A comparative study of four methods of evaluating velopharyngeal adequacy.
Forty-eight subjects with repaired palatal clefts were divided into three major groups on the basis of speech symptoms and were examined for velopharyngeal valving integrity by means of the R-D nasal manometer, pressure-flow techniques, the Hunter oral manometer, and videofluoroscopy. Videofluoroscopy appeared to provide data that most nearly agreed with predictions of valving made from speech. The Hunter oral manometer was the least useful of the four techniques.
