What is healing by tertiary intention?
Healing by Tertiary Intention Tertiary healing (third intention) is delayed primary wound healing after 4–6 days. This occurs when the process of secondary intention is intentionally interrupted and the wound is mechanically closed. This usually occurs after granulation tissue has formed.
What types of wounds heal by secondary intention?
Examples of wounds healing by secondary intention include severe lacerations or massive surgical interventions. Healing by tertiary intention is the intentional delay in closing a wound. On occasion, wounds are left open (covered by a sterile dressing) to allow an infection or inflammation to subside.
