What is meant by primary intention?
Healing by first (primary) intention, or primary closure, refers to the healing of a wound in which the edges are closely re-approximated. In this type of wound healing, union or restoration of continuity occurs directly with minimal granulation tissue and scar formation.
What is an example of secondary wound healing?
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.
