Abstract:
OBJECTIVE:To review the nomenclature, functional unit construction, technical essentials, and prevention and treatment of complications of functional perforator flaps, so as to provide references for the structural and functional reconstruction of composite tissue defects.
METHODS:By retrieving and analyzing domestic and foreign literature on anatomical research, technical innovation and clinical application of functional design and application of perforator flaps, combined with the clinical practice of our team, the methods for harvesting and integrating functional units of perforator flaps were summarized.
RESULTS:Functional perforator flap refers to a perforator flap that, on the basis of perforator blood supply, carries one or more tissue functional units (such as muscles, nerves, lymphatic vessels, lymph nodes, bones, mucous membranes, joints or articular cartilages, etc.) with sufficient blood supply located in the supra-fascia and/or sub-fascia, and is used to reconstruct one or more functions of the recipient site. The design and transfer of functional perforator flaps should not only meet the needs of precise coverage of the wound, but also reconstruct the functions of the recipient site such as muscle contraction, flap sensation, lymphatic drainage, blood flow bridging, bone growth, glandular secretion or joint movement, while avoiding iatrogenic dysfunction in the donor site.
CONCLUSION:Functional perforator flaps have broken through the limitation of "wound coverage" and realize the integrated reconstruction of "structure-function-aesthetics".
