The authors describe a 2-year-old girl with a right-sided aortic arch who developed a sudden, fatal aortoesophageal fistula after prolonged placement of Montgomery salivary bypass tubes in the distal esophagus.

INTRODUCTION The lesions of the salivary ducts may be idiopathic, post- traumatic, or iatrogenic and lead to sialocele formation with persistent painful facial swelling or cutaneous fistula formation. No consensus on treatment of this condition exists: the options of treatment include needle aspiration, pressure dressings, antisialogogue therapy, radiotherapy, botulinum toxin and surgical appro...

Myoepithelioma is a rare, benign salivary neoplasm, most frequently located in the salivary gland; extrasalivary cases most commonly occur in the palate. This tumor is prone to recurrence. We present a case of recurrent myoepithelioma in the nasal cavity with a palatal fistula treated both by a palatal approach and a piriform apertural approach. The combination of these approaches widens the su...

In dogs with chronic parotid fistula, conditioned salivary reactions reinforced by food were established. After bilateral lesions of the dorsomedial part of the amygdaloid complex, the conditioned salivary reactions were greatly diminished. Also the unconditioned salivation decreased. This decrease was greater in dogs which revealed the whole syndrome of amygdalar aphagia, but it was also evide...

OBJECTIVE To describe a novel method for the removal of the salivary bypass tube (SBT) that precludes the need for extraction under general anesthesia. STUDY DESIGN Retrospective case series. METHODS/TECHNIQUE Patients who had undergone laryngectomy/laryngopharyngectomy with subsequent development of pharyngocutaneous fistula and intraoperative placement of a salivary bypass tube were inclu...

Repair of parotid duct lacerations in 2 horses is described using intraluminal silastic tubing as a stent. The duct was lacerated traumatically at the facial vessel notch (incisura vasorum facialium) in the 1st horse, and iatrogenically after removal of an intraluminal sialolith after development of infection within the duct in the 2nd horse. In both cases, a silastic tube was passed retrograde...
