Abstract:Objectives: Define the structure and function of the fetal pharynx and larynx. We describe for the first time the various components of these anatomical sites by 3D multiplanar and render modes during the late 1st and 2nd trimesters.

Transabdominal 3DUS scan of the fetal neck was acquired. The pharynx width and height, upper, middle, and lower lary… Show more
