Special swallowing problems in children.

As the swallowing process evolves from infantile suckle feeding through transitional feeding to mature function, the process can go awry at many points. Understanding the changes in structure and function of the mouth and pharynx that occur with growth and development is of basic importance. When a child is referred because of unsuccessful feeding or suspicion of aspiration, dynamic imaging of the swallowing mechanism and scrutiny of radiographic abnormalities described in this article can lead to greater understanding of the underlying cause and to more effective treatment.
