A New Modified S-plasty for Skin Defect Closure.

Background: Dog-ear, or standing cone deformity, is a common problem during surgical procedures. Multiple methods have been reported to correct the deformity but most create long scars or excessive normal skin loss.

Methods: We designed a simple and convenient procedure to remove small- and medium-sized skin defects. Based on mathematical calculations, the procedure is an easily designed surgical technique.

Results: All of our patients healed uneventfully with no significant complications. The procedure not only resulted in a shortened surgical incision and preserved a greater amount of healthy skin, but also left a simple "S-shaped" curvilinear scar with favorable esthetic outcomes.

Conclusion: This novel modified S-plasty is a simple tool to successfully remove skin defects, with a low deformity risk.
