BACKGROUND: Although the Z-plasty has been used on the lips in various applications, its novel utility in improving classic vertical (radial) lip reconstruction has not been described previously. OBJECTIVE: To demonstrate the advantages of Z-plasties in vertical lip reconstruction, to explore six distinct causes of lip deformities that arise during reconstructive surgery and how those complications can be avoided by employing traditional Z-plasties or a new modification we term the "sliding Z-plasty," and to provide an entirely original first-time analysis of the geometry and physical dynamics of lip reconstruction. MATERIALS AND METHODS: We explored the planning and execution of lip reconstruction using traditional Z-plasties and a new sliding Z-plasty modification. This analysis uses case reports, original illustrations, and an in-depth discussion of the spatial dynamics of lip reconstruction. CONCLUSION: Traditional or sliding Z-plasties can improve the final outcome of vertical lip reconstruction while avoiding or mitigating six distinct potential complications associated with classic repairs.
