How is a split-thickness skin graft (STSG) done?

Plastic Surgery

A split-thickness skin graft includes the epidermis and part of the dermis only. The thickness will depend on the location of the wound and the donor site. The graft thickness (0.005-0.012 inches) thin or (0.018-0.03 in.) thick graft. Commercial dermatomes are used to take the skin graft from the donor site. The grafts can then be meshed which expands it up to 9 times its original size and creates multiple tiny incisions that allow for plasmatic imbibition and inosculation. The donor site can be reused in 6 weeks and will heal by re-epithelialization.
