Z-plasty
Z-plasty [ze´plas-te] repair of a skin defect by the transposition of two triangular flaps of adjacent skin, for relaxation of scar contractures. Called also zigzagplasty. Z-plasty, showing the direction of relaxed skin tension lines (arrow), desired position of final scar (dotted line), and the two flaps to be juxtaposed (a, b). From Dorland's, 2000.Z-plas·ty (plas'tē), 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.Z-plasty (zē′plăs′tē)n. A surgical procedure to elongate a contracted scar or to rotate tension 90° in which the middle line of the Z-shaped incision is made along the line of greatest tension or contraction, and triangular flaps are raised on opposite sides of the two ends and then transposed.Z-plasty Surgery A surgical incision that lengthens a zone of skin or a muscle, 'breaking up' a linear scar or repositioning an incision to a line of least tension. See Y plasty. Z-plas·ty (plas'tē) Surgery to elongate a contracted scar or to rotate tension 90 degrees; the middle line of a Z-shaped incision is made along the line of greatest tension or contraction, and triangular flaps are raised on opposite sides of the two ends and transposed.

The area under tension is lengthened at the expense of the surrounding elastic tissue. See: illustration; tissue expansion, soft; W-plastyillustrationZ-plasty A plastic surgical technique for relieving skin tension or releasing scar contracture. Adjacent, V-shaped flaps, pointing in opposite directions are cut, undermined, freed and their points transposed.Z-plas·ty (plas'tē) Surgery to elongate a contracted scar or to rotate tension 90 degrees; the middle line of a Z-shaped incision is made along the line of greatest tension or contraction, and triangular flaps are raised on opposite sides of the two ends and transposed.
