PLASTIC SURGERY Flashcards
for ideal scar how should the incision run?
parallel to RSTL
how should the incision be made for optimal healing and minimal scarring?
incision must be perpendicular to skin and not oblique
belly of blade should be used
how are dog ears removed?
cut toward redundant skin and then pull and cut away excess
eliminate dead space
what are the stages of skin graft healing?
plasmatic imbibition:24-48 hrs
inoculation and capillary
revascularization
inhibition phase time?
24-48 hrs
when does inoculation phase end?
5-7 days
what is true about skin grafts?
resembles donor skin
more durable
less contracture
higher failure rate
thinner the graft, the better or worse the take?
thicker the graft, the better or worse the function?
better
better
what makes the graft fail?
movement
seroma
infection
what does a whole skin graft entail?
qualities
epidermis + complete dermis
resembles donor skin
more durable
less contracture
higher failure rate
what is a split skin graft?
qualities
epidermis + variable quantity of dermis
better healing rate
more contracture
donor site heals easier
where to get a split skin graft?
thigh!!
what closes linearly?
V to Y
where can you not put a split skin graft?
bone, tendon
what allows for easier closure when removing lesion?
make the ellipse 3x longer than wide
angles determine the amount of lengthening, what is percent for the following angles?
30
45
60
25%
50%
75%
about what structure is the first to hold down graft?
collagen
fibrin
hemoglobin
?
what are the two types?
passive
active
considerations when removing the drain?
when drainage stops or obstructed
72 hrs is max for keeping drain in place or infection
what is the AO technique?
drill near drill far countersink measure tap screw
