We developed a new method to analyze normal and abnormal movements of the hyoid muscular region as an indicator of hyoid bone motion during swallowing using ultrasound duplex-Doppler imaging. Hyoid bone motion can be monitored by studying the Doppler shift spectra and B-mode images produced by ultrasound duplex imaging of the hyoid region muscular attachments. We can accurately determine swallowing duration and trajectory of hyoid bone movement. This procedure can assist in discriminating between normal and abnormal movements of the hyoid bone and the surrounding muscles during swallowing. This method appears to be a highly consistent measure. We suggest that Doppler spectrum analysis can be used for defining hyoid position and displaying accurate movement, which may be useful in the diagnosis of swallowing disorders.
我们开发了一种新方法，通过超声双功多普勒成像分析舌骨肌肉区域的正常和异常运动，以此作为吞咽过程中舌骨运动的指标。通过研究舌骨区域肌肉附着处的超声双功成像产生的多普勒频移光谱和B超图像，可以监测舌骨运动。我们能够准确确定吞咽持续时间和舌骨运动轨迹。该程序有助于区分吞咽过程中舌骨及周围肌肉的正常和异常运动。这种方法似乎是一种高度一致的测量方法。我们建议多普勒频谱分析可用于确定舌骨位置并显示准确的运动，这可能对吞咽障碍的诊断有用。
