Delayed primary closure is a combination of the aforementioned types of wound healing. It is often intentionally applied to lacerations that are not considered clean enough for immediate primary closure. The wound is left open for 5-10 days; then, it is sutured closed to decrease the risk of wound infection, while also allowing expedited wound healing. Improved blood flow at the wound edges, which develops increasingly over the first few days, is another benefit of this style of wound healing and can be associated with progressive increases in resistance to infections.
