Dogs have four pairs of larger glands (parotid, sublingual, zygomatic and submandibular) and also contain numerous minor salivary glands distributed throughout the oral cavity, such as the lips, cheek, tongue, palate, pharynx and esophagus. The name mucocele is given for the abnormal accumulation of saliva in the salivary glands, forming a dilation of the gland in the place that can lead to respiratory compromise of the affected animal. Disorders in the salivary glands are not frequent in dogs, they present a low incidence, of approximately 0.3%. The clinical signs associated with salivary mucocele depend on its location, and may present different symptoms, depending on the affected gland. The resolution is surgical, is the most appropriate method to reduce the problem and with better results without occurrence of relapses. The objective of this work was to perform a review of the literature on pharyngeal mucocele in dogs. [ABSTRACT FROM AUTHOR]
