retalho de tipo ORAM é particularmente interessante para mulheres cujos tumores requerem ressecção e subsequente reconstrução da parede posterior da vagina.

Xantogranuloma juvenil gigante: acometimento palpebral difuso e simultâneo / Giant Juvenile Xanthogranuloma: diffuse and simultaneous palpebral involvement

O xantogranuloma juvenil (XGJ) é um tumor benigno e o mais comum do grupo das doenças histiocitárias proliferativas nãoLangerhans. Lesões; 2cm são consideradas XGJ gigantes, com relatos de lesões de até 18cm. Lesões oculopalpebrais podem necessitar de tratamento cirúrgico para controle de sintomas. Esse trabalho relata o caso de um menino de 8 anos que teve as 4 pálpebras acometidas por XGJ gigantes, além do terço médio. Ele foi submetido a 3 ressecções, sendo uma bastante profunda, necessitando enxerto de pele de espessura total diretamente sobre o músculo levantador da pálpebra superior. Posteriormente, 3 procedimentos de lipoenxertia foram realizados, atingindo resultado funcional e estético adequado, sem recorrência lesional.

Juvenile xanthogranuloma (JXG) is the most common benign tumor of the group of non-Langerhans histiocytic proliferative diseases. Lesions >2 cm are considered giant JXG, with reports of lesions of up to 18 cm. Oculopalpebral lesions may require surgical treatment to control symptoms. This study reports a case of an 8-year-old boy who had four eyelids and the middle third of the face affected by giant JXG. He underwent three resections, one of which was of great depth that required a full-thickness skin graft directly on the levator palpebrae superioris muscle. Subsequently, four fat-grafting procedures were performed and adequate functional and
