The glottic structures include the true vocal folds, and the subglottis extends from just below the true vocal folds to the inferior border of the cricoid
3 Second, compression on the cricoid
cartilage during intubation will anatomically fix the superficially distributed hypoglossal nerve at the mandible angle, and if the intubation is performed in this condition, the nerve may be hyperextended.
scanning at the level of the cricoid
membrane in which direct visualisation of the passage of the endotracheal tube through the vocal cords is possible.
Aetiological factors such as calcification and/or ossification of laryngeal cartilages and ligaments (thyroid cartilage, cricoid
cartilages and the pre-vertebral ligament)may also hinder the interpretation of plain films.
The desquamating lesions on her posterior pharyngeal wall extended to the bilateral arytenoids, posterior cricoid
region, and piriform sinuses, as well as the subglottic region (figure).
The butterfly-shaped thyroid gland is located in the neck, posterior to the larynx and immediately inferior to the cricoid
pressure was needed to bring the posterior portion of vocal cords into the visualization field.
The esophagus spans approximately 25-30 cm from the lower border of the cricoid
cartilage to the gastroesophageal junction.
There even exists a "NG tube syndrome" (5), the pathophysiological mechanism of which is thought to be paresis of the posterior cricoarytenoid muscles secondary to ulceration and infection over the posterior lamina of the cricoid
cartilage is a hypoechoic, inverted U structure inferior to the thyroid cartilage; the posterior acoustic shadow corresponds to the airway Fig.
Superiorly it was extending up to the level of ramus of mandible, inferiorly extending up to the level of cricoid
cartilage and medially extending into the left paraphryngeal space indenting the left lateral pharyngeal wall causing mild asymmetrical narrowing, laterally producing bulge in skin of neck on left side.
Early intubation, correctly applied cricoid
pressure and use of a smaller-sized endotracheal tube
