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

Clinical application of three-dimensional printed preformed titanium mesh combined with free latissimus dorsi muscle flap in the treatment of squamous cell carcinoma with skull defect in the vertex / 中华烧伤杂志

Objective: To explore the clinical effects of three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation in the treatment of wounds with skull defect after radical surgery of squamous cell carcinoma in the vertex. Methods: A retrospective observational study was conducted. From January 2010 to December 2019, 5 patients with squamous cell carcinoma in the vertex accompanied with skull invasion who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the Second Affiliated Hospital of Air Force Medical University, including four males and one female, aged 50 to 65 years. The original lesion areas ranged from 5 cm×4 cm to 15 cm×8 cm. The titanium mesh was prefabricated via three-dimensional technic based on the result the scope of skull resection predicted with computerized tomography three-dimensional reconstruction before surgery. During the first stage, the soft tissue defect area of scalp (8 cm×7 cm to 18 cm×11 cm) after tumor enlargement resection was repaired with the preformed titanium mesh, and the titanium mesh was covered with latissimus dorsi muscle flap, with area of 10 cm×9 cm to 20 cm×13 cm. The thoracodorsal artery/vein was anastomosed with the superficial temporal artery/vein on one side. The muscle ends in the donor site were sutured together or performed with transfixion, and then the skin on the back were covered back to the donor site. On the 10th day after the first-stage surgery, the second-stage surgery was performed. The thin intermediate thickness skin graft was taken from the anterolateral thigh to cover the latissimus dorsi muscle flap. The duration and intraoperative blood loss of first-stage surgery were recorded. The postoperative muscle flap survival after the first-stage surgery and skin graft survival after the second-stage surgery was observed. The occurrence of complications, head appearance, and recurrence of tumor were followed up. Results: The average first-stage surgery duration of patients was 12.1 h, and the intraoperative blood loss was not more than 1 200 mL. The muscle flaps in the first-stage surgery and the skin grafts in the second-stage surgery all survived well. During the follow-up of 6-18 months, no complications such as exposure of titanium mesh or infection occurred, with good shape in the recipient sites in the vertex, and no recurrence of tumor. Conclusions: Three-dimensional printed preformed titanium mesh combined with latissimus dorsi muscle flap free transplantation and intermediate thickness skin graft cover is an effective and reliable method for repairing the wound with skull defect after extended resection of squamous cell carcinoma in the vertex. This method can cover the wound effectively as well as promote both recipient and donor sites to obtain good function and appearance.

Patient satisfaction with breast reconstructionusing musculocutaneous flap from latissimus dorsiversus from rectus abdominis: a cross-sectional study

ABSTRACT BACKGROUND: Breast cancer is the second most frequent type of cancer worldwide and the most common type among women. The treatment for this condition has evolved over recent decades with therapeutic and technological advances. Breast reconstruction techniques using musculocutaneous flaps from the latissimus dorsi and rectus abdominis have aroused interest regarding patients' quality of life. Our goal here was to compare patients' satisfaction scores after they underwent breast reconstruction using musculocutaneous flaps from either the latissimus dorsi or the rectus abdominis. DESIGN AND SETTING: Primary, clinical, analytical, observational and cross-sectional study conducted in a federal university and a public hospital. METHODS: Demographic and clinical data were collected. The Mini-Mental State Examination was then applied, with testing for specificity and sensitivity. Lastly, a breast evaluation questionnaire was applied to evaluate breast satisfaction among 90 women, who were divided into three groups: mastectomy (control; n = 30); breast reconstruction using flap from the latissimus dorsi (n = 30); and reconstruction using flap from the rectus abdominis (n = 30). RESULTS: The groups were homogeneous regarding the main demographic data and the questionnaire responses (P < 0.05). Compared with the control group, the reconstruction groups showed significant improvement in satisfaction (P < 0.0002) after one year. CONCLUSION: Within our sample, women who underwent breast reconstruction with flaps from either the latissimus dorsi or the rectus abdominis had similar satisfaction scores.

INTRODUÇÃO: A reconstrução da parede torácica ainda permanece como um dos grandes desafios da cirurgia plástica reparadora. O presente estudo tem como objetivo apresentar o relato de pacientes submetidos à reconstrução de parede torácica com a utilização de retalhos miocutâneos, após ressecções de parede por tumores/osteomielite. MÉTODOS: Foram incluídos quatro pacientes, três deles portadores de osteomielite e o último apresentando-se com sarcoma, todas as afecções acometendo a parede torácica. Foram submetidos à ressecção de parede e reconstrução com retalhos miocutâneos do grande dorsal (dois casos) e reto abdominal (dois casos). RESULTADOS: Os retalhos utilizados foram suficientes para cobertura cutâneo-muscular e mantiveram boa vitalidade. Em apenas um caso, houve sofrimento parcial do retalho. Não houve recidiva precoce da doença. A estabilidade da caixa torácica foi preservada. CONCLUSÕES: A utilização dos retalhos citados no reparo dos defeitos torácicos mostrou-se satisfatória na intenção de prover revestimento cutâneo e músculo bem vascularizado, este fundamental no combate aos quadros infecciosos locais.

INTRODUCTION: Chest wall reconstruction remains one of the great plastic surgery repair challenges. The present work aims to report on cases of chest wall reconstruction using myocutaneous flaps after wall resection due to tumor/osteomyelitis. METHODS: Four patients were included, among which three presented with osteomyelitis and the other presented with sarcoma; both of these conditions affected the chest wall. Each patient underwent wall resection and reconstruction using myocutaneous flaps from the latissimus dorsi (two cases) and abdominal rectus (two cases). RESULTS: The flaps used were sufficient for skin-muscle covering and maintained good vitality. Partial flap injury occurred in one case. Chest cavity stability was preserved. CONCLUSIONS: The use of the above flaps to repair chest defects was satisfactory with the aim of covering the skin and providing well-vascularized muscles, the latter of which was fundamental to preventing local infection.

O estudo da representação anatômica do músculo latíssimo do dorso e a sua aplicação em cirurgia plástica / Anatomical representation of the latissimus dorsi and its application in plastic surgery

INTRODUÇÃO: O músculo latíssimo do dorso (MLD) é um importante elemento da parede látero-posterior do tórax. A aplicabilidade do MLD em cirurgia plástica é reconhecida por sua anatomia constante, sendo indicado, na reconstrução mamária, na microcirurgia, nas reconstruções de membros superiores, entre outros, tornando-se um retalho versátil em cirurgia reconstrutora. Sua representação em livros e estudos anatômicos apresentam controvérsias. Mathes & Nahai expressam que a posição do MLD é configurada em uma localização onde o músculo encontra-se em segmento torácico látero-posterior, mas com uma representação mais posterior que lateral. Um grande número de anatomistas escreve da mesma forma. O objetivo é o de discutir e descrever a real posição do MLD por meio do estudo da sua anatomia e comparação com imagens publicadas em livros. MÉTODOS: Estudou-se a descrição e representação anatômica do MLD em desenhos publicados em livros e artigos de autores clássicos. Os desenhos foram comparados com o estudo da anatomia vásculo-nervosa e muscular do MLD durante a dissecção, na posição de Decúbito Dorsal (DD), de 47 cadáveres frescos. RESULTADOS: O estudo da descrição e representação anatômica do MLD em livros de autores consultados, comparada com a dissecção em DD de cadáveres frescos, permitiu conhecer que estes autores identificam o MLD em uma posição mais posterior do que a encontrada na anatomia. CONCLUSÃO: Este estudo identifica a posição do MLD com uma representação mais anterior do que os desenhos dos livros estudados. A rotação e individualização do MLD com o paciente em decúbito dorsal é uma abordagem segura.

INTRODUCTION: The latissimus dorsi muscle (LDM) is an important element in the lateroposterior wall of the thorax. The LDM is valued in plastic surgery for its constant anatomy, and its use is recommended for mammary reconstruction, microsurgery, and upper limb reconstruction among other procedures, which makes it a versatile flap for reconstructive surgery. However, its representation in books and anatomical studies is controversial. Mathes & Nahai described that the position of the LDM is configured in a location where the muscle is found in the lateroposterior thoracic segment but with a more posterior than lateral representation. A great number of anatomists share the same opinion. The objective of this study was to discuss and describe the real position of the LDM through study of its anatomy and comparison with images published in books. METHODS: We studied the anatomical description and representation of the LDM in drawings published in books and articles by classical authors. The drawings were compared with the neurovascular and muscular anatomy of the LDM during its dissection from 47 fresh cadavers in the dorsal decubitus (DD) position. RESULTS: Study of the anatomical description and representation of the LDM in the revised books compared with the dissection of fresh corpses in the DD position revealed that the published authors described the LDM in a more posterior position than that found in the body. CONCLUSION: This study identified the LDM position as being more anterior than that described by drawings in published books. LDM rotation and individualization with the patient in a DD position is a safe approach.

A sistematização do retalho do músculo latíssimo do dorso em decúbito dorsal / The formation of the latissimus dorsi muscle flap in the dorsal decubitus position

Introdução: O músculo latíssimo do dorso localiza-se na parede latero-posterior do tórax. O retalho do músculo latíssimo do dorso (RMLD) tem uma extensa aplicabilidade devido a sua anatomia pouco variável contribuindo, assim, para sua utilização em Cirurgia Plástica. A possibilidade de dissecar este músculo em decúbito dorsal (DD) dispensa a mudança de posição do paciente e cria uma opção para reconstruções microcirúrgicas. Este estudo objetiva sistematizar a técnica utilizada para dissecção do RMLD em DD. Método: Foram avaliados 10 casos de RMLD realizados no Hospital Universitário da Universidade Federal de Alagoas, os procedimentos cirúrgicos de individualização dos retalhos e seu posicionamento na região receptora foram semelhantes nos dez casos. É realizada a avaliação do músculo e a demarcação do retalho com o paciente em pé. Depois, com o paciente em DD, faz-se a indução anestésica e a preparação do campo a ser operado. Faz a abordagem do pedículo vásculo-nervoso por incisão na margem superior da elipse que delimita o RMLD, secciona o tendão de inserção do músculo e retira-se o retalho necessário à área receptora a ser reconstruída. Resultados: A posição do paciente no intraoperatório foi o DD, inclusive durante a dissecação dos retalhos musculares, e a técnica utilizada não proporcionou desvantagens do ato cirúrgico. Conclusão: É possível realizar a dissecção e individualização do RMLD estando o paciente em DD.

Introduction: The latissimus dorsi muscle is located on the lateral-posterior chest wall. The latissimus dorsi muscle flap (LDMF) has extensive applications due to its consistent anatomy, which contributes to its use in plastic surgery. This muscle can be dissected in the dorsal decubitus (DD) position; this removes the need for a change in patient position and enables microsurgical reconstruction to be performed. This study aimed to describe the technique used for the dissection and transfer of the LDMF in the DD position. Method: We evaluated 10 cases of LDMF formation performed in the University Hospital of the Federal University of Alagoas. The surgical procedures of individualization of the flaps and their positioning in the receiver region were similar in all ten cases. The evaluation of the muscle and the demarcation of the flap were performed with the patient in the standing position. Then, with the patient in the DD position, anesthetic induction was initiated and the operating field prepared. The neurovascular pedicle was formed by incising the top edge of the ellipse that delimits the LDMF, dissecting the insertion tendon of the muscle, and removing the flap necessary for the reconstruction of the receiver area. Results: The patient was in the DD position during the intraoperative period, even during the dissection of muscle flaps, and the technique used had no surgical disadvantages. Conclusion: It is possible to perform the dissection and individualization of the LDMF with the patient in the DD position.

Utilização do retalho miocutâneo de grande dorsal, com extensão adiposa, nas reconstruções mamárias: uma opção para preenchimento do polo superior / Use of the myocutaneous latissimus dorsi flap with fat extension in breast reconstruction: an option for filling the upper pole

INTRODUÇÃO: As sequelas de mastectomia se apresentam de formas variadas exigindo, do cirurgião, experiência e criatividade para obter o melhor resultado na reconstrução de uma nova mama. Dentre as dificuldades para que este objetivo seja alcançado, está o desafio de um melhor preenchimento do polo superior da mama. O objetivo deste trabalho é apresentar uma opção terapêutica alternativa para correção do polo superior dentre as técnicas já existentes com este propósito. MÉTODO: A técnica cirúrgica utilizou o retalho de músculo grande dorsal com extensão gordurosa para preenchimento do polo superior da neomama durante sua reconstrução. A técnica descrita foi utilizada em 8 pacientes durante a reconstrução mamária tardia, com idades variando entre 39 e 70 anos. O tamanho desta extensão gordurosa variou entre 4,0 × 10,0 e 7,0 × 13,0 cm. O componente gorduroso do retalho foi avaliado após 3 meses através de ressonância magnética. RESULTADOS: Foram usados implantes mamários que variavam entre 270 e 435 ml. O acompanhamento pós operatório variou entre 3 meses a 1 ano. Ocorreram 2 casos de epidermólise (28%) na junção do retalho cutâneo com a área receptora. Não houve perda ou sofrimento do retalho. Os resultados demonstram clinicamente ou visualmente que a correção da depressão do polo superior da neomama foi alcançada adequadamente, bem como a viabilidade do retalho gorduroso, observada nos exames de imagem (ressonância magnética). CONCLUSÃO: A técnica proposta é uma alternativa adequada para o tratamento da maioria dos casos de reconstrução mamária em que se busca o preenchimento da depressão existente no polo superior da mama.

INTRODUCTION: The sequelae of mastectomy presents in numerous ways, requiring the experience and creativity of the surgeon to achieve the best result in the reconstruction of a new breast. One of the difficulties in achieving this objective is the challenge of adequately filling the upper pole of the breast. The objective of this work was to present an alternative therapeutic option for correction of the upper pole of the neobreast. METHODS: In our surgical technique, a latissimus dorsi muscle flap with fat extension is used for filling the upper pole of the neobreast during its reconstruction. The described technique was used in 8 patients during late breast reconstruction. The patients' ages ranged from 39 and 70 years. The size of the fat extension ranged from 4.0 × 10.0 cm to 7.0 × 13.0 cm. The fat component of the flap was evaluated after 3 months by using magnetic resonance imaging (MRI). RESULTS: Breast implants that varied in volume between 270 and 435 mL were used. The follow-up period after surgery ranged from 3 months to 1 year. Two patients had epidermolysis (28%) at the junction of the cutaneous flap and the receiver area. No graft loss or other complications occurred. Our results demonstrate clinically or visually that correction of the depression in the upper pole of the neobreast was satisfactorily achieved. The viability of the fat flap, as observed on MRI, was adequate. CONCLUSION: The proposed technique is a suitable alternative method for filling the depression in the upper pole of the neobreast in most cases of breast reconstruction.
