Anatomical classification of adductor magnus perforator flap and its application in head and neck reconstruction / 中华耳鼻咽喉头颈外科杂志

Objective: To investigate the anatomical classification of adductor magnus perforator flap and its application in head and neck reconstruction. Methods: From January 2017 to January 2020, Hunan Cancer Hospital treated 27 cases of oral tumor patients (15 cases of tongue cancer, 9 cases of gingival cancer and 3 cases of buccal cancer), including 24 males and 3 females, aged 31-56 years old. The course of disease was 1-12 months. Secondary soft tissue defects with the sizes of 5.0 cm × 3.5 cm to 11.0 cm × 8.0 cm were left after radical resection of the tumors, and were repaired with free adductor magnus perforator flaps. The flaps based on the origing locations of perforator vessels were divided into three categories: ① intramuscular perforator: vessel originated between the gracilis muscle and the adductor magnus or passed through a few adductor magnus muscles; ② adductor magnus middle layer perforator: vessel run between the deep and superficial layers of adductor magnus; ③ adductor magnus deep layer perforator: vessel run between the deep layer of adductor magnus and the semimembranous muscle. Descriptive analysis was used in this research. Results: Perforator vessels of adductor magnus were found in all cases, with a total of 62 perforator branches of adductor magnus. The anatomical classification of the perforator vessels was as follows: 12 branches for class ①, 31 branches for class ② and 19 branches for class ③. The vascular pedicles of the free adductor major perforator flaps included type ① for 3 cases, type ② for 16 cases and type ③ for 8 cases. All 27 flaps survived and the donor sites were closed directly. In 18 cases, the perforator arteries and the venae comitan were respectively anastomosed with the superior thyroid arteries and veins. In 9 cases, the pedicle arteries and the venae comitan were respectively anastomosed with the facial arteries and veins. Follow up for 12-40 months showed that the appearances of the flaps and the swallowing and language functions of patients were satisfactory, apart from linear scars were left in the donor sites with no significant affect on the functions of thigh. Local recurrence occurred in 3 cases and radical surgeries were performed again followed by repairs with pedicled pectoralis major myocutaneous flaps. Cervical lymph node metastasis occurred in 2 cases and cervical lymph node dissection was performed again. Conclusions: The adductor magnus perforator flap has soft texture, constant perforator vessel anatomy, flexible donor location and harvesting forms, and less damage to the donor site. It is an ideal choice for postoperative reconstruction in head and neck tumors.

Current practice: the bilobed flap from the classic indication to cover a small defect on face to covering a large defect on the chest

A variety of flaps are available to cover skin defects after surgery or trauma in the head and neck area. The bilobed flap is a double transposition flap commonly used in reconstruction of small-to-medium skin defects of the face where skin is less mobile. However, larger defects can also be effectively treated with a bilobed flap in certain cases. The classic indication to cover a small defect on the nose and covering a large skin-defect after tumour resection in the jugular notch. After sufficient mobilization, the defects could easily be closed with no wound complications and with very good aesthetic and functional outcome. The bilobed flap, as a local flap, is possible in suitable locations even for larger skin defects. In addition to the simplicity of the procedure, good aesthetic results can be expected

Estratégias em reconstruções complexas do couro cabeludo e da fronte: uma série de 22 casos / Strategies in complex reconstructions of the scalp and forehead: a series of 22 cases

INTRODUÇÃO: A região cefálica está exposta a insultos de ordem variada por parte do meio ambiente. As lesões extensas no couro cabeludo representam um grande desafio ao cirurgião plástico devido à pouca mobilidade da pele nesta região, o que dificulta o seu fechamento. Uma grande variedade de técnicas tem sido utilizada para o fechamento de defeitos no couro cabeludo e na fronte. A técnica ideal deve visar o melhor resultado funcional, estético e baixa morbidade do sítio doador. MÉTODOS: Foi realizado um estudo clínico retrospectivo no período de janeiro de 2006 a dezembro de 2014, de uma série de 22 casos com tumores avançados do couro cabeludo e da fronte e perda cutânea extensa pós-trauma. RESULTADOS: Foram realizados 11 retalhos locais de couro cabeludo (bi ou tripediculados), três retalhos coronais da fronte e oito retalhos livres. Houve um caso de perda parcial tardia de um retalho livre pós-radioterapia. CONCLUSÃO: Diferentes técnicas para a reconstrução do couro cabeludo e da fronte são possíveis, cada caso deve ser avaliado individualmente. Os retalhos apresentados foram considerados seguros e com pouca morbidade da área doadora. Os resultados obtidos foram satisfatórios e estão de acordo com a literatura analisada.

INTRODUCTION: The cephalic region is exposed to various insults from the environment. Extensive lesions in the scalp are a great challenge for plastic surgeons, because the low mobility of the skin in this region hampers its closure. A great variety of techniques have been used to close defects on the scalp and forehead. Ideally, scalp closure should provide a better functional and aesthetic outcome, as well as low morbidity at the donor site. METHODS: From January 2006 to December 2014, we performed a retrospective clinical study involving a series of 22 patients with advanced tumors of the scalp or forehead, or with extensive post-trauma skin loss. RESULTS: Reconstructive surgeries with 11 local scalp flaps (bi- or tri-pedicled), three coronal forehead flaps, and eight free flaps were performed. One patient experienced late partial loss of a free flap after radiotherapy. CONCLUSION: Various techniques can be used to reconstruct the scalp and forehead; each case should be assessed individually. The present study indicated that flaps are safe and that they confer low morbidity at the donor area. These results were satisfactory and in agreement with the literature analyzed.

Microsurgical head and neck reconstruction: retrospective analysis of 30 free flaps / Reconstrução microcirúrgica em cabeça e pescoço: análise retrospectiva de 30 retalhos livres

Introduction: Reconstructive head and neck surgery is a challenge for the plastic surgeon and requires a large technical arsenal, in which microsurgery plays an essential role. The objective to retrospectively analyze microsurgical head and neck reconstruction performed at the Pontifical Catholic University of Campinas over a period of 2 years. Methods: The medical charts of patients who underwent microsurgical reconstruction after head and neck surgery between June 2014 and October 2016 were reviewed to determine which flap was used, the length of the vascular pedicle, recipient vessels, microvascular anastomoses, surgical time, length of hospital stay, complications, and success rate. Results: Thirty microsurgical reconstructions were performed using 3 types of flaps: anterolateral thigh (n = 15), antebrachial radial (n = 8), and fibula (n = 7). Recipient vessels: facial artery (70%) and facial vein (50%), as 92.4% of microvascular anastomoses were end-to-end. The average operative time was 10.1 hours. The average length of hospital stay was 10.7 days. Two flaps were lost due to arterial thrombosis, resulting in a success rate of 93.3%. Conclusions: The microsurgical reconstructions were effective for the repair of complex defects as well as to partially restore the shape and function of the affected tissues. Complications were observed in less than 50% of the cases, although these presented with significant morbidity. The success rate was similar to that reported by major centers of reconstructive microsurgery. The learning curve is long, although it tends to improve with staff training and the acquisition of experience over time.

Introdução: Cirurgia reconstrutiva em cabeça e pescoço representa desafio ao cirurgião plástico e requer amplo arsenal técnico, no qual a microcirurgia figura papel essencial. O objetivo é analisar retrospectivamente as reconstruções microcirúrgicas em cabeça e pescoço realizadas na Pontifícia Universidade Católica de Campinas no período de dois anos. Métodos: Pacientes submetidos à reconstrução microcirúrgica após cirurgia de cabeça e pescoço, entre junho de 2014 e outubro de 2016, tiveram seus prontuários revisados para avaliação do retalho utilizado, comprimento do pedículo vascular, vasos receptores, anastomoses microvasculares, duração da cirurgia, tempo de internação, complicações e índice de sucesso. Resultados: Foram realizadas 30 reconstruções microcirúrgicas com três tipos de retalhos: anterolateral da coxa (n = 15), antebraquial radial (n = 8) e fíbula (n = 7). Vasos receptores: artéria facial (70%) e veia facial (50%), sendo que 92,4% das anastomoses microvasculares foram término-terminais. As cirurgias duraram, em média, 10,1 horas. O tempo médio de internação hospitalar foi de 10,7 dias. Houve perda de dois retalhos por trombose arterial, levando à taxa de sucesso de 93,3%. Conclusões: As reconstruções microcirúrgicas analisadas foram eficazes na reparação dos defeitos complexos, restaurando parcialmente forma e função dos tecidos acometidos. Foram observadas complicações em menos da metade dos casos, porém com morbidade elevada. O índice de sucesso foi semelhante ao de grandes centros de microcirurgia reconstrutiva. A curva de aprendizado é longa, mas tende a melhorar com o treinamento da equipe e aquisição de experiência ao longo do tempo.

What is the outcome 5 years after cervicoplasty? / O que muda no resultado de uma cervicoplastia 5 anos depois?

Introduction: An approach based on multiple anatomical structures and the use of different surgical strategies seems to achieve more lasting results in cervical rejuvenation surgery. Thus, extended cervicoplasty is an option with favorable results and low complication rates. However, little has been published regarding the durability of the results. This study aimed to objectively evaluate the long-term results obtained with extended cervicoplasty in difficult cases. Methods: Twenty patients, classified as having a "difficult neck," underwent extended cervicoplasty and were followed for 5 years. The results at 1- and 5-year post-operative follow-up were evaluated by eight plastic surgeons, using six objective criteria based on a theoretically ideal neck. The comparison of the results obtained at these time points was performed using a paired Student's t-test, with a level of significance of 5%. Results: There was no significant difference in five of the six items evaluated (p-value ranging from 0.137 to 1.000), in the comparison between the first and fifth postoperative years. Subhyoid depression displayed a significantly better mean score in the fifth evaluation year than that observed in the first year after surgery (p = 0.039): from 5.80 ± 0.25 points (mean ± standard error of the mean) in the first year, to 6.45 ± 0.30 points in the fifth postoperative year. Conclusion: Extended cervicoplasty is an important alternative in the treatment of the neck region, and even provides lasting results in difficult cases.

Introdução: A abordagem de múltiplas estruturas anatômicas e a utilização de diferentes estratégias cirúrgicas parece contribuir para a obtenção de resultados mais duradouros na cirurgia do rejuvenescimento cervical. Para isso, a cervicoplastia ampliada é uma opção com resultados agradáveis e baixos índices de complicações. A durabilidade dos resultados obtidos é, no entanto, pouco discutida na literatura. O objetivo desse estudo é avaliar objetivamente a manutenção dos resultados a longo prazo obtidos com a cervicoplastia ampliada aplicada em casos difíceis. Métodos: Vinte pacientes, classificadas como "pescoço difícil", foram submetidas à cervicoplastia ampliada e acompanhadas por 5 anos. Os resultados do pós-operatório de 1 e de 5 anos foram avaliados por oito cirurgiões plásticos, por meio de seis critérios objetivos vinculados a um teórico pescoço ideal. A comparação entre os resultados obtidos nestes momentos foi realizada por meio do teste t-student pareado, considerando um nível de significância de 5%. Resultados: Não houve diferença significativa em cinco dos seis itens avaliados (valor de p variando entre 0,137 a 1,000), na comparação entre o primeiro e o quinto ano de pós-operatório. A depressão subhioideia apresentou pontuação média na avaliação do quinto ano significativamente melhor do que aquela observada no primeiro ano após a cirurgia (p = 0,039), passando de 5,80 ± 0,25 pontos (média ± erro padrão da média) no primeiro ano, para 6,45 ± 0,30 pontos no quinto ano de pós-operatório. Conclusão: A cervicoplastia ampliada se valida como alternativa importante no tratamento da região cervical mesmo em casos difíceis, proporcionando a obtenção de resultados duradouros.

Reconstruções craniofaciais: ainda há espaço para os retalhos locorregionais? / Craniofacial reconstructions: is there still room for locoregional flaps?

Introdução: Os tumores avançados de cabeça e pescoço ainda têm elevada prevalência no Brasil. A reconstrução de um defeito resultante de ressecção craniofacial é um desafio para o cirurgião plástico. Os retalhos livres são a primeira escolha para essas reconstruções e os retalhos locorregionais têm sido utilizados em casos selecionados. O objetivo deste estudo é avaliar uma série de reconstruções com retalhos locorregionais em pacientes submetidos a ressecções oncológicas craniofaciais, demonstrando a aplicabilidade desses retalhos e o resultado final das reconstruções. Métodos: Foram avaliadas, retrospectivamente, quatro reconstruções craniofaciais com retalhos locorregionais de fronte e couro cabeludo. Os pacientes foram operados no Hospital das Clínicas da Universidade Federal de Pernambuco (HC-UFPE) e assinaram termo de consentimento permitindo a publicação científica de suas fotos e casos clínicos. Resultados: Todas as reconstruções foram bem sucedidas. Não ocorreram casos de infecção local ou meningite, necrose do retalho, fístulas liquóricas ou deiscências. As reconstruções com retalhos locorregionais apresentadas foram seguras e simples para reconstruir defeitos extensos em região craniofacial. Conclusões: Os cirurgiões plásticos podem realizar reconstruções complexas com estes retalhos, demonstrando que ainda há espaço para este tipo de reconstrução.

Introduction: Advanced tumors of the head and neck still have a high prevalence in Brazil. Reconstructing a defect resulting from a craniofacial resection is a challenge for the plastic surgeon. Free flaps are the first choice for these reconstructions, and locoregional flaps have been used in selected cases. The objective of this study was to evaluate a number of reconstructions with locoregional flaps in patients undergoing craniofacial oncologic resection, to demonstrate the applicability of these flaps and the end result of the reconstructions. Methods: We retrospectively studied four craniofacial reconstructions with locoregional flaps on the forehead and scalp. The patients were operated at the Clinical Hospital of the Federal University of Pernambuco. They signed a consent form allowing the scientific publication of their photographs and clinical case records. Results: All reconstructions were successful. There were no cases of local infection or meningitis, flap necrosis, liquor fistula, or dehiscence. Reconstructions with locoregional flaps were safe and simple to perform for extensive defects in the craniofacial region. Conclusions: Plastic surgeons can perform complex reconstructions with locoregional flaps, demonstrating that there is still room for this type of reconstruction.

Uso do retalho cérvico-submandibular transverso nas reparações de defeitos do terço médio da face / Use of a transverse submandibular cervical flap in the repair of defects of the middle third of the face

INTRODUÇÃO: As reparações de defeitos extensos do terço médio da face, ao necessitarem de grandes quantidades de pele e subcutâneo, tornam-se complexas. Buscando reduzir morbidade e associar bom resultado estético-funcional, Ariyan & McGrath e, posteriormente, Behan et al. propuseram reconstruções a partir de retalhos transversos cervicais e cérvico-submandibulares, respectivamente. Tais retalhos dispõem de boas quantidades de tecidos e baixa morbidade da área doadora. Os autores propõem e descrevem uma variante do retalho de Behan para reconstruções de grandes defeitos no terço médio de face. MÉTODOS: Foi realizado um estudo retrospectivo de 8 casos de reconstrução do terço médio da face pelo retalho cérvico-submandibular transverso, no período de junho de 2011 a dezembro de 2013. Os parâmetros analisados foram: resultados possíveis e complicações precoces e tardias. RESULTADOS: Foram operados 8 pacientes, com média de idade de 73,5 anos. Todos os pacientes apresentaram resultados estético-funcionais satisfatórios. Dentre as complicações precoces, 3 pacientes apresentaram congestão vascular na primeira semana com resolução espontânea e 1 apresentou fistula salivar consequente à ressecção tumoral. Em relação às complicações tardias, a retração cicatricial foi a complicação observada, manifestada por ectrópio (2 pacientes) e retração labial (1 paciente). CONCLUSÃO: O retalho cérvico-submandibular transverso randomizado e com pedículos axiais é mais uma opção para reconstruções de defeitos do terço médio da face.

INTRODUCTION: The need for large amounts of skin and subcutaneous tissue makes it complex to repair extensive defects of the middle third of the face. Aiming to reduce morbidity and attain good aesthetic-functional outcomes, Ariyan and McGrath and, subsequently, Behan et al. proposed reconstruction techniques that use transverse and submandibular cervical flap, respectively. Such flaps have fair amounts of tissue and are associated with low morbidity in the donor area. The present authors propose and describe a variant of the Behan flap for use in the reconstruction of large defects of the middle third of the face. METHODS: We conducted a retrospective study of 8 cases of reconstruction with transverse submandibular cervical flaps for defects of the middle third of the face, conducted between June 2011 and December 2013. The following parameters were analyzed: possible results, and early and late complications. RESULTS: Eight patients with a mean age of 73.5 years were included. All of the patients presented aesthetic-functional satisfactory results. Among the early complications, vascular congestion occurred in 3 patients in the first week with spontaneous resolution, and salivary fistula occurred after tumor resection in 1 patient. With regard to late complications, scar retraction was observed, manifested by either by ectropion (2 patients) or labial retraction (1 patient). CONCLUSION: Randomized transverse submandibular cervical flaps with axial pedicles may be considered as another option for reconstruction of defects of the middle third of the face.

Reconstruções microcirúrgicas em pacientes pediátricos: uma série de 12 casos / Microsurgical reconstructions in pediatric patients: a series of 12 cases

INTRODUÇÃO: A cirurgia plástica reparadora depara-se com defeitos dos mais variados portes e localizações. O advento da microcirurgia possibilitou a reconstrução de defeitos complexos e extensos em um único estágio e com menor morbidade. Apesar de ter sido uma das primeiras aplicações da microcirurgia, a reconstrução pediátrica microcirúrgica só teve grandes series publicadas recentemente. MÉTODO: No período de janeiro de 2007 a dezembro de 2014 foram operados 12 pacientes consecutivos de reconstruções microcirúrgicas pós-ressecção de neoplasias em cabeça e pescoço e traumas complexos em membros de pacientes pediátricos. Os prontuários foram revisados retrospectivamente quanto à localização e etiologia das lesões, tipos de retalhos e complicações. RESULTADOS: Foram realizados 13 retalhos para a reconstrução microcirúrgica em 11 pacientes e uma revascularização microcirúrgica do braço, sendo cinco (41,7%) casos reconstruções pósressecção de neoplasias de cabeça e pescoço e sete (58,3%) casos pós-trauma complexos de extremidades. A taxa de viabilidade no nosso estudo foi de 84,6% dos retalhos realizados. CONCLUSÃO: A reconstrução microcirúrgica em crianças tem particularidades. Nossa experiência inicial e a literatura mostram resultados gratificantes neste grupo especifico de pacientes, o que torna este tipo de reconstrução nessa faixa etária factível e com uma alta taxa de sucesso.

INTRODUCTION: Reconstructive plastic surgery is used to treat defects of different sizes and locations. The advent of microsurgery has enabled the single-stage reconstruction of complex and large defects with lower morbidity rates. Despite being one of the first microsurgery applications, large pediatric microsurgical reconstruction series have been published only recently. METHOD: Between January 2007 and December 2014, 12 consecutive patients underwent microsurgical reconstruction upon the removal of head and neck tumors or complex trauma in the limbs of pediatric patients. The medical records were retrospectively reviewed for injury location and etiology, flap type, and complications. RESULTS: A total of 13 flaps were created for microsurgical reconstruction, including reconstruction upon head and neck tumor removal in five, limb complex post-trauma reconstruction in seven, and a microsurgical revascularization in the arm of one child. CONCLUSION: Microsurgical reconstruction in children is peculiar. Our initial experience and the studies published in the literature to date show that in this particular group of patients, it is possible to achieve rewarding results that render this type of reconstruction feasible and highly successful in this age range.

Head positioning for anterior circulation aneurysms microsurgery / Posicionamento da cabeça para microcirurgias de aneurismas da circulação anterior

Objective To study the ideal patient's head positioning for the anterior circulation aneurysms microsurgery. Method We divided the study in two parts. Firstly, 10 fresh cadaveric heads were positioned and dissected in order to ideally expose the anterior circulation aneurysm sites. Afterwards, 110 patients were submitted to anterior circulation aneurysms microsurgery. During the surgery, the patient's head was positioned accordingly to the aneurysm location and the results from the cadaveric study. The effectiveness of the position was noted. Results We could determine mainly two patterns for head positioning for the anterior circulation aneurysms. Conclusion The best surgical exposure is related to specific head positions. The proper angle of microscopic view may minimize neurovascular injury and brain retraction. .

Objetivo Estudar o posicionamento da cabeça para a cirurgia de aneurismas cerebrais da circulação anterior. Método Dividimos o estudo em duas partes. Inicialmente, dez cabeças de cadáveres frescos foram posicionadas e dissecadas de modo a expor, de maneira ideal, os principais sítios de aneurismas na circulação anterior do cérebro. Posteriormente, 110 pacientes foram submetidos a microcirurgia para clipagem de aneurismas cerebrais da circulação anterior. Durante as cirurgias, as cabeças foram posicionadas de acordo com a localização específica de cada aneurisma e o resultado obtido no estudo dos cadáveres. Cada paciente teve sua posição avaliada quanto a sua eficácia. Resultados Obtivemos basicamente dois padrões de posicionamento da cabeça para cirurgias de aneurismas cerebrais da circulação anterior. Conclusão A melhor exposição cirúrgica está relacionada à posição específica da cabeça para cada localização aneurismática. O ângulo de visão microscópica adequado minimiza lesões neurovasculares e a excessiva retração cerebral. .

Retalho miocutâneo inferior pediculado do músculo trapézio nas reconstruções após cirurgias oncológicas de cabeça e pescoço, e tórax / Lower trapezius myocutaneous pedicle flap in head, neck, and chest reconstructions after cancer surgeries

INTRODUÇÃO: Revisão da literatura sobre o retalho miocutâneo inferior do músculo trapézio, apresentando suas vantagens, técnica cirúrgica e complicações. MÉTODOS: Estudo de 19 casos tratados no INCA, através de técnica específica, e comparação dos dados com a literatura internacional. RESULTADOS: Todas as reconstruções atingiram seus objetivos, com correção dos defeitos em partes moles e pele. O efeito estético foi considerado bom pelos pacientes e pela equipe médica. Foi observada uma taxa de 21% de complicações. Não houve necrose ou infecção nos retalhos. Em relação às funções, 89,5% apresentaram função motora preservada e 10,5%, déficit funcional por acometimento tumoral do nervo acessório. CONCLUSÃO: A despeito do aprimoramento contínuo das técnicas microcirúrgicas, os retalhos miocutâneos pediculados ainda encontram indicações nas reconstruções após ressecções oncológicas alargadas. O retalho miocutâneo inferior do músculo trapézio é uma alternativa segura e aplicável para as reconstruções de partes moles das regiões cervicais lateral e posterior, da região lateral da cabeça, da região do ombro e para as regiões paraespinhal superior e paraescapulares.

INTRODUCTION: In this article, we present a literature review on the lower myocutaneous trapezius flap, and report its advantages, surgical technique, and complications. METHODS: We studied 19 patients treated at INCA with a specific technique, and compared the outcomes with those reported in the international literature. RESULTS: All reconstructions achieved the procedural objectives, and the defects of soft tissues and skin were repaired. The aesthetic outcome was considered satisfactory by the patients and medical staff. The rate of complications was 21%. No necrosis or signs of infection were detected in the flaps. Concerning the functions, 89.5% of patients preserved their motor function, whereas reduced functional movements were observed in 10.5% of the patients due to tumor invasion to the accessory nerve. CONCLUSIONS: Despite the continuous advancements in microsurgical techniques, pedicle myocutaneous flaps are still indicated for reconstruction procedures after extended cancer resections. The use of the lower trapezius myocutaneous flap is safe and represents a suitable option for the reconstruction of soft tissues of the lateral and posterior cervical regions, side of the head, shoulder, and upper paravertebral and parascapular regions.

Retrospective study on the effectiveness and indications of different types of flaps used for reconstruction of head and neck

Defects following head and neck surgery can be closed by direct closure when the defect is small, and where local conditions dictate that there is enough lax tissue. Flowever, for larger defects or in situations when direct suture is not applicable, surgical defects may be filled by free grafts, local flaps, pedicled flaps which may be either axial or musculocutaneous, or by using free tissue transfer. This study was conducted in attempt to clarify the success rate of different types of flaps in common use for head and neck reconstruction, the effectiveness of different flaps in terms of functional and esthetic results and which flap is the best for certain defects in head and neck region. In this retrospective study, among the patients with head and neck cancer treated in The Department of Otorhinolaryngology, Head and Neck Surgery, Hiroshima University, in the period from Jan.2004 to Dec.2009, patients whom post ablative defects needed to be reconstructed by flaps were only included. Patients whom defects were repaired either without flaps or by other means of reconstruction [e.g. gastric pull up] were excluded. The flaps among this study were compaired in terms of flap survival and functional outcomes [speech intelligibility, early starting of oral intake and cosmetic appearance]. This study was conducted upon 38 patients, they were 9 [23.68%] females and 29 [76.31%] males with a mean of age of 61 years [range 36- 84 years]. According to the site of the defect needed to be reconstructed after ablation of the primary lesion, patients were divided into three groups: 1-Patients with defects in the oral cavity and oropharynx which resulted from resection of malignant tumors involving or extending into oral cavity and oropharynx [26 patients] [Gl]. 2-Patients with defects in the hypopharynx which resulted from resection of cancer involving the hypopharynx [8 patients] [G2]. 3- Patients with post maxillectomy defects following resection of sinonasal cancer [4 patients] [G3]. In this study all defects resulted from resection of primary lesions were reconstructed immediately after ablation. As regarding patients with oral and oropharyngeal defects [n-26], the most common flap that was used in reconstruction was the pectoralis major myocutaneous flap [PMMF], that was used in ten patients followed by the radial forearm fasciocutaneous free flap that was used in seven patients, transverse rectus abdominas myocuianeous [TRAM] flap that was used in four patients, the fibula osseocutaneous free flap that was used in three patients and lastly the scapula free flap which was used in two patients. For hypopharyngeal defects [n=8], reconstruction was done in all patients with the free jejunal flap except in a single patient that was performed with the pectoralis major myocutaneous flap. In patients with craniosinonasal defects [n4], the TRAM flap was used in four patients to seal the oro-riasal communication and-the fascia lata for reconstruction of the anterior skull base defects. Overall evaluation of different types of flaps for reconstruction of head and neck defects revealed that radial forearm free flap and PMMF is the best two choices in terms of flap survival and functional outcome for reconstruction of oral cavity defects, free jejunal flap gave fair results for reconstruction of the hypopharynx and finally the TRAM flap isn't the best choice for reconstruction of the maxillary defects. Radial forearm free flap and pectoralis major myocutaneous flap [PMMF] are the best choice for reconstruction of oral cavity defects

Reconstrução microcirúrgica em cabeça e pescoço: análise retrospectiva de 60 retalhos livres / Head and neck microvascular reconstruction: retrospective analysis of 60 free flaps

The microsurgical reconstruction of the head and neck usually is the first indication for high tissue losses. The surgical team should have a hand full of technical options for any such loss. In addition, knowing how to manage each complication is importante. the aim of this study was to evaluate possibilites of reconstruction and complications in patients submitted to reconstruction using free flaps. Methods: A retrospective study of patients with loss of tissue in the head and neck, and submittedd to immediate or delayed microsurgical reconstruction was performed between March 2010 and March 2012. Results: Sixty patients that received free flaps, submitted to surgery between March 2010 and 2012, were analyzed. Of these, 31(52.7 %) patients were women and 39 (65.0%) Caucasians.Immediate reconstruction was performe in 65 % of the cases. Malignant tumourus were the most common diagnoses, representig 86.7 % of the cases. The frequency of the flaps was as follows: fibula in 36.7 % of the cases, rectus abdominais in 23.3 %, anterolateralthing in 23.3 %, antebrachial in 11.7 % and latissimus dorsi in 5 %. The average operative time was 8.6+_ 2.1 hours. The ischemia period was 107.5+_27.6 minutes. Complications were observed in 45 % of the cases: dehiscence in 18.3%, salivar fistula in 16.7 %, infection in 16.7 %, death during the first week after surgery in 5 %, and extrusion of the synthesized material in 1.7 %. Among the 60 flaps, a reintervention was required in 20 (33.3 %), and the loss of 13 (21.7 %) reconstructions occurred. The venous thrombosis was the main cause of reitervention and loss. Six salvage flaps were performed, three of the pectoralis pedicle and three of the latissimus dorsi muscle; two of the situations; wehen well succeded, they promote a decrease of morbidity, a promotion of rehabilitation, and a decrease in costs.

A reconstrução microcirúrgica de cabeça e pescoço costuma ser a primeira indicação para grandes perdas teciduais. A equipe cirúrgica deve ter um arsenal de opções técnicas para qualquer dessas perdas. Além disso, é importante conhecer o manejo de cada complicação. O objetivo deste estudo é avaliar as condutas de reconstrução e as complicações de paciente submetidos a reconstruções com retalhos livres. Método: Foi realizado estudo retrospectivo de pacientes com perda de substância em cabeça e pescoço, submetidos a reconstruções microcirúrgicas imediatas ou tardias, no período de março de 2010 a março de 2012. Resultados: Foram analisados 60 pacientes que receberam retalhos livres, dos quais 31 (52,7%) eram mulheres e 39 (65%), caucasianos. As reconstruções foram imediatas em 65% dos casos. Os tumores malignos foram o diagnostico mais comum, representando 86,7% dos casos. A frequência dos retalhos foi a seguinte: fibula, em 36,7% dos casos; reto abdominal, em 23,3%; ântero-lateral da coxa em 2,3%; antebraquial, em 11,7%; e grande dorsal, em 5%. O tempo cirúrgico médio foi de 8,6 ± 2,1 horas . O tempo de isquemia foi de 107,5 ± 27,6 minutos. Foram observadas complicações em 45% dos casos: deiscências em 18,3%, fístula salivar em 16,7%, infecção em 16,7%, óbito na primeira semana pós-operatória em 5%, e extrusão de material de síntese em 1,7%. Do 60 retalho houve reintervenção em 20 (33,3%) e perda de 13 (21,7%) reconstruções. A trombose venosa foi a causa mais comum de reintervenção e de perda. Foram realizados 6 retalhos de resgate, 3 de peitoral pediculado 3 d músculo grande dorsal, sendo 2 microcirúrgicos. Conclusões: Os retalho microcirúrgico têm grande importância em reconstrução de cabeça e pescoço, podem ser superiores aos pediculados na maioria das situações, e determinam, quando bem-sucedidos, diminuição da morbidade, aceleração da reabilitação e diminuição de custos.

Tratamento de queimadura de segundo grau superficial em face e pescoço com heparina tópica: estudo comparativo, prospectivo e randomizado / Treatment of superficial second degree burn of face and neck with topical heparin: a comparative, prospective and randomized study

INTRODUÇÃO: Novas opções terapêuticas para o tratamento de lesões térmicas são constantemente buscadas, especialmente se reduzirem tempo de cicatrização e dor, sem aumentar as taxas de infecção das queimaduras. Estudos recentes sugerem que o uso tópico de heparina pode alcançar esses objetivos. Este estudo tem o objetivo de avaliar tempo de epitelização, dor e taxa de infecção, comparando o uso de heparina tópica ao uso de colagenase no tratamento de queimadura de segundo grau superficial de face e pescoço. MÉTODO: No total, 20 pacientes foram randomizados em dois grupos: grupo tratado com heparina sódica e grupo tratado com colagenase (controle). Os critérios de exclusão foram: história de sangramento, discrasia sanguínea, alergias ao produto, úlcera péptica ativa e queimadura há mais de 24 horas. O teste de Mann-Whitney foi utilizado para avaliar os resultados. A dor foi avaliada pela necessidade do uso de analgésicos opioides. RESULTADOS: A heparina não foi efetiva em diminuir o tempo de epitelização ou o uso de opioides, e a taxa de infecção não apresentou diferença estatística entre os grupos. CONCLUSÕES: A heparina pode ser usada com segurança no tratamento de queimadura de segundo grau superficial em face e pescoço, mas seus efeitos benéficos ainda precisam ser comprovados.

BACKGROUND: New treatment options for thermal injuries are very desirable, especially if they reduce healing time and pain without increase of infection rates. Recent studies suggest that heparin topical use can achieve those goals. This study has the objective to evaluate healing time, pain and infection rate comparing topical use of heparin and collagenase in the treatment of superficial second degree burns of face and neck. METHODS: Twenty patients were randomized into 2 groups: group treated with topical heparin and group treated with collagenase (control group). The exclusion criteria were: history of bleeding, blood discrasia, allergies to the product, active peptic ulcer and burns with more than 24 hours. Mann-Whitney test was applied to evaluate the results. The pain was measured by the use of opioid analgesics. RESULTS: The heparin was not effective in decrease of healing time nor the use of opioids, and the infection rate didn't present significant difference between the groups. CONCLUSIONS: The heparin can be used safely in treatment of superficial second degree burn of face and neck, but its beneficial effects need to be proven.

Pectoralis major myocutaneous flaps for head and neck reconstruction: factors influencing occurrences of complications and the final outcome / Retalho miocutâneo de peitoral maior em reconstruções de cabeça e pescoço: fatores que influenciam a ocorrência de complicações e o resultado final

CONTEXT AND OBJECTIVE: Pedicled flaps play an important role in cancer treatment centers, particularly in developing and emerging countries. The aim of this study was to identify factors that may cause complications and influence the final result from reconstructions using pectoralis major myocutaneous flaps (PMMFs) for head and neck defect repair following cancer resection. DESIGN AND SETTING: Cross-sectional study at the Hospital de Ensino Padre Anchieta of Faculdade de Medicina do ABC (FMABC). METHODS: Data on 58 patients who underwent head and neck defect reconstruction using PMMFs were reviewed. The final result from the reconstruction (success or failure) and the complications observed were evaluated in relation to the patients' ages, area reconstructed, disease stage, previous oncological treatment and need for blood transfusion. RESULTS: There were no total flap losses. The reconstruction success rate was 93.1 percent. Flap-related complications occurred in 43.1 percent of the cases, and half of them were considered major. Most of the complications were successfully treated. Defects originating in the hypopharynx were correlated with the development of major complications (p = 0.02) and with reconstruction failure (p < 0.001). Previous oncological treatment negatively influenced the reconstruction success (p = 0.04). CONCLUSIONS: Since the risk factors for developing major complications and reconstruction failure are known, it is important to heed the technical details and provide careful clinical support for patients in a more critical condition, so that better results from using PMMFs can be obtained.

CONTEXTO E OBJETIVO: Retalhos pediculados têm grande importância nos centros de tratamento do câncer, principalmente em países emergentes e em desenvolvimento. O objetivo deste trabalho foi identificar fatores que determinam complicações e influenciam no resultado final das reconstruções com retalho miocutâneo de peitoral maior (RMPM) no reparo de defeitos cirúrgicos por ressecções de cânceres de cabeça e pescoço. TIPO DE ESTUDO E LOCAL: Estudo transversal no Hospital de Ensino Padre Anchieta da Faculdade de Medicina do ABC. MÉTODOS: Dados de 58 pacientes submetidos a reconstruções de defeitos de cabeça e pescoço com RMPM foram revisados. O resultado final da reconstrução (sucesso ou falha) e as complicações observadas foram avaliados de acordo com a idade do paciente, área reconstruída, estágio da doença, tratamento oncológico prévio e necessidade de transfusão sanguínea. RESULTADOS: Não houve perda total de retalho. A taxa de sucesso da reconstrução foi de 93,1 por cento. Complicações relacionadas ao retalho ocorreram em 43,1 por cento dos casos e 50 por cento delas foram considerados como complicações maiores. A maioria das complicações foi tratada com sucesso. Os defeitos originados da hipofaringe relacionaram-se com o desenvolvimento de complicações maiores (p = 0,02) e falhas na reconstrução (p < 0,001). Tratamento oncológico prévio influenciou negativamente no sucesso da reconstrução (p = 0,04). CONCLUSÕES: Como os fatores de risco para o desenvolvimento de complicações maiores e de falha na reconstrução são conhecidos, é importante atentar para detalhes técnicos e empregar suporte clínico cuidadoso aos pacientes mais críticos para que sejam obtidos melhores resultados com o uso do RMPM.

Retalhos miocutâneos de músculo peitoral maior: resultados e complicações em uma série de 116 casos / Myocutaneous flap of pectoralis major muscle: results and complications in a serie of 116 cases

Introdução: Os retalhos miocutâneos representam uma importante arma com que conta o cirurgião plástico quando se depara com grandes defeitos a serem cobertos após ressecção de tumores. Objetivo: O presente estudo tem por objetivo relatar a incidência de complicações com o uso de retalhos miocutâneos de músculo peitoral maior para reconstrução em cirurgia oncológica, em especial de cabeça e pescoço. Método: Foi realizado um estudo retrospectivo. Foram estudados pacientes operados por lesões malignas de cabeça e pescoço,nos quais se usou a técnica em discussão. Resultados: Foram avaliados 116 pacientes operados no período entre março de 1994 e julho de 2009. Houve 2 perdas totais de retalho,14 perdas parciais e formação de 17 fístulas. Conclusão: A incidência de complicações foi relativamente alta, o que relacionamos com o avançado estádio de doença dos pacientes operados e estado nutricional dos mesmos, além do porte das cirurgias. Apesar disso, os autores consideram o retalho miocutâneo de músculo peitoral maior um grande aliado parao cirurgião plástico que trabalha em reconstrução de cabeça e pescoço.

Introduction: The myocutaneous flap is an important tool on which the plastic surgeon relies when handling major defects after tumors resection. Purpose: The objective of this study is reporting the incidence of post-operative complications with myocutaneous flap of pectoralis muscle for repairs in oncologic surgery, especially head and neck. Methods: A retrospective survey was performed. Patients with head and neck malignancies submitted to this technique were studied. Results: Between March/1994 and July/2009, 116 patients submitted to oncologic surgery were evaluated. There were 2 total flap losses, 14 partial flap losses and 17 fistulas. Conclusion: The incidence of surgical complications was relatively high, what we believe to be linked with the advanced oncologic disease stage in our population, their nutritional condition and the nature of the surgery. Despite that, the authors consider that the myocutaneous flap of pectoralis muscle is a good choice for plastic surgeons working in head and neck reconstruction.
