Purpose: To determine if children with repaired cleft palate and normal velopharyngeal (VP) closure as determined by aerodynamic testing exhibit greater acoustic nasalance than control children without cleft palate. Method: Pressure-flow procedures were used to identify 2 groups of children based on VP closure during the production of /p/ in the word hamper: (a) children with repaired cleft palate and normal VP closure (n = 23) and (b) controls without cleft palate and with normal VP closure (n = 16). Acoustic nasalance scores were obtained for all children during the production of syllables with high-pressure consonants and sentences with low-pressure consonants (i.e., low-pressure sentences). Results: Nasalance scores were generally higher for children with repaired cleft palate and normal VP function as compared to controls; however, a significant difference occurred only for low-pressure sentences ( p = .005). Conclusion: Results partially support a pressure-sensitive theory of VP function in that some children with repaired cleft palate may achieve VP closure during the production of high-pressure consonants but fail to do so during the production of vowels and low-pressure consonants. Clinical implications are discussed. [ABSTRACT FROM AUTHOR]

The purpose of the current research was to compare the lexical–grammatical skills of two-year-old children with and without repaired cleft palate (CP), accounting for the effect of variables such as vocabulary size at 18 months of age, maternal education level, and gender. Participants included 52 children with CP and 25 typically developing (TD) children. The CDI-WS was employed to measure vocabulary and grammatical skills. Significant differences were observed between the CP and TD groups with respect to the number of words, word forms (irregular nouns and verbs), word endings (overuse of plural (-s) and past tense (-ed) markers), the mean number of morphemes in their three longest utterances (M3L), and sentence complexity. In addition, compared to TD children, significantly smaller proportions of children with CP were observed to use words to talk about past and future events or use words to talk about an absent object. The difference between the CP and TD groups in terms of the size of vocabulary at 24 months of age remained statistically significant in the multivariable model. Among all predictors, the size of vocabulary at 18 months of age was identified as the most robust precursor of lexical and grammatical skills at 24 months of age. Gender was identified as a predictor of the M3L measure as an index for syntactic ability. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
