Abstract:
Speech in 83 children (in total) with sub-mucous cleft palate was evaluated at the age of 6 years. Velopharyngeal insufficiency was graded on the basis of perceptual assessment, taking into account the co-existence of various velopharyngeal insufficiency characteristics in speech. Out of 56 patients operated with a velopharyngeal flap to eliminate velo-pharyngeal insufficiency, 42 of them (75%) achieved normal velopharyngeal function in speech. Dento-alveolar misarticulations were found in 35% of the children. Misar-ticulations occurred independently of velopharyngeal insufficiency.
