[Esthetic refinements in cheiloplasty or the use of the V, W, X, Y, Z technics].

Classically, V-wedge excision of the lip allows direct closure of defects less than a third of its width.

To avoid these aesthetic complications modified incision should be made: W followed by a V-Y advancement closure, completed by a Z plasty on the vermilion.
