OBJECTIVE To investigate effects of tracheostomy tube on the movement of the hyoid bone and larynx during swallowing by quantitative analysis of videofluoroscopic swallowing study. METHOD 19 adult stroke patients with tracheostomies, who met the criteria of decannulation participated. Serial videofluroscopic swallowing studies were done over 14 days before decannulation, within 24 hours befor...

Hyoid fractures in athletes are rare injuries that can be difficult to diagnose. Typically resulting from a direct blow to the anterior neck, hyoid fractures can lead to subcutaneous edema and subsequent airway compromise. The treatment of this fracture depends largely on the severity of the presenting symptoms. Generally, these fractures do not require surgical intervention but warrant close o...

Introduction: In our study, we aimed 200 cases were evaluated for the length, width and angle of hyoid bone and its distance from certain anatomical structures. Methods: This study was perfomed retrospectively in 2010 - 2013 on 200 CT images. 3D volume rendering images of pure hyoid bone were created from the axial CT images in 1 mm slice thickness. In our study, 200 cases (94 female, 106 male...

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...

The nurse shark, Ginglymostoma cirratum, is an obligate suction feeder that preys on benthic invertebrates and fish. Its cranial morphology exhibits a suite of structural and functional modifications that facilitate this mode of prey capture. During suction-feeding, subambient pressure is generated by the ventral expansion of the hyoid apparatus and the floor of its buccopharyngeal cavity. As i...

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...

In the conventional supracricoid laryngectomy technique, tumors extending beyond the lingual surface of the epiglottis with tongue base invasion are contraindicated due to the requirement of the hyoid bone resection. The loss of the hyoid bone causes intractable aspiration and renders the cricoidal pexy process impossible. Therefore, surgeons tend to treat such tumors with total or subtotal lar...

OBJECTIVE To assess the position and movements of the hyoid bone during deglutition in patients with open bite. METHODS Thirty-six subjects were divided into 2 groups according to the presence of anterior open bite. The open bite group (OBG) and control group each comprised 18 patients with a mean overbite of -4.9 ± 1.9 mm and 1.9 ± 0.7 mm. The position of the hyoid bone during the 4 stages o...

Fish typically use a rostro-caudal wave of head expansion to generate suction, which is assumed to cause a uni-directional, anterior-to-posterior flow of water in the expanding head. However, compared with typical fish, syngnathid fishes have a remarkably different morphology (elongated snout, small hyoid, immobile pectoral girdle) and feeding strategy (pivot feeding: bringing the small mouth r...

BACKGROUND AND PURPOSE Carotid artery dissection (CAD) is more common with increased styloid process length. Our goal was to determine whether proximity of the styloid process and the hyoid bone to the internal carotid artery (ICA) was a risk factor for CAD. METHODS We studied axial slices on computed tomography angiograms of 88 patients with nonaneurysmal CAD, from 88 age- and sex-matched co...
