Flap

A block of tissue moved with its own blood supply to reconstruct a defect. It may remain attached by a pedicle or be detached and reattached by microvascular anastomosis.

Related: Pedicled Flap, Free Flap, Perforator Flap
Pedicled Flap

A flap that stays attached to the donor site by a vascular leash, which supplies its blood. It is rotated or advanced into the defect without dividing the vessels.

Related: Flap, Free Flap, Pivot Point
Free Flap

A flap completely detached from the body and transferred to a distant site, where its artery and vein are reconnected to recipient vessels under a microscope.

Related: Flap, Microvascular Anastomosis, Perforator Flap
Perforator Flap

A flap raised on small vessels that pierce the deep fascia and supply the overlying skin and fat. It spares the underlying muscle and its function.

Related: Flap, Free Flap, Angiosome
Angiosome

A three-dimensional block of skin, soft tissue, and bone supplied by one named source artery. It helps surgeons plan flaps and predict which tissues survive together.

Related: Perforator Flap, Flap
Pivot Point

The fixed point at the base of a pedicled flap around which the flap rotates. Its distance from the defect limits how far the flap can reach.

Related: Pedicled Flap, Arc of Rotation
Arc of Rotation

The circular path a pedicled flap can sweep around its pivot point. It defines the territory the flap can cover without tension or vascular compromise.

Related: Pivot Point, Pedicled Flap
Delay Phenomenon

A staged procedure in which a flap's blood supply is partially interrupted before transfer. This conditioning improves survival of the flap's distal portions.

Related: Flap, Pedicled Flap
Random Pattern Flap

A skin flap whose blood supply comes from unnamed dermal and subdermal vessels rather than a specific artery. Its length-to-width ratio is limited by perfusion.

Related: Axial Pattern Flap, Flap
Axial Pattern Flap

A flap designed along a known direct cutaneous artery running in its long axis. It can be longer and more reliable than a random pattern flap.

Related: Random Pattern Flap, Pedicled Flap
Microvascular Anastomosis

The surgical joining of very small arteries or veins, usually under magnification, to restore blood flow. Patency depends on precise technique and vessel alignment.

Related: Free Flap, Thrombosis
Thrombosis

Clot formation inside a vessel or flap pedicle that blocks blood flow. In free flaps it is a leading cause of failure and often requires urgent re-exploration.

Related: Microvascular Anastomosis, Free Flap, Flap Monitoring
Flap Monitoring

Serial clinical and adjunctive assessment of a flap's color, temperature, capillary refill, and Doppler signals. Early detection of compromise allows salvage before tissue dies.

Related: Thrombosis, Free Flap
Skin Graft

A sheet of epidermis and dermis, or epidermis alone, transplanted without its own blood supply. It survives by plasmatic imbibition and then revascularizes from the recipient bed.

Related: Split-Thickness Graft, Full-Thickness Graft, Graft Take
Split-Thickness Skin Graft

A graft containing epidermis and part of the dermis, harvested at a set thickness. It survives more readily but contracts more and leaves a donor site that re-epithelializes.

Related: Skin Graft, Full-Thickness Skin Graft, Meshing
Full-Thickness Skin Graft

A graft containing the entire epidermis and dermis. It contracts less and gives better color and texture match, but requires a well-vascularized bed and a closed donor site.

Related: Skin Graft, Split-Thickness Skin Graft
Graft Take

The process by which a skin graft becomes adherent and revascularized by the recipient bed. It depends on a clean, well-perfused bed and immobility.

Related: Skin Graft, Hematoma
Meshing

Cutting slits in a skin graft to expand its surface area and allow drainage of fluid. It improves contouring on irregular beds but creates a patterned appearance.

Related: Split-Thickness Skin Graft, Skin Graft
Hematoma

A collection of blood beneath a flap, graft, or wound closure. It can lift tissue off its bed, impair perfusion, and cause infection or graft loss.

Related: Seroma, Graft Take
Seroma

A collection of serous fluid in a dead space under a flap or wound. It can cause swelling, delay healing, and predispose to infection if not drained.

Related: Hematoma, Closed Suction Drain
Closed Suction Drain

A tube placed in a surgical dead space and connected to suction to remove accumulating blood and serum. It reduces seroma and hematoma formation after flap surgery.

Related: Seroma, Hematoma
Tissue Expansion

Gradual stretching of skin by an implanted silicone balloon filled over weeks. The expanded skin is then used to reconstruct a nearby defect with matched color and texture.

Related: Flap, Scar Revision
Z-Plasty

A scar revision using two triangular flaps transposed to lengthen a contracture and reorient the scar. It redistributes tension and helps break up a linear scar.

Related: Scar Revision, Contracture
Scar Revision

Surgical or adjunctive treatment to improve the appearance, position, or function of a scar. Techniques include excision, Z-plasty, and resurfacing.

Related: Z-Plasty, Contracture, Hypertrophic Scar
Hypertrophic Scar

A raised, thickened scar that stays within the boundaries of the original wound. It often improves over time and responds to pressure, silicone, or steroid injection.

Related: Keloid, Scar Revision
Keloid

An overgrowth of scar tissue that extends beyond the original wound margins and tends to recur. It is more common in darker skin and after ear piercing or burns.

Related: Hypertrophic Scar, Scar Revision
Contracture

Shortening and tightening of scar tissue or muscle that restricts movement or distorts nearby structures. It commonly follows burns across joints.

Related: Z-Plasty, Scar Revision
Mammoplasty

Any operation that reshapes or alters the size of the breast, including reduction, augmentation, and mastopexy. The term covers both aesthetic and reconstructive goals.

Related: Mastopexy, Breast Reduction, Breast Augmentation
Mastopexy

Surgery to lift and reshape a ptotic breast without substantially changing its volume. It repositions the nipple-areolar complex and tightens the skin envelope.

Related: Mammoplasty, Breast Ptosis
Breast Ptosis

Drooping of the breast caused by stretching of skin and suspensory ligaments. It is graded by the position of the nipple relative to the inframammary fold.
