Secondary intention wound healing is a process of natural wound healing that occurs when a wound is left open to heal without surgical closure or the use of sutures. It is typically used for larger, deeper wounds that cannot be closed primarily or when primary closure is not desired or possible.

In secondary intention healing, the wound is allowed to heal from the bottom up through the formation of granulation tissue, which consists of new blood vessels, fibroblasts, & inflammatory cells. The wound is left open & allowed to fill in gradually with the granulation tissue, which eventually contracts & forms a scar.

During the healing process, the wound is typically cleaned & dressed regularly to maintain a moist environment, promote the growth of new tissue, & prevent infection. The healing time for wounds healing by secondary intention can be longer compared to wounds closed with sutures or surgical techniques. The final outcome may also result in a larger scar or more noticeable tissue remodeling.

It’s important to note that the decision to use secondary intention healing is typically made by your vet based on factors such as the size, depth, & location of the wound, as well as the overall health of the patient.
