Improving the Results of Cross Lip Vermilion Flap in Cleft Patients.

Cross lip vermilion flap is a myomucosal flap that uses lower red lip to augment deficient upper lip vermilion. Technical note that helps in imitating upper lip tubercle structure is presented. Appropriate patient selection to prevent unfavorable results such as color mismatch, local vermilion excess, and lower lip thinning are presented. Indirect benefits of this flap for decreasing upper incisor tooth show and better balance of upper/lower lip thickness are discussed.
