Plain-English summary
Two horses were checked because they had trouble with their throat due to a problem in one of their guttural pouches, which are air-filled spaces near the throat. X-rays showed that one of the guttural pouches was blocked, but tests on the fluid from that pouch did not find any bacteria. During surgery, the lining of the pouch was easy to remove in one horse, but it was too firmly attached in the other horse, so they didn't try to take it out. Instead, both horses had a small opening made between the normal and affected guttural pouches to help with drainage. The exact cause of the cysts in the guttural pouches is not known.
Abstract
Two horses were examined for compression of the pharynx from the dorsal pharyngeal wall. Neither horse had a patent opening of 1 of the guttural pouches. Radiography of the guttural pouch region revealed a retropharyngeal opacity that occluded 1 guttural pouch. Organisms were not isolated on bacteriologic culture of fluid obtained from the affected guttural pouch. Surgical exploration of the guttural pouch revealed the lining to be easily removeable by blunt dissection in 1 horse; however, the lining was more firmly attached and removal was not attempted in the second horse. A fenestration between the normal and affected guttural pouch was created in both horses to allow for drainage. The etiopathogenesis of the cyst in the guttural pouches is unknown.
