No significant differences in dimensions of the hard palate or SDB were found between the groups but the snore index tended to be higher in the study group (<jats:italic>p<\/jats:italic>\u2009=\u20090.051).

No significant difference regarding dimensions of the hard palate or SDB between the groups was found nor between SDB and maxillary dimensions.
