OBJECTIVE The purpose of this study was to characterize the swallowing sound and identify the process of sound generation during swallowing in young healthy adults. METHODS Thirty-three healthy volunteers were enrolled and allocated into three experimental groups. In experiment 1, a microphone was attached to one of eight cervical sites in 20 subjects, participants swallowed 5 ml water, and t...
Detailed morphological analyses have identified a number of different mechanical pathways by which the morphologically complex cranial system of fishes can achieve mouth opening and hyoid depression. However, many of these proposed mechanisms remain untested. Furthermore, very little is known about the precise timing of activity of each of these mechanisms, and about the magnitude of each mecha...
Caudal tracheal displacement (TD) leads to improvements in upper airway (UA) function and decreased collapsibility. To better understand the mechanisms underlying these changes, we examined effects of TD on peripharyngeal tissue stress distributions [i.e., extraluminal tissue pressure (ETP)], deformation of its topographical surface (UA lumen geometry), and hyoid bone position. We studied 13 su...
Introduction: This study aims to evaluate the parameters that might have an impact on swallowing performance after a total glossectomy with laryngeal preservation (TGLP). Methods: Among 39 patients who underwent surgery with curative intent for squamous cell carcinoma of the tongue, our retrospective analysis focused on 18 patients treated by TGLP and flap reconstruction. The flap was position...
Motion analysis of the hyoid bone via videofluoroscopic study has been used in clinical research, but the classical manual tracking method is generally labor intensive and time consuming. Although some automatic tracking methods have been developed, masked points could not be tracked and smoothing and segmentation, which are necessary for functional motion analysis prior to registration, were n...

A 39 years old man sustained a fracture of the hyoid bone following closed neck injury while weight-lifting in the gym. Though commonly occurring in association of other neck fractures of the laryngeal skeleton, the fracture was isolated. Isolated hyoid bone fractures resulting from trauma other than strangulation are very rare, and occur more frequently in young men more than in women. These f...
