A combined speech and cephalometric analysis was performed on 60 patients with class III malocclusion to evaluate the interaction between the cranio-facial skeleton and the disorder of an open nasal speech. There was an increase of durable open nasal speech after tonsillectomy but not after adenoidectomy. This predisposition to open nasal speech in class III patients appeared to be increased by the formation of the surrounding bony structures. In dependency to the cranio-facial morphology in the vertical dimension, the configuration of the bony nasopharynx and the sagittal jaw relationship were of significant importance. The cephalometric measurements confirmed the results of the speech analysis that the position and function of the soft palate are of essential significance for the development of an open nasal speech.
对60例III类错牙合患者进行了语音和头影测量分析，以评估颅面骨骼与开放性鼻音障碍之间的相互作用。扁桃体切除术后持续性开放性鼻音增加，但腺样体切除术后未增加。III类患者开放性鼻音的这种易感性似乎因周围骨结构的形成而增加。根据垂直维度的颅面形态，骨性鼻咽的形态和矢状颌关系具有重要意义。头影测量结果证实了语音分析的结果，即软腭的位置和功能对开放性鼻音的发生至关重要。
