Subcision With Platelet-Rich Plasma and Microneedling Versus Subcision With Saline and Micro-needling in Treatment of Posttraumatic Scars: Randomized Clinical Trial

The scars at the level of the skin represent a normal and inevitable process of healing traumatic or surgical lesions, but except for the appearance of the skin, they also have a profound psychological impact . Thus, people with scars try to integrate them into their sense of self to gain psychological acceptance .

Many treatment options have been developed for the management of traumatic scars .Surgical intervention is an invasive technique, surgery has a high risk of inducing new scar formation .

Non-surgical approaches for the treatment of traumatic scars include topical treatments and minimally invasive approached as subcision,microneedling and laser.

Autologous platelet-rich plasma is plasma with a higher concentration of platelets than normally found, it can enhance wound healing which has been demonstrated in controlled studies for soft and hard tissues . The application of autologous platelet-rich plasma to surgical wounds has been shown to accelerate tissue repair and reduce postoperative pain .

Subcision is a procedure in which a needle is inserted under the skin and passed in multiple directions . Although subcision is adequate as a stand-alone treatment, improved results are achieved when it is combined with other modalities.
