The Z-plasty technique is a modification of the wedge labiaplasty. It is performed when there is excessive labial tissue where the labia minora inserts at the prepuce and/or the perineum and in cases of asymmetry or scarring.
It is a surgical technique in which a series of triangular incisions are made on the labia minora, followed by repositioning the labial tissues in a zig-zag pattern.
