Comparison of multi-view videofluoroscopy and nasopharyngoscopy in the assessment of velopharyngeal insufficiency.

Ratings and drawings of multi-view videofluoroscopy and nasopharyngoscopic studies of the velopharyngeal valve in 25 subjects with velopharyngeal insufficiency (VPI) were compared. The videofluoroscopic projections assessed were lateral, base, and Towne views. The Towne view was visually compared with flexible fiber optic nasopharyngoscopic studies in the same subjects. The Towne view was found to compare well with nasopharyngoscopic examination, and lateral view alone was found to be inadequate for the description of velopharyngeal movements.
