OBJECTIVE Using the Hörmann technique of hyoid suspension in sleep apnea surgery, a steel wire is placed through the thyroid cartilage and slung around the hyoid bone. However, we experienced thyroid cartilage fracture by steel wire traction. A modification is presented to avoid thyroid cartilage fracture. STUDY DESIGN Case series with chart review. SETTING University hospital. SUBJECTS A...

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...

The aim of this study was to verify if hyoid myotomy without hyoid suspension is effective in surgical treatment of obstructive sleep apnoea syndrome (OSAS). We recruited six patients with OSAS, aged between 34 to 60 years, with retropalatal and retrolingual upper airway obstruction, non-obese (BMI < 27) and non-compliant to continuous positive airway pressure therapy. Pre-surgical clinical and...

The use of a transhyoid pharyngotomy approach resulted in a lower morbidity rate in the surgical repair of cleft palatal defects when compared with the use of a mandibular symphysiotomy approach. Successful healing was achieved completely in four horses, partially in three horses, and not at all in one horse following one or more surgical repairs.

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 ...

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.

Gegenbaur's classical hypothesis of jaw-gill arch serial homology is widely cited, but remains unsupported by either palaeontological evidence (for example, a series of fossils reflecting the stepwise transformation of a gill arch into a jaw) or developmental genetic data (for example, shared molecular mechanisms underlying segment identity in the mandibular, hyoid and gill arch endoskeletons)....

Purpose This study was aimed to examine the effectiveness of a high-speed jaw-opening exercise, which targets the contraction of fast-twitch muscle fibers, in improving swallowing function. Subjects and methods Twenty-one subjects (mean age 74.0±5.7 years) with dysphagia-related symptoms, such as coughing or choking during eating, performed the exercise. None of the included subjects had neur...

UNLABELLED Woodpeckers avoid brain injury while they peck at trees up to 20Hz with speeds up to 7m/s, undergoing decelerations up to 1200g. Along with the head, beak and neck, the hyoid apparatus (tongue bone and associated soft tissues) is subjected to these high impact forces. The shape of the hyoid apparatus is unusual in woodpeckers and its structure and mechanical properties have not been ...

Hyoid bone fracture is usually due to strangulation, and, rarely, other forms of trauma. Its sequaelae are often immediate and distressing, and may be fatal. A prominent diagnostic sign is a palpable click. Concealed fractures can present confusing symptoms. Two cases of previously undiagnosed hyoid bone fracture are presented, one affecting the greater cornu, the other, a fragmented fracture o...
