16 Questions
Why does a high length-to-width ratio decrease the likelihood of flap survival?
Blood supply will not reach the distal end of the flap.
What is the basic technique known as the single pedicle advancement flap used for?
To close large wounds with one flap.
Why are two single pedicle flaps considered safer than one large flap for closing larger wounds?
They provide better coverage over the defect.
In which flap technique does the coverage depend on stretching the skin over the defect?
V-Y advancement flap
What is the purpose of axial pattern flaps in surgical procedures?
To provide a new blood supply to ensure flap survival
Which artery is the best-described for axial pattern flaps?
Caudal superficial epigastric artery
Why must axial pattern flaps have consistent landmarks?
To have a direct cutaneous arterial supply
What is the purpose of using free skin grafts?
For cases with massive tissue loss like large burns or degloving injuries
What factor is vital for the survival of all skin flaps and grafts?
Recipient bed free of debris, infection, and necrotic tissue
What may cause skin edema in a flap immediately after inosculation?
Venous return before arterial supply
Why should purple color not be used as a predictor of viability in flaps?
'Purple skin' can sometimes be viable
What is the significance of assessing color, warmth, sensation, and bleeding in determining flap viability?
They are objective measures that accurately assess flap viability
Why might contused, purple skin sometimes be viable?
'Purple' may not indicate tissue death
What may not remain viable if laid over squamous epithelium, denuded bone, cartilage, or tendon?
Free skin grafts
What methods are NOT accurate in assessing the viability of flaps?
Anastomosis with recipient bed vessels
In which type of surgeries are free skin grafts typically used?
Cases involving massive tissue loss
