[Hyperrhinophonia and craniofacial structure. A cephalometric analysis].

The aim of this study was to examine the relationship between the cephalometric measurements and the nasalance scores. Therefore the lateral cephalograms of 44 cleft palate patients were analysed and compared with the nasometric findings. The results revealed significant differences for the maxilla: the SNA angle and the inclination of the palatal plane were significantly related to the occurrence of hypernasality. Furthermore, the length of the soft palate and the ratio Spp-Ad3/Spp-V were found to be essential for the resonance of speech.
