Abstract
A subepiglottic cyst, found in a young thoroughbred horse which showed respiratory noise during exercise, was resected by means o f a wire snare fed with high current while viewing under oral endoscopy. In comparison with the laryngotomy and pharyngotomy approaches reported elsewhere in the literature, the present method proved to be safer, inflicted less surgical stress, and required a shorter recovery period. The histopathological study did not clarify the tissue origin but the location o f the cyst suggested it to be derived from the thyroglossal duct.
