A five-year-old, female, spayed beagle with a history of unilateral epiphora of several months' duration as a result of inadequacy of the lacrimal drainage system was treated successfully with a new surgical method of parotid duct transposition. Data from complete preoperative ophthalmological examination, surgical technique, postoperative treatment, contrast radiography and histological examination were recorded. Absence of complications and complete patency of the stoma at 30 days after surgery confirmed the validity of this new technique. The use of an anatomic duct may be advantageous compared with the current techniques of conjunctivorhinostomy, conjuntivobuccostomy and conjunctival maxillary sinusostomy for the treatment of epiphora in the dogs caused by inadequacy of the lacrimal drainage system.
These findings demonstrate that the LTN and TDN can be used to neurotize injured contralateral brachial plexus nerves and obtain successful reinnervation in cats.
