Therapeutic undermining of scars (Subcision)

Two patients are described with depressed atrophic scars. The first patient had undergone skeletal traction around the knee and the second patient developed an apparent anetoderma of the left side of the nose. Dermal undermining was performed as the only treatment with successful resolution of their contour abnormalities. Only a single treatment session was required in each case. A brief review of this technique is presented.
