There are many techniques for scar revision in plastic surgery but one of the most well known is that of a Z-plasty. It is a technique for either improving the appearance of a scar (by changing the line of tension) or improving its function by contracture release. (elongating the scar) It is based on the use of two triangular skin flaps cut along a central portion of the scar. Based on the angles that the Z limbs are cut determines how much scar lengthening occurs. It was first described in 1856 and was initially used for scar problems around the eyelids and mouth, for which it is still useful today. While the geometry of a Z-plasty has a lot of appeal, it is an infrequent scar revision technique that is useful only for specific type scars. There are many other scar revision methods that are more widely used.
