Plain flaps are a type of surgical technique used in reconstructive surgery. They involve moving a section of tissue, including skin and underlying structures, from one part of the body to another without a significant blood supply. This method is often used to cover wounds or defects, allowing for healing and restoration of function. These flaps can be classified based on their size and the area from which they are taken. Common examples include skin flaps and muscle flaps. Surgeons carefully assess the recipient site to ensure the best outcome for healing and aesthetic appearance.
