Lateral videofluoroscopy: a modification to aid in velopharyngeal assessment and measurement.

To overcome the difficulty of obtaining adequate videofluoroscopic images with small children because of lack of cooperation and their inability to keep their heads still and correctly rotated, a 3D View-Master was attached to the x-ray table. Its use greatly increased the ability to conduct lateral videofluoroscopies of small children by improving patient compliance, stabilizing rotation and reducing unwanted head movement, and by standardizing magnification.
