Why does a high length-to-width ratio decrease the likelihood of flap survival?
Why does a high length-to-width ratio decrease the likelihood of flap survival?
- The flap becomes too heavy for the recipient bed.
- The skin tension decreases with a higher ratio.
- Blood supply will not reach the distal end of the flap. (correct)
- The vascular plexus becomes more robust.
What is the basic technique known as the single pedicle advancement flap used for?
What is the basic technique known as the single pedicle advancement flap used for?
- To close large wounds with one flap. (correct)
- To create a double pedicle flap.
- To enhance blood circulation in the recipient bed.
- To move skin to cover an adjacent defect.
Why are two single pedicle flaps considered safer than one large flap for closing larger wounds?
Why are two single pedicle flaps considered safer than one large flap for closing larger wounds?
- They prevent revascularization from the recipient bed.
- They increase the risk of failure due to tension.
- They reduce the blood supply to the recipient bed.
- They provide better coverage over the defect. (correct)
