Q

What are the benefits of a full-thickness skin graft

over a split-thickness skin graft?

A

● Better color and texture match
● Less scar contraction
● No need for additional equipment (dermatome) for
harvest
● Easier donor-site wound care and less contour irregularity

2
Q

What are the most common head and neck donor
sites for full-thickness skin grafts used in facial
reconstruction?

A

Upper eyelid, preauricular or postauricular, supraclavicular,
melolabial fold, and forehead

3
Q

How do full-thickness skin grafts survive initially during the first 24 to 48 hours?

A

Plasma imbibition: the diffusion of nutrition from the fluid at the recipient site, after which capillary inosculation takes place at 48 hours

4
Q

What are the primary causes of skin graft failure?

A

Infection, shearing, fluid accumulation between the graft and recipient bed

5
Q

What is the function of a bolster dressing over a skin graft?

A

It ensures maximal graft to recipient bed contact and

decreases shearing forces that might affect graft survival.
