目的：建立一种新的方法，通过整合超声（US）视频成像和头颅侧位片，对下颌无颌患者正颌手术前后吞咽舌运动进行定性和定量评价。材料和方法：对10例下颌无颌症患者进行正颌手术前后的超声影像和头颅侧位片检查，并与丙烯酸定位牙合板（POP）结合作为叠加的标记。在吞咽舌运动的各个阶段（1-5阶段），测量并比较舌背前后高度相对于腭高度的百分比。评价同一受试者重复5次吞咽舌运动的个体差异。结果：该量表的个体变异值较小，测量误差均为< 0.20 and the inter-examiner correlation coefficient values were all >0.80。术后测量的后舌背高度百分比在所有吞咽阶段（除第4阶段外）均显著大于术前测量的百分比。在七个出10个科目，舌尖区域突出的上切牙边缘手术前可以接触上切牙的舌面postoperatives.Conclusion：新开发的US-cephalogram集成方法是有用的定性和定量评价的吞咽舌运动在临床环境中没有额外的辐射暴露。
Purpose: To establish a novel method for qualitative and quantitative evaluation of deglutitive tongue movement by integration of ultrasound (US) video imaging and lateral cephalogram of mandibular prognathism subjects before and after orthognathic surgery.Materials and methods: The US video imaging and lateral cephalogram were obtained from ten mandibular prognathism subjects before and after orthognathic surgery and integrated with an acrylic positional occlusal plate (POP) as a marker for superimposition. The percentage of the anterior and posterior tongue dorsum height, with respect to the palatal height, was measured and compared at each stage (Stages 1–5) of the deglutitive tongue movement. Individual variation on 5-times repeated deglutitive tongue movement in the same subject was evaluated. Furthermore, the intra- and inter-examiner reliability was evaluated using Dahlberg’s formula and correlation coefficient.Results: The individual variation value was small enough, while the intra-examiner measurement errors were all < 0.20 and the inter-examiner correlation coefficient values were all > 0.80. The percentage of the posterior tongue dorsum height in the postoperative measurement was significantly larger than that measured preoperatively at all deglutitive stages, except Stage 4. In seven out of ten subjects, the tongue tip region protruded over the upper incisor edge before surgery could touch the lingual surface of the upper incisor postoperatively.Conclusion: The newly developed US-cephalogram integration method was useful for qualitative and quantitative evaluation of the deglutitive tongue movement in a clinical setting without additional radiation exposure.
