Samenvatting

AIMS:
The purpose of this study was to describe articulation and resonance characteristics of Ugandan English-speaking children with cleft lip and palate (CLP) after synchronous lip and palatal closure (Sommerlad technique) prior to the age of 6 months in comparison with an age- and gender-matched control group.
METHODS:
Eleven Ugandan patients with CLP (mean age 4;9 years), repaired during a synchronous lip and (soft and hard) palatal closure at a mean age of 3.4 months, were included as well as a control group (n = 22) consisting of 2 Ugandan age- and gender-matched noncleft children for each patient (mean age 4;10 years). Objective and perceptual speech assessment techniques were applied.
RESULTS:
Consonant inventories were significantly smaller in the CLP group. Moreover, phonetic disorders and phonological processes occurred in 91 and 100% of the CLP group, respectively. Perceptual consensus evaluation revealed absence of hyponasality and cul-de-sac resonance in all patients. Hypernasality and nasal emission/turbulence occurred in 18 and 27% of the patients, respectively. No significant group differences were observed regarding the mean nasalance values of oral speech samples.
CONCLUSION:
Various deviations from normal speech development seem to occur in patients with CLP following synchronous lip and palatal closure before 6 months of age.
