“…13,14 Alternatively, subepiglottic cysts can be treated by means of intralesional formalin administration. 15 The etiology of the various epiglottic abnormalities identified in the horses in the present study was not determined; however, inflammation of the subepiglottic and pharyngeal mucosa is thought to be a predisposing factor in the development of subepiglottic granulomas and cysts. 7 Thus, steroidal and nonsteroidal anti-inflammatory drugs are commonly used intraoperatively and postoperatively in conjunction with surgical management of these abnormalities to treat existing and surgically induced subepiglottic inflammation.…”

Summary A 5‐month‐old colt with a history of nonpainful left‐sided facial swelling present since birth was presented for evaluation and treatment. A diagnosis of congenital parotid salivary duct atresia was made, and surgical correction was attempted but was unsuccessful. Follow‐up treatments consisted of repeat intralesional injection of 10% neutral‐buffered formalin. The horse developed ventral mandibular abscessation with multiple draining tracts secondary to this treatment; however, no other significant complications occurred and a cosmetic outcome was achieved.

“…A reported alternative low cost option for removal of SECs is repeated intralesional formalin administration performed in the standing sedated horse. Successful treatment using this technique in a 4‐year‐old mare with a SEC has been reported but additional clinical cases are required to determine success rate, cyst recurrence and possible adverse effects of formalin (Dougherty and Palmer ). This technique was only described near the end of this case series and was therefore not attempted.…”

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.

Use of intralesional formalin administration for treatment of a subepiglottic cyst in a horse

Abstract: Findings suggest that intralesional formalin administration for treatment of subepiglottic cysts may be a minimally invasive, economically suitable alternative to surgical treatments.
