“…In contrast with the present study, Tulleners () reported that all 10 horses with SECs demonstrated respiratory noise, with additional complaints of coughing (30%), exercise intolerance (20%) and dysphagia (20%). Furthermore a study investigating epiglottic abnormalities in mature nonracehorses reported clinical signs of coughing (n = 2) and dysphagia (n = 1) in 3 horses with SECs (Aitken and Parente ). The discrepancy in prevalence of clinical signs seen in this case series compared to others is likely to be due to the difference in age of the study populations, with our population being generally younger.…”

“…The condition is most commonly diagnosed in young Thoroughbred (TB) and Standardbred racehorses and is thought to be congenital (Fulton et al 2012), with cysts arising from a remnant of the thyroglossal duct (Kelmer et al 2007). However, it has also been reported that SECs may be acquired secondary to inflammation or trauma and they are occasionally found in older horses with no previous history of upper respiratory tract problems (Davenport-Goodall and Parente 2003;Aitken and Parente 2011).…”

Summary Subepiglottic cysts (SECs) are an infrequent cause of upper respiratory tract noise and exercise intolerance in horses. They may also be associated with no clinical signs and be an incidental finding during routine upper airway endoscopy. The aim of this study was to assess the effect on performance of horses undergoing surgical removal of SECs. The case records of 15 horses (1995–2009) diagnosed with SECs were retrieved. Eleven (73%) of the 15 horses included in the study were Thoroughbred racehorses. Eleven (73%) of the 15 horses had no preoperative clinical signs related to the SECs, with the remaining 4 (27%) having a respiratory noise (n = 4), nasal discharge (n = 1), difficulty swallowing (n = 1) or a cough (n = 1). Endoscopic examination in the standing horse was diagnostic in 93% (n = 14) of horses. Nine (82%) of the 11 Thoroughbred horses were yearlings, of which only one horse (11%) presented with clinical signs consisting of a respiratory noise and nasal discharge. Four of the 11 (36%) Thoroughbred horses were found to have concurrent epiglottic entrapment. Surgical removal was successful in all cases. Eight of the 11 (73%) Thoroughbred horses in this study raced following SEC removal. The majority of SECs are identified during routine endoscopic examinations and are not associated with clinical signs. The prognosis following surgical removal of SECs is good and future performance does not appear to be affected.

“…Persistent epiglottic entrapment (EE) is a common abnormality in the racehorse and the mature nonracehorse . EE affects 0.9%‐3% of thoroughbred racehorses examined for suspected upper respiratory obstruction, resulting in clinical signs of exercise intolerance, poor performance, respiratory noise, and coughing .…”

“…However, when elongation of the soft palate occurs the epiglottis is lying ventral to the soft palate and it is therefore completely lost from the observer's view. 34 Rostral displacement of the palatopharyngeal arch (RDPA), over one or both of the corniculate processes of the arytenoids that appears malformed, does not abduct well, or both. Abnormal arytenoid movement in most cases might be a result of abnormal anatomy of laryngeal cartilages and muscles, not restriction by the palatopharyngeal arch.…”

Background: Upper respiratory tract (URT) obstructive disorders are a common problem among horses and are often associated with poor performance and respiratory noise during exercise. Aim: The study is proposed to visualize the upper respiratory tract of horses and donkeys by endoscopic examination, aiming to highlight and clarify the disease conditions that causing respiratory distress and subsequenly affect negatively on the work and sports ability of these animals. Materials and Methods: The present study employed the endoscopic examinations on the upper respiratory tract of 45 stallions, 30 mares, 10 foals and 38 donkeys, suffered from upper respiratory tract distresses. These animals were of various ages and weights. Results: Investigation of these animals proved that the upper respiratory tract disorders were numerous in horses and prevailing in donkeys. The pharyngeal region was more affected than the other parts of the upper respiratory tract. In addition, squamous cell carcinoma, cyst and granuloma in the guttural pouches have been taken care of, regardless of its rare occurrence. The ethmoidal glandular cyst acini, pharyngeal mycosis, and pharyngeal tonsillitis were considered critical evidences for the study. Conclusion: Endoscopy of the upper respiratory tract of horses and donkeys should be a standard diagnostic technique for all upper respiratory disorders in equine.
