为探讨舌骨与舌后表面在多颌畸形和小颌畸形中的关系，我们对16例安氏Ⅱ类和51例安氏Ⅲ类患者的舌对上气道腔的影响进行了研究，并对舌骨的位置、舌后表面的深度、从舌骨到咽后壁。我们能够评估在安氏III类中舌后表面和舌骨位置之间的显著相关性。然而，我们没有发现他们之间的联系在角度的II类。这可能是颏舌肌对舌骨定位的一种适应性特征，以起到补偿作用，防止小颌症呼吸暂停风险中的呼吸障碍。
In order to study relationship of the hyoid bone and posterior surface of the tongue in prognathism and micrognathia, we focused on the effect of the tongue on the upper airway lumen in 16 patients with Angle's Class II and 51 patients with Angle's Class III, and assessed the position of the hyoid, the depth from the posterior surface of the tongue, from the bottom of the vallecula and from hyoid bone to the posterior pharyngeal wall using lateral cephalograms. We were able to assess significant correlations between the posterior surface of the tongue and hyoid position in Angle's Class III. However, we found no association between them in Angle's Class II. This could be an adaptive feature of the genioglossus in response to hyoid localization to serve a compensatory role to prevent respiratory impairment in micrognathia at risk of apnoea.
