The aim of this study was to investigate temporal ultrasound measurements of the hyoid bone displacement during swallowing following thyroidectomy in women and to relate these measures to age, clinical outcomes, and upper digestive airway symptoms. The sample was divided into an experimental group (EG) of 20 women who underwent thyroidectomy (mean age = 49.55 years ± 15.14) and a control group (CG) of 20 healthy women volunteers (mean age = 40.75 years ± 15.92). Both groups were submitted to ultrasound assessment to obtain four temporal measurements of hyoid bone displacement during swallowing: elevation, anteriorization, maximum displacement, and maintenance of maximum displacement. In both groups, swallowing of ten milliliters of liquid and the same volume of thickened liquid (honey) were analyzed. The images were recorded on video (30 frames/second) and analyzed according to a standardized protocol. Temporal measurements of hyoid bone elevation and maximum displacement during swallowing of thickened liquid were significantly shorter in EG (p = 0.034 and p = 0.020, respectively). There were no differences in the swallowing of liquid, and no other variable was related to the ultrasound temporal measurements investigated. This study concludes that women who undergo thyroidectomy have a shorter time of hyoid bone elevation and maximum displacement during swallowing of 10 mL of thickened liquid.
本研究旨在探讨女性甲状腺切除术后吞咽时舌骨位移的时间超声测量，并将这些测量结果与年龄、临床结果和上消化道气道症状相关联。样本分为实验组（EG）和对照组（CG）。实验组（EG）为 20 名接受甲状腺切除术的女性（平均年龄 49.55 岁±15.14 岁），对照组（CG）为 20 名健康的女性志愿者（平均年龄 40.75 岁±15.92 岁）。两组均进行超声评估，以获得吞咽时舌骨位移的四个时间测量值：抬高、前位、最大位移和最大位移维持。两组均分析吞咽 10 毫升液体和相同体积的增稠液体（蜂蜜）。图像以视频（30 帧/秒）记录，并根据标准化方案进行分析。在吞咽增稠液体时，EG 组的舌骨抬高和最大位移的时间测量值明显缩短（p=0.034 和 p=0.020）。吞咽液体时没有差异，也没有其他变量与研究中的超声时间测量值相关。本研究得出结论，接受甲状腺切除术的女性在吞咽 10 毫升增稠液体时，舌骨抬高和最大位移的时间更短。
