A technique that is used in plastic surgery to change the direction of a pre-existing scar so that it can be hidden in natural skin creases, or to relieve skin tension caused by the contracture of a scar.
Z-plasty is especially useful for revising unsightly scars on the face and for releasing scarring across those joints, such as on the fingers or in the armpits, that may restrict normal movement or cause deformity.
