Which is a benefit of using omentum as a graft?
 
  a. Will resorb into tissue when grafted
  b. Does not usually require a split-thickness skin graft
  c. Has very few blood vessels for anastomosis
  d. Helps localize and control infection

Question 2

What process increases the surface of the dermal-epidermal layer to create a skin flap?
 
  a. Rotational flap
  b. Tissue expansion with a tissue expander
  c. Subcutaneous flap
  d. Arterialized flap

Answer to Question 1

ANS: D
A free graft of omentum can be used to provide contour in a soft tissue defect in the face or neck, to resurface an area such as the scalp, to provide vascular support for bone and skin grafts around prosthetic materials, and to control wound infection, such as in the chest wall. Omentum will localize inflammation and wall off infection. It will not resorb when grafted. Omentum resected from the peritoneal cavity can be transplanted to an avascular area if sufficient blood vessels are available for microvascular anastomoses to the gastroepiploic artery and vein in the graft. Split-thickness skin grafts cover the omental graft.

Answer to Question 2

ANS: B
A tissue expansion device is implanted subcutaneously to close a defect. This process allows the dermis to stretch and thin out while the epidermis duplicates itself.
