Split-Thickness Skin Graft
A skin graft containing epidermis and partial dermis, typically used for large wound coverage.
Full Definition
A split-thickness skin graft (STSG) is a reconstructive technique that involves harvesting a thin layer of skin containing the epidermis and a portion of the dermis, typically using a dermatome. The graft thickness usually ranges from 0.008 to 0.012 inches. STSGs are commonly used to cover large surgical defects, burns, or chronic wounds because they have better survival rates than full-thickness grafts due to their ability to be nourished by plasmatic imbibition. However, they may have inferior cosmetic outcomes with potential for contraction and pigment changes over time.
Usage
Usage note: Abbreviate as STSG after first use; specify donor site and thickness when documenting.
