"Precise approximation of the wound margin without undue tension and making the wound slightly elevated state, thereby accelerating primary wound healing and minimizing the scar is one of essential techniques of a surgeon. The continuous over-and-over suture provides rapid closure with an even distribution of tension along the length of the wound, but the disadvantage arises if the surgeon wants to remove only a few sutures at a time, and the inversion of wound margin can sometimes occur. The simple interrupted suture takes longer to perform but more selective adjustments of wound edges can be made, and allows for the removal of every other stitch when it is needed. The vertical mattress suture takes long and have relatively poor microcirculation of wound margin but provide a greater wound eversion and precise approximation of the wound margin. The continuous vertical mattress suture is relatively fast, adjusts the tissue layers fairly well and provides good eversion. But the problem arises if the suture breaks. "
