Parotid salivary duct mucocoele and sialolithiasis following parotid duct transposition.

An 11-year-old, female neutered English springer spaniel presented with recurrent episodes of mucopurulent discharge from the right eye, 17 months after parotid duct transposition, culminating in the development of a swelling over the infraorbital area. A diagnosis of parotid duct obstruction with resulting rupture of the duct and sialocele was made. On exploratory surgery, three sialoliths were removed from various sites within the duct. Surgical repair of the duct restored normal saliva flow.
