What is a major characteristic associated with third intention wound healing?

The characteristic of delayed closure with granulated surfaces is central to third intention wound healing, also known as tertiary intention healing. This method is often utilized when a wound is left open for a certain period to allow for proper drainage and to reduce the risk of infection. During this time, granulation tissue—a vital component of the healing process characterized by new connective tissue and tiny blood vessels—forms.

Once the status of the wound is deemed adequate, typically when the risk of infection has decreased, the wound can be closed surgically. This technique is particularly useful in cases where initial closure is not feasible or safe due to contamination or the presence of significant edema. By allowing the formation of granulation tissue, the healing process is enhanced, facilitating better closure upon surgical intervention later.

This contrasts with direct closure, which is associated with primary intention healing, and secondary intention healing, where the wound heals naturally without surgical closure.
