Transendoscopic Nd:YAG Laser Surgery for Treatment of Epiglottal Entrapment and Dorsal Displacement of the Soft Palate in the Horse

Transendoscopic neodymium:yttrium-aluminum-garnet (Nd:YAG) laser was used to treat 12 standing horses with epiglottic entrapment (EE) or dorsal displacement of the soft palate (DDSP), or both. In four horses, transendoscopic laser staphylectomy was performed. The most common presenting complaints were respiratory stridor, cough, and exercise intolerance. Ten horses with EE healed without epiglottic complications; in one horse, partial adhesion of the aryepiglottic fold to one side of the epiglottis was corrected surgically through a laryngotomy incision. One horse with DDSP had no further signs, one continued to have continual DDSP, and two had induced DDSP. Transendoscopic Nd:YAG laser proved to be a feasible means of correcting EE and selected cases of DDSP.
