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

[zē′plas′tē]
a method of surgical revision of a scar or closure of a wound using a Z-shaped incision to reduce contractures of the adjacent skin. See also Y-plasty.

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-plasty

(z-plas'te)
The use of a Z-shaped incision in plastic surgery to relieve tension in scar tissue. The area under tension is lengthened at the expense of the surrounding elastic tissue.

Z-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.

n a surgical procedure using the transposition of tissue flaps to ensure the release of contractures, as in the repair of a cleft lip or in ankyloglossia.
