The purpose of this study is to determine whether intra-dermal versus transcutaneous purse-string closures have similar scar cosmesis and post-operative complications. The investigators will use a split wound model, where half of the wound will be closed with intra-dermal purse-string sutures and the other half will be closed with a transcutaneous purse-string sutures. Three-months post-surgery, the scar will be evaluated via the patient observer scar assessment scale (POSAS), a validated scar instrument, as well as the trace-to-tape method, an objective outcome measure for linear postoperative scars. Any adverse events will also be recorded.
The purse-string closure is a versatile technique that utilizes circumferential tissue advancement for partial or complete closure of circular cutaneous surgical defects. First reported in the 1950s for closure of a malar defect, the purse-string closure is now routinely used for umbilical, urethral, and breast defects as well as for cutaneous surgical defects either alone or in conjunction with top sutures, local flaps, or grafts. Though the purse-string closure was initially described with circumferentially placed intradermal sutures, various modifications to this technique have been publis…
Inclusion Criteria: * 18 years of age or older * Able to give informed consent themselves * Patient scheduled for cutaneous surgical procedure on the head, neck, trunk, or extremities with predicted purse-string closure. * Willing to return for follow up visit Exclusion Criteria: * Incarceration * Under 18 years of age * Pregnant Women
Sutures are placed below the skin surface around a circular surgical wound, and the ends are cinched together like a coin purse.
