Answer:
Dermal overgrafting is when you apply STSG to a bed of dermis or scar tissue after removal of the surface epithelium.
Indications: extensive, unstable, contracted, depressed, pigmented, or hypertrophic scars that are matured. Sometimes you can not excise all the old scar, and thick STSG may increase the ability of the foot to bear weight.
Pinch grafting is when you take small STSG’s and place them in a large wound with granulation tissue to get some epithelialization.
