Full-thickness skin grafts have a better appearing texture,
thickness and color than split-thickness. The disadvantages is that they
are best placed in a well vascularized bed and should be no more than 2 cm in
size. The reason for this is that full-thickness skin grafts receive
the new blood supply from the margins of the graft as a split-thickness graft
receives its blood supply form the undersurface of the graft.
Full-thickness skin grafts are ideal for covering small defects on the nose and
ears. The post-auricular skin provides excellent donor tissue with a good
color match and a donor scar which is hidden.
A full-thickness skin graft is also less likely to undergo wound
contracture which can cause a significant cosmetic defect on the face. The
donor site should be closed within three days to help prevent wound contracture
from occurring. The graft is harvested by hand using a scalpel.
After graft placement, a bolster dressing is often applied and left in place for
approximately one week. If the graft does not take 100% often the
underlying tissue and dermis survives and will re-epithelialize the surface.
A split-thickness skin graft is more delicate but can cover a larger surface
area. It is harvested using a dermatome, which is a shaving instrument
with a very shape blade. Graft thickness varies from 0.005 to 0.03 inches.
An intermediate thickness graft would have a thickness of 0.014 inches.
The grafts are sewn in place and a bolster or dressing is used to stabilize the
graft and prevent shearing.
