What are arytenoids?
The arytenoid cartilages are paired pyramid-shaped structures of cartilage found in the larynx, which are essential to the production of vocal sound. They are located on the lateral part of the superior border of the lamina of the cricoid cartilage and help form the cricoarytenoid joints.
Where are arytenoids located?
the larynx
The arytenoid cartilage is located on the dorsal (back) side of the larynx above the cricoid lamina, a signet ring-shaped cartilage that lies near the bottom of the larynx.
How do you treat a swollen Arytenoid?
In the acute inflammatory stage, arytenoid chondritis cases should be treated aggressively with intravenous antimicrobials and anti-inflammatories. A tracheotomy may need to be performed if the obstruction is severe. A tracheotomy allows the upper airway to “rest” since airflow will be diverted.
What is Arytenoid congestion?
It is caused by the floppiness of the laryngeal tissues above the vocal cords. When a child with laryngomalacia breathes in, the tissues above the vocal cords fall in toward the airway and cause partial airway obstruction. This creates stridor or noisy breathing due to the voice box getting occluded.
