The interrupted vertical and horizontal mattress suture techniques are two of the most commonly used skin closure methods. These mattress sutures promote wound edge eversion and less prominent scarring. Vertical and horizontal mattress sutures allow for skin edges to be closed under tension when wound edges have to be brought together over a distance. The corner stitch, a variation of the horizontal mattress suture, is commonly used for closure of angled skin flaps or wounds. Although mattress sutures can produce surface scarring or "railroad marks," early removal of these sutures can limit this damage.
