Principle of Plastic Suregry

  1. Geometric Principle of the Z-Plasty
  2. The Z-plasty is an ingenious principle that can be applied to revise and redirect existing scars or to provide additional length in the setting of scar contractor.
  3. The Z-plasty involves the transposition of two triangular flaps.
  4. The limbs of the Z must be equal in length to the central limb but can extend at varying angles (from 30–90 degrees) depending on the desired gain in length.
  5. The classic Z-plasty has an angle of 60 degrees and provides a 75% gain in length of the central limb by recruiting lateral tissue.

  1. Skin Flaps:
    1. Unlike a graft, a flap has its own blood supply.
    2. Flaps are usually needed for covering recipient beds that have poor vascularity; reconstructing the full thickness of the eyelids, lips, ears, nose, and cheeks; and padding body prominences (i.e., for bulk and contour).
    3. A skin flap consists of skin and subcutaneous tissue that are transferred from one part of the body to another with a vascular pedicle or attachment to the body being maintained for nourishment.
    4. If the flap is pedicled, it is important that the pattern is cut to include the base of the flap and that it is made a little longer and wider than needed.
    5. The pattern is then tried again, being certain each time that it is shifted so that the base is held in a fixed position and not allowed to shift with the flap.
    6. The final pattern must be larger than needed, particularly its length, to avoid undue tension and kinking.
    7. Planning a transposition or rotation flap requires special attention to ensure that the most distal part of the flap is of sufficient length.
