INTRODUCTION: The morphological variations of the thyroid gland have been reported from different parts of the world. The variations are due to remnant or non-specific development of the parts of the thyroid gland. Surgical operation of the thyroid gland has been the treatment of choice in various thyroid pathologies. Prior knowledge of the morphological variation is important to ensure better results from these surgical operations. AIM: To study the prevalence of morphological variations seen in the thyroid glands in the upper Assam region of Northeast India...

The head lift exercise (HLE) is a head-raising workout performed in a supine position. This exercise facilitates activation of the submental muscles located above the hyoid bone in front of the neck. HLE is a potential method to improve the movement of the hyolaryngeal movement and swallowing functions. The purpose of this study was to investigate the effect of HLE on the hyolaryngeal movement and aspiration in patients with dysphagic stroke. A total of 27 patients with stroke were randomly assigned either into the experimental (n=13) or the control group (n=14)...

BACKGROUND AND OBJECTIVES: Glossopharyngeal nerve (GPN) blocks are usually performed by topical, intraoral, or peristyloid approaches, which carry significant complication risks due to the proximity of important neurovascular structures. This study presents a proof of concept for a new ultrasound (US)-guided technique, which would block the GPN distally, in the parapharyngeal space, away from the immediate vicinity of high-risk collateral structures. METHODS: Five cadaver heads were dissected, and the location of the GPN was explored bilaterally...

Objective The videofluoroscopic swallow study (VFSS) is the gold standard diagnostic tool to evaluate oropharyngeal dysphagia. Although objective measurements on VFSS have been described, there is no universal method of analysis, and the majority of clinicians use subjective interpretation alone. The purpose of this investigation was to evaluate the accuracy of subjective VFSS analysis. Study Design Double-blinded experiment. Setting Tertiary care laryngology center. Subjects and Methods Seventy-six de-identified videos from VFSS evaluations of patients with dysphagia were presented to blinded, experienced speech-language pathologists and laryngologists individually...

Surface landmarks in the neck are important for orientations of cervical glands, arteries, veins, nerves and vertebrae. Recent research suggests some orientations are not correct. What are the cervical landmark orientations in the Chinese population? In this study, two essential cervical anatomy planes, the thyroid cartilage and C7 planes, were assessed in living adult Chinese subjects using computed tomography (CT), and the hyoid, carotid bifurcation, cricoid cartilage, thyroid arteries and vertebral artery were simultaneously positioned...

BACKGROUND: Chin-up posture is frequently used to manage oral dysphagia after head and neck cancer. This prospective study investigates the effects of chin-ups on the sequence of pharyngeal swallowing events. METHODS: Twelve healthy young adults performed 45 consecutive swallows of 5 mL water across 3 phases on videofluoroscopy: 5 swallows in the neutral head position; 30 swallows during chin-up posture; and 10 swallows in the neutral head position. Swallowing kinematic and bolus flow measures for 9 swallowing events were recorded...

The head is considered the major novelty of the vertebrates and directly linked to their evolutionary success. Its form and development as well as its function, for example in feeding, is of major interest for evolutionary biologists. In this study, we describe the skeletal development of the cranium and pectoral girdle in Siberian (Acipenser baerii) and Russian sturgeon (A. gueldenstaedtii), two species that are commonly farmed in aquaculture and increasingly important in developmental studies. This study comprises the development of the neuro-, viscero- and dermatocranium and the dermal and chondral components of the pectoral girdle, from first condensation of chondrocytes in prehatchlings to the early juvenile stage and reveals a clear pattern in formation...

An elongated styloid process (ESP) is present in 4% of the general population. It is sometimes found incidentally by panoramic radiography or computed tomography in the clinical setting. Few detailed morphometric studies of this phenomenon have been performed, however, especially regarding its histologic aspects. During anatomic dissection of a 71-year-old man who had died from cardiac failure and whose body had been donated to our department for medical student training, an ESP was found while disconnecting the stylohyoid muscle from the hyoid bone...

In dysphagia the ability of elevating the larynx and hyoid is usually impaired. Electromyography (EMG) and Bioimpedance (BI) measurements at the neck can be used to trigger functional electrical stimulation (FES) of swallowing related muscles. Nahrstaedt et al.(1) introduced an algorithm to trigger the stimulation in phase with the voluntary swallowing to improve the airway closure and elevation speed of the larynx and hyoid. However, due to non-swallow related movements like speaking, chewing or head turning, stimulations might be unintentionally triggered...

Diffuse Idiopathic Skeletal Hyperostosis (DISH) can cause ossification of ligaments and may affect the spine. We report a case of obstructive sleep apnea in a patient with significant upper airway narrowing secondary to cervical DISH. This patient had an initial apnea-hypopnea index (AHI) of 145 events/hour and was treated with uvulopalatopharyngoplasty, genial tubercle advancement, hyoid suspension, septoplasty, inferior turbinoplasties, and radiofrequency ablations to the tongue base which reduced his AHI to 40 events/hour...

BACKGROUND AND AIMS: Accurate prediction of the Cormack-Lehane (CL) grade preoperatively can help in better airway management of the patient during induction of anaesthesia. Our aim was to determine the utility of ultrasonography in predicting CL grade. METHODS: We studied 100 patients undergoing general endotracheal anaesthesia. Mallampati (MP) class, thyromental distance (TMD) and sternomental distance (SMD) were noted. Ultrasound measurements of the anterior neck soft tissue thickness at the level of the hyoid (ANS-Hyoid), anterior neck soft tissue thickness at the level of the vocal cords (ANS-VC) and ratio of the depth of the pre-epiglottic space (Pre-E) to the distance from the epiglottis to the mid-point of the distance between the vocal cords (E-VC) were obtained...
