The remodeling (maturation) phase of wound healing can last up to:
Answer: 2 years
The remodeling phase involves collagen cross-linking and scar maturation and can continue for up to 2 years following initial wound closure.
How does low-level laser therapy (LLLT) affect fibroblast activity in wound healing?
Answer: LLLT stimulates fibroblast proliferation and collagen synthesis, accelerating tissue repair
Low-level laser therapy stimulates fibroblast proliferation and increases collagen synthesis through photobiomodulation, directly accelerating the tissue repair process.
Which wavelength range is considered most effective for promoting wound healing in deep tissue using laser therapy?
Answer: 630–1000 nm (red to near-infrared range)
The 630–1000 nm therapeutic window (red to near-infrared) penetrates tissue optimally and interacts with cytochrome c oxidase to stimulate cellular energy production and wound healing.
What is wound contraction and which cell type drives this process?
Answer: It is the pulling together of wound edges, driven by myofibroblasts
Wound contraction is the mechanical drawing together of wound margins, primarily driven by myofibroblasts—differentiated fibroblasts with smooth-muscle-like contractile properties.
A wound with slough and necrotic tissue is considered to be in which wound healing state?
Answer: A stalled or chronic wound requiring debridement before laser therapy can be maximally effective
Slough and necrotic tissue indicate a stalled wound; debridement is typically required to remove non-viable tissue before laser therapy can optimally stimulate healing.
In diabetic wound healing, why is laser therapy particularly beneficial?
Answer: It compensates for impaired microcirculation and cellular dysfunction by enhancing cellular energy (ATP) production and angiogenesis
Diabetes impairs microcirculation and cellular metabolism; laser therapy's ability to boost mitochondrial ATP production and stimulate angiogenesis directly addresses these deficits.
