Nylon threads used as drains in free skin grafting.

Monofilament nylon threads are used as drains in free skin grafting; 2-0 or 3-0 nylon threads are usually applied. Nylon drains are available in any operating room, and have no detrimental effects on the grafted skin. The drainage effect of nylon threads is shown in clinical cases and in a simple experimental model. The effect may not be dramatic, but it reduces the volume of hematomas and brings good results in free skin grafting.
