Article Abstract
Introduction: Coronavirus disease 2019 (COVID-19) affects the vascular system, subjecting patients to a hypercoagulable state. This is of particular concern for the success of microvascular free flap reconstruction. This study aims to report head and neck free flap complications in patients with COVID-19 during the perioperative period. We believe these patients are more likely to experience flap complications given the hypercoagulable state.
Methods: This is a multi-institutional retrospective case series of patients infected with COVID-19 during the perioperative period for head and neck free flap reconstruction from March 2020 to January 2022.
Results: Data was collected on 40 patients from 14 institutions. Twenty-one patients (52.5%) had a positive COVID-19 test within 10 days before surgery and 7 days after surgery. The remaining patients had a positive test earlier than 10 days before surgery. A positive test caused a delay in surgery for 16 patients (40.0%) with an average delay of 44.7 days (9-198 days). Two free flap complications (5.0%) occurred with no free flap deaths. Four patients (10.0%) had surgical complications and 10 patients had medical complications (25.0%). Five patients (12.5%) suffered from postoperative COVID-19 pneumonia. Three deaths were COVID-19-related and one from cancer recurrence during the study period.
Conclusion: Despite the heightened risk of coagulopathy in COVID-19 patients, head and neck free flap reconstructions in patients with COVID-19 are not at higher risk for free flap complications. However, these patients are at increased risk of medical complications.

Background: Free flap transfer is an essential technique for head and neck reconstruction after oncological ablative resection. Selection of recipient vessels can be challenging in patients with a history of neck dissection and/or radiotherapy. We analyzed outcomes with regard to recipient vessel selection and flap failure, referring to patients' histories of radiotherapy and/or neck dissection.

Introduction: Complex soft tissue injuries in the facial area can arise from various causes. Surgeons face significant challenges when reconstructing these injuries, as they must select appropriate materials based on texture and color, while also considering their composition and properties. The anterolateral thigh (ALT) flap has emerged as a versatile option in clinical reconstructive surgery, offering many advantages over other free flaps.

In such cases, current options for dental rehabilitation include printed patient-specific subperiosteal implants or zygomatic implants.
Methods: The authors report three cases of maxillary tumour resections that led to medium-to-large defects reconstructed using composite scapulo-dorsal free flaps.

Periorbital defects resulting from oncologic resections, trauma, or congenital malformations pose a complex reconstructive challenge, due to the need to simultaneously restore eyelid function and facial esthetics. We present the case of a male patient in his seventh decade of life with a right orbitomalar squamous cell carcinoma, who underwent a wide oncologic resection involving the upper and lower eyelids, as well as the malar and infraorbital regions. Reconstruction was performed using a radial free forearm flap from the left arm, including the palmaris longus tendon, which was strategically anchored to the medial canthus and orbital rim to provide dynamic eyelid support.

Vascularized reconstruction of bone defects in the foot after osteomyelitis is a complex procedure that requires an orthoplastic collaboration. This case demonstrates the successful use of a free osteocutaneous fibula flap with a perforator-based skin island to reconstruct the medial midfoot following a late-onset infection after fusion for osteonecrosis. A 63-year-old woman presented after osteonecrosis and failed surgeries, including talonavicular and naviculocuneiform arthrodesis complicated by infection.
