2 ways cutaneous wounds are healed |
1. Primary intention 2. Secondary intention |
|
|
Features of healing by secondary union (secondary intention) |
1. More intense inflammation 2. Wound contraction (myofibroblasts which decreases size of wound) 3. Larger scar formed 4. More granulation tissue formed |
|
|
2 category of factors that influence wound healing |
1. Systemic 2. Local |
|
|
4 systemic factors that affect wound healing |
1. Nutrition (e.g. protein, vitamin C and zinc) 2. Metabolic status (e.g. DM) 3. Circulatory status (e.g. atherosclerosis) 4. Hormones (e.g. steroids can block inflammation) |
|
|
4 local factors that affect wound healing |
1. Mechanical factors 2. Infection 3. Foreign material 4. Size, location and type of wound |
|
|
3 types of wound healing complications |
1. Deficient scar formation (wound dehiscence) 2. Excessive formation of repair components (hypertrophic scars, keloid scars and proud flesh) 3. Excessive contraction (contractures) |
|
|
Difference between hypertrophic and keloid scars? Similarity? |
Hypertrophic stays within the boundary of the wound Keloid scars grow beyond the boundary of the wound
Both are excess deposition of type III collagen |
|
|
Excessive granulation tissue is what form of deficient wound healing? |
Proud flesh |
|
|
Fibrous union in bone is called? |
Callus |
|
|
What is leucoma? |
Loss of transparency in the cornea Transparency is due to collagen arrangement in middle layer of corneal stroma. Injury to stroma causes it to become opaque and leucoma results (disturbs vision). |
