Summary
This study aims to investigate whether the spacing of the interrupted deep (subdermal) sutures affects surgical wound cosmesis on the trunk and extremities. In other words, the investigator would like to determine which of the following yields a more cosmetically appealing scar: many closely approximated subdermal sutures or fewer, more widely spaced subdermal sutures. The investigator wishes to compare the effects of one versus two centimeter spacing between sutures.
