What is the difference between wound excision and wound debridement?

Wound excision involves the surgical removal of a portion of tissue, including surrounding skin, to treat infected or necrotic wounds, often aiming to promote healing and restore function. In contrast, wound debridement refers to the process of cleaning a wound by removing dead, damaged, or infected tissue, debris, and foreign materials, which can be done through various methods such as mechanical, enzymatic, or autolytic techniques. While both aim to improve wound healing, excision typically involves the removal of larger areas of tissue.
