What does Transglottic mean?

trans·glot·tic (trans-glot’ik), Vertical crossing of the glottis, as in the spread of carcinoma from the supraglottic to the infraglottic area.

What is CA larynx?

Laryngeal cancer is cancer of the larynx, or voice box. Laryngeal cancer symptoms include voice changes, such as hoarseness, and a sore throat or cough that doesn’t go away. Treatment may include surgery to remove part or all of the larynx, called a laryngectomy.

What is involved in a laryngectomy?

In a partial laryngectomy, only part of the larynx will be removed. In a total laryngectomy, your entire larynx is removed. Part of your pharynx may be removed too. Your pharynx, or your throat, is the passage between your nasal cavity and esophagus. In some cases, your lymph nodes may also be removed.

What causes supraglottis?

Epiglottitis (supraglottitis) is caused by a potentially life-threatening infection that produces upper airway swelling and obstruction. Formerly, the most common etiology was Haemophilus influenza type B (HIB), and the disease usually occurred in children 2 to 8 years of age.

What is the subglottic area?

Listen to pronunciation. (SUB-glah-tis) The lowest part of the larynx; the area from just below the vocal cords down to the top of the trachea. Enlarge.

What is Paraglottic space?

Background Paraglottic space (PGS) is a connective tissue compartment of the larynx and is important in the extension of laryngeal cancer. It communicates with the preepiglottic space superiorly and with the extralaryngeal region inferiorly through the gap within the cricothyroid membrane.

How is Videostroboscopy done?

Videostroboscopy can be performed with either a flexible fiberoptic endoscope or a rigid scope. A thin, flexible fiberoptic telescope is passed gently through the nose into the pharynx or a rigid scope is gently placed towards the back of your mouth allowing visualization of the vocal cords and larynx (voice box).

Is a Laryngocele cancerous?

Laryngocele may sometimes be the source of laryngeal cancers (3). These cancers can be particularly serious due to the deep invasion in the paraglottic space. In 1987, Birt reported that the ventricles in patients operated on for laryngeal cancer were significantly deeper than those with a normal larynx (12).
