Abstract (Summary)

In this study, children with isolated sagittal synostosis were examined relating to pre-speech acoustic features during prä- and postoperative moments. In addition these infants were compared to infants with positional plagiocephaly and healthy infants as a reference group.

The examinations took part within an interdisciplinary project "threedimensional sterephotogrammetric diagnosis of the infant head and evaluation of the therapy of infants with craniofacial asymmetries" at the University Hospital of Würzburg.

Many prior studies postulated, that craniofacial anomalies can lead to neurophysiological developmental disorders(Boltshauser et al. 2003, Chieffo et al. 2010, Korpilahti et al. 2012, Shipster et al. 2003, Virtanen et al. 1999).

Within this interdisciplinary project, preliminary examinations couldn´t find significant differences between children with positional plagiocephaly and children with isolated sagittal synostosis relating to acoustic features.

Up to now, there don´t exist researches concearning pre-speech development of infants with isolated sagittal synostosis during prä- and postoperative moments. Therefore in this dissertation comfort vokalizations of these infants were analyzed. As well articulatory skills as frequency-related and temporal parameters were examined.

Analyses of 2836 comfort vocalizations of 39 children were made based on existing routines at the „Zentrum für vorsprachliche Entwicklung und Entwicklungsstörungen“ (Center for Pre-speech Development and Developmental Disorders) of the University of Würzburg.

There were signficant differences relating to the length of segmented vokalizations at the postoperative date compared to präoperative within the SMO-group. At the same time the pause-index was decreased.

Also the fundamental frequency was significantly lower to the postoperative date within the SMO-group.

As long as there are no comparisons with infants with isolated sagittal synostosis without operative therapy, the results of this analyses will be taken as development-conditioned effects.

The present study indicates, that future studies are needed to evaluate the risk for children with craniofacial anomalies relating to neurophysological developmental disorders.
