What is Epiglottic entrapment in horses?

Inflammation or anomalies in the horse’s airway structures can lead to entrapment, which occurs when the epiglottis becomes stuck on tissue called the aryepiglottic fold. A horse with epiglottic entrapment makes a gurgling noise while working and may be unable to sustain athletic effort due to reduced airflow.

What causes Epiglottic entrapment?

This disease is secondary to the epiglottis being trapped below the aryepiglottic fold. The cause is either secondary to an excess amount of aryepiglottic tissue or inflammation of the aryepiglottic tissue. Clinical signs include rattling, wheezing, or gurgling when the horse is exercising.

What is Epiglottic Retroversion horse?

Epiglottic retroversion should be considered as a differential diagnosis for a horse which makes a gurgling, inspiratory noise and which is suffering from poor performance. Videoendoscopy during high speed treadmill exercise is required to make a definitive diagnosis.

Do horses have epiglottis?

Introduction. The epiglottis is a triangular-shaped, elastic cartilage that helps to protect the airway during swallowing. The tip of the triangle points rostrally and in a normal horse, the epiglottis sits dorsal to the soft palate during breathing.

For partial removal of the epiglottis, a laser or other method of cutting is used to remove a portion of the epiglottis and control any bleeding.

What is responsible for Roarer syndrome in horses?

RLN is caused by paralysis of one or both of these cartilages (called the arytenoid cartilage) due to lack of innervation causing atrophy (wastage) to the muscle that moves the arytenoid cartilage. The left arytenoid cartilage is the most common side affected (up to 95%).

What is Chondritis horse?

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.

When is the epiglottis open?

It stays open during breathing, allowing air into the larynx. During swallowing, it closes to prevent aspiration of food into the lungs, forcing the swallowed liquids or food to go along the esophagus toward the stomach instead. It is thus the valve that diverts passage to either the trachea or the esophagus.
