Successful control of excessive salivary flow following parotid duct transplantation by partial ligation of the transposed parotid duct at its origin in an English cocker spaniel


A four-year-and-nine-month-old English cocker spaniel, which had undergone a parotid duct transposition in the right eye for the treatment of keratoconjunctivitis sicca, was presented with excessive salivary flow and salivary intolerance. The excessive salivary flow caused the right ear and face to be constantly wet. Revision of the surgery was obtained by a partial ligation of the transposed parotid duct at its origin. Three accessory branches of the parotid duct at its origin were ligated with an excellent outcome. Only four previous cases have been reported in literature, describing similar surgery in two different breeds; however, a different amount of accessory branches was ligated on each occasion, depending on the case. How many accessory branches of the transposed parotid duct should be ligated still remains a debatable question and more clinical cases are required to draw a definitive conclusion.
