Dissertation/Thesis Abstract

Untersuchung der laryngealen Regelleistung in Form der Kurzzeitvariabilität der Grundfrequenz in vorsprachlichen Vokalisationen des 2. und 3. Lebensmonats von Säuglingen mit und ohne oro-faziale Spaltbildungen

Abstract (Summary)

The present paper analyses spontaneous cries during the second and third month of life of 19 infants with cleft lip and palate compared to 24 non-cleft infants as a reference group. Research has been performed in the light of the influence of pre-orthodontic treatment for the first time. Tests have been focused on fundamental frequency (F0), length of the infant cries and on different parameters of the F0 stability (Jitter, Shimmer, PPQ). No significant varieties have been found between infants with cleft lip and palate and the non-cleft contemporaries. A decisive impact of the intra-oral plate on fundamental frequency of pre-linguistic vocalization has not been found either. Almost all tests have shown a positive effect of the pre-orthodontic treatment on voice stability. This strongly suggests that the orthodontic measure has a favourable impact on the stability of Phonation. The current tests show significant differences in particular between the non-cleft group and the group with unilateral cleft lip and palate. Whether these findings will be confirmed or not has to be shown by future research that is preferably focused on appropriate paediatric audiology investigations / examinations.
