    The pedicled anterolateral thigh (PALT) flap is an underutilized flap for locoregional reconstruction largely because methods to maximize its reach are neither universally implemented nor fully understood. In addition, most of the available literature has focused on the utility of the free anterolateral thigh flap with less emphasis on the PALT flap. Moreover, flap design concepts to maximize its utility and reach and optimize outcomes have not been comprehensively described. In an effort to address this knowledge gap, the authors sought to review their institution’s experience with the PALT flap for locoregional reconstruction.Pure autologous breast reconstruction in thin patients creates challenges. This review highlights techniques to optimize the scarce donor tissue available, approaches to reconstruction, and microsurgical techniques. A systematic approach to maximize breast volume and the skin envelope in patients who underwent pure autologous breast reconstruction by a single senior surgeon is presented with a clinical case series. Included in the study were 125 patients (217) with autologous breast reconstructions. Although DIEP flaps were the commonest flap used overall (79%), within in the low body mass index (50%).Autologous breast reconstructions have grown in popularity because of their durability, aesthetic outcomes, symmetry, increase in external beam radiotherapy use, and potential aesthetic enhancement at the donor site. Increasing patient expectations for predictable high aesthetic outcomes with minimal complications or need for further procedures has been met by refinement in the use of flaps. The authors’ microsurgical breast reconstruction center aims to provide this while delivering efficient service. The deep inferior epigastric flaps form 85% and transverse upper gracilis and profunda artery perforator flaps account for 10%; lumbar artery perforator flaps are a new addition to the authors’ armamentarium.Head and neck reconstructive microsurgery is constantly innovating because of a combination of multidisciplinary advances. This article examines recent innovations that have affected the field as well as presenting research leading to future advancement. Innovations include the use of virtual surgical planning and three-dimensional printing in craniofacial reconstruction, advances in intraoperative navigation and imaging, as well as postoperative monitoring, development of minimally invasive reconstructive microsurgery techniques, integration of regenerative medicine and stem cell biology with reconstruction, and the dramatic advancement of face transplant.As microsurgical expertise has improved, allowing for the safe transfer of smaller and more refined flaps, free tissue transfer has continued to gain popularity for the management of pediatric soft tissue and bony defects. For the past 2 decades pediatric microsurgery has been shown to be technically feasible and reliable. The major advantage of free tissue transfer in children is the ability to reconstruct defects in a single stage, avoiding the historic treatments of skin grafting, tissue expansion, and pedicled flaps. This article reviews the present state-of-the-art in pediatric microsurgery.Reconstruction of soft tissue defects following tumor ablation procedures in the trunk and extremities can challenge the microsurgeon. The goal is not just to provide adequate soft tissue coverage but also to restore form and function and minimize donor site morbidity. Although the principles of the reconstructive ladder still apply in the trunk and extremities, free tissue transfer is used in many cases to optimally restore form and function. Microsurgery has changed the practice in soft tissue tumors, and amputation is less frequently necessary.Novel and combined tissue transfers from the lower extremity provide new tools to combat soft tissue defects of the hand, foot, and ankle, or fracture nonunion. Flaps can be designed for special purposes, such as providing a gliding bed for a grafted or repaired tendon or for thumb or finger reconstruction. click here Propeller flaps can cover soft tissue defects of the leg and foot. In repairing severe bone and soft tissue defects of the lower extremity, combined approaches, including external fixators, one-stage vascularized bone grafting, and skin or muscle flap coverage of the traumatized leg and foot, have become popular.Microsurgical tissue transfer may provide reconstructive option for extensive loss of tissues due to upper extremity trauma or tumor resection. This article reviews the authors’ experience in using microsurgical tissue transfers for reconstruction of upper extremity trauma.Vascularized small-bone grafting is an efficient and often necessary surgical approach for nonunion or necrosis of several bones in particular sites of the body, including scaphoid, lunate, distal ulna, and clavicle. The medial femoral condyle is an excellent graft source that can be used in treating scaphoid, ulna, clavicle, or lower-extremity bone defects, including nonunion. Vascularized bone grafting to the small bones, particularly involving reconstruction of damaged cartilage surfaces, should enhance subchondral vascular supply and help prevent cartilage regeneration. Vascularized osteoperiosteal and corticoperiosteal flaps are useful for treating nonunion of long bones.Vascularized osteochondral flaps are a new technique described for the reconstruction of challenging articular defects of the carpus. The medial femoral trochlea osteochondral flap is supplied by the descending geniculate artery. This osteochondral flap has shown promise in the treatment of recalcitrant scaphoid proximal pole nonunions and advanced avascular necrosis of the lunate. The anatomy, surgical technique, and results are discussed, with clinical cases provided.The main goals of treating severe crush injuries are debriding away devitalized tissue and filling any resultant dead space with vascularized tissue. In the authors’ experience, the most ideal methods for soft tissue coverage in treating crush injuries are the iliac flap, the adipofascial lateral arm flap, and the gracilis flap. Accompanying bone defects respond very well to free corticoperiosteal flaps. Digital defects often require the use of complete or subtotal toe transfer to avoid amputation and restore function to the hand.
