Cephalometric findings in two cases with unrepaired bilateral cleft lip and palate.

Two cases with unoperated bilateral cleft lip and palate were examined clinically and cephalometrically and compared to matched normals. The findings indicate a severe premaxillary skeletal protrusion which results in a maxillary-mandibular discrepancy. The maxillary incisor inclination was acceptable, while the mandibular incisors were relatively more lingually inclined in the cleft group. Surgical management of one case necessitated premaxillary resection.
