Application of Bilateral De-epithelialized Hinge Flap to Correct the Deep Depressed Scar

Abstract

The scar is formed following the trauma or severe inflammation, and it is one of the critical problems in the field of plastic and reconstructive surgery. To date, continuous efforts have been made to correct scar. Still, however, it remains challenging to remove scar completely. The scar formation is a process that occurs during the wound healing, which is characterized by the synthesis of abnormal collagen and irregular changes on the skin surface [1]. Various factors that may affect the wound healing process, leads to the formation of various types of scars such as linear scar and depressed one. Most cases of the linear scars are corrected using a scar revision. This leads to good treatment outcomes. In addition, small-sized depressed scars are corrected using a dermal-fat grafting or an autologous fat grafting [2]. But the fillers are disadvantageous in that the rate of absorption is relatively higher and additional surgeries are required to provide filling materials. Various methods have therefore been used to correct deep depressed scars. But the correction of deep depressed scars poses challenging problems for plastic surgeons.
