The color of its skin paddle closely resembles that of facial skin, making it attractive for facial reconstruction. However, there has been insufficient investigations reporting the use of free IMAP flap. Furthermore, even in such studies, somewhat invasive procedures, including rib cartilage resection, were employed to ensure sufficient pedicle length, potentially increasing donor morbidity. Our report presents two cases of successful facial defect reconstruction using a free IMAP flap harvested with minimal donor site damage, showing its feasibility. In the first case, a 48-year-old male underwent wide excision for a malignant melanoma on his right cheek, resulting in a 4 × 4.5 cm full-thickness defect. A free IMAP flap with a 2.5 cm pedicle, was harvested without rib cartilage resection, preserving IMA main trunk, and transferred with anastomosed to the angular vessels within the defect. The second patient presented with a 4.5 × 3.5 cm basal cell carcinoma on the left cheek, necessitating wide excision and leaving a 6 × 5 cm defect. A free IMAP flap was harvested with the same approach and successfully reconstructed the defect with connected to the superficial temporal vessels using vascular bridge. Both patients were discharged complication-free, with no recurrence during 24 and 15 months of follow-up, respectively. They were highly satisfied with the final skin color and texture outcomes. Harvesting a free IMAP flap while minimizing donor morbidity may offer an attractive option for facial reconstruction.</p>\u0000 </div>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":"44 6","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142120224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.</p>\u0000 </div>","PeriodicalId":18600,"journal":{"name":"Microsurgery","volume":"44 6","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142109379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 28-year-old man suffered a degloving injury on the dorsum of his foot resulting in a 9 × 6cm skin defect, open fracture dislocations, exposure of tendons, and neurovascular injury, which included a 6–7.5 cm segmental defect of the vessels supplying the first, second, and third toes leaving all three toes ischemic.
