OBJECTIVE To compare tongue thickness, the shortest hyoid-thyroid approximation (distance between the hyoid bone and thyroid cartilage), and the time interval between the initiation of tongue movement and the time of the shortest hyoid-thyroid approximation, by using ultrasonography in healthy controls and patients with Parkinson disease (PD). METHODS Healthy controls and PD patients with dys...

Mandibular advancement (MA) increases upper airway (UA) patency and decreases collapsibility. Furthermore, MA displaces the hyoid bone in a cranial-anterior direction, which may contribute to MA-associated UA improvements via redistribution of peripharyngeal tissue stresses (extraluminal tissue pressure, ETP). In the present study, we examined effects of MA on ETP distributions, deformation of ...

The embryological origin of the hyoid bone is a point of uncertainty, with controversy surrounding the relative contribution of the second pharyngeal arch to hyoid development. We encountered a 52-year-old male with bilateral bony styloid extension to the lesser cornu of the hyoid bone during the workup of a patient with laryngeal cancer. This embryological malformation clearly supports the hyp...

INTRODUCTION We hypothesized that the size of the hyoid bone itself may affect the severity of sleep apnea. The aim of this study was to identify the relationship between hyoid bone dimensions and the severity of sleep apnea using computerized tomography (CT) axial images. METHODS We retrospectively measured the hyoid bone in axial images of neck CTs and correlated these measurements with res...

Musculoskeletal injuries are exceedingly common in American football because of the contact-and-collision nature of the sport. More than 350,000 injuries are documented in the >1 million high school athletes participating in American football annually. Injuries to the neck are largely uncommon, composing only *6% of the injury total; however, if they are not properly diagnosed and treated, they...

INTRODUCTION We describe here the first reported case of a follicular adenoma arising from a thyroglossal duct remnant within the hyoid bone in Singapore. CLINICAL PICTURE A 32-year-old woman presented with an asymptomatic lump in the anterior midline of her neck of three months' duration. CT scan showed an expansile lesion localised to the medulla of the body of the hyoid. TREATMENT A well...

This paper reports on apparently the first case of a pharyngeal osteoma that developed from the hyoid bone. An 84-year-old man's, presenting symptom was a slight throat pain. Endoscopic examination revealed a huge mass occluding the pharyngeal space. CT scan of the neck showed a large osseous mass adjacent to the hyoid bone. Transoral resection with tracheostomy was performed. Histopathological...

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...
