Zygomatic salivary mucoceles in the dog

Zygomatic salivary mucoceles were diagnosed in 2 dogs. Ophthalmologic signs differed in both cases and reflected the position of the mucocele in relation to the orbit. Cytology of aspirated material and sialography were performed in both cases, but his enabled confirmation of the diagnosis in only one. Surgical excision of the zygomatic salivary gland, with drainage of the mucocele, was curative in both cases. Both dogs had a history of trauma to the head.
