Wound reconstruction Flashcards
an elliptical incision of a round mass allows…
closure without deformity
how do you class a flap?
- Blood supply: random cutaneous vs. direct cutaneous artery
- Location: distant or Local
List 6 simple skin flap techniques
- Advancement skin flaps
- Rotation flap
- Bipedicle advancement flap/ V-Y plasty
- Transposition flap
- Flank flaps
- Z plasty
Advantages of a single pedicle advancement flap
- no secondary defect
- utilises loose skin at wound edge
what is the length the of arc in a rotation skin flap?
4x the defect
in what locations are rotation skin flaps useful?
ears, eyelids, maxilla
how many suture lines are there when using a bipedicle advancement flap?
2-3 - your initial incision + you extra tension releasing incision (potentially two if you do one on either side of the surgical site incision)a
when the V-Y plasty useful?
eyes and ears
what blood supplies a inguinal flap?

thoracodorsal a.
when are axilla and inguinal ‘flank’ flaps useful?
proximal limb and trunk defects
give two types of distant flaps?
single (hinge) and bipedicle (pouch) flaps
describe how distant flaps are staged procedures
they require a 2 week period for cut down
when are free skin grafts indicated?
Defects cannot be closed primarily with a local technique and where second intention healing is undesirable
Graft acceptance depends on 3 things
- Plasmatic imbibition
- Inosculation
- Revascularisation
