To improve the outcomes of secondary cleft lip deformity correction, two different invisible incisions, vermilion incision and under-nose incision were designed and compared. It was noted that vermilion incision was quite suitable for prolabial reconstruction, especially for labial peaks adjustment and rebuilding of the anatomic structures including philtrum ridges and fossa. While with under-nose incision, both prolabial and cleft nose deformities could be easily corrected. Both of the invisible incisions could enrich the surgical design inventory and had important value in secondary cleft deformities correction.
