ABSTRACT

OBJECTIVE: The purpose of the study was to study the speech outcome in a series of 5-year-old children born with an isolated cleft palate and compare the speech with that of noncleft children and to study the impact of cleft extent and additional malformation on the speech outcome. DESIGN: A cross-sectional retrospective study. SETTING: A university hospital serving a population of 1.5 million inhabitants. SUBJECTS: Fifty-one patients with an isolated cleft palate; 22 of these had additional malformations. Thirteen noncleft children served as a reference group. INTERVENTIONS: A primary soft palate repair at a mean of 8 months of age and a hard palate closure at a mean age of 4 years and 2 months if the cleft extended into the hard palate. MAIN OUTCOME MEASURES: Perceptual judgment of seven speech variables assessed on a five-point scale by three experienced speech pathologists. RESULTS: The cleft palate group had significantly higher frequency of speech symptoms related to velopharyngeal function than the reference group. There were, however, no significant differences in speech outcome between the subgroup with a nonsyndromic cleft and the reference group. Cleft extent had a significant impact on the variable retracted oral articulation while the presence of additional malformations had a significant impact on several variables related to velopharyngeal function and articulation errors. CONCLUSION: Children with a cleft in the soft palate only, with no additional malformations, had satisfactory speech, while children with a cleft palate accompanied by additional malformations or as a part of a syndrome should be considered to be at risk for speech problems.

ABSTRACT

OBJECTIVES: The aim was to study the relationship between perceptual evaluation of speech variables related to velopharyngeal function and the pattern of nasal airflow during the velopharyngeal closing phase in speech in children with and without cleft palate. PARTICIPANTS: Fourteen children with cleft lip and palate or cleft palate only and 15 controls aged 7 and 10 years. All were native Swedish speakers. METHOD: Three experienced listeners performed a blinded perceptual speech evaluation. Nasal airflow was transduced with a pneumotachograph attached to a nasal mask. The duration from peak to 5% nasal airflow, maximum flow declination rate, and nasal airflow at selected points in time during the transition from nasal to stop consonants in bilabial and velar articulatory positions in sentences were estimated. The analysis was focused on the perceptual ratings of "velopharyngeal function" and "hypernasality." RESULTS: A strong association was found between ratings of "velopharyngeal function" and "hypernasality" and the pattern of nasal airflow during the bilabial nasal-to-stop combination /mp/. Both the sensitivity and specificity were 1.00 for the bilabial temporal airflow measure in relation to ratings of "velopharyngeal function." The nasal airflow rate during /p/ in /mp/ had a sensitivity of 1.00 and specificity of 0.92 to 0.96 in relation to ratings of "hypernasality." CONCLUSION: Assessment of the nasal airflow dynamics during the velopharyngeal closing phase in speech presents quantitative, objective data that appear to distinguish between perceptually normal and deviant velopharyngeal function with high sensitivity and specificity.
