CLEFT TYPE AND SPEECH PROFICIENCY

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 pat ients. The CLP children had less hypernasality and audible nasal air e missions than CP children. The groups were equal with respect to artic ulation proficiency. The CLP and CL children generated similar nasalan ce scores, which were significantly lower than those of the CP childre n. Secondary surgery was equally common in the CLP and CP children.
