Wound Healing Flashcards
(17 cards)
How is wound healing classified?
What is meant by wound healing by primary intention?
What about secondary intention?
Go through the stages of wound healing in detail.
Are these stages considered healing by primary or secondary intention?
Include the estimated timeframe that each stage may include
What is shown in this image
Hypertrophic scar
What is shown in this image
Keloid scar
Long case question:
What factors delay wound healing?
List the components of the reconstructive ladder
Define a skin graft
What are the two types?
Subunit of skin transferred from one area to another without its own blood supply
Split thickness graft
Full thickness graft
What surgical instruments are used to obtain a skin graft
Why would you use a full thickness graft over a split thickness graft?
Full thickness grafts are used to cover more sensitive areas or cosmetically important areas with correct pigmentation
Compare and contrast Split and full thickness grafts including:
1) Layers involved
2) Typical harvesting sites
3) Donor site wound Healing type
To say it properly
e.g.
Split thickness graft involves harvesting the epidermis and variable amounts of dermis via an Air-powered dermatome +/- Skin graft mesher (e.g. for burns)
These are typically harvested from the thigh and buttocks and requires a reasonable blood supply at the recipient site for graft take
What is “Graft Take”?
Successful attachment and integration of transplanted skin graft
Would you use a graft or a flap for pressure ulcers?
The answer should be “depending on depth etc…”
Most of the time, its flap
What is a flap?
Subunit of tissue transferred from one area to another with its own blood supply => recipient blood supply not crucial
List the indications for the use of a flap over a graft?
1) Functional and aesthetic considerations (face, hand, foot, breast, APR)
2) Exposed critical structures (bone, nerves, vessels)
3) Large, deep or structurally weak defects (pressure ulcer reconstruction)
4) Irradiated or contaminated wounds
5) Areas of movement (Joint surfaces)
Think areas and circumstances where there would be poor wound healing or aesthetics
Flaps can either be classified by
1) Blood supply (2)
2) Location (3)
State them and briefly explain what they are
Compare and constrast grafts vs flaps
Large table so say it as you would on a long case and check to see what you can add
