free flap(redirected from Free Flap/Free Tissue Transfer)
1. a mass of tissue for grafting, usually including skin, only partially removed from one part of the body so that it retains its own blood supply during transfer to another site.
2. an uncontrolled movement.
advancement flap sliding flap.
axial pattern flap a myocutaneous flap containing an artery in its long axis.
free flap an island flap detached from the body and reattached at the distant recipient site by microvascular anastomosis.
island flap a flap consisting of skin and subcutaneous tissue, with a pedicle made up of only the nutrient vessels.
jump flap one cut from the abdomen and attached to a flap of the same size on the forearm. The forearm flap is transferred later to some other part of the body to fill a defect there.
myocutaneous flap a compound flap of skin and muscle with adequate vascularity to permit sufficient tissue to be transferred to the recipient site. See also axial pattern flap and random pattern flap.
pedicle flap a flap consisting of the full thickness of the skin and the subcutaneous tissue, attached by tissue through which it receives its blood supply. Called also pedicle graft.
random pattern flap a myocutaneous flap with a random pattern of arteries, as opposed to an axial pattern flap.
rope flap tube flap.
rotation flap a local pedicle flap whose width is increased by having the edge distal to the defect form a curved line; the flap is then rotated and a counterincision is made at the base of the curved line, which increases the mobility of the flap.
skin flap a full-thickness mass or flap of tissue containing epidermis, dermis, and subcutaneous tissue.
sliding flap a flap carried to its new position by a sliding technique; called also advancement flap.
tube flap (tubed pedicle flap) a bipedicle flap made by elevating a long strip of tissue from its bed except at the two extremities, the cut edges then being sutured together to form a tube.
flap in which the donor vessels are divided, the tissue is transported to another area, and the flap is revascularized by anastomosis of vessels in the recipient bed to the artery and vein(s) of the flap.
free flapReconstructive surgery An autologous tissue flap with anastomosed blood vessels
free flap(frē flap)
Island flap in which the donor vessels are severed proximally, the flap is transported as a free object to the recipient area, and the flap is revascularized by anastomosing its supplying vessels to vessels there.
A section of tissue detached from its blood supply, moved to another part of the body, and reattached by microsurgery to a new blood supply.

1. a mass of tissue for grafting (1), usually including skin, only partially removed from one part of the body so that it retains its own blood supply during transfer to another site. See also specific sites, such as conjunctival.
2. an uncontrolled movement.
release of a portion of tissue and reattachment at an advanced position.
in circumcostal gastropexy or belt loop gastropexy a seromuscular flap from the pyloric antrum is passed under a rib or strip of abdominal wall muscle and sutured back to its position on the stomach.
axial pattern flap
pedicle flaps with a direct cutaneous artery and vein are transferred to defects within their radius with a high chance of survival.
the space created by undermining skin between two parallel incisions can be used to reconstruct skin defects, usually onto a distal limb which is inserted into the space. Called also pouch flap.
a surgical procedure in which a flap is created in a flat bone by leaving one side of a rectangle cut in the bone intact. Used for gaining access to a cavity, e.g. a sinus, with minimum disfigurement.
a section of mucosa released from mucosa of the gum and lip used to close oronasal fistulas.
a detached piece of cartilage as a result of osteochondrosis dissecans, seen particularly in the shoulder of dogs.
skin with muscle, bone or cartilage.
cranial sartorius muscle flap
the muscle is dissected free, severed at its insertion on the tibia and used to repair prepubic tendon ruptures or femoral hernias.
a skin flap from an eyelid is used to fill a defect in the opposite lid. Called also Cutler-Beard or bucket-handle flap.
external abdominal oblique muscle flap
can be used to repair defects in the abdominal wall or caudal thoracic wall.
an island flap detached from the body and reattached at the distant recipient site by microvascular anastomosis.
interlocking processes in adult cortical lens fibers.
to increase exposure for surgery in the colorectal region, osteotomies of the pubic and ischial bones may be required. The bone flap created is reflected and replaced at the conclusion of the surgical procedure.
a flap consisting of skin and subcutaneous tissue, with a pedicle made up of only the nutrient vessels.
a section of oral mucosa, gingiva and underlying periosteum in periodontal surgery and tooth extractions.
used in repair of defects in the oral cavity such as oronasal fistula and those created by excision of tumor and bone.
a compound flap of skin and muscle with adequate vascularity to permit sufficient tissue to be transferred to the recipient site.
see pedicle graft.
transposed through subcutaneous tunnels and used to cover soft tissue defects, stimulate granulation and control adhesion.
a technique for repair of cleft soft palate with two flaps, one on the oral side and one on the nasal side, and with the assistance of relaxing incisions these are overlapped to ensure an adequate seal.
one made by elevating a long strip of tissue from its bed except at its two ends, the cut edges then being sutured together to form a tube. Called also tubed graft.
rotary door flap
a myocutaneous flap in which an island of skin is rotated to fill the airway defect created by laryngeal resection.
see pedicle graft.
a standard technique in skin grafting; based on the part isolation of a graft by creation of a flap which retains its original circulation while becoming established at the new site on the new blood supply. Many types of flap are used, e.g. axial pattern, bipedicle, composite, delayed tube, direct, interpolating, reverse saphenous conduit. See also skin graft.
technique for closing skin wounds where there is a large deficiency of skin. Includes sliding-H flap and Z-flap or Z-plasty. Skin around the defect is separated from its subcutis and the defect repaired by strategic additional incisions and the use of tension sutures.
a method of placing a tracheostomy tube which will minimize the subsequent formation of excessive granulation tissue. The opening is made by cutting a flap across two tracheal rings and reflecting it to permit entry of the tube. After extubation, the flap is replaced.
rectangular flap of skin repositioned to fill a defect.
tube flap, tunnel flap
