Abstract
Purpose: The objective was to determine velopharyngeal (VP) status of stop consonants and vowels produced by young children with repaired cleft palate (CP) and typically developing (TD) children from 12 to 18 months of age. Method: Nasal ram pressure (NRP) was monitored in 9 children (5 boys, 4 girls) with repaired CP with or without cleft lip and 9 TD children (5 boys, 4 girls) at 12, 14, and 18 months of age. VP status was categorized as open or closed for oral stops and vowels in three contexts-consonant-vowel syllables, vowel-consonant-vowel syllables, and isolated vowels-on the basis of the presence or absence of positive nasal ram pressure. Results: At 12 months of age, TD children produced 98% of stops and vowels in syllables with VP closure throughout the entire segment compared with 81% of stops and vowels for children with CP (p < .0001). There were no significant group differences at 14 or 18 months of age. Conclusions: TD children exhibit consistent VP closure for stop consonants and vowels at 12 months of age. Some children with repaired CP do not achieve consistent closure until 14 months of age, approximately 3 to 4 months following palate repair.
