Aesthetic Outcome of Running Cuticular Suture Distance (2mm vs 5mm)

Sutures are the standard of care in repairing cutaneous wounds. The majority of surgical reconstructions following a Mohs micrographic surgery and standard surgical excisions require two layers of sutures: a deep (subcutaneous) layer and a top (cutaneous) layer. The deep layer dissolves naturally whereas the top layer may necessitate removal if non-absorbable sutures are used. Given the overall lack of evidence in the literature, the choice of suturing technique is largely dependent on the surgeon's preference.

This study aims to investigate whether the distance of simple cuticular suture placement from the wound edge affects wound cosmesis on the head and neck. In other words, we would like to determine which of the following yields a more cosmetically appealing scar: cuticular sutures placed 2 mm from wound edge or cuticular sutures placed 5mm from wound edge.

Although a Dermatologic surgery textbook states that simple cuticular sutures should be placed 3 mm-5 mm from the wound edge1, there have not been any studies to evaluate the optimal distance from wound edge to achieve the most cosmetically appealing scar.

Overall, there is paucity of data regarding the optimal distance of cuticular suture placement from the wound edge to achieve the most cosmetically appealing scar. The research team hope that the study will provide new insight in cutaneous surgery.
