Articulation development in children with cleft lip/palate.

This longitudinal study analyzed the articulation development of 108 children with cleft lip/palate from three through eight years of age. The data suggest that as the severity of clefting increases the severity of the articulation deficit does also. Age and type of cleft were statistically significant factors in the development of normal articulation skills. Children with cleft lip appeared to be a homogeneous speaking group characterized by normal articulation development. However, children with palatal clefts remained at a heterogeneous group with regard to their articulation test performance through eight years of age. Future comparisons of articulatory proficient and articulatory deficient cleft palate children may shed light in morphological and other reasons for the articulation deficiency in some children.
