Study Details

Brief summary:

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.

Interventions and Outcome Measures

Arms

experimental: Intra-dermal purse-string closure on Side A

For all participants, one wound side half will be labeled as A and the other side as B. Side A will be closed with a intra-dermal purse-string closure, and Side B will be closed with a transcutaneous purse-string closure.

Interventions

Intra-dermal purse-string closure

Sutures are placed below the skin surface around a circular surgical wound, and the ends are cinched together like a coin purse.

Transcutaneous purse-string closure

Sutures are placed through the skin surface around a circular surgical wound, and cinched together like a coin purse.

Primary outcome measure

  • Observer Scar Assessment as measured by Patient Observer Scar Assessment Score (POSAS) [ Time Frame: 3 months ]
