Over 80% of adults around the world get affected by acne at least once in their lifetime. It appears most commonly on the face, chest, neck, and back area. If left untreated, acne can damage your skin leading to scarring.
The specific surgical techniques for the management of post-acne scarring include Subcision, punch techniques, and Dermal grafting. Other non-surgical procedures include Microneedling, TCA CROSS, fractional lasers, MNRF, and dermal fillers.
Subcision: The procedure helps by releasing the fibrous strands that pull down the overlying tissue in the acne scar. The scarred area is marked and a needle is inserted at the periphery of the scarred area and gently swept across the site to break the bands. Treatment can be repeated up to two to three successive treatments. Swelling and hardness of treated area over face, bluish discoloration may be present which might persist for 5–7 days.
Punch techniques: Punch techniques help by removing a pitted acne scar with a small rim of normal tissue, which heals by new collagen synthesis and epithelization. The punch techniques include: punch excision and secondary intention healing, punch excision and closure, punch flotation or punch elevation and punch replacement grafting.
Dermal grafts: A dermal graft acts as a filler material for treating depressed scars. It is a skin graft from which the epidermis and subcutaneous fat have been removed. Donor tissue is taken from behind the ear using an appropriate-size punch. A small slit is made to insert the graft under the depressed scar which is closed later.
Other acne scar surgeries include dermabrasion, soft tissue augmentation, scar revision & autologous fat transfer.
