Abstract

Guttural pouch tympanites was diagnosed in eight foals with respiratory stridor and tympanic swelling in the parotid region. Three foals were treated by transendoscopic neodymium:yttrium aluminum garnet (Nd:YAG) laser fenestration of the median septum between the guttural pouches. One foal died of pneumonia, and the other two foals recovered completely, although the fenestration later closed in one foal. Five foals were treated by creating a salpingopharyngeal fistula using transendoscopic laser irradiation: complete resolution of the tympanites occurred. Transendoscopic laser surgery in standing foals may be a reasonable alternative to conventional surgery and general anesthesia for correction of guttural pouch tympanites.
