It is generally recognized that early successful palatal repairs result in increase of the number of cleft palate (CP) children who develop normal articulation without any training intervention. However, several studies indicated that, even in CP children repaired successfully in early times, 40 to 50% showed abnormal articulation which was different from so-called cleft palate speech. The aim of this study was to compare the postsurgical articulation found in CP children who acquired velopharyngeal closure (VPC) at age one (Group A) with that in CP patients who acquired VPC at later than age 10 (Group B) . The subjects were 187 postsurgical CP patients whose VPC was evaluated competent: 134 for Group A and 53 for Group B. Percentage of abnormal articulation in Group A (45%) was significantly smaller than that in Group B (79%, p<05) . Concerning the error types, palatalized articulation in Group A (73%) and glottal stops in Group B (90%) overwhelmed other error types in each group. The results suggested that research on the cause of palatalized articulation from morphological and functional points of view was necessary in order to decrease the incidence of abnormal articulation in early and successfully repaired CP children.
