The Septum and Nasomaxillary Vault Associated with Unrepaired Unilateral Cleft Lip and Palate: A Data-Driven 3-Dimensional Model

This 3-dimensional, data-driven model contradicts prior models and confirms a collapsing twist of the cleft-side aperture and medialization of the bony margin of the nasal airway with deviation of the nasal bone complex toward the noncleft side. This analysis defines the critical anatomical characteristics of the cleft nasal deformity and informs the goals of nasal correction at the time of primary repair.
