Epiglottic Entrapment Basic Information Definition Epiglottic entrapment occurs when aryepiglottic tissue envelops the epiglottis. Epidemiology Species, Age, Sex Most common in young racehorses Genetics and Breed Predisposition The disorder is most commonly identified in Thoroughbred and Standardbred racehorses. Between 0.7% and 2% of racehorses have epiglottic entrapment, and as many as 8% of horses with upper airway obstruction have the disorder. Risk Factors • Racing or in race training • Hypoplastic epiglottis • Upper airway inflammation Associated Conditions and Disorders Affected horses are more likely to have concurrent epiglottic hypoplasia. Epiglottic flaccidity and dorsal displacement of the soft palate may also be noted. Clinical Presentation History, Chief Complaint Most affected horses are exercise intolerant and make an abnormal upper respiratory noise during exercise. Occasionally, epiglottic entrapment is an incidental finding. Rarely dysphagia, cough, or nasal discharge are noted. Physical Exam Findings Normal Etiology and Pathophysiology • The cause is unknown. Entrapment may be precipitated by inflammation of the redundant aryepiglottic tissue. Epiglottic hypoplasia may be a predisposing factor because as many as 30% of affected horses have some degree of epiglottic hypoplasia. • Onset of hard work in racehorses has been incriminated. Diagnosis Differential Diagnosis Dorsal displacement of the soft palate Initial Database • The clinical pathology is normal. • Examination of affected horse during exercise may elicit abnormal upper respiratory noise.< div class='tao-gold-member'> Only gold members can continue reading.
