Laryngocele
A laryngocele is the dilatation of the saccule of the laryngeal ventricle and is unilateral in the vast majority of cases 8.
On imaging, these lesions are generally characterized as well-defined, thin-walled, fluid or air-filled cystic lesions in the paraglottic space. Communication with the la...

Epiglottitis, also known as supraglottitis, is a life-threatening condition caused by inflammation of the epiglottis and aryepiglottic folds 1, which can lead to acute airway obstruction.
Epidemiology
The traditional age of presentation is in children of 3 to 6 years, although this has been ch...

Thyroid cartilage
The thyroid cartilage is the largest of the cartilages of the larynx, with its superior border sitting at the level of the C4 vertebra.
Gross anatomy
The thyroid cartilage consists of bilateral flattened laminae that are fused in the anterior midline to form the laryngeal prominence (Adam's ap...
Article
Intrinsic muscles of the larynx
The intrinsic muscles of the larynx can be considered in two groups:
muscles that control the inlet of the larynx
muscles that move the vocal ligaments
Gross anatomy
Muscles of the inlet
aryepiglottic muscle: lies within the aryepiglottic fold, runs from the side of the epiglottis and inser...

Cricoid cartilage
The cricoid cartilage is a ring-shaped laryngeal cartilage that sits below the thyroid cartilage and above the tracheal rings, at the level of the C6 vertebra. It is the only complete cartilaginous ring of the whole airway.
Gross anatomy
It consists of a thinner anterior portion, called the ar...
Article
Arytenoid cartilage
The arytenoid cartilages are paired hyaline cartilages that articulate with the sloping upper border of the lamina of the cricoid cartilage via the synovial cricoarytenoid joint. This joint allows movement of the arytenoid cartilages, which is vital in approximating, tensing and relaxing the voc...

False vocal cords
The false vocal cords (vestibular folds, ventricular folds, ventricular bands) are paired shelf-like structures located within the supraglottic larynx that divide the laryngeal vestibule above from the laryngeal ventricle below. They function to protect the airway and play very little if any par...
Article
Aryepiglottic folds
The aryepiglottic folds are two ligamentomuscular structures within the supraglottic larynx that function to protect the airway when swallowing.
Gross anatomy
Each aryepiglottic fold is comprised of the superior ligamentous edge of the quadrangular membrane and covering mucous membrane 1, the ...
