ASPS ASPS Wound Healing & Tissue Management 2

Question 1

Negative pressure wound therapy (NPWT) promotes healing primarily by:

Accepted Answer

Removing excess fluid and promoting granulation tissue formation

Answer

NPWT applies sub-atmospheric pressure to remove excess exudate, reduce edema, and stimulate granulation tissue through mechanical stretch.

Question 2

Which factor is MOST likely to impair wound healing in a pre-operative plastic surgery patient?

Accepted Answer

Poorly controlled diabetes mellitus

Answer

Hyperglycemia impairs neutrophil function, reduces collagen synthesis, and compromises angiogenesis, significantly delaying wound healing.

Question 3

A full-thickness skin graft requires a well-vascularized recipient bed primarily to:

Accepted Answer

Allow imbibition and inosculation for graft survival

Answer

Full-thickness grafts initially survive by imbibition (passive nutrient absorption), then inosculation (vascular connection), requiring a healthy recipient bed.

Question 4

The 'delay phenomenon' in flap surgery refers to:

Accepted Answer

Conditioning a flap to increase its vascularity before transfer

Answer

The delay phenomenon involves partial interruption of a flap's blood supply to induce adrenergic denervation and improve perfusion before final transfer.

Question 5

Which tissue type has the LEAST capacity for regeneration after injury?

Accepted Answer

Cardiac muscle

Answer

Cardiac muscle cells (cardiomyocytes) have extremely limited regenerative capacity and injured tissue is replaced by fibrous scar, not functional myocardium.
