Phonology in Swedish-speaking 5-year-olds born with unilateral cleft lip and palate and the relationship with consonant production at 3 years of age.

PURPOSE: At approximately 3 years of age approximately 50% of the children born with cleft palate present with phonological/articulatory difficulties. Differences between children with and without cleft palate have been reported to decline with age; however, the phonology in children with cleft palate at pre-school age/early school age has rarely been explored. The purpose of this study was to assess phonology in children with unilateral cleft lip and palate (UCLP) at age 5 and its relationship with performances at 3 years of age. METHOD: The study included 29 children with UCLP and 20 without UCLP. Percentage correct consonants adjusted for age (PCC-A) and number of consistent phonological simplification processes were assessed from phonetic transcriptions. In addition, a descriptive analysis of phonological/articulatory processes was performed. RESULT: The children with UCLP displayed significantly lower PCC-A and more phonological processes at age 5 years than peers without UCLP. The correlations between the outcomes at 3 and 5 years of age were significant. CONCLUSION: Still at 5 years of age many children with cleft palate have phonological problems and it is possible to identify children at risk for impaired phonology at earlier age.
