What primarily occurs during the maturation/remodeling phase of full-thickness wound repair?

1. Wound infection control

2. Modification of scar tissue to produce a mature scar

3. Healing of epidermis only

4. Increased vascularity

The correct answer is: Modification of scar tissue to produce a mature scar

During the maturation/remodeling phase of full-thickness wound repair, the primary process involves the modification of scar tissue to produce a mature scar. This phase typically begins weeks after the initial injury and can last for months to years. During this phase, collagen is remodeled and restructured, increasing its tensile strength and improving the appearance of the scar. The collagen fibers, initially laid down in a random configuration for temporary support, begin to align and organize along tension lines in the skin, resulting in a firmer and more flexible scar that is closer to the original tissue. The reduction in vascularity also occurs as the excess blood vessels formed during the earlier phases of healing regress, contributing to the transition from a red, raised scar to a flatter, lighter scar over time. This phase is crucial for the restoration of the skin’s strength and functionality. Though wound infection control is essential in earlier stages of healing, it is not a primary focus during this late phase. Similarly, while the healing of the epidermis may occur during other stages, the maturation/remodeling phase is more about refining scar tissue rather than simply healing the superficial layers. Therefore, the correct understanding of this phase centers on the maturation of the scar tissue produced.
