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.
对两匹马进行了检查，以确定是否存在来自咽背壁对咽部的压迫。两匹马的喉囊均无开放通道。喉囊区域的X光检查显示咽后有不透明阴影，阻塞了一个喉囊。从受影响的喉囊中获取的液体进行细菌培养，未分离出微生物。对喉囊进行手术探查发现，一匹马的囊壁可通过钝性分离轻松去除；然而，另一匹马的囊壁附着更牢固，未尝试去除。两匹马均在正常喉囊和受影响的喉囊之间造了一个开窗以利于引流。喉囊中囊肿的病因尚不清楚。
