On this page you will find the design of a Z-plasty facial flap.
- Double transposition of triangular flaps. See fig 1
- Used in scar revision the z-plasty can; change the direction of a scar, interrupt scar linearity, lengthen scar and release contractures
- Can be designed as a single or multiple. See fig 2
- A central limb and two peripheral limbs in the shape of a Z.
- All three limbs are identical in length.
- The scar or area with contractures makes up the central limb of the Z.
- Can be designed with angles between 30°-90° but 60° is the most common.
- The greater the angles = greater gain in length = larger standing cutaneous defect.
- When the flaps are raised and transposed, the direction of the central limb will change. In a 60°angled z-plasty it will change approximately 90°.
