What does the term 'dehiscence' refer to in wound healing?

1. Delay in closure of a wound

2. Partial or complete separation of the layers of a surgical wound

3. Formation of excess granulation tissue

4. Infection in the wound area

The correct answer is: Partial or complete separation of the layers of a surgical wound

Dehiscence refers to the partial or complete separation of the layers of a surgical wound, which can occur when the tension on the wound edges is too great or if there are factors that impede healing, such as infection or inadequate suturing. This term is particularly important in surgical contexts, as it indicates that the wound has not remained closed as intended following a surgical procedure. In wounds, proper healing typically leads to the layers coming together and forming a stable closure. When dehiscence occurs, it can result in complications, such as increased risk of infection, delayed healing, and further surgical intervention may be required to repair the wound. Thus, understanding dehiscence is crucial for monitoring surgical wounds and ensuring proper postoperative care. While delays in closure of a wound, excess granulation tissue, or infection may contribute to the overall wound healing process and could be associated with dehiscence, they do not define the term itself.
