Aesthetic lip splits.

Both upper and lower lip splits, usually with osteotomy of the underlying jaw, improve access to the deep structures of the head and neck. A simple modification to the midline lip split is to incorporate a chevron in both the peri-oral skin and vermilion margin. The advantages are: accurate wound closure, no straight line contracture and a broken line of the peri-oral scar. This improves the aesthetic result of the healed lip.
