Mat erial and Methods: because of its anatomical and functional relationship with the craniofacial complex, we assessed the cephalometry of the hyoid bone position in relation to the respiratory pattern of these 53 female children, with average age of 10 years; 28 of them are nasal breathers and 25 are oral breathers. Horizontal, vertical and angular cephalometric measures were used in order to...

In 1981 Bibby and Preston commented on the uniqueness of the anatomic relationships of the hyoid bone, notably that it was not fixed in space by bony articulations. This fact alone makes it a potential indicator of certain individual features of importance in orthodontic diagnosis and treatment. This study investigates the effect of mouth breathing and tongue-thrusting on the hyoid bone positio...

PURPOSE This study aimed to examine the relationship between jaw opening force and hyoid bone dynamics and resting position in elderly individuals based on gender. SUBJECTS AND METHODS Subjects were 36 healthy elderly individuals aged ≥65 years without dysphagia (16 men and 20 women; mean age 75.5 years, range 65-88 years). Videofluorographic images during the swallowing of 10 mL of 40% (w/v)...

OBJECTIVES/HYPOTHESIS Aspiration, the passage of a bolus below the vocal folds, increases morbidity and mortality in the elderly by increasing the risk of aspiration pneumonia and other conditions. We hypothesized that altered position of the hyoid bone associated with aging may negatively affect airway protection during swallowing (i.e., aspiration) in older adults. STUDY DESIGN Retrospectiv...

INTRODUCTION Thyroglosal duct cyst is a common anomaly with an incidence of 7% in adults, the rate of carcinoma in TGDC is 0.7-1.6%, and are extremely rare those originated in the hyoid bone. PRESENTATION OF CASE A 60 years old male patient, had a hard mass in the anterior neck. CT revealed a hyoid tumor. Hyoid bone resection was performed, the pathological report show a conventional papillar...

Fractures of the hyoid bone are very rare. Diagnosis of hyoid fracture is difficult and can be made only with a strong degree of suspicion. We report a case of isolated hyoid bone fracture due to blunt trauma to the neck. A 26-year-old woman was admitted to emergency department for motor vehicle accident. She complained of dysphagia and anterior neck discomfort. Physical examination showed hype...

Chondrosarcoma of the hyoid bone is rare. Only 14 cases have been reported in the literature, to date. We present a case of chondrosarcoma of the hyoid bone with imaging, surgical, and pathologic correlation, and a review of the literature.

Pain that is worsened by swallowing and localised laterally between the thyroid cartilage and hyoid bone is termed thyrohyoid syndrome. Similar syndromes with other names (such as styloid syndrome) have been described based on the localisation of symptoms.1–3 It is likely that calcification or tendonitis of the hyoid bone and related muscles and ligaments are responsible for these symptoms. Mic...
