Skin grafts and flaps are reconstructive techniques used when a wound cannot be closed directly, often due to significant tissue loss from trauma or surgery.1

Skin Grafts

Skin grafts involve transplanting healthy skin from one area of the body to cover a wound. They are generally used for large surface areas or defects where the primary goal is to achieve closure.21
* Split-thickness grafts: Used for large surface areas, these consist of the epidermis and part of the dermis. They heal rapidly but may be aesthetically displeasing.21
* Full-thickness grafts: Used for smaller defects, particularly on the face or hands, these include the entire dermis and provide a better cosmetic match.21

Skin Flaps

Flaps are used when the wound involves the exposure of critical structures such as bone, nerve, or tendon, or when there is a loss of underlying fat tissue. Unlike grafts, flaps maintain their own blood supply, making them more robust.13
* Local flaps: Tissue is rotated from an adjacent area to cover the defect.1
* Free flaps: Tissue is transferred from a distant part of the body when local tissue is insufficient.1
