What is Arytenoid edema?
Arytenoid swelling or edema is caused by various inflammatory and noninflammatory conditions such as gastroesophageal reflux disease (GERD), exposure to irritants, allergies, following radiotherapy, laryngitis, and hidden malignancy.
What is Arytenoid inflammation?
Arytenoid chondritis is a progressive inflammatory condition of the arytenoid cartilages in adult horses, originating as an infectious condition. Most commonly, upper airway dysfunction is reflected in poor athletic performance and respiratory stridor. Diagnosis is based on upper airway endoscopy.
What does Arytenoid mean?
Definition of arytenoid 1 : relating to or being either of two small laryngeal cartilages to which the vocal cords are attached. 2 : relating to or being either of a pair of small muscles or an unpaired muscle of the larynx.
What is the function of the arytenoids?
The arytenoid cartilages help move the vocal folds allowing tension, relaxation, or approximation of these because the vocal folds, being attached to the arytenoids, move along with them. Several intrinsic laryngeal muscles and ligaments are also attached to the arytenoids and can move them around.
What causes arytenoid swelling?
The inflammation can be caused by trauma or a low grade infection involving the arytenoid cartilage. The affected arytenoid generally is enlarged and may have an ulcer or small elevated site of granulation tissue (called a granuloma).
What is arytenoid congestion?
Arytenoid chondritis develops following trauma to the inner lining (mucosa) of the arytenoid cartilage or due to bacterial infection that affects the cartilage. Laryngomalacia (soft larynx): It is a common condition seen in babies. It is caused by the floppiness of the laryngeal tissues above the vocal cords.
Where is the Arytenoid located?
the larynx
The two light arytenoid cartilages are shaped like three-sided pyramids, and they lie in the posterior aspect of the larynx.
What is Arytenoid congestion?
What happens when Arytenoids move?
The arytenoids form the cricoarytenoid joints with the cricoid cartilage. At these joints, the vocal cords can come together, move apart, tilt anteriorly or posteriorly, and rotate. These movements help control the functions of the larynx such as the pitch of the sound.
What is the significance of the trachea being reinforced with cartilage rings?
The ‘c’ shaped cartilage rings are present in the trachea to prevent it from collapsing and they keep the trachea open for air to come in and out.
