RESUMO

Purpose: to describe and to compare, by means of perceptual speech analysis and videofluoroscopic assessment of tongue positions during the emissions of syllables /pa/ and /sa/ in subjects with and without cleft palate. Material and Method: A retrospective study of 100 subjects presenting with cleft lip and palate operated with velopharyngeal dysfunction was carried out, 52 males and 48 females (X=15,6 years SD=±10 years of age), and 21 noncleft individuals, being 18 females and 3 males (X=20 years SD=±6,3 years of age). Phonetic description of the emission of phonemes /p/ and /s/ isolated, in syllables, in words and phrases was utilized by means of perceptive-auditive evaluation, and videofluoroscopy in the lateral view during rest and emission of /papapa/ and /sasasa/. From a vertical imaginary line (Z), which separated the space between the tongue and the posterior pharyngeal wall, five different tongue positions were established. The presence of palatal fistula and the relation between the dental arches were analysed as well. Results and Conclusions: The cleft individuals presented greater posterior tongue displacement than their counterparts in the syllable /pa/ (P<0,0001). In the /sa/ syllable, only the cleft individuals presented tongue displacement. The glottal stop emissions and nasal air emission/weak pressure/facial grimacing in the /pa/ and /sa/ syllables presented posterior tongue displacement. The comparison between the perceptive-auditive evaluation and tongue position on the videofluoroscopy showed that experienced professionals may present difficulty in identifying certain types of compensatory articulation errors. The presence of palatal fistula and dental oclusion alterations in cleft individuals, did not cause posterior tongue displacement in the /pa/ and /sa/ syllables.
