This video-recorded study is sometimes done to evaluate the safety and effectiveness of your child’s swallow. A physician gently places a small, thin flexible endoscope with a camera down through the nose to view the back of the throat.

While the study is being recorded, a speech language pathologist carefully feeds the child small amounts of certain liquids or foods that have green food coloring added (so that it is easy to see on the video monitor as the child swallows). This study is sometimes used instead of a modified barium swallow study, which must be done in Radiology.
