Aesthetic Outcome of Running Cuticular Suture Distance (2mm vs 5mm) From Wound Edge on the Closure of Linear Wounds on the Head and Neck: a Randomized Evaluator Blinded Split Wound Comparative Effective Trial.

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. This study aims to investigate whether the spacing of the interrupted cutaneous sutures affects surgical wound cosmesis on the face and neck. In other words, the investigators would like to determine which of the following yields a more cosmetically appealing scar: many closely approximated sutures or fewer, more widely spaced sutures. The investigators wish to compare the effects of two versus five millimeter spacing between sutures. It is possible that fewer, more widely spaced sutures may leave more open space in the wound, leaving more tension to pull on those few sutures, possibly encouraging the wound to dehisce and make it harder to approximate the wound edges yielding a less cosmetically appealing scar compared to placing many closely approximated sutures which would decrease the tension and likely better approximate the wound edges yielding a more cosmetically appealing scar. On the other hand, the investigators may find that suture spacing has no effect on wound cosmesis and that placing fewer, more widely spaced sutures is much more time efficient. The investigators may also find that the effect of suture spacing on wound cosmesis is dependent on wound tension. For example, perhaps the suture pacing would have no effect on the cosmesis of a wound under no tension, however, for a wound under high tension, it is possible that many closely approximated sutures would yield better cosmetic results for the reasons listed above.
