Medical Term:

Z-plasty

Pronunciation: plas′tē

Definition: Technique to increase soft tissue length along a selected axis; change the direction of a malaligned scar 90 degrees; obliterate or create a web or cleft (as in syndactyly or thumb-web contractures); or alter surface contour. The central limb is located along the malaligned scar or the site of greatest tension; opposing flaps are constructed at each end (or at intervals) along the central limb at angles of 30–90 degrees depending on clinical circumstances. The flaps are elevated and transferred, reorienting the central limb by 90 degrees.
