    软组织肉瘤(STS)是间充质细胞起源的罕见实体瘤,仅占成人恶性肿瘤的1%。它们往往最常见于下肢。肉瘤切除术后的重建可能具有挑战性,特别是当涉及到重要的结构并且发生复发时。此外,现在越来越重视重建淋巴系统以防止淋巴并发症。在这个案例报告中,我们介绍了复发性大腿内侧肉瘤的治疗方法,该方法需要进行多种具有挑战性的重建,以便为类似病例的讲座提供有价值的见解。一名50岁的男性患者被诊断为大腿前内侧未分化的多形性细胞肉瘤(UPS)。术前放疗后,取出一块23×15厘米的肿块,并使用带蒂的深腹壁下动脉穿支(p-DIEP)皮瓣进行了重建。六个月后,患者首次出现局部复发,并伴有远处转移。肿瘤切除后,DIEP皮瓣的内侧部分被去上皮并埋在缺损中以消除死腔。第二次手术后7个月又出现局部复发。因此,进行了一项涉及股神经血管束的大型减缩手术.用合成移植物重建了股动脉,股静脉和对侧大腿大隐静脉。使用对侧大腿的复合肌皮神经化前外侧大腿(ALT)皮瓣消除缺损并恢复股四头肌功能的丧失。在脚踝处进行了两次淋巴静脉吻合(LVA),以降低淋巴后遗症的风险。本病例报告强调了整合各种技术以创建量身定制的方法的重要性,该方法有效地解决了复杂的手术要求,以避免截肢并保持功能。
    Soft-tissue sarcomas (STS) are rare solid tumors of mesenchymal cell origin and account for only 1% of adult malignancies. They tend to occur most commonly in the lower extremities. Reconstruction after sarcoma resection can be challenging, especially when important structures are involved and recurrences occur. Additionally, more attention is now being paid to reconstructing the lymphatic system to prevent lymphatic complications. In this case report, we presented the management of recurrent medial thigh sarcoma that necessitated multiple challenging reconstructions to provide valuable insights for lectures on similar cases. A 50-year-old male patient was diagnosed with an undifferentiated pleomorphic cell sarcoma (UPS) of the anteromedial thigh. After preoperative radiotherapy, a mass of 23 × 15 cm was removed, and reconstruction with a pedicled deep inferior epigastric artery perforator (p-DIEP) flap-based lymphatic flow through (LyFT) was performed. Six months later, the patient developed the first local recurrence with the presence of a distant metastasis. Following the tumor resection, the medial part of the DIEP flap was de-epithelized and buried in the defect for dead space obliteration. Another local recurrence arose 7 months after the second surgery. Therefore, a major debulking surgery involving the femoral neurovascular bundle was performed. The femoral artery was reconstructed with a synthetic graft, and the femoral vein with the great saphenous vein harvested from the contralateral thigh. A composite myocutaneous neurotized anterolateral thigh (ALT) flap from the contralateral thigh was used to obliterate the defect and restore the loss of function of the quadriceps femoris. Two lymphaticovenular anastomoses (LVAs) were performed at the ankle to reduce the risk of lymphatic sequelae. This case report highlights the importance of integrating various techniques to create a tailored approach that effectively addresses complex surgical requirements to avoid limb amputation and maintain functionality.

    穿孔器是穿过肌肉并灌注皮肤的血管。穿支皮瓣需要肌内解剖,可用作带蒂或游离皮瓣。随着对微血管系统的了解的提高,它们可以被定制为具有多个皮肤桨,多个组件,或成形以适应任何缺陷。可靠的穿支皮瓣重建是一种细致的微血管技术,最终允许外科医生以自由式方式收获任何皮瓣并移植到任何受体血管。新技术提高了这种重建的安全性和可重复性。
    A perforator is a vessel that travels through muscle and perfuses the skin. Perforator flaps require intramuscular dissection and can be used as pedicled or free flap. With improved understanding of microvasculature, they can be tailored to have multiple skin paddles, multiple components, or shaped to conform to any defect. Reliable perforator flap-based reconstruction is a meticulous microvascular technique, ultimately allowing the surgeon to harvest any flap in a freestyle fashion and transplant to any recipient vessel. New technologies improve the safety and reproducibility of this type of reconstruction.

    Tessier10号裂口是最罕见的面部裂口之一。由于眶周和颞部软组织畸形的复杂性,这种类型的裂口的手术治疗具有挑战性。一名23岁的男性患者表现为典型的Tessier10裂面部畸形。外科手术涉及使用游离的股前外侧皮瓣重建眼窝,颞浅动脉蒂头皮皮瓣用于重建眉毛畸形。患者无并发症,术后16个月,患者有良好的美学效果。带有颞浅动脉额支蒂的带毛头皮皮瓣与大腿前外侧游离皮瓣相结合,可以有效解决Tessier10号裂隙的大多数软组织畸形,并在一次手术中重建眶窝。同时,它增加额颞区的软组织,并提供良好的美学效果。
    Tessier number 10 cleft is one of the rarest facial clefts. Surgical treatment of this type of cleft is challenging due to the complexity of periorbital and temporal soft tissue deformities. A 23-year-old male patient presented with typical facial deformities of Tessier number 10 cleft. The surgical procedure involved using a free anterolateral thigh flap to reconstruct the eye socket, while the superficial temporal artery pedicle scalp flap was used to reconstruct the eyebrow deformity. The patient had no complications and 16 months after surgery, the patient had good aesthetic results. A hair-bearing scalp flap with a pedicle of the frontal branch of the superficial temporal artery combined with an anterolateral thigh-free flap can effectively resolve most soft tissue deformities of Tessier number 10 cleft and reconstruct the orbital socket in a single surgery. At the same time, it augments the soft tissue of the frontotemporal area and provides good aesthetic results.

    背景股前外侧(ALT)皮瓣是最常见的用于头颈部微血管重建的软组织皮瓣。由于射孔器特性的可变性,其收获与一些不可预测性有关,复杂缺陷的损伤或不利配置。前内侧大腿(AMT)皮瓣是一种选择,但低发生率和厚度限制了其实用性。张量筋膜(TFL)穿支(TFLP)皮瓣是补充ALT的绝佳选择。它的穿孔器是一致的,健壮,在附近,并使用ALT穿孔器。方法分析2017年7月至2021年5月29例游离皮瓣以TFLP皮瓣为元素进行头颈重建的临床资料。结果所有病例均计划进行ALT重建。16例没有ALT穿孔器,但有相当大的TFL穿孔器可用。在13个案例中,复杂的缺陷需要同时使用ALT加TFL(5),嵌合(5),和多(3)自由襟翼方式。最常见的穿孔器位置是TFL和臀中肌之间的隔膜。2例皮瓣完全丢失,2例部分坏死。没有延迟辅助治疗。结论TFLP能可靠地补充ALT/AMT轴。嵌合ALT-TFL可以收获大,复杂,多组分,和多维缺陷。
    Background  Anterolateral thigh (ALT) flap is the most common soft tissue flap used for microvascular reconstruction of head and neck. Its harvest is associated with some unpredictability due to variability in perforator characteristics, injury or unfavorable configuration for complex defects. Anteromedial thigh (AMT) flap is an option, but the low incidence and thickness restrict its utility. Tensor fascia lata (TFL) perforator (TFLP) flap is an excellent option to complement ALT. Its perforator is consistent, robust, in vicinity, and lends itself with the ALT perforator. Methods  This study was an analysis of 29 cases with a free flap for head neck reconstruction with an element of TFLP flap from July 2017 to May 2021. Results  All cases were primarily planned for an ALT reconstruction. There was absence of the ALT perforator in 16 cases but a sizable TFL perforator was available. In 13 cases, the complex defect warranted use of both ALT plus TFL in a conjoint (5), chimeric (5), and multiple (3) free flaps manner. Most common perforator location was septocutaneous between the TFL and gluteus medius. There was complete flap loss in two cases and partial necrosis in two. No adjuvant therapy was delayed. Conclusion  TFLP can reliably complement the ALT/AMT axis. Chimeric ALT-TFL can be harvested for large, complex, multicomponent, and multidimensional defects.

    UNASSIGNED: Coverage of soft tissue defects following surgery at the trochanteric area is challenging. Revision surgery in case of compromised wound healing may lead to soft tissue defects requiring reconstruction with pedicled or free flaps. Previous access to the hip joint may jeopardize neurovascular structures relevant to the flap.
    UNASSIGNED: In this study, we evaluated if the use of a pedicled anterior lateral thigh (ALT) flap is a valuable option for soft tissue reconstruction.
    UNASSIGNED: In this retrospective study, seven patients were included. Defect etiology was tumor resection in one case, screw osteosynthesis in another case and total hip arthroplasty in three cases. All patients underwent reconstruction by proximal pedicled anterior lateral thigh (ALT) flap.
    UNASSIGNED: Pedicled ALT flap was a safe procedure in all cases. One patient showed delayed wound healing with need for additional surgery. No further complications were observed.
    UNASSIGNED: Pedicled ALT flap transfer represents a reliable option for soft tissue coverage in the trochanteric area after primary surgery such as hip arthroplasty, osteosynthesis or tumor resection.

    涉及软组织和硬组织的复杂头皮缺损给整形外科医生带来了挑战。每个缺陷的解决方案必须取决于各种因素,甚至基础结构的技术发展。我们提出了一个案例研究,其中患者有明显的全额叶缺损。第一个手术是双顶皮瓣,作为修补缺损的一种选择。然而,没有达到审美满意度。第二次手术使用股前外侧皮瓣以增强美学效果,钛网的放置是一个合适的选择。这种情况可能是不同的解决方案如何导致可变的结果以及在处理复杂的头皮缺陷时需要考虑什么的示例。
    Complex scalp defects involving soft and hard tissues pose challenges for plastic surgeons. The solution for each defect must depend on various factors and even the technical development of the infrastructure. We present a case study in which the patient had a significant total frontal defect. The first surgery was a bi-parietal flap as a salvage option to cover the defect. However, aesthetic satisfaction was not achieved. The second surgery used the anterolateral thigh flap to enhance the aesthetic result, and the placement of titanium mesh was an appropriate choice. This case may be an example of how different solutions can lead to variable results and what needs to be considered when dealing with complex scalp defects.

    本研究旨在调查广泛颅底ORN开放手术后的结果。通过个性化顺序方法进行开放手术,以处理5例广泛的颅底ORN。2例轻症患者行区域清创术和隔离切除术,3例重症患者使用游离股前外侧(ALT)皮瓣进行了广泛切除和重建。使用生物胶和血管化皮瓣封闭颅底骨缺损,以防止术后脑脊液(CSF)泄漏。通过严格遵循抗菌药物管理(AMS)原则的抗生素管理来控制感染。作为结果,在所有患者中,区域性清创术加隔离切除术和广泛切除术均取得了满意的结局.无严重并发症及住院延迟。随访期间(8-19个月),所有的病人都活着,无痛,没有结皮或脓性分泌物,未发生封存或脑脊液渗漏。总之,个性化的顺序方法,包括开放手术,对于广泛的颅底ORN患者,提倡带蒂/血管化游离皮瓣重建和AMS。
    The present study aimed to investigate outcomes following open surgery for extensive skull base ORN. Open surgery through a personalized sequential approach was employed to deal with five cases of extensive skull base ORN. Two patients with mild cases underwent regional debridement and sequestrectomy, and three patients with severe cases underwent extensive resection with reconstruction using free anterolateral thigh (ALT) flap. Biological glues and vascularized flaps were used for obturation of the skull base bony defect to prevent postoperative cerebrospinal fluid (CSF) leakage. The infections were controlled by antibiotic administrations which strictly followed the principles of antimicrobial stewardship (AMS). As results, both regional debridement plus sequestrectomy and extensive resection achieved satisfied outcomes in all patients. No severe complications and delayed hospitalization occurred. During the follow-up period (8-19 months), all patients were alive, pain free, without crusting or purulent discharge, and no sequestration or CSF leakage occurred. In conclusion, a personalized sequential approach including open surgery, pedicled/vascularized free flap reconstruction and AMS was advocated for patients with extensive skull base ORN.

    背景:由于软组织缺损和高并发症风险,由战斗损伤引起的下颌骨缺损的重建对于临床医生而言具有挑战性。这项研究评估了使用非血管化the骨移植物(NVICG)重建战斗损伤患者下颌骨连续缺损的结果。
    方法:通过高速剂获得的连续下颌骨缺损患者,接受或不接受无微血管软组织或局部皮瓣的NVICG重建的患者,包括在研究中。结果变量是由于术后并发症或完全(超过90%)吸收引起的移植物丢失。主要预测变量是受管区的软组织缺损。次要预测变量是缺损的长度。与患者相关的变量,缺陷部位,手术,和其他并发症也进行了评估。采用独立样本t检验进行统计分析。Pearson的卡方检验和Fisher的精确检验,显著性水平为P<0.05。结果:该研究包括24例患者,27例下颌骨缺损。总的来说,重建的总成功率为59.3%。软组织缺损与移植失败及其他并发症显著相关(p<0.05),主要与软组织缺损有关。即使在较小的软组织缺损中,移植成功率也仅为14.3%。反过来,在有足够软组织覆盖的重建中,75.0%的移植物存活。此外,重建延迟较多的患者移植失败明显少于早期手术的患者(p<0.05).在缺损大小和并发症之间没有发现关联。
    结论:足够的软组织覆盖对于重建由战斗损伤引起的下颌骨缺损至关重要。此外,较小的软组织缺损应该用软组织皮瓣覆盖,以避免这些特定损伤的并发症和移植物丢失。如果软组织覆盖足够,甚至可以用NIVICG重建大的缺陷。
    BACKGROUND: Reconstruction of mandibular defects caused by combat injuries is challenging for clinicians due to soft tissue defects and high complication risk. This study evaluated the outcomes of mandibular continuous defects reconstruction with non-vascularized iliac crest graft (NVICG) in patients with combat injuries.
    METHODS: Patients with continuous mandibular defects acquired by high-velocity agents, who received NVICG reconstruction with or without microvascular-free soft tissue or regional flaps, were included in the study. The outcome variable was graft loss due to postoperative complications or full (more than 90 %) resorption. The primary predictor variable was soft tissue defect in the recipient area. The secondary predictor variable was the length of the defect. Variables related to patients, defect site, surgery, and other complications were also evaluated. Statistical analysis was performed with the usage of independent sample t-test, Pearson\'s chi-squared and Fisher\'s exact tests with a significance level of P < 0.05 RESULTS: The study included 24 patients with 27 mandibular defects. Overall, the general success rate of reconstructions was 59.3 %. Soft tissue defects were significantly associated with graft failure and other complications (p < 0.05), which were mostly related to soft tissue defects. The graft success rate was only 14.3 % even in minor soft tissue defects. In turn, in reconstructions with sufficient soft tissue coverage, the graft survived in 75.0 % of the cases. In addition, patients with more delayed reconstruction had significantly fewer graft failures than those with earlier surgery (p < 0.05). No associations were found between defect size and complications.
    CONCLUSIONS: The sufficient soft tissue coverage is essential in the reconstruction of mandibular defects caused by combat injuries. Also, minor soft tissue defects should be covered with soft tissue flaps to avoid complications and graft loss in these specific injuries. Even large defects can be reconstructed with NIVICG if the soft tissue coverage is sufficient.

    BACKGROUND: Persistent complex defects and dysfunctions of the upper aerodigestive tract after tumor surgery represent a major challenge. The aim of this study was to evaluate the effectiveness of an interdisciplinary approach using the free anterolateral thigh flap (ALT) as a reconstruction option in the upper aerodigestive tract.
    METHODS: The retrospective study identified 5 patients with complex defects after laryngectomy/pharyngolaryngectomy (LE/PLE) and multiple revision surgeries between 2017 and 2023. The operations were performed by an interdisciplinary team from otolaryngology, plastic surgery, and visceral/thoracic surgery. The results of the microsurgical reconstruction were analyzed.
    RESULTS: There was an average of six previous operations. The defects included tracheoesophageal fistulas, pharyngocutaneous fistulas, neopharyngeal stenosis, and combinations thereof. Successful reconstruction was achieved in 100% of patients using the ALT flap. In 2 patients, ALT flow-through flaps were used with an additional free jejunal interposition (JI) and in 3 patients split-ALT flaps were used. The major complication rate was 40% and the minor complication rate was 20%.
    CONCLUSIONS: Complex defects of the upper aerodigestive tract with multiple previous operations can be successfully reconstructed. Because of its versatility, the ALT flap seems to be a very good option. Prerequisite for this is an interdisciplinary treatment approach with a critical assessment of patient- and disease-specific factors.
    UNASSIGNED: HINTERGRUND: Persistierende komplexe Defekte und Funktionsstörungen des oberen Aerodigestivtrakts nach tumorchirurgischen Eingriffen stellen eine große Herausforderung dar. Ziel dieser Studie war es, die Wirksamkeit eines interdisziplinären Ansatzes mit der freien lateralen Oberschenkellappenplastik (ALT) als Rekonstruktionsoption im oberen Aerodigestivtrakt zu evaluieren.
    METHODS: Die retrospektive Studie identifizierte zwischen 2017 und 2023 5 Patient*innen mit komplexen Defekten nach Laryngektomie (LE) und multiplen Revisionsoperationen. Die Operationen erfolgten durch ein interdisziplinäres Team aus HNO, Plastischer Chirurgie und Viszeral‑/Thoraxchirurgie. Die Ergebnisse der mikrochirurgischen Rekonstruktion wurden erfasst.
    UNASSIGNED: Es lagen durchschnittlich 6 Voroperationen vor. Die Defekte umfassten tracheoösophageale Fisteln, pharyngokutane Fisteln, Neopharynxstenosen sowie deren Kombination. Eine erfolgreiche Rekonstruktion konnte in 100 % der Fälle durch den ALT-Lappen erreicht werden. In zwei Fällen wurden ALT-Durchflusslappen mit einem zusätzlichen Jejunuminterponat (JI) und in drei Fällen ein Split-ALT-Lappen durchgeführt. Die Major-Komplikationsrate lag bei 40 % und die Minor-Komplikationsrate bei 20 %.
    UNASSIGNED: Komplexe Defekte des oberen Aerodigestivtrakts mit multiplen Voroperationen können erfolgreich rekonstruiert werden. Aufgrund seiner Vielseitigkeit scheint der ALT-Lappen eine sehr gute Option zu sein. Voraussetzung hierfür ist ein interdisziplinärer Behandlungsansatz mit einer kritischen Abwägung der patienten- und krankheitsspezifischen Faktoren.
