Prenatal Imaging for Cleft Lip and Palate.

Cleft lip (CL) and cleft palate (CP) are common orbitofacial birth defects that vary in severity and effect on anatomical function. They might occur as an isolated event, be associated with a syndrome, or result from genetic and environmental factors. Diagnosis and treatment of individuals begin prenatally and can extend through adulthood. Sonography and magnetic resonance imaging are used prenatally to evaluate and monitor treatment outcomes and complications associated with CL and CP. This article discusses the anatomical development of CL and CP and the imaging techniques used to diagnose and manage them.
