Subcision for Scars
This simple local anesthesia procedure is designed to improve depressed scars resulting from acne scarring or any scar resulting from trauma or surgery that is depressed below the skin level. Many of these scars are depressed because of loss of skin thickness or tethering of the scar to deeper tissue. The creation of a new scar beneath the depressed scar combined with transection of the tether to underlying tissue results in an elevation of the scar. This procedure can be performed on single depressed lesions or on a hundred acne scars of the face in one sitting.
The Subcision Procedure
During a subcision procedure, the patient is asked to mark each of the scars that he/she dislikes. These areas are marked and then numbed with local anesthesia. A special blade is used to create a pocket beneath each scar that releases any tethering and creates new scar tissue below the depressed scar. The resultant action during the healing process is to elevate the depressed scar. It is not uncommon to see a 30% or more improvement of each scar with a single subcision treatment. Multiple treatments are typically required to achieve the dramatic outcome that patients thought they could never achieve.
The combination of subcision with Fraxel Dual® laser has proved to be the most effective acne scar treatment to date. In some cases of severe scarring, dermal grafting can be combined with subcision to create an immediate correction.
