Subcision is a minor surgical procedure used for treating depressed cutaneous scars and wrinkles. It is also called subcutaneous incisional surgery. Subcision is performed using a special hypodermic needle inserted through a puncture in the skin surface. The sharp edge of the needle is used to break fibrotic strands that are tethering the scar to the underlying tissue.

The release of the fibrotic strands and new collagen deposition caused by wound healing leads to cosmetic improvement of the scar. Subcision can be safely performed in the outpatient setting and is usually well tolerated.

What are the indications for subcision?

The decision to perform subcision will depend on the type, location, and severity of scarring; patient preference and expectations; and clinician experience and expectations. Subcision may be used for the treatment of:

1. Depressed distensile scars (due to acne, trauma, surgery)

2. Depressed bound down scars (due to acne*, varicella (chickenpox), trauma, surgery)

3. Depressed skin grafts

4. Wrinkles

5. Cellulite dimples

*excluding deep ice-pick scars

Results may vary patient to patient.
