ABSTRACT

Using the serratus anterior fascia may be a safe and effective option to recreate the lateral breast profile during subpectoral breast reconstruction, with minimal functional impact on the donor site. However, the literature is scarce when it comes to studies on this fascia flap in implant-based reconstruction. This article aimed to review the use of the serratus anterior fascia in immediate implant-based breast reconstruction, searching the electronic databases PubMed, Embase, Lilacs, and SciELO. The search was carried out by combining the following keywords: 'breast reconstruction' and 'serratus anterior fascia'. In the Pubmed and Embase databases, the search yielded a total of 12 and 15 articles, respectively, of which seven were selected according to the scope of this article. We found no studies on serratus anterior fascia and breast reconstruction in the Lilacs and SciELO databases. All works have results favorable for the use of the serratus anterior fascia flap and agree that this technique can be considered in the algorithm for the coverage of the inferolateral portion during subpectoral breast reconstruction

ABSTRACT

O aumento do dorso nasal nas rinoplastias é foco de estudo de diversos trabalhos que buscam as melhores fontes de enxerto e técnicas cirúrgicas. A utilização de cartilagem já é consagrada para este fim, a partir do septo nasal, da concha auricular ou dos arcos costais. Nos últimos anos, têm-se buscado meios para reduzir a palpabilidade e dispersibilidade dos enxertos cartilaginosos. Assim, são descritos materiais sintéticos, como o SURGICEL®; e, autólogos, representados pelas fáscias. A fáscia temporal é mais amplamente utilizada, porém requer uma nova incisão cirúrgica, aumentando o tempo e a morbidade da cirurgia. É também descrito o uso de fáscia lata e fáscia reto abdominal, comparativamente mais espessas e menos flexíveis. Em muitos casos de rinoplastia fazse necessária a retirada da cartilagem costal, o que permite a coleta de fáscia do músculo peitoral maior pela mesma incisão cirúrgica. Dessa forma, descrevemos a utilização da fáscia do músculo peitoral maior envolvendo cartilagem costal picada, em uma rinoplastia estruturada com aumento do dorso.


Increasing the nasal dorsum in rhinoplasty is the focus of several studies that seek the best graft sources and surgical techniques. The use of cartilage from the nasal septum, ear shell, or costal arches is already established for this purpose. In recent years, methods have been sought to reduce the palpability and dispersibility of cartilaginous grafts. Thus, synthetic materials such as SURGICEL® and autologous materials such as fascia have been explored. Temporal fascia are more widely used but require a new surgical incision, increasing surgical time and morbidity. Also described is the use of fascia lata and rectus abdominis fascia, which are comparatively thicker and less flexible. In many rhinoplasty procedures, it is necessary to remove the costal cartilage, which allows the collection of fascia from the major chest muscles through the same surgical incision. Thus, we describe the use of major chest muscle fascia and chopped costal cartilage in structured rhinoplasty to increase the dorsum.

ABSTRACT

Abstract Objective The present study aims to evaluate the use of the reverse-flow sural fasciocutaneous flap to cover lesions in the distal third of the lower limb. Methods A total of 24 cases were analyzed, including 20 traumatic injuries, 3 sports injuries, and 1 case of tumor resection. Results Among the 24 evaluated medical records, 16 patients were male, and 8 were female. Their age ranged from6 to 75 years old. Most of the patients evolved with total healing of the flap (n= 21). There was only one case of total necrosis of the flap in an insulin-dependent diabetic, high blood pressure patient, evolving to subsequent limb amputation. In two cases, there was partial necrosis and subsequent healing by secondary intention; one of these patients was a heavy smoker. Complications were associated with comorbidities and, unlike other studies, no correlation was observed with the learning curve. There was also no correlation with the site or size of the lesion to be covered. Conclusion It is clinically relevant that the success rate of the reverse-flow sural fasciocutaneous flap technique was of 87.5%. This is a viable and effective alternative in the therapeutic arsenal for complex lower limb lesions.


Resumo Objetivo Avaliar o uso do retalho fasciocutâneo sural de fluxo reverso na cobertura de lesões no terço distal dos membros inferiores. Métodos Foram analisados 24 casos, 20 de origem traumática, três por lesões esportivas e um por ressecção de lesão tumoral. Resultados Dos 24 prontuários avaliados, 16 eram homens e oito mulheres. A idade variou de seis a 75 anos. A maioria dos pacientes evoluiu com cicatrização total do retalho (21). Houve apenas um caso de necrose total do retalho em paciente diabético insulinodependente e hipertenso, evoluiu para posterior amputação do membro. Em dois casos, houve necrose parcial composterior cicatrização por segunda intenção, um desses pacientes era tabagista pesado. As complicações foram associadas às comorbidades e, ao contrário do evidenciado por outros estudos, não houve correlação com a curva de aprendizado. Também não houve correlação com o local ou o tamanho da lesão a ser coberta. Conclusão Tem-se como relevância clinica que a técnica de retalho fasciocutâneo sural de fluxo reverso usada obteve 87,5% de sucesso, é uma opção viável e eficaz no arsenal terapêutico das lesões complexas dos membros inferiores.

ABSTRACT

Abstract Introduction Different types of autologous graft materials are used for myringoplasty, with the temporalis fascia and cartilage being the most frequently used tissues. Periosteal tissue has been used for a long time in our department, and many advantages support its use in myringoplasty. To the best of our knowledge, this issue is scarcely discussed in the previously published literature. Objective To present our experience with periosteal graft myringoplasty, describing the technique and the anatomical and functional outcomes. Methods A prospective clinical study involving 88 patients (72 females and 16 males) with a mean age 26.9 years. The patients underwent myringoplasty using the mastoid cortex periosteum; they were all operated using the postauricular approach, and the graft was applied using the underlay technique. The patients performed pre- and postoperative pure tone audiometry for tested frequencies (0.5 kHz, 1 kHz, 2 kHz, and 4 kHz). All patients were followed-up for at least 12 months after the operation. Results The anatomical success rate among all patients was of 93%, which is comparable to the rate of success in procedures using other usual grafting materials. In addition, there was a highly significant postoperative improvement in pure tone audiometry results as compared with the preoperative ones (the main hearing gain was of ∼ 11 dB; p< 0.001). Conclusion The periosteal graft is easily harvested, easy to apply, with excellent anatomical and functional success.

ABSTRACT

Abstract Introduction: Surgical repair of the tympanic membrane, termed a type one tympanoplasty is a tried and tested treatment modality. Overlay or underlay technique of tympanoplasty is common. Sandwich tympanoplasty is the combined overlay and underlay grafting of tympanic membrane. Objective: To describe and evaluate the modified sandwich graft (mediolateral graft) tympanoplasty using temporalis fascia and areolar fascia. To compare the clinical and audiological outcome of modified sandwich tympanoplasty with underlay tympanoplasty. Methods: A total of 88 patients of chronic otitis media were studied. 48 patients (Group A) underwent type one tympanoplasty with modified sandwich graft. Temporalis fascia was underlaid and the areolar fascia was overlaid. 48 patients (Group B) underwent type one tympanoplasty with underlay technique. We assessed the healing and hearing results. Results: Successful graft take up was accomplished in 47 patients (97.9%) in Group A and in 40 patients (83.3%) Group B. The average Air-Bone gap closure achieved in Group A was 24.4 ± 1.7 dB while in Group B; it was 22.5 ± 3.5 dB. Statistically significant difference was found in graft healing rate. Difference in hearing improvement was not statistically significant. Conclusion: Double layered graft with drum-malleus as a 'meat' of sandwich maintains a perfect balance between sufficient stability and adequate acoustic sensitivity.


Resumo Introdução: O reparo cirúrgico da membrana timpânica, denominado timpanoplastia tipo 1, é uma modalidade de tratamento já bem estabelecida. As técnicas overlay ou underlay de timpanoplastia são comuns. A timpanoplastia "sanduíche" é a técnica de enxerto de membrana timpânica overlay e underlay combinadas. Objetivo: Descrever e avaliar a timpanoplastia com a técnica "sanduíche" modificada (timpanoplastia mediolateral) utilizando fáscia temporal e fáscia aureolar. Comparar o desfecho clínico e audiológico da timpanoplastia com a técnica "sanduíche" modificada com o da timpanoplastia com a técnica underlay. Método: Foram estudados 88 pacientes com otite média crônica, 48 (Grupo A) foram submetidos à timpanoplastia tipo 1 com enxerto "sanduíche" modificado. A fáscia temporal foi utilizada na técnica underlay e a fáscia areolar na técnica overlay. 48 pacientes (Grupo B) foram submetidos à timpanoplastia tipo 1 com a técnica underlay. Foram avaliados os resultados da cicatrização e da audição. Resultados: O sucesso do enxerto ocorreu em 47 pacientes (97,9%) no Grupo A e em 40 (83,3%) do Grupo B. O fechamento médio do gap aéreo-ósseo no Grupo A foi de 24,4 ± 1,7 dB, enquanto no Grupo B foi de 22,5 ± 3,5 dB. Houve diferença estatisticamente significativa na taxa de cicatrização do enxerto. A diferença na melhora auditiva não foi estatisticamente significante. Conclusão: O enxerto de camada dupla e o tímpano-martelo posicionados como o "recheio" do sanduíche mantém um equilíbrio perfeito entre a estabilidade necessária e adequada sensibilidade acústica.

ABSTRACT

Abstract Introduction: Various graft materials have been used to close tympanic membrane perforations. In the literature, there are few studies in pediatric populations comparing different graft materials. To our knowledge, there is no reported study that measured the thickness of the tragal cartilage in pediatric tympanoplasties. The tragal cartilage is not of uniform thickness in every patient. Objective: To compare anatomical and functional outcomes of temporalis fascia muscle and full-thickness tragal cartilage in type 1 pediatric tympanoplasties. Methods: In total, 78 patients (38 males, 40 females; average age 10.02 ± 1.98 years; range, 7-18 years) who underwent type 1 tympanoplasties in our clinic were included. Demographics, anatomical, and functional outcomes were collected. Temporalis fascia muscle and tragal cartilage were used as graft materials. Tragal cartilage was used without thinning, and the thickness of tragal cartilage was measured using a micrometer. Anatomical and functional outcomes of cartilage and fascia were compared. Audiometric results comparing the cartilage and fascia groups were conducted at 6 months, and we continued to follow the patients to 1 year after surgery. An intact graft and an air-bone gap ≤ 20 dB were regarded as a surgical success. Results with a p-value < 0.05 were considered statistically significant. Results: The graft success rate was 92.1% for the cartilage group compared with 65.0% for the temporal fascia group. In the fascia group, the preoperative air-bone gap was 33.68 ± 11.44 dB and postoperative air-bone gap was 24.25 ± 12.68 dB. In the cartilage group, the preoperative air-bone gap was 35.68 ± 12.94 dB and postoperative air-bone gap was 26.11 ± 12.87 dB. The anatomical success rate in the cartilage group was significantly better than that for the fascia group (p < 0.01). There was no statistically significant difference in functional outcomes between the fascia and cartilage groups (p > 0.05). The average thickness of tragal cartilage in the pediatric population was 0.693 ± 0.094 mm in males and 0.687 ± 0.058 mm in females. Conclusions: Our data suggest that the anatomical success rate for a cartilage tympanoplasty was higher than for a fascia tympanoplasty. Functional results with cartilage were not different than with fascia, even though we did not thin the tragal cartilage. However, further studies should focus on the interaction between the thickness of the tragal cartilage and the tympanoplasty success rate.


Resumo Introdução: Vários materiais de enxerto foram usados para o fechamento da perfuração da membrana timpânica. Há poucos estudos na literatura que comparam diferentes materiais de enxerto em populações pediátricas. De acordo com nossa pesquisa, não há estudo que tenha medido a espessura da cartilagem tragal em timpanoplastia pediátrica. A espessura da cartilagem tragal não é uniforme em todos os pacientes. Objetivo: Comparar os resultados anatômicos e funcionais da fáscia do músculo temporal e da cartilagem tragal com espessura total em timpanoplastias tipo 1 em crianças. Método: No total, 78 pacientes (38 do sexo masculino, 40 do sexo feminino; média de idade de 10,02 ± 1,98 anos; variação: 7-18 anos) submetidos a timpanoplastia tipo 1 em nossa clínica foram incluídos. Os resultados demográficos, anatômicos e funcionais foram registrados. A fáscia do músculo temporal e a cartilagem tragal foram usadas como materiais de enxerto. A cartilagem tragal foi usada sem fresagem e a sua espessura foi medida com um micrômetro. Os resultados anatômicos e funcionais da cartilagem e da fáscia foram comparados. Os resultados audiométricos comparando os grupos (cartilagem e fáscia) foram avaliados em 6 meses, e o acompanhamento dos pacientes prosseguiu até 1 ano após a cirurgia. Enxerto intacto e um intervalo aéreo-ósseo (gap) ≤ 20 dB foram considerados como sucesso cirúrgico. Os resultados com um valor p < 0,05 foram considerados estatisticamente significantes. Resultados: A taxa de sucesso do enxerto foi de 92,1% para o grupo cartilagem e de 65,0% para o grupo fáscia temporal. No grupo fáscia, o gap no pré-operatório foi 33,68 ± 11,44 dB, e 24,25 ± 12,68 dB no pós-operatório. No grupo cartilagem, o gap no pré-operatório foi 35,68 ± 12,94 dB, e 26,11 ± 12,87 no pós-operatório. A taxa de sucesso anatômico no grupo cartilagem foi significantemente melhor que a do grupo fáscia (p < 0,01). Não houve diferença estatisticamente significante nos resultados funcionais entre os grupos fáscia e cartilagem (p > 0,05). A espessura média da cartilagem tragal na população pediátrica foi 0,693 ± 0,094 mm em meninos e 0,687 ± 0,058 mm em meninas. Conclusões: Nossos dados sugerem que a taxa de sucesso anatômico para uma timpanoplastia com enxerto de cartilagem seja maior que a de uma timpanoplastia com enxerto de fáscia. Os resultados funcionais com cartilagem não foram diferentes daqueles com fáscia, embora não tenhamos fresado a cartilagem tragal. Porém, novos estudos devem concentrar-se na relação entre a espessura da cartilagem tragal e a taxa de sucesso da timpanoplastia.

ABSTRACT

ABSTRACT INTRODUCTION: Promising treatments for tympanic membrane perforation closure have been studied. Therapies derived from tissue engineering probably eliminate the need for conventional surgery. Bacterial cellulose is presented as an alternative that is safe, biocompatible, and has low toxicity. OBJECTIVES: To investigate the effect on healing of direct application of a bacterial cellulose graft on the tympanic membrane compared to the conventional approach with autologous fascia. METHODS: Randomized controlled trial. Forty patients with tympanic membrane perforations secondary to chronic otitis media were included, and were randomly assigned to an experimental group (20), treated with a bacterial cellulose graft (BC) and control group (20), treated with autologous temporal fascia (fascia). We evaluated the surgical time, hospital stay, time of epithelialization and the rate of tympanic perforation closure. Hospital costs were compared. The statistical significance level accepted was established at p < 0.05. RESULTS: The closure of perforations was similar in both groups. The average operation time in the fascia group was 76.50 min versus 14.06 min bacterial cellulose in the group (p = 0.0001). The hospital cost by the Brazilian public health system was R$ 600.00 for the bacterial cellulose group, and R$ 7778.00 for the fascia group (p = 0.0001). CONCLUSION: Bacterial cellulose grafts promoted the closure of the tympanic membrane perforations, and were demonstrated to be innovative, effective, safe, minimally invasive, efficacious and to have a very low cost.


RESUMO INTRODUÇÃO: Tratamentos promissores para o fechamento da perfuração da membrana timpânica vêm sendo estudados. Terapias provenientes de engenharia de tecidos provavelmente eliminarão a necessidade de uma intervenção cirúrgica convencional. A celulose bacteriana apresenta-se como uma alternativa por ser segura, de baixa toxicidade, biocompatível. OBJETIVOS: Investigar o efeito da aplicação direta do enxerto da celulose bacteriana na cicatrização de perfurações da membrana timpânica, comparado ao procedimento convencional com fáscia autóloga. MÉTODO: Incluíram-se 40 pacientes com perfuração da membrana timpânica por otite média crônica simples. Randomizados de 1 a 40, onde os ímpares (20) foram tratados com enxerto de celulose bacteriana (CB), e os pares (20), com enxerto de fáscia temporal autóloga (fáscia). Estudo clínico controlado e randomizado. O tempo cirúrgico e de hospitalização foram o tempo de epitelização e custos hospitalares. RESULTADOS: O fechamento das perfurações foi semelhante nos dois grupos. O tempo médio da cirurgia no grupo fáscia foi de 76,50 minutos e de 14,06 minutos no grupo com celulose bacteriana (p = 0,0001). O custo hospitalar pela tabela do SUS foi de R$ 600,00 para o grupo CB e R$ 7.778,00 para o grupo fáscia (p = 0,0001). CONCLUSÃO: A celulose bacteriana promoveu o fechamento da perfuração do tímpano, mostrando-se inovador, seguro, eficaz, efetivo, minimamente invasivo e de baixo custo.

ABSTRACT

Temporomandibular joint ankylosis (TMA) is a highly distressing condition in which the temporomandibular joint (TMJ) is replaced by scar tissue. Most frequently reported complications after surgical treatment are limited mouth opening and re-ankylosis. Reankylosis happens due to inadequate bone removal, lack of sufficient interpositional material, fibrous tissue adhesions and elongation of coronoid process and regrowth of bone in the sigmoid notch area. In gap arthroplasty treatment chances to recurrence is 53% than interpositional arthroplasy. We treated a case of right sided TMJ reankylosis by interpositional arthroplasty with temporomyofacial flap and physiotherapy was started 3 days after surgery and maintained for 6 months. In 2 years follow-up, no signs of recurrence and maximum mouth opening 45 mm were observed. The success in preventing reankylosis after TMJ interpositional arthroplasty with temporomyofacial flap is relatively better than gap arthroplasty alone.

ABSTRACT

The definite cause of temporomandibular joint (TMJ) ankylosis is still an unknown fact. TMJ ankylosis may result from, infection, trauma or insufficient surgical treatment of the mandibular condyle region. Different techniques have been described so far for the treatment of TMJ ankylosis, but no technique has successfully given uniform results. Relapse causing limited mouth opening, infection, open bite, reankylosis are the complications. Many authors agree that aggressive physiotherapy immediately after the surgical procedure, interpositional graft as spacer and wide bone resection are the basic principles in treating TMJ ankylosis. In this article, we discussed a case of unilateral TMJ ankylosis, in a 9-year-old boy, treated with the intre-positional gap arthroplasty with superficial temporalis fascia flap.

ABSTRACT

The temporoparietal fascia flap has been extensively used in craniofacial reconstructions. However, its use for eyebrow reconstruction has been sporadically reported. We describe a successfully repaired hair-bearing temporoparietal fascia flap after traumatic avulsion of eyebrow. Temporoparietal fascia flap is a versatile tool and should be considered as a therapeutic option by all plastic surgeons.


O retalho de fáscia temporoparietal tem sido usado em inúmeras reconstruções craniofaciais. No entanto, sua utilização para a reconstrução de sobrancelha tem sido relatada esporadicamente. Descreve-se aqui o reparo com retalho de fáscia temporoparietal associado à ilha para a reconstrução de sobrancelha, após avulsão traumática, realizado com sucesso. O retalho de fáscia temporoparietal é uma ferramenta versátil e deveria ser considerada no arsenal terapêutico de todos os cirurgiões plásticos.

ABSTRACT

En este trabajo se presenta la serie de casos con lesión severa de la mano que requirieron de colgajos antebraquiales como parte de su tratamiento, así como su resultado funcional; se revisaron los expedientes clínicos de los pacientes con diagnóstico de lesión traumática de la mano, con grandes pérdidas de cobertura cutánea, a los que se les realizó algún colgajo de flujo reverso de antebrazo durante su reconstrucción. Se estudiaron las siguientes variables: tipo de colgajo, sexo, edad, mecanismo de lesión, zona receptora, tamaño, lesiones adyacentes y su tratamiento, prueba de integridad vascular previa a la realización del colgajo, tiempo quirúrgico, seguimiento y complicaciones. Se documentaron un total de 25 pacientes, con 25 colgajos fasciocutáneos de flujo reverso de antebrazo, 15 basados en arteria radial y 10 en arteria interósea posterior. Para los colgajos radiales (CR) se utilizó la prueba de Allen en 13 casos para verificar la integridad del arco palmar superficial; en los otros dos casos se realizó ultrasonido Doppler. En 16 casos (64%), se realizó reconstrucción osteotendinosa, tenorrafia aislada de uno o varios tendones en cuatro casos (16%), osteosíntesis aislada en dos (8%), oponen plastía de Littler en un caso por quemadura eléctrica con un colgajo radial en la cara anterior de la muñeca (4%) y colgajo en forma aislada en dos casos (8%). Tuvimos congestión y pérdida total del CIOP (4%) en un paciente de 67 años. Las indicaciones que se recomiendan para el CIOP son: la cobertura del tercio distal del antebrazo, dorso de mano y dedos, primer espacio interdigital, la región palmar de la muñeca y la mano. Sólo se tuvieron dos casos para cobertura en región palmar de la muñeca y la mano; y se solucionó con colgajos radiales en ambos casos, probablemente por comodidad anatómica...


This paper describes a series of cases with severe hand injury that required antebrachial flaps as part of treatment, and their functional results. The clinical records of patients with a diagnosis of traumatic hand injury and major skin cover losses, reconstructed with a reverse-flow forearm flap, were reviewed. The following variables were studied: type of flap, sex, age, mechanism of injury, receiver site, size, adjacent injuries and their treatment, vascular integrity test prior to flap placement, operative time, follow-up and complications. A total of 25 patients were included, with 25 reverse-flow fasciocutaneous forearm flaps; in 15 of them the blood supply was based on the radial artery and in 10 in the posterior interosseous artery. The Allen test was used in 13 cases of radial flaps (RF) to check the integrity of the superficial palmar arch; Doppler ultrasound was used in the remaining two cases. Sixteen cases (64%) underwent bone and tendon reconstruction, four cases (16%) isolated tenorrhaphy of one or several tendons, two cases (8%) isolated osteosynthesis, one case due to electrical burn underwent Littler opponensplasty with a radial flap in the anterior aspect of the wrist (4%), and in two cases (8%) an isolated flap was used. In one 67 year-old patient (4%) there was congestion and total loss of the posterior interosseous flap. The recommended indications for this type of flap are: coverage of the distal forearm, hand dorsum and fingers, first interdigital space, palmar region of the wrist and hand. Only two cases required coverage of the palmar region of the wrist and hand, and they were both treated with radial flaps, probably for reasons of anatomical convenience...

ABSTRACT

No tratamento dos pacientes vítimas de desenluvamento atendidos de maneira correta e precoce, a enxertia primária, com utilização da pele proveniente dos retalhos traumáticos é fundamental. Podem ser utilizados enxertos em ambas as espessuras, parcial ou total, não existindo na literatura uma definição em relação à melhor opção. Esta pele, também, pode ser utilizada de maneira imediata ou após conservação em banco de tecidos. Descrevemos neste artigo as principais técnicas para retirada de enxertos dos retalhos traumáticos.


Primary grafting using skin from traumatic flaps is essential in the correct and early treatment of patients with degloving injuries. Split- or full-thickness grafts can be used; however, the literature does not yet provide any indication of the best option. Moreover, this skin also can also be used immediately or after tissue bank storage. This report describes the main techniques for graft removal from traumatic flaps.

ABSTRACT

OBJETIVO: Analisar o emprego de técnicas de reconstrução imediata de vulva, pós-ressecção cirúrgica, com retalhos fasciocutâneos das faces medial e/ou posterior da coxa. MÉTODOS: Estudo de coorte transversal, retrospectivo, para análise do resultado da reconstrução cirúrgica imediata, com retalhos fasciocutâneos em nove pacientes submetidas à vulvectomia, no período de maio de 2009 a agosto de 2010. RESULTADOS: A média de idade foi 61 anos (variação 36 a 82 anos). Em 56% dos casos, o diagnóstico foi neoplasia intraepitelial vulvar (NIV) tipo usual. A vulvectomia radical foi realizada em 45% das pacientes, a vulvectomia simples em 33% e as ressecções amplas, em 22%. Foram confeccionados 11 retalhos fasciocutâneos, sendo 36,3% de transposições de retalho posterior de coxa, 18,2% de retalhos mediais de coxa, 18,2% de retalhos em avanço em V-Y, 18,2% de retalhos em avanço simples e 9,1% de rotação de retalho de região posterior de coxa. Não houve casos de perdas importantes dos retalhos confeccionados. CONCLUSÃO: Os retalhos fasciocutâneos de coxa são, atualmente, boas opções para a reconstrução imediata da vulva pós-ressecção oncológica devido à preservação da sensibilidade e da disponibilidade tecidual nas áreas doadoras. A associação do Cirurgião Plástico com o Ginecologista oferece tranquilidade às pacientes e determina bons resultados pós-operatórios.


OBJECTIVE: To analyze the use of immediate reconstruction techniques of the vulva after surgical resection, with fasciocutaneous flaps of the medial and/or posterior thigh. METHODS: We conducted a transversal, retrospective study to analyse the outcome of immediate surgical reconstruction with fasciocutaneous flaps in nine patients who underwent vulvectomy from May 2009 to August 2010. RESULTS: Mean age was 61 years (range 36-82). In 56% of cases, diagnosis was vulvar intraepithelial neoplasia (VIN), usual type. Radical vulvectomy was performed in 45% of patients, simple vulvectomy in 33% and wide resections in 22%. Eleven fasciocutaneous flaps were made, of which 36.3% were flap transpositions from the posterior thigh, 18.2% from the medial thigh, 18.2% were in advancement flaps, 18.2% simple advancement flaps and 9.1% flap rotation from the posterior thigh. There were no major losses of the flaps made. CONCLUSION: Thigh fasciocutaneous flaps are currently the best options for immediate reconstruction after resection of vulvar cancer due to the preservation of sensibility and tissue availability in the donor areas. The association of the Plastic Surgeon with the Gynecologist offers tranquility for patients and provides good postoperative results.

ABSTRACT

BACKGROUND: Dermatologic surgeons routinely harvest pedicled flaps at distance with an axial or random pattern to repair facial defects. These types of skin flaps are time-consuming and have high economic, social and personal costs. These drawbacks could be avoided with the introduction of a single-step transfer of free flaps to the recipient site, with microvascular anastomosis. OBJECTIVE: To demonstrate that better results are obtained with myocutaneous or fasciocutaneous free flaps and which one is more suitable in surgical dermatology. MATERIAL AND METHODS: We selected two patients of opposite sexes and similar ages who had undergone Mohs surgery to remove recurrent malignant tumors that were located in the upper cheek bordering the zygomatic zone. The woman was treated with a fasciocutaneous radial free flap and the man with a rectus abdominis free flap. RESULTS: Both patients had excellent immediate postoperative outcomes. Complications observed in the male patient were related to a previous pulmonary alteration. The fasciocutaneous radial free flap reconstruction was easier to perform than the rectus abdominis free flap; nevertheless, the radial free flap is very thin and, although the palmaris longus tendon is used, it does not yield enough volume, requiring later use of implants. In contrast, the rectus abdominis free flap transfers a wide flap with enough fat tissue to expand in the future. As for the cosmetic results regarding the donor site, the rectus abdominis free flap produces better-looking scars, since secondary defects of the palmar surface cannot be directly closed and usually require grafting - a situation that some patients do not accept. CONCLUSIONS: In surgical dermatology, each case, once the tumor has been extirpated, requires its own reconstructive technique. The radial free flap is suitable for thin patients who are willing to cover their arm with a shirt. The rectus abdominis free flap is best suited for obese ...


FUNDAMENTOS: Os cirurgiões dermatológicos habitualmente realizam retalhos pediculados cutâneos à distância, de padrão axial ou ao acaso, para reparar os defeitos faciais. Estes tipos de retalhos cutâneos requerem muito tempo para realizar-se e têm elevadas despesas econômicas, sociais e pessoais. Com a introdução da transferência em uma única etapa de retalhos livres ao local receptor, com anastomose microvascular, estes inconvenientes poderiam ser evitados. OBJETIVO: Demonstrar que se obtêm melhores resultados com retalhos livres fasciocutâneos ou miocutâneos e qual deles é mais adequado em Dermatologia cirúrgica. MATERIAL E MÉTODOS: Selecionamos dois pacientes, de sexos diferentes e idades similares, que haviam sido tratados com cirurgia de Mohs, para eliminar os tumores malignos recidivantes que se localizavam na parte superior das bochechas contatando com a zona zigomática. A mulher foi tratada com um retalho livre fasciocutâneo radial e o homem com um retalho livre do músculo reto do abdômen. RESULTADOS: Ambos os pacientes tiveram excelentes períodos pós-operatórios imediatos. As complicações observadas no homem foram relacionadas a uma alteração pulmonar prévia. O retalho fasciocutâneo radial livre foi mais fácil de realizar do que o do reto do abdômen; não obstante, o retalho livre radial é muito fino e, embora lhe seja incluído tendão do palmar, não proporciona suficiente volume razão pela qual requer a introdução posterior de implantes. Em contrapartida, o retalho livre do reto do abdômen transfere um largo retalho que tem suficiente tecido grasso para poder engordar no futuro. Quanto aos resultados estéticos da zona doadora, o retalho do reto do abdômen produz melhores cicatrizes, já que os defeitos secundários da superfície palmar do antebraço não podem ser fechados diretamente e requerem habitualmente a aplicação de um enxerto; situação que alguns pacientes não aceitam. CONCLUSÕES: Como sempre em Dermatologia cirúrgica, cada ...

ABSTRACT

Few studies has been done using guided bone regeneration in maxillary sinus defects. AIM: To assess the bone repair process in surgical defects on the alveolar wall of the monkey maxillary sinus, which communicates with the sinus cavity, by using collagen membranes: Gen-derm - Genius Baumer, Pro-tape - Proline and autologous temporal fascia. MATERIALS AND METHODS: In this prospective and experimental study, orosinusal communications were performed in four tufted capuchin monkeys (Cebus apella) and histologic analysis was carried out 180 days after. RESULTS: In the defects without a cover (control), bone proliferation predominated in two animals and fibrous connective tissue predominated in the other two. In defects repaired with a temporal fascia flap, fibrous connective tissue predominated in three animals and bone proliferation predominated in one. In the defects repaired with Gen-derm or Pro-tape collagen membranes there was complete bone proliferation in three animals and fibrous connective tissue in one. CONCLUSIONS: Surgical defect can be repaired with both bone tissue and fibrous connective tissue in all study groups; collagen membranes was more beneficial in the bone repair process than temporal fascia or absence of a barrier.


Poucos experimentos têm sido conduzidos utilizando o princípio da regeneração óssea guiada nas perfurações ósseas do seio maxilar. OBJETIVO: Avaliar o processo de reparo ósseo em defeitos cirúrgicos experimentais realizados na parede alveolar do seio maxilar, comunicando-se com a cavidade sinusal utilizando membranas de colágeno e fáscia temporal. MATERIAIS E MÉTODOS: Neste estudo prospectivo, experimental, foram realizados defeitos ósseos em paredes alveolares dos seios maxilares comunicando-se com as cavidades sinusais de quatro macacos pregos (Cebus apella) com membranas de colágeno Gen-derm - Genius Baumer, Pro-tape - Proline e fáscia temporal autóloga e análises histológicas após 180 dias. RESULTADOS: No defeito experimental sem cobertura com métodos de barreira predominou proliferação óssea em dois animais e nos outros dois, tecido conjuntivo fibroso; no grupo em que foi utilizado fáscia temporal predominou tecido conjuntivo fibroso em três animais e proliferação óssea em um animal; nos grupos com membranas de colágeno Gen-derm Pro-tape houve completa proliferação óssea em três animais e predomínio de tecido conjuntivo fibroso em um animal. CONCLUSÕES: Os defeitos cirúrgicos experimentais podem ser reparados, tanto por tecido ósseo como por tecido conjuntivo fibroso, e o uso de membranas de colágeno trouxeram benefícios ao processo de reparo ósseo.

ABSTRACT

To compare two different procedures, tension-free vaginal tape [TVT] and autologous rectus fascia sling, according to their medium-term subjective and objective outcomes and satisfaction rates in the treatment of urinary stress incontinence in women. One hundred women with type II urinary stress incontinence were randomized to be treated with either TVT or autologous rectus fascia sling. They were evaluated by means of a cough-induced stress test, 1-hour pad test, Incontinence Impact Questionnaire [IIQ], and urodynamic study. They were reevaluated postoperatively every 6 months, and the collected data of more than 1 year's follow-up were compared with preoperative assessments. All patients completed the full 6-month postoperative assessment. However, of the 100 patients, only 61 [25 in the TVT and 36 in the sling group] were followed for more than 1 year. Mean follow-up time was 38.5 and 40 months in the TVT and sling group, respectively. Objective cure was achieved in 22 [88%] of the TVT group and in 30 [83%] of the sling group [p = 0.78] using a cough-induced stress test, and in 76 and 75% of the women in the TVT versus sling group [p = 0.83], respectively, using a 1-hour pad test. Postoperative mean IIQ scores were 44.3 [range 35.5-61.5] and 48.5 [range 38.5-69.7] in the TVT versus sling group [p = 0.46]. Five [20%] and 11 [30%] of the TVT and sling group, respectively, reported some changes in the voiding pattern or posture at more than 1 year's follow-up. There is no significant difference between the TVT and autologous rectus fascia sling procedures in the treatment of urinary stress incontinence at medium-term follow-up. There were changes in the voiding pattern for patients in both groups at more than 1 year postoperatively, which were not evident at early follow-up

ABSTRACT

Se presenta nuestra serie clínica constituida por 14 pacientes de sexo masculino, portadores de Incontinencia Urinaria (IU) debido a vejiga neurogénica con falla esfinteriana, quienes luego de fracaso de tratamiento médico, fueron sometidos a tratamiento quirúrgico para mejorar su continencia, entre los años 1998 y 2006. La cirugía realizada consistió en elevar el cuello vesical con una cinta (Sling) de Fascia de músculo Recto Anterior, pasada por debajo del Cuello Vesical o Uretra Prostática y fijada a la aponeurosis del mismo músculo. En la mayoría de los casos, se realizó una Entero-Cistoplastía de ampliación(ECP) en el mismo acto quirúrgico. La complicación más frecuente, derivada del Sling, fue la estenosis uretral (2 casos). Se obtuvo un alto grado de satisfacción en cuanto a continencia: el 57 por ciento de los pacientes está completamente continente y el 21,5 por ciento se moja a grandes esfuerzos.


We report our experience in 14 consecutive male patients with urinary incontinence secondary to neurogenic bladder with sphincter deficiency. All patients underwent surgical management between 1998 and 2006. Surgery was indicated only after medical treatment failure. Anterior rectus fascia was used as a hammock to suspend the bladder neck by anchoring the fascia to the muscle’s aponeurosis. In most cases simultaneous augmentation cystoplasty was performed. Urethral stenosis was observed in 2 cases. Patient satisfaction was achieved in most cases with a 57 percent ofcomplete continence and 21.5 percent of minor stress incontinence.
