Novel approach to distinguish submucous cleft palate from isolated cleft palate by prenatal ultrasound visualization of fetal swallowing

Videoclip S1. The intact soft palate when the fetus is swallowing can be observed on grayscale ultrasound. Videoclip S2. Isolated cleft palate - amniotic fluid is passing through the soft palate defect. Videoclip S3. Submucous cleft palate - the intact mucous membrane prevents the passage of amniotic fluid through the hard palate defect.
