Abstract:
Using a cross lip vermilion flap for upper red lip reconstruction in cases other than whistle deformity in patients with cleft lip can lead to donor site morbidity. If the practitioner performs primary closure of the mucosa in lower vermilion after flap harvesting, the width and height of lower lip are reduced, which results in an increased lower incisor tooth show. Using free fat grafting is an effective method for reducing donor site morbidity in the lower lip following cross lip vermilion flap harvest.
