What is the Aryepiglottic fold?

What is the Aryepiglottic fold?

The aryepiglottic folds extend between the arytenoid cartilage and the lateral margin of the epiglottis on each side and constitute the lateral borders of the laryngeal inlet. They are involved in physiologic closure mechanisms of the larynx and in pathologic conditions such as inspiratory stridor.

What Innervates Aryepiglottic folds?

recurrent laryngeal nerve
The aryepiglottic muscle together with the transverse arytenoid and the thyroarytenoid work as a sphincter and close the larynx as we swallow or cough. Its innervation is by the recurrent laryngeal nerve (from vagus) just like all the intrinsic muscles of the larynx except the cricothyroid muscle.

What is the vestibular fold?

The vestibular folds (false vocal cords) lie superiorly to the true vocal cords. They consist of the vestibular ligament (free lower edge of the quadrangular membrane) covered by a mucous membrane, and are pink in colour. They are fixed folds, which act to provide protection to the larynx.

What are true vocal folds?

The true vocal cords are the thickened, free edge of the cricovocal membrane, the cricovocal ligament, lined by mucous membrane 1. Together they form part of the glottis, the V-shaped aperture through which air passes. Stratified squamous epithelium lines the vocal folds.

Where are the aryepiglottic folds located in the body?

Aryepiglottic fold. The aryepiglottic folds are triangular folds of mucous membrane enclosing ligamentous and muscular fibres. They are located at the entrance of the larynx, extending from the lateral borders of the epiglottis to the arytenoid cartilages, hence the name ‘aryepiglottic’.

What is a schwannoma of the aryepiglottic fold?

A schwannoma of the aryepiglottic fold is an uncommon benign tumor. We report a rare case of a laryngeal schwannoma. The clinical, computed tomography (CT) and magnetic resonance imaging findings are presented. The tumor was located at the both aryepiglottic folds of the larynx.

Which is an adult form of epiglottis?

Supraglottitis is the adult form of epiglottitis. It is characterized by thickened epiglottis, aryepiglottic folds, and mucosal enhancement. Patients are managed with intravenous antibiotics and steroids.

What do you need to know about supraglottitis in adults?

Thickened, edematous, and enhancing epiglottis and aryepiglottic folds. This is particularly pronounced in the aryepiglottic folds. No discrete rim-enhancing fluid collections or soft tissue gas identified. Severe narrowing of the airway. Secretions just above the level of the cervical esophagus. Supraglottitis is the adult form of epiglottitis.
