The investigators aim to determine how suture spacing affects cosmetic outcome of wound healing. One side (1/2 of the wound length) was sutured with 10 mm suture spacing

The wound was divided in half and sutures were spaced 5mm or 10mm apart depending on side. The sutures were removed at 2-week follow-up appointment and photographs were taken. The Patient and Observer Scar Assessment Scale (POSAS) was then performed by both patient and physician.

The wound was divided in half by placing a single 4-0 Polysorb suture in the midpoint of the wound based on ruler measurement. Simple interrupted nylon sutures were spaced approximately 5mm or 10mm apart depending on side. The sutures were then removed at 2-week follow-up appointment. The Patient and Observer Scar Assessment Scale (POSAS) was then performed by both patient and physician. The observer scale consists of six items (vascularity, pigmentation, thickness, relief, pliability and surface area), and all items were scored on a scale from 1 ('like normal skin') to 10 ('worst scar imaginable'). The patient scale also includes six items (color, itch, pain, thickness, stiffness, and irregularity) and all items were scored on a similar scale from 1 ('like normal skin') to 10 ('worst scar imaginable').

Wounds were also assessed for complications. Difficulty removing sutures was assessed by presence of either one of the following: unable to directly visualize suture knot or need to probe into wound to remove suture. Wound dehiscence was defined as at least a 1mm separation of the wound edge for at least 50% of the length of the wound closure. Edge necrosis was defined as eschar and necrosis of the wound edge for at least 50% of the wound closure. Infection was defined as any wound that had redness, pain and exudate.
