extended out parallel from the wound, creating a rectangle with one edge remaining intact. This rectangle is freed from the deeper tissues and then stretched (or advanced) forward to cover the wound. The flap is disconnected from the body except for the uncut edge which contains the blood supply which feeds in horizontally. A rotation flap is similar except instead of being stretched in a straight line, the flap is stretched in an arc. The more complex transposition flap involves rotating an adjacent piece of tissue, resulting in the creation of a new defect that must then be closed.
288: 264: 428:. This allows for a larger area to be freed from surrounding and underlying tissue, leaving only a small pedicle containing the vessels. Reverse-flow flaps are a type of axial flap in which the supply artery is cut on one end and blood is supplied by backwards flow from the other direction. Random flaps are simpler and have no named blood supply; they are supplied by the subdermal plexus. 276: 541: 494:. The most notable risk in this procedure is flap death, where the flap loses blood supply. The loss of blood can be due to many reasons, but is commonly due to tension on the vascular supply and insufficient blood flow to the end segments of the flap. This can sometimes be fixed with another surgery or using additional methods of healing in the reconstructive ladder. 151: 201:. Blood is mainly supplied to the skin by two networks of blood vessels. The deep network lies between the dermis and the subcutaneous tissue, while the shallow network lies within the papillary layer of the dermis. The epidermis is supplied by diffusion from this shallow network and both networks are supplied by 325:
Distant flaps are used when the donor site is far from the defect. These are the most complex class of flap. Direct or tubed flaps involve having the flap connected to both the donor and recipient sites simultaneously, forming a bridge. This allows blood to be supplied by the donor site while a new
307:
Regional or interpolation flaps are not immediately adjacent to the defect. Instead, the freed tissue "island" is moved over or underneath normal tissue to reach the defect to be filled, with the blood supply still connected to the donor site via a pedicle. The pedicle can be removed after a new

This robust and redundant blood supply is important in flap surgery, because flaps are cut off from other blood vessels when it is raised and removed from its surrounding native tissue. The remaining blood supply must then keep the tissue alive until additional blood supply can be formed through
301:
Local flaps are created by freeing a layer of tissue and then stretching the freed layer to fill a defect. This is the least complex type of flap and includes advancement flaps, rotation flaps, and transposition flaps, in order from least to most complex. With an advancement flap, incisions are
103:, which do not have an intact blood supply and relies on the growth of new blood vessels. Flaps are done to fill a defect such as a wound resulting from injury or surgery when the remaining tissue is unable to support a graft, or to rebuild more complex anatomic structures like breasts or jaws. 564:
where the tilemakers' caste would reconstruct noses using regional flaps due to the practice of nose amputations as a form of legal punishment. The next description of flap surgery comes from Celsus, an ancient Roman who described the advancement of skin flaps from 25 BC to 50 AD. In the 15th

is a concept first coined by Ian Taylor in 1987. It is a three-dimensional region of tissue that is supplied by a single artery and can include skin, soft tissue, and bone. Adjacent angiosomes are connected by narrower choke vessels, and multiple angiosomes can be supplied by a single artery.

Fasciocutaneous flaps contain subcutaneous tissue and deep fascia, resulting in a more robust blood supply and ability to fill a larger defect. The Cormack and Lamberty classification is used for the vascular supply of faciocutaneous flaps. Examples: temporoparietal and anterolateral thigh

within the first 2 days following surgery. After the immediate postoperative risk, the flap will continue to heal adhering to the stages of normal wound healing and will take over 3 months for an incision to be at 80% tensile strength compared to normal tissue.
