These techniques are utilized for depressed scars such as ice pick and boxcar scars. According to the diameter of the scar, a biopsy punch of appropriate size is used to excise the scar.
Punch excision and closure: If the scar is > 3.5 mm in size, it is excised and sutured after undermining, in a direction parallel to the relaxed skin tension lines.
Punch excision and closure: If the scar is > 3.5 mm in size, it is excised and sutured after undermining, in a direction parallel to the relaxed skin tension lines.
Punch incision and elevation: If the depressed scar has a normal surface texture, it is incised up to the subcutaneous tissue and elevated to the level of the surrounding skin.
Punch excision and grafting: Depressed pitted ice pick scars up to 4 mm in diameter, are excised and replaced with an autologous, full-thickness punch graft. The donor site is commonly the postauricular region or the buttock. Care should be taken to avoid cobblestoning, which is a common complication.
These punch excision techniques are followed by resurfacing to achieve optimum results
