A technique for reversible re-entrant cannulation of the parotid duct in sheep is described. A tube is inserted into the excretory duct via the papilla, is brought through the cheek, and connected to a three-way stop-cock positioned on the neck. A return tube from the stop-cock is passed through the cheek at a point forward and dorsal to the first tube. Sheep were maintained with such unilateral parotid cannulae for 3 mo or shorter periods. Saliva flow rates are comparable with values reported using other techniques. Removal of the tubing reverses the animal to its previous normal functioning state. This is an advantage over previously described procedures. Key words: Cannulation; parotid gland; parotid secretion; salivation; ruminants

Stensen's Duct

Introduction:Sialectasis of parotid duct is an uncommon condition characterised by abnormal dilatation of a part or whole of the Stensen's duct. It may lead to recurrent parotid infections as well as a cause of concern for the patient. Superficial parotidectomy is the accepted surgical treatment for this condition. Case Report: A case of idiopathic dilatation of parotid duct is presented. It was treated by marsupialisation of the sialectatic segment.This procedure proved to be much simpler and safer than superficial parotidectomy whilst being equally effective. Conclusion: In cases of Stensen's duct sialectasis without any abnormality of the parotid gland, marsupialisation of the ectatic segment should be the treatment of choice.

Sodium And Potassium

Rapid intra-arterial injections of radioactive iodide, sodium, and potassium have been made into the carotid artery while the parotid gland was secreting saliva at a steady rate. All three ions appeared in the saliva within a few seconds with iodide lagging slightly behind sodium and potassium. The curve for potassium was several times as long as those for sodium and iodide. With intravenous injections of the isotopes, after sufficient time had been allowed for equilibration between the blood and the parotid gland, there was an initial transient concentration of all three ions when secretion started after a rest period. The transient concentrations for sodium and potassium appeared slightly ahead of that for iodide. Potassium showed a clear second phase in its rest transient concentration.It is concluded that all three ions are able to cross the salivary duct epithelium and enter the saliva. Evidence for active transfer of potassium into the salivary duct lumen is presented.

AbstractWe report the imaging findings in a rare case of an accessory parotid gland fistula.Material and methods:An eight-year-old boy was presented with complaints of serous discharge from his left cheek since birth. As part of the radiological investigation, magnetic resonance imaging, computed tomography sialography with fistulography, and digital sialography with fistulography were performed.Results:Magnetic resonance imaging demonstrated the exact location of an accessory parotid gland but failed to demonstrate the accessory duct. The presence of an accessory gland was well delineated on computed tomography fistulography and computed tomography sialography. Fistulography revealed a small accessory parotid duct and gland. No communication between the ductal systems of both glands was demonstrated.Conclusions:In such cases, pre-operative imaging (with sialography, magnetic resonance sialography and computed tomography sialography with fistulography) is helpful for exact delineation of the ductal anatomy. To the best of our knowledge, only four previous cases of congenital accessory parotid gland fistula have been reported in the English literature.

The facial nerve divides within the parotid gland into upper temporozygomatic and lower cervicofacial branches. The two branches further subdivide and emerge from the parotid gland as five main branches. We observed a rare anomalous branching pattern of the facial nerve along with double parotid duct on the right side of a 50-year-old male cadaver. The two parotid ducts emerged at the level of the anterior border of parotid gland then united to form one single duct thereby opened into the oral cavity. The first duct (D1) emerged from the upper one third of the anterior border of the parotid gland and traversed horizontally for 9 mm to join the second duct. Knowledge of anomalous branching pattern of facial nerve and double parotid ducts may be beneficial for maxillofacial surgeons.
