Hyoid Bone Tracking in a Videofluoroscopic Swallowing Study Using a Deep-Learning-Based Segmentation Network

Abstract: Kinematic analysis of the hyoid bone in a videofluorosopic swallowing study (VFSS) is important for assessing dysphagia. However, calibrating the hyoid bone movement is time-consuming, and its reliability shows wide variation. Computer-assisted analysis has been studied to improve the efficiency and accuracy of hyoid bone identification and tracking, but its performance is limited. In this study, we aimed to design a robust network that can track hyoid bone movement automatically without human intervention. Us… Show more

“…They found excellent inter-rater reliability of hyoid bone detection between the algorithm and a group of three human annotators. Similarly, Kim et al [40] utilized automated hyoid bone tracking and designed a network that can detect salient objects in VFSS images. Zhang et al [41] also presented a model that could automatically detect the hyoid bone; however, inaccuracies in tracking were a limitation in this study.…”

“…The tongue plays a fundamental role in the nutritional supply process through the stages of swallowing. We can distinguish three phases in swallowing depending on the anatomical area where the bolus is present: oral, pharyngeal, and esophageal [45]. In the oral phase, the tongue with the bolus (solid or fluid) moves away from the soft palate bringing the apex toward the retroincisal-palatal spot, and it touches and presses against the hard palate and pushes the bolus posteriorly toward the pharynx (pharyngeal phase) to finally enter the bolus into the esophagus (esophageal phase); after this last phase, the tongue resumes contact with the soft palate [28,46].…”

“…The portions of the tongue that move the most (elevation) during these phases are the frontal, medial, and posterior areas; in particular, the posterior portion rises more [46]. During swallowing, the tongue (lower lingual portion) moves the hyoid bone in horizontal and vertical actions; in the pharyngeal phase, the hyoid is pushed forward and upward [45]. Lingual dysfunctions, attributable to advancing age (very frequent) or to the presence of disorders and pathologies, cause dysphagia which decreases the patient's optimal nutrition [47,48].…”
