This case report describes the treatment of a girl, age 11 years 10 months, with a cleft lip and palate and a postsurgical scar. The clinical examination showed a concave profile, a retrusive maxilla, an asymmetric face, severe dental crowding, a Class III dental relationship, and a complete dental crossbite. Maxillary expansion and distraction, chincap, and high-pull headgear were used to moderate the skeletal discrepancy. These approaches, combined with tooth extraction and fixed orthodontic appliances, finally established a functional and esthetic occlusal relationship, normal overjet and overbite, and a well-balanced facial appearance.
