| 内容記述 | Purpose: Videofluoroscopy is generally considered a "gold standard" technique; however t technique exposes subjects to radiation. Ultrasonography is applied widely in clinical practice because of low cost, safety of the technique, and absence of radiation exposure. The aim of this study was to evaluate hyoid bone movement trajectories during swallowing in healthy subjects using ultrasonography.Subject and Methods: Data were obtained from 15 healthy volunteers (mean age: 34.9± 9.3).The subjects were divided into 3 groups: 5 subjects in their 20s, 5 subjects in their 30s and 5 subjects in their 40s. The subjects were examined while sitting in an upright position, with the back against a wall to control movement. The transducer was placed in a longitudinal scan above the larynx. The hyoid bone was identified on the scan as a high echoic area with posterior acoustic shadow. Then, the subjects swallowed 5 mL of mineral water, with a measurement frequency of 5 times. The digital-ultrasonographic recordings were viewed at 30 frames/s for 3 seconds. Results: The movement was divided into 4 phases: A, slowly ascending phase; B, rapidly ascending phase; C, temporary pause phase (position of maximum rise); D, rapid and slow descending shifts toward the resting position phase. We easily visualized the hyoid bone trajectory using ultrasonography. In all cases, ultrasonographic analysis of the hyoid bone was confirmed to have a similar trajectory as determined with videofluoroscopy. Ultrasonography can accurately determine swallowing duration and trajectory of hyoid bone movement. There was a significant difference in swallowing duration between the 20s groups and 30s groups and between the 20s groups and 40s groups (P < 0.05). However, the difference between the 30s group and 40s group was not significant (P=0.87).Conclusion: The results show that the dynamic phase image of the hyoid bone movement can be revealed by ultrasonographic visualization. © 2009 Springer Berlin Heidelberg. | |||||
