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 primary intention?

The end result of healing by primary intention is (in most cases) a complete return to function, with minimal scarring and loss of skin appendages. Figure 1 – A surgical wound, closed by sutures. This is an example of healing by primary intention.

What are examples of secondary intention?

Secondary intention happens when a wound has a great deal of lost tissue, or is extensive and the edges can’t be brought together. An example would be a pressure ulcer.
