Subcutaneous incisionless (subcision) surgery for the correction of depressed scars and wrinkles.

Background: A new method of subcuticular underming for the treatment of depressed cutaneous scars and wrinkles is introduced.

Objective: To define the newly coined term "Subcision" and to describe this minor surgical procedure for treating depressed scars and wrinkles.

Methods: A tri-beveled hypodermic needle is inserted through a puncture in the skin surface (hence, "incisionless" surgery), and its sharp edges are maneuvered under the defect to make subcuticular cuts or "-cisions."

Results: The depression is lifted by the releasing action of the procedure, as well as from connective tissue that forms in the course of normal wound healing.

Conclusion: This technique is useful in treating a variety of cutaneous depressions, including scars and wrinkles.
