Prenatal 3D sonography of an isolated lateral facial cleft

Lateral facial cleft is a rare congenital anomaly, but all affected infants require surgery under general anesthesia. Conventional 2‐dimensional coronal view of the face, which is typically used for identification of facial clefts, has limitations with regard to detection of this anomaly. We describe a case of prenatal diagnosis of isolated lateral facial cleft made with 3D sonography and highlight the importance of this tool in the diagnosis of this rare facial deformity.
