What is the significance of granulation tissue growing above skin level?

1. Indicates infection

2. Suggests poor vascularization

3. Shows effective healing

4. Demonstrates tissue necrosis

The correct answer is: Shows effective healing

Granulation tissue that grows above skin level is a sign of effective healing. Granulation tissue is composed of new connective tissue and microscopic blood vessels that form on the surface of a wound during the healing process. When this tissue protrudes above the skin's surface, it indicates that the body is actively building new vascular and connective tissue, which is essential for wound repair. This protrusion often reflects an adequate blood supply to the area, allowing for the delivery of necessary nutrients and oxygen that promote healing. The formation of granulation tissue is a positive indicator, as it plays a critical role in wound healing, bridging the gap between tissue loss and promoting eventual re-epithelialization. As healing progresses, this granulation tissue will typically be replaced by mature scar tissue, if the wound continues on an optimal healing trajectory.
