Z plasty principle is one of the most versatile concepts in
plastic surgery. Its application is mainly in scar revision. It is
designed to accomplish three things:
- - change direction of scar
- - interrupt scar line (break tension lines)
- - lenghten scar (overcome contraction)
Proper planning is essential. Classic description is a central
limb and two peripheral limbs in the shape of a Z. All three limbs are
identical in length, the angle is 60 degrees. It is only possible if
there is loose skin at right angles to the scar.
