The aim of this letter is to provide details derived from our personal experience with the running intradermal suture. We have developed the cross-running intradermal suture (CRIS) to enhance the strength of closure, decrease the length of incision, and reduce the potential of complications. We employ 5-0 Safil (B/Braun, Tuttlingen, Germany) sutures. The subdermal tissue is closed with interrupted sutures to diminish the tension on the skin. After that, the CRIS is performed to close the skin. To begin, the suture needle enters just beneath the dermis at end A of the incision for the first bite and exits from the mid-dermis (Fig. 1a). Next, a running intradermal closure is performed toward end B. The distance from suture to suture should be 2 to 4 mm. On reaching end B, the needle exits from the mid-dermis and is then passed through the opposing skin edge at the same level but with a direction change (Fig. 1b).
