ABSTRACT

Abstract Large defects in plantar surface secondary to acral melanoma excision can be difficult to repair with local flaps, and skin grafts in weight-bearing surfaces often suffer necrosis causing prolonged disability. Acellular dermal matrices represent an easy alternative to cover deep wounds or those with bone or tendon exposure. Despite their high cost and the requirement of two surgical procedures, this alternative may offer excellent functional and aesthetic results in acral defects.

ABSTRACT

Abstract Background: The ear is a region that has a high prevalence of cutaneous carcinomas and several guidelines indicate Mohs micrographic surgery as the first-choice treatment in such cases. Although the technique allows maximum preservation of healthy tissue, many auricular surgical wounds constitute a challenge due to the peculiar local anatomy, with evident curves and reliefs. Auricular reconstruction should prioritize function before aesthetics, but without leaving the latter aside, since postoperative distortions can have a significant psychological impact. Objective: To describe the authors' experience in auricular reconstruction after Mohs surgery and to evaluate the most frequently used repair methods. Methods: Retrospective study of consecutive cases submitted to Mohs surgery and auricular reconstruction, over a period of 3 years. Results: One hundred and one cases were included and the most common repair method was primary closure (n = 35), followed by full-thickness skin graft (n = 30) and flaps (n = 24). In thirty cases, reconstruction methods were associated. Seven patients had complications (partial graft necrosis, postoperative bleeding or infection). Study limitations: Retrospective design and the absence of long-term follow-up of some cases. Conclusions: The dermatologic surgeon should be familiarized with different options for auricular reconstruction. Primary closure and skin grafts were the most frequently used repair methods.

ABSTRACT

Abstract Contact electrical burns are more severe than other forms of contact burn injury. Moreover, treatment of hand burns is an important therapeutic challenge. We present a 17 year-old female of low voltage electric hand injury, admitted 5 days after injury. The patient was treated with autologous platelet rich plasma, porcine dermis heterograft and partial autologous skin graft, all of them with hyperbaric oxygen therapy (HBOT) at 1.45 ATA ≈100% O2 like adjuvant therapy. Good evolution and acceptable aesthetic results were reported. Although more studies are required, we suggest that multi-therapeutic approach could be effective in treatment for electric burns in hands.


Resumen Las quemaduras eléctricas por contacto son más graves que otras formas de quemaduras. Además, el tratamiento de las mismas en las manos es un importante desafío terapéutico. Presentamos el caso de una mujer de 17 años de edad con lesión en la mano por quemadura por electricidad de baja tensión. Fue ingresada 5 días después de la lesión y tratada con plasma rico en plaquetas autólogo, heteroinjerto de dermis porcina e injerto de piel autólogo parcial, todo con oxigenoterapia hiperbárica (TOHB) a 1.45 ATA ≈100% O2 como terapia adyuvante. Tuvo buena evolución y resultados estéticos aceptables. Aunque se requieren más estudios, sugerimos que el enfoque multi-terapéutico podría ser eficaz en el tratamiento de las quemaduras eléctricas en las manos.

ABSTRACT

INTRODUCCIÓN. Los defectos de la fosa poplítea suponen un desafío reconstructivo para el cirujano plástico, dada la relación íntima de esta área con la articulación de la rodilla y la neurovasculatura vital subyacente. El propósito de éste informe fie compartir la experiencia en la utilización de un colgajo fasciocutaneode la arteria safena. CASO CLÍNICO. Paciente de 5 años de edad que sufrió quemadura térmica en miembros inferiores con dos años y medio de evolución, ameritó injertos, presentó contractura por tejido cicatricial en fosa poplítea, dificultó la deambulación y desarrollo neuro osteomuscular. Se realizó reconstrucción de la fosa poplítea con colgajo fasciocutáneo de la arteria safena. RESULTADOS. El colgajo fasciocutáneo de la arteria safena dio cobertura al defecto en fosa poplítea izquierda tras retiro del tejido cicatricial que producía contractura, limitaba la marcha y el desarrollo neuro osteo-muscular. Seis meses postquirúrgicos brindó cobertura cutánea definitiva y estable en el área crítica, que permitió la deambulación con movimientos de extensión y flexión de rodilla conservados. DISCUSIÓN. Este colgajo al igual que en otros estudios que respaldan su ejecución brindó excelentes resultados en defectos de partes blandas a nivel de la articulación de la rodilla. CONCLUSIÓN. El colgajo fasciocutáneo de la arteria safena demostró utilidad para la reconstrucción del defecto de la fosa poplítea, posibilitó una cobertura definitiva, funcional y estética, restableció los ángulos de movilidad y favoreció el desarrollo pondoestatural del paciente.


INTRODUCTION. Defects of the popliteal fossa pose a reconstructive challenge for the plastic surgeon, because of the intimate relation of this area with the knee joint and the near vital neurovasculature; the purpose of this report was to share the experience of using a fasciocutaneous flap of the saphenous artery. CLINICAL CASE. A 5 year old patient who suffered thermal burn in lower limbs with two and a half years of evolution, he nedeed grafts and presented tissue contracture because the scar in the popliteal fossa hindered ambulation and neuro-osteomuscular growth. Reconstruction of the popliteal fossa was made it with a fasciocutaneous flap of the saphenous artery. RESULTS. The fasciocutaneous flap of the saphenous artery covered the defect in the left popliteal fossa after removal of the scar tissue that caused contracture, limited to walk and growth. Six months after surgery the flap provided definitive and secure skin coverage in the critical area, which allowed to walk with preserved knee extension and flexion movements. DISCUSSION. This flap was useful for the recons-truction of the defect of the popliteal fossa and provided excellent results in soft tissue defects in this area of the knee joint. CONCLUSION. The fasciocutaneous flap of the saphenous artery proved useful for the reconstruction of the popliteal fossa defect, it permited a definitive, functional and esthetic coverage, reestablished the angles of mobility and helped with the patient growth

ABSTRACT

OBJECTIVE@#To discuss the clinical effect of antibiotic bone cement in the treatment of infectious wound of lower extremity.@*METHODS@#From January 2016 to January 2019, 28 patients who had infection wounds of lower extremity were treated by antibiotic bone cement, including 21 males and 7 females with age of 34 to 76 (53.8±16.5) years old. The wound area after the initial debridement was 4 cm×3 cm to 12 cm×8 cm. All patients were treated with the antibiotic bone cement, when infection was controlled and fresh granulation tissue grew on the wound surface, local sutures or skin grafts were performed. The changes of white blood cell (WBC), erythrocyte sedimentation rate(ESR), C reactive protein(CRP) and positive rate of bacterial culture of wound secretions were recorded andcompared before and after 2 weeks of the operation. The healing time, recurrence rate and complications of fresh granulation on wound surface were calculated.@*RESULTS@#All patients were followed up for 3 to 6(4.3±1.2) months. After the recurrence of diabetic foot wound infection, 3 patients presented different degree of rupture, and the remaining patients had good wound healing. No serious complications such as aggravation of infection and amputation occurred. The WBC, ESR and CRP of the patients were decreased significantly after operation compared with that before operation (9.1±1.2)×109/L vs. (11.4±2.2)×109/L, (23.5±7.6) mm/ h vs. (57.1±14.9) mg/L, (44.2±13.1) mg/L vs. (89.2±26.7) mg/L (@*CONCLUSION@#The antibiotic bone cement can control infection of lower extremity wound effectively, promote the growth of fresh granulation tissue and wound healing.

ABSTRACT

Introducción: El objetivo de esta serie de casos es describir los resultados y las complicaciones de pacientes con heridas gra-ves con defecto de cobertura en zonas críticas tratadas con una matriz dérmica acelular. materiales y métodos: Se realizó una revisión retrospectiva de los pacientes con déficit de cobertura en zonas críticas tratados con matriz dérmica acelular en nuestro centro. Definimos como zona crítica al déficit de cobertura que no pueda ser tratado solo con injerto de piel. Evaluamos variables preoperatorias, intraoperatorias y posoperatorias. Resultados: Los diagnósticos iniciales fueron tumor (3 pacientes), trauma agu-do (3 pacientes) y secuela de síndrome compartimental (2 pacientes). El defecto de cobertura estaba localizado en la pierna (3 casos), en la mano (2 casos), en el muslo (1 caso), en el antebrazo (1 caso) y en el pie (1 caso). La zona crítica se caracterizó por exposición tendinosa con pérdida de peritenon (5 casos), exposición ósea y pérdida de periostio (1 caso), exposición de injerto de nervio (1 caso) y exposición de osteosíntesis (1 caso). Se registraron tres complicaciones. Dos pacientes requirieron una nueva colocación de matriz y, en otro paciente, se realizó un colgajo neurocutáneo de safeno interno por fracaso de la cobertura con membrana. Conclusiones: Los sustitutos dérmicos se caracterizan por su fácil uso y versatilidad. Esta técnica otorga protección en situaciones de exposición ósea, además de proveer un plano de deslizamiento en caso de exposición tendinosa. El uso de matriz dérmica permite, además, ahorrar el empleo de colgajos. Nivel de Evidencia: IV


Introduction: The aim of this study is to report outcomes and complications in a series of patients suffering soft tissue defects in critical areas treated using an acellular dermal matrix. Materials and Method: A retrospective review of patients with soft tissue coverage deficits in critical areas treated with acellular dermal matrix in our center over a five-year period was conducted. The preoperative variables analyzed were: age, sex, comorbidities, number of previous surgeries, size and characteristics of the critical area and cause of the coverage defect. The intraoperative variables analyzed were: size of the dermal substitute used, surgical time and complications. The postoperative variables were: incorporation of the dermal substitute, time elapsed until the placement of the skin graft, and postoperative complications. Results: The initial diagnoses were tumor (3 patients), acute trauma (3 patients) and sequelae of compartment syndrome (2 patients). The soft tissue defect was located in the leg (3 cases), in the hand (2 cases), in the thigh (1 case), in the forearm (1 case) and in the foot (1 case). In 5 cases the critical zone was characterized by tendon exposure with loss of peritenon; in one case bone exposure and loss of periosteum; in one case exposure of nerve graft and in one case exposure of osteosynthesis material. Three complications were recorded. Conclusion: Dermal substitutes are characterized by their versatility. This technique can provide protection in situations of bone exposure, in addition to providing a gliding plane in case of tendon exposure. In situations of failure or impossibility of performing a biological reconstruction, dermal substitutes havea role within reconstructive options. Level of Evidence: IV

ABSTRACT

OBJECTIVES: To analyze the histology and histomorphometry of healing associated with acellular dermal matrix in skin wounds in rabbits. METHODS: Twelve male rabbits were divided into two groups: the control group (CG) and the matrix group (MG). Three skin wounds with a total area of 20 × 20 mm were created on the dorsal region of each animal. Photographic records of the lesions taken over a 21-day period and use of the ImageJ program allowed calculation of the wound contraction rate. The lesions were biopsied on days 3, 14 and 21 for histomorphometric analysis to define the thicknesses of the dermis and epidermis (hematoxylin-eosin) and calculate the densities of type I and type III collagen (picrosirius). RESULTS: No significant difference in the healing rate was found between the groups (p>0.05). The MG presented greater epidermal thickness on day 3 (p<0.05) and on days 14 and 21 (p<0.001). The MG presented greater dermal thickness throughout the study period (p<0.05). The type I collagen density was higher in the MG throughout the study period (p<0.05), and the type III collagen density was higher in the MG on days 3 and 14 (p<0.05) and on day 21 (p<0.001). CONCLUSION: The use of acellular dermal matrix increased the thickness of the dermal and epidermal layers and the amount of type I and III collagen during skin wound healing and did not alter the rate of wound contraction.

ABSTRACT

La epidermodisplasia verruciforme es una genodermatosis precancerosa de tipo autosómica recesiva, infrecuente, de distribución mundial. Los portadores de esta enfermedad presentan una inmunodepresión celular selectiva contra determinados tipos de virus papiloma humano, sobre todo con los genotipos 5 y 8, desarrollando desde edades tempranas de la vida lesiones semejantes a pitiriasis versicolor, verrugas planas y queratosis seborreicas, muy extendidas, crónicas y refractarias al tratamiento. Es habitual la aparición de carcinomas escamosos múltiples, especialmente en el contexto de cofactores carcinogénicos como el sol. Presentamos a un paciente con diagnóstico de epidermodisplasia verruciforme, que evidenciaba lesiones tipo verrugas planas, queratosis seborreicas y carcinoma escamoso, la cual fue tratada con excéresis con margen de seguridad y reconstrucción con injerto de piel parcial y colocación de sistema de aspiración sellada al vacío con buena evolución.


Verruciform epidermodysplasia is a rare, autosomal recessive precancerous genodermatosis with a worldwide distribution. Carriers of this disease present a selective cellular immunosuppression against certain types of human papilloma virus, especially with genotypes 5 and 8, developing from early ages of life lesions similar to pityriasis versicolor, flat warts and seborrheic keratoses, very widespread, chronic and refractory to treatment. Multiple squamous cell carcinomas are common, especially in the context of carcinogenic cofactors such as the sun. We present a patient with a diagnosis of verruciform epidermodysplasia, who evidenced flat wart-like lesions, seborrheic keratoses and squamous carcinoma, which was treated with excision with a margin of safety and reconstruction with partial skin graft and placement of a vacuum-sealed aspiration system with good evolution.

ABSTRACT

Background : Chronic elbow dislocation is defined as untreated elbow dislocation for longer than 2 weeks. Goal of treatment is stable reduction of elbow joint and facilitation of early elbow motion for optimal end result. Known operative methods is the Kocher posterolateral approach.which can accumulate hematome, and longer time needed to identify Ulnar nerve. Therefore, we would like to introduce the new modified medial elbow joint incision approach. Methodology: This study utilized a cross-sectional review of patients with surgical treatment of simple chronic elbow dislocation. Questionnaires were taken using Oxford Elbow Score, Mayo Elbow Performance Index, and Disability of Arm, Shoulder, and Hand Questionnaire to assess current elbow status Result : Utilizing Oxford elbow score, the analytic group score value ranged from 21-46, while control group's score value were 37-42 (P-value <0.0001). Mayo Elbow Performance Index score, from the analytic group, scored ranges from 45 - 82. the control group, a mean value of 85 were scored (P-value <0.0001), the DASH score revealed total mean value of 8.3 in the analytic group, compared to score 6 in the control group (P-value = 0.0468 ). The range of motion is increased in total flexion and extension from both groups(P-value <0.0001) Conclusion: Modified medial elbow approach provides faster method of identifying ulnar nerve, requires less skin flap for closure and less space for blood accumulation. Modified medial elbow approach provides good functional outcome with no complications related to ulnar nerve reported in this study.

ABSTRACT

Introducción. Múltiples técnicas han sido descriptas para la reconstitutición de la función del pulgar quemado, aunque sin relación costo-beneficio. El colgajo en cometa, descripto por Foucher en 1979, aporta cobertura cutánea, sensibilidad y permite mejoría funcional. El objetivo de este trabajo es presentar nuestra experiencia y resultados utilizando el kite flap. Materiales y métodos. Se realiza un estudio restrospectivo, descriptivo, de 4 casos de secuelas de quemaduras en pulgar de la mano atendidas en el Servicio de Cirugía Plástica y Reparadora del Hospital de Quemados de la Ciudad de Buenos Aires en un periodo comprendido desde el año 2016 al 2019. Se realizan colgajos en cometa en isla o tunelizados y posterior rehabilitación kinésica. El seguimiento mínimo de la serie es de 3 meses y se toman registros fotográficos pre-, intra- y posoperatorios. Las variables analizadas incluyen: sufrimiento de colgajos, dehiscencia, congestión venosa, prendimiento de injertos en zona dadora, reintervenciones y mejoría en la función de abducción del pulgar y pinza de la mano. Resultados. Se realizaron 3 colgajos en cometa tunelizados y 1 en isla. La totalidad se presentaron vitales aunque con congestión venosa en las primeras 72 hs. No se registraron complicaciones y no fueron necesarias reintervenciones. La mejoría en la función de pinza y de abducción del pulgar fue objetivable mediante la observación y referida por los pacientes y/o familiares según correspondiera. Conclusiones. Creemos que el colgajo en cometa es la mejor opción de tratamiento para las secuelas de quemadura en pulgar por aportar adecuada cobertura cutánea, ser técnicamente sencillo y poder hallar el pedículo en el 100% de la población. La congestión venosa es la regla, aunque también la supervivencia, siendo la morbilidad de la zona dadora mínima y la mejoría en la función de pinza y abducción del pulgar francamente objetivable.


Introduction. Multiple techniques have been described for repair the burned thumb function, although without cost-benefit ratio. The kite flap described by Foucher in 1979, provides skin coverage, sensitivity and allows functional improvement. The goal of this study it to present our experience and results obtained using the kite flap Materials and methods. A retrospective, descriptive study of 4 cases of burned hand's thumb treated in the Plastic Surgery Unit of the Hospital de Quemados on Buenos Aires in a three year's period from 2016 to 2019. Island or tunneled's kite flaps and subsequent kinesic rehabilitation are performed. The minimum follow-up of the series is 3 months and fotographic records pre, intra and postoperative are taken. The variables analyzed include: suffering from flaps, dehiscence, venous congestion, grafting losts on the donor zone, reinterventions and improvement in the function of thumb abduction and hand clamp . Results. 3 tunelled kite flaps and 1 on island were made. All of them were vital, although with venous congestion in the first 72 hours. No complications were recorded and no reinterventions were necessary. The improvement in hand clamp function and thumb abduction was marked through observation and when it posible, referred by patients. Conclusions. We believe that kite flap is the best option of treatment for sequelae of burns affecting hand's thumb for providing adequate skin coverage, being technically simple and being able to find the pedicle at 100% of the population. Venous congestion is the rule, although survival is also. Donor zone´s morbidity is minimal and the improvement in thumb function is clear

ABSTRACT

This work aimed to evaluate the effect of platelet-rich plasma (PRP) on advancement skin flaps in dogs regarding improvement of vascularization, with focus on increasing its viable area, since there are reports that it is a potential angiogenesis stimulator. The experimental group was composed of eight adult bitches, in which two advancement skin flaps were made in the ventral abdominal region. No product was applied in the control flap (CF), while PRP was used in the contralateral flap, called treated flap (TF). The areas were clinically evaluated every two days until the 7th postoperative day regarding skin color and presence of necrosis. At 10 days, both flaps were removed and submitted to histological examination and blood vessel morphometry. The vessels counted in each group were statistically analyzed by the F-test at 1% probability. Results showed no significant difference in macroscopic changes in the wound, or CF and TF vascularization, thus suggesting that PRP gel did not improve advancement skin flap angiogenesis in bitches under the experimental conditions in which this research was developed.(AU)


Objetivou-se com o presente artigo avaliar a ação angiogênica do gel de plasma rico em plaquetas (PRP) em flapes cutâneos de avanço em animais da espécie canina, visando aumentar a viabilidade da pele após o procedimento, uma vez que existem relatos de que o produto é um potente estimulador da angiogênese. O grupo experimental foi composto por oito cadelas adultas, onde foram confeccionados dois flapes de avanço (de padrão subdérmico) na região abdominal ventral. Em um dos flapes, considerado controle (FC) não foi aplicado nenhum produto, enquanto que no flape contralateral, denominado tratado (FT), foi usado o gel de PRP. As áreas foram macroscopicamente avaliadas a cada dois dias até o 7º dia de pós-operatório em relação à coloração da pele e presença de área de necrose, e com 10 dias ambos os flapes foram coletados por biópsia e submetidos ao exame histológico e morfometria dos vasos sanguíneos. Os vasos contados em cada grupo foram estatisticamente analisados pelo teste de F ao nível de 1% de probabilidades. Os resultados demonstraram que não houve diferença significativa nas alterações macroscópicas das feridas e na morfometria vascular dos FC e FT, sugerindo dessa maneira que dentro das condições experimentais nas quais a pesquisa foi executada, que o gel de PRP não incrementou a angiogênese de flapes de avanço em cadelas.(AU)

ABSTRACT

Introducción. Las retracciones cicatrizales secundarias a quemaduras representan un desafío para el cirujano plástico debido a la variabilidad en su complejidad y presentación. La pérdida de movimiento del codo conlleva una limitación funcional con impacto directo en la calidad de vida, por lo que la indicación quirúrgica se hace necesaria. La gran variedad de tácticas quirúrgicas plantean la necesidad de sistematizar el tratamiento de las retracciones cicatrizales. Objetivo. El objetivo de esta presentación es la aplicación de la sistemática en el tratamiento de la secuela posquemadura de codo en el Servicio de Cirugía Plástica del Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires durante los últimos 10 años. Material y métodos. Mediante un diseño observacional, descriptivo y retrospectivo, se realizó el presente trabajo sobre pacientes con diagnóstico de retracción cicatrizal posuemadura en codo de agosto de 2008 a agosto de 2018. El criterio de inclusión fue pacientes entre 3 y 65 años sometidos a cirugías reconstructivas para la liberación de contracturas del codo posteriores a una quemadura durante el período mencionado. Se realizó una revisión de las historias clínicas y se evaluaron los casos a través del examen físico y de documentación fotográfica, y se analizaron diferentes variables: sexo, edad, comorbilidades, clasificación de gravedad, grado de retracción pre- y posoperatoria, tipo de reconstrucción empleada y complicaciones. Las variables mencionadas se registraron en tablas. Resultados. Treinta y cuatro pacientes operados, 20 mujeres y 14 hombres. El rango de edad fue de 3 hasta los 50 años, con una media de 21,2 años. La causa más frecuente de quemadura fue el agua caliente. El grado de retracción fue leve en 41,17% (14 casos), moderada en 47,05% y severa en 11,7%. El procedimiento más utilizado fueron los colgajos pediculados (50%), seguido por los colgajos locales (41,2 %) y, por último, se emplearon injertos de piel (8,8%). Dentro de los colgajos pediculados, el más utilizado fue el colgajo antecubital (12 casos) con un 70,6%, seguido por el colgajo braquial lateral con un 23,5% y, por último, con un solo caso, un colgajo propeller, que representó el 5,9%. Dentro de las plásticas locales, los colgajos de avance representaron el 42,8%, seguidos por las zetaplastias en un 35,7%, los colgajos de transposición en un 14,3% y la w plastia en un 7,14%. Todos los injertos de piel realizados fueron de espesor total. Las complicaciones fueron dehiscencia del borde del colgajo y epidermólisis. La ganancia objetiva de extensin en grados fue entre 5 y 80 grados. Conclusiones. Podemos concluir que es posible la aplicación de nuestro algoritmo para el tratamiento en la secuela cicatrizar en codo. Siempre que sea posible, se recomienda utilizar un colgajo fasciocutáneo por su mejor cobertura, resistencia y poca morbilidad de obtención. Todo método quirúrgico debe acompañarse con medidas no quirúrgicas como la ferulización y la rehabilitación kinésica temprana para lograr un resultado sostenido en el tiempo.


Introduction. Burn injuries to the elbow can lead to significant functional impairment and major aesthetic problems. This represents a challenge for the plastic surgeon due to the variability in their complexity and presentation. The elbow can be constructed with a wide range of surgical technique such as skin grafts, local, regional or free flaps. However, contractures vary greatly, depending on the loss of function, depth and extension of tissue involvement, and duration of scarring and, therefore, surgical intervention should be tailored for each patient. Objective. To present our experience and systematic approach for releasing postburn elbow contractures. Materials and methods. A retrospective review of the cases of post-burn elbow contractures treated in our center between August of 2008 and August of 2018 was conducted. Results. Since 2008 we have treated 34 patients. They included 20 female patients and 14 male patients. The average age was 21,2 years (range 3-50 years) at the time of the first corrective operation. Severity of elbow contracture was graded as mild in 41,17% of the cases, moderate in 47,05% and severe in 11,7%. Contractures were treated with fascio cutaneous pedicled flaps in 50% of the cases, with local flaps in 41,2% of the cases and with skin graft in 8,8%.Of the fascio cutaneous flaps employed, 12 patients were treated with an antecubital flap, 4 with a lateral arm flap and 1 with a propeller flap. Among the local flaps, z plasties and advancement flaps were the most commonly used. Elbow excursion improved in all cases between 5 and 80 degrees Conclusions. Severe elbow contracture resulting from burn injury can be treated using a systematic approach according to the physical characteristics of the contracture. Although there are many techniques of soft-tissue coverage to treat elbow contractures, we advocate using well-vascularized fascio cutaneous flaps to provide coverage due to their resistance and low donor site morbidity.

ABSTRACT

ABSTRACT Purpose: To determine the long-term functional and cosmetic outcomes in patients who underwent modified Hughes procedure with different types of anterior lamellar reconstruction for lower eyelid defects. Methods: This study included 58 patients who had undergone a modified Hughes flap for reconstruction of lower eyelids after tumor excision within a 10-year period. Data regarding patient demographics, size of eyelid defect, tumor pathology, surgical techniques, functional and cosmetic outcomes, and complications were recorded. Postoperative complications were evaluated according to the type of anterior lamella reconstruction (i.e., advancement flap or free skin graft). Multivariate logistic regression analysis was performed to identify risk factors affecting the success of the procedure. Results: The average size of the lower eyelid defect was 22 ± 6.3 mm (range: 11-30 mm). The anterior lamella was reconstructed with advancement flaps and full-thickness skin grafts in 36 (58.6%) and 24 (41.4%) patients, respectively. Mean follow-up time was 23.6 ± 11.9 months. Postoperative complications included trichiasis (three patients; 5.2%), ectropion (two patients; 3.0%), flap necrosis (one patient; 1.7%), flap dehiscence (one patient; 1.7%), infection (one patient; 1.7%), and eyelid margin erythema (one patient; 1.7%). The rates of complication and secondary surgery were similar among the different types of anterior lamellar reconstruction (p=768 and p=0.139, respectively). Success of the modified Hughes procedure was not significantly affected by any of the identified risk factors (p>0.05). Functional and cosmetic outcomes were 96.6% and 94.8%, respectively. Conclusion: Modified Hughes procedure is a safe and effective option for the reconstruction of small and large defects of the lower eyelid, regardless of the type of anterior lamella reconstruction (i.e., advancement flap or skin graft).


RESUMO Objetivo: Determinar os resultados funcionais e cosméticos a longo prazo de pacientes submetidos ao procedimento de Hughes modificado com diferentes tipos de reconstrução lamelar anterior para defeitos palpebrais inferiores. Métodos: Este estudo incluiu 58 pacientes que foram submetidos a um retalho de Hughes modificado para reconstrução das pálpebras inferiores após excisão do tumor durante um intervalo de 10 anos. Dados referentes à demografia dos pacientes, tamanho do defeito palpebral, patologia tumoral, técnicas cirúrgicas, resultados funcionais e cosméticos e complicações foram registrados. As complicações pós-operatórias foram avaliadas de acordo com o tipo de reconstrução da lamela anterior (ou seja, retalho de avanço ou enxerto de pele livre). A análise de regressão logística multivariada foi realizada para identificar os fatores de risco que afetam o sucesso do procedimento. Resultados: O tamanho médio do defeito da pálpebra inferior foi de 22 ± 6,3 mm (11-30 mm). A lamela anterior foi reconstruída com retalhos de avanço e enxertos de pele de espessura total em 36 (58,6%) e 24 (41,4%) pacientes, respectivamente. O tempo médio de acompanhamento foi de 23,6 ± 11,9 meses. Complicações pós-operatórias incluíram triquíase (três pacientes: 5,2%), ectrópio (dois pacientes: 3%), necrose de retalho (um paciente: 1,7%), deiscência de retalho (um paciente: 1,7%), infecção (um paciente: 1,7%) e eritema na margem palpebral (um paciente: 1,7%). As taxas de complicação e de cirurgia secundária foram semelhantes entre os diferentes tipos de reconstrução lamelar anterior (p=768 e p=0,139, respetivamente). O sucesso do procedimento de Hughes modificado não foi significativamente afetado por nenhum dos fatores de risco identificados (p>0,05). Resultados funcionais e cosméticos foram de 96,6% e 94,8%, respetivamente. Conclusão: O procedimento de Hughes modificado é uma opção segura e eficaz para a reconstrução de pequenos e grandes defeitos da pálpebra inferior, independentemente do tipo de reconstrução da lamela anterior (ou seja, retalho de avanço ou enxerto de pele).

ABSTRACT

Natural dermal matrix has good biocompatibility and can serve as " biological template" in wound repair. According to the source of material, natural dermal matrix can be divided into acellular dermal matrix (ADM), denatured dermal matrix, and scar dermal matrix. ADM is a biological material prepared by removing cellular components from the skin and retaining extracellular matrix (ECM) of the dermis. ADM possesses abundant natural biological information, low immunogenicity, and excellent regenerative capacity, which has greatly promoted the development of wound healing specialty as dermal substitute. Denatured dermis matrix is a layer of dermal tissue made by superficial tangential excision or dermabrasion on deeply burned wounds. The retained denatured dermis can recover gradually after transplantation of autologous skin on its surface, with similar structure, morphology, and biomechanics to healthy dermis. Scar dermal matrix is a kind of dermal scaffold made of autologous split-thickness scar tissue, possessing the characteristics of high survival rate, good texture, and slight scar reaction. Scar dermal matrix can effectively reduce secondary damage to the donor site when repairing scar contracture deformity. Based on the research progress at home and abroad and the opinions of domestic experts, this paper summarizes the indications, application methods, contraindications, and considerations of different types of natural dermal matrix in application of wound repair.

ABSTRACT

OBJECTIVE@#To evaluate the effects of membrane induced by antibiotic-loaded bone cement in skin grafting for tendon exposed wound healing.@*METHODS@#A total of 10 traumatic patients with tendon exposed wound were admitted to our department between February 2016 and December 2018, including 6 males and 4 females, with a mean age of 34.6 years old (ranged, 19 to 43 years old), and treatment duration ranged from 2 to 6 months. There were 7 cases of traffic accidents, 3 cases of mechanical belt injuries, including 8 cases of lower leg and foot wounds and 2 cases of hand back wounds. These tendons exposed wound were covered by antibiotic-loaded bone cement at the earlier stageto induce the formation of the biomembrane, and then skin grafting were performed on the induced membrane. The survival, appearance, texture, sensation of the skin grafting and healing condition of the wounds were studied.@*RESULTS@#Among the 10 patients, skin graft survived well in 8 patients. Partial skin graft necrosis occurred in 2 patients and cured by dressing.@*CONCLUSION@#Using antibiotic bone cement to seal the wound to form induction membrane followed by skin grafting can effectively repair the tendon exposed wound, which has the characteristics of simple operation and less trauma.

ABSTRACT

OBJECTIVE@#To explore clinical effect of internal and external fixation combined with second-stage perforator fiap for the treatment of ankle fracture dislocation of Gustilo-Anderson types ⅢB and ⅢC.@*METHODS@#From May 2014 to July 2017, 20 patients with Gustilo-Anderson types ⅢB and ⅢC ankle fracture dislocation were treated with internal and external fixation combined with second-stage perforator fiap, including 14 males and 6 females, aged from 18 to 58 years old with an average of (39.0±9.7) years old;17 patients were type ⅢB and 3 patients were type ⅢC according to Gustilo-Anderson classification;4 patients were type A, 7 patients were type B, and 9 patients were type C according to AO classification. The size of wound ranged from 4 cm×3 cm to 20 cm×9 cm. Second-stage perforator flap, 11 patients were performed with posterior tibial artery perforator flap, 5 patients were performed with fibular artery perforator flap, 1 patient was performed with anterior ankle flap, and 3 patients were performed with posterior tibial artery perforator flap combined with fibular artery perforator flap. Postoperative wound healing, flap survival and fracture healing were observed, AOFAS score was used to evaluate at the latest follow up.@*RESULTS@#All limbs were preserved successfully without amputation. Nine patients occurred superficial infection without deep infection and osteomyelitis occurring. The flaps of 19 patients survived. All patients were followed up for 6 to 18 months with an average of (12.0±2.9) months. The flaps healed well without sinus tract, bone exposure and bone disunion occurring. Fracture healing time ranged from 4 to 10 months with an average of (6.6±1.7) months. PostoperativeAOFAS score was 76.7± 16.4, among which 4 patients got excellent result, 11 patients good, 3 patients fair, and 2 poor.@*CONCLUSION@#Internal and external fixation combined with second stage perforator fiap for the treatment of ankle fracture dislocation of Gustilo-Anderson types ⅢB and ⅢC could effectively close the wound, improve fracture healing and restore appearance and function of limbs to the maximum.
