This study compares 30 cleft lip and palate (CLP), 55 cleft palate (CP) and 28 cleft lip (CL) children in terms of descriptive speech data, nasalance data and the frequency of secondary surgery performed on patients. The CLP children had less hypernasality and audible nasal air emissions than CP children. The groups were equal with respect to articulation proficiency. The CLP and CL children generated similar nasalance scores, which were significantly lower than those of the CP children. Secondary surgery was equally common in the CLP and CP children.
