Three-dimensional prenatal diagnosis of frontonasal malformation and unilateral cleft lip/palate.

ABSTRACT

Frontonasal malformation includes a spectrum of anomalies involving the eyes, nose, lips, forehead and brain. We present a case in which a fetal labial cleft was initially identified using traditional two-dimensional sonography. Three-dimensional sonography with multiplanar reconstruction and surface-rendering were essential to establish the diagnosis of frontonasal malformation with severe nasal hypoplasia and unilateral complete cleft lip/palate.
