What causes scars?

Stuart A. Linder, MD
Plastic Surgery

A scar can be defined as a mark left by a healed wound, sore or burn. The etiology of a scar include: traumatic laceration, burns, radiation damage, lasers, pressure necrosis, and crush injury. When wounds heal by secondary intention, without suture closure, a mark will be forever left behind. Types of scars include: keloids, hypertrophic scars, acne scars, hyper/hypo-pigmentation, and widespread scars. Scars are the inevitable tradeoff of my practice as a Plastic Surgeon.
