Smash grafting
Smash grafting
Using this approach, a thin to ultra-thin graft is smashed into small pieces using sterile scissors for about 15 to 20 minutes until a smooth paste is created. The paste is then placed in NS to maintain graft moisture. Once the RS is prepared, the excess NS is drained and a sterilized spatula is used to apply the paste. The paste remains exposed to room air for 15 to 30 minutes to optimize graft adherence and allow for mild drying. Patients are placed on prophylactic antibiotics until dressings are removed 1 week later.29
Smash grafting has the distinct advantage of requiring equal amounts of DS and RS tissue compared to the greater DS graft size required in STSG to account for RS contracture. This method also eliminates the need for marking the dermal side to ensure proper graft placement at the RS, as is required for STSG and SBEG. It generally takes at least 2 weeks postoperatively to see pigment spread, at which time phototherapy can be initiated. Repigmentation is typically expected by 6 months postoperatively. Studies have shown excellent color and texture match, and this technique is simple, requires minimal specialized equipment, and is cost-effective.29
