⭐ High-Yield Facts for Exam

  • STSG = epidermis + part dermis; better take, more contraction.
  • FTSG = full dermis; less contraction, better match.
  • Grafts depend on recipient bed vascularity.
  • Pedicled flap keeps its vascular base.
  • Free flap = microvascular transfer.

Skin Grafts & Flaps

Skin Grafts (no own blood supply — depend on the bed)

  • Split-thickness skin graft (STSG) — epidermis + part of dermis; takes more reliably but contracts more.
  • Full-thickness skin graft (FTSG) — epidermis + full dermis; less contraction, better colour/texture match, but needs a well-vascularised bed.

Flaps (carry their own blood supply)

  • Pedicled flap — remains attached to its vascular base.
  • Free flap — detached and reanastomosed microsurgically at the recipient site (e.g., radial forearm, fibula for mandible reconstruction).

Exam Tips ⭐

STSG = better take, more contraction; FTSG = less contraction; free flap = microvascular transfer.

📝 Practice MCQs — Skin Grafts & Flaps

Q1. Which graft contracts more after healing?
A. Full-thickness
B. Split-thickness
C. Composite
D. Both equal
Show Answer
✅ Answer: B
Split-thickness grafts undergo more secondary contraction.
Q2. A free flap differs from a pedicled flap in that it:
A. Has no blood supply
B. Is detached and reanastomosed microsurgically
C. Is always skin only
D. Cannot be used in the face
Show Answer
✅ Answer: B
Free flaps are transferred and re-anastomosed microvascularly.
Q3. Which provides a better colour/texture match with less contraction?
A. Split-thickness graft
B. Full-thickness graft
C. Meshed graft
D. None
Show Answer
✅ Answer: B
Full-thickness grafts give better match and less contraction.
