ASPS Reconstructive Surgery Principles & Techniques 2

Question 1

Which flap classification describes tissue that retains its original blood supply throughout transfer?

Accepted Answer

Pedicled flap

Answer

A pedicled flap maintains its native vascular pedicle during transfer, unlike a free flap which requires microvascular anastomosis.

Question 2

In the reconstructive ladder, which option represents the most complex level of reconstruction?

Accepted Answer

Free tissue transfer

Answer

Free tissue transfer sits at the top of the reconstructive ladder, requiring microvascular anastomosis and offering the greatest versatility.

Question 3

What is the primary advantage of a musculocutaneous flap over a fasciocutaneous flap for infected wounds?

Accepted Answer

Superior bulk for obliteration of dead space and infection control

Answer

Muscle has robust vascularity that enhances antibiotic delivery and host defense, making it superior for infected or contaminated wounds.

Question 4

The 'zone of injury' concept in trauma reconstruction refers to:

Accepted Answer

Tissue surrounding the wound that may have compromised vascularity

Answer

The zone of injury extends beyond visible wound edges and may contain traumatized tissue with impaired perfusion that can compromise flap survival.

Question 5

Which nerve coaptation technique involves trimming nerve ends to healthy fascicles and using fibrin glue or sutures without tension?

Accepted Answer

Neurorrhaphy

Answer

Neurorrhaphy is direct nerve repair by coaptation of nerve ends, requiring tension-free alignment of fascicles for optimal axon regeneration.
