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...

BACKGROUND Secondary tumours of the hyoid bone and thyroid cartilage are extremely rare. In this paper, we present a case of the hyoid bone and thyroid cartilage metastases in a patient treated for sigmoid colon adenocarcinoma. CASE REPORT Four years after sigmoid colon adenocarcinoma was diagnosed and treated with surgery and chemotherapy, the patient developed bone metastases in the left sa...

We report the first case of dislocation of the symphysis between the great cornu and the body of the hyoid bone following strangulation in survivors. The present paper presents a rare case of injury to the hyoid bone and reviews the current knowledge on hyoid bone injuries in survivors.

conclusions pharyngeal airway dimensions, soft palate length, thickness, and position, and hyoid position are not significantly different between skeletal class i and class ii prepubertal children. results no significant difference in the upper airway, soft palate, and hyoid variables was found between the two groups (p > 0.05) and no correlation was found between anb difference and the other v...

the osteology of the hyoid and branchial arches in several representatives of eurypterygian fishes were examined. the hyoid arches consist of a single basihyal and urohyal, and the arch on each side consists of a dorsal and a ventral hypohyal, an anterior and posterior ceratohyal, an interhyal, and branchiostegal rays that are borne on the ceratohyals. the branchial arches consist of three sing...

OBJECTIVE (1) To test the hypothesis that there are no developmental changes in the pharyngeal airway depth and hyoid bone position from childhood to adulthood in normal Taiwanese persons, (2) to identify any sexual dimorphism, and (3) to find the predictive value of selective variables for the hyoid bone position. MATERIALS AND METHODS Lateral cephalometric radiographs of 239 normal Taiwanes...

OBJECTIVE To investigate the usefulness of ultrasonographic measurement of hyoid bone movement during swallowing. METHODS Fifty-two patients who had swallowing dysfunction were enrolled in this study. When a patient swallowed 5 mL of water while maintaining an upright sitting position, hyoid bone movement during swallowing was measured with ultrasonography. Recorded images were analyzed to me...

BACKGROUND CONTEXT The hyoid bone is used as a landmark in anterior upper cervical spine operations and is supposed to represent the level of C3 body. However, this correspondence between hyoid bone position and cervical level is not static and changes during surgery (extension after anesthesia). PURPOSE To find the cervical level corresponding to the position of hyoid bone before and after a...

The human hyoid bone supports the base of the tongue and is involved in breathing, chewing, and swallowing as well as in the muscle movements associated with articulation. Accordingly it plays an important bone for a human to live. It is a very interesting organ also in multiple special area, including anatomy, mastication, swallowing, articulation, and also forensic medicine. In the morphologi...

BACKGROUND AND PURPOSE ORN is a postradiation complication that has been well-documented in the medical literature. Most cases in the head and neck have been described in the mandible or larynx. Only a handful of cases in the hyoid bone are documented, all in the clinical literature. Our purpose is to present the clinical and imaging features of ORN involving the hyoid bone. MATERIALS AND MET...
