Laryngeal squamous cell carcinoma (staging)
Laryngeal squamous cell carcinoma staging uses the TNM staging system and actual staging is subsite (see laryngeal subsites) specific for T1-3. A rough approximation for all subsites is T1: limited to one subsite and normal cord mobility T2: more than one subsite and impaired cord mobility (bu...
Laryngocoeles refer to dilatations of the laryngeal ventricular saccule located in paraglottic space of supraglottis. On imaging, these lesions are generally characterised as well-defined, thin-walled, fluid or air-filled cystic lesions in the paraglottic space. The communication with the laryn...

Squamous cell carcinoma of the larynx
Squamous cell carcinoma of the larynx is the most common primary malignant tumor that affects the laryngeal framework (98%). Typically it is categorised by the laryngeal subsite affected, which affects presentation, treatment and prognosis. Epidemiology Male are more affected than females, an...
The thyroid cartilage is the largest of the cartilages of the larynx, with its superior pole sitting at the level of the C4 vertebrae. Gross Anatomy The thyroid cartilage consists of two laminae that are fused anteriorly in the median plane to form the laryngeal prominence. Each laminae posses...
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...
The cricoid cartilage is a ring shaped structure that sits just below the thyroid cartilage. It is the only complete cartilaginous ring of the whole airway. Gross Anatomy The anterior portion is called the arch and the posterior quadrangular shaped portion is the lamina. It articulates with th...
The arytenoid cartilages are paired hyaline cartilages that articulate with the sloping upper border of the lamina of the cricoid cartilage by the cricoarytenoid joint. This joint allows movement of the arytenoid cartilages, which is vital in approximating, tensing and relaxing the vocal folds. ...

False vocal cords
The false vocal cords (vestibular folds, ventricular folds) are paired shelf-like structures located within the supraglottic larynx that divide the vestibule above from the ventricle below. Gross anatomy The vestibular ligaments are the ligamentous component of the false vocal cords and const...
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 membrane1, the e...
