What is the primary difference between a split-thickness skin graft (STSG) and a full-thickness skin graft (FTSG)?

  1. An STSG includes only epidermis, while an FTSG includes only dermis
  2. An STSG takes epidermis plus part of dermis; an FTSG takes full dermis and epidermis
  3. An FTSG can be expanded like a mesh, whereas an STSG cannot be meshed
  4. There is no meaningful structural difference between the two graft types
Show answer and explanation

Correct answer: An STSG takes epidermis plus part of dermis; an FTSG takes full dermis and epidermis

STSG removes the epidermis plus part of the dermis, whereas FTSG removes the full dermis and epidermis, leading to different outcomes and donor-site costs.
