Which healing type is typically associated with the fastest healing and least scar when a clean wound is closed with sutures immediately?

Which healing type is typically associated with the fastest healing and least scar when a clean wound is closed with sutures immediately?

• A. Primary intention healing
• B. Secondary intention healing
• C. Tertiary intention healing
• D. No healing

Answer: (A)

When a clean wound is closed promptly with sutures, it heals by primary intention. The edges are neatly approximated, there’s minimal tissue loss, and the wound gap is small. This allows epithelial cells to migrate quickly across the closure and collagen to remodel with little inflammatory tissue or granulation filling, resulting in the fastest healing and the smallest scar. If the wound edges aren’t brought together or there’s more tissue loss, healing occurs by secondary intention. It relies on granulation tissue filling a larger gap, wound contraction, and longer epithelialization, which takes more time and typically leaves a larger scar. Delayed closure, or tertiary intention, leaves the wound open for a while to reduce infection risk and then closes it later. This approach has a longer healing course than primary intention and can produce more scar formation than immediate primary closure, though it may reduce infection risk in contaminated wounds. No healing isn’t a viable option for repairing tissue.
