Methods: cross-sectional descriptive study, clinical examination and on the plaster cast and frontal cephalometric. Results: The highest Angle III rate is accounted for 50 percent in the right and 60,7 percent in the left. The bilateral posterior crossbite rate is accounted for 71,4 percent and was significantly higher than unilateral posterior crossbite in isolated Cleft Palate (CP) and complete Bilateral Cleft Lip and Palate (BCLP).
